The chloroform fraction of the extract at the dose of 200 mg/kg body weight, like the standard anti-diarrhoeal agent (hyoscine butylbromide), caused a significant (p < 0.05) reduction in the intestinal fluid sodium ion concentration of rats in group 7 (209.00 ± 11.40) when compared to the value (227.00 ± 3.46) obtained for rats in the

castor oil-treated control group. As shown in Fig. 3, the methanol and the chloroform fractions of the extract RAD001 cost at the tested doses (100 and 200 mg/kg body weight of each) significantly (p < 0.05) reduced the intestinal fluid potassium ion concentration of rats in groups 4, 5, 6 and 7 when compared to that of the rats in the castor oil-treated control group (group 2). The effects observed were dose-related with the intestinal fluid potassium ion concentration as 6.15 ± 1.75, 6.20 ± 1.70, 6.20 ± 1.23 and 5.65 ± 1.05 for rats in the 100 and 200 mg/kg body weight of the methanol fraction-treated groups (groups 4 and 5), 100 and 200 mg/kg body weight of the chloroform fraction-treated groups (groups 6 and 7) respectively when compared to the value (11.40 ± 2.98) obtained for rats in the castor oil-treated control group. The effects of the methanol and the chloroform fractions of the extract at the tested doses were comparable to that of the standard anti-diarrhoeal agent (hyoscine butylbromide) as shown in Fig. 3. The results of the qualitative and quantitative phytochemical analyses

of the chloroform and the methanol fractions of the chloroform–methanol extract of the leaves of P. americana showed, in both fractions of the extract, the presence and percentages of such bioactive constituents buy MK0683 as: alkaloids (2.67 ± 0.13% and 2.57 ± 0.06% in the chloroform and the methanol fractions respectively), flavonoids old (3.20 ± 0.17% and 2.95 ± 0.14% in the chloroform and the methanol fractions respectively), saponins (2.15 ± 0.08% and 2.23 ± 0.09% in the chloroform and the methanol fractions respectively), tannins

(2.48 ± 0.11% and 2.73 ± 0.13% in the chloroform and the methanol fractions respectively) and steroids (1.37 ± 0.04% and 1.10 ± 0.03% in the chloroform and the methanol fractions respectively). This indicates that the bioactive constituents present in the chloroform–methanol extract of the leaves of P. americana resided more in the chloroform fraction than in the methanol fraction. Reducing sugars, resins and acidic compounds were found to be absent in both fractions of the extract. The anti-diarrhoeal effect of both fractions of the extract shown in the present study could be, in part, due to the presence of tannins, alkaloids, saponins, flavonoids and steroids. In other words, it is possible that flavonoids and steroids, acting dually or in combination with other phytochemicals, produced the observed anti-diarrhoeal effect of both fractions of the chloroform–methanol extract of the leaves of P. americana.

The primary endpoints of the study were antibody titers to yellow fever in mIU/mL and categories (seropositive: selleck inhibitor titer higher than

2.7 log10 mIU/mL or reciprocal dilution higher than 10). Seroconversion was defined as quadrupling of pre-vaccination antibodies against yellow fever. Serologic testing for rubella antibodies (ELISA, Enzygnost® Anti-Rubella-Virus/IgG, Dade Behring, Germany) and for mumps antibodies (ELISA, Enzygnost® Anti-Parotitis-Virus/IgG, Dade Behring, Germany) were performed at the Respiratory Virus Laboratory of Instituto Oswaldo Cruz (FIOCRUZ, Rio de Janeiro), and the results expressed in International Units per milliliter of serum (IU/mL). The primary endpoints for rubella were post-vaccination antibody titers in IU/mL and categories (non-reactive: <4.0 IU/mL; inconclusive: 4.0–6.5 IU/mL; reactive: >6.5 IU/mL). For mumps, sera with antibody titers ≥231 U/mL were considered reactive, implying that borderline Galunisertib research buy titers were considered seropositive. Both for rubella and for mumps, seroconversion was defined as seropositivity in subjects who were non-reactive before vaccination. The proportion of seroconversion, the

geometric mean titer (GMT) and proportion of adverse events after vaccination were compared across groups defined by types of yellow fever vaccine and interval between vaccinations. The statistical significance of differences in proportions was analyzed by chi-square test, whereas for the differences in the means of antibody

titer logarithms the Student’s t test was used. Reverse cumulative distribution plots were constructed to display the complete range of serologic data. The level of significance was 5%. Data were analyzed using SPSS version 13.0 (SPSS, Inc., Chicago, IL). The complete cohort (“intention-to-treat”) Sodium butyrate for analysis of adverse events included children with data on reactogenicity, even those who failed to adhere to the study protocol. For the analysis of immunogenicity, the cohort consisted of all subjects randomized to YFV types, keeping subjects in the groups to which they were randomly assigned. The interaction of the MMR vaccine and yellow fever was evaluated by comparing the proportions of seroconversion for yellow fever in individuals in subgroups defined by the interval between vaccinations. Children without post-vaccination serological test, or who violated eligibility criteria were disregarded in “per-protocol analysis”. With this approach, analysis of immune response considered the vaccine actually administered, regardless of randomization group. The probability of seroconversion was adjusted for the covariates of interest (age, sex, pre-vaccination seropositivity, time between pre- and post-vaccination blood collection, and comorbidity) in a logistic regression model.

Studies meeting the eligibility criteria were assessed for methodological quality using a 7-item checklist based on the STROBE guidelines (Pengel et al 2003): use of a representative sample, having a defined sample, use of blinding, having a follow-up rate greater than 85%, appropriate choice of outcome measures, reporting outcome data at follow-up, and control for confounding via statistical adjustment. Screening for eligible studies, methodological quality assessment, and data extraction were conducted independently by two assessors with disagreement resolved by discussion. Data extracted from each study included:

descriptive data on gender, sample size, age, and source of participants (ie, patients and clinicians); verbal, nonverbal and/or interaction style factors; and the association estimates (eg, correlation value) between communication factors

Compound Library high throughput and Crizotinib price satisfaction with care. Correlations between communication factors and satisfaction that were reported as Pearson’s r, Spearman’s rho or Pointbiserial correlation were grouped as verbal, nonverbal and interaction style factors. Meta-analysis was carried out for homogeneous constructs. Pooled analyses were performed using random-effects for trials presenting an I2 of 50% or more (Higgins et al 2003). Correlation values were reported on a common –1 to 1 point scale with 95% CIs. Analytic softwarea was used to conduct all analyses. Correlations were considered poor for values 3-mercaptopyruvate sulfurtransferase < 0.21, fair for values ≥ 0.21 but < 0.41, moderate for values ≥ 0.41 but < 0.61, substantial for values ≥ 0.61 but < 0.81, and high for values ≥ 0.81 (Landis and Koch 1977). Individual communication factors that could not be pooled were presented separately. Factors used by clinicians were categorised by two assessors using the Verona medical interview classification, which is based on clinician interview performance considering its main functions and the corresponding patient/ clinician-centred interview techniques (Del Piccolo et al 2002). Disagreements were resolved by discussion. This categorisation allowed data synthesis,

given that different studies employed different systems to code communication factors (Zimmermann et al 2011, Zimmermann et al 2007). The Verona medical interview classification (Del Piccolo et al 2002) categorises clinician responses during the interaction as: information gathering (ie, closed and open questions used by clinicians), patient facilitating (ie, clinicians using facilitators, transitions, and conversation), patient involving (ie, clinicians asking for information and checking for clarification), patient supporting (ie, responses of clinicians supporting, agreeing, or reassuring), and patient education (ie, clinicians informing about the condition or psychosocial issues). The database searches yielded a total of 3414 titles, of which 27 studies in 28 publications were included in the review (Figure 1).

Dans le suivi des patients sclérodermiques, l’échographie cardiaque doit être annuelle et les patients à risque doivent passer un cathétérisme cardiaque droit dans les meilleurs délais. L’HTAP n’est pas la seule forme d’HTP chez les patients selleck inhibitor sclérodermiques, qui peuvent être touchés par une fibrose pulmonaire responsable d’une HTP secondaire ou peuvent avoir une dysfonction diastolique du ventricule

gauche. En absence de fibrose pulmonaire, l’HTAP peut être également observée chez les patients avec un lupus érythémateux, une connectivite mixte, un syndrome Gougerot Sjögren, une polyarthrite rhumatoïde ou une polymyosite mais sa prévalence reste inconnue – probablement plus basse que celle associée à la sclérodermie. L’HTAP est une complication rare de l’infection par le VIH avec une prévalence estimée de 0,5 % [24]. Depuis l’introduction des thérapies antirétrovirales, puis selleck screening library du traitement spécifique de l’HTAP dans la pratique courante, le pronostic de la maladie s’est

amélioré progressivement et, à ce jour, nous pouvons même constater des normalisations hémodynamiques chez les patients HTAP-VIH [24]. Le mécanisme de ce phénomène n’est pas clair : le virus n’étant pas été retrouvé au niveau de l’endothélium pulmonaire, l’hypothèse principale incrimine un processus inflammatoire indirect par une augmentation des cytokines pro-inflammatoires, des facteurs de croissance ou de l’endothéline, entraîné par le virus [24]. L’hypertension porto-pulmonaire est retrouvée chez 2 à 6 % des patients ayant une hypertension portale [25]. L’apparition de cette forme d’HTAP

est indépendante de la gravité de la maladie hépatique, mais le pronostic à long terme dépend de celle-ci et de click here l’hémodynamique au cathétérisme cardiaque droit. Par rapport à l’HTAPi, les données concernant la survie sont discordantes entre les registres français et américain : une meilleure survie vs HTAPi dans le registre français et le contraire dans le registre américain REVEAL [25] and [26]. Cette différence provient probablement du recrutement des patients, avec aux États-Unis des patients référés pour une transplantation hépatique ayant une cirrhose grave, et en France, des patients avec une cirrhose modérée [25] and [26]. Grâce aux progrès médicaux de ces dernières années, de plus en plus de patients avec une cardiopathie congénitale atteignent l’âge adulte. On estime qu’environ 10 % de ces patients ont une HTAP associée. Pour faciliter et homogénéiser le diagnostic et par conséquence la prise en charge, une nouvelle classification des HTAP associées à des cardiopathies congénitales a été proposée lors du congrès de Nice en 2013 (encadré 2) [1].

Surface solid dispersion had been established as a successful method to improve the dissolution rate and the solubility of poor soluble drugs. In the present study, the surface solid dispersion technique was applied in order to improve the dissolution rate of Irbesartan. The carriers used were microcrystalline cellulose, crospovidone, croscarmellose sodium, sodium starch glycolate, microcrystalline cellulose and potato starch. The samples were prepared at various drug-to-carrier weight ratios by co-evaporation method. The prepared

SSDs were characterized by using FTIR, BMS-907351 DSC, P-XRD, SEM and in vitro dissolution. Irbesartan (IBS) was obtained as a gift sample from Dr. Reddy’s Laboratories Ltd. (Hyderabad, India). The super disintegrants (SD) crospovidone (CP), sodium starch glycolate (SSG), potato starch (PS), croscarmellose (CC), microcrystalline cellulose (MC) and solvents used were obtained from S D Fine Chem. Ltd. The SSD of IBS and SD were prepared by solvent co-evaporation method. The required amount of IBS was dissolved in sufficient amount of methanol. The SD was dispersed in the IBS solution. The different ratios of drug and SD were shown in Table 1. The mixtures were sonicated for 15 min to ensure the intimate mixing. The solvent was then removed, using rotary vacuum evaporator at 50 °C. The residue GW3965 datasheet obtained was dried at 50 °C overnight. The dried mass was pulverized and passed through 80/170

mesh sieves. The products were kept in desiccators for further study. The accurately weighed amount of IBS and either SD at

1:1, 1:5 and 1:10 IBS-to-SD weight ratios were thoroughly blended by tumbling for a period of 30 min. The physical mixtures were freshly prepared prior to analysis. P-XRD patterns of the samples were recorded, using X-ray diffractometer, (RigakuMiniFlex) Advance with Cu-Kα (Ni-filter), radiation (λ = 1.5418 °A). The experiments were carried out at room temperature under the following conditions: voltage 20 kV, current 20 mA, 2θ angle range 3–60 with scanning speed 5°/min. Samples of individual components like Pure IBS, pure CP and SSD of IBS-CP combination (1:10) were weighed directly in pierced aluminum pans (5–10 mg) and scanned in the 20–200 °C temperature range under nitrogen flow of 25 mL/min with a heating rate of 10 °C/min using a DSC (Mettler CYTH4 Toledo AG, Analytical, Switzerland) apparatus. FTIR–spectra of samples of individual components as well as each IBS–SD combination (1:10) were recorded in KBr medium pellets using FTIR spectrophotometer (IR affinity-1 CE, Shimadzu, Japan). The scan was performed in the range of 400–4000 cm−1. The surface morphology of samples was determined by using an analytical SEM (Hitachi S-34000N, Japan). The samples were lightly sprinkled on a double-sided adhesive tape stuck to an aluminum stub. The stubs were then coated with gold to a thickness of about 10 Å under an argon atmosphere using a gold sputter module in a high vacuum evaporator.

Then, the animals were treated with extract or vehicle. Ten minutes after the treatment with the extracts, maltose solution (2 G/Kg) was given to the animals. 30, 60 and 120 min after the administration of maltose, plasma glucose levels were estimated using GOD-POD method. Acarbose (3 mg/kg) was used as positive control. All tests were performed

after approval by the animals ethical committee of Entomology Research Institute, Loyola College, Chennai and in accordance with the disciplinary principles and guidelines of the Committee for http://www.selleckchem.com/products/azd9291.html the Purpose of Control and Supervision of Experiments on Animals (CPCSEA). High performance liquid chromatography fingerprint of alkaloids in EEA was performed using Waters HPLC system (Waters HPLC, USA) equipped with two pumps (Waters Pump 515) and a UVeVisible detector (Waters 2489), operated by Empower 2 software. A reversed phase C18 column (Symmetry, 250 × 4.6 mm; particle size ¼ 5 mm). The column temperature was maintained at 30 C and the injection volume was 10 ml. The elution was isocratic in the

solvent mixture of acetonitrile: acetic acid: water (18:2:80) at the flow rate of 0.8 ml/min. The run time was less than 20 min High Performance Liquid Chromatography (HPLC) is one mode of chromatography; the most widely used analytical technique. HPLC utilizes a liquid mobile phase to separate the components of a mixture. These components (or analytes) are www.selleckchem.com/products/byl719.html first dissolved in a solvent, and then forced to flow through a chromatographic column under a high pressure. In the column, the mixture is resolved into its components. The interaction Non-specific serine/threonine protein kinase of the

solute with mobile and stationary phases can be manipulated through different choices of both solvents and stationary phases. As a result, HPLC acquires a high degree of versatility not found in other chromatographic systems and it has the ability to easily separate a wide variety of chemical mixtures. Antioxidant activity performed using EEA is listed in Table 1. In DPPH free radical scavenging activity, EEA was found to show high percentage of inhibition (54.29%) at 1000 μg/ml and a moderate percentage of inhibition (47.81%) at 500 μg/ml respectively. It is evident from the study, that the investigated extracts have the ability to quench free radicals. The extract showed dose dependent DPPH radical scavenging activity. Hydroxyl radical scavenging activity of EEA is shown in Table 2. EEA showed high activity 71.15% at 1000 μg/ml followed by a second high activity 61.5% at 500 μg/ml. Hydroxyl radical is an extremely reactive species formed in biological systems implicated as highly damaging in free radical pathology, capable of damaging almost every molecule found in the living cells. This radical has the capacity to join nucleotides in DNA and cause strand breakage, contributing to aging, carcinogenesis, mutagenesis, cytotoxicity and several other diseases.

A mixed inflammatory cell infiltrate, granulation-like tissue, focal calcification, ossification, and myxoid

change might be present. Electron microscopy shows a mixture of cell types in a dense collagenous matrix, with no glandular or mesothelial differentiation.1 Morphology, histology, and immunohistochemical analyses are necessary for equivocal cases. In this reported case, the fibrous pseudotumor was located on the penile shaft, and complete excision is curative, as these lesions behave in a benign fashion once excised.1 When testicles are involved, local excision of these lesions with sparing of testicles is standard. In equivocal cases, frozen section biopsy has been reported in aiding management and avoiding radical surgery. However, radical orchiectomy is often necessary for fibromatous periorchitis, when tunics are too diffusely involved

for preservation of testicular tissues.3 Clinical Bleomycin order recurrence has been hypothesized in incomplete excisions of these lesions; however, there have been no reports of recurrence, and certainly there have been no cases demonstrating metastatic potential. A penile lump with a history of previous trauma should prompt the physician to consider the differential of fibrous pseudotumor. In the setting of operative repair of penile fracture, if dissection is difficult and a fibrous mass is identified, one should consider the diagnosis of fibrous pseudotumor. Excision of the lesion and repair of fracture should provide definitive treatment. “
“Penile abscesses are an uncommon urologic condition and have been described in association with penile trauma, in the presentation click here of disseminated infection, or in association with underlying disease such as poorly controlled diabetes mellitus. The most commonly implicated organisms in penile abscess include Staphylococcus aureus, Streptococci, Fusibacteria, and Bacteroides. 1 Penile abscesses may be Resminostat diagnosed with various imaging modalities,

including magnetic resonance imaging (MRI), computed tomography (CT), and ultrasound. Such modalities may be used to concurrently treat penile abscesses; however, surgical evacuation and antibiotic therapy remain first line. We present a unique case of penile abscess in a 45-year-old male patient occurring after injection of amphetamine into the penis. We report a case of penile abscess in a 45-year-old man who presented 1 week after self-injection of amphetamine into the dorsal aspect of his penis. The penis was chosen as an injection site in the absence of suitable peripheral veins; a used syringe needle was utilized for drug injection. On presentation to the emergency department, the patient had a fluctuant necrotic area, approximately 2 × 3 cm at the base of the dorsal aspect of his penis associated with moderate penile shaft oedema (Fig. 1). This patient had a history of intravenous (IV) drug use in the absence of a significant medical history or sexually transmitted disease.

In addition, participants could attend government health services for investigation and management of any illnesses between booked study visits. A record was kept of investigations and treatments given through these other health services. The

primary objective Ku-0059436 cell line of this analysis was to evaluate the association of malaria parasitaemia and helminth infection with antibody responses against HPV-16 and HPV-18 one month (Month 7) and six months (Month 12) after the last scheduled vaccine dose in African females aged 10–25 years. Potential participants were recruited from schools, colleges and family planning clinics in Mwanza, and invited to attend a screening visit for eligibility approximately one month prior to enrolment. Prior to screening, informed consent was obtained from participants aged 18–25 years. For participants aged 10–17 years, we sought consent from a parent or legally authorized representative, as well as assent LY2157299 ic50 from the participant. Participants were eligible for enrolment if they were aged 10–25 years at the time of first vaccination, HIV

negative, not pregnant, had not had more than six lifetime sexual partners, were free of obvious health problems as established by medical history and examination, had no history of neurologic disorders and were willing to use contraception or to abstain from sex if sexually active for 30 days prior to vaccination and for two months after completion of vaccination. The enrolment was age-stratified, with one-third of participants in the 10–14 years age-stratum and the remainder in the 15–25 years age-stratum. Study procedures for the HPV 021 trial have been described in detail elsewhere [12]. In brief, the HPV vaccine and placebo were administered intramuscularly into the deltoid muscle of the non-dominant

arm at the Month 0 visit and again at Month 1 and Month 6 visits. Sociodemographic characteristics were collected at Month 0 in face-to-face interviews using standardized questionnaires. Blood samples were collected at Months 0, 2, ADP ribosylation factor 7 and 12 to evaluate antibody responses against HPV-16 and HPV-18 by enzyme-linked immunosorbent assay (ELISA). In order to test for helminth infection and malaria parasitaemia at Month 7, participants provided (i) a blood sample for the diagnosis of malaria, (ii) a first void urine sample for the diagnosis of Schistosoma haematobium and (iii) three separate stool samples (during the week following the Month 7 visit) for the diagnosis of Schistosoma mansoni, Ancylostoma duodenale (hookworm), Strongyloides stercoralis, Ascaris lumbricoides, Trichuris trichiura and Taenia spp. Participants who tested positive for malaria or helminth infections were provided with treatment by study clinicians at a subsequent study visit. Pairs of thick and thin peripheral blood films from each patient were stained with Giemsa stain in Mwanza, and examined by light microscopy at NIMR in Mwanza, and confirmed at LSHTM.

, 2007 and Södergren et al., 2008), smoking (Manderbacka et al., 1999 and Molarius et al., 2007), social support (Molarius et al., 2007) and vegetable consumption (Manderbacka et al., 1999), SP600125 which suggests that these cross-sectional associations found in the previous studies were not heavily confounded by other factors or reverse causation. Social support in 1991 is strongly related to health in 2000, but not in 2010. This is at least partly because people without support in 1991 move out of this category over time. In contrast, heavy smoking in 1991 is more strongly related to health in 2010 than in 2000, which is likely because more people have smoked for a longer time.

The analysis also shows the importance of adjusting for gender and

age when studying health impacts of drinking, as the coefficient was otherwise confounded. Similarly, the estimated effect of friend relations was confounded by age (younger people have both more friends and better health). The major strength of this study is its prospective design. Autophagy Compound Library While previous research on the relation between lifestyle and self-rated health is predominantly cross-sectional, the focus on individual-level change in health reduces the risk of confounding and reverse causality, and increases the credibility of causal interpretations. The drinking variable is admittedly weak, and a more detailed variable could give other results as regards drinking behaviour. Another limitation is that the sample is too small to explore mediators, and hence to understand the processes behind the observed (gross) effects. Importantly, the effects on health in 2000/2010 may reflect long-term effects of behaviour but also persistence in behaviour with short-term effects: For example, the effect of smoking in 1991 may be a long-term effect, or it may reflect isothipendyl that those who smoked in 1991 are more likely to smoke in 2000 and 2010. Larger sample sizes are needed to study the effects of different over-time trajectories in life-style behaviours. Among people with similar initial health, we find that smoking, exercise, social support and vegetable consumption are associated to self-rated global health 10 and/or 20 years later. There

is however no evidence of such associations for drinking behaviour (as measured here) or for frequent family and friend contacts. The authors declare that there are no conflicts of interests. “
“Public policy is a critical component of population health interventions (Hawe and Potvin, 2009) and offers an important opportunity to address the rising public health concerns of child and adolescent obesity (Story et al., 2009b). Rates of overweight and obesity have increased over the last two decades (Shields, 2006a, Tremblay and Willms, 2000 and Willms et al., 2003) and have significant health (Whitaker et al., 1997, Must et al., 1999, Rocchini, 2002 and Biddle et al., 2004) and economic implications (Kirk et al., 2011, Kuhle et al., 2011 and Tran et al., 2013).

Pair feeding of control mice, instead of ad libitum access to an isocaloric control diet, would have further strengthened our design by controlling for potential effects of amount of rations consumed. We predicted that undernourished mice would be more susceptible to rotavirus replication and have more severe disease, however this was clearly not the case. As previously observed by Offor et al. in malnourished suckling mice Everolimus [36], we found accelerated rotavirus shedding in undernourished mice, however both undernourished and nourished animals were able to clear rotavirus effectively. These later results stand in contrast to findings

by Guerrant and co-workers that report more severe disease and exacerbation of malnutrition when undernourished mice are infected with Cryptosporidium [37], Giardia, [38] and enteroaggregative E. coli [39]. Of note, by choosing to challenge adult mice, our models were better designed to examine rotavirus infection and shedding rather than frank diarrhea—a response limited to EDIM infection of young mice. Additional host factors that might account for Vemurafenib in vivo the divergence of our findings from other published mouse models of malnutrition and gut infection include mouse strain and the method by which undernutrition is induced, e.g., caloric restriction vs. multideficient diets vs. timed separations of pups

from dams. To our knowledge, the “vicious cycle” of diarrhea and undernutrition has not yet been definitively recapitulated in rodent models of viral diarrhea. In addition, the findings of our mouse study parallel results of a large case–control study of diarrhea hospitalizations in Bangladesh, which found that children admitted with rotavirus-positive diarrhea had better Sodium butyrate nutritional status than children admitted for parasitic or bacteria-associated diarrheal illnesses [40]. Another recent mouse study also

found that underweight mice had one less day of diarrhea as compared to their normal-weight and overweight counterparts [41]. The current animal data, together with previously published clinical findings, suggest that undernutrition may indeed be an important risk factor for initial or even repeat rotavirus infections, but that mild-to-moderate malnutrition is not a significant contributor to the severity of rotavirus infections. When nourished and undernourished mice were vaccinated with RRV, we found no group differences in viral clearance following EDIM challenge; however, we did detect group differences in serum and stool antibody responses. Lower levels of total stool IgA in RBD vaccinated mice compared to CD mice might be explained by a deficiency of mucosal IgA production or transport secondary to a delay in maturation of the secretory IgA system due to protein malnutrition, as reported by Green and Heyworth [42]. Our finding of increased serum IgA and IgG in RBD-fed mice is also supported by the work of Neumann et al.
