Aflatoxins are potent hepatotoxic and carcinogenic secondary metabolites produced by toxigenic fungi. The present study investigated the protective effect of methanolic leaf extracts of Monanthotaxis caffra (MLEMC) against aflatoxin B1-induced toxicity in male Sprague-Dawley rats. The rats were randomly divided into 6 groups of 8 animals each. Five groups were administered orally for seven days with three different concentrations of MLEMC (100 mg/kg, 200 mg/kg and 300 mg/kg), curcumin (10 mg/kg) or vehicle (25% propylene glycol). The following day, these groups were administered 1 mg/kg b.w. of aflatoxin B1 (AFB1). The experiment was terminated three days after administration of AFB1. Group 6 represented untreated healthy control. Serum aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, creatinine and liver histopathology were evaluated. Methanolic leaf extracts of M. caffra decreased the levels of aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase and creatinine in the sera of rats as compared with the AFB1 intoxicated group. Co-administration of MLEMC improved the histological characteristics of the hepatocytes in contrast to the AFB1 treated group, which had mild to severe hepatocellular injuries including bile duct proliferation, bile duct hyperplasia, lymphoplasmacytic infiltrate and fibrosis. Extracts of M. caffra were beneficial in mitigating the hepatotoxic effects of AFB1 in rats by reducing the levels of liver enzymes and preventing hepatic injury.

Pola Mohammed et al
Diabetes mellitus (DM) is a metabolic disease involving improperly high blood glucose level, hyperlipidemia and hypoinsulinemia. The aim of current study is to assess and compare the influence of Quercus infectoria galls (QIg) extract and glimepiride on pancreatic β-cells secretory function and serum lipid profile in diabetic rats. In the present study, thirty six male rats were used and divided into six groups (n=6), including negative control, STZ induced diabetic control, treated diabetic rats with glimepiride (200mg/Kg Bw), and treated diabetic rats with different concentrations QIg extract, 200 mg, 400 mg and 800 mg/Kg Bw for 42 days, respectively. At the end of the experiment, all rats were fasted overnight, blood samples were collected for measuring fasting blood glucose, insulin hormone and lipid profile. All rats were then scarified by using chloroform in order to take part of the pancreatic tissue. The results show a significant decrease in blood glucose, total cholesterol, triglycerides, low density lipoprotein, very low-density lipoprotein, HbA1c% with obvious elevation in serum insulin hormone and high-density lipoprotein in diabetic rats treated with QIg extract and glimepiride compared with diabetic untreated group. In addition, high atherogenic index in diabetic rats was significantly reduced by different concentrations of QIg extract and glimepiride. Histopathogical results revealed that there was a significant and dose-dependent morphological restoration in the pancreatic structure damages especially at high dose of the extract. These findings provide a new insight into the role of QIg methanolic extract in maintaining normal blood glucose and adequate pancreatic insulin hormone secretion in diabetic rats, amelioration of dyslipidemia and associated cardiovascular alterations with subsequent improvement in pancreatic structural damages in diabetic rats.

Grape seed extraction has many beneficial effects on the cardiovascular system and blood pressure and has also been proven to have anti-obesity effects and/or improve fatty acid oxidation and insulin responses. The objective of this study is to evaluate the effectiveness of grape seed extract on some physiological parameters in multiple systems. To this end, male mice were injected intraperitoneally with (100 mg/kg B.W) for 7 days. Serum was collected to detect the concentration of ALT and TSB (liver functions). Urea and creatinine (a kidney function) concentration was measured. Testosterone, LH, and FSH (male reproductive function) concentration were evaluated. Our results revealed a significant reduction in ALT concentration in the grape seed extraction group compared with the control group. Total serum bilirubin was non-detectable in both the grape seed extraction group as well as the control group. Urea and creatinine concentrations appeared to have no significant change between both grape seed extraction and the control group. Testosterone, LH, and FSH hormone levels were significantly raised in the grape seed extraction group compared with the control group. Prolactin hormone results revealed no change in both the grape seed extraction group and the control group. Our study showed up that grape seed extract can improve male reproductive hormones without any toxic effect on the liver or kidney.

A common characteristic of Mycoplasma diseases is their chronicity, Mycoplasma spp. infection have been frequently associated with upper respiratory infections, chronic lung disease , asthma, meningeal encephalitis, mastitis, arthritis, heart problems, sterility, bone problems , oviduct dysfunctions and death in human and different animal species. In former years, changeable expression of membrane antigens has been detected in a number of Mycoplasma spp., resulting in the assumption that immune prevarication may be an important part of the their infection and pathogenesis. It has been determined how the attachment organelle, which mediates the complicated interactions between various adhesins and auxiliary adhesion proteins to mediate the critical first stage of cytoadherence to respiratory tract epithelium. Additionally, it has been demonstrated that inflammatory cytokines cause tissue damage by intracellular localization, direct cytotoxicity, and activation of the inflammatory cascade via Toll-like receptors (TLRs), and inflammosome activation, which causes air passage inflammation. All of these play crucial roles in the infectious process. This paper seeks to provide a thorough assessment of recent developments in our understanding of Mycoplasma pathogenesis with the understanding of its virulence mechanisms.

Orf which is commonly referred to as contagious ecthyma is a viral infectious disease that infects small ruminants. Little is known about the disease status in our geographical region. This study aimed to determine the seroprevalence of Orf virus in sheep in Basrah province, southern Iraq. Serum samples were randomly collected from 380 sheep of different age and sex groups from 4 different regions in Basrah province, which were Zubair, Abulkhasib, Shatt Al-Arab, and Qurnah. The samples were tested by ELISA for the presence of IgG antibodies to the Orf virus. Out of 380 animals screened, 98 animals were found positive for ELISA, which reveals an overall prevalence of 25.7%. There was no significant difference in the seropositivity between male and female animals. On the other hand, the seropositivity was significantly higher in lambs of the age group 1-6 months in comparison with the other age groups (6-12 months and more than 12 months). This finding indicates that the virus is highly prevalent in Basrah province as confirmed by the ELISA test.
