Health (Health) , 2009, DOI: 10.4236/health.2009.12014
Abstract: Objective: To observe the concentration of se-rum homocysteine in intellectuals and the re-lated influential factors. Methods: The concen-trations serum homocysteine and saliva cortisol were measured in 138 intellectuals from three cities, Tianjin, Guangzhou and Chengdu in China. All the subjects had senior titles of tech-nical post, aged 40-69 years. Results: The mean value of serum homocysteine concentration in intellectuals was 20.6±0.8μmol/L, higher than the reference value. With the increase of cortisol levels the homocysteine concentrations rise (P <0.05). The mean value of homocysteine con-centration was highest in 40-49 years old group. Men had higher homocysteine level than women in this investigation. According to the mean value of homocysteine concentration among different cities, Tianjin was highest, Chengdu medium, Guangzhou lowest. Conclusion: The serum homocysteine concentration of intellec-tuals is higher than the reference value. The stress level, gender and resident cities might contribute to the differences in serum homo-cysteine concentration in Chinese intellectuals.

Abstract: 氯甲基苯乙烯-二乙烯苯共聚体(简称氯甲基共聚珠体)的合成,当采用传统的氯甲醚法时,由于混杂有容易致癌的二氯甲醚而不甚妥善.不直接使用氯甲醚的氯甲基化方法,虽已有些专利报道,但并不具体.本文研究氯化硫酰-甲缩醛法制备氯甲基共聚珠体,可在氯化硫酰、甲缩醛、催化剂无水氯化锌用量甚低的情况下,得到氯甲基共聚珠体含氯量稳定在16—17.7%,合成的强碱型阴离子交换树脂的交换当量稳定在3.3—3.5毫克当量/克(干树脂),而且发现甲缩醛中少量甲醇或水的存在对氯甲基化反应影响甚微.
