title: Hepatoprotective effects of prostacyclins on CCl4-induced liver injury in rats.
abstract: Certain biochemical parameters of acute liver injury induced by carbon tetrachloride were investigated in rats treated with prostacyclin (PGI2) and two of its derivatives. Serum glutamate oxalacetate transaminase elevation and both triglyceride accumulation and reduction of glycogen content in liver were significantly suppressed by PGI2, 7-oxo-PGI2, and 20-methyl-13,14-didehydro-2,4-m-interphenylene-PGI2 48 hr after the injury. Prostacyclins partially restored some of the parameters of injury even in doses of 10 micrograms/kg ip. When the compounds were given 24 hr after CCl4 intoxication, much more pronounced protection was observed than in the case of treatments 1 hr before administration of the hepatotoxin. Thus, all tested prostacyclins exerted significant protective effects on acute liver damage which is obtained mainly in the second phase of the injury.
