摘要：The effects of volatile substances inhalation on lactate dehydrogenase and cholinesterase in rats were investigated. Male Sprague-Dawley rats were exposed to marketed odorant,ethyl acetate and ethyl ether for 15 days. Enzyme activities were measured in serum and several tissues such as liver,lung,brain,heart,kidney and muscle to find differences of effects according to the organ. Cholinesterase activity in serum and most of tissues revealed time-dependent decrease in the case of marketed odorant inhalation. Especially in heart and kidney significant decrease was observed. Ethyl acetate exposure to rats revealed also decrease in serum and all tissues by 40% to 60%. Ethyl ether inhalation showed significant decrease by 30% to 50%. Lactate dehydrogenase activity was markedly increased in serum and similarly in heart,brain and kidney by exposure to marketed odorant. No changes were observed in liver. Ethyl acetate exposure to rats revealed increase in serum by about 200%,compared to normal group and in other tissues by 40% to 70% except in liver and muscle. Ethyl ether inhalation showed significant increase in serum by about 100%. There was no change in liver and slight increase in muscle.
