The longterm survival and occurrence of neoplastic and nonneoplastic lesions following total body irradiation (TBI), 8.5 Gy, with or without additional cyclophosphamide (Cy; 100 mg kg-1 i.p.) treatment as a conditioning regimen for bone marrow transplantation (BMT) were studied in male BN/BiRij rats. The two groups of rats that were treated with Cy (Cy and Cy + TBI) that survived beyond 100 days after treatment, had a severely decreased median (post treatment) survival time (Cy + TBI: 14.5 months and Cy: 14.1 months). Survival time in the TBI group was moderately decreased (18.5 months) as compared with the untreated controls (27.2 months). All treatment modalities were carcinogenic according to the raw data. After Cy-treatment a high incidence of, frequently multiple, malignant nerve-sheath tumours (Cy: 66 per cent, Cy + TBI: 31 per cent, controls: 2 per cent) was observed. TBI induced an increased occurrence of a great variety of tumours, especially mesenchymal tumours. This effect was more pronounced in animals receiving TBI alone as compared to animals receiving the combined treatment of Cy + TBI; an effect that most likely resulted from the longer median survival after TBI. The multi-target effect of TBI was also reflected in the occurrence of nonneoplastic effects in a variety of tissues, including high incidences of biliary cysts in the liver and severe
testicular atrophy
. The most important Cy-induced nonneoplastic lesion was incisor dysplasia, which resulted in feeding problems that could only be partly overcome by administering powdered food. Early mortality in the Cy-treated groups was associated with
emaciation
and generalized organ atrophy. A more definitive estimate of the late effects of supralethal chemoradiotherapy as part of a treatment of malignant disease has to await the results of various conditioning regimens for BMT in rats employing the acute BN myelocytic leukaemia (BNML) as a rat model for human acute myelocytic leukaemia (AML).

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.
