药用淀粉生产工艺改进研究

用十二烷基硫酸钠或十二烷基磺酸钠与亚硫酸的混合液浸泡玉米，能有效地降低玉米淀粉中的蛋白质含量，较单独用亚硫酸浸泡，所得玉米淀粉的蛋白质含量可分别降低４０％和３５％。

Involvement of IL-1beta in acute stress-induced worsening of cerebral ischaemia in rats.

Stress is known to be one of the risk factors of stroke. Most of the knowledge on the effects of stress on cerebrovascular disease in humans is restricted to catecholamines and glucocorticoids effects on blood pressure and/or development of atherosclerosis. However, few experimental studies have examined the possible mechanisms by which stress may affect stroke outcome. We have used an acute stress protocol consisting of the exposure of male Fischer rats to an acute, single exposure immobilisation protocol (6 h) prior to permanent middle cerebral artery occlusion (MCAO), and we have found that stress worsens behavioural and neurological outcomes and increased infarct size after MCAO. The possible regulatory role of the TNFalpha and IL-1beta was studied by looking at the release of these cytokines in brain. The results of the present study showed an increase in IL-1beta release in cerebral cortex after exposure to acute stress. Brain levels of IL-1beta are also higher in previously stressed MCAO rats than in MCAO animals without stress. Pharmacological blockade of IL-1beta with an antibody anti-IL-1beta led to a decrease in the infarct size as well as in neurological and behavioural deficits after MCAO. In summary, our results indicate that IL-1beta, but not TNFalpha, accounts at least partly for the worsening of MCAO consequences in brain of rats exposed to acute stress.     

Onychopathy in a Patient with Fetal Hydantoin Syndrome

Abstract: Hydantoin is an anticonvulsant drug with several side effects. A teralogenic potential has been suggested. The fetal hydantoin syndrome is an entity that consists of a broad range of morphologic and developmental disorders in children born of epileptic mothers exposed to hydantoin during pregnancy. We treated a girl in whom onychopathy was a monosymptomatic or mild form of this syndrome.     

护生自身练习护理操作的伦理问题及对策

自身练习护理操作就是以护生作为练习对象,相互间在各自身上完成注射、输液等操作练习项目,以达到教学要求[1]。在基础护理的教学中,自身练习对于调动护生的参与感,增加真实感,满足成就感方面起着十分重要的作用。但是,也必须看到在积极效果背后的种种矛盾以及由这些矛盾可能导
