The percentage of T lymphocytes in lepromatous and tuberculoid cases were significantly lower compared to that in normal healthy controls. All sera except FCS had a stimulatory effect on the number of T cells. The cells incubated for 24 hours in FCS did not show any stimulatory effect on the number of T cells, however, these FCS incubated cells showed a significant elevation in the number of T cells when further incubated in sera either from leprosy cases or from healthy subjects.</p>  a0254-9395
