 AB    The effect of trichosanthin (TCS) on immune system has drawn attentions
       of the investigators both at home and abroad. The purpose of this study
       is to evaluate the prospects of TCS on autoimmune diseases and
       immunodeficiency diseases by detecting the immunoregulatory T
       lymphocytes (T8, 2H4, 4B4) count and cellular DNA content under the
       influence of TCS with flow cytometer using indirect immunofluorescence
       technique and lymphocyte culture in normal subjects and systemic lupus
       erythematosus patients. The results showed that the percentage of T8+
       cells decreased, 4B4+ cells increased, 2H4+ cells did not markedly
       change after adding TCS. The raise of DNA content in S stage was
       dose-dependent to TCS, especially in large doses. It is concluded that
       TCS could selectively inhibit T8+ cells and could obviously increase the
       number of 4B4+ cells. It is suggested that TCS could enhance humoral
       immunity through the ratio of immunoregulatory T cells. So TCS might
       help immunodeficiency patients such as AIDS to reestablish their immune
       system.
