Journal of Pharmaceutical Analysis 2007年第2期19卷 191-194页

作者：于燕胡森科孙晓英张敬华刘伟周玲颜虹 Department of Public Health Medical School of Xi'an Jiaotong University

Objective To observe the toxic effect of the mixture of organophosphorus pesticide (MOP) on maternal rats and on the growth and development of their offspring. Methods Totally 40 Sprague-Dawley pregnant rats were randomly divided into three MOP dose groups and one control to which their offspring would be assigned. The experimental dosage of MOP and distilled water were administered orally starting on gestation day 15 and continued for 35 days. The physical development indices and the learning ability of F1 rats were measured during lactation. The pathological changes of uterus and liver of F0 rats were observed after weaning, while the weight ratio of uterus and some viscera to body of the F1 were examined. Results There were obvious changes of uterus and liver in the high-dose group of F0. The body-weight accretion of the F1 in high-dose group was obviously lower than that in control group (Pperinatal rats.

Effects of Supplementation with <i>Saccharomyces cerevisiae</i>and Its Fermentation Products on Production Performance and Its Mechanism in perinatal Dairy Cows

引用

Advances in Bioscience and Biotechnology 2021年第7期12卷 193-212页

作者： Xueyan Lin Ke Li Lin Ju Xu Hao Yue Jiang Qiuling Hou Zhiyong Hu Yun Wang Zhonghua Wang College of Animal Science Shandong Agricultural University Tai’an China

The aim of this study was to investigate the effects of Saccharomyces cerevisiae and its fermentation products on performance, blood hormone levels and rumen floral composition in peripartum dairy cows. Sixty perinatal cows were selected and allocated to two groups according to parity and expected date of delivery. Each group was supplemented with Saccharomyces cerevisiae and its fermentation product 0 or 100 g. The results showed that Saccharomyces cerevisiae and its fermentation products could significantly increase the feed intake of peripartum dairy cows (P β-hydroxybutyrate (P = 0.01), reducing the insulin content (P = 0.02). Saccharomyces cerevisiae reduced the abundance of rumen microbes in peripartum dairy cows but had no effect on rumen microbial diversity. Compared with the control group, the supplemented group showed reductions in the abundance of genera Bacillus (P = 0.03), Butyrivibrio (P = 0.01),

围产期抑郁将危害孕产妇的个体、家庭及社会。针对孕产妇及其家庭成员的围产期预防抑郁项目，以贝克抑郁自测量表、家庭关怀度量表及孕产妇自我效能感量表为测量工具，通过改变孕产妇自我效能感与家庭支持两个中介变量达到预防和缓解围产期抑郁的干预目标。干预手册方案的设计过程应遵循满足个性需求、了解干预对象、平衡中介变量和兼顾整体环境的处置原则。随着循证研究的兴起，社会工作与心理学将在心理健康领域呈现融合趋势。社会工作在吸纳心理学理论与方法的基础上，将以整体性视角看待个体问题，并致力于发挥他者自身的潜能。其对社会公平的价值取向、对人类福祉的追求都将更符合社会整体的发展与进步。研究者也应在尊重循证研究环节的科学性和有序性的同时，兼顾人文关怀，时刻保持批判性自省，从而推动社会工作领域中干预研究的进一步应用与发展。
