improved safety of splenoportography by plugging of the needle tract.splenoportography, a useful preoperative diagnostic procedure in patients with portal hypertension, has been largely discontinued because of the risk of hemorrhage. we have used both ivalon and gelfoam in particle and plug form to plug the needle tract after splenoportography. initial studies were conducted on six dogs. plugging of the needle tract by injection of suspensions of small gelfoam or ivalon particles resulted in intravasation of these particles into the splenic vein. this was demonst ...197898987
comparison of the genetic activity of 5-nitroimidazole derivatives in escherichia coli, neurospora crassa, saccharomyces cerevisiae and drosophila melanogaster.5-nitroimidazoles, including metronidazole (compound 1) and 3 analogues (compounds 2, 3 and 4) of actual or potential chemotherapeutic use were assayed for genetic activity in test systems detecting forward and back mutations in escherichia coli k-12/343/113, forward mutations in neurospora crassa heterokaryon 12, mitotic gene conversion in the heteroallelic diploid yeast strain saccharomyces cerevisiae d4 and sex-linked recessive lethals in drosophila melanogaster. whereas metronidazole exhibit ...1979154545
isolation and partial characterization of an amphiphilic 56-kda fatty acid binding protein from rat renal basolateral membrane.we have identified a 56-kda fatty acid binding protein in rat renal basolateral membrane and purified it by extraction in nonionic detergent (triton x-100), followed by gel filtration, deae-cellulose chromatography, and affinity chromatography. the purified protein was homogeneous on polyacrylamide gel electrophoresis in the presence of triton x-100 or sds. it showed amphiphilic properties on gel filtration, polyacrylamide gel electrophoresis, and oleate-sepharose 4b chromatography. its molecula ...19873597346
