PURPOSE: Is there any relationship between penile size and physical stature? This study was performed to answer this question and provide guidelines of penile size to assist in counseling patients for penile augmentation. MATERIALS AND METHOD: Penile size, body weight and height were measured in 150 young healthy men, and the body mass index(BMI) was calculated in weight(kg)/height(m)2. The penile length and circumference were measured with tape in flaccid and erect states. The 'lengthening ratio' was calculated by 'erect length/flaccid length', and 'tumescent ratio' was calculated by 'erect circumference/flaccid circumference'. All the data was statistically evaluated and the following results were obtained. Result : The average length and circumference were 8.26+/-1.07cm and 8.34+/-1.03cm respectively in the flaccid state, and 13.42+/-1.38cm and 11.17+/-1.05cm in the erect state. The average lengthening and tumescent ratios were 1.64+/-0.22 and 1.35+/-0.08, and were negatively correlated to the flaccid penile length and circumference. Height was positively correlated to erect penile length and lengthening ratio. There was a relationship between body weight and erect penile length in a positive direction, but with other penile parameters there were none. There was no relationship between BMI and any parameters of penile size. However, the erect penile length of the normal BMI group was longer than that of the lower BMI group. CONCLUSIONS: The results show that the flaccid penile size is related to the erect penile size and there is some relation between penile size and physical stature. We believe these results will be applicable to the penile augmentation.

This tutorial describes sources of pharmacokinetic variability that are not obviously linked to genetic differences. The sources of variability are therefore described as environmental. The major quantitative sources of environmental variability are body size (including body composition), maturation and organ function. Size should be considered in all patients. Maturation is mainly relevant to neonates and infants less than 2 years of age. Renal function is the most important predictable source of variability due to differences in organ function.

This study was conducted to find adolescent females perception of body image. The survey was carried out by self-questionnaires with 463 female school and college students in Daegu. Analysis of data was done using t-test, and ANOVA with the SAS computer program. The average height, weight and BMI of the subjects were 161.2cm, 53.4kg and 20.51kg/m2. It appeared that 33.3% of the subjects were off the normal range of body weight ; in particular 25.1% of the subjects were under weight. While the subjects' perception of their own current body image was not distorted, they were dissatisfied with their body image because they wanted a very thin figure. Subjects were divided into 3 groups -underweight, normal weight, overweight-according to their current body size. Their perceptions of ideal and desired figures differed significantly between the groups, but they thought a thinner figure than normal body image as ideal and desired body image even in overweight group. As a result, dissatisfaction of body image in the overweight group was significantly larger than the normal-weight group, and that of the normal-weight group was larger than the underweight group. Percentages of weight control attempt were 51.7% and 64.7% in the normal weight and underweight subjects, respectively. Subjects were divided into 2 groups according to their weight control experience : those who have attempted, and who have not attempted. Weight control attemptees had a higher level of dissatisfaction with their body image than non-attemptees, both because weight control attemptees were fatter, and they perceived a thinner figure as an ideal and as a desired body image thin non-attemptees. From the results of this study, we confirmed that one of reasons of excessive weight control behavior among adolescent females was distorted perception about ideal body image.

PURPOSE: This study was conducted to assess the usefulness of fat-free mass index (FFMI) and fat mass index (FMI) as novel expression methods of body composition in children. METHODS: A total of 466 Second grade students-248 boys and 218 girls- from all elementary schools the Gwacheon City underwent anthropometric measures including bioelectrical impedance analysis (BIA) and biochemical tests. The correlation coefficients between obesity indices, including FMI and FFMI, and metabolic risk factors, were assessed. Metabolic risk factors of children with increased FMI were compared with those of children with normal FMI. We compared FMI and FFMI percentile distribution between this study's subjects and the subjects of the Fukuoka body composition study. RESULTS: FMI was lower and FFMI was higher in this study's subjects compared to the subjects of the Fukuoka body composition study. FMI was correlated with other obesity indices and several metabolic risk factors. Metabolic risk was higher in children with increased FMI than in children with normal FMI. CONCLUSION: FMI and FFMI were useful indicators in comparing difference of body composition among children that had different body size and growth. High FMI was related to increase of metabolic risk in children.

The Mapleson type D is one of the non-rebreathing systems used in pediatric general anes- thesia. Because it doesnt have soda lime, the fresh gas tlow (FGF) must be adjusted to the patient's size, body temperature and the anesthetic technique to prevent CO2 retention. We have used the FGF of 2-3.5 L/min according to patient's body weight, whether or not the patient has a fever. So, we examined arterial blood gas analysis in 3 pediatric patients with fever. We suggest that if a patient has a fever, it is desirable to inmease FGF to 5 L/min to prevent CO2 accumulation or acidosis.

The study purpose was to examine weight control status and related factors among 370 high school girls in Seoul. Factors examined included interest toward weight control, body satisfaction, body image, beliefs regarding weight control and self-efficacy. 65.1% had attempted to control weight and were categorized into attempt group. Those in the attempt group had higher body weight (p<0.001) and BMI (p<0.001) than the counterparts. They tried to control weight 2.9 times on average (22.4 days each time). The major information sources for weight control were internet (62.8%), and TV/ radio (17.1%). Exercise was most commonly used for weight control, followed by reducing meal amount and skipping dinner. The attempt group was less satisfied with body size (p<0.001) and perceived their body sizs as heavier than the counterparts (p<0.001), but they showed more interest toward weight control (p<0.001). The ideal body size of society or the body size that they want was very thin in both groups. Twelve out of 20 beliefs regarding weight control were significantly different between the two groups. The attempt group believed more strongly on the advantages such as increased self-confidence, appearance, attractiveness (p<0.001) and 'good for making friends' (p<0.01). In contrast, the attempt group believed less strongly about the disadvantages including harmful effects on health (p<0.001), parents' dislike, feelings of discouragement (p<0.01) and becoming (p<0.05). The attempt group showed lower overall self-efficacy to control overeating (p<0.05) than the counterparts. Especially, the attempt group felt less control of overeating in situations such as eating-out, after school, when they are with family (p<0.01) or with friends, when they feel hungry, during examination periods and when others offer food (p<0.05). This study suggested that weight management education for adolescents include strategies for changing body image and beliefs regarding weight control, as well as increasing self-efficacy to control overeating.

PURPOSE: To provide the epidemiological information for developing preventive programs encourage appropriate eating and weight control behaviors. METHOD: 349 college students in Seoul were administered self-report question- naires to examine eating habits, trend of disordered eating, weight reduction practice and body size evaluation from September to October 2002. Data were analyzed by SAS program for frequency, t-test, ANOVA with Scheff test. RESULT: The mean eating score was moderate and it differed by subjects' characteristics. The mean score of EAT-26 was relatively lowered, and 3.4% of the subjects score showed disordered eating behavior. It differed significantly by subjects' general characteristics. 30.4% of total sample were currently trying to lose weight and had interested in trying to lose weight. EAT-26 was significantly different by weight reduction practices and interest. Perceived body size differed by the score of eating habit and EAT-26. CONCLUSION: It can be suggested weight preoccupation have a relation to eating habits, weight control practice and disordered eating. Further study is recommended educational interventions targeting at-risk subjects.

Objective: The present study was undertaken to evaluate the subchronic oral toxicity of sodium dehydroacetate (DHA-Na) and to determine the point of departure (POD), which is a critical factor in the establishment of an acceptable dietary intake. Methods: DHA-Na was administered once daily by gavage to Sprague-Dawley rats at dose levels of 0.0, 31.0, 62.0, and 124.0 mg/kg BW per day for 90 days, followed by a recovery period of 4 weeks in the control and 124.0 mg/kg BW per day groups. The outcome parameters were mortality, clinical observations, body weights, food consumption, hematology and clinical biochemistry, endocrine hormone levels, and ophthalmic, urinary, and histopathologic indicators. The benchmark dose (BMD) approach was applied to estimate the POD. Results: Significant decreases were found in the 62.0 and 124.0 mg/kg BW groups in terms of the body weight and food utilization rate, whereas a significant increase was found in the thyroid stimulating hormone levels of the 124.0 mg/kg BW group. Importantly, the 95% lower confidence limit on the BMD of 51.7 mg/kg BW was modeled for a reduction in body weight. Conclusion The repeated-dose study indicated the slight systemic toxicity of DHA-Na at certain levels (62.0 and 124.0 mg/kg BW) after a 90-day oral exposure.

PURPOSE: Kidney size (KS) is used to diagnose the patients with renal disease. When the length of a kidney is measured under 9 cm, it is considered to indicate an irreversible disease. Because glomerular filtration rate (GFR) decreases with age, the normal range of KS in the elderly is indefinite. Therefore, we measured KS in adults older than 80 years old and investigated correlated factors. METHODS: One hundreds six adults (51 men, 55 women: mean age 83+/-0.3) without renal disease were included. Their serum creatinine (Scr) levels did not exceed 1.3 mg/dL, and the calculated GFR were over 60 mL/min/1.73m2. Abdominal ultrasonography were performed to all of them and their body indexes (BI) were measured. RESULTS: 1) The mean length of kidney was 9.9+/-0.07 cm. 2) KS in the early eighties was larger than that of adults over ninety. 3) KS showed negative correlations with age and Scr, but a positive correlation with body surface area . 4) The calculated GFR showed correlations with the surface areas of both kidney (BK) by C-G equation and with the size of BK by MDRD equation. 4) The GFR calculated by MDRD and C-G equation presented inverse correlations with Scr, but only MDRD equation showed a statistic significance. CONCLUSION:In the elderly, KS may be smaller than that of younger adults. Other factors such as either surface area or volume of BK and BI should be considered to estimate the individual KS to decide whether the size is within normal range.

BACKGROUND: Increased left ventricular mass in patients with essential hypertension, coronary artery disease, chronic renal failure or in general population has been suggested as a useful predictor of increased cardiovascular morbidity and mortality. Many studies have reported that left ventricular mass is correlated postively with body size. Thereafter normalization of left ventricular studies, but it is uncertain which is appropriate. This study was designed to determine the appropriate method for normalization of left ventricular mass to exclude influence of body size in normal adults. METHODS: We measured left ventricular mass 100 normal adults by M-mode echocardiogram using ASE cube method without(Devereux and Reichek's method) and with correction(Devereux and Alonso's method). Left ventricular mass were normalized for body weight, height, body surface area, body surface area1.5, height2.0 and height2.7 RESULTS: 1) Left ventricular mass by Devereux and Reichek's method correlated well with that by Devereux and Alonso's method(r=1.0,p<0.001). 2) Corrected left ventricular mass correlated well with weight(r=0.64, p<0.001), height(r=0.49, p<0.05), body surface area(r=0.53, p<0.01) and body mass index(r=0.58, p<0.001). 3) Correlation coefficients of left ventricular mass/weight with weight, of ventricular mass/height with height, of ventricular mass/height2.0 with height, of ventricular mass/height2.7 with height, of ventricular mass/body surface area with body surface area and of ventricular mass/body surface area1.5 with body surface area were 0.12, -0.05, -0.29, -0.42, 0.13 and -0.11 respectively. 4) Peak systolic wall stress correlated with age and left ventricular mass, but end systolic wall stress did not correlated with left ventricular mass. CONCLUSIONS: The current indexation method of left ventricular mass for height may reduce the variability associated with body size. Furthermore, it could be used reliably in normal Korean adults.
