Dantrolene sodium(DS) is a long acting skeletal muscle relaxant which has been successfully used to control muscle spasticity in patients with various neurological disorders. However, its use is associated with hepatotoxicity. Tissue sulfhydryl group has many important roles for cellular integration and glutathione serves as a substrate for the detoxification metabolism. The purpose of this study were to investigate the effect of DS on tissue sulfhydrl group and glutathione content. Foully albino rats were divided into two groups ; saline treated (control) and DS treated groups. DS dissolved in saline was administered orally. All rats were sacrificed after 7. 14. 21 and 28 days of DS ana saline treatment by dacapitation ana liver was removed for the enzyme preparation. Total and nonprotein sulfhydryl were measured by the method of Sedlak and Lindsay (1968). Total glutathione content was assayed according to the method described by Tietze (1969) and glutathione reductase was assayed according to the method of Racker (1955), The results obtained are summarized as follows : DS administration significantly depressed the total, protein and nonprotein sulfhydryl content in liver. There were significant reduction of both total glutathione content and glutathione reductase activity in liver. On the basis of the above results it may be speculated that the toxicity of DS are well correlated with tissue sulfhydryl content and glutathione reductase activity.
