陕西省健康人群脊髓灰质炎免疫屏障的评价

为了对陕西省近 10年脊髓灰质炎 (脊灰 )的免疫状况做出科学的评价 ,在地理特点不同、经济发展程度各异的 3个地区采集 0～ 39岁健康人群血标本 86 6份测定脊灰抗体。脊灰Ⅰ、Ⅱ、Ⅲ型中和抗体阳性率分别为96 88%、98 0 4%、92 73%,几何平均滴度 (GMT)分别为 1∶2 5 9 30、1∶10 3 6 9、1∶5 2 6 9。表明通过口服脊灰疫苗的常规免疫和强化免疫 ,陕西省健康人群对脊灰已形成牢固的免疫屏障。     

选米有方 吃走慢性病

中国自古以来确信五谷为养的原则，现代营养科学也证实，只有吃足够多的复杂碳水化合物，才能维持长期的健康。对于中国人来说，米饭，就是复杂碳水化合物的主要来源之一。它不仅要为人体提供营养，也要为人体养身防病做出贡献。     

规范监护病区管理提高医疗服务质量

外科重症监护病区(SuegeryIntensiveCareUnit简称SICU)是外科各类危重、疑难及抢救病例集中抢救治疗观察的病区。仁济医院东部SICU病区拥有全套先进的生命抢救监测仪器,设置床位10张,并拥有一支技术精湛、业务过硬、工作极端负责的医疗队伍。仁济医院东部现有11个手术科室,约400张床位,平均每月收治危重疑难病例约70～80例,90%病例经SICU抢救观察治疗后转入各相应病区。期间,除了合理的抢救治疗,还存在着病区床位运转流动的程序管理。病区运转初期,各手术科室存在着以本科利益为重为大的思想,缺乏SICU工作的整体概念,所以出现了以下…     

肾血管平滑肌脂肪瘤2例报告

肾血管平滑肌脂肪瘤的名称甚多,有肌脂肪瘤,肌血管瘤,良性动脉平滑肌瘤,错构瘤和血管平滑肌脂肪瘤等,1951年后常用血管平滑肌脂肪瘤。本病较少见,占肾肿瘤的1～12.7％。复习国内外文献,自1880年Bourneville首先报告到1986年国外报道了602例,国内也有100例左右。因本病很少遇到,认识不足,误诊率极     

南昌地区秋冬季婴幼儿腹泻的病原学研究

近年国内外许多学者证实婴幼儿秋、冬季腹泻的主要病原是人轮状病毒。我们于1981年12月至1984年12月收集214例发病的有关标本进行病毒病原的研究。现报告如下: 临床资料:214例中住院病例160例,门诊54例,男154例,女60例,年龄最小的2个月,最大的3岁;6～18个月婴儿最多。11月及12月发病者160例,腹泻粪便多呈稀水样及蛋花样(81.7%)。黄色均未检出脓细胞或红细胞。40例粪便细菌培养阴性。     

IS THE SEVERITY OF OSTEOSCLEROSIS OF FLUOROSIS PROPORTIONAL TO THE DOSE OF FLUORIDE INTAKE?

Histomorphometric study was made on a series of sections of undecalcified epiphyseal femoral specimens from rats with experimental fluorosis. The results revealed osteosclerosis in Group A (5 ppm) being more severe than that in Group B (25 ppm) With the increase of fluoride dose, the parameters fell down instead of increased in parallel. There is seemingly a threshold over which osteosclerosis in fluorosis becomes less severe. In contrast to Bely's conclusion the authors proposed that, fluoride toxi- city, besides decreasing the number of osteoblasts, may also activate the osteoblasts. The number of osteoblasts may be increased with relative lower dose of fluoride also. The net outcome is the in crement in bone volume. When toxic dose of fluoride is higher enough (higher than the proposed threshold), however, the number of osteoblasts and its activity are inhibited. So are the osteocytes. This interpretation may be the cytological basis for osteosclerosis in the experimental fluorosis.     

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.
