RESUMEN
Objective To explore the gender differences in disgust processing in patients with ob-sessive-compulsive disorder ( OCD). Methods A total of 74 patients with obsessive-compulsive disorder (39 males and 35 females) and 65 normal healthy controls (35 males and 30 females) were assessed with Padua inventory-Washington State University revision (PI-WSUR),Yale-Brown obsessive-compulsive scale (Y-BOCS) and were tested the lexical decision task,in order to evaluate their OCD symptoms and severity. The results of reaction time,accuracy and rating intensity of core disgust words,moral disgust words and neu-tral words were recorded,and the gender differences in disgust processing in patients with obsessive-compul-sive disorder and normal healthy controls were analyzed. Results The reaction time of core disgust words ((753.6±84.1) vs (711.8±83.8)ms),the reaction time of moral disgust words((813.5±89.0) vs (749.4± 81.4)ms) and neutral words((775.3±91.8) vs (725.9±104.2)ms) showed significant differences between males and females in pateints with OCD,but there were no differences in accuracy and rating intensity(P＜0.05 or P＜0.01). In normal healthy controls,there were only differences between males and females in reac-tion time of neutral words,females were also showed shorter reaction time than males (P＜0.01). Pearson cor-relation analysis showed that both male and female patients had a negative correlation between the reaction time of core disgust words and total PI-WSUR scores (P＜0.05). There was a gender difference in the relative variables of PI-WSUR,Y-BOCS and disgust processing in OCD patients. Conclusion There were gender differences in disgust cognitive processing in patients with obsessive-compulsive disorder,females with ob-sessive-compulsive disorder have higher core disgust and moral disgust than males. Females with OCD have a special high sense of moral disgust.
RESUMEN
Objective This study aims to investigate the moral disgust cognitive processing of patients with obses?sive-compulsive disorder (OCD) and its relationship with OCD symptoms. Methods Twenty-eight OCD and 30 healthy controls matched for gender, age and education completed lexical decision task, recording reaction time and accuracy of words and assessing the degree of disgust. Yale-Brown obsessive-compulsive scale (Y-BOCS) and Padua Invento?ry-Washington State University Revision (PI-WUSR) were used to assess the symptoms. Results OCD group showed significantly longer reaction time to core disgust-related words [(762.69 ± 128.25) ms vs. (648.69 ± 162.66) ms] and moral disgust-related words [(798.73 ± 115.26) ms vs. (727.00 ± 106.06) ms] than the healthy controls (P<0.05). OCD group showed significantly higher aversion degree to core disgust-related words [(6.38 ± 1.78) vs. (5.03 ± 1.64)] and moral dis?gust-related words [(7.08 ± 1.23) vs. (5.77 ± 1.44)] than control group (P<0.05). Y-BOCS total score, Y-BOCS obsessive thoughts score, Y-BOCS compulsive behavior score, total score of PI-WUSR, cleaning/pollution force factor score, hurt?ing themselves and others force factor were positively correlated with two types of disgust-related words in patients group (P<0.05). Multiple stepwise regression analysis between disgust words and Y-BOCS/PI-WUSR scores pointed that only CWCF influenced disgust degree of core disgust-related words (β=0.61, P<0.01) and moral disgust-related words (β=0.54, P<0.01), respectively. Conclusion The core disgust and moral disgust of OCD are stronger compared to controls.
RESUMEN
<p><b>OBJECTIVE</b>Using the carbon tetrachloride liver cirrhosis rat model, the protective effect of the green tea extractive (GTE) on the liver cirrhosis was studied.</p><p><b>METHODS</b>Male SD rats were randomly divided into three groups: normal group, GTE group and cirrhosis group. The GTE group and the cirrhosis group were injected subcutanuously 2 times/wk over 9 weeks with 40% CCl(4). In the second and the ninth week, the rats were sacrificed to measure MDA and hydroxyproline concentrations and TGF-beta(1) mRNA expression in liver tissue, as well as to conduct histological examination on various organs.</p><p><b>RESULTS</b>Compared with the cirrhosis group, the MDA and the hydroxyproline concentrations in the GTE group were significantly reduced (P < 0.05). The liver necrosis and cirrhosis were extenuated in the GTE group by means of histologic examination. The expression of the TGF-beta(1) mRNA was reduced significantly in the GTE group.</p><p><b>CONCLUSION</b>Dietary supplementation of GTE can protect against CCl(4)-induced liver damage and cirrhosis in rats.</p>
