T & B lymphocytes in the spectrum of leprosy.

The percentage of T & B lymphocytes were estimated in 52 leprosy patients by 'E' and 'EAC' rosette techniques. The mean % values for 'T' lymphocytes were significantly lower in lepromatous group as compared with that of tuberculoid and borderline groups. Also, a significant difference was observed in the mean % values of T & B lymphocytes of the borderline and tuberculoid patients and of the normal control group. These findings were correlated with skin smears and lepromin testing.
