正常人体多毛部位皮肤雌激素受体的比较研究

应用直接荧光组化法对１０例正常男性头皮、眉部、胡须、腋部、阴部皮肤作比较研究。结果显示皮肤和附属器均有雌激素受体（ＥＲ）存在，而部位不同，含量各异。阻断对照：阻断率５０％～９０％。进一步证实皮肤是雌激素靶器官之一。

Additive effects of earthworm extract with HpD-laser on the enhancement of reactive oxygen production and the inhibition of[~3H]—thymidine.uptake in mouse ascitic tumor cells

The effects of combined use of earthworm extract(912)and HpD-laser on the produc-tion of reactive oxygen and the biosynthesis of DNA in S_(180) tumor cells were studied throughchemiluminescence measurement and[~3H]-TdR incorporation assay.The results showed that as com-pared with the control,the intensity of chemiluminescence emitted by tumor cells treatedsimultaneously with 912 and HpD-laser was enhanced more than ten-folds,while that treated with912 or HpD-laser alone was increased only 2～4 folds.The[~3H]-TdR incorporation into tumorcells of the former group was inhibited upto 74.1%,and that of the latter groups decreased onlyby 42.2% and 40.0%,respectively.In accordance with these biochemical changes,the ultrastructuraldamage of tumor cells of the former,combinedly treated group appeared to be the most serious.This suggests an additive effect of 912 with HpD-laser on tumor cells.In addition,if free radicalscavengers,such as catalase and superoxide dismutase,were added to the reaction systembefore chemiluminescence assay,the luminescent enhancement effect mentioned above was dramaticallyalleviated,implying the presence of O_2~ and H_2O_2 in the system.Therefore,as to the toxic effecton tumor cells,912 and HpD-laser are not only additive in efficiency,but also similar in theunderlying mechanism of action.     

男性肝硬化患者血清睾丸酮、雌二醇水平

本文观察了80例男性肝炎后肝硬化患者。检测了血清睾丸酮（T），雌二醇（E2）水平及E2／T比值的变化。与正常对照组及脑血管意外对照组进行了统计比较，发现E2及E2／T比值升高，T值降低2与对照组间比较均有显著差异，但肝硬化各组间无明显差异。文中分析了检测结果并探讨了与性功能变化的关系。认为性功能降低可能是由于血清睾丸酮水平降低所致。

老年冠心病患者的动态心电图观察

对97例老年冠心病患者进行动态心电图观察,共检出97例患者缺血性ST段发作347阵,心率减慢时发生缺血48例(49.5％),全程无症状者75例(77.4%),缺血时有无胸痛与ST段下降程度无必然联系。     

Factors associated with hypertension in Nigerian civil servants

BACKGROUND. Study of hypertension in segments of West African populations in transition toward Westernization may lead to better understanding of the high risk for hypertension among Westernized blacks. METHODS. Five hundred fifty-nine urban civil servants, ages 25-54, were recruited from six ministries of Bendel State, Nigeria. Blood pressure, physical measurements, urinary protein and glucose, fasting blood glucose, and demographic data were collected at the workplace. Subjects were classified as senior staff (professionals or administrators) or junior staff (non-administrators). RESULTS. Among 172 male senior staff, the age-adjusted rate of hypertension (diastolic blood pressure > or = 90 mm Hg, systolic blood pressure > or = 140 mm Hg, or on an antihypertensive medication) was 43% and occurrence rose dramatically from 21 to 63% across age groups 25-34 to 45-54, respectively. Among 266 male junior staff, the age-adjusted rate of hypertension was 23%, and occurrence did not rise with age. Logistic regression showed that body mass index (kg/m2), age, alcohol drinking, and being senior staff were all independently related to hypertension in men. On the other hand, the age-adjusted rate of hypertension in 121 women was 20% and was significantly related only to body mass index. CONCLUSION. Male urban civil servants appeared to have a risk for hypertension similar to that of U.S. black males. Age, body mass index, alcohol drinking, and other unidentified factors related to higher socioeconomic status were strong determinants of hypertension in this population.     

肝硬化门静脉高压症内毒素血症的治疗

目的　研究肝硬化门静脉高压症 (PHC)病人内毒素血症治疗方法及其对预后的影响。方法　选 3 6例 PHC择期手术病人 ,随机分为治疗组 (n=18)和对照组 (n=18) ;治疗组入院后除保肝、纠正低蛋白血症及贫血等术前一般准备外 ,另行每日服用中药茵陈小承气汤和稀生理盐水碘伏液灌肠术等 ,对照组行 PHC的常规术前准备。观察两组病人术前血浆内毒素(PE)水平变化和术后全身炎症反应综合症 (SIRS)、多脏器障碍综合症 (MODS)的发生率等。结果　入院时所有 PHC病人均存在不同程度的内毒素血症。经过术前准备 ,治疗组术前 PE水平由 0 .13 9± 0 .0 2 2 Eu/ m l降至 0 .12 2± 0 .0 2 4 Eu/ m l(P<0 .0 5 ) ,对照组则下降不明显 (P>0 .0 5 )。术后治疗组的 SIRS、MODS的发生率和死亡率分别为 :11.1%、5 .6%、0 % ;对照组则分别为 :4 4 .4 %、2 7.8%、5 .6%。术后胃肠功能的恢复时间 :治疗组 (78.3± 2 1.2 h)比对照组 (13 8.4± 4 2 .5 h)显著缩短 (P<0 .0 0 1)。结论　应用茵陈小承气汤结合稀生理盐水碘状液清洁胃肠道 ,可以降低 PHC病人由于细菌易位所致的内毒素血症以及其对机体的损害 ,从而减少 PHC病人术后 SIRS、MODS的发生率及死亡率     

在音乐缭绕中痊愈

你是否曾经因为它血脉贲张浑身发抖过．你是否因为它心潮起伏热泪盈眶过？如果这世界上没有它．你怕么？当天堂的圣歌响起．即使面对死亡．你也无所畏惧，它以它温柔的手．抚平你心里和肉体的伤……它让你不痛。[编者按]
