An Assessment of Gender Differences in the Perception of Benefit Resulting from the Loss of a Child

The current study focused on a sample of adults (N = 67) experiencing bereavement following the loss of a child. The Post Traumatic Growth Inventory (PTGI) was used to assess whether bereaved parents were able to perceive benefit from their trauma, and whether there were gender differences in perception of benefit. The impact of the following variables on the PTGI was also assessed: the nature and length of time since the loss, and the age and marital status of the bereaved. The results indicated that bereaved parents do perceive benefit from their loss. However, there was poor evidence to suggest perception of benefit along gender lines. Results also indicated a potential relation between greater perception of benefit and those bereaved through illness, and more perception of benefit for the longer the time elapsed since the bereavement. Lastly, there was a tendency for younger individuals and married respondents to obtain higher scores on the PTGI.     

IMPACT OF AGRO CLIMATIC AND SOCIO-ECONOMIC VARIABILITY ON THE NUTRITIONAL STATUS OF INHABITANTS In THE GARHWAL HIMALAYAS

The Garhwal Himalayas are a part of a unique ecosystem, with sharp agro-climatic variations within a very small geographical area (53,485 km²). The varied agro-climatic situations result in different cropping systems and socio-economic lifestyles that could likely affect the nutritional status of the people living in this region. This article will attempt to explore the impact of these variables (namely, age, family size, education, income, calorie and protein intake, land holding, number of animals, and wheat production) on the body mass index (BMI) of the population residing in the Garhwal Hills. A total of 1,030 subjects were studied from the three agro-climatic zones (406 from the high hills, 292 from the mid hills, and 332 from the low hills). It has been found that the people living in the high hills are the most undernourished, as the lowest percentage of people (52.6 per cent) with an acceptable BMI and the highest percentage of people in the severely malnourished category (11.1 per cent) are found here. People living in urban areas have a better nutritional status. Correlation studies show that the nutritional status of the population improves with age, literacy levels, and small family size. In some cases, calorie and protein intake have a positive impact on the health of the people, whereas size of land holding, number of animals, and income of the family do not have any significant influence on nutritional status.

不同性别大鼠创伤失血性休克后多形核白细胞反应的差异及胃复安干预的实验研究

本研究在以下几个方面具有创新：（1）将腺苷引入心肺复苏治疗中，观察腺苷与肾上腺素合用对心跳停搏后A主循环恢复率和复苏成功率的影响，结果表明合用腺苷可明显提高自主循环恢复率和复苏成功率；（2）观察腺苷在心肺复苏中对兔心、脑组织病理结构和超微结构的影响，结果表明腺苷可以明显减轻心脑组织的损害；（3）观察腺苷窒息大鼠心脏和肠系膜微循环的影响，并观察到肾上腺素对微循环无明显改善作用，联合应用腺苷可以改善微循环；（4）将激光多普勒血流量图象仪引入心肺复苏中，动态观察窒息大鼠肠壁组织血液灌流量变化，并观察到腺苷可以增加肠壁组织血流灌注量。[编者按]     

Age at onset of schizophrenia: gender differences and influence of temporal socioeconomic change

This study was undertaken to examine whether males develop schizophrenia at a younger age than females, and whether temporal socioeconomic change affects the age at onset of schizophrenia. The subjects were 848 ICD-9 schizophrenics who were admitted to Nihon University Hospital, Tokyo, Japan, during the period of 1955-64 (n = 468 (214 males and 254 females), group A) or during the period of 1982-91 (n = 380 (220 males and 160 females). group B). Schizophrenic males showed an earlier age at onset than schizophrenic females. However, the mean age at onset of schizophrenia did not differ significantly between group A and group B. These results indicate that the gender difference in age at onset of schizophrenia has not been influenced by temporal socioeconomic change.     

Uptake and disposition of inhaled methanol vapor in humans.

Methanol is a widely used solvent and a potential fuel for motor vehicles. Human kinetic data of methanol are sparse. As a basis for biological exposure monitoring and risk assessment, we studied the inhalation toxicokinetics of methanol vapor in four female and four male human volunteers during light physical exercise (50 W) in an exposure chamber. The relative uptake of methanol was about 50% (range 47-53%). Methanol in blood increased from a background level of about 20 to 116 and 244 microM after 2 h exposure at 0, 100 ppm (131 mg/m3) and 200 ppm (262 mg/m3), respectively. Saliva showed substantially higher levels than blood immediately after exposure. This difference disappeared in a few minutes; thereafter the concentrations and time courses in blood, urine, and saliva were similar, with half times of 1.4, 1.7, and 1.3 h, respectively. The postexposure decrease of methanol in exhaled air was faster, with a half time of 0.8 h. The methanol concentrations were approximately twice as high in all four types of biological samples at 200 compared to 100 ppm. No increase in urinary formic acid was seen in exposed subjects. Our study indicates non-saturated, dose-proportional kinetics of methanol up to 200 ppm for 2 h. No gender differences were detected. Similar, parallel patterns were seen with regard to the methanol time courses in blood, urine, and saliva, whereas the concentration in exhaled air decreased markedly faster. Thus, apart from blood and urine, saliva also seems suitable for biomonitoring of methanol exposure.
