RESUMEN

ObjectiveTo explore the effect and mechanism of LQC on the immune function of B lymphocytes and NK lymphocytes in mouse with impaired immune function. Methods Mice with impaired immune function led by Cyclophosphamide (Cy)were used as experimental animmals, and divided into five groups randomly, twelve mice in every group, which is NS control group, Cy control group, Cy+ LQC minor and major dose group, and Cy + LQC decoction group. NS control group was given NS 0.2 ml/d subcutaneously 10 d, and the rest groups were given Cy 0.8 ml/d subcutaneously (20 mg/kg · d-1) 10d, to establish a mouse model of immune dysfunction. Since the 11th day each group was given NS, Cy, LQC minor dose, major dose and fructus ligustri lucidi decoctoin. Mice of each group were killed after 7 days. The percentage of B lymphocytes (CD3 - CD19 + ) and NK lymphocytes (CD3 - CD 16 + CD56 + ) in the peripheral blood of the experimental mice were detected by flow cytometer. ResultsIn comparison with LQC major dose group [ (20.44± 1.78)and(19.12± 1.70) ], fructus ligustri lucidi group[ (19.90± 1.42) and (20.17± 1.66) ], CD3-CD19+and CD3-CD16+CD56+ cells of LQC minor dose group[ (11.54±0.98) and (12.46±0.08)]were decreased significantly (P<0.01), which were increased significantly compared with Cy group[ (4.53± 1.70) and (5.03 ±1.22) ] (P< 0.01), but they had no significant difference with NS [ ( 11.84 ± 0.99) and ( 12.90± 0.28) ] (P > 0.05).In comparison with Cy group and NS group, CD3-CD19+ and CD3-CD16+CD56+ cells of LQC major dose group were increased significantly (P<0.01), which had no significant difference with fructus lignstri lucidi group (P>0.05). Conclusion The immune functions of the mice with impaired immune function were improved by LQC, it also could increase the quantity ofCD3-CD19+ cell and CD3-CD16+CD56+ cell. The dose of LQC was positively correlated with the modulation effect of LQC on the immune function.

RESUMEN

Objective To evaluate the effect of Chinese herbal medicine immunomodulator on T lymphocyte immune function in peripheral blood and intestinal mucosa of immature rats with obstructive jaundice. Methods Three-weeks Wistar rats were randomly divided into four groups. (n= 12, in each): normal control group, sham operation group, obstructive jaundice (OJ) group, OJ + Chinese herbal medicine immunomodulator (OJ+ZY) group. Except for the normal control group, the others' bile duct stones were ligatured to establish rat models with obstructive jaundice. The percentage of CD4+ and CD8+ tlymphocytes and the ratio of CD4+/CD8+ in peripheral blood and intestinal mucosa of immature rats was detected by flow cytometry. Results The percentage of CD4+ cell [(36.2 ±4.2)%, (28.8±1.8)% respectively] and the ratio of CD4+/CD8+ [(1.14±0.39), (1.37±0.34)respectively] in OJ group were lower than those in normal control group [peripheral blood: CD4+(41.5±5.3)%,CD4+/CD8+(1.37±0.19); intestinal mucosa: CD4+(32.3± 2.4)%, CD4+/CD8+ (1.84+0.28) and sham operation group (peripheral blood: CD4+ (41.2±5.5)%, CD4+/CD8+ (1.45±0.27); intestinal mucosa: CD4+(31.5 ± 2.7)%, CD4+/CD8+ (1.63±0.58)] . The difference was statistical significant(P<0.05). The percentage of CD4+ cell [(42.7±6.3)%, (33.6±2.4)% respectively] and the ratio of CD4+/CD8+ [(1.56±0.46), (1.84±0.56)respectively] in OJ+ZY group, were higher than those in OJ group(P<0.05). The difference was statistical significant(P<0.05). Conclusion Chinese herbal medicine immunomodulator can increase T lymphocyte immune function in immature rats with obstructive jaundice, but has no significance in normal control group as well as sham operation group.

RESUMEN

Objective To evaluate the effect of Astragalus on T lymphocyte immune function in peripheral blood and intestinal mucosa of immature rats with obstructive jaundice. Methods Three-week-old Wistar rats were randomly divided into four groups(n=12,in each):control group, sham operation group, obstructive jaundice(OJ)group,OJ+Astragalus (OJ+A)group.The percentage of CD4 and CD8 T lymphocytes, the ratio of CD4 to CD8 in peripheral blood and intestinal mucosa of immature rats was detected by flow cytometry. Result The percentage of CD4+ cell and the ratio of CD4 to CD8 in the OJ group were lower than those in the control group and the sham operation group,with significant difference(P<0.05).The percentage of CD4 cell and the ratio of CD4 to CD8 in the OJ+A group were higher than those in the OJ group(P<0.05).Conclusion Astragalus can increase T lymphocyte immune function in OJ immature rats.
