China Oncology 1998;0(04):-
PURPOSE To sutdy the effects of dibutyl pathalate (DBP) on the proliferation and apoptosis of leukemic cells from patients suffering from acute leukemia. METHODS The cell culture in vitro was used to study the effect of DBP on the proliferation of leukemic cells, while agrose gel electrophoresis of DNA fragments was used to study the effect of DBP on apoptosis of leukemic cells. RESULTS DBP could inhibit the proliferation of leukemic cells got from patients suffering from acute leukemia in vitro. The percentage of inhibition were 24.24% and 36.33% respectively when leukemic cells were exposed to 50?g/ml and 200?g/ml DBP for 24 hours. Leukemic cells from acute myelogenous leukemia were more susceptive to DBP than those from acute lymphocytic leukemia. DBP also induced the leukemic cells from patients to die via apoptosis and showed typical "ladder" of DNA fragments for apoptotic cells in agrose gel electrophoresis. CONCLUSION DBP could clear the leukemic cells in bone marrows of patients suffering from acute leukemia by suppressing the growth of leukemic cells and inducing them to die via apoptosis.

Objective To study the effect of rapamycin on the balance of T helper cell subsets in rats with pulmonary fibrosis. Methods Fifteen male Sprague-Dawley (SD) rats were randomly divided into control group, model group and rapamycin group, with 5 rats in each group. Pulmonary fibrosis model was reproduced by using the method of intratracheal instillation of bleomycin (5 mg/kg). Control group was treated by intratracheal instillation of saline (1.25 mL/kg) to obtain the negative control. The rats of the rapamycin group were given rapamycin (1 mg·kg-1·d-1) by gastric perfusion for consecutive 10 days beginning on the 3rd day after intratracheal instillation of bleomycin. On the 28th day all rats were sacrificed, and the peripheral blood and the lung tissues were harvested. The lung tissue was observed. And the severity of pulmonary fibrosis in rats was assessed by Ashcroft score. The lung tissues were performed using immunohistochemical staining to detect the expression ofγ-interferon (IFN-γ) and interleukins (IL-4, IL-17). Flow cytometry was used to detect the percentages of CD4+ T cells and CD8+ T cells. Results The severity of pulmonary fibrosis was improved in rats of rapamycin group compared with that of model group, and the Ashcroft score was decreased (2.92±0.64 vs. 5.76±1.76, F = 16.276, P = 0.080). The expression levels of IL-4 and IL-17 (A value) in model group were the highest (4 789.0±1 014.6, 19 139.0±2 433.3), followed by those of the rapamycin group (3 547.0±953.8, 10 380.0±2 352.4), and the least was found in the control group (1 627.0±914.8, 4 419.0±923.6). The expression levels of IFN-γ (A value) in control group were the highest (9 956.0±1 172.6), followed by those of the rapamycin group (7 487.0±998.4), and the least was found in the model group (6 054.0±1 045.2). There were significantly differences in above parameters among three groups (all P<0.01). Compared with the control group and model group, the percentages of CD4+CD25+Foxp3+T cells in CD4+CD25+, CD4+cells, and lymphocytes were significantly increased in rapamycin group [(57.36±8.84)% vs. (41.28±5.91)%, (34.52±4.56)%; (4.77±0.48)% vs. (3.15±0.37)%, (3.14±0.28)%;(1.97±0.22)%vs. (1.24±0.17)%, (1.44±0.21)%, all P<0.05], and the percentages of CD8+CD25+Foxp3+T cells in CD8+CD25+, CD8+cells, and lymphocytes were also significantly increased in rapamycin group [(73.92±7.69)% vs. (33.44±4.46)%, (49.14±11.38)%; (1.73±1.05)% vs. (0.46±0.15)%, (0.71±0.42)%;(0.31±0.20)% vs. (0.09±0.04)%, (0.14±0.09)%, all P < 0.05]. The percentage of CD8+CD25+Foxp3+ T cells in CD8+CD25+in model group was significantly higher than that in control group [(49.14±11.38)% vs. (33.44±4.46)%, P < 0.05]. Conclusions T helper cell subsets are imbalanced in pulmonary fibrosis rats. Rapamycin can prevent bleomycin-induced pulmonary fibrosis, and its antifibrotic effect maybe the promotion of proliferation and function of regulatory T cells and imbalance regulation of T helper cell subsets.
