Heparinized styrene‐butadiene‐styrene elastomers

Journal of Biomedical Materials Research, 1979
AbstractA heparinized high‐strength elastomer has been developed which is potentially useful as a nonthrombogenic vascular prosthesis. A surface hydroxylated styrene‐butadiene‐styrene (SBS) block copolymer with at least 40% extent of reaction after glow‐discharge cleaning was coated with a 20% acetylated polyvinyl alcohol/heparin mixture containing ...

Cytogenetic effects of styrene and styrene oxide

Mutation Research/Genetic Toxicology, 1978
Styrene and styrene oxide induce various cytogenetic effects, similar in both human lymphocytes in vitro and onion root-tip cells in vivo. Styrene appears to cause chromosome breakage in both systems, and in Allium it shows a strong c-mitotic effect. Styrene oxide, on the other hand, seems to destroy the tertiary folding of the chromatin.

PNEUMOTOXICITY AND HEPATOTOXICITY OF STYRENE AND STYRENE OXIDE

Journal of Toxicology and Environmental Health, 1996
The purpose of this study was to investigate the toxicity of styrene and styrene oxide in the lung in comparison to the toxicity in the liver. Pneumotoxicity caused by styrene or styrene oxide was measured by elevations in the release of gamma-glutamyltranspeptidase (GGT) and lactate dehydrogenase (LDH) into bronchoalveolar lavage fluid (BALF), while ...

Mutagenicity of styrene and styrene oxide

Mutation Research, 1977
Abstract Incubation of S. typhimurium strain TA 1535 with styrene increased the number of his + revertants/plate in presence of a fortified S9 rat-liver fraction. Styrene was also highly cytotoxic for Salmonella cells. Styrene oxide, the presumed first metabolite, had a mutagenic effect towards strains TA 1535 and TA 100 both with and without ...

Toxicity of styrene and styrene oxide on chick embryos

Toxicology, 1977
Styrene and styrene oxide were injected into the air space of fertilized chicken eggs at different times during an incubation period of 14 days. The toxicity of styrene and styrene oxide when injected on the fourth day of incubation revealed an LD50 of 40 mumol/egg and 1.5 mumol/egg, respectively.

Mutagenic effects of styrene and styrene oxide

Mutation Research/Genetic Toxicology, 1979
Abstract Styrene and its presumed metabolite styrene oxide were tested in the Salmonella/liver-microsome test on the tester strains TA1535, TA1537, TA1538, TA98 and TA100 of Salmonella typhimurium . Styrene oxide, in the concentration range 1–10 μmoles per plate, was mutagenic on TA1535 and TA100, both in the absence and the presence of a rat-liver ...
