Studies on internal parasites of cattle egret and its role in the environmental pollution in some areas in Alexandria and Behera governorates

A total of 35 cattle egret were collected from different locations in Alexandria and Behera Governorates, were captured alive. These birds are subjected fro parasitological examination. Parasitological investigation revealed that eight species of parasites were identified. The infestation f Trematodes were Apharyngostrigea ibis [74.3%] Apatemon gracilis [37.1%] nephrostomum ramosum [25.7%] and, Heterophyes equalis [17.1%]. Nematodes were, Synhimantus invaginatus [94.3%] Porrocaecum wu [14.2%] and, Heterocheilus species [5.7%] while Acanthocephala was, Centrorhynchus conspectus [2.8%]. The public health importance of these results were discussed

Role of vitamin E in dietary iron overload in rats

The effect of chronic dietary iron overload on various organs of adult male and female rats was studied and compared with concomitant administration of vitamin E, 2 hours before iron. 60 mature rats of both sexes were used and divided into equal 5 groups. The first group received control diet.The second group received corn oil. Ferrous iron [100 mg/kg/day] was given orally to group III. Vitamin E [10 gm/kg/day] was given orally either separate [group IV] or 2 hours before iron supplementation. After 6 weeks serum and organs iron were estimated together with serum GOT, GPT, acid and alkaline phosphates and total lipids. Furthermore histopathological and histochemical study of iron storage were carried out in liver, spleen, lymph nodes, bone marrow, stomach and intestine. Iron overload induced marked rise of iron in serum with histochemical demonstration of its granules in liver, spleen, abdominal lymph nodes, bone marrow, stomach and intestine, associated by elevation in serum GOT, GPT, acid and alkaline phosphatases with reduction in total serum lipids.These pathological and biochemical changes were more evident in male rats than females. They were on the other hand, markedly improved by presupplementation with vitamin E. However, the resulting improvement was still significantly higher than the controls which issues our recommendation for further study using larger doses of vitamin E

Histochemical changes in the liver of mice after Stadol administration with special reference to liver function tests

Eighteen mature mice were used and divided into three groups: [1] The 1st group [6 animals] was kept as control. [2] The 2nd group [6 animals] was given daily S.G. doses of stadol for 2 weeks. [3] The 3 rd group [6 animals] was given daily S.G. doses of stadol for 4 weeks. After each period blood samples were collected to test the liver functions. Then the animals were scarificed and their livers were removed and frozen sections were prepared for histochemical study of five enzymes. The significance of the results was discussed. Generally there is increased activity of the hydrolytic enzymes differ. The affection was more severe with prolongation of the period of administration of stadol. Liver functions must be normal before administration
