Efficacy and Safety of Pueraria lobata Extract in Gray Hair Prevention: A Randomized,Double-Blind,Placebo-Controlled Study

Background

Graying of hair-a sign of aging-raises cosmetic concerns. Individuals with gray hair often look older than others their age; therefore, some dye their hair for aesthetic purposes. However, hair colorants can induce many problems including skin irritation, allergic reaction and hair-breakage.

Objective

This randomized, double-blind clinical trial was performed in order to examine the effects of APHG-1001, a compound including an extract from Pueraria lobata, on graying hair.

Methods

A total of 44 female subjects were randomly treated with either APHG-1001 or placebo twice daily for 24 weeks. Using the phototrichogram analysis, a count of newly developed gray hair was estimated. Investigator assessment and subject self-assessment were also performed in order to evaluate the efficacy of the compound.

Results

The mean number of newly developed gray hair at 24 weeks was 6.3/cm² in the APHG-1001 group and 11.4/cm² in the placebo group; the difference was statistically significant (p<0.05). However, the investigator assessment and subject self-assessment did not show any significant change in the gross appearance of hair grayness by the end of the study. No severe adverse events in either group were observed. Moreover, the incidence of adverse events did not differ between the groups.

Conclusion

This clinical trial revealed that APHG-1001, which contains an extract of P. lobata, could prevent the development of new gray hair without any remarkable adverse effects. Thus, it can be considered as a viable treatment option for the prevention of gray hair.

目的:观察葛根汤加减配合五步手法治疗神经根型颈椎病的临床疗效。方法:将2015年7月—2016年1月就诊于本院的132例患者随机分为对照组和观察组,每组各66例。对照组给予葛根汤加减,观察组在对照组治疗基础上根据患者患病部位给予相应五步手法治疗。比较两组患者的临床疗效、相关功能评分、机体疼痛评分等相关指标的变化情况。结果:观察组有效率为86.36%,对照组有效率为68.18%,两组患者临床疗效比较,差异具有统计学意义(P0.05)。治疗后两组患者相关功能评分和机体疼痛评分较治疗前明显改善,且观察组优于对照组,差异具有统计学意义(P0.05)。结论:葛根汤加减配合五步手法治疗神经根型颈椎病疗效显著。     

Puerarin: A Review of Pharmacological Effects

Puerarin is the major bioactive ingredient isolated from the root of the Pueraria lobata (Willd.) Ohwi, which is well known as Gegen (Chinese name) in traditional Chinese medicine. As the most abundant secondary metabolite, puerarin was isolated from Gegen in the late 1950s. Since then, its pharmacological properties have been extensively investigated. It is available in common foods and is used in alternative medicine. It has been widely used in the treatment of cardiovascular and cerebrovascular diseases, diabetes and diabetic complications, osteonecrosis, Parkinson's disease, Alzheimer's disease, endometriosis, and cancer. The beneficial effects of puerarin on the various medicinal purposes may be due to its wide spectrum of pharmacological properties such as vasodilation, cardioprotection, neuroprotection, antioxidant, anticancer, antiinflammation, alleviating pain, promoting bone formation, inhibiting alcohol intake, and attenuating insulin resistance. However, the direct molecular mechanisms and targets remain unclear. This review provides a comprehensive summary of the pharmacological effects of puerarin.

葛根芩连汤临床应用及实验研究进展

葛根芩连汤具有解表清里之效,主治邪热下利。临床应用指征主要是:①身热下利、肛门灼热、大便不爽或臭秽难闻,甚或脓血便,小便色黄等肠道湿热者;②脘腹胀满、消谷善饥、头身困重、四肢倦怠、口黏、口渴、牙龈肿痛、口舌生疮等脾胃湿热者;③舌红苔黄腻,脉滑数或濡数者。现阶段虽然对葛根芩连汤的研究已不断深入,但仍有不足,比如目前已有大量动物实验研究证明葛根芩连汤可改变炎性因子水平,改善炎性反应,但相关临床研究较少,今后还需加强临床研究,为葛根芩连汤的临床应用提供更多客观依据。

肢体缺血再灌注致兔肺组织损伤及葛根素的干预作用

目的观察肢体缺血再灌注致兔肺组织损伤时抗氧化系统的变化,细胞凋亡数、Bc l-2和Bax蛋白表达,及葛根素的干预作用。方法健康家兔60只,随机分3组:A组(n=20)为假手术组,B组(n=20)为缺血再灌注组;C组(n=20)为葛根素治疗组。实验结束时,取肺组织测定超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-PX)、黄嘌呤氧化酶(XOD)活性和丙二醛(MDA)、一氧化氮(NO)含量,同时计算肺系数及进行肺病理学检查,应用原位缺口末端标记技术(TUNEL)和免疫组织化学方法,观察肢体缺血4h再灌注4h肺脏细胞凋亡数及Bc l-2和Bax蛋白的表达。结果肢体缺血4h再灌注后4h肺组织SOD、GSH-PX活性和NO含量显著下降,XOD活性和MDA含量明显增高,肺系数升高,肺组织病变明显。葛根素的干预治疗可明显缓解上述变化。假手术对照组肺脏见极少量凋亡细胞,缺血再灌注组、葛根素治疗组肺脏均可见大量凋亡细胞,但葛根素治疗组凋亡细胞数比缺血再灌注组明显减少。假手术对照组肺脏组织Bc l-2呈阳性表达,基本未见Bax蛋白表达,其余2组可见大量肺脏组织出现Bc l-2和Bax蛋白阳性表达,但葛根素治疗组肺脏的Bax蛋白阳性表达明显较缺血再灌注组减少。结论家兔肢体缺血再灌注后,肺抗氧化功能下降、肺脏细胞凋亡增多及Bc l-2、Bax蛋白表达上调,葛根素的干预治疗对这种肺损伤有明显的保护作用。
