The metabolic shift in cholinesterase activity and inhibitor of hypothalamus pituitary gonadal hormones were hypothesized as resultant effect of Parkinson's disease (PD) which is clinically characterized by a movement disorder. This study therefore examined the effect of turmeric curcumin (CUR) on index of PD, acetylcholine esterase activity and disorder of hypothalamus pituitary gonadal hormone (HPGH) in Bisphenol-A induced injury using animal model. Forty adult male albino rats were randomly distributed into five (n = 8) groups. Group I: vehicle control (olive oil 0.5 ml), Group II was given 50 mg/kg of BPA only, Group III was given 50 mg/kg BPA + 50 mg/kg curcumin, Group IV was given 50 mg/kg BPA + 100 mg/kg curcumin and Group V was administered 50 mg/kg of curcumin only for 14 days. The study examined the effect of curcumin on acetylcholineesterase (AChE) activity, nitric oxide radical (NO) production, HPGH (LH, FSH and testosterone), MDA level, antioxidant enzymes (SOD and CAT), in BPA induced male rat. Sperm parameters were similarly examined. The animals induced with BPA exhibited impairment to striatum, leydig cells and sertoli cells by depleting LH, FSH, testosterone and spermatozoa with reduced AChE activity and significant (p < 0.05) alteration in cerebral enzymatic antioxidants. Locomotive activity was impeded followed by the increase of brain NO level (marker of pro-inflammation). Therapeutically, CUR promoted hypothalamus-pituitary-testicular hormones via modulation of AChE and locomotive activities, reduction of intracellular NO level, prevention of striatum-endocrine injury as well as oxidative damage. Hence, CUR abolished HPGH dysfunction linked with PD mediated by BPA in rat.
胆碱酯酶活性的代谢转变以及下丘脑 - 垂体 - 性腺激素的抑制剂被假定为帕金森病(PD)的结果效应,帕金森病在临床上以运动障碍为特征。因此,本研究使用动物模型,研究了姜黄姜黄素(CUR)对双酚A诱导损伤中帕金森病指标、乙酰胆碱酯酶活性和下丘脑 - 垂体 - 性腺激素(HPGH)紊乱的影响。将40只成年雄性白化大鼠随机分为五组(n = 8)。第一组:载体对照(橄榄油0.5毫升),第二组仅给予50毫克/千克双酚A,第三组给予50毫克/千克双酚A + 50毫克/千克姜黄素,第四组给予50毫克/千克双酚A + 100毫克/千克姜黄素,第五组仅给予50毫克/千克姜黄素,持续14天。该研究检测了姜黄素对双酚A诱导的雄性大鼠乙酰胆碱酯酶(AChE)活性、一氧化氮自由基(NO)产生、HPGH(促黄体生成素、促卵泡生成素和睾酮)、丙二醛水平、抗氧化酶(超氧化物歧化酶和过氧化氢酶)的影响。精子参数也进行了类似检测。双酚A诱导的动物表现出纹状体、睾丸间质细胞和支持细胞受损,促黄体生成素、促卵泡生成素、睾酮和精子减少,乙酰胆碱酯酶活性降低,脑酶抗氧化剂有显著(p < 0.05)改变。运动活性受到阻碍,随后脑NO水平升高(促炎标志物)。在治疗方面,姜黄素通过调节乙酰胆碱酯酶和运动活性、降低细胞内NO水平、预防纹状体 - 内分泌损伤以及氧化损伤,促进下丘脑 - 垂体 - 睾丸激素分泌。因此,姜黄素消除了大鼠中与双酚A介导的帕金森病相关的下丘脑 - 垂体 - 性腺激素功能障碍。
