Cosmetic products including skin and essence were manufactured to analyze the effect of green tea polyphenols addition. In addition, irradiation was applied to remove an undesirable color of green tea polyphenol(GTP), which may cause a problem in the marketing, of a final product; moreover, comparative studies were conducted with the cosmetic products on whether or not antiseptics were treated to verify its use for the development of non-antiseptic cosmetic products. Growth inhibition zones were shown in the microbial study except for Candida albicans. The minimum inhibitory concentration(MIC) of E. coli and C. albicans was 2,500 ppm but that of S. aureus was 1,000 ppm. The numbers of E. coli and S. aureus were reduced to undetected levels when 10,000 and 5,000 ppm of polyphenol were added, respectively. Results indicate that the addition of irradiated green tea polyphenol provides a good method to manufacture functional cosmetics including skin and essence with various biological activities such as antimicrobial activity without antiseptics.

Endothelium-derived relaxing factor (EDRF) activates guanylate cyclase which mediates the formation of cGMP from GTP in vascular smooth muscle. It is well known that endothelium-dependent relaxation is impaired in spontaneously hypertensive rats (SHR). However, it is still unknown whether the impaired endothelium-dependent relaxation in SHR results from the reduced release of EDRF or from the decrease of vascular response to EDRF. We investigated the effects of cGMP on the contractility and Ca movement in the aorta of SHR and Wistar-Kyoto rats (WKY). The amplitude of the endothelium-dependent relaxation to actylcholine (ACh) was significantly less in SHR than in WKY. L-arginine $(10^{-3}M)$ did not increase endothelium-dependent relaxation in both strains. Sodium nitroprusside (SNP), an activator of guanylate cyclase, relaxed the 40 mM $K^+-induced$ contraction in a dose-dependent manner $(10^{-10}{\sim}10^{-6}\;M)$ in the endothelium-rubbed aortic strips of both strains. However, there was no significant difference in these relaxations between WKY and SHR. 8-bromo-cyclic guanosine monophosphate (8-Br-cGMP), a cell membrane-permeable derivative of cGMP relaxed the 40 mM $K^+-induced$ contraction in a dose-dependent manner $(10^{-6}{\sim}10^{-4}\;M)$ in the endothelium-rubbed aortic strips of both strains. Also norepinephrine $(10^{-6}\;M)-induced$ contractions in normal and Ca-free Tyrode's solution were suppressed by the pretreatment with 8-Br-cGMP $(10^{-4}\;M)$ in either strain. However, the amplitudes of suppression induced by 8-Br-cGMP were greater in SHR than that in WKY. Basal $^{45}Ca$ uptake and 40mM $K^+-stimulated\;^{45}Ca$ uptake were not suppressed by pretreatment with 8-Br-cGMP $(10^{-4}\;M)$ in single aortic smooth muscle cells of both SHR and WKY. From the above results, it is suggested that cGMP decreases Ca sensitivity in vascular smooth muscle cells and that the impaired endothelium-dependent relaxation in the aortic strips of SHR is not the result of a reduced vascular response to EDRF.

Coronary artery calcium scores(CACS) has been used as surrogate marker for coronary atherosclerosis. We evaluated 1042 patients who visited the Department of Health Promotion Center in Chonnam National University Hospital and had a test of the CACS from January 2006, to December 2008. This study was performed to evaluate the relation of the CACS with Cadiovascular disease(CVD) risk factors and FRS. CACS and FRS was a significant difference between the group whose calcium score was 0 and the group whose calcium scores were 1 in case of men 2.38(95% CI, 1.83-3.11), women 2.12(95% CI, 1.03-4.35). The age-and sex-adjusted odds ratios for predictor of CVD risk factors to women with age was 1.10(95% CI, 1.06-1.15), HDL-cholesterol was 2.38(95% CI, 1.04-5.44), Fasting plasma glucose was 2.89(95% CI, 1.16-7.21), to men with age was 1.11(95% CI, 1.08-1.14), LDL-cholesterol was 2.12(95% CI, 1.28-3.50), gamma-GTP was 1.73(95% CI, 1.17-2.55), Diabetes mellitus medication was 3.92(95% CI, 1.73-8.89). The CACS seems to be a siginificant factor to evaluate the CVD risk factors.

To improve wellness and quality of life by recognizing the health efforts of stress, the author estimated the relationships between stress, subjective symptoms and clinical diagnosis through a questionnaire and a battery of specified laboratory tests; electrocardiography, blood pressure, cholesterol, aspartate aminotransferase(AST), alanine aminotransferase(ALT), gamma glutamyl transferase$(\gamma-GTP)$, fasting blood sugar, gastro-endoscopy or UGI, abdominal sonography, etc. The data was gathered from 337 clients who were undergoing multiphasic screening program at a University Hospital from January to March 1998. The mean age of subjects was $46.5{\pm}11.2$ years and the mean of body mass index was $24.0{\pm}3.7kg/m^2$. The mean vol of stress was $18.5{\pm}6.0$ expressed as the score out of 40. By general characteristics and lift style among male, mean level of stress was significantly higher in case of lower socioeconomic status, habitual drug use, longer daily working time(>10 hours), no regular exercise, drinkers, irregular meal, skip-ping breakfast(p<0.05). In case of female, that was significantly higher in case of lower education, lowe. socioeconomic status, longer daily working time(>10 hours), no regular exercise, drinkers, smokers, irregular meal, skipping breakfast(p<0.05). Significant correlations were observed between stress and subjective symptoms in all kinds of organ system (p<0.01). Correlation coefficients of stress among male were relatively high with neuro-psychiatric symptom$(\gamma=0.476)$ and cardio-vascular symptom$(\gamma=0.361)$ in order, and correlation coefficients of stress among female was highest with neuro-psychiatric symptom$(\gamma=0.371)$. The prevalence of the diagnosis through the battery of laboratory tests was high in upper gastrointestinal disorders and hypercholesterolemia in order in both sex group. Among male the mean score of stress was significantly high in ulcerative peptic disorder of upper gastrointestine and hepatopathy in order (p<0.05) . Among female that was significantly high in diabetes mellitus. In summary, it is likely that there are associations between stress, subjective symptoms and clinical diagnosis. To promote wellness and quality of life it would be of value that periodic stress evaluation program and stress management including apropriate control of smoking and drinking, regular exercise and meal.

We investigated the effect of ${\alpha}-subunit$ of the stimulatory GTP-binding protein ($G{\alpha}_s$) gene mutation on the expression of the thyrotropin-releasing hormone (TRH) receptor (TRH-R) gene in GH3 cells and in growth hormone (GH)-secreting adenomas of acromegalic patients. In the presence of cyclohexicmide, forskolin and isobutylmethylxanthine, cholera toxin, and GH-releasing hormone (GHRH) decreased rat TRH-R (rTRH-R) gene expression by about 39%, 43.7%, and 46.7%, respectively. Transient expression of a vector expressing mutant-type $G{\alpha}_s$ decreased the rTRH-R gene expression by about 50% at 24 h of transfection, whereas a wild-type $G{\alpha}_s$ expression vector did not. The transcript of human TRH-R (hTRH-R) gene was detected in 6 of 8 (75%) tumors. Three of them (50%) showed the paradoxical GH response to TRH and the other three patients did not show the response. The relative expression of hTRH-R mRNA in the tumors from patients with the paradoxical response of GH to TRH did not differ from that in the tumors from patients without the paradoxical response. Direct PCR sequencing of $G{\alpha}_s$ gene disclosed a mutant allele and a normal allele only at codon 201 in 4 of 8 tumors. The paradoxical response to TRH was observed in 2 of 4 patients without the mutation, and 2 of 4 patients with the mutation. The hTRH-R gene expression of pituitaty adenomsa did not differ between the tumors without the mutation and those with mutation. The present study suggests that the expression of TRH-R gene is not likely to be a main determinant for the paradoxical response of GH to TRH, and that $G{\alpha}_s$ mutation may suppress the gene expression of TRH-R in GH-secreting adenoma. However, a certain predisposing factor(s) may play an important role in determining the expression of TRH-R.

The present study was designed to investigate i) the action of various nucleotides on membrane permeability of rat red blood cell and hepatocyte for $Na^{+}$ and $Rb^{+}$ ii) the characteristics of purinoceptors on these cell membranes. Blood from Sprague-Dawley rats was obtained by carotid arterial cannulation. Red blood cells were then washed 3 times with saline at $4{\circ}C$. Hepatic parenchymal cells were isolated from rat livers by using a modification of the Berry and Friend (1969) method. For the $Na^{+}$ influx studies, isolated RBC and hepatocyte were incubated in incubation medium containing $^{22}Na^{+}0.2\;{\mu}Ci/ml$ at $37^{\circ}C$. After various time intervals samples were removed from the incubation flask and washed out 3 times with ice-cold washing solutions. Cells were destroyed by adding Triton X-100 and TCA solution. After centrifugation, the supernatants were assayed for $^{22}Na^{+}$ by gamma counter. $^{86}Rb^{+}$ was used to simulate $K^{+}$ in these $K^{+}efflux$ studies. Isolated hepatocytes were incubated for 60 min in the loading solution containing $^{86}Rb^{+}\;10\;{\mu}Ci/ml$ at $37^{\circ}C$. After loading, the cells washed out 3 times by centrifugation with washing solution. The cells were incubated in buffer solution at $37^{\circ}C$. At intervals thereafter, samples were removed and centrifuged. The supernatants were analyzed for $^{86}Rb^{+}$ by liquid scintillation counter. The main results of the experiments were: 1) ATP and ATPP increased in both $^{22}Na^{+}$ influx and $^{86}Rb^{+}$ efflux in the red blood cell. Although ADP showed a tendency to increase in RBC membrane permeability for $^{22}Na^{+}$ and $^{86}Rb^{+}$, the changes were not significantly different from the control. 2) The Significant changes in $^{22}Na^{+}$ and $^{86}Rb^{+}$ flux by ATP were also demonstrated in hepatocyte. ATPP and ADP showed a tendency to increase in hepatocyte membrane permeability for both ions. 3) Other nucleoside triphosphates-ITP, GTP and CTP-did not change in membrane permeability for $^{22}Na^{+}$ and $^{86}Rb^{+}$ in RBC and hepatocyte. In conclusion, not only ATP but also ATPP activate purinoceptors and change in membrane permeability for $Na^{+}$ and $K^{+}$. In order to activate purinoceptors on the cell membrane, the nucleotides have to possess intact adenine moiety and three phosphates or more in its molecule.

Objective : The study was performed to evaluate the effect of treatment for thoracolumbar compression fracture by using Bee Venom Acupuncture that is well known for anti-inflammatory and analgesic effect. Methods : We investigated 39 cases of patient with thoracolumbar compression fracture. The patients with thoracolumbar compression fracture were treated at the department of acupuncture & moxibustion of Kyung-Won University Oriental Hospital from 1st January 2001 to 30th August 2002. We selected for two groups. One group was treated by Bee Venom Acupuncture therapy(Bee Venom Acupuncture Group : BAG), the other group was treated by Filiform Acupuncture therapy(None Bee Venom Acupuncture Group : NBAG). Results : 1. The distribution showed female predominance in sex and 70's predominance in age. The largest group was "accidental fall" and the next was "lifting heavy objects" in causes, and within 2 weeks in the duration of disease 2. In the duration of admission, the largest group was within 4 weeks. In regard to level of injury, T12 was found to be most predominant, followed in turn by L1, L2, L5. In regard to grade of clinical symptoms, Grade III was most predominant, followed by Grade II, Grade IV. 3. In the results of treatment, 87.5% were above "Good" in BAG and 47.8% in NBAG. 4. In the result of treatment due to the grade of clinical symptoms, BAG was more excellent than NBAG on the whols grade. 5. In the result of treatment due to duration of admission, the duration of admission was not in proportion to the results of treatment. 6. In the change of lumber flexion, the improvement above $80^{\circ}$ was 50% in BAG and 21.7% in NBAG 7. In the stability of treatment, the BAG and NBAG did't show any detrimental change in GOT, GPT, r-GTP, BUN, creatinine. Conclusions : In the treatment of thoracolumbar compression fracture, the Bee Venom Acupuncture can be regarded as more effective treatment than Filiform Acupuncture in the clinical practice. This is expected to be available for clinical use.
