低温保存内生致热原对其致热活性的影响

本实验用家兔全血加精制大肠杆菌内毒素，体外培养提取粗制家兔内生致热原。给大鼠静脉注射复制发热模型，观察了不同温度保存和不同时间保存的ＥＰ对其致热活性的影响。结果表明：４℃保存３天，－４０℃保存３天，７天，３０天和１８０天的ＥＰ与４℃保存１天的ＥＰ比较，其发热第一时相发热峰值和１小时体温反应指数均无显著性差异（Ｐ＜０．０５）。发热第二时相△Ｔ和第二时相１小时ＴＲＩ，在４℃保存３天和－４０℃保存３天，     

现代教学设施在急诊教学中的应用

IMPLICATIONS OF LYMPHOCYTE E ROSETTE FORMATION IN CEREBROSPINAL FLUID AND PERIPHERAL BLOOD

Lymphocyte E rosette formation in cere- brospinal fluid (CSF) and blood samples from 23 patients with different neurologic disorders js investigated. 6 individuals, not diagnosed as having immunopathologic disease with normal CSF, were selected as controls. The percentage of rosette forming cells (RFC) was within the range of 58-78% (mean 66.3+7.6%) which is very similar to the blood values. A very significant correlation between CSF and blood values was observed (p<0.01). However, no evident cor- relation between CSF and blood values (p > 0.05) was found in 16 samples from the remaining 15 patients with autoimmune diseases of the nervous system and neurologic disorders pos- sibly causing immunologic abnormalities. Among 9 patients with autoimmune diseases of the nervous system, 1 case of optic neuritis showed increased RFC values with very high CSF values (86% and then 93%) and no amelio- ration was observed. The RFC values in 5 idiopathic polyradiculoneuritis patients seemed to change with the severity and course of the disease, i.e. patients in the acute stage or who were seriously ill had increased percentages in CSF and/or blood and recovered patients or those with mild illness had values within normal range. Two patients with systemic myasthenia gravis had very low CSF RFC values of 3c70 and 39'70 but l with only ocular symptoms had an increased CSF RFC value of 86%. Among 8 patients with neurologic disorders possibly causing immunologic abnormalities, 1 with viral encephalitis had the highest CSF value of 95'/o and l with glioma of the temporal lobe had an increased CSF value of 85tlo but a 10wered blood value of 32.5%. The authors suggest that not only the abn.ormal RFC values but also the abnorma.l differences between CSF and blood values may be of significance. The evident differences between CSF and blood values in pathologic conditions may be caused by the sequestration of blood-brain barrier. Abnormal rosette forma- tion is considered to be due to changes in cyclic nucleotides (cAMP and cGMP) levels in dif- ferent diseases.
