[Effects of green tea extract on experimentally induced toxicosis of carrageenan in male albino rats]

Green tea extract [GTE] is rich in polyphenolic compounds whose antioxidant activity is several fold higher than that of vitamins C and E. In the present study, the effect of GTE on the carrageenan toxicosis in male albino rats using intra-articular injection of 0.1 ml of carrageenan solution was investigated. Three groups of 10 rats each were used: Control, Carrageenan alone, and carrageenan plus GTE. After one week of treatment, the plasma levels of lipid -peroxides and nitric oxide as well as total thiol were measured. The histopathological examination of the liver, spleen and kidneys of the three groups were performed .Animals treated with carrageenan alone showed significant increase value in the levels of both lipid peroxides and nitric oxide in comparison to the control group. In rats that received GTE, the changes in plasma levels of lipid peroxides and nitric oxide were not statistically present from the control group, while the total thiol levels in the GTE group were significantly increased [p<0.05] in comparison with carrageenan only and control groups

Virological and pathological studies on avian encephalomyelitis among young chicks at El-Qassiem Area, Saudi Arabia

A history of nervous disturbances and moralities [25%] among young chickens 10-21 day of age as well as a temporary drop in egg production and hatchability [10%] in parent flock occurred in a large poultry farm at EL-Qassiem area, kingdom of Saudi Arabia. Detection, isolation and identification of avian encephalomyelitis [AE] virus was done using embryonated chicken eggs, immunoflourscence [IF] and Immunodiffusion [ID] tests. Serological investigations were carried out on infected sera from both parent flocks and broiler chicks using Enzyme-linked immunosorbant assay [ELISA]. Histopathological studies were carried out on samples from naturally infected chick brains as well as brains from inoculated hatched chicks
