The purpose of this study is estimate limits of Korean life expectancy at birth by 'Gompertz growth curse Model', 'Cause-Elimination Model' and Multidimensional models of Senescencee and Mortality'. Data used in Gompertz curve were obtained from all life tables published from 1905 to 1990 in Korea, and life expectancies at birth of eighteen groups were selected at five-year interval in consideration of time-series changes. Data used in Cause-Elimination Model are 'Cause of Death statistics in 1991' published in 1992 by National Bureau of Statistics of Korea and 'life table of 1989' published in 1990 by National Bureau of Statistics, Economic Planning Board of Korea. The materials are all classifiable death data, 119, 253 cases of male and 82, 420 cases of female, which is from 1991 Causes of Death statistics. The cases of death analyzed belong to one of 8 categories; i.e., Infectious and Parasitic Diseases(001-139; with notation of Infectious Diseases), Malignant Neoplasms(140-208), Hypertensive Diseases(401-405), Ischemic Heart Dieases and Diseases of Pulmonary Circulation and Other Forms of Heart Diseases(410-429;with notation of Heart Disease), Cerebrovascular Diseases(430-438), Chronic Liver Diseases and Cirrhosis(571; with notation of Liver Diseases), Injury and Poisoning(800-999) and all other disease. Data used in 'Multidimensional models of senescence and mortality' were life table of 1989 published by National Bureau of statistics, Economic Planning Board of Korea and life table of 1970, 1978-79, 1983, 1985 and 1987. The major findings may be summarised as follows: 1. Estimate equations of Gompertz growth curve using life expectancy at birth during the 1905-1990 period are as the following. Male : y = 88.047697 $\times$ $0.199690^{0.903381x}$ Female : y = 95.632828 $\times$ $0.199690^{0.903381x}$ Limits of life expectancy at birth, which were estimated by Gompertz growth curve, are 88.05 for male and 95.63 for female. 2. The effect on life expectancy at birth eliminationg all causes death is 14.04 years(for male) and 10.86 years(for female). Astonishingly, eliminating the malignant neoplasms increase life expectancy at birth by 2.85 years for male 2.03 years for female in 1991. In table 8 we show the effect on life expectancy at birth of separately eliminating each of the 8 categorical causes of death. The theoretical limit to life expectancy by Cause-Elimination Model is 80.96 for male and 85.82 for female. 3. If the same rate of delay [0.376 year(male), 0.435 year(femable) per calendar year] continued, then life expectancy at birth would reach 74.82(male) years and 84, 10(female) years in 2010. With 14.04-years(male) and 10.86-years(female) effect attributable in 2010 would be 88.86 years(male) and 94.96(femable) years. 4. 'Multidimensional models of senescence and death' permits calculations of the value of the attribution coefficient (B), percent of loss per year of physiologic function. The results of Ro and B during the 1970-1989 period are listed in table 9. Estimate of limit to Korean life expectancy at birth by 'Multidimensional models of senescence and death' is 99.47 years for male and 104.74 years for female in 1989.

Background : Chunghyul-dan is a combinatorial herbal medicine; previous studies reported it had therapeutic effects for microangiopathy, a major part in the progression of small vessel disease, as well as having anti-hypertensive, anti-hyperlipidemic, anti-apoptotic, anti-oxidative, and anti-inflammatory activities. Therefor, we examined the inhibitory effect of Chunghyul-dan on stroke recurrence in patients with small vessel disease. Methods : We prescribed Chunghyul-dan at 600 mg a day to patients with small vessel disease, and monitored stroke recurrence, drug compliances, and adverse effect for 1 year. We then performed follow-up brain MRI to find new vascular lesions after 1 year of Chunghyul-dan medication. For the subjects lost to follow-up, we assessed their prognosis after 1 year by telephone. Results : There were 73 subjects treated with Chunghyul-dan for 1 year; new vascular events were found in 3. Of the 85 subjects lost to follow-up, fifty four could be contacted, and eight of them had stroke recurrence. One year of Chunghyul-dan medication reduced the odds ratio of stroke recurrence by 75% compared to the subjects lost to follow-up and the rate increased to 88%, when adjusted for other relevant risk factors for stroke recurrence. These reductions were much higher than those of aspirin and other kinds of conventional anti-platelets. There was no adverse effect in any of the study subjects. Conclusions : We suggest Chunghyul-dan could be useful for inhibition of stroke recurrence. Further study with a randomized controlled trial is needed to confirm this suggestion.

Clonidine, a centrally-acting antihypertensive agent known to reduce central sympathetic outflow and modulate presynaptic transmitter's release, has shown to suppress central noradrenergic hyperactivity induced by immobilization stress in animals, by decreasing the MAC of halothane and the dose of narcotics required to prevent reflex cardiovascular response to noxious stimuli, and to have potent analgesic properties in humans. These characteristics suggest that clonidine might be a useful adjunct to the anesthetic management of patients with preexisting hypertension. Accordingly, we determined the clinical efficacy and safety on analgesia, sedation and hemodynamic stability in the perioperative period. Thirty patients(ASA physical status II-III) with a history of arterial hypertension, scheduled for elective orthopedic surgery were randomly assigned to two groups. We applied CPA-clonidine patch($6.9\;mg/cm^2$, 0.2 mg delivered daily) or placebo patch to each groups, 48 hours prior to induction of anesthesia. Antihypertensive medication was continued until the morning of the scheduled surgery. All patients received premedication of atropine and lorazepam, and induced anesthesia with thiopental and succinylcholine, and maintained with enflurane and 50% nitrous oxide, while sustaining the BP and pulse rate at acceptable range. For the relief of pain postoperatively, diclofenac and fentanyl were administered intramuscularly on demand. The results were as follows: 1) The change of hemodynamic responses in clonidine group was less compared to the placebo group. 2) Intraoperative anesthetic requirement for enflurane in clonidine group were significantly lower than placebo group. 3) Postoperative analgetic requirement in clonidine group were significantly lower than placebo group. In clonidine group, 5 cases out of 15 cases were required no analgetics, and the incidence of administration of additional fentanyl was decreased to 5 cases, comparing with 10 cases in placebo group.

It is generally accepted that the delivery of health care is undergoing many changes specially those related to acute, contagious disease care and to the increase of chronic illnesses which can not be cured but are controlable. The health care practitioner can not be soley responsible for the control of their clients' care. Because the clients will play a vital role in controlling their illnesses, long term participation by both the health care provider and the client is necessary. Since most individuals with hypertension do not experience signs or symptoms, the disease is difficult to detect and even when diagnosed, clients do not comply well with their hypertension regimens. The noncompliant client is at increased risk for compliants involving the heart, brain, kidney and other organs. In an effort to explore methods of increasing patient participation in and adherence to treatment programs for hypertension, the researcher used health contracting to promote self care. The research questions are; 1) Will the health contracting increase compliance in health behavior and reduce the blood pressure\ulcorner 2) If clients comply with their regimens will this reduce their blood pressure\ulcorner The research design utilized in this study was a quasi-experimental design. A purposive sample, was abtained from two churches in the 1. area, consisting of 64 clients with hypertension. The data was collected from the middle of January to the 1st of September 1985. Randomization was only of the two church groups into experimental and control groups. Compliance with health behavior related to the hypertensive regimen, blood pressure and body weight were measured, compared and analyzed. In the experimental group measurements were made 6 times; one month before the education program after education program when health contracting was done and 4 more times once a month for 4 months. In the control group measurements were made 3 times; one month before the education program after the education program, and once 4 months later. There was no health contracting. The data were analyzed by t-test, Pearson correlation and ANOVA according to purpose of the study. The result of this study may be summarized as follows: The result related to the hypothesis on the effect of health contracting are as follows: H$_1$; “The hypothesis that the experimental group, with a health contractual agreement will demonstrate increased compliance levels for health behavior than the control group” was supported(t＝-5.29, df＝62, p＝.000). H$_2$; “The hypothesis that the experimental group, with a health contractual agreement, will demonstrate a greater reduction in blood pressure than the control group” was supported (for systolic blood pressure t＝2.72, df＝62, p＝.009, for diastolic blood pressure t＝1.95, df＝62, p＝.050). H$_3$; The hypothesis that the greater the compliance of the client with health behavior the lower the client's blood pressure will be was partially supported (for systolic pressure r＝-.2981, p＝.008, for diastolic pressure r＝-.1720, p＝.087). From the examination of the results of this study it can be concluded that the interaction between the nurse and the client, contracting to define goals and reinforcing compliant behavior, leads to improved compliance with health care behaviors and thus to an increase in the effectiveness of nursing care. Further consideration need to be given to the inclusion of the concept of health contracting in primary nursing and to further research in this area.

In order to investigate the pharmacological properties of New Woohwangehungsimwon Pill (NWCH). Effects of Woohwangehungsimwon Pill (WCH) and NWCH were compared using various experimental models. In isolated rat aorta, NWCH and WCH showed the relaxation of blood vessels in maximum contractile response to phenylephrine ($10^{-6}$M) without regard to endothelium containing or denuded rings of the rat aorta. Furthermore, the presence of the inhibitors of NO synthase and guanylate cyclase did not affect significantly the relaxative effects of NWCH and WCH. NWCH and WCH inhibited the vascular contractions induced by acethylcholine, prostaglandin endoperoxide or peroxide in a dose-dependent manner. In conscious spontaneously hypertensive rats(SHRs), NWCH and WCH decreased significantly heart rate. These, at high doses, had a negative inotropic effect that was a decrease of LVDP and (-dp/dt)/(+dp/dt) in the isolated perfused rat hearts, and also decreased the contractile force and heart rate in the isolated rat right atria. In excised guinea-pig papillary muscle, these had no effects on parameters of action potential at low doses, whereas inhibited the cardiac, contractility at high doses. Furthermore, these had a significant inhibitory effects on heart acceleration in normotensive rats and SHRs. These results suggested that NWCH and WCH have weak cardiovascular effects, and that there is no significant differences between two preparations.

There seems to be some controversy about the effect of total ginseng saponin (TGS) on the secretion of catecholamines (CA) from the adrenal gland. Therefore, the present study aimed to determine whether TGS can affect the CA release in the perfused model of the adrenal medulla isolated from spontaneously hypertensive rats (SHRs). TGS (15-150 ${\mu}g/mL$), perfused into an adrenal vein for 90 min, inhibited the CA secretory responses evoked by acetylcholine (ACh, 5.32 mM) and high $K^+$ (56 mM, a direct membrane depolarizer) in a dose- and time-dependent fashion. TGS (50 ${\mu}g/mL$) also time-dependently inhibited the CA secretion evoked by 1.1-dimethyl-4 -phenyl piperazinium iodide (DMPP; 100 ${\mu}M$, a selective neuronal nicotinic receptor agonist) and McN-A-343 (100 ${\mu}M$, a selective muscarinic M1 receptor agonist). TGS itself did not affect basal CA secretion (data not shown). Also, in the presence of TGS (50 ${\mu}g/mL$), the secretory responses of CA evoked by veratridine (a selective $Na^+$ channel activator (50 ${\mu}M$), Bay-K-8644 (an L-type dihydropyridine $Ca^{2+}$ channel activator, 10 ${\mu}M$), and cyclopiazonic acid (a cytoplasmic $Ca^{2+}$-ATPase inhibitor, 10 ${\mu}M$) were significantly reduced, respectively. Interestingly, in the simultaneous presence of TGS (50 ${\mu}g/mL$) and N${\omega}$-nitro-L-arginine methyl ester hydrochloride [an inhibitor of nitric oxide (NO) synthase, 30 ${\mu}M$], the inhibitory responses of TGS on the CA secretion evoked by ACh, high $K^+$, DMPP, McN-A-343, Bay-K-8644, cyclopiazonic acid, and veratridine were considerably recovered to the extent of the corresponding control secretion compared with the inhibitory effect of TGS-treatment alone. Practically, the level of NO released from adrenal medulla after the treatment of TGS (150 ${\mu}g/mL$) was greatly elevated compared to the corresponding basal released level. Taken together, these results demonstrate that TGS inhibits the CA secretory responses evoked by stimulation of cholinergic (both muscarinic and nicotinic) receptors as well as by direct membrane-depolarization from the isolated perfused adrenal medulla of the SHRs. It seems that this inhibitory effect of TGS is mediated by inhibiting both the influx of $Ca^{2+}$ and Na+ into the adrenomedullary chromaffin cells and also by suppressing the release of $Ca^{2+}$ from the cytoplasmic calcium store, at least partly through the increased NO production due to the activation of nitric oxide synthase, which is relevant to neuronal nicotinic receptor blockade, without the enhancement effect on the CA release. Based on these effects, it is also thought that there are some species differences in the adrenomedullary CA secretion between the rabbit and SHR.

혈관 수축력 및 혈압 조절에 관여하는 것으로 알려진 아라키돈산을 물질 대사시키는 CYP2C19 유전자는 최근 심혈관 질환 관련 연구의 새로운 유전자로 제시되고 있다. 본 연구에서는 CYP2C19 유전자의 2 종류 다형성 ($CYP2C19^*2$와 $CYP2C19^*3$)과 고혈압 간의 연관성을 조사하고자 하였다. 연세대학교 의료원 심장혈관병원에서 수집한 1,241명(환자군: 537명, 대조군: 704명)을 대상으로 $SNaPShot^{TM}$ assay를 이용하여 유전자형을 결정하였다. 두 종류의 다형성 가운데 $CYP2C19^*3$의 대립인자형 및 유전자형의 빈도 분포가 환자군과 대조군 간에 유의한 차이를 나타냈다(p=0.019, p=0.023). 다중 로지스틱 회귀분석 결과, dominant model에서, CYP2C193 A 대립인자형은 본태성 고혈압과 매우 유의한 연관성을 나타냈다(OR, 0.723, p=0.032). 또한 CYP2C19 G-A haplotype은 고혈압 발생 위험을 매우 유의하게 감소시키는 것으로 조사되었다(OR, 0.714, p=0.015). 따라서 본 연구 결과는 $CYP2C19^*3$ 다형성이 본태성 고혈압 발생에 대한 보호 효과작용에 관여할 것이라는 증거를 제시하고자 한다.
