老年期痴呆患者血中氧自由基反应的相关指标

为探讨氧自由基与老年痴呆发生发展的关系,分别测定了２７例阿尔采默型霉年期痴呆,２７例多发梗塞性痴呆患者和３７例同龄的健康老年人血清中超氧化物歧化酶及其同功酶活性和ＬＰＯ含量。结果显示：ＳＤＡＴ和ＭＩＤ患者的Ｔ－ＳＯＤ,ＣｕＺｎ－ＳＯＤ活性和ＬＰＯ含量均显著高于同龄的对照组,其中ＣｕＺｎ－ＳＯＤ的异常阳性率最高,达５９．３％;Ｔ－ＳＯＤ,ＣｕＺｎ－ＳＯＤ在不同病程的三组间有显著差异。     

Study of the Concentration of Trace Elements Fe,Zn, Cu,Se and Their Correlation in Maternal Serum,Cord Serum and Colostrums

A study of iron, zinc, copper and selenium concentration levels was carried out in three compartments namely, maternal serum (MS), colostrums and cord blood serum (CS) of healthy Indian mothers (n = 42) who delivered healthy normal neonates without any congenital anomalies at Bhabha Atomic Research Centre hospital, Mumbai. Fe, Zn, Cu in maternal serum, cord blood and colostrums were estimated by flame atomic absorption spectrometry while Se was determined by graphite furnace absorption spectrometry. It was seen that there was a significant difference in the level of trace elements in the three compartments. The average levels of Fe in the three compartments were 1,132 ± 519, 2,312 ± 789 and 1,183 ± 602 μg/L while Zn was 514 ± 149, 819 ± 224 and 7,148 ± 2,316 μg/L respectively. Mean Cu values were 1,614 ± 295, 301 ± 77 and 392 ± 174 μg/L respectively while Se values were 70 ± 15, 36 ± 10 and 23 ± 8 μg/L respectively. The results indicated a positive correlation of Fe and Zn concentrations in MS versus CS which were (r = 0.386), (r = 0.572) respectively and Fe levels in MS and colostrums (r = 0.235). A few inter element correlations were found within compartments. Zn and Se showed a negative correlation in both MS (r = −0.489) and colostrums (r = −0.258) while a positive inter correlation of Fe and Zn was seen in MS (r = 0.44) and in CS (r = 0.54). This study gave us an overview of the serum and colostrum values of mother and neonates in Indian population, data of which are scarce.

四种海水养殖鱼类血清转铁蛋白多态性的初步研究

采用PAGE技术测定了大黄鱼、美国红鱼、黑鲷和花鲈四种海水养殖鱼类血清转铁蛋白（Tf）的多态性。研究结果表明：美国红鱼、花鲈、大黄鱼等三种养殖群体Tf有6种表型,受3等位基因控制;黑鲷有9种表型,受4等位基因控制。美国红鱼、花鲈、黑鲷的血清转铁蛋白杂合体基因型均大于纯合体,而大黄鱼的则是杂合体小于纯合体。血清铁浓度：花鲈〉黑鲷〉美国红鱼〉大黄鱼;铁饱和度：黑鲷〉花鲈〉大黄鱼〉美国红鱼。由此推断,黑鲷的耐低氧能力比其他三种海水养殖鱼类强。     

Study of Serum Homocysteine, Folic Acid and Vitamin B12 in Patients with Preeclampsia

The present study was carried out to evaluate the occurrence of association between homocysteine, folic acid and vitamin B(12) in patients with preeclampsia. Fifty preeclamptic patients from gynecology ward were studied for estimation of serum homocysteine, folic acid and vitamin B(12) over a period of October 2007 to June 2010. Serum homocysteine and folic acid, and vitamin B(12) were determined by means of Immulite 1000 analyzer. The statistical analysis of study group of preeclampsia compared with normotensive control group, showed significant alterations in serum homocysteine, folic acid and vitamin B(12) concentrations in preeclampsia. Inverse association between serum homocysteine and folic acid, and vitamin B(12) levels were observed in preeclampsia. The present study found hyperhomocysteinemia and deficiency of folic acid and vitamin B(12) along with increased blood pressure as a risk factor for cardiovascular disease (CVD) in preeclampsia.     

黑龙江依兰始新世植物群的研究

本文报道了黑龙江依兰煤矿早第三系始新统达连河组的上、下两个层位所产的植物化石的区系组成及植物群特征：一个系产于煤层下部的砂页岩中的植物群A，另一个是产于煤层上部油页岩中的植物群B。植物组合共计35科49属52种，其中有蕨类植物2种，裸子植物10种，被子植物40种，其中包括1个新种。对其进行区系成分和叶相分析表明，A段植物群的古植被为北亚热带常绿阔叶和落叶阔叶混生林；B段植物群的古植被为暖温带落叶阔叶林。通过与邻近地区的国内外相应植物群比较及植物群的属种地史分布分析，确定A段植物群的时代为早始新世，B段植物群的时代很可能为晚始新世。两个层位间植物群区系成分的变化，表明始新世我国东北地区发生了较明显的气温下降过程，即古气候发生了由亚热带向暖温带的变化。

The Correlative Study of Serum Pseudo-cholinesterase, Biological Parameters and Symptoms Among Occupational Workers

Cholinesterase is one of many important enzymes needed for acetylcholine hydrolysis. This study aimed to evaluate the serum pseudo-cholinesterase (BuChE) level and its relation to biological parameters (hematological and biochemical parameters) and symptoms among occupational workers, gasoline station worker in Bangkok, Thailand. Our results revealed that the average BuChE level was in normal range, but it had strong relation to hemoglobin (Hb), hematocrit (Hct), blood urea nitrogen (BUN), creatinine (Cr) and serum glutamic pyruvic trans-aminase (SGPT) (Linear regression analysis, p < 0.05, p < 0.05, p < 0.01, p = 0.001 and p < 0.01 respectively). Although, BuChE was not related to white blood cell parameters, but it may exhibit the skin irritation (p = 0.058) of the workers as it showed significant correlation to conjunctivitis and nausea (Pearson’s correlation, p < 0.01 and p < 0.05). In conclusion, this finding may explain that BuChE was significantly related to red blood cells (RBC), liver and kidney functions.     

108例病毒性肝炎患者血清补体的研究

报告１０８例病毒性肝炎患者血清总补体（ＣＨ＿（５０））和Ｃ＿３值的检测结果：急性肝炎的ＣＨ＿（５０）为６８．４±６．１３单位／ｍｌ，Ｃ＿３为１３０．２±６．６７ｍｇ％，均高于正常组（ＣＨ＿（５０）为４８．５±５．７５单位／ｍｌ，Ｃ＿３为１０２±５ｍｇ％），Ｐ＜０．０１；其他类型的肝炎患者组的补体均低于正常组，Ｐ＜０．０１．补体的含量与Ｔ细胞花环（Ｅｔ花环）呈中度相关，与ＧＰＴ呈高度相关，因此测定ＣＨ＿（５０）和Ｃ＿３可作为衡量患者机体免疫功能和判断病毒性肝炎预后的指标之一。     

昆栏树属、水青树属和领春木属花粉形态的研究

昆栏树属(Trochodendron)、水青树属(Tetracentron)和领春木属(Euptelea)是一群 种数少而较原始的被子植物。它们主要分布于我国。 对于它们的系统位置存在着不同的看 法。因此本研究的目的，一方面为讨论系统位置时提供孢粉学的资料，另一方面也可为鉴定化 石花粉提供依据。 从花粉形态看，支持这三个属分别成立三个科。昆栏树属和水青树属花粉具三沟，而木兰科为单槽类型，因此不同意把它们放在木兰科(或目)。领春木属花粉具皱(rugate)，皱膜上具粗颗粒(短条)，如果皱进一步缩短和增加数目，类似于金缕梅科某些属，因此支持ronquist     (1968)把领春木科放在金缕梅目。Hutchinson(1969)把昆栏树属和领春木属放在同一科(昆栏树科)，从形态结构，导管存在与否，染色体数目，这两属差异较大，同时花粉的形态差别也较大，本文不支持这种观点。
