These deaths were due primarily to injury to the stomach and intestine, but there war-' secondary effects on the lungs, brain, and pancreas, post-mortem autoiysis partially obscured the. effects: of the chemical in these four -instances. The principle change was in the liver which shoved morphological deviations and weight changes. The 12 mg/kg dose level appears to be the transition d^ne for this effect. HLAB000241 The chemical also produced changes in the kidneys down bo th;s * 0 * 12 mg/kg level, which were accompanied by an increase in weight ab snu higher. ..

Regenerating end Degenerating Liver Procedure; Regenerating liver tissue was induced by partial hepetectpmy C<O~?0$) in six male rats from the stock colony. Forty-eight hours after the operation a single oral dose of AHT* equivalent to 12 mg/kg body weight was administered by intubation. Fourteen days later ths animals were sacrificed, the livers removed* weighed and analysed. The experiment was repeated a second tine* reversing the procedure by performing the partial hepateciomy forty-eight hours after ths dose of AKT had been administered. Degenerating liver tissue was induced chemically by administering* intraperitooeally* A,1 ml of carbon tetrachloride per 100 gm of body weight to rats h 8 hours after intubating them with 12 mg/kg of 1HT, Abimale-which received only carbon tetrachloride served as controls.
