Assessment of diluted Dharmendra lepromin.

Twenty-one patients of lepromatous and tuberculoid type were tested with standard, 1:2 and 1:4 diluted Dharmendra lepromin. It was found that correlation exists between the degree of induration and the number of bacilli in the lepromin. Uniform and reproducible results were obtained with Dharmendra antigen containing 40 million bacilli/ml. This is of special significance in enhancing the present meagre supplies of lepromin.

T and B lymphocytes and blastogenesis in leprosy.

T and B cell percentages and their blastogenic response to PPD and lepromin have been studied in 107 patients of various types of leprosy. T cell counts and their blastogenic response were found to be considerably lower in all types of leprosy as compared to the normal. The counts and stimulation were the lowest for lepromatous leprosy. B cell counts were unaltered in all types of leprosy.

Histopathologic study of clinically normal appearing skin in lepromatous leprosy.

Skin biopsies from clinically normal skin of the scalp, axillary and groin regions in 20 lepromatous leprosy patients revealed significant histopathological findings in upto 25 percent of the patients. The positive findings could, perhaps, be enhanced by studying larger skin materials from these body areas. Indeed, no skin area appears to be immune from invasion by Myco. leprae.

Study of apparently uninvolved skin in leprosy as regards bacillary population at various sites.

Slit smears form 16 LL and 4 BL patients were taken from scalp, axilla, inguinal regions and apparently involved skin patch. The bacilli were found in 100% LL and 75% BL patients at all sites. Scalp showed AFB in all LL and 3 out of 4 BL cases. No lesions were seen on the scalp. Bacterial morphology showed no uniform pattern. Contrary to belief, no immune zones were found on the skin as judged by results of bacteriological examination. Our studies do not support the view that the leprosy bacillus has a predilection for sites with relatively low temperature as far as human leprosy is concerned.
