马克思、恩格斯论性爱、婚姻和家庭(续三)

2婚姻科伦12月18日。莱茵报对于离婚法草案采取了完全独特的立场,可是直到现在为止,还没有任何方面向我们证明莱茵报的立场是没有根据的。莱茵报同意这一草案,因为它认为现行的普鲁士婚姻法是不合乎伦理的,目前离婚理由的繁多和轻率是不能

银杏叶浓缩口服液药理作用的研究

目的：探索银杏叶浓缩口服液（缩写Ｇ．Ｃ．Ｌ）的抗脑缺氧、抗脑缺血药理作用。方法以生理盐水组为空白对照,进行药理实验方法的平行比较研究。结果Ｇ．Ｃ．Ｌ能延长断头小鼠张口喘息时间及ＫＣＮ所致小鼠翻身反射消失时间,可降低结扎两侧颈总动脉所致脑缺血大鼠脑水份的含量,能抑制大鼠脑组织中过氧化脂质的生成。结论提示该口服液具有抗脑缺氧、抗脑缺血及改善脑循环的作用。     

An epidemiological study to identify the risk factors with two different types of controls in high-grade cervical lesions including invasive cancer

A multidisciplinary study on pre-cancerous and early cancerous lesions of uterine cervix was carried out at our Institute from which the subjects (cases and one group of control) for the present study were selected with the objective to identify the possible risk factors related to high-grade cervical lesions including invasive cancer through an epidemiological study by selecting two different types of controls and to assess the feasibility whether the cancers of other organs could be taken as controls at the same time studying the risk factors associated with cervical cancer. One group of control was women with negative Pap smear and second group of control was the women with breast cancer but negative Pap smear. A total of 100 biopsy-proven cases of high-grade cervical intraepithelial lesions and Invasive cancer were recruited. The results of the study show that some of the risk factors associated with the cervical cancer get exaggerated when breast cancer cases were used as controls because risk factors of both cancers are opposite to each other. So it is concluded that in order to remove any bias, normal hospital controls or controls selected from multiple cancers should be taken to study the risk factors involved in cervical carcinogenesis.
