BACKGROUND: The purpose of this study was to analyze the relationships between cardiorespiratory fitness and body mass index (BMI), metabolic syndrome risk factors, homeostasis model assessment-insulin resistance (HOMA-IR), and high sensitivity C-reactive protein (hsCRP) in male high school students in Korea. Furthermore, the effects of the cardiorespiratory fitness levels on these four factors were examined. METHODS: The level of cardiorespiratory fitness, BMI, percent body fat, waist circumference (WC), systolic blood pressure, glucose, triglycerides (TG), high-density lipoprotein-cholesterol (HDL-C), HOMA-IR, and hsCRP of 227 male high school students were measured. Analyses of multiple correlation and simple regression were applied. RESULTS: The results showed that the level of cardiorespiratory fitness correlated negatively with BMI, percent body fat, WC, TG, and HDL-C, in addition to HOMA-IR and hsCRP, and strongly influenced BMI, percent body fat, WC, TG, HDL-C, HOMA-IR, and hsCRP. Comparative analysis of our subjects showed that higher cardiorespiratory fitness levels had positive effects on BMI, metabolic syndrome risk factors, HOMA-IR, and hsCRP. CONCLUSIONS: This study found that there are close correlations between cardiorespiratory fitness and BMI, metabolic syndrome risk factors, HOMA-IR, and hsCRP. It also showed that, compared to lower levels of cardiorespiratory fitness, higher levels had beneficial effects on BMI, metabolic syndrome risk factors, diabetes, and cardiovascular disease risk factors.

OBJECTIVE: To compare the age of menarche, changing patterns of the menstrual characteristics in adolescent girls between 1988 and 1998. METHODS: A survey was undertaken for 1,500 highschool girls and compare with those of pervious study for 5,000 middle and highschool girls performed by same author in 1998 by means of questionnaire. RESULTS: During a decade, the mean menarcheal age decreased from 13.5+/-1.0 to 12.7+/-1.0 years(p=0.001). Gynecologic age, Body mass index were associated with age of menarche in both 1988 and 1998. The interval of menstruation was 30.6 3.5dyas in 1998 and shortened compared with 32.1+/-6.3 days in 1988(p=0.001). The duration of menstruation was lengthened in 1998 than in 1988(6.1+/-1.1 days vs 5.8+/-2.2 days, p=0.001). The incidence of irregular cycle(28.2% vs 58.2%, p=0.001), dysmenorrhea(73.9% vs 77.8%, p=0.001), and secondary amenorrhea(16.2% vs 27.2%, p= 0.001) decreased in 1998 compared with those of 1988. The incidence of agonies about menstruation was also decreased in 1998 than in 1988(26.2% vs 69.1%, p=0.001). The most common agony about menstruation in 1988 was irregular cycle(28.4%), but dysmenorrhea( 64.3%) in 1998. CONCLUSIONS: From the above results, the mean age of menarche was advanced since last decade but most of the adolescent girls still have suffered from dysmenorrhea.

461 cases of renal biopsy specimens were summerized correlated with their light microscopic and immunofluorescence findings, which obtained from Jan. 1981 to Jul. 1986 at Department of Pathology, Kyung Hee School of Medicine, The results were as follws: 1) The incidence of IgM nephropathy was about 5.8% of the primary glomerulopathy. 2) Sex distribution showed male preponderance with male: female ratio of 1.7:1. 3) Age distribution were 0-9 years 7.4%, 10-19 years 29.6%, 20-29 years 37.0%, 30-39 years 7.4%, 40-49 years 7.4% and 50-59 years 11.1%. 4) The clinical symptoms were gross hematuria 7.4%, microscopic hematuria 59.2%, proteinuria (nonnephrotic) 37.0%, nephrotic syndrome 55.5%, hypertension 7.8% and edema 59.2%. 5) 9 cases (33.3%) had past histories of upper respiratory infections. 6) The distributions of the light microscopic deagnosis were minimal histologic change 11 cases (40.7%), focal glomerulonephritis 7 cases (25.9%), measangial proliferative glomerulonephritis 5 cases (18.5%), focal and segmental glomerulosclerosis 1 case (3.7%) and poststreptococla glomerulonephritis 1 case (3.7%). 7) Immunofluorescence study showed significant diffuse mesangial granular deposits of IgM and C3 in all of the 27 cases. 8) It was demonstrated that in the patients with nephrotic syndrome, the prognosis for the patients with IgM deposition were less favorable than those without IgM deposition.

We report two human cases of tick bite. A 63-year-old male had a pruritic pea-sized brownish nodule on the left popliteal area. Another 41-year-old male had an asymptomatic bean-sized black nodule in the pubic area. The ticks were identified as Ixodes nipponensis, which are the 18th and the 19th cases in Korea.

In this study, I made researches of 510 mothers who breed their infants in total (256 boys & 254 girls), among which 410 in urban area and 100 in the rural area, as an object of the investigation so as to make an intensive examination and analysis of the actual state of feeding nutritive method, grasp several related factors, and finally suggest the elementary data for both campaign encouraging breast feeding and the infant feeding education. 1. Mothers showed the meaningful local differences as in an education and income level at 1% and as in a delivery type at 5%. 2. To have decided the feeding conditions according to the residences by the Kaup index distribution (P<0.05) resulted in a meaningful difference according to regions and also made us be more thoughtful of the overnutrition in the urban area than in the rural area, and it didn't showed a meaningful difference the nutritive state according to the infant feeding method thought desirable (P<0.01). 3. The feeding methods consist of breast feeding at 21.8%, artificial feeding at 48.8%, and the mixed one at 29.4%. As for the feeding method thought desirable, breast feeding was 52%. Even though they were thinking that breast feeding is better, the breast feeding case didn't go beyond 32.5% only and as for the actual feeding methods it showed a meaningful difference according to the feeding method thought desirable (P<0.01). 4. Regarding the reasons why they chose breast milk, it was 64%, the most because mother's milk contains the immune system, 63.1% for the baby's health, 52.3% because of its most because breast milk is of little quantity, 37.8% because of the mother's occupation, 14.1% because they have fed the baby artificially from the beginning and so on. Considering the reasons why they chose the mixed feeding, it was 70.7%, the most because the amount of breast milk a little, 27.3%, the next one, because of the mother's occupation and so on. 5. The respondents who answered that how to increase the number of breast feeding population depends on the reinforcement of breast feeding education for the women were 190 (37.3%), the most among all 150 persons and those who had the opinion that they should spread and actualize the temporary childcare rest (from office) system for the women who have jobs were the secondly most, 107 (21%).

We report a case of malignant tumor of the stomach showing both carcinoma and sarcoma components in a 47 year-old woman. The resected stomach revealed two tumors which were in different location. The one mass was a 2 x I cm, poorly demarcated tumor at the body, along the lesser curvature and the other was a 6 x 7 cm, well demarcated polypoid tumor with a central depression at cardia of the posterior stomach wall. The tumor at the body was a poorly differentiated adenocarcinoma which showed strong reactivity for CEA. The tumor at the cardia was composed of epithelioid or spindle shaped cells with abundant eosinophilic cytoplasm and revealed 5-6 mitoses per ten high power field. The tumor at the cardia was diagnosed as epithelioid leiomyosarcoma and showed reactivity for vimentin but none for actin, desmin,keratin, and CEA. This is different from the usual carcinosarcoma.
