All leprosy patients exhibited higher total LDH activity as compared to normals. M/H ratio was significantly increased in patients of Lepromatous leprosy and correlated closely with the clinical severity and advancement of disease. Tuberculoid leprosy patients showed values close to normals. Hence M/H ratio could demarcate two polar types of leprosy i.e. Tuberculoid and Lepromatous leprosy. Clofazimine treatment over a period of one year in patients with suspected DDS resistance and repeated attacks of lepra reaction decreased total LDH activity and M/H ratio considerably. Fall in M/H ratio during Clofazimine treatment could be attributed to the clearance of 'M' subunits by the drug due to removal of blockade of R.E.S. system produced by lepra bacilli.</p>  a0254-9395
