Protective effect of camel milk as anti-diabetic supplement: biochemical, molecular and immunohistochemical study

Background: Diabetes is a serious disease affects human health. Diabetes in advanced stages is accompanied by general weakness and alteration in fats and carbohydrates metabolism. Recently there are some scientific trends about the usage of camel milk (CM) in the treatment of diabetes and its associated alterations. CM contains vital active particles with insulin like action that cure diabetes and its complications but how these effects occur, still unclear.Materials and Methods: Seventy-five adult male rats of the albino type divided into five equal groups. Group 1 served as a negative control (C). Group 2 was supplemented with camel milk (CM). Diabetes was induced in the remaining groups (3, 4 and 5). Group 3 served as positive diabetic control (D). Group 4 served as diabetic and administered metformin (D+MET). Group 5 served as diabetes and supplemented with camel milk (D+CM). Camel milk was supplemented for two consecutive months. Serum glucose, leptin, insulin, liver, kidney, antioxidants, MDA and lipid profiles were assayed. Tissues from liver and adipose tissues were examined using RT-PCR analysis for the changes in mRNA expression of genes of carbohydrates and lipid metabolism. Pancreas and liver were used for immunohistochemical examination using specific antibodies.Results: Camel milk supplementation ameliorated serum biochemical measurements that altered after diabetes induction. CM supplementation up-regulated mRNA expression of IRS-2, PK, and FASN genes, while down-regulated the expression of CPT-1 to control mRNA expression level. CM did not affect the expression of PEPCK gene. On the other hand, metformin failed to reduce the expression of CPT-1 compared to camel milk administered rats. Immunohistochemical findings revealed that CM administration restored the immunostaining reactivity of insulin and GLUT-4 in the pancreas of diabetic rats.Conclusion: CM administration is of medical importance and helps physicians in the treatment of diabetes mellitus.Keywords: Camel milk, Diabetes, Gene expression, Immunohistochemistr

INSULIN-MIMETIC ACTIVITY OF STEVIOSIDE ON DIABETIC RATS: BIOCHEMICAL, MOLECULAR AND HISTOPATHOLOGICAL STUDY

Background: Stevioside has been used as a medication for reducing glucose levels in diabetic patients. The exact mode of action is still unclear. Therefore, the current study outlines the molecular and biological roles of stevioside in treatment of diabetes. Materials and Methods: induced diabetic male wistar rats treated with stivioside and metformin as therapy for diabetic rats. Biochemical, molecular and histopathological studies have been done to evaluate the therapeutic effect of stevioside on minimizing levels of glucose in diabetic rats. Results: Stevioside administration normalized kidney and liver biomarkers, restored alterations in antioxidants activity and lipid profiles. Moreover, stevioside increased insulin and leptin secretion that are decreased in diabetic rats to the normal levels.For mRNA expression, stevioside up-regulated the expressions of PK and IRS-1 genes which are down-regulated in diabetic rats, and was very effective in down-regulation of CPT-1 mRNA expression. At the cellular levels; stevioside normalized the histopathological changes induced in pancreas. Conclusion: Stevioside has insulin like effects and it is useful for diabetic patient’s therapy

Ameliorative Effect of <i>Bacillus subtilis</i> on Growth Performance and Intestinal Architecture in Broiler Infected with Salmonella

A total of 600 day-old broiler chicks (Ross 308) confirmed for the absence of Salmonella were randomly allocated to five treatments each with 10 replicates: negative control (basal diet only); positive control (basal diet) + infected with Salmonella; T1, Salmonella infected + avilamycin; T2, Salmonella infected + Bacillus subtilis (ATCC PTA-6737; 2 &#215; 107 CFU/g) and T3, Salmonella infected + B. subtilis (DSM 172999; 1.2 &#215; 106 CFU/g). The results revealed that feed intake (FI) and body weight (BW) were significantly (p &lt; 0.01) lower in T1 compared to T2. The feed conversion ratio (FCR) was significantly (p &lt; 0.01) lower in T2 and T3 compared to other treatments. Similarly, the performance efficiency factor (PEF) was also significantly (p &lt; 0.01) higher in T2 and T3 compared to positive control. Villus height was significantly (p &lt; 0.01) higher in T2 compared to all other treatments. However, villus width and surface area were significantly (p &lt; 0.01) higher in T1. In conclusion, dietary supplementation with B. subtilis improved growth and intestinal health by reversing the negative effects of Salmonellosis

Sustained Functioning Impairments and Oxidative Stress with Neurobehavioral Dysfunction Associated with Oral Nicotine Exposure in the Brain of a Murine Model of Ehrlich Ascites Carcinoma: Modifying the Antioxidant Role of <i>Chlorella vulgaris</i>

Background: This study provides a model for studying the mechanism(s) responsible for the nervous tissue damage and misfunctioning that occurred due to oral nicotine exposure, considered a stress factor, during the presence of Ehrlich ascites carcinoma bearing in the mouse model (EAC). The mitigating role of Chlorella vulgaris (CV) against nicotine-induced brain damage was evaluated. Methods: Eighty Swiss female mice were classified into four groups, these were the control, the CV group, the nicotine group(100 µg/kg), and the combination group. Oxidant/antioxidant status, proinflammatory cytokines levels, DNA damage, quantitative microscopical lesions, and Caspase 3, Bcl-2 proteins were assessed in the current study. Levels of dopamine (DA) and gamma-aminobutyric acid (GABA) were also evaluated. Results: Nicotine was found to cause pronounced neurobehavioral alterations, increase the mortalities oxidative stress DNA damage, and augment the inflammatory response in brain tissue alongside the microstructural alteration. The administration of CV with nicotine in EAC-bearing mice rescued the detrimental effects of nicotine. Conclusions: CV aids in reducing the harmful effects of nicotine and returns the conditions caused by nicotine to near-control levels. Thus, we are in favor of giving it to cancer patients who are taking daily dosages of nicotine even by smoking cigarettes or being exposed to second-hand smoke
