Résumé
The present study was undertaken to compare the disturbance in bactericidal power of neutrophils in 25 children having protein caloric malnutrition age and sex matched healthy control subjects. There was a highly significant reduction in the percentage of bacteria killed during incubation in children having PCM as compared to healthy control. A direct relationship existed between total serum proteins and bactericidal activity of neutrophils in children having PCM. The impaired bactericidal power of neutrophils can be attributed to impaired synthesis of lysosomal enzymes, glycolytic activity of neutrophils in children having PCM. The exact mechanisms still remain to be elucidated. Decreased bactericidal activity of neutrophils may be one of the mechanisms responsible for infection.

The present study was conducted in 50 patients of various subtypes of leprosy (Lepromatous, Tuberculoid, Borderline borderline) and 25 healthy control, for detection of Australia antigen and various liver function tests (serum protein, cholesterol, alkaline phosphates, SGOT, SGPT, bilirubin and liver biopsy) to see incidence of Australia Antigen and derangement in liver function. It was concluded that incidence of Australia antigen in study and control group was zero. Total serum protein and serum globulin was increased in lepromatous leprosy. A/G ratio was reversed in 34.3% and 50% in lepromatous and tuberculoid leprosy respectively. Granulomatous hepatitis was seen in 66.66% and 50% cases of lepromatous and tuberculoid leprosy respectively. No relationships was established between hepatic lesion, Australia antigen and liver function test.
