This study was conducted to investigate the actual conditions of vitamin supplement usage, the importance of their agents for health management, and the distribution of basic data for their correct consumption. For a period of one month 2003, the study was conducted based on questionnaires to the parents of students in both a middle school and a high school, and the personnel of K Company at random. The material used the survey sheets by setting up the previous investigation. The collected data analyzed the frequency and percentage of the following items: General demographic characteristics of consumers; the supplements taking; the reasons for taking them; the kinds of supplements taken; the media used for distributing data on their use; the potential use in the future, etc. According to the survey, the number of people who were taking supplements was higher than the number of people who weren’t taking them. Multi-vitamins were mostly consumed. The rate of supplements consume was high in people of a higher income bracket, had the time to exercise and to enjoy physical recreation. Most of the consumers who were taking the supplements said they did it to maintain their health and to recover from the fatigue. Those who weren’t taking them said they had enough vitamins from eating the appropriate food, and they were also concerned about the effectiveness of taking the supplements. The majority of useful information or advice for purchasing vitamins came from doctors, medical experts, relatives, and various media sources such as TV, newspapers, and magazines.

The pharmacokinetics and tissue distribution of DA-3030 (recombinant human granulocyte colony-stimulating factor, rhG-CSF, recently manufactured by Dong-A research laboratory of Dong-A Pharmaceutical Company) were compared with reported data in the literature. After intravenous(i.v.) administration of DA-3030, at dose of 5, 10 and 100 $\mu\textrm{g}$/kg to rats, some pharmacokinetic parameters, such as terminal half-lives(1.05, 1.19 and 1.83 hr, respectively) and clearance (84.0, 54.8 and 45.5 mι/hr/kg, repectively), were dose-dependent. This could be due to the saturable metabolism of DA-3030 in rats. Similar results were also reported. After subcutaneous(s.c.) and intramuscular(i.m.) administrations of DA-3030, 10 $\mu\textrm{g}$/kg to rats, the extent of bioavailability(absolute bioavailability) were incomplete; the values were 23.3 and 18.2% after s.c. and i.m. injections, respectively, due to the degradation of DA-3030 by protease. After 7-consecutive day i.v. administrations of DA-3030, 10 $\mu\textrm{g}$/kg/day, to rats, the plasma concentrations and pharmacokinetic parameters of DA-3030 were not significantly different from those in single administration. In mice and dogs at DA-3030 dose of 10 $\mu\textrm{g}$/kg, the plasma concentrations of DA-3030 were also declined rapidly with terminal half-lives of 1.31 and 1.15 hr, respectively. DA-3030 was highly concentrated in the kidney after i.v. administration of DA-3030, 10 $\mu\textrm{g}$/kg, to rats, and the results were similar to those obtained using radiolabelled rhG-CSF in the literature. Above data indicate that DA-3030 has similar properties to rhG-CSF manufactured by other companies in view of pharmacokinetics.

Ostomates have suffered from many difficulties due to their physical, psychosocial handicaps and changes of life style to include ostoma management that influences their daily and quality of life. An appropriate nursing education for ostoma management is very important. Practical educational materials needs revision because those were developed by pharmaceutical companies and hospital institutions. The purpose of this study is to provide more practical and reasonable education materials for ostomates by doing analysis and survey of educational materials now being used. We surveyed 8 types of educational materials used in 23 university hospitals and medical centers in Seoul ; four of them were developed by department of nursing and the remainder by an Ostomy Company Data, collected from July 14, 1997 through July 31, 1997 were analyzed. The results are as follows ; 1. The analysis of education guide, on ostomate included 14 subcategories : introduction, structure and function of gastrointestinal tracts, definition of stoma, types of ostomy, definition of peristalsis, methods of defecation management, selection of instrument, resolution of problems and general situations following surgery, daily life, where to ask for help, explanations for terms, information about where to buy instrument, explanations for enterostomal therapist, a matter of consultation with doctor, etc. 2. Introduction contained specific contents on practical ostomate management that ostomates would experience through their lives. Ostomate education guides were developed 3 hospitals except one which missed this point. 3. Most ostomate education guides, except one hospital, helped ostomates to understand their physical structure changes with specific explanations on gastrointestinal tracts with figures. 4. Six institutions did not talk about the definition of peristalsis. 5. All institutions, except two, helped ostomates to understand types of ostomy with figures. 6. More detailed explanations on natural defecation are needed. The benefits and pitfalls of natural defecation should be more specified. 7 No psychosocial difficulties of ostomy management were addressed. 8. The efficiency of enema can be better understood through all explanations with figures. Some institutions did not mention items about definition, benefits, pitfalls of enema, sequency of enema, how to wash, cautions performing and enema, skin management, cleaning instrument after enema proper time to spend. 9. There were no detailed contents and what to do in case of not being able to do enema. 10. Only one educational material mentioned emotional aspects after the surgrey. 11. Most institutions explained subcategory of daily life but did not provide specific contents on the difficulties of physical, psychological, and sociocultural controls. 12. The subcategory of ureterostomy education guides included explanations on normal structure and function of urinary tracts, types of ureterostomy, how to manage skin, usage and types of instrument, commercial urostomy, how to manage instrument, daily life, introduced the general contents. However, more specific explanations were needed.

DA-5018 is a synthetic capsaicin derivative under development as a non-narcotic a analgesic ag$\varepsilon$nt. DA-50 18 showed a potent analgesic activity against acute and chronic pain m model(Tablel, 2.), but it had a narrow margin of safety. DA-5018 did not bind to opioid(${\kappa}, {\delta}, {\mu}$), NKl, CGRP receptors in vitro and its analgesic effect was not antagonized by naloxone, a and it did not develop analgesic tolerance. In addition DA-5018 had no inhibitory effects against c cyclooxygenase and 5-lipooxygenase activities. DA-5018 significantly increased the relcase of substance P from the slices of the rat spinal cord. These results suggest that DA-50 18 is not a narcotic nor aspirin-like analgesic and the release of substance P is one of analgesic mechanism of action of DA-5018. We found that DA-5018 was almost ten times more potent and was at l least IOO-times less irritable compared to capsaicin. Accordingly development of topical formula was adopted. Topical formula was desiged and screened by flux test of DA-5018 using hairless mouse skin and several formulas were selected. With these topical formulas we a assessed the analgesic efficacy and carried out the toxicity, skin irritation and pharmacokinetic studies. In streptozotocin-induced hyperalgesic rat and 50 % galactose-fed hyperalgesic rat as diabetic pain models, DA-5018 cream increased the pain thresh이ds up to 77.0% and 24.4% respectively, while Zostrix-HP(capsaicin cream) incr$\varepsilon$as cd by 65.9% and 21.0%. DA-5018 c cream showed a good analgesic effect as welI in FCA-induced arthritic rat. DA-5018 cream did not show any toxicological signs in acute and chronic toxicity test and had little skin irritation in car swclIing and scratching t$\varepsilon$st. Pharmacokinetics of DA-50 18 were studied after topical application of ${14}^C$-Iabelled or unlabelIed DA-5018 cream. Plasma and skin concentrations c except applied skin wcre below the dctection limit and after 7-day cummulative application, plasma concentrations were also below detection limit DA-50 18 may have an advantag$\varepsilon$ ov$\varepsilon$r c capsaicin and is now being developed as a topical agent for the treatment of pains. DA-50 18 cream was approved for Korean IND and is now under a Phase II clinical study for arthritic pain a after finising Phase I study. DA-50 18 was also liscensed out to Stiefel Company in America in

In our study, osteoporosis was induced by ovariectomized in female Sprague-Daweley (SD) rats, and the prevention and treatment efficacy of the climacteric disease the ostmenopausal type I pattern was examined by using the experimental substance soybeans and arowroot. No clinical signs and mortality after continuous oral administration of experimental substances for 14 weeks were not observed, however, the weight of experimental animals underwent ovariectomized was increased significantly in comparison with control group (p<0.01). The atrophy of the uterus due to T3 group was 23.64% after 7 weeks, 24.44% after 14 weeks (in comparison with N.C. group), and it was statistically significantly increased. In regard to the change of blood cells, it was observed that platelets were statistically significantly reduced in the ovariectomized group, and administered orally experimental substances continuously for 7 weeks, in all groups administered experimental substances, it was found that platelets had the tendency to be increased more than N. C. group. In regard to He change of blood biochemistry, removed the ovary, the concentration of ALP showed the tendency to be increased than control group, and particularly in T3 group, it was increased significantly. In regard to the concentration of cholesterol, in comparison with negative control group, it was reduced 68% at 7 weeks and 35% at 14 weeks. After ovariectomized, the amount of estrogen was found to be reduced by 21.37% in comparison with control group, it showed the tendency to be increased by 4.49% in T1 group and 7.62% in T2 group, the concentration of estrogen in each group showed the tendency to be increased than negative control group, and in T3 group, it was increased to 100.46% and 117.65% in T4 group, and it was increased more than control group. Based on the above experimental results, in the experimental animals female rats, because of the hormonal imbalance induced by ovariectomized, a large mount of fat is accumulated in the body and due to it osteoporosis, obesity, hypertension, hyperlipidemia, fat of the liver, arteriosclerosis, diabetes, and other metabolic diseases were developed. Hence, when the experimental substance Extraction of ferment arrowroot was orally administered continuously for 14 weeks, it was thought that a certain proportion of the hormonal balance was maintained that functioned as a substance interfering the accumulation of fat, and it was considered to be of help in the treatment of not only osteoporosis Type I, but also for the prevention and treatment of various endocrinal diseases.

DA-6034, a eupatilin derivative of flavonoid, has shown potent effects on the protection of gastric mucosa and induced the increases in fluid and glycoprotein secretion in human and rat corneal and conjunctival cells, suggesting that it might be considered as a drug for the treatment of dry eye. However, whether DA-6034 induces $Ca^{2+}$ signaling and its underlying mechanism in epithelial cells are not known. In the present study, we investigated the mechanism for actions of DA-6034 in $Ca^{2+}$ signaling pathways of the epithelial cells (conjunctival and corneal cells) from human donor eyes and mouse salivary gland epithelial cells. DA-6034 activated $Ca^{2+}$-activated $Cl^-$ channels (CaCCs) and increased intracellular calcium concentrations ($[Ca^{2+}]_i$) in primary cultured human conjunctival cells. DA-6034 also increased $[Ca^{2+}]_i$ in mouse salivary gland cells and human corneal epithelial cells. $[Ca^{2+}]_i$ increase of DA-6034 was dependent on the $Ca^{2+}$ entry from extracellular and $Ca^{2+}$ release from internal $Ca^{2+}$ stores. Interestingly, these effects of DA-6034 were related to ryanodine receptors (RyRs) but not phospholipase C/inositol 1,4,5-triphosphate ($IP_3$) pathway and lysosomal $Ca^{2+}$ stores. These results suggest that DA-6034 induces $Ca^{2+}$ signaling via extracellular $Ca^{2+}$ entry and RyRs-sensitive $Ca^{2+}$ release from internal $Ca^{2+}$ stores in epithelial cells.

Familial Parkinson's disease (PD) has been linked to point mutations and duplication of the ${\alpha}$-synuclein (${\alpha}$-syn) gene. Mutant ${\alpha}$-syn expression increases the vulnerability of neurons to exogenous insults. In this study, we developed a new PD model in the transgenic mice expressing mutant hemizygous (hemi) or homozygous (homo) A53T ${\alpha}$-synuclein (${\alpha}$-syn Tg) and their wildtype (WT) littermates by treatment with sub-toxic (10 mg/kg, i.p., daily for 5 days) or toxic (30 mg/kg, i.p., daily for 5 days) dose of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Tyrosine hydroxylase and Bcl-2 levels were reduced in the ${\alpha}$-syn Tg but not WT mice by sub-toxic MPTP injection. In the adhesive removal test, time to remove paper was significantly increased only in the homo ${\alpha}$-syn Tg mice. In the challenging beam test, the hemi and homo ${\alpha}$-syn Tg mice spent significantly longer time to traverse as compared to that of WT group. In order to find out responsible proteins related with vulnerability of mutant ${\alpha}$-syn expressed neurons, DJ-1 and ubiquitin enzyme expressions were examined. In the SN, DJ-1 and ubiquitin conjugating enzyme, UBE2N, levels were significantly decreased in the ${\alpha}$-syn Tg mice. Moreover, A53T ${\alpha}$-syn overexpression decreased DJ-1 expression in SH-SY5Y cells. These findings suggest that the vulnerability to oxidative injury such as MPTP of A53T ${\alpha}$-syn mice can be explained by downregulation of DJ-1.
