This study was undertaken to evaluate the present status of A. lumbricoides infection in a rural area of Korea. The 307 residents of all age group in Gumsa Myun, Yeo Ju Gun were examined by Kato's cellophane thick smear technique. Pyrantel pamoste was administered to the Ascaris infection cases by a single dose of 5mg/kg of body weight. The whole amount of 24 hour stool during two or three consecutive days were collected sepatately. The expelled A. lumbricoides worms from the unfiltered stool remnants were collected. They were measured by the length and weight, and the sex of the worms were differentiated. The results are as follows: 1) The incidence of A. lumbricoids infection of the 307 specimens examined was 40.1%(male: 40.9%, female:39.0%). The difference according to guman sex distribution was not statistically significant. 2) Seventy two Ascaris infected cases expelled 163 worms of various size. The mean number of worms per infected case were calculated as 2.3. The sex ratio of examined female and male Ascaris was 1.5:1 3) Among the expelled 97 female worms, the genital girdle were found in 60 female worms(61.9%). Genital girdle of gemale worm was located from the head in the position of $38{\pm}4$ of total length 100. 4) The average body length of male Ascaris was $16.3{\pm}3.1cm$ and female Ascaris was $21.7{\pm}3.5cm$ 5) The relationship between the weight(Y) and the length(X) of individual Ascaris worm was plotted. Y(gm).0.32$\fallingdotseq$(cm)-3.1 in female and Y(gm)$\fallingdotseq$0.1X(cm)-0.1 in male.

This study aimed to research meal quality and the dietary behaviors of college students for desirable dietary lives and provides basic data for nutritional education by examining polymorphism distribution of the UCP2 gene according to gender, by investigating attitudes in terms of their dietary habits and dietary lives, and by analyzing serum lipid levels and body composition. A survey was conducted with a total of 222 students - 93 male and 129 females. Based on a selfreporting method, the questionnaires were answered over 20 minutes, and UCP2 insertion/deletion gene polymorphism and blood samples were also analyzed. The results showed that the male students and female students had average BMI of 22.50 and $20.73\;kg/m^2$, respectively. According to answers regarding their dietary lives, 51.4% of the students showed 'irregular eating' patterns, which is regarded as something to be corrected. In terms of eating regularity, 51.6% of the male students and 59.7% of the female students had irregular meal schedules. As the most important meal of a day, 64.0% of the students answered 'breakfast' but only 53.6% answered that they ate breakfast everyday. In addition, 39.8% of the male students and 50.4% of the female students ate between meals 'once a day'. When questioned if they were satisfied with their body shape, 17.8 and 45.2% of the male students answered they were 'satisfied' or needed to 'gain weight', respectively, whereas 17.8 and 77.5% of the female students answered they were 'satisfied' or needed to 'lose weight', respectively. The results of the UCP2 gene polymorphism analysis showed that 33.7% of the males belonged to the DI heterozygote group, 64.2% belonged to the DD homozygote group, and 2.1% belonged to the II homozygote group. For the female students, 63.4% belonged to the DI heterozygote group, 35.1% belonged to the DD homozygote group, and 1.5% belonged to the II homozygote group. According to the blood and serum lipid analyses, the male students showed average HDL-cholesterol, LDL-cholesterol, and hemoglobin levels of 57.20, 93.80, and 15.00 mg/dL, respectively, while the female students presented average levels of 56.69, 102.88, and 13.13 mg/dL, respectively. In conclusion, this study found no significant effects in terms of UCP2 gene polymorphisms, but it is suggested that practical plans must be designed that allow college students to use nutritional knowledge in their daily lives, and in particular, nutrition education needs to be develop that would enable female college students to recognize their bodies appropriately and to control their weight in desirable ways.

The migration and distribution pattern of spargana in mouse body was observed after experimental infection through mouth. The spargana were obtained from the snake, Natris tigrina lateralis, caught in Hoengseong-gun, Kangwon-do. A total of 28 male mice (ICR strain), 21∼259 in body weight, were fed each with 5 scolices (and necks) of spargana and killed after 10 minutes to 14 days. Systemic autopsy was performed on each mouse to recover the spargana. The results are as follows: 1. The spargana were found to penetrate into the stomach or duodenal wall of mice as early as 10 minutes after infection. They completed the penetration within 30 minutes and appeared in abdominal cavity. It was observed that spargana did not migrate tangentially along the gut wall but directly perforated the wall. 2. After 1 hour to 1 day the majority of spargana distributed in abdominal cavity of mice except a few which migrated to muscles or subcutaneous tissues. 3. It was within 7 days that nearly all of the spargana migrated to subcutaneous tissues. Out of total 28 in number found from subcutaneous tissues, 13 distributed around neck region, 12 around trunk and other 3 on head of mice and the most common sites were submandibular and subscapular areas. There was nearly no host tissue reaction to migrating spargana. 4. The initial length of spargana given was 4 mm in average but it increased to 12 mm after 7 days and to 35 mm after 14 days. The results suggest that spargana orally given to mice penetrate the gut wall within 30 minutes followed by escaping into abdominal cavity, and after passing through thoracic cavity or abdominal wall they anally Localize in subcutaneous tissues chieay around neck region within 7 days.

This study is to investigate effects of green tea and capsulated components mixture on body fat and serum lipid composition and fat distribution in college women students in terms of supplemented periods. During 3 months of this research, 34 college women students (average age 20.3 yr) were selected as subjects. Nutrient intake was investigated by questionnaire and 24-hr recall method. Anthropolatric assessments of the subjects were investigated by SBIA method (Segmental Bioimpedance Assay, Inbody 3.0). The results were as follows: mean body height was 162.5cm and mean body weight and mean BMI (Body Mass Index, kg/$m^2$) were 57.9kg and 21.9, respectively. Status of carbohydrate intake decreased significantly (p<0.05) and dietary fiber intake increased significantly (p<0.001) after supplementation. WHR (waist-hip ratio) decreased significantly (p<0.05) and body fat and percent body fat decreased significantly after supplementation (p<0.05). Total cholesterol and triglyceride decreased significantly after supplementation (p<0.001). Above results of this study show that green tea, silk peptide and dietary fiber supplementation-added routine diet improves body fat distribution, total cholesterol, triglyceride. Especially, declination of abdominal fat and WHR was notable, since that means diminution of risk factors for obesity and chronic degenerative diseases.

Objectives : The aim of this study was to investigate the protective effects of an aqueous extract from Taxillus chinensis (DC.) Danser (TCE) in Monosodium iodoacetate (MIA)-induced osteoarthritis (OA) rat model. Methods : Sprague Dawley male rats were divided into the following four groups (n=6 per group): Normal (saline control), MIA (MIA-induced OA with vehicle), TCE (MIA-induced with TCE treatment), and IM (MIA-induced with indomethacin treatment). Rats in which OA was induced by MIA were treated with TCE (200 mg/kg) or indomethacin (1 mg/kg) for 4 weeks. Weight-bearing on the hind legs and body weights were measured weekly. At the end of the experiment (3 weeks after MIA injection), serum aspartate aminotransferase and alanine aminotransferase levels were measured to assess the liver toxicity induced by TCE. Its effects on serum inflammatory cytokine levels and tissue histopathology were also evaluated. Results : TCE restored the hind limb weight-bearing distribution. Serum levels of Interleukin 6 (IL-6), Tumor necrosis factor alpha (TNF-${\alpha}$) and Leukotriene B4 (LTB4) were significantly higher in the MIA group than in the Normal group, but serum IL-6 levels were significantly lower in the TCE group. In the TCE group, the synovial membrane was protected in hematoxylin and eosin and Safranin-O staining, respectively. Conclusions : TCE recovered the hind paw weight bearing distribution, inhibited the production of inflammatory cytokine, and protected synovial tissue and cartilage in the OA rat model. Therefore, TCE appears to be an effective therapeutic agent for treating OA and OA-related symptoms.

Objectives : This study was aimed to assess the distribution of Sasang constitution(SC) in acute stroke patients. Methods : We assessed the type of SC of acute stroke patients in the oriental medical hospitals of 3 universities located in metropolitan region from October 2005 to October 2006 by Questionnaire for the Sasang Constitution Clssification II(QSCCII). We investigated general characteristics, stroke type, blood test results, alcohol drinking, smoking and dietary preferences according to SC. Results : 236 subjects were included into the final analysis. 1. This study showed that the proportion of So-yang was highest of all constitutions(45.3%). And the body weight, body mass index, the waist circumference(WC), the hip circumference(HC), and the WC/HC ratio recorded the significantly high result in Tae-eum. 2. In the TOAST classification, SVO was the major type occupying 81.7% in the total subjects. 3. In Tae-eum, total cholesterol, triglyceride and 2 hours postprandial plasma glucose level were the highest and fasting glucose was significantly highest of all constitutions. Conclusion : From this study, we could roughly seize the distribution of Sasang constitution in acute stroke patients. For the further research, it seems to be necessary to construct fundamental databases for stroke by increasing the number of patients and by analyzing delicate characteristics of each constitution type.

The present investigation was focussed mainly on the development of the tumors and proliferating cells on the intestinal tracts of 1, 2-dimethyl-hydrazine(DMH)-treated young or adult rats. 26 rats(Wistar, 14 young rats weighting approximately 130~180gm and 12 adult rats weighting approximately 500~550gm) were given subcutaneously once weekly with 20mg of DMH/kg body weight(BW)/week for 8~22 weeks. Individual body weight were recorded weekly at the same day and time. The rats were killed at 8, 13, 15. 17, 19, 21 and 22 weeks. The intestinal tracts were opened longitudinally and carefully examined for tumors. The localization, number, and size of tumors were noted. Tumor-bearing areas were dissected out and fixed on neutral buffered 10% formalin and normal-looking mucosa from 8~22 weeks rats were also taken for fixation. Paraffin sections were stained by H-E for histopathological examination or with immunohistochemical stain for bromodeoxyuridine(Brdur) positive cells. 1. The growth proportion of body weight appeared to be decreased in the DMH-treated young rats than in control young rats and body weight of DMH-treated adult rats appeared to be 13.4% or less lower than weighted on 0 week. 2. Macroscopically, the developed tumors in the intestinal tracts were not observed as early as the 13 weeks after DMH treatment. The number of developed tumors per rat was found to be 14.3, 18.8, 22.3 in 15, 17 and 22 weeks. The numbers of tumors in intestinal regions per rat were 2.1, 4.3, 5.4, 2.5 in duodenum, jejunum, ilium and colon on 15 weeks, 2.3, 6.4, 7.8, 2.3, on 17 weeks, and 2.7, 9.3, 9.0, 1.3 on 22 weeks, respectively and the ileum and jejunum were higher in appearance rate of tumors and tumor types are dome shapes and diameter of largest tumor were 6.3mm. 3. Histopathologically, intestinal mucosa were thickened by the irregular distorted and distended crypts following hyperplasia. The tumors developed on the mucosa and submucosa and were recognized to be adenocarcinoma. 4. Immunohistochemically, the labeling index(LI) was calculated as the ratio of the number of Brdur-labeled cells to the total number of column cells of the crypts with longitudinal axis. LI of Brdur positive cells per crypt were 5.6%, 8.0% on small intestine of control and 22 week group, respectively and 3.7%, 12.7% on large intestine of control and 22 week group, respectively and were appeared to be increase in 22 week group than in control group and to be more number of proliferating cells in 22 week group than in control group. 5. LI of Brdur positive cells in 1, 2, 3, 4, 5 segments of crypt column were 11.7%, 10.7%, 3.8%, 0.6%, 0% in small intestine of control group and 23.5%, 11.8%, 2.3%, 2.4%, 0.8% in small intestine of 22 week group, and 5.4%, 7.4%, 3.8%, 1.0%, 0.4% in large intestine of control group and 29.5%, 20.3%, 5.9%, 6.3%, 1.3% in large intestine of 22 week group respectively. So results indicate that the number of proliferating cells by DMH treatment increase and were concentrated on the 1, 2 segments of crypt columns.

Purpose: This study was performed to investigate the effect of induced ametropia on static posture for body balance. Methods: Twenty subjects (10 males, 10 females) of average age $23.4{pm}2.70$ years were participated and ametropia(binocular myopia; BM, simple myopic anisometropia; SMA, binocular hyperopia; BH, and simple hyperopic anisometropia; SHA) were induced with ${pm}0.50D$, ${\pm}1.00D$, ${\pm}1.50D$, ${\pm}2.00D$, ${\pm}3.00D$, ${\pm}4.00D$, ${\pm}5.00D$, respectively. General stability (ST), weight distribution index (WDI), and fall risk index (FI) were measured using TETRAX the biofeedback systems. Each index of the body balance was evaluated for 32 seconds in each ametropic condition and those value was compared with the value in fully corrected condition. Results: The ST showed significant increase from +0.50 D under condition of BM, from +1.00 D under condition of SMA, from -1.00 D under condition of BH, and from -1.50 D under condition of SHA compared with under condition of fully corrected condition, respectively. The FI showed significant increases from +4.00 D under condition of BM, from -1.00 D under condition of BH, and from -1.50 D under condition of SHA. The WDI show no change in all ametropia condition. Conclusions: Whatever ametropia is, uncorrected refractive error could reduce the general stability of body balance and increase the falling risk.

Objectives : The effects of exercise on bone density have been found to be inconsistent in previous studies. We conducted a cross-sectional study in premenarcheal girls to test two hypotheses to explain these inconsistencies. Firstly,'the intensity of mechanical strain, in terms of the ground reaction force(GRF), has more important effects on the bone mass at a weight-bearing site', and secondly, 'calcium intake modifies the bone response to exercise'. Methods : The areal bone mineral density was measured at the Os calcis, using peripheral dual energy X-ray absorptiometry, in 91 premenarcheal girls aged between 9 and 12 years. The intensity of mechanical strain of exercise was assessed by a self-report questionnaire and scored by the GRF as multiples of body weight, irrespective of the frequency and duration of exercise. The energy and calcium intake were calculated from the 24-hour dietary recall. An analysis of covariance(ANCOVA) was used to determine the interaction and main effects of exercise and calcium on the bone density, after adjusting for age, weight, height and energy intake. Results : The difference in the bone density between moderate and low impact exercise was more pronounced in the high than low calcium intake group. The bone density for moderate impact exercise and high calcium intake was significantly higher than that for low impact exercise (p=0.046) and low calcium intake, after adjusting for age, weight, height and energy intake. Conclusions : Our study suggests that the bone density at a weight-bearing site is positively related to the intensity of mechanical loading exercise, and the calcium intake may modify the bone response to exercise at the loaded site in premenarcheal girls.
