山香圆总黄酮体外对大鼠佐剂性关节炎免疫功能的影响

目的观察山香圆总黄酮(totalflavonoidsofturpiniaargutaseen,TFS)体外对佐剂性关节炎(adjuvantarthritis,AA)大鼠免疫功能的影响。方法选择健康♂SD大鼠,采用弗氏完全佐剂(freundscompleteadjuvant,FCA)诱导AA大鼠模型:将同一批号的的卡介苗80℃水浴1h灭活,用灭菌液体石蜡配成10g·L-1的乳剂。d28处死大鼠,取AA大鼠的免疫细胞(脾细胞和腹腔巨噬细胞)体外给药培养并检测一些免疫指标:细胞增殖法检测ConA、LPS诱导的大鼠脾淋巴细胞增殖反应及IL-1、IL-2的分泌水平;放免法检测PGE2水平。结果与正常组相比,AA大鼠ConA、LPS诱导的脾淋巴细胞增殖功能低下,脾淋巴细胞产生的IL-2活性下降,LPS诱导的大鼠腹腔巨噬细胞产生的IL-1、PGE2水平明显升高。TFS(10-8~10-4)mg·L-1可纠正AA大鼠低下的脾淋巴细胞增殖反应和脾细胞IL-2的产生,降低AA大鼠腹腔巨噬细胞产生过高的IL-1和PGE2。结论山香圆总黄酮对AA大鼠的异常免疫功能具有调节作用。

Antifatigue and increasing exercise performance of Actinidia arguta crude alkaloids in mice

Actinidia arguta (Siebold et Zucc.) Planch. ex. Miq. is one of the most recently domesticated fruit species with increasing commercial production worldwide. It is a well-known traditional Chinese medicine and is used to reduce blood glucose and treat atopic dermatitis. In addition, it possesses antioxidant, anticancer, and antiallergic properties. In this study, we investigated the physical antifatigue and exercise performance effects of A. arguta crude alkaloids (AACA) extracted with 70% ethanol. Four groups of male Kunming mice (n = 16) were orally administered AACA at doses of 0 mg/kg/d (vehicle), 50 mg/kg/d (AACA-50), 100 mg/kg/d (AACA-100), or 200 mg/kg/d (AACA-200) for 28 days. The effect of AACA treatment on exercise performance was studied using the forelimb grip strength experiment and by the measurement of the weight-loaded swimming time. The antifatigue effect is evaluated based on fatigue-associated biochemical parameters, hepatic and muscular glycogen levels, and changes in the morphology of transverse and longitudinal sections of skeletal muscle. The results showed that AACA could elevate the endurance and grip strength in mice. The exhaustive swimming time of the AACA-50, AACA-100, and AACA-200 groups was significantly (p < 0.05) increased compared with the vehicle. The swimming time of the AACA-100 group was the longest among all groups studied. Mice in the AACA-treated groups had decreased levels of lactate, ammonia, and creatine kinase after a physical challenge compared with the vehicle group. The tissue glycogen, an important energy source during exercise, significantly increased with AACA. The morphology of transverse and longitudinal sections of skeletal muscle did not change in the vehicle group. Overall, these findings suggest that AACA possesses antifatigue effects and increases exercise performance in mice. Therefore, A. arguta may be developed as an antifatigue dietary supplement in the category of functional foods.

Therapeutic effects and mechanisms of total flavonoids of Turpinia Arguta Seen on adjuvant arthritis in rats

AIM: To investigate the therapeutic effects and mechanisms of total flavonoids of Turpinia Arguta Seen (TFS) on adjuvant arthritis in rats. METHODS: The model of adjuvant arthritis was induced by injection of Freund's Complete Adjuvant (FCA). Secondary paw swelling of AA rats was measured with volume meter and polyarthritis index were scored. The splenocyte proliferation, (interleukin-1) IL-1 and interleukin-2 (IL-2) production were assayed by cell proliferation assay. Prostaglandin E(2) (PGE(2)) production was determined by radioimmunoassay. RESULTS: TFS (80, 160, 320 mg/kg, i.g.) could significantly inhibit secondary inflammatory reaction (secondary swelling, multiple arthritis, pathologic change of ankle arthritis) in AA rats. The results in vivo showed that the low response of splenocytes to concanavalin A (Con A) and lipopolysaccharide (LPS) and the decreased IL-2 synthesis were restored in AA rats treated with TFS (160, 320 mg/kg, i.g.), while the elevated IL-1 and PGE(2) released from peritoneal macrophages (PMphi) were also reduced. CONCLUSION: TFS has significant therapeutic effect on AA rats, which might be relate to its immunoregulatory actions.
