Acupuncture therapy could normalize both increased light chain K value of IgM and lowered trace element Zn content in patients with Behcet's disease with statistically significant differences,suggesting that acupuncture therapy can elevate humoral immunologic function and improve metabolism of the trace element in these patients.

脂肪乳剂在全合一营养液中的稳定性研究
目的对长链脂肪乳注射液及中伥链脂肪乳注射液,分别配制成各种全合一(All-in-One)营养混合液,进行脂肪乳剂乳粒稳定性的对比研究.方法采用国产脂肪乳注射液、中伥链脂肪乳注射液,分别与氨基酸、葡萄糖、维生素、电解质和微量元素配制成(All-in-One).存放25℃1天,置4℃保存8天后25℃静置1天分别取样.同时用上市的长链脂肪乳注射液与中/长链脂肪乳注射液做平衡对照.用光散射分光光度计、库尔特微粒测定仪测定微粒的大小及其分布,较大粒子占理论总油量的质量百分比.并且测定样品的pH、渗透压等.结果在观察期内上市脂肪乳注射液和中伥链脂肪乳注射液其乳粒分布、乳粒大小、pH值和渗透压均无差别.

AIM To study the change of trace elements in the hair of patients with esophageal carcinoma and the role oftrace elements in its development and progress.METHODS The hair of 60 normal people and 126 patients was collected and was divided into groupsaccording to the patients' pathologic changes. The atomic absorption method and fluorescence method wereused to measure the trace elements of copper, zinc, iron, calcium and selenium.RESULTS Zinc in the hair of various patients: a remarkable difference was found between normal people(182mg· kg 1)and the patients (103- 81.6mg·kg 1) (t = 3.79, P<0.01 Duncan' new multiple rangemethod). There was a certain difference between simple hyperplasia and cancer (t = 3.21, P<0.01 ). As forcopper, a great difference existed between normal people (12.01mg· kg-l) and patients with dysphagia (15.16mg·kg-1) and cancer (17.02-17.15mg·kg-1) (t=2.43, P<0.05). No change of zinc and copperwas observed in cancer patients (t = 1.61, P >0.05). The ratio of zinc to copper increased with thedevelopment of pathologic change. The selenium levels in patients (0.46-0.67mg·kg-1) was below that ofnormal people (l.03mg·kg-1), while iron and calcium levels in the patients decreased with the developmentof pathologic process.CONCLUSION Both zinc and copper play an important role in the pathologic change of esophagealcarcinoma. Zinc and copper in the hair changed with development of the pathologic process. Zinc revealedpositive correlation ( r = -0. 889, P < 0.01 while copper showed negative correlation ( r = 0.921, P < 0.01 ).The ratio of copper to zinc in the hair is of great diagnostic value.

Zinc supplementation can help maintain learning and memory function in rodents. In this study, we hypothesized that zinc supplementation could antagonize the neurotoxicity induced by aluminum in rats. Animals were fed a diet containing different doses of zinc (50, 100, 200 mg/kg) for 9 weeks, and oral y administered aluminum chloride (300 mg/kg daily) from the third week for 7 consecutive weeks. Open-field behavioral test results showed that the number of rearings in the group given the 100 mg/kg zinc supplement was significantly increased compared with the group given the 50 mg/kg zinc supplement. Malondialdehyde content in the cerebrum was significantly decreased, while dopamine and 5-hydroxytryptamine levels were increased in the groups given the diet plemented with 100 and 200 mg/kg zinc, compared with the group given the diet supplemented with 50 mg/kg zinc. The acetylcholinesterase activity in the cerebrum was significantly decreased in the group given the 100 mg/kg zinc supplement. Hematoxylin-eosin staining revealed evident patho-logical damage in the hippocampus of rats in the group given the diet supplemented with 50 mg/kg zinc, but the damage was attenuated in the groups given the diet supplemented with 100 and 200 mg/kg zinc. Our findings suggest that zinc is a potential neuroprotective agent against alumi-num-induced neurotoxicity in rats, and the optimal dosages are 100 and 200 mg/kg.

中国大鲵皮肤、肌肉与骨骼中6种微量元素测定
中国大鲵(Andrias davidianus)简称大鲵,俗称娃娃鱼,隶属于两栖纲、有尾目、隐鳃鲵科,是我国特有的有尾两栖动物,也是世界现存两栖类中体形大、寿命长的古老动物,由于其具有极大的食用、药用、观赏及科研价值,因此滥捕乱猎现象十分严重,导致大鲵野生种群数量锐减,分布范围缩小,我国将其列为Ⅱ类国家重点保护野生动物.

764名儿童五种元素监测结果分析
必需的常量和微量元素在人体内含量虽然不多,但与人的生命和繁衍,保证生长发育和健康成长息息相关,常量和微量元素摄入过量、不足以致缺乏都会不同程度地影响人体的健康;儿童处于生长发育阶段,其体内常量和微量元素的含量对儿童体质发育起着重要的作用.为了解城市儿童体内的常见元素含量并探讨其综合防治措施,对764名儿童进行了3种微量元素(铜、锌、铁)和2种常量元素(钙、镁)检测,现将检测结果报告如下.

中药炮制辅料与微量元素的关系探讨
中药材在炮制的过程中,往往须加入一些辅料,使之符合临床用药的要求.炮制中药用辅料的目的,就是给予一定的外界条件,使中药内在的矛盾,向着有利于防病治病的方向转化.如:有的加入辅料,是为了互相制约,互相促进;有的是为了添加微量元素,增强疗效;有的是为了缓和烈性,改善药性;有的是为了便于加工或制剂等等.
