T and B lymphocytes were separated by resetting procedures.After lymphocytes were labelled by T4 McAb, T4* and non~T4* cells were obtained by cell affinity chromatography method.When parts of T, B, T4* and non-Tt+ cells were exposed to 10 Gy 6CCo Y-rays, the stimulating function of pokeweed mitogen and the effect of G1Co Y-rays on lymphocytes were observed by technique of ?H-TdR incorporation. The results showed that when T4 + , Tg* and HI43+ cells were labelled after irradiation at a dose of 0 .1 Gy within one hour,the number of positive cells decreased significantly .The cells radiosensi-tivity in the group of T8 + , and HI4,+ lymphocytes had no significant difference and were higher than that in the group of T4* lymphocytes. PWM can stimulate both T and B cells but B cells were more sensitive to PWM. The response of B cells to PWM was the same as that of non-T4+ cells. The response of T4* cells to PWM was the lowest. Both T and T4* lymphocytes were synergetic to B lymphocytes but such a kind of synergistic effect in T cells were more obvious than that in T4+ group.When T and T4+ or B lymphocytes were irradiated by 10 Gy "'Co Y-rays, their synergistic effect disappeared.Neither synergistic nor suppresstve effect was found between the cells in B group and non-T^ group.When T4*, B and non-T4* cells had been exposed to 10 Gy irradiation, the value of 'H-TdR incorporation in B and non-T4* cells decreasing had no significant difference but their decreasing value was more obvious than that in T4* group.

T_4~+ and non-T_4~+ cells were exposed to 10 Gy ~(60)Co γ-rays, the function of poke-weed mitogen (PWM) and ~(60)Coγ-rays irradiation effect on lymphocytes were investiga-ted by technique of ~3H-TdR incorporation. The results showed that PWM can induce both T and B lymphocytes but B lym-phocytes were more sensitive to PWM. The response of B lymphocytes to PWM wasthe same as that of non-T_4~+ cells, the response of T_4~+ cells to PWM was the lowest.DNA synthesis of both T and T_4~+ lymphocytes were synergistic to B lymphocytes.The synergistic effect in T and B lymphocytes was more strong than that in T_4~+ andB lymphocytes. When T and T_4~+ or B lymphocytes were irradiated by 10 Gy ~(60)Co γ-rays, the synergistic effect disappeared. Neither synergistic nor suppressive effect wasfound between non-T_4~+ and B lymphocytes. When T_4~+, B and non-T_4~+ lymphocyteshad been exposed to 10 Gy irradiation, the percentage suppression of ~3H-TdR incorporation between B and non-T_4~+ lymphocytes had no significant difference but was higherthan that in T_4~+ lymphocytes.
