Acute cholecystitis and persistent liver necrosis in mice provoked by isothiocyanate.
Two known cholangiotoxic agents, alpha-naphthylisothiocyanate (ANIT) and p-phenylenediisothiocyanate (PDT), were administered in single doses to mice to study their effects on the gallbladder. Both compounds caused maximal bile duct necrosis and periportal hepatocytic necrosis at 24 hours. In contrast, the gallbladders were edematous but not necrotic at 24 hours after treatment. At 48 hours, and in some animals up to four days, severe cholecystitis was present, while bile ducts revealed progressive regeneration. The delay in the onset of gallbladder lesions was assumed to be the result of the toxic agent concentration in gallbladder bile after hepatic bile secretion was suppressed for 24 hours. The lesions provoked by PDT were similar to those induced by ANIT, except for a hemorrhagic component.
