VP 16-213 (etoposide, abbr. to VP), an oncostatic drug, was administered orally to Crj : CD (Sprague-Dawley) rats of both sexes at dose levels of 3, 10, 30 and 100 mg/kg/day for one month with the object of examining its subacute toxicity and the reversibility of toxic effects. The summarized results obtained are as follows: VP 30 mg/kg suppressed body weight increase and feed intake, and brought soft stool. VP 100 mg/kg decreased body weight and feed intake, and induced diarrhea, depilation and so forth. Furthermore, half of the animals at this dose level died showing systemic debility and emaciation. VP 30 and 100 mg/kg predominantly decreased red blood cell count as well as white blood cell count accompanied with lowered lymphocyte fraction. VP 10 mg/kg and higher lowered total serum protein content and serum alkaline phosphatase activity, and elevated A/G ratio. VP 10 mg/kg and higher caused thymic atrophy and a decrease in testicular weight; 30 and 100 mg/kg brought suppression of spermatogenesis; and 100 mg/kg predominantly induced appearance of giant cells in epididymis, hypoplasia of bone marrow, ileocecitis, and atrophy of prostate, seminal vesicle and splenic germinal centers. Above-described changes excluding exacerbation of the findings on testis and epididymis were shown to be generally reversible. Based on these results, the no-effect dose level of VP under the present experimental condition was estimated to be 3 mg/kg/day against rats of both sexes.

VP 16-213 (etoposide, abbr. to VP), an oncostatic drug, was administered orally to Crj : CD (Sprague-Dawley) rats of both sexes at dose levels of 1, 3, 10 and 30 mg/kg/day for six months with the object of examining its chronic toxicity and the reversibility of toxic effects. The summarized results obtained are as follows: VP 30 mg/kg suppressed body weight increase and feed intake, and brought transient diarrhea, anemia and depilation. Some animals receiving this dose died showing systemic debility, emaciation and ataxia. VP 3 mg/kg and higher predominantly decreased red blood cell count as well as white blood cell count accompanied with lowered lymphocyte fraction. VP 30 mg/kg lowered total serum protein content and elevated A/G ratio in males, and lowered serum alkaline phosphatase activity in females. VP 10 and 30 mg/kg predominantly induced thymic atrophy, testicular atrophy with suppression of spermatogenesis and tubular atrophy, a decrease in epididymal weight, and splenic erythropoiesis. Above-described changes excluding the findings on testis and epididymis in VP 30 mg/kg group were shown to be generally reversible. Based on these results, the non-effect dose level of VP under the present experimental condition was estimated to be 1 mg/kg/day against rats of both sexes.

VP 16-213 (etoposide, abbr. to VP), an oncostatic drug, was administered intravenously to Crj : CD (Sprague-Dawley) rats of both sexes at dose levels of 0.15, 0.50, 1.5 and 4.5 mg/kg/day for one month with the object of examining its subacute toxicity and the reversibility of toxic effects. For the purpose of comparison, vincristine (abbr. to VCR) was administered in the same manner at dose levels of 0.04 and 0.08 mg/kg/day. The summarized results obtained are as follows: VP 0.50 mg/kg and higher suppressed body weight increase and food intake dose-responsively. VP 4.5 mg/kg brought depilation and anemia, and some of male animals receiving this dose died showing systemic debility, emaciation and ataxia. VP 0.50 mg/kg and higher decreased white blood cell count accompanied with lowered lymphocyte fraction, and 1.5 and 4.5 mg/kg predominantly decreased red blood cell count. VP 1.5 and 4.5 mg/kg lowered total serum protein content and serum alkaline phosphatase activity, and elevated A/G ratio. VP 0.50 mg/kg and higher predominantly decreased testicular weight, and 1.5 and 4.5 mg/kg predominantly brought thymic atrophy, hypoplasia of bone marrow and testicular atrophy with suppression of spermatogenesis and tubular atrophy. VP 4.5 mg/kg induced atrophy of germinal centers and hemosiderosis in spleen, and epididymal atrophy with decrease of sperms in number and appearance of giant cells. Above-described changes excluding the findings on testis and epididymis were generally reversible. Most of the findings for a reference drug, VCR, were similar to those for VP, and their severities brought by VP 1.5 and 4.5 mg/kg were comparable to those by VCR 0.04 and 0.08 mg/kg, respectively. Based on these results, the non-effect dose level of VP under the present experimental condition was estimated to be 0.15 mg/kg/day against rats of both sexes.
