Evaluation of standard Dharmendra lepromin.

Dharmendra lepromin standardized at Central JALMA Institute for Leprosy (CJIL) by bacterial counts was used by different observers in four different Centres to assess the early and late reactions. Patients taken into the study were from different ethnic groups in different regions of the country. Comparable skin reactions were found at the Bombay Leprosy Project (BLP), Bombay and at the CJIL, Agra wherein a large number of patients were taken in the study. Similarly, when a smaller number of patients were taken in the study at the Base Hospital (BH), Barrackpore, and at the Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Pondicherry, the skin reactions noted in patients at these Centres were again found to be statistically comparable.
