Ground-glass hepatocytes resembling those seen in HBsAg carriers on hematoxylin and eosin and on trichrome stained sections, but giving a negative reaction to orcein and a positive one to PAS, were found in liver biopsy specimens from nine asymptomatic former alcoholics who were on treatment with cyanamide, in one of four who had been treated with cyanamide several months before the liver biopsy procedure, in none of 15 treated with disulfiram, and in one of eight who had apparently not received aversive drugs. Portal and periportal inflammatory changes and fibrosis were more frequently observed in biopsy specimens containing PAS-positive ground-glass hepatocytes than in those without, but cirrhosis was found with a similar frequency. It is concluded that periportal PAS-positive ground-glass hepatocytes are a histological marker of cyanamide treatment.

D003484 Cyanamide A cyanide compound which has been used as a fertilizer, defoliant and in many manufacturing processes. It often occurs as the calcium salt, sometimes also referred to as cyanamide.

D003486 Cyanides Inorganic salts of HYDROGEN CYANIDE containing the -CN radical. The concept also includes isocyanides. It is distinguished from NITRILES, which denotes organic compounds containing the -CN radical. Cyanide,Isocyanide,Isocyanides
D004221 Disulfiram A carbamate derivative used as an alcohol deterrent. It is a relatively nontoxic substance when administered alone, but markedly alters the intermediary metabolism of alcohol. When alcohol is ingested after administration of disulfiram, blood acetaldehyde concentrations are increased, followed by flushing, systemic vasodilation, respiratory difficulties, nausea, hypotension, and other symptoms (acetaldehyde syndrome). It acts by inhibiting aldehyde dehydrogenase.
