免疫荧光法与 Giemsa 氏法检测沙眼衣原体的比较

本文用免疫荧光法与 Giemsa 氏法检测明显沙眼患者,两法阳性率相差无几。但在临床肉眼观察认为正常时,其阳性率分别为24.77%及11.58%(P<0.05),差异有显著意义,表明免疫荧光法检测早期沙眼较 Giemsa 氏法敏感。临床认为正常眼,经实验室检查25.56%为阳性,说明开展沙眼的实验室诊断是必要的。

广州地区新生儿输血传播病毒感染状况

目的 探讨广州地区新生儿输血传播病毒（TTV）感染率及基因型。用PCR对835例正常新生儿脐血标本进行TTVDNA扩增，对9例TTVDNA阳性PCR扩增产物进行克隆和测序。结果 18例新生儿脐血检出TTVDNA，阳性率2．2％。9例被测序的TTVDNA阳性标本核苷酸序列与日本分离株的同源性为86．8％－96．7％。结论 新生儿存在先天性TTV感染。TTV广州株与日本株具有相似的基因型。     

A PRELIMINARY STUDY OF THE ACTION OF MALE HOR MONE ON HIGH DENSITY LIPOPROTEIN-CHOLESTEROL

Plasma testosterone and estradiol are determined in 72 patients with abnormal high density lipoprotein. cholesterol (HDL-C) and high density lipoprotein cholesterol/total cholesterol (H/T) ratio values, and in 72 randomly chosen males with normal HDLC and H/T values. The results showed that plasma testosterone levels in the groups with abnormal HDL-C and H/T were obviously lower than those in the controls. Statistically significant differences were found in all the abnormal groups in comparison with the controls (P0.20). Testosterone levels lowered further with increasing age in the groups with abnormal HDL-C and H/T., the most obvious drops were in the groups around 56 years of age (P<0.005). The data indicate that male hormone deficiency may reduce HDL-C and H.'T and facilitate the process of atherosclero_is. Therefore, it seems rational to treat such patients with male sex hormone preparations or to use the traditional Chinese medicines which strengthen Yang (maleness) in a new attempt to treat and prevent CHD.

给药系统进展概述(下)

二、靶向给药系统(Targeting Drug Delivery System) 目前药物治疗全身性疾病是通过各种途径给药,达到一定的血药浓度分布于全身而产生治疗作用,这种治疗方法最大的缺陷是缺乏选择性。如某些疾病只局限于某个部位或器官,则到达的药物仅一小部分,大部分药物未发挥作用,某些强烈的药物往往在起治疗作用的同时产生毒副作用,严重地影响药物的治疗价值。靶向给药系统可提高药物
