Abstract A severe outbreak of Infectious Bursal Disease (IBD) recorded in (30) chicken flocks at different districts in Sharqia Governorate during 2019 that showed high mortalities (30%) and severe immunosuppression. Attempts to control (IBD) by antiviral iron oxide chitosan nanocomposite (characterized nano-size 35.1±5 nm with a stable state, zeta potentials16.8 ± 10.9, the PDI. 0.91 and iron concentration in nanocomposite is 2625 mg/L,).Eighty Baladi broiler chicks at the age of 21 days were divided into 4 groups. Group A (as the negative control group), group B (as the positive control group), group C (as the nanocomposite treatment group), and group D (only received nanocomposite). The used treatment was iron oxide chitosan nanocomposite with the concentration of (1 mg/ 100ml) IC50 orally administered for 3 days post infection.The virus shedding showed marked significant decrease (P<0.05) in group C compared to group B was 0.5 to 1 log 10 compared to group B was 3 to 6.4 log 10.Histopathological lesions of bursa, spleen, thymus, liver, and kidney in group C after 6 days PI showed hyper activity of lymphoid population compared to chicks infected group which revealed necrosis and depletion of lymphoid elements of the bursa, thymus, and spleen with blood vessels had marked congestion and hemorrhages in parenchyma.Base on this study, iron oxide chitosan nanocomposite showed an antiviral activity that could significantly reduce viral shedding, and could decrease pathological changes in lymphoid organs which is considered to be better protection for solving health problems in infected chicks.

A total of 75 day old broiler chicks were divided into three equal groups. Group A served as negative control. Group B (positive control) and C (treatment group) were intoxicated with oral administration of CCl4 @ 1 ml/kg body weight after every 3rd day during 15-28 days of age. Group C was given AV/LCP/18 @ 0.10 ml / chick / day in drinking water during 29th-42nd day of age. At the end of experiment, significantly (P is less than 0.01) higher mean body weight and lower FCR was observed in treatment group C as compared to positive control group B. Similarly, significantly (P is less than 0.05) decreased levels of SGOT, SGPT, cholesterol, triglycerides, creatinine and higher mean values of serum protein profile along with mild degenerative changes in liver and kidney of broilers in group C were observed as compared to group B indicating therapeutic efficacy of AV/LCP/18 in ameliorating the toxic effects or FLKS induced by CCl4 in commercial broilers

Vaccination is used as a control and prevention tool for infectious bursal disease (IBDV) in poultry. A new strategy for improving vaccination efficiency is the use of in-feed immune modulating ingredients. The aim of this study was to test if the use of beta-(1,3)-glucans in feed can enhance IBDV vaccination. The trial was conducted in ROSS 308 broilers. In the study, a negative control group (not vaccinated, not supplemented), a positive control group (vaccinated, not supplemented) and a treated group (vaccinated, supplemented with beta-(1,3)-glucan) were included. All broilers, except the negative control, were orally vaccinated at 18 days of age with a live IBDV vaccine. Blood samples were taken at day 18 and 35 to measure antibody titers against IBDV. Serological analysis showed the presence of maternal derived antibodies at time of vaccination in some birds. The beta-(1,3)-glucan supplemented birds showed decreased CV% (coefficient of variation) and significantly increased average antibody titers compared to non-supplemented vaccinated birds. Additionally, the beta-(1,3)-glucan group showed increased number of birds with antibody titers above the titer threshold for protective immunity. The results obtained in the current trial clearly indicate that beta-(1,3)-glucan can increase seroconversion and serological response to IBDV vaccination.

Abstract Objective To investigate the impact of microecological preparation combined with modified low-carbon diet on the glucolipid metabolism and cardiovascular complication in obese patients. Methods From August 2017 to July 2020, 66 obese patients were recruited, and administrated with an modified low-carbon diet with (group A) or without (Group B) microecology preparation and a balanced diet in control group (group C) for 6 months. Meanwhile, 20 volunteers administrated with a balanced diet were recruited as the healthy control group (group D). Results After 6-month intervention, obese subjects in group A and B showed significant improvement of body and liver fat mass, reduction of serum lipid levels, intestinal barrier function markers, insulin resistance index (IRI), high blood pressure (HBP) and carotid intima thickness, as compared with subjects in group C. More importantly, subjects in group A had better improvement of vascular endothelial elasticity and intimal thickness than subjects in group B. However, these intervention had no effect on carotid atherosclerotic plaque. Conclusion Administration of microecological preparation combined with modified low-carbon diet had better improvement of intestinal barrier function, glucose and lipid metabolism, and cardiovascular complications than low-carbon diet in obese patients, but the effect of a simple low-carb diet on carotid atherosclerotic plaque need to be further addressed.

AbstractIntroduction:Laryngopharyngeal reflux is increasingly being implicated in several otolaryngological disorders.Aims:To study a potential correlation between pre-operative laryngopharyngeal reflux and wound healing and recovery after tonsillectomy, based on subjective and objective findings.Materials and methods:A prospective, blinded study was undertaken, including 60 patients scheduled for tonsillectomy, divided into two equal groups: a study group (group A) with pre-operative laryngopharyngeal reflux documented using ambulatory 24-hour pH monitoring; and a control group (group B) without laryngopharyngeal reflux.Results:Group A had significantly higher pain scores on the seventh and 14th post-operative days (p = 0.022 and p = 0.000, respectively) and took a significantly longer time to return to normal eating (p = 0.013), compared with group B. Group A also showed significantly slower healing on the seventh and 14th post-operative days, as estimated by assessing the grade of post-operative slough formation (p = 0.016 and p = 0.029, respectively). A significant correlation between the number of pharyngeal reflux episodes and the degree of post-operative slough was also found.Conclusions:Laryngopharyngeal reflux can significantly decrease wound healing following tonsillectomy. Therefore, pre-operative recognition and management of this condition is desirable in order to eliminate its negative post-operative effect.

AIM: To investigate the protective effect of human umbilical cord mesenchymal stem cells (hUCMSCs) modified by the LIF gene on the retinal function of diabetic model rats and preliminarily explore the possible mechanism. METHODS: A stably transfected cell line of hUCMSCs overexpressing leukemia inhibitory factor (LIF) was constructed. Overexpression was verified by fluorescent quantitative polymerase chain reaction (qPCR). Forty-eight adult Sprague-Dawley rats were randomly divided into a normal control group (group A), streptozotocin-induced diabetic control group (group B), diabetic rats at 3mo injected with empty vector-transfected hUCMSCs (group C) or injected with LIF-hUCMSCs (group D). Four weeks after the intravitreal injection, analyses in all groups included retinal function using flash electroretinogram (F-ERG), retinal blood vessel examination of retinal flat mounts perfused with fluorescein isothiocyanate-dextran (FITC-dextran), and retinal structure examination of sections using hematoxylin and eosin staining. Expression levels of adiponectin (APN), high-sensitivity C-reactive protein (hs-CRP), and neurotrophin-4 (NT-4) in each group was detected using immunohistochemistry, PCR, Western blotting, and ELISA, respectively. RESULTS: A stable transgenic cell line of LIF-hUCMSCs was constructed. F-ERG and FITC-dextran examinations revealed no abnormalities of retinal structure and function in group A, severe damage of the retinal blood vessels and function in group B, and improved retinal structure and function in group C and especially group D. qPCR, ELISA, and Western blot analyses revealed progressively higher APN and NT-4 expression levels in groups B, C, and D than in group A. hs-CRP expression was significantly higher in group B than in groups A, C, and D, and was significantly higher in group C than in group D (P<0.05). CONCLUSION: LIF-hUCMSCs protect the retina of diabetic rats by upregulating APN and NT-4 expression and downregulating hs-CRP expression in the retina.

Abstract: Cayenne pepper (Capsicum frustescens L ) is commonly in daily food. This study aimed to determine the effect of cayenne pepper to histopathological changes in gaster of Wistar rats induced by aspirin. This was an experimental study. Subjects were Wistar rats consisted of 5 rats as the negative control and 20 rats as the treatment group. Group A, the negative control group, was untreated; group B was treated with aspirin 21mg/day for 10 days; group C was treated with aspirin 21mg/day for 10 days together with cayenne pepper 84mg once daily; group D was treated with aspirin 21mg/day for 10 days followed by cayenne 84mg twice daily; and group E was treated with aspirin 21mg/day for 10 days and then was untreated for 3 days. The histopathological changes in group C showed a lot of inflammatory cells and erosion of gastric mucosa epithelium compared to group B, D, and E. Group D also showed inflammatory cells but no erosion as in group C. Group E had less inflammatory cells than group B, C, and D. Conclusion: Administration of aspirin 21mg/kg BW for 10 days led to acute gastritis in Wistar rat. Administration of aspirin together with cayenne 84mg/day led to acute gastritis and erosion of gastric mucosa epithelium. However, administration of cayenne pepper 168mg/day after aspirin led to acute gastritis without erosionKeywords: pepper, gaster, aspirinAbstrak : Cabe Rawit (Capsicum frustescens L.) banyak dijumpai dalam makanan sehari-hari.

PURPOSE: To evaluate axonal regeneration after end-to-side nerve repair with fibrin glue in rats. METHODS: Forty-five Wistar rats were divided into three groups: group A (n=15), were not submitted to surgery (control group); group B (n=15) were submitted to fibular transection without repair; and group C (n=15), were submitted to fibular transection with end-to-side nerve anastomosis using fibrin glue, in the lateral surface of an intact tibial nerve. The three groups were submitted to walking track (30 and 90 days) and posterior morphometrical analysis (90 days). RESULTS: The functional tests demonstrated that there was no difference in the walking track during the study in group A (p>0.05). The group B had walking pattern impairment in the two tests (p>0.05). The group C had walking pattern impairment in the first test, with important recovery in the second test (p<0.05). The morphometrical assessment revealed significantly higher number of regenerated mielinates axons in group C, compared to group B (p<0.05). CONCLUSION: The end-to-side nerve repair with fibrin glue shows axonal recovery, demonstrated through functional and morphometrical ways in rats.

Five groups of genetically susceptible chickens were inoculated at hatching with lymphoid leukosis virus; four of these were given infectious bursal viruses of varying virulence at 14 days of age and one group was not inoculated (control). All chickens in the control group developed evidence of lymphoid leukosis by 180 days. Two groups given relatively virulent bursal disease viruses, which destroyed bursal lymphoid cells, did not develop lymphoid leukosis. Treatment with avirulent vaccines had no visible effect on bursal morphology and did not significantly alter the incidence of lymphoid leukosis in two other groups, although the lime of development was delayed. Results of our study show that viral-induced destruction of the bursa of Fabricius eliminates the development of lymphoid leukosis but that infection without bursal destruction has little effect on lymphoid leukosis.

The effects of three dissolving agents on the accuracy of an electronic apex locator- (EAL-) integrated endodontic handpiece during retreatment procedures were evaluated. The true lengths (TLs) of 56 extracted incisor teeth were determined visually. Twenty teeth were filled with gutta-percha and a resin-based sealer (group A), 20 with gutta-percha and a zinc oxide/eugenol-based sealer (group B), and 16 roots were used as the control group (group C). All roots were prepared to TL. Guttasolv, Resosolv, and Endosolv E were used as the dissolving solutions. Two evaluations of the handpiece were performed: the apical accuracy during the auto reverse function (ARL) and the apex locator function (EL) alone. The ARL function of the handpiece gave acceptable results. There were significant differences between the EL mode measurements and the TL (P<0.05). In these comparisons, Tri Auto ZX EL mode measurements were significantly shorter than those of the TL.
