Chemical and biochemical studies on rapeseed oil [Giza 1, locally produced]

Physical and chemical characteristics of stored rapeseed oil [Giza 1, locally produced] were compared with the fresh oil. The oil was free form long chain fatty acids [> 18]. Due to storage there was highly significant increase in acid value and some of C 18 was converted into shorter fatty acids

Chemical and biochemical studies on rapeseed oil, 2-hepato-renal function as influenced by feeding rapeseed oil

Rapeseed oil was incorporated into standard diets and fed to weanling rats for 45 days. The animals grew normal and there was no sign of abnormality or toxicity. The nutritive value of rapeseed oil was enhanced when it was mixed with cottonseed oil [1:1]. The results showed no change in serum lipid pattern or liver function

Changes in rat metabolism after simultaneous inhalation of carbamate and of insecticides

Inhalation of the aerosol of the commercial formulation Baygon [public health insecticide] for a period of 4 weeks caused a marked reduction in the activities of hepatic ALP and aminotransferases due to increased permeability of these enzymes from liver cells. Continuous inhalation of Baygon and simultaneous inhalation of Baygon and Vapona raised the level of blood glucose and blood urea while the activity of erythrocytes AChE was markedly suppressed. The administration of the antidote atropine sulfate decreased the cholinergic effect of these insecticides. The fatty acid composition of rat liver by GLCindicated that the unsaturated fatty acids [C18:1 and C18:2] were markedly decreased while short chain fatty acids were markedly increased

Preparation and evaluation of the biological activity of some acetanilide derivatives

A number of acetanilide derivatives including 2-, 3-, 4- nitro and 4- chloroacetanilide were prepared by refluxing acetic anhydride in presence of glacial acetic acid and zinc with the corresponding aniline derivative. 4-chloro-chloroacetanilide and 3, 5-dinitroacetanilide were synthesized by direct chlorination or nitration of the corresponding anilide, respectively. The compounds were identified by elementary analysis and spectral studies. These compounds have been tested for their molluscicidal activities against fresh water snails [Australorbis glabratus] and some of them have been evaluated for their toxicities against albino rats. 4-chlorochloroacet-anilide was the most promising compound due to its potent molluscicidal activity and low mammalian toxicity
