[Determination of lymphocyte subsets in pulmonary tuberculosis by Mc-Ab- rosette reagent method]

The lymphocyte subsets in peripheral blood were determined in 73 cases of active pulmonary tuberculosis and 40 healthy subjects using rosette reagent of monoclonal antibody (McAb) to anti-T lymphocyte. The results showed that the percentages of T3, T4, T8, and T4/T8 ratio were 54.3 +/- 6.7%, 34.3 +/- 7.9%, 35.5 +/- 10.0%, 1.0 +/- 0.4 of patients group 66.3 +/- 7.9%, 45.3 +/- 6.3%, 29.9 +/- 5.8% and 1.6 +/- 0.3 of healthy control group respectively. There was statistically significant difference between these two groups (P less than 0.01).
