Cinnamomum cassia has been suggested in Ayurveda for the management of sexual dysfunction. This research work was conducted to shed some light on the mechanism of action of the extract, and evaluate the efficacy of its methanol extract in age induced sexual dysfunction in male Wistar rats. Secondary objective of the project was to study the effect of treatment on sperm parameters and smooth muscle:collagen level in rat penile tissue.
Young and aged male rats were treated with methanol extract of Cinnamomum cassia at a dose of 100 mg/kg and sexual behavior was observed on 28th day in presence of female rats in estrous phase. Sildenafil was used as standard medicine. Effect of treatment was studied on epididymal sperm parameters, and Massons trichrome staining of rat penile tissues was performed to know the level of smooth muscle:collagen.
The treatment significantly increased sexual function in aged rats that had decreased in comparison to young rats, but did not have any significant effect on sperm count, live and defective sperm percentage. However, treatment induced an increase in smooth muscle level and a decrease in collagen level in the aged rat penile tissue in comparison to that of age matched control.
Based on our studies, we found that Cinnamomum cassia extract was effective in management of sexual dysfunction in aged rats and hence we propose a possible mechanism of action for Cinnamomum cassia which could be responsible for restoring sexual activity in aged rat.
阿育吠陀医学中已提出肉桂可用于治疗性功能障碍。开展这项研究工作是为了阐明该提取物的作用机制,并评估其甲醇提取物对雄性Wistar大鼠年龄诱导的性功能障碍的疗效。该项目的次要目标是研究治疗对大鼠精子参数以及阴茎组织平滑肌与胶原蛋白水平的影响。
对年轻和老年雄性大鼠给予100毫克/千克剂量的肉桂甲醇提取物进行治疗,并在第28天处于发情期的雌性大鼠存在的情况下观察性行为。西地那非用作标准药物。研究治疗对附睾精子参数的影响,并对大鼠阴茎组织进行马松三色染色以了解平滑肌与胶原蛋白的水平。
与年轻大鼠相比,老年大鼠性功能下降,而治疗显著提高了老年大鼠的性功能,但对精子数量、活精子和有缺陷精子百分比没有任何显著影响。然而,与年龄匹配的对照组相比,治疗使老年大鼠阴茎组织中的平滑肌水平增加,胶原蛋白水平降低。
基于我们的研究,我们发现肉桂提取物对老年大鼠性功能障碍的治疗有效,因此我们提出了肉桂可能的作用机制,该机制可能是老年大鼠恢复性活动的原因。
