Stroke patients have increased with the overall aging of our population, 60 years and older. Recently the number of stroke patients has been on the increase even among younger people in their thirties. The family support is frequently mentioned as a major variable which plays an important role in helping the patients adapt themselves to their hemiplegic situations. The purpose of the study was to examine between family support and activities of daily living(ADLs)abilities for the hemiplegic patients. and to provide the basic data to help the patients carry out their ADLs on their own. The sample for the study included 106 hemiplegic patients and their family members. The data were collected using a focused, structured interviews. The major findings of the study were as follows: 1. The hemiplegic patients perceived that their family supports were very high(Mean, 49.00). 2. The degree of family support was significantly higher in female, high economic status. and non-use of brace patients than in male, poor economic status, use of brace patients. 3. The ADL abilities of the hemiplegic patients were significantly higher in ambulatory. younger. and longer-period-of-illness patients and patients who used a cane as a assistive device. 4. The family support for the hemiplegic patients showed a statistically significant Cor relationship with their performance of ADL(r =.30809. p=0.0013). 5. The performance of ADL for the ambulatory patients were mainly affected by the degree of family support. the period of the hemiplegic illness, the use of brace, informal care giving, and the age. These variables explained 50% of variance. 6. The length of illness was a statistically significant affecting variable for ADL performance in OPD and assistive device in IPD. In conclusion. the higher the hemiplegic patients perceived the degree of family support. the better they performed ADL. We should develop nursing methods which enhance the family support for the hemiplegic patients in order to increase their performance of ADL.

BACKGROUND: A rehabilitation hospital has the characteristics of longer hospital stay, a variety of medical and paramedical personnels involved in treatment, and more probability of the primary care giver being a nonmedical person. The purpose of this study is to describe the characteristics of nosocomial infection in a rehabilitation hospitals METHODS: Surveillance was done in a rehabilitation hospital affiliated university hospital from June to August 1996, May to June 1997, and July to September 1999. Nosocomial infection was investigated by an infection control practitioner (JCP) according to the Center for Disease Control and Prevention (CDC)'s definitions visiting the rehabilitation wards regularly. RESULTS: The overall NI rates were 3.83 in 1996, 4.42 in 1997 and 1.91 in 1999 per 1,000 patient days, and the urinary tract infection (UTI) rates were 2.82 in 1996, 2.87 in 1997 and 1.07 in 1999 per 1,000 patient days. Both of overall NI rate and UTI rate in 1999 decreased significantly compared with that in 1996 and 1997 (P<0.001). Comparing the ward specific NI rate, the average NI rate of the spinal cord injury ward was the highest (5.67 per 1,000 patient days) and that of the pediatric rehabilitation ward was the lowest (0.83 per 1,000 patient days). UTI constituted of the largest proportion of NIs. The distribution of UTI showed a decreasing tendency from 73.47% in 1996 to 56.00% in 1999, but the distribution of gastrointestinal infection showed an increasing tendency from 4.08% and 5.40% in 1997 and 1996 to 24.00% in 1999. The commonly isolated organisms were E. coli (33.63%), Enterococcus spp. (12.73%) and C. difficile (7.27%). It reflected that the main infection was UTI. CONCLUSION: The main NI in rehabilitation hospital was the UTI. It means that the infection control program of rehabilitation hospital should be focused on the control of UTI. Surveillance in the rehabilitation hospital enabled us to describe the characteristics of nosocomial infection in the rehabilitation hospital. NI rate was decreased through continuous communications and educations with factual datum and involvement of various medical and paramedical personnels. These results show that NI surveillance is crucial for an efficient infection control program.

The present study was intended to examine the effect of sodium vanadate on contractility of vascular smooth muscle. Aortic ring preparations were made from the rabbit thoracic aorta and endothelial cells were removed from the ring. The contractility of the aortic ring was measured under various conditions. The results were summarized as follows; 1) Sodium vanadate induced contraction of vascular smooth muscle in a dose-dependent fashion. 2) The contractile effects were not blocked by treatments with adrenergic blocking agent(phentolamine) and indomethacin, indicating the direct action of the drug on vascular smooth muscle. 3) In the presence of ouabain, Na(+)-K(+)-ATPase inhibitor, sodium vanadate still increased the contractility of vascular smooth muscle. 4) Treatment with 4.4'-diisothiocyanostilbene-2.2'-disulfonic acid(DIDS) blocked completely the contractile effects of sodium vanadate. 5) In the presence of verapamil, lanthanum and ryanodine, the contractility of the vascular smooth muscle by sodium vanadate was decreased. From the above results. it was suggested that sodium vanadate acts directly on vascular smooth muscle and causes contraction. It was probably due to inhibition of Ca(++)-ATPase in plasma membrane as well as increasing the release of Ca(++) from sarcoplasmic reticulum and Ca(++) influx across the plasma membrane, but not inhibition of Na(+)-K(+)-ATPase.

Caffeine has been known to induce the contraction of rabbit aortic ring resulting from Ca2+ release from the intracellular stores. But in contrast, contraction of aortic ring induced by depolarizing agents or agonist was reported to be suppressed by caffeine. The present study was intended to examine the effect of caffeine on Ca2+ movement across the plasma membrane and actomyosin ATPase activity of vascular smooth muscle to elucidate the modes of action of caffeine on the vascular smooth muscle. Aortic ring preparation were made from the rabbit thoracic aorta and the endothelial cells were removed from the ring by gentle rubbing. The contractilty of the aortic ring was measured under varying conditions, and Ca2+ influx across the membranes of the aortic ring was measured with Ca2+ sensitive electrode with and without caffeine and the effect of caffeine on actomyosin ATPase activity were measured by modified Hartshrone's method. 45Ca wash out curves with and without caffeine were studied by Richard's method. The results were summarized as follows: 1) Caffeine inhibited the contractilty induced by norepinephrine. high K+, and histamine. but caffeine alone induced a transient contraction of vascular smooth muscle. The caffeine induced contraction was demonstrable even in the absence of external Ca2+. 2) Caffeine increased 45Ca efflux from vascular smooth muscle. 3) In the presence of propranolol, the inhibitory effect of caffeine on epinephrine induced contraction still persisted. 4) Caffeine decreased norepinephrine induced Ca2+ influx through the plasma membranes of aortic ring. 5) Caffeine decreased the actomyosin ATPase activity of vascular smooth muscle. From the above results, it is suggested that caffeine induces the contraction of vascular smooth muscle by release of Ca2+ from intracellular Ca2+ stone, but inhibits drug-induced contraction by decrease of Ca2+ influx across the plasma membranes and a decreased Ca2+ sensitivity of contractile protein in vascular smooth muscle.

Vanadate is a trace element in animal tissues and has been known to inhibit NA(+)-K(+) ATPase in various tissues including skeletal and cardiac muscles and smooth muscles. Vanadate shows contractile actions on various types of smooth muscles. Prolonged dietary administration of vanadate has been shown to cause arterial hypertension, increased peripheral resistance, and a marked reduction of coronary, visceral and renal blood flow.In isolated vascular smooth muscle of aorta, application of vanadate caused contraction. These studies have been conducted the preparation of vascular smooth muscles from which endothelial cell were removed. It has been reported that endothelial cell releases relaxing factor(s) (endothelium-derived relaxing factor, EDRF) in response to acetylcholine and a number of other stimuli and also produces vasoconstrictor substances (endothelium-derived contracting factor, EDCF). The aim of this present experiment is to elucidate whether vascular response of isolated rabbit aorta induced by vanadate are endothelium dependent or not. The result obtained were summarized as follows ; 1) When endothelium was intact, vanadate induced vascular relaxation of aorta precontracted with norepinephrine. But K+ induced contraction was augmented by vanadate in the aorta with or without endothelium. Whereas relaxation produced by vanadate precontracted with angiotensin II was endothelium-independent. 2) Hemoglobin, methylene blue, hydroquinone, and verapamil inhibited vanadate-induced vascular relaxation. But indomethacin and quinacrine had no effect on vanadate induced vascular relaxation. From the above results, it is speculated the vanadate act on endothelium, modifies the synthesis or release of endothelium-dependent relaxing factor and thus changes the contractile responses to norepinephrine in rabbit aorta.

PURPOSE: With the continuous spread of the AIDS virus and other sexually transmitted diseases (STDs) throughout Asia, it has become imperative for HIV/AIDS prevention outreach programs to stress the need for using prophylactics as one form of protection. This is particularly true for commercial sex workers. This pilot study was conducted to investigate the rate of condom use among the commercial sex workers in Korea and reasons why they frequently do not wear condoms during sexual intercourse. METHODS: Fifty female commercial sex workers who worked in the Yong San area were recruited while outreach was performed and forty eight responses were analyzed due to two incomplete questionnaires. The data were collected on June 28, 2004 as part of an outreach program for condom use promotion. RESULTS: The subjects ranged in age from 21 to 45 years. Nearly half of the subjects (47.9%) did not consistently use condoms. The major reason for not using protection was clients'reluctances for using condoms. When condoms were used, the subjects preferred lubricant-rich and less painful condom during intercourse. CONCLUSION: Due to the inconsistent use of condoms, it is clear that many commercial sex workers and clients are susceptible to sexually transmitted diseases. Therefore, it is important to not only educate commercial sex workers, but also to educate their pimps and clientele about the importance of condom use. In general, it is recommended that practical strategies and a policy for condom use promotion be developed.

PURPOSE: The aim of this study was to design and evaluate a scale for measuring the attitudes toward condom use in sexual relationships. METHOD: A questionnaire was administered to 631 college students using a convenience sampling method. The psychometric properties (reliability and validity) were evaluated. RESULT: As a result of the item analysis, 16 items were selected and the internal consistency alpha coefficient was .88. Results indicated that the condom attitude scale is composed of three factors: Interruption of sexual pleasure; Protection; and Image. The three factors accounted for 59.54% of the variance in the total scale. Also, condom attitude was statistically significant (t=7.389, p=.000) between consistent condom users and inconsistent users. CONCLUSION: The results demonstrate that condom attitudes are multidimensional, and the reliability and validity of the scale was supported.

The effects of the alcohol extract of Panax ginseng on the myocardial contractility particularly with respect to Bowditch and Woodworth phenomena and the norepinephrine induced contraction of the vascular smooth muscle were studied in vitro. 1) In the isolated muscle preparation of guinea pig left auricle, the administration of ginseng-alcohol extract at concentrations of 10~50mg% resulted in a significant reduction of both Bowditch and Woodworth effects. 2) In the isolated Ca++ depleted heart of rabbit ginseng-alcohol extract inhibited the Ca++ uptake and the restoration of contractile force during perfusion with a Ca++ containing solution. 3) In the isolated muscle strip of the rabbit aorta noradrenaline (5 X 10-8 g/ml) induced contraction was inhibited by the ginseng-alcohol extract at concentrations of 10~50mg%. From these results it is speculated that the hypotensive effect of ginseng is accounted for by 1) the direct inhibition of myocardial contractility which is resulted from the reduction of Ca++ influx into cardiac cell, and 2) the inhibition of the catecholamine induced contractility of vascular smooth muscles.

Cytosolic Ca2+ concentration of rat ventricular cells was measured under varying experimental conditions by using a fluorescent Ca2+ indicator, Fura-2. Resting [Ca2+]i of rat myocyte was 150 +/- 30 nM (n = 39), and this value was compatible with others. The Perfusion of cardioplegic solution significantly increased [Ca2+]i, and this effect was further augmented by hypothermia (p<0.05). Application of nifedipine (5 x 10(-7) M) to the perfusate or pretreatment of caffeine (10 mM) had no apparent effect on this cardioplegia-induced [Ca2+]i change. But Ni2+ (5 mM), an antagonist of Na+/Ca2+ exchange mechanism, prevented the [Ca2+]i change during cardioplegia (p<0.05). Magnitude of cardioplegia-induced [Ca2+]i increase was also dependent on the Ca2+ concentration of cardioplegic solution. These results suggest that Na+/Ca2+ exchange may play an important role in cardioplegia-induced [Ca2+]i change. To rule out the possibility whether the protective effect of hypothermic cardioplegia is due to the preservation of high-energy phosphate store or decreasing the transmembrane ionic fluxes by phase transition, we exhausted a energy store of cardiac cell by application of 2,4 dinitrophenol to the bath and measured its effect on [Ca2+]i change during cardioplegia. Hypothermic cardioplegia delayed the onset of [Ca2+]i increase and decreased its amplitude compared to those of normothermic cardioplegia. From the above results, hypothermic cardioplegia may protect the cardiac cells from ischemic insult by preserving a high-energy phosphate store. Application of Ni2+ to the cardioplegic solution or reduction of external Ca2+ concentration also had some protective effect, since it prevented [Ca2+]i increase during cardioplegia.
