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.

The effects of dextroamphetamine on kinesthetic figural aftereffects.

The effect of dextroamphetamine, primarily a central stimulant, on kinesthetic figural aftereffects (KFAEs) was examined. The subjects were selected after preliminary testing with the Eysenck Personality Inventory and were classified into three groups: extraverts, ambiverts, and introverts. d-Amphetamine was used at three dose levels and a control group was included for purposes of comparison. The 3 X 4 randomized block design was replicated ten times. KFAEs were measured under two sets of conditions, i.e., before and after the induction experience. The results support the following conclusions: (1) neither personality grouping nor drug treatment during preinduction trials significantly affected KFAE; (2) both types of variables were, however, significantly related to behavior during the postinduction trials; (3) the extraverted subjects showed larger KFAEs than ambiverted and introverted subjects under placebo condition; (4) the extent of KFAE was reduced in extraverted and enhanced in introverted subjects under the influence of the drug; (5) there were significant interactions between the drug treatments and personality variables in effects on KFAE.

Immunological studies in psoriasis.

The mean values of serum immunoglobulins A, G, M and D levels in 42 psoriasis patients showed no significant difference from those of control subjects. Analysis of the same sera for the presence of antiglobulin antibodies also yielded negative results. Antinuclear factor could be demonstrated in only 4.8% of the cases. The possibility that serum antiglobulins get drained into the lesions making their detection in the serum difficult, is supported by our preliminary findings of focal deposition in the stratum corneum of immune complexes of IgG, IgM and complement in tissue sections of psoriatic lesions from these patients.
