    • 摘要: 目的:探讨高原低氧环境下红景天苷对小鼠运动耐力的影响。方法:C57BL/6J健康雄性小鼠随机分为常氧对照组、模型对照组、红景天胶囊组及红景天苷小剂量(5 mg/kg)、中剂量(10 mg/kg)、大剂量(20 mg/kg),每组15只。除外常氧对照组外,各组按剂量预防给药3 d后急进海拔4010 m的高原,缺氧暴露1 d后采用力竭游泳实验测定小鼠力竭时间;苏木精-伊红染色观察肝及肌肉组织的病理学变化;检测并比较各组丙二醛(MDA)、过氧化氢(H2O2)、谷胱甘肽(GSH)、总超氧化物歧化酶(T-SOD)、糖原、乳酸、腺苷三磷酸(ATP)酶活性水平。结果:与常氧对照组比较,模型对照组力竭游泳时间缩短(P<0.05),肝及肌肉组织出现病理损伤、氧化应激水平显著提高、钠钾ATP酶和钙镁ATP酶活性升高、糖原含量减少;与模型对照组比较,红景天胶囊组和红景天苷各剂量组力竭游泳时间显著延长(均P<0.05),肝、肌肉组织的病理损伤减轻,且肝、肌肉组织中MDA、H2O2、乳酸含量不同程度降低,GSH、肝糖原和肌糖原含量增加,T-SOD、ATP酶活性增强(均P<0.05)。结论:红景天苷具有显著的抗疲劳活性,其抗疲劳作用与减少氧化应激损伤、降低不良代谢产物的堆积和增加能量物质的储备相关。

    • 摘要: 制备蛹虫草面条并研究其对缓解小鼠体力疲劳及血脂浓度的影响。将小鼠分为饲料组、空白面条组、低剂量蛹虫草面条组和高剂量蛹虫草面条组,建立游泳疲劳动物模型,记录各组小鼠的力竭游泳时间,并测定各组小鼠体内关于疲劳、血脂浓度的相关指标。结果表明:各组小鼠体重增长无明显差异;与饲料组、空白面条组相比,蛹虫草面条组能高效延长小鼠力竭游泳时间(P<0.01),高剂量组小鼠的平均力竭游泳时间可达3817.50 s,是饲料组的2.33倍,是空白面条组的2.35倍;在面条中添加高剂量的蛹虫草粉能够显著提高小鼠乳酸脱氢酶、高密度脂蛋白的含量,增加糖原的储备量,抑制血清中尿素氮的堆积,降低甘油三酯、总胆固醇的含量(P<0.05)。蛹虫草面条不影响小鼠正常生长发育,且具有显著地缓解体力疲劳、降低体内血脂浓度的功效。

    • 摘要: 本文研究了短期食用菊粉对于小鼠抗疲劳能力的影响.通过不间断灌胃给予小鼠低(0.4 mg/kg)、高(2 mg/kg)剂量的菊粉45 d,在末次给药半小时后,测试了小鼠力竭游泳时间,强迫游泳后血清肌酸激酶(creatine kinase,CK)活性、血乳酸(lactic acid,LA)和血尿氮素(blood urea nitrogen,BUN)含量及小鼠粪便菌群丰度.结果显示,低剂量与高剂量组的力竭游泳时间与空白组相比分别提高45.62%与90.52%倍(p<0.05).在剧烈运动后,与空白组相比,低剂量组与高剂量组小鼠血清中的CK活性分别下降为17.07% 与53.65%(p<0.05);BUN含量分别下降68.70%与81.28%(p<0.05);全血中的LA含量分别下降为16.29%与41.85(p<0.05).在调节肠道菌群方面,相较于空白组,给药组肠道有害菌(变形菌门细菌)均有下调,其中高剂量组的菌群丰度最高.实验结果说明短期食用菊粉可以提高机体的抗疲劳能力,其作用机制可能与菊粉能调节肠道菌群丰度相关.

    • 摘要: Objective To assess the effect of electroacupuncture (EA) on chronic inflammatory response of Leydig cells in aged rats with low testosterone ,so as to investigate its underlying mechanism of anti-male reproductive aging .Methods Twenty-four 20 months old SD rats were randomly divided into EA ,medication and aged control groups ( n= 8 in each) ,and other 8 young SD rats (2 months of age) were used as the youth control group .EA (2 Hz/100 Hz ,1 mA) was applied to"Guanyuan"(CV 4) and bilate-ral"Shenshu"(BL 23) for 15 min ,once daily for 8 weeks except the weekends .The medication group received abdominal subcu-taneous injection of testosterone propionate (7 mg · kg-1 · 3 d-1 ) for 8 weeks .The aged control group and the youth control group received subcutaneous injection of 0 .9% normal saline ,with the same dose and same treatment frequency as those of the medication group .The rats' physical power was assessed according to the exhausted swimming duration ,and the levels of serum total testosterone (TT) and free testosterone(FT) were determined by ELISA .The pathological changes of the testis tissue were detected by using H .E .staining ,and the immunoactivity of cyclooxygenase-2 (COX-2) in Leydig cel s was detected by immunohisto-chemistry .The expression levels of nuclear factor-κB p 65 (NF-κB p 65) ,COX-2 ,interleukin-1 β (IL-1 β) and tumor necrosis factor-α (TNF-α) proteins in the testis tissues were determined by Western blot .Results Before and after treatment ,the exhaustive swimming duration and the levels of serum TT and FT in the aged control group were significantly lower than those of the youth control group ( P < 0 .01) .After the treatment ,the exhaustive swimming duration and serum TT and FT in the EA and medi-cation groups were notably higher than those in the aged control group ( P<0 .01) .HE staining showed that the incompleteness of basement membrane of spermatogenic tubules ,reduction of spermatogenic cells and supporting cells and irregularity of Leydig cells in the testis tissue of the aged rats were relatively milder after EA intervention .Compared with the youth control group ,the expression levels of NF-κB p 65 and COX-2 ,IL-1β and TNF-αin the testicular tissue were significantly higher in the aged control group ( P<0 .01) ,while in compared with the aged control group ,the expression levels of NF-κB p 65 ,COX-2 ,IL-1β and TNF-αproteins were significantly down-regulated in the EA group ( P<0 .01) .Conclusion EA intervention can improve the physical power of the aged rats with low testosterone ,which may be related to its effects in up-regulating TT and FT levels ,and in reducing chronic in-flammatory response in the testis tissue .%目的:探讨电针对睾酮低下老年大鼠睾丸间质细胞(L ey dig细胞)慢性炎性反应的影响及其抗雄性生殖衰老的可能机制.方法:SD老年大鼠随机分为电针组、药物组、老年对照组,每组8只,SD青年大鼠8只作为青年对照组.电针组取"肾俞""关元"穴予电针治疗,持续15min,每日1次,治疗5d休息2d,连续8周.药物组予腹部皮下注射丙酸睾酮注射液(7 mg·kg-1·3 d-1),连续8周.老年对照组和青年对照组给予腹部皮下注射0.9% 氯化钠溶液,注射剂量及疗程同药物组.治疗前后观察大鼠力竭游泳时间,采用ELISA法检测大鼠血清睾酮(T T)和游离睾酮(FT)水平,免疫组化法检测Leydig细胞环氧化酶-2(COX-2)蛋白表达水平,Western blot法检测大鼠睾丸核因子-κB p 65(NF-κB p 65)、COX-2、白介素-1β(IL-1β)及肿瘤坏死因子-α(TNF-α)蛋白表达水平.结果:与青年对照组比较,老年对照组力竭游泳时间及血清TT、FT水平降低(P<0.01);治疗后,电针组与药物组力竭游泳时间及血清TT、FT水平高于老年对照组(P<0.01).与青年对照组比较,老年对照组睾丸NF-κB p 65、COX-2及其下游炎性因子IL-1β、TNF-α表达明显上调(P<0.01);与老年对照组比较,电针组可显著下调睾丸NF-κB p 65、COX-2、IL-1β及TNF-α蛋白的表达水平(P<0.01).结论:电针能改善睾酮低下老年大鼠血清TT及FT含量,并能降低老年大鼠睾丸组织的炎性反应,这可能是改善雄性生殖衰老的机制之一.
