新疆出血热病毒与流行性出血热病毒的生物学特性比较

本文通过免疫荧光(IF)和电镜(EM)技术对新疆出血热(XHF)及流行性出血热(EHF)病毒的生物学特性在Vero E_6及LLC-MK_2两株传代细胞上进行了比较。两种病毒感染两株细胞后免疫荧光染色有两种不同的荧光形态特征,两种病毒对细胞的敏感性明显不同,XHF病毒在LLC-MK_2细胞上感染后6～8天可出现明显的细胞病变,而EHF病毒感染此细胞后则不引起病变。电镜观察到两种病毒在LLC-MK_2细胞中都能形成与布尼病毒相似的形态特征。     

农民工结核病健康教育效果评价

目的 探讨开展结核病健康教育对提高农民工相关知识知晓率和态度正确率的作用.方法 对重庆市南岸区农民工进行结核病相关知识的健康教育,教育方式是由专科医生进行专题讲座.健康教育讲座前后在同一现场统一发放问卷,并当场收回,对教育前后农民工的结核病相关知识作一一配对比较.结果 调查15项内容,其中有14项内容教育前后有显著性差异.教育前农民工结核病知识知晓率为67.5%,教育后知晓率为99.5%;正向态度报告率从教育前的44.1%提高到60.1%.结论 健康教育能提高农民工防治结核病知识知晓率和态度正确率,此方法值得推广.

Polymer strength and chain conformation

It is found that the expected maximum strength of polymers is not proportional to the number of polymer chains per unit area. Under uniaxial stressing only part of polymer chains, i.e., overstressed chains, contribute to the strength of the polymer. The number of overstressed chains obtained here for some polymers is consistent with the results of electron paramagnetic resonance and stress-Fourier-transform IR measurements: (a) Polymers with all-trans conformation of their chains have more overstressed chains than those with helix conformation; (b) in the case of polymers with helix conformation, those with smaller side groups have more overstressed chains. Under uniaxial stress, the polymer chains change their conformation from gauche to trans which results in a relief of stress. Polymer with helix conformation thus have less overstressed chains and, hence, lower strength than polymers with all-trans conformation.     

Cultural perspectives and current consumption changes of cooked rice in Korean diet

Cooked rice is a staple food for Koreans which provides more than 60% of daily required energy. In 1960''s, Koreans ate 600 g-800 g of cooked rice per meal and the energy obtained from cooked rice was almost more than 80% of the daily intake of energy. However, as the economy of Korea improved, the major industry has been shifted from agriculture to various manufacturing industries and the export of those products has been increased thus increasing the national income but decreasing the farming population and thus rice consumption have been decreased. It has been said that the decreased rice consumption is caused solely by decreased farming population but it can also be said that the decreased farming population is caused by decreased rice consumption.As the national income increases, the type of foods people consume have become diversified. Various processed foods such as convenience food or ready-to-eat food have been widespread, which are mostly made of wheat flour rather than rice.
