恶性肿瘤患者血清癌胚抗原放射免疫分析

本文采用放射免疫法测定了144例恶性肿瘤患者血清CEA含量,并以同样条件测定了30例正常人作为对照。结果表明恶性肿瘤患者血清CEA含量显著高于健康人,均值为10.3±4.84ng/ml。不同肿瘤患者血清CEA升高的程度不等,其中以肺癌含量最高为14.7±7.83ng/ml。转移性肿瘤CEA含量高于144例肿瘤的平均水平。术后复发者含量不见下降。癌性胸腹水中CEA含量明显升高。因此,血清CEA的测定对恶性肿瘤的辅助诊断,评价疗效和判断预后具有重要的临床意义。     

胆囊小隆起性病变的诊断及治疗

报告37例胆囊小隆起性病变，其中良性颈变34例，胆囊癌3例。结果：本组23例有临床症状，多表现为反复发作的右上腹疼痛或不适；病灶部位，大小，多少，有无合并胆石及病变性质与临床症状有关；B-us,OCG,CT的诊断符合率例如辚33／37，9／24和5／10（x^2=18.75,P<0.005)。认为对胆囊小隆起性病变的病灶≥10mm，有增大趋势，呈恶性图像，合并胆石或血清CEA升高的病例应及早手术治疗。

Postnatal differentiation and development of the rat epididymis: A stereological study

Postnatal development and differentiation of the rat epididymis was studied in the rat from 15 to 120 days of life using stereological techniques. Both the relative volume (volume density) and absolute volume of the epithelial, interstitial, and luminal compartments in the initial segment, caput, corpus, and cauda epididymides were determined. In all segments the volume density of the epithelial compartment increased between days 15 and 30 before falling to adult values at 45 days in the initial segment (0.476 ± 0.031), at 60 days in the caput (0.258 ± 0.028) and at 90 days in the corpus (0.245 ± 0.007) and cauda (0.140 ± 0.004). The relative volume of the interstitium decreased, whilst that of the lumen increased over the same period with adult values being achieved earlier in the proximal segments than in the distal segments. In contrast to volume fraction the absolute volume of all compartments in all segments increased from day 15 to day 90. Between 90 and 120 days the absolute volumes of compartments in the initial segment and caput showed little volume change. All compartments in the corpus and cauda showed significant increases in volume over the same period. A similar pattern of development was observed with respect to the surface area of both the luminal and basement membrane aspects of the epithelium; surface area per unit volume (surface density) in all segments reached adult values at approximately 60 days, whilst the increase in absolute area of the surfaces ceased at 90 days in the initial segment and caput and continued to 120 days in the corpus and cauda. The total length of the epididymal tubule showed the same pattern with no increase in length apparent in the initial segment and caput after 90 days. Length however continued to increase in the corpus and cauda between 90 and 120 days. Tubule and luminal diameter reached their definitive values in the initial segment on day 60 but continued to increase until day 90 in the distal segments. Epithelial height increased between 15 and 30 days in all segments; in the caput, epithelial height was greatest on day 30 before decreasing slightly; and in the corpus and cauda maximal epithelial height was observed on day 45 decreasing to stable values on day 60 and 90, respectively. All the data is consistent with a proximal to distal differentiation and development of the epididymis with growth continuing in all segments after the establishment of the definitive architecture. Growth of the distal segments continued after its cessation in the proximal segments. © 1994 Wiley-Liss, Inc.     

钡离子(Ba~■)诱发心室肌细胞自发电活动的实验

用心肌细胞跨膜电位记录,证实高浓度Ba~■(4mol/L)可诱发豚鼠心室肌自发电活性,这种自发电活性主要来自延迟后除极电位(DAD)及触发活动,且可被维拉帕米(异搏定)阻断,提示DAD的产生与钙离子内流有关。     

北京地区361名孕妇乙型肝炎流行病学研究

从1985年4月到1986年4月对361名孕妇进行的乙型肝炎流行病学横断面研究以及196名产妇一年随访研究的结果表明,361例孕妇的HBsAg阳性率为2.5%,抗-HBs阳性率为23.8%,抗-HBc阳性率为22.1%,HBV总感染率为31.3%;抗-HBs阳性、抗-HBs和抗-HBc共存阳性者占总阳性者的76.1%,说明人群感染HBV后大多产生了免疫力.1986年4月复查了196例产妇,133名在1985年HBV标记阴性者中有6人获得了HBV标记,HBV新感染率为4.5%;1例为急性乙型肝炎病人,5例为亚临床感染.HBV新感染者的感染途径不明,但医源性传播不能排除.1986年检查的148对夫妇中,男性HBsAg阳性率是女性的3.1倍(6.1%对2.0%),男性单独抗-HBc阳性率是女性的2.3倍(6.1%对2.7%),抗-HBs、抗-HBs和抗-HBc共存以及HBV感染率男女性间都无显著差异.
