  • Objectives: The purpose of this study was to examine the health care utilization pattern and its related factors of low-income population with abnormal results through health examination. Methods: Analysed data were collected through a questionnaire survey, which was given to 263 persons who 30 years or over with abnormal results through health examination at Health Center. This survey was conducted in March, 2003. This study employed Andersen's prediction model as most well known medical demand mode and data were analysed through 2-test, and multiple logistic regression analysis. Results: The proportion of medical utilization for thorough examination or treatment among study subjects was 51.0%. In multiple logistic regression analysis as dependent variable with medical utilization, the variables affecting the medical utilization were 'feeling about abnormal result(anxiety versus no anxiety: odds ratio 2.25, 95% confidence intervals 1.07-4.75)', 'type of health security(medicaid type I versus health insurance: odds ratio 2.82, 95% confidence intervals 1.04-7.66; medicaid type II versus health insurance: odds ratio 3.22, 95% confidence intervals 1.37-7.53)', 'experience of health examination during past 2 years(odds ratio 2.39, 95% confidence intervals 1.09-5.21)' and 'family member's response for abnormal result(recommendation for medical utilization versus no response: odds ratio 4.90, 95% confidence intervals 1.75-13.75; family member recommended to utilize medical facilities with him/her versus no response: odds ratio 19.47, 95% confidence intervals 5.01-75.73)'. The time of medical utilization was 8-15 days after they received the result(29.9%), 16-30 days after they receive the result(27.6%), 2-7 days after they received the result(20.9%) in order. The most important reason why they didn't take a medical utilization was that it seemed insignificant to them(32.4%). Conclusions: In order to promote medical utilization of low-income population, health education for abnormal result and its management would be necessary to family member as well as person with abnormal result. And follow-up management program for person with abnormal result through health examination such as home-visit health care would be necessary.

  • This experiment was carried out to investigate the effects of unilateral and bilateral ovariectomy in immature rats on the weight of body, ovary, uterus and adrenal gland and the change of serum FSH and LH level. Ninty Sprague-Dawley female rats, 23${\pm}$2 days old, were divided into 3 groups with 30 heads per group; control, unilaterally and bilaterally ovariectomized group. Each group was subdivided into 6 groups according to 6 experimental periods; day 4, 8, 12, 16, 20, and 24 after operation. Five rats at every 4 days intervals were measured their body weights and sacrificed for the measurement of their ovarian, uterine and adrenal weights and at the same time blood samples were taken for the determination of serum FSH and LH level by radioimmunoassay. The following results were obtained: 1. Body weights in the unilaterally and bilaterally ovariectomized goups were higher than those of control groups during all experimental periods, even though there were no significant differences among the above 3 groups. 2. A significant hypertrophy of the remained ovary in the unilaterally ovariecto mized group was observed from day 16 till day 24 after operation. The ovarian weight; 22.1${\pm}$1.73mg, at day 16 in control group was smaller than the unilaterally ovariectomized group weighing 50.5${\pm}$8.45mg (p<0.01) and the ovarian weights, 75.9${\pm}$2.25mg and 63.3${\pm}$7.08mg ; at day 20 and 24 in unilaterally ovariectomized group were significantly larger than 29.1${\pm}$2.33mg and 26.3${\pm}$1.76mg in control group, respectively (p<0.01 and p<0.05). 3. The uterus of bilaterally ovariectomized group were remarkably atrophied from day 8 after operation as compared with those of control and unilaterally ovariectomized group. The uterine weight at day 24 was 96.7${\pm}$9.15mg for control group, 139.4${\pm}$1.73mg for unilaterally ovariectomized group and 21.7${\pm}$1.08mg for bilaterally ovariectomized group, respectively and there were significant differences among 3 groups (p<0.01). 4. A statistically significant increase ofthe weight of adrenal gland was observed at day 16 in the unilaterally ovariectomized group with 24.4${\pm}$2.58mg against 15.5${\pm}$3.09mg in control group and 13.9${\pm}$1.38mg in bilaterally ovariectomized group (p<0.05). The adrenal gland weight in unilaterally ovariectomized group with 24.7${\pm}$1.63mg at day 20 and 31.2${\pm}$1.62mg at day 24 increased significantly as compared with bilaterally ovariectomized group with 15.1${\pm}$13.11mg at day 20 and 15.6${\pm}$1.76mg at day 24. 5. Serum FSH level of unilaterally ovariectomized group increased remarkably up to 2.97${\pm}$0.37mIU/ml at day 4 after operaton and then decreased gradually. Serum FSH level of bilaterally ovariectomized group were higher than those of control group throughout all experimental periods. 6. Serum LH level ofunitelarally ovariectomized group with 3.17${\pm}$0.32mIU/iml at day 4 and 3.57${\pm}$0.58mIU/ml at day 24 increased noticeably more than those of control group with 1.79${\pm}$0.16 mIU/ml at day 4 and 2.17${\pm}$0.27mIU/ml at day 24 (p<0.05).

  • This study was undertaken to compare the tooth and arch size between crowding patient and normal subjects. Two group of dental casts were selected on the basis of crowding patients and normal subjects. One group, consisting of 40 pair of dental casts(20 male and 20 female), exhibited noncrowded dentitions. A second group, consisting of 40 pairs of dental cast(21 male and 21 female), exhibited remarkably crowding need for orthodontic treatment. Tooth width measurements were made with a sliding digital caliper with Vernier scale neared 0.01 mm. Mean, standard deviation, T-test of the following parameters were used to compare two group : individual mesiodistal crown widths, arch width and arch length. The following result were obtained. In the mesiodistal crown widths, normal subjects had generalized larger teeth than Wheeler's results(human tooth size index), except for maxillary central incisor, maxillary 2nd premolar, mandibular canine, and mandibular 1st molar. In the orthodontic patients with crowded dentitions, the mesiodistal tooth crown widths were generalized larger teeth than noncrowded normal subjects. In the arch width and arch length, the crowded dentition group had smaller arch width and arch length than the normal group.

  • The study was performed through questionnaire to determine purchase characteristics and consumers' satisfaction for Hanwoo beef for 400 residents in Busan, Gyeongsangnam-do, Daegu and Gyeongsangbuk-do. The results obtained from 363 consumers excluding 37 improperly answered ones were statistically analyzed. The properly answered consumers were classified according to gender, 107 (29.5%) male, 256 (70.5%) female, and ages, 70 (19.3%) twenties, 97 (26.7%) thirties, 131 (36.1%) forties, and 65 (17.9%) over fifties. Consumers having older ages purchased Hanwoo beef more frequently (p<0.05), and Hanwoo specialty shop operated by farmers cooperative was the most popular purchasing sources. Consumers' favorite retail cuts for Hanwoo beef were in the order of loin (43.5%), ribs (22.9%), tender loin (10.5%), brisket (9.9%), round, fore (4.7%), others (3.3%), chuck (2.8%), strip loin, rump (2.5%). For the experiences of purchasing imported beef, 24.55% and 22.3% of consumers answered for 'sometimes' and 'yes', respectively, for the reason of 'low price' (73.3%). Consumers answered 'sometimes' (69.1%) for the question of disguisement of imported beef to Hanwoo beef, and thought traceability (61.7%) and country of origin (17.1%) would be the most effective methods to prevent disguisement. Percentages of responses were 61.1% and 75.5% for traceability and country of origin, respectively, under the assumption of consumer's trustworthiness of above 70%. Prerequisites for Hanwoo beef to succeed as a brand were in the order of taste (3.90 points), consumers' satisfaction (3.28 points), consumers' trustworthiness (3.20 points), safety (3.03 points). Consumers' satisfaction is influenced by the age, academic background and the occupation (p<0.05). Safety is expected to show the difference by the educational background (p<0.05) and the occupation (p<0.01), whereas consumers trustworthiness is influenced by the educational background and income (p<0.05). From the results obtained in the current study, it is concluded that traceability and country of origin is essential to gain consumers' satisfaction and trustworthiness, and that the most important factors for branding Hanwoo beef would be taste and safety.

  • Fluxapyroxad is classified as carboxamide fungicide that inhibits succinate dehydrogenase in complex II of mitochondrial respiratory chain, which results in inhibition of mycelial growth within the fungus target species. This study was carried out to assure the safety of fluxapyroxad residues in agricultural products by developing an official analytical method. A new, reliable analytical method was developed and validated using High Performance liquid Chromatograph-UV/visible detector (HPLC-UVD) for the determination of fluxapyroxad residues. The fluxapyroxad residues in samples were extracted with acetonitrile, partitioned with dichloromethane, and then purified with silica solid phase extraction (SPE) cartridge. Correlation coefficient($R^2$) of fluxapyroxad standard solution was 0.9999. The method was validated using apple, pear, peanut, pepper, hulled rice, potato, and soybean spiked with fluxapyroxad at 0.05 and 0.5 mg/kg. Average recoveries were 80.6~114.0% with relative standard deviation less than 10%, and limit of detection (LOD) and limit of quantification (LOQ) were 0.01 and 0.05 mg/kg, respectively. All validation parameters were followed with Codex guideline (CAC/GL 40). LC-MS (Liquid Chromatograph-Mass Spectrometer) was also applied to confirm the analytical method. Base on these results, this method was found to be appropriate fluxapyroxad residue determination and can be used as the official method of analysis.

  • By the standards and specifications for hygiene products, three test methods for formaldehyde are specified for each item type of hygiene product. After derivatization using acetylacetone and 2,4-dinitrophenylhydrazine (2,4-DNPH), formaldehyde is analyzed by spectrophotometer and high-performance liquid chromatography (HPLC). Validation of the three test methods was performed on tissue, diaper lining and waterproof layer, and panty liner products. The results of linearity (R2), limit of detection (LOD), limit of quantification (LOQ), recovery rate (%) and reproducibility (%), showed that all three methods are suitable for analyzing formaldehyde in hygiene products. After derivatization with 2,4-DNPH and cetylacetone, formaldehyde was analyzed at 0, 3, 6, 9, 24 and 48 hours by HPLC. Formaldehyde derivatized with 2,4-DNPH showed no statistically significant change in formaldehyde peak area over time (P>0.05). But, acetylacetone-derivatizated formaldehyde showed a negative correlation coefficient (r) over time (P<0.01). We investigated the residual amounts of formaldehyde in 205 hygiene products distributed in Busan. Among 74 disposable diaper products tested, 73 had low concentrations of formaldehyde (0.13-29.87 mg/kg). Moreover, formaldehyde was not detected in any of 78 tissue, 27 disposable paper towel, 12 disposable dishcloth, 7 paper cup, one brand of paper straw and 6 disposable napkin products.

  • Purpose : This study was aimed to evaluate the changes of immunologic parameters during hospitalization, and the relationship between IgG and other laboratory or clinical indices in patients with acute poststreptococcal glomerulonephritis (APSGN). Methods : We reviewed the medical charts of 36 children with APSGN who showed ASO titer>250 Todd U/L and C3<70 mg/dL. We evaluated the levels of IgG and other laboratory parameters including C3 and ASO at admission and at discharge (14 cases). Results : The mean age of APSGN patients was $7.5{\pm}2.6$ year of age, and male-to-female ratio was 2.3:1. At presentation, hypertension (systolic blood pressure>125 mmHg), gross hematuria, and weight gain were observed in 27.8% (10/36), 80.1% (29/36), and 80% (24/30) of the patients, respectively. The mean IgG level was $1,432{\pm}322$ mg/dL ($1,025{\pm}234$ mg/dL in control group, P<0.001), and C3 and ASO levels were $26.1{\pm}16.1$ mg/dL and $1,068{\pm}730$ Todd U, respectively. There were no correlation between IgG level and the levels of any of the parameters analyzed (ASO, C3, BUN, creatinine and white blood cell count), and the severity of the disease assessed by the weight-change during admission. The patients aged<6 years of age (10 cases) had less degree of the weight-change, compared to those of the patients aged>8 years of age (15 cases) (-0.6% vs. -5.7%, P=0.01). The IgG and ASO levels did not change, but C3 (P=0.001) and IgM (P=0.02) levels increased during admission. Conclusion : Increased IgG and ASO levels in APSGN did not change, but C3 level increased during admission. IgG level was not correlated with other laboratory parameters (ASO and C3) and the severity of the disease. Younger children seem to have less severe clinical course compare to older children. With our hypothetic pathogenesis of APSGN, further studies are needed to resolve the pathogenesis of the disease including the increase of IgG.

Direct Action of Genistein on the Hypothalamic Neuronal Circuits in Prepubertal Female Rats : Estrogen Receptor Beta($ER{\beta}$) Pathway? (미성숙한 암컷 흰쥐 시상하부의 신경회로에 미치는 Genistein의 직접 작용 : 에스트로겐 수용체 베타아형 경로?)

  • Some phytoestrogens in soy and red wine, for example, might have beneficiary rather than adverse effects. In particular, dietary soy intake seems to be highly correlated with protection of breast cancer, osteoporosis and cardiovascular disorders. However, questions persist on the potential adverse effects of the main soy constituent genistein (GS) on female reproductive physiology. Previously we found that prepubertal exposure to GS could activate the reproductive system of immature female rats leading to precocious puberty onset, and intracerebroventricularly (ICV) injected GS could directly activate hypothalamic kisspeptin-GnRH neuronal circuits in adult female rats. The present study was performed to examine the hypothalamus-specific GS effects in prepubertal female rats and which subtype of estrogen receptor is mediated in this GS effect. Prepubertal female rats (PND 30) were anaesthetized, treated with single dose of GS (3.4 ${\mu}g$/animal), and sacrificed at 2 hrs post-injection. To determine the transcriptional changes of reproductive hormone-related genes in hypothalamus, total RNAs were extracted and applied to the semi-quantitative reverse transcription polymerase chain reaction (RT-PCR). ICV infusion of GS significantly lowered the transcriptional activities of mTOR (1:$0.361{\pm}0.058$ AU, p<0.001) but increased that of GAD67 (1:$1.285{\pm}0.099$ AU, p<0.05), which are known to act as an upstream modulator of kisspeptin and GnRH neuronal activities in the hypothalamus, respectively. GS administration enhanced significantly the mRNA levels of KiSS-1(1:$1.458{\pm}0.078$ AU, p<0.001), and exerted no effect on the mRNA level of kisspeptin receptor GPR-54 (1:$1.29{\pm}0.08$ AU). GnRH gene expression was significantly decreased in GS-treated group compared to control group (1:$0.379{\pm}0.196$ AU, p<0.05). There was no difference in the mRNA level of $ER{\alpha}$ in the GS-treated group compare to control group (1:$1.180{\pm}0.390$ AU, Fig. 3A). However, icv infusion of GS significantly increased the transcriptional activities of $ER{\beta}$ (1:$4.209{\pm}0.796$ AU, p<0.01, Fig. 3B). Taken together, the present study indicated that the acute exposure to GS could directly alter the hypothalamic GnRH modulating system in prepubertal female rats. Our study strongly suggested the involvement of $ER{\beta}$ pathway in GS's hypothalamus-specific action, and this idea is consistent with the GS's well-known $ER{\beta}$-mediated protective action in breast cancer.
