This study was performed to investigate the risk factors for coronary heart disease in elderly women. Seventy five elderly women over 65 years of age participated with 35 elderly men over 65 years of age, 40 middle-aged men and 31 middle-aged women as control subjects. The percentage of body fat(34.1 5.6%) in elderly women found to be significantly higher than in other groups and their waist/hip circumference ratio(WHR) was higher than in middle-aged women. The concentrations of plasma total cholesterol and LDL-cholesterol in elderly women were higher than in other groups, TG concentration higher than in middle aged women and HDL-cholesterol % lower than in other groups. Plasma cholesterol ester transfer protein(CETP) activities of elderly women were significantly higher than in middle-aged subjects, but were not different from those of elderly men. Plasma Apolipoprotein(Apo) A-I level in elderly women was higher than in middle-aged men but not different from the other groups. Differences among groups were not great in Lipoprotein (Lp)(a)levels. CETP activities were significantly correlated with age, body fat % total cholesterol, LDL-cholesterol and Lp(a). Therefore, it appears that the increased risk of coronary heart disease in elderly women is due to the increase of body fat, central adipose distribution, serum total cholesterol, LDL-cholesterol and CETP activities.

Purpose: This study is a descriptive study to analyze the relationship between the cognitive function, body image and pain, and the influencing factors on the daily life performance of brain injured patients. Methods: The study subjects were 119 inpatients with brain injury who gave informed consent. The activities of daily living (ADLs), cognitive function, pain and body image were measured by Modified Barthel Index (K-MBI), K-MMSE (Mini-Mental State Examination), Visual Analog Scale (VAS), Semantic Differential Method (SDM), respectively. Results: ADLs was significantly associated with body image, cognitive function, and pain. Multiple regression analysis showed that paralysis, consciousness, cognitive function, and pain were significant factors influencing ADLs. Overall, approximately 48% of total variability in the ADLs could be explained by the 4 variables ($R^2=.477$, p<.001). Conclusion: To improve ADLs of brain injury patients, a deeper understanding of paralysis, consciousness, cognitive function, and pain of patients is required and active nursing invention should be conducted.

This study was undertaken to investigate the effect of lead on organisms. Mice received 15mg or 30mg of lead acetate per kg body weight every day for 1, 2 or 3 weeks, and the livers and kidneys were removed 24h after repeated injections. The livers and kidneys were used as sources for measurement of enzyme activities and for observation of alterations in ultrastructure. It was observed that body weights of mice treated with lead acetate were decreased when compared with those before treatment. This decrease in body weight was proportional to dose. The enzyme activities of succinate and malate dehydrogenases of experimental group that was treated with lead acetate for 1 week were nearly unchanged when compared with controls, but the enzyme activities of experimental group that was treated with lead acetate for 2 or 3 weeks were lower than those of controls. Changes in the enzyme activities were dependent on, but were not proportional to dose. Histologic examination of livers and kidneys after lead treatment showed that lead compound was accumulated and damaged in nucleus and mitochondria mainly. It was also observed that intranuclear inclusion bodies were formed only in epithelial cell of kidney proximal tubule after lead treatment. The overall changes in the ultrastructure were much greater in the livers than in the kidneys. From the above results, it nay be possible to conclude that the lead results in the decrease in body weight, reduction in the succinate dehydrogenate and malate dehydrogenase activities, and damages in the ultrastructure of kidney and liver in mouse. The presence of intranuclear inclusion bodies only in the kidney implies that these bodies protect the kidney from lead toxicity to some extent.

Objective: The objective of this study was to investigate the effects of drive-assisting system in a shower carrier on the upper body muscle activities of caregivers through drivability tests. Background: In care facilities, one of the major ADL (Activities of Daily Living) factors is bathing/showering. Recently, bath/shower-assisting equipment is actively being introduced in care facilities to reduce caregivers' muscle burden. In particular, it is desirable to utilize a shower carrier equipped with drive-assisting system to effectively care for the elderly. However, there were few systematic studies on the relationship between muscle activities and drive-assisting speeds. Method: For the drivability tests to study the effects on the muscle activities according to the drive-assisting speeds(corresponding drive-voltages: 0.0V, 2.0V, 2.1V, 2.3V), 6 females in their 40s($43{\pm}4yrs$, $157{\pm}5cm$, and $54.5{\pm}1.5kg$) were selected. To measure muscle activities of caregivers through drivability tests, 7 muscles in the upper body(TM/Trapezius Muscle, DM/Deltoid Muscle, BBM/Biceps Brachii Muscle, TBM/Triceps Brachii Muscle, ECRLM/Extensor Carpi Radialis Longus Muscle, FCUM/Flexor Carpi Ulnaris Muscle, and ESM/Erector Spinae Muscle) were selected. Results: In the TM, muscle activities were decreased as 21% compared to 0.0V, when drive-voltage 2.0V was applied, as 57% by 2.1V, and 62% by 2.3V(p<0.05), whereas 40%, 56%, and 69% of muscles activities were decreased respectively from the DM(p<0.05). Also, from the UL(BBM+TBM+ECRLM+FCUM), muscle activities were decreased by 17% with 2.0V as against 0.0V, by 47% with 2.1V, and 52% with 2.3V, whereas decreases in muscle activities from the ESM were found by 20%, 34%, and 42% respectively by 2.0V, 2.1V, and 2.3V(p<0.05). Conclusion: The muscle activities were decreased in the order of the DM, TM, ESM, and UL. As muscle activities were remarkably reduced as drive voltage were increased, it was expected to reduce the upper body muscle burden on the caregivers when using shower carriers equipped with driving-assist system. Applications: The results from this study can be applied for the development of a shower carrier including other equipment to possibly reduce the muscle burden of the caregivers.

This study was to investigate the effect of dietary protein and fiber on the antioxidant enzyme activities of brain in acute or chronic ethanol-treated rats. Male Sprague-Dawley rats were fed on diets containing two levels of protein(7%, 20%) with two levels of fiber (5%, 10%) Rats were administered 40%(v/v) ethanol(5g/kg body weight)orally 90min before decaptiation in acute ethanol-treated groups and 25%(v/v) ethanol(5g/kg body weight) once a day for 5 weeks in chronic ethanol treated-groups. The rats were sacrificed after 5 weeks of feeding periods. Superoxide dismutase and gluthathione S-transferase activities were lower in chronic ethanol-treated groups than acute ethanol-treated groups whereas catalase and glutathuone peroxidase activities were significantly increased by chronic ethanol treatment. Low protein supplement accelerated to change of their activities however dietary fiber levels did not affect antioxidant enzyme activities. Chronic ethanol treatment and/or low protein supplement results in increasing the brain lipid peroxide content but in lowering glutathione level. (Korean J Nutrition 33(6) ; 613~618, 2000)

The purpose of this study was to compare the energy expenditure of normal-weight and overweight Korean middle-aged women (40-60 yr). Middle-aged oveweight ($BMI\;{\geq}\;25$, n= 20) and normal-weight women were ($BMI\;{\leq}\;23$, n = 20) were recruited in Seoul. Anthropometric measurements, body composition, energy intake, daily activity time, and energy costs of some daily activities were measured. Energy expenditure at rest and while reading the newspaper, washing dishes, mopping the floor, and walking on a treadmill at 1.0, 2.0, 3.5mph were measured by indirect calorimeter and total daily energy expenditure was estimated by summation of energy costs of different activities. The overweight group had significantly higher values of body weight, triceps skinfold thickness, thigh circumference, waist circumference, hip circumference, BMI, WTR, WHR, body surface area, percentage body fat, fat mass, fat free mass (FFM), and muscle mass compared to normal-weight group. The energy intakes of both groups were close to RDA and other nutrient intake status was also satisfactory. There were no significant differences in intakes of energy and nutrients between the two groups. Overweight subjects showed lower energy expenditure per kg body weight for reading the newspaper, washing dishes and mopping the floor, and walking on a treadmill at 2.0 and 3.5 mph, however, energy expenditure per kg FFM did not differ between the two groups. Daily energy expenditure for all activities was significantly higher in the overweight compared to the normal-weight group due to higher body weight. Both overweight and normal-weight groups showed negative energy balance between energy intake and energy expenditure, and there was no significant difference in energy balance between the two roups. Total daily energy expenditure correlated highly with FFM and body surface area. The result of present study does not offer an explanation on the energy imbalance and weight gain of overweight women.
