扩散法被动式甲醛个体监测器（Ⅱ型）的研制

介绍了一种基于气体分子扩散原理的被动式甲醛个体采样器，它是在Ⅰ型采样器的基础上完成的。采用甘油（２０％）／偏重亚硫酸钠（０．２５％）浸渍的定量滤纸（φ４２ｍｍ）作为吸收层，空气中甲醛扩散到吸收层上，形成稳定的化合物。采样一定时间后，取出吸收层，洗脱后，用ＡＨＭＴ化学比色法测定所采集到的甲醛。这种采样器的平均采样速率为８３ｍｌ／ｍｉｎ，标准偏差为７．２ｍｌ／ｍｉｎ，与有动力吸收管采样的方法相比较，总不确定度小于±２５％。     

Oral cancer progression and c-erbB-2/neu proto-oncogene expression.

Monoclonal antibody PAb3 to c-erbB-2/neu protein was utilized in the immunoperoxidase staining of 86 human specimens from oral mucosa. These tissue specimens represented a spectrum from 7 normal to 9 simple hyperplasia, 15 mild dysplasia, 14 moderate dysplasia, 20 severe dysplasia and 21 squamous cell carcinoma. Our study indicated that as the cells acquire a more malignant phenotype, there was a progressive increase in neu expression. It also suggested that neu may be involved in the development of oral cancers and that its evaluation in the early stages may assist in the diagnosis and management of oral cancers.     

Serotonergic projections from the midbrain periaqueductal gray and nucleus raphe dorsalis to the nucleus parafasccicularis of the thalamus

By a double-labeling method combining the retrograde tracing of horseradish peroxidase and the immunocytochemical technique, serotonin-like immunoreactive neurons in the midbrain periaqueductal gray (PAG) and nucleus raphe dorsalis (DR) of the rat were observed to send projection fibers to the nucleus parafascicularis of the thalamus bilaterally with an ipsilateral dominance. These serotonin-containing projecting neurons were observed mainly at the middle-caudal levels of the ventrolateral subdivision of the PAG and less at the middle-rostral levels of the DR.     

极低频强磁场对豚鼠听阈的影响

本研究以豚鼠皮层听觉诱发电位反应阈为指标，采用自体或群体对照方法，观察０．１Ｈｚ极低频磁场对豚鼠听力的影响。结果表明，豚鼠经５０ｍＴ（毫特）、４ｈ，１００ｍＴ、４８ｈ及１０ｍＴ、４周暴露后，听阈降低；５０ｍＴ、４８ｈ，２０ｍＴ、４周暴露后听阈无明显变化。提示０．１Ｈｚ极低频磁场对豚鼠听敏度无不利的影响，在某些暴露条件下，听敏度尚有改善。     

超声心动图监测经导管心脏间隔缺损关闭术

应用超声心动图监测，经导管关闭先天性心脏间隔缺损９例。术中监测的主要内容有：（１）确定关闭器在心内的位置；（２）显示残余分流和瓣膜返流；（３）观察房间隔缺损球囊探测的过程。结果表明：超声心动图在显示心内结构、关闭器位置，残余分流和瓣膜流等方面有其独特性，同时可结合声学造影或术中需要进行多方面的监测。     

Good regulation of acupuncture in simple obesity patients with stomach-intestine excessive heat type

In order to investigate the regulatory effect of acupuncture on obesity patients with the Stomach-Intestine Excessive Heat Type, the pre-acupunctureal and post-acupunctural obesity index and biochemical indices of 718 simple obesity patients with Stomach-Intestine Excessive Heat Type were observed. It was showed that the marked weight loss effect was achieved in the cases by acupuncture, and the biochemical indices improved. It suggests that acupuncture had a optimal regulatory effect on the function of nerve, endocrine, digestion and energy metabolism.     

珠子参挥发油的化学成份

利用气相色谱—质谱—计算机联用仪分析了云南省腾冲县产珠子参挥发油的成份,从中鉴定了27种化合物,测定了它们的相对含量,其中有10种倍半萜烯和一种倍半萜醇。

B超,CT与DSA对肝癌介入治疗的指导价值

对１２６列原发性肝癌与３７例转移性肝癌介入治疗前均进行了Ｂ超、ＣＴ与数字减影血管造影（ＤＳＡ）检查。ＤＳＡ显示原发性肝癌多数血供丰富，而转移性肝癌以少血供者为主；ＣＴ显示小病灶的敏感性稍差，病灶的密度和均匀性与血供多少有一定关系，但特异性不高，而病灶的增强次应与血供关系密切，多血供者中９５％有显示的增强效应，少血供者仅占４．７％；Ｂ超所示病灶的回声高低与血供亦有一定关系，但特异性稍差。结果表明，Ｄ
