Yizhi capsule (YZC) is a type of traditional Chinese medicine (TCM) developed for treating vascular dementia.〔http://www.wiki86.com/view/3819206.htm Retrieved 2013-03-19〕 ==Studies== A study in rats concluded that Yizhi capsule (YZC) has an action of improving learning and memory disorder, and good protective effect on Aβ25–35 induced neurotoxicity in SD rats.〔 〕 Another study assessed the efficacy of Yizhi capsule (YZC) in treating senile dementia. The results showed that YZC could remarkably increase mini-mental state examination (MMSE) and Hamilton Depression Scale (HDS) marks of patients with vascular dementia. Moreover, YZC improved cerebral blood flow, brain electrical activity monitoring (BEAM) and hemorheological indexes especially for the abnormal case.〔 〕 Another study mentions that the raised score in the revised Hasegawa dementia scales (HDS) demonstrated that the effect of Yi Zhi Capsules (YZC) in treating loss of intellectual function after cerebrovascular diseases was significantly better than that of the drug Piracetam. The study concluded that the data indicate that YZC is a relatively good preparation for prevention of vascular dementia.〔 〕 A Cochrane review in 2009, however, concluded that none of the studies conducted up to that time used methods that could provide strong evidence that the capsules are an effective treatment. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Yizhi capsule」の詳細全文を読む スポンサード リンク
