[Liver regeneration after major hepatectomy, evaluation of dogs hepatectomy]

The aim of our study is to evaluate anatomic regeneration and metabolic derangement of the liver after major resection in dogs This is an experimental study on 9 dogs; we divided the dogs in two groups: the first group [5 dogs] underwent at one go major hepatectomy [90% of the liver].The second group [4 dogs] underwent successively a resection of 75% of the liver and a second resection of 90% of the restored liver six months later. All dogs underwent a metabolic and morphologic studies of the liver and of their kidney function In the first group; all dogs which underwent 90% hepatic resection died 48 hours after the surgical resection of hepatic insufficiency. The ultra microscopic study shoud the role of portal hypertension in hepatic degeneration on the first group. In the second group, the dogs survived the first resection, and our study shows a regeneration of the liver after resection and sub normal hepatic function The liver is able to regenerate after minimall resection but major resection must be done by successively resection to avoid hepatic dysfunction, but the time between resection must be evaluate later

In order to locate the rate of positivity of the different markers of hepatitis that can be transmitted through blood [Ag HBs, anti- HBc Ab, anti- HCV Ab and transaminases [ALAT], we have conducted a study over 300 blood donors and who are sale, equally shared between the parts of age and of sex. The ALAT were superior to the normalcy in 10.66% of the cases, the male sex being 3 times more affected than that of the female. The Ag HBs was positive in 4.66% of the cases. The male sex is twice as affected as the female sex. One of three persons who donated blood [37.33%] had anti- HBc Ab. Finally none of the 300 blood donors has the anti-HCV Ab. There 's a very weak recovering between the presence of Ag HBs and of ALAT superior to the normalcy, a weak recovering between Ag HBs and anti- HBc Ab and a certain recovering between ALAT superior to the normalcy and the pr‚sence of anti- HBc Ab. There is no recovering between the anti HCV Ab and the indirect markers. Eventually, the systematization of all these tests over each donation engenders the elimination of more than 2/5 of the collected products
