目的:观察天王补心丸的抗抑郁作用及其对雄性大鼠性功能的影响,旨在发掘天王补心丸的作用特点.方法:通过小鼠悬尾、强迫游泳和自发活动实验验证其抗抑郁药效与5-HT1A受体的关系;通过大鼠交配行为和非接触阴茎勃起实验验证药物对雄性大鼠性功能的影响,同时加入5-HT1A受体阻断剂WAY100635探讨其可能作用机制;ELISA法检测大鼠血清雄激素水平.结果:与空白组比较,天王补心丸低、中、高剂量组,氟西汀组,天王补心丸+WAY100635组小鼠悬尾不动时间显著降低(P<0.05,P<0.01),天王补心丸中、高剂量组,氟西汀组及天王补心丸+WAY100635组小鼠强迫游泳不动时间显著降低(P<0.05),说明天王补心丸有显著的抗抑郁作用,且与5-HT1A受体无关.在大鼠性功能实验中,与空白组比较,氟西汀组雄性大鼠爬垮潜伏期、插入潜伏期和射精间歇时间显著延长(P<0.01),爬垮次数、插入次数和射精次数显著减少(P<0.01),阴茎勃起次数也显著减少(P<0.01),而天王补心丸无此作用,合用WAY100635后氟西汀的性功能障碍作用消失;同时,所有药物对大鼠雄激素均无显著性影响.结论:天王补心丸的抗抑郁作用可能与5-HT1A受体无关,且对雄性大鼠性功能没有影响,优于氟西汀.
目的:研究天王补心丸对慢性应激抑郁模型小鼠行为学、下丘脑-垂体-肾上腺轴(HPA轴),海马糖原合酶激酶3β(GSK3β)磷酸化及脑源性神经营养因子(BDNF)表达的影响,初步探讨其抗抑郁作用机制.方法:将60只雄性ICR小鼠按照糖水偏嗜度随机分为正常组、慢性应激模型组、盐酸氟西汀组(10 mg·kg-1)以及天王补心丸高、中、低剂量组(3.6,1.8,0.9 g·kg-1).采用慢性不可预知应激实验(CUS)建立抑郁症小鼠模型,各给药组灌胃给药28 d后通过糖水偏好实验、开场行为实验、新奇抑制摄食实验检测其行为学变化.之后分别取小鼠血、肾上腺及海马组织,采用酶联免疫吸附测定(ELISA)法检测小鼠血清中促肾上腺皮质激素(ACTH)和皮质酮(CORT)含量,蛋白免疫印迹法(Western blot)检测海马组织中GSK3β磷酸化及BDNF表达的变化,并计算肾上腺指数.结果:与正常组比较,模型组小鼠的蔗糖水偏嗜度显著降低(P<0.01),开场活动次数明显减少(P<0.05),新奇抑制摄食潜伏期延长(P<0.01),血清ACTH,CORT含量民明显升高(P<0.05,P<0.01),海马组织中GSK3β磷酸化及BDNF表达显著降低(P<0.01),肾上腺指数显著升高(P<0.01);与模型组比较,天王补心丸可以逆转抑郁症模型小鼠行为学变化(P<0.05,P<0.01),显著降低抑郁症模型小鼠血浆ACTH和CORT的含量(P<0.01)和肾上腺指数(P<0.01),同时增加小鼠海马GSK3β磷酸化及BDNF表达水平(P<0.05,P<0.01),其作用效果与盐酸氟西汀相当.结论:天王补心丸对慢性不可预知应激抑郁模型小鼠具有显著的抗抑郁作用,其作用机制与抑制HPA轴活性、上调海马GSK3β磷酸化及BDNF的蛋白表达有关.
This study aimed to investigate the antidepressant effects of Puyu Capsules and its potential mechanism. The antidepressant activity of Puyu Capsules was evaluated by forced swimming test(FST) and tail suspension test(TST) after subchronic administration in mice. Next, the mice were subjected to a chronic unpredictable stress(CUS) protocol for a period of 28 d to induce depressive-like behaviors. Then, a sucrose preference test, open-field test and novelty-suppressed feeding test were performed to evaluate the antidepressant effect of Puyu Capsules. After the behavioral test, the adrenal index was calculated; the levels of serum corticosterone(CORT) and adrenocorticotropic hormone(ACTH) were detected by enzyme-linked immunosorbent assay(ELISA); the levels of glucocorticoid receptor(GR), protein expression of brain-derived neurotrophic factor(BDNF), and the ratio of phosphorylated cAMP response element binding protein(CREB) to total CREB were detected by Western blot to explore the antidepressant function and mechanism of Puyu Capsules. The results suggested that Puyu Capsules had significant antidepressant effects on both the depression model and CUS model. At the same time, the drug could prevent the change of adrenal index induced by CUS and reverse the abnormal activation of CORT and ACTH in the serum of depressed mice. Finally, Puyu Capsules could also reverse the lower expression of pCREB, BDNF and GR in the hippocampus of CUS mice. In conclusion, Puyu Capsules produced significant antidepressant effects, and the mechanism was closely related to hypothalamic pituitary adrenal(HPA) axis activity, GR and CREB-BDNF pathway expression.
Objective:To observe the impacts of Jieyu capsule (Puyu capsule) on mice of drug-induced depression model and the possible mechanism of action.Methods:The mice were divided randomly into control group,imipramine group,Jieyu capsule (Puyu capsule) low-dosage group (235 mg · kg-1),Jieyu capsule(Puyu capsule) medium-dosage group (470 mg · kg-1) and Jieyu capsule(Puyu capsule) high-dosage group(940 mg · kg-1) according to body weights.A reserpine-induced depression model was produced through reserpine antagonism experiment,and the impacts of Jieyu capsule (Puyu capsule) on reserpine-induced body temperature drop,acinesia and ptosis were observed;then the times of mice twitching heads and fatality rate caused by yohimbine were observed through serotonine-induced head twitching experiment and yohimbine toxicity experiment,and also the impacts of drugs on serotonine and norepinephrine in mouse body were observed.Results:After being injected with reserpine,animals were reserpinized,i.e.,subjected to body temperature drop,acinesia and ptosis;Jieyu capsule of different dosages could antagonize its actions remarkably.In serotonine-induced head twitching experiment,it was observed that the times of head twitching of the mice taking Jieyu capsule(Puyu capsule) hadn't increased remarkably.In yohimbine toxicity experiment,it was observed that the mediumdosage and high-dosage Jieyu capsule(Puyu capsule) could both add yohimbine's toxicity.Conclusion:Jieyu capsule (Puyu capsule) has the anti-depression effect on reserpine-induced depression model mice;its mechanism of action is likely to be related to the enhancement of neurologic function of norepinephrine in the brain.
目的 从解郁合欢汤、血府逐瘀汤和天王补心丹3种复方水煎剂中初步筛选出有潜在抗抑郁效果的复方. 方法 取健康SPF级雄性KM小鼠50只,根据旷场试验结果随机分成空白组、盐酸氟西汀组、解郁合欢汤组、血府逐瘀汤组和天王补心丹组5组,每日灌胃给药1次,连续给药14d.每周进行悬尾试验、强迫游泳试验观测小鼠行为学变化;给药结束后测定小鼠自发活动;行为学试验结束后,用Western Blot法测定小鼠海马p-GSK3β的表达量. 结果 ①与空白组相比,血府逐瘀汤组和天王补心丹组在给药第1周和第2周均能显著缩短小鼠悬尾和游泳不动时间,作用与盐酸氟西汀组相当,其中天王补心丹组作用最显著;解郁合欢汤组有作用趋势,但无显著性差异.②3种复方均不影响小鼠自发活动.③3种复方均能增加小鼠海马p-GSK3β的表达量,天王补心丹组作用最显著. 结论 天王补心丹抗抑郁效果较强,其作用机制可能与增加海马p-GSK3β的表达有关.
