产色素非O1群霍乱弧菌的发现及其实验研究

１９９４年６月自饮用水源中分离到４株产色素的革兰氏阴性弧菌，运动活泼似流星样．经形态学、培养特性、生化学和血清学方面的系统鉴定，均符合非Ｏ１群霍乱弧菌定义．因该菌在营养琼脂、硷性胆盐琼脂和血琼脂上培育后产生水溶性褐色色素，故被正式命名为产色素非Ｏ１群霍乱弧菌ＶＢＯ８型和ＶＢＯ３８型．     

胃肠道生理功能与脑-肠相关及病理生理学之关联性 四、香草类受体-降钙素基因相关肽-一氧化氮系统在消化道管腔内酸感知结构中的作用

大鼠实验证明 ,十二指肠粘膜之酸感受性血流增加与粘液分泌系介辣椒辣素 (ｃａｐｓａｉｃｉｎ)感受性知觉神经而实现 ,其机制为该神经表达之香草类受体 (ｖａｎｉｌｌｏｉｄｒｅｃｅｐｔｏｒ,ＶＲ)起酸传感器 (ａｃｉｄｓｅｎｓｏｒ)作用 ,同上皮细胞之离子转运(ｉｏｎｔｒａｎｓｐｏｒｔ)功能联合作为感知管腔内酸性状态的酸感知途径 (ａｃｉｄｓｅｎｓｉｎｇｐａｔｈｗａｙ)而实现的。近年研究认为 ,这一机制可能存在于整个消化道粘膜。可以说 ,消化管粘膜一方面品味着管腔内的酸度 ,一方面又进行着监视作香草类受体 (ＶＲ)的临床应用研究…     

克山病病区玉米及酱块对大鼠心肌损伤的实验研究

Objective To investigate the myocardial damage in rats fed with corn from Keshan disease area added with bean puree. Methods Male Wistar rats were randomly divided into 3 groups according to their body weights, and fed with corn, corn from Keshan disease area added with bean puree, corn from non-endemic area. The GSH-Px activity of vena cardalis blood was examined in 1 and 3 months, rats were sacrificed after being fed for 6 months to examine the heart changes with HE stain. Results The three groups of GSH-Px activity were different in 1 and 3 months respectively(F=23.60,72.46, all P<0.01); GSH-Px activity was (181.58±22.15), (44.76±28.59)U/L in rats fed with corn, was (195.03±17.66), (30.38±3.35)U/L in those fed with corn added with bean puree from Keshan disease area, lower than the group fed with corn of non-endemic area[(340.90±95.42), (125.17±13.64)U/L, all P < 0.01]. But the difference of GSH-Px activity between simple corn group and corn adding bean puree groups of Keshan disease area was not obvious(P>0.05). Myocardial damage incidence of the three groups was 3/9,1/9,2/7. Difference among three groups did not have statistical significance(χ2=1.33, P> 0.05). Conclusions Only corn from Keshan disease area may induce myocardial damage pathology change. Adding bean puree into corn does not increase damage.     

家庭模式病房在老年慢性病患者中的应用

我科多年来对老年慢性病患者采用以家庭的形式设立病房,不仅保障了对患者及时有效的治疗,在提高患者的生活质量上,也收到了良好效果。1 对象与方法1.1 对象 选择2001年1月～2002年12月住院的86例老年慢性病患者。家庭模式病房病例30例,男27例,女3例,年龄65～89岁,平均72岁。普通病房病例56例,男50例,女6例,年龄66～90岁,平均71岁。两类病房患者性别、年

营造舒适居室环境

人的体温是恒定的，这是保证正常新陈代谢的重要条件。据生理学家研究，人生活环境的温度如果超过体温调节中枢所及的范围（室温３６℃以上），人体内温度就要升高，新陈代谢就受到影响，会出现食欲不振、呼吸增快、头晕眼花、心跳加快、周围血管扩张、血压先升高后降低等症状。冬天因人体适应高温能力差，只要室温超过２３℃，即可出现不适症状。若较长时间内不能改变，则可使人体代谢机能下降，出现精神不振、头昏脑胀、记忆力减退、思维迟钝、夜间失眠等症状，工作与学习效率明显下降。经过多年的临床实践与研究，专家们认为夏天室内高温…
