衰老学

In the in vivo study, 100 ICR mice were randomly assigned to 5 groups after paired by body weight as following: Group N (negative control group, peritoneally injected by saline daily); Group C (positive control group, peritoneally injected by D-galactose and saline daily); Group L, M, and H (peritoneally injected by D-galactose and intragastric administered with TP at 100, 200, 400 mg/day, respectively). Mice were sacrificed for histology and biochemistry studies after 8 weeks.

在动物体内实验中，选择清洁级ICR纯系小鼠100只，按体质量随机分为5组：阴性对照组每天腹腔注射生理盐水，其余4组每天腹腔注射120 mg/kg D-半乳糖以建立小鼠衰老模型，同时阳性对照组每日以生理盐水灌胃，L、M、H组分别以每日100、200、400 mg/kg TP灌胃。8周后处死小鼠，获取心肌标本进行组织学研究和生化检测。

Purpose: Explore the histological characteristics of aging muscle cell.

目的：探讨衰老大鼠肌细胞的组织学特征。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
