Additional evidence for thiram-induced liver toxicity is provided by the observation that there was approximately 50% inhibition of the activity of hepatic microsomal benzphetamine N-demethylase with a concomitant decrease in the concentration of cytochrome P-450, an important component of the mixed-function oxidase system.

In rats, a single oral dose of 30 mg or 1 g thiram per kilogram produced a significant prolongation of the hexobarbital sleeping time or zoxazolamine paralysis time, respectively, a depression of hepatic microsomal O-demethylation of p-nitroanisole to p-nitrophenol, and a decrease in the microsomal cytochrome P-450 content.

The 1/4 LD50 dose of thiram decreased the cytochrome P-450 content below the control level (69.62%) in 0.75 h and the same dose of MIC could decrease the cytochrome P-450 level by 40% compared to the control after 3 days of consecutive injection.

Furthermore, measurement of the activities of hepatic microsomal and serum enzymes at 5 hrs and 24 hrs following thiram treatment indicated that thiram caused significant loss of cytochrome P-450 and benzphetamine N-demethylase activity only at 24 hrs interval whereas there was significant elevation of sorbitol dehydrogenase (SDH) and serum glutamic oxalacetic transaminase (SGOT) activity at 5 and 24 hrs after treatment.

We studied induction of the CYP 1A or CYP 2B monooxygenases in rat liver by the fungicides: thiram, captan, captafol, dodine and the drugs: nitrofurazone, furazolidone and the plant flavonoid: quercetin.

In both experiments, six rats/group were fed diets based on the AIN-93M diet (Control) or the same modified to contain either 500 mg calcium (Low Ca), 7 mg Zn (Low Zn): 2 mg copper (Low Cu), 60 mg zinc (High Zn) or 12 mg copper (High Cu) in the following combination: Control, LCa/LZn, LCa/LZn/LCu, or HZn/HCu, with and without a pesticide mixture containing acephate, endosulfan, and thiram at 25% LD50 for four or two weeks.

The dithiocarbamates (DTCs) disulfiram, thiram, diethyldithiocarbamate and dimethyldithiocarbamate on the equimolar base inhibited to the same extent both the lipid peroxidation (LPO) induced by ascorbic acid (non-enzymatic) and that stimulated by an NADPH-regenerating system with CCl4 admixture (enzymatic).
In parallel with the inhibition of MDA formation, oxidative destruction of microsomal cytochrome P-450 was delayed with increasing concentrations of the DTCs.

A further enhancement of the oxygen radical content of the cells by adding microsomes that produce oxygen radicals via autoxidation of cytochrome P-450 is proposed as the mechanism for the 'metabolic activation of TMTD '.
