the mechanism of d-penicillamine induced thrombocytopenia in rheumatoid arthritis was investigated by measuring platelet life-span and platelet production rate in 2 groups of rheumatoid arthritis patients treated with 250-750 mg/day d-penicillamine , 14 with a normal platelet count and 9 with thrombocytopenia ( platelet count 50-130 x 10 ( 9 ) /1 ) .
