The cytochrome P450 (CYP) 3A subfamily is estimated to participate in the biotransformation of 50% of the currently prescribed drugs. Four members of the CYP3A subfamily have been identified in humans: CYP3A4, CYP3A5, CYP3A7, and CYP3A43. Initial data suggested that CYP3A5 accounts for only a small proportion of the total hepatic CYP3A in about 20% of samples, but it was later revealed that CYP3A5 represents more than 50% of the total CYP3A amount in some individuals. Several genetic variants have been described for the CYP3A5 gene, of which the CYP3A5*3 allele (gA6986G), the most common form and leading to the loss of CYP3A5 activity, has been extensively investigated in the aspect of pharmacokinetics and disease risk. This review summarized the molecular characteristics of the CYP3A5 gene, and discusses the association of the CYP3A5*3 polymorphism with disease risks such as cancer and hypertension, along with its role in the pharmacokinetics of CYP3A substrates.

This review provides an overview of the current state of pediatric brain tumor imaging, emphasizing the role of various imaging sequences and highlighting the advantages of standardizing protocols for pediatric brain tumor imaging in diagnosis and treatment response evaluation. Basic anatomical sequences such as pre- and post-contrast 3D T1-weighted, T2-weighted, fluid-attenuated inversion recovery, T2*-weighted, and diffusion-weighted imaging (DWI), are fundamental for assessing tumor location, extent, and characteristics. Advanced techniques like DWI, diffusion tensor imaging, perfusion imaging, magnetic resonance spectroscopy, and functional MRI offer insights into cellularity, vascularity, metabolism, and function. To enhance consistency and quality, standardized protocols for pediatric brain tumor imaging have been recommended by expert groups. Special considerations for pediatric patients, including the minimization of anesthesia exposure and gadolinium contrast agent usage, are essential to ensure patient safety and comfort. Staying up-to-date with diagnostic imaging techniques can contribute to improved communication, outcomes, and patient care in the field of pediatric neurooncology.

BACKGROUND: Many women have experienced artificial abortion, but artificial abortion itself may take a life away from a fetus and also influence serious effect on operated womens health condition. So this study was attempted to offer basic information for improving maternity health condition by knowing womens artificial abortion performance status and recognition about its complication. METHODS: The 215 married women who visited in OPD of certain hospital in Pusan from november 1994 to January 1995, answered the question about experience of artifial abortion the recognition about its complication, and artificial abortioned group answered the reason of artificial abortion and the experience of complication. RESULTS: The number of women who experienced artificial abortion was 107 persons(49.8%). More educated women have experienced less artificial abortion. The causes of artificial abortion were birth control as of 40.6%, continuation of occupation or study as of 20.6%, for preserving health condition as of 14.2%, impossible marriage as of 14.2%. 115 persons out of 215 persons (53.4% ) answered they heard about, its complicatons. In relation to health, 66 persons(30.7% ) answered that the abortion had no relation with health condition or they answered they have no idea about the issue, 68 persons(31.6%) answered that the abortion had relation with but its complication would be soon recovered. Higher understanding was obtained in higher educated group(P<0.05). If unwanted pregnancy occur to them in the future, 32 persons(27.8%) in recognized group and 38 persons(38%) in unrecognized group answered they would perform artificial abortion. So understanding about complicaton of artificial abortion has little effect on their artificial abortion rate. CONCLUSIONS: Recognition of complications of married women is low, and recognition degree doesnt affect artificial abortion. So, not only education about complications of artificial abortion and contraception but also social performance of sharing womens responsibility for birth control or bringing up infants is necessary.

PURPOSE: Both antithrombin III(ATIII) and Gabexate mesilate(Foy) are effective for the treatment of disseminated intravascular coagulation(DIC). However, their mechanisms of action are slightly different, and combined effect of ATIII and Foy in premature infant with DIC has not been studied. We evaluated therapeutic efficacy of treatments with either ATIII or Foy alone or both in combination. METHODS: We studied 23 premature infants of gestational ages between 30 and 36 weeks with DIC. Group A(n=10) was treated by ATIII only, Group B(n=7) by Foy only and Group C(n=6) by both ATIII and Foy. Three groups were compared for volume of blood sampling and transfusion and hematologic data. RESULTS: Improvement of hematologic data(platelet, PT, aPTT, fibrinogen, FDP) was not significantly different among 3 groups. The mean volume of blood sampling during 5 days of treatment was 30 mL, 22.5 mL, and 30 mL, respectively. The mean volume of packed RBC transfusion was 12.8 mL, 9 mL, and 2.5 mL, respectively: and mean volume of platelet transfusion was 25.9 mL, 10 mL, and 0 mL, respectively, showing no significant statistical difference. But the mean volume of FFP transfusion was 141 mL only in group B, significantly higher compared to other groups. CONCLUSION: The combination therapy of ATIII and Foy significantly decreased the volume of FFP transfusion and may be more effective than monotherapy with ATIII or Foy alone in DIC of premature infant.

OBJECTIVES: The purpose of this study was to examine the electromyographic activities of the erector spinae muscle of the back and the rectus femoris muscle of the thigh, and to measure the angles of the spinal and knee flexions in order to determine the effect of wearing a back belt. METHODS: Fifteen healthy males participated in the study. Surface electromyography was used to measure the level of muscle activities at the two muscle groups. The Simi system, utilizing two-dimensional analysis of movement, was used to examine the range of motion of the back and low extremity. RESULTS: Firstly, the angle of the spinal flexion was significantly less in the back-belt-wearing group than in the control, and that of the knee flexion was significantly increased in the back-belt-wearing group. Secondly, there was no significant change in the electromyographic signals of the erector spinae muscle of the back and the rectus femoris muscle of the thigh. CONCLUSIONS: The use of back belts helps workers to correct their posture when lifting boxes. It can therefore protect workers from acute back injuries.

The term body composition describes the percentages of fat, bone, and muscle in the human body; it reflects the nutritional or growth status in children and adolescents. Further, its evaluation is clinically important to assess the nutritional abnormalities, growth failure, progress of chronic diseases, or treatment measures for these conditions. Body composition parameters such as total body fat and fat distribution are risk factors for metabolic disease not only in adults but also in children and adolescents. Inadequate bone mineral acquisition and failure to achieve peak bone mass is a risk for subsequent osteoporosis. Therefore, measuring the body composition is important to ascertain the natural course of metabolic diseases and to develop strategies for their prevention because the body composition of children and adolescents is predictive of their body composition as adults. This article will review the basic concept and methods of measuring body composition. This review also deals with the evaluation of body composition in Korean children and adolescents. Because the body composition of individuals differs with age, body weight, puberty, sex, race, and ethnicity, it is important for pediatricians to know the characteristics of the body composition change in Korean children and adolescents.

The purpose of this study was to investigate the dietary intake, obesity index and psychosocial factors influencing obesity among 200 high school girls in Seoul. The Social Cognitive Theory provided the Conceptual basis for this study. A cross-sectional survey was conducted to examine factors related to obesity, including self-efficacy for controlling overeating, social support for eating behavior, perception of body image and weight control, nutrition knowledge, and attitudes toward obesity. The data were analyzed using t-test and multiple logistic regression. The results of this study are as follows : 1) The mean age of the girls was 16.4 years, and the rate of overweight and obesity(measured by obesity index) was 27.0%. 2) The mean energy intake of subjects was 1832.3+/-384.0kcal. The energy derived from carbohydrates, proteins and fats was 62.7%, 13.8%, and 23.5%, respectively. There was no significant difference between the obese and the comparison group in energy intake. 3) The result of multivariate analysis indicated that obesity had a significant relation to the perception of ideal body image, social support for eating behavior, and self-efficacy for controlling overeating(p<0.01). As subjects preferred thinner body images(OR=0.39) and received less social support(OR=0.93), the odds of being classified as obese increased. The odds of being obese were also associated with self-efficacy, however, the relation was not strong(OR=1.04). 4) Specific social support was related to obesity among adolescent girls. As subjects received more support from family member, the odds of being obese decreased. The emotional support as well as family member's positive nutrition behavior plays a significant role. In addition, instrumental support from friends was associated with obesity. With repect to self-efficacy, the odds of being obese were increased as subjects felt less confident in controlling overeating when tempting food was placed in front of them or after an argument. In contrast, the obese group felt more confident in controlling overeating for the rest of the specific situations examined. These findings suggest that educational interventions for weight control should incorporate strategies to help participants realize their degree of obesity, to reduce the discrepancy between current and ideal body image, to elicit and maintain social support from friends and family, and to increase the self-efficacy for changing eating behaviors.
