RESUMEN

OBJECTIVE: To study the clinical and biochemical spectrum of Gaucher disease. DESIGN: Assay of beta glucosidase enzyme in leucocytes in patients with splenomegaly, and in chorionic villi for prenatal diagnosis. SETTING: Hospital-based. SUBJECTS: Of 13 cases of Gaucher disease, aged 1-6 years, 9 were identified at Delhi and 4 at Bombay. RESULTS: The enzyme beta-glucosidase was 0.65 nmol/h/mg of protein or less in all the cases in Delhi, and 2.5 nmol/h/mg of protein or less in Bombay. All cases except one belonged to type 1 (hepatosplenomegaly), while one case was of type 2 (neuronopathic). Prenatal diagnosis was carried out in one family and the fetus was found to be affected. CONCLUSION: In children with hepatosplenomegaly and increased acid phosphatase, assay of beta-glucosidase enzyme confirms the diagnosis of Gaucher disease. Diagnosis of the disease is important because enzyme replacement therapy is available and prenatal diagnosis is possible.

RESUMEN

Diseases like tropical ataxic neuropathy and endemic goitre have been reported to have definite correlation with a chronic ingestion of cassava (Manihot esculenta Crantz). The toxicity of cassava has been attributed to its two cyanogenic glycosides, linamarin and lotaustralin. In this study, an attempt has been made to understand the pattern of changes in certain clinically significant enzymes brought about by the chronic administration of sublethal doses of linamarin to rabbits. The profound elevation in rhodanese activity observed in the linamarin and cyanide treated rabbits indicated the attempt of the tissues to detoxify cyanide. That intact linamarin could be hydrolysed in vivo was a significant finding from the study. The mode of toxicity of linamarin was similar to that of cyanide by producing a gradual shift from aerobic to anaerobic metabolism.
