The CLDN5 locus may be involved in the vulnerability to schizophrenia.

The present study was designed to detect three single nucleotide polymorphisms (SNPs) located on 22q11 that was thought as being of particularly importance for genetic research into schizophrenia. We recruited a total of 176 Chinese family trios of Han descent, consisting of mothers, fathers and affected offspring with schizophrenia for the genetic analysis. The transmission disequilibrium test (TDT) showed that of three SNPs, rs10314 in the 3'-untranslated region of the CLDN5 locus was associated with schizophrenia (chi(2) = 4.75, P = 0.029). The other two SNPs, rs1548359 present in the CDC45L locus centromeric of rs10314 and rs739371 in the 5'-flanking region of the CLDN5 locus, did not show such an association. The global chi-square (chi(2)) test showed that the 3-SNP haplotype system was not associated with schizophrenia although the 1-df test for individual haplotypes showed that the rs1548359(C)-rs10314(G)-rs739371(C) haplotype was excessively non-transmitted (chi(2) = 5.32, P = 0.02). Because the claudin proteins are a major component for barrier-forming tight junctions that could play a crucial role in response to changing natural, physiological and pathological conditions, the CLDN5 association with schizophrenia may be an important clue leading to look into a meeting point of genetic and environmental factors.     

The epidemiology and surveillance of blood lead in Taiwan (R.O.C.): A report on the PRESS-BLL project

 To monitor the lead hazards in industries and to investigate the prevalence of elevated blood lead levels (BLLs) in lead-exposed workers, a lead surveillance system (PRESS-BLLs) has been established and operated in Taiwan, Republic of China, since July 1993. A cohort of lead-exposed workers who received a periodic annual health examination at 55 accredited hospital laboratories was constructed. A total of 9807 separate BLL measurements were reported to the system in 1994. The mean BLL was 15.8 μg/dl in male workers and 11.6 μg/dl in female workers. The mean BLL of lead-exposed workers was significantly (P<0.05, z-test) higher than that of the general Taiwanese population (8.6 μg/dl for males and 6.7 μg/dl for females). In addition, the BLLs of 983 (10.0%) workers exceeded the regulatory action level (40 μg/dl for males; 30 μg/dl for females). The workplaces and homes of 57% of the workers with elevated BLLs were thoroughly investigated to determine the sources of lead contamination. These actions identified the causes of elevated BLLs and set up strategies to reduce workers’ lead exposure. The establishment of this occupational lead surveillance system represents a method for monitoring of lead hazards from occupational and environmental settings to prevent lead poisoning. The information acquired from the system can help in the setting up of a priority of prevention and the development of control measures. It is also useful for further monitoring of changes in the BLLs of the lead-exposed-worker cohort. The Health Department of Taiwan can use this information to evaluate the effectiveness of current industrial hygiene practice. Subjects with elevated BLLs have been medically treated and placed on long-term follow-up for sequelae. Received: 2 September 1996/Accepted: 29 November 1996     

Use of the SADP for measurement of attitudes of Chinese dental students and dental surgery assistants toward disabled persons

The purpose of this study was to determine the attitudes of Chinese dental students and dental surgery assistants toward disabled persons using the Scale to Determine Attitudes Toward Disabled Persons, the SADP. A group of 99 Hong Kong University psychology students, 50 male and 49 female, was used as the control and to determine the internal consistency and reliability of the Chinese version of the scale. A group of 4th year (n = 25) and a group of 3rd year (n = 46) dental students and a group of in-house dental surgery assistants (n = 86) at the Prince Philip Dental Hospital, Hong Kong, were asked to complete a Chinese translation of the SADP. Results showed that there was no significant difference between attitude scores of 3rd and 4th year dental students (p = 0.06). There was a significant difference in attitude scores between dental students and the dental surgery assistants (p < O.OOl), with those of dental students being lower. In the control group, there was no significant difference between female control and dental surgery assistant scores (p = 0.289). There was a significant difference between dental students and male control scores (p < 10⁶). Not only did the dental students score lower than the dental surgery assistants, but they also scored significantly lower than a group of non-dental students of the same University.     

大鼠脊髓缺血再灌流时脊髓神经元对躯体和内脏传入刺激的反应

５０只大鼠用乌拉坦麻醉，箭毒制动。通过阻断腹主动脉血流以模拟腰段脊髓的局部缺血和再灌流损伤，玻璃微电极记录Ｌ２节段脊髓单位放电（ＳＣＵＤｓ），观察缺血再灌流时脊髓神经元对腓神经刺激（ＰＮＶ），内脏大神经刺激（ＶＬＮＶ）及两者同时刺激（ＳＶ）的反应。结果在缺血前所记录的１３３个自发放电单位中，对３种刺激均产生兴奋（Ｅ）、抑制（Ｉ）及无反应（ＮＲ）３种形式的反应，表明大鼠Ｌ２节段脊髓存在躯体、内脏和躯体内脏反应性神经元，并有会聚和阻塞现象。在脊髓缺血再灌流时，神经元对ＰＮＶ、ＶＬＮＶ、ＳＶ也产生Ｅ、Ｉ、ＮＲ３种形式的反应，提示脊髓缺血再灌流时神经元对躯体和内脏传入刺激的反应形式不受影响；但缺血时ＳＣＵＤｓ对ＰＮＶ、ＶＬＮＶ产生反应的单位数减少，这表明脊髓缺血损伤时神经元对躯体和内脏传入刺激的反应性减弱，随着缺血损伤加重，脊髓神经元对躯体内脏信号的整合功能下降

外周血及移植肾内嗜酸性粒细胞变化的临床意义

为了解移植肾在急性排斥时外周血和移植肾内嗜酸性粒细胞（ＥＯ）变化的意义，动态观察３１例同种异体肾脏移植病人的外周血和移植肾内ＥＯ的变化。结果发现在急性排斥反应时，移植肾内ＥＯ数＞２％者占８０．９％，明显高于肾功能稳定时，Ｐ＜０．０１；重度排斥中血ＥＯ数＞４％者占８２．６％，明显高于肾功能稳定时和中度以下排斥者，Ｐ＜０．０１。结果认为，测定移植肾内的ＥＯ变化可以做为监测急性排斥反应的可靠指标，外周血中的ＥＯ明显增多常提示排斥反应较为严重。
