RESUMO
OBJECTIVE: To assess the efficacy of primary chemotherapy in patients with clinically staged Hodgkin's disease. DESIGN: Non randomized study. SETTING: Pediatric Oncology Division of Regional Cancer Center. SUBJECTS: Twenty nine children with Hodgkin's disease. INTERVENTIONS: Chemotherapy was given to 21 patients whose parents agreed for the same. Sixteen children received COPP regimen and 5 received MOPP regimen. RESULTS: Complete remission was achieved in 19 patients. The relapse free survival and overall survival in these patients were 76% and 86%, respectively at 5 years. There was no death related to chemotherapy toxicity. CONCLUSION: Combination chemotherapy is an effective modality of treatment for children with Hodgkin's disease.

Eventhough neuroblastoma presents with wide spread tumour dissemination, metastasis to testes had rarely been reported. We report a case of Stage IV neuroblastoma who developed metastasis to both testes. He had massive infra-diaphragmatic disease with involvement of left supraclavicular lymph node at presentation. Treatment received by him was not adequate and five months later he developed metastasis to both testes. Hematogenous spread might have been the possibility in this case.

Guinea pigs were given ascorbic acid orally in two doses; a low and a high dose. The tissue levels of ascorbic acid-2-sulphate was estimated in these animals after 15 days of feeding and a subsequent deprivation period of 15 days. The specific activity of the enzymes ascorbic acid sulphotransferase and ascorbic acid-2-sulphate sulphohydrolase was studied. During higher ascorbic acid intake, the activity of ascorbic acid sulphotransferase was increased, whereas ascorbic acid-2-sulphate sulphohydrolase showed a decreased activity. But when ascorbic acid intake was lowered or ceased, the activity of the above enzymes showed a reverse pattern. Possible reasons for the lack of antiscorbutic activity of ascorbic acid-2-sulphate in guinea pigs is discussed.
