Nitric oxide is a tonically produced vasodilator that maintains blood pressure in the normal animal. The chronic inhibition of nitric oxide synthase (NOS) elicits the hypertension in rats. However, the mechanism of hypertension induced by chronic inhibition of NOS is not clear. Thus, to clarify the mechanism of the occurance of hypertension, the changes in $\alpha$-adrenergic systems in rats treated with NOS inhibitors for 21 days were examined. Chronic administration of L-NAME significantly increased in the basal blood pressure, but chronic administration of 7-nitroindazole did not. Phenylephrine and G-protein stimulator elicited the more potent contraction in the aorta of the L-NAME-induced hypertensive rats. However when the contractile responses by phenylephrine and G-protein stimulator were calculated the proportion to the contraction by 25 mM KCL, there was no difference between the vehicle-treated rats and the L-NAME-treated rats. The density of $\alpha$-adrenergic receptors in aortic tissue was not changed by the chronic inhibition of NOS. These results suggest that hypertension induced by chronic inhibition of NOS is due to the inhibition of eNOS and the increased responses to the adrenergic drugs are due to the changes of the intracellular contactile mechanism of aortic tissue rather than the changes of receptor density.

With a view to providing basic data for designing male's and female's clothes, healthy males and females(five each) were exposed to three different environmental temperature($20{\pm}1.0^{\circ}C$, $28{\pm}1.0^{\circ}C$, $32{\pm}1.0^{\circ}C$) in the nude. Their adaptation of skin temperature, physiological responses( rectal temperature, blood pressure, pulse rates) and psychological reactions(thermal, comfort and perceptive sweaty sensations) were analyzed as follows; The subjects's skin temperature had a similar look of adaptation, but the stability of skin temperature differed at tha $20{\pm}1.0^{\circ}C$ and at the $28{\pm}1.0^{\circ}C$ Males had higher skin temperature at three environmental temperatures, but females showed a higher temperature change at the $20{\pm}1.0^{\circ}C$ and $28{\pm}1.0^{\circ}C$ and males at the$32{\pm}1.0^{\circ}C$ Thus females were more resistant to the cold, while males were more resistant to the heat. As environmental temperature increased, rectal temperature and pulse rates also grew up. Females turned higher in rectal temperature and lower in blood pressure, but both sexes had a normal range of physiological reactions. Even though three environmental temperatures were same changes in thermal sensation at $28{\pm}1.0^{\circ}C$and in perceptive sweat sensation at $32{\pm}1.0^{\circ}C$, two sexes had the same response in comfort sensation at the three environmental temperatures.

Purpose: The purpose of this study was to compare the effectiveness for infants of antifebrile therapy using a hypothermia blanket or rectal antipyretics following open heart surgery. Methods: This was a retrospective study and 174 infants who had open heart surgery at P University Hospital, and whose body temperature body temperature exceeded $37.2^{\circ}C$ were included in the study. The assessment tool was composed of 32 items was used for assessment of fever therapy, physiological indexes and antifebrile duration. Physiological indexes included systolic blood pressure, diastolic blood pressure, heart rate, pH, $PaCO_2$, $PaO_2$, $HCO_3{^-}$, $SaO_2$, and $K^+$ and the antifebrile duration was minutes from having a fever until BT returned to normal levels. Results: The antifebrile duration with the hypothermia blanket was shorter than with rectal antipyretics. There were significant differences in the physiological indexes with either type of antifebrile therapy, but drop in BT was greater with the hypothermia blanket than rectal antipyretics. Conclusion: The results of this study indicate that a hypothermia blanket is a non-invasive, non-drug and safe antifebrile therapy. Therefore, a hypothermia blanket can be applied to infants with a fever following open heart surgery.

Purpose: This study aimed to examine the compliance to a low-salt diet, sodium intake, and preferred salty taste in elderly patients with hypertension. Methods: A cross-sectional descriptive design was used. Participants were 105 elderly patients with hypertension living in a rural area. The compliance with a low-salt diet, sodium intake, and preferred salty taste, blood pressure, body mass index, and waist circumference were measured, and compared according to the general characteristics and the levels of blood pressure. Descriptive statistics, $X^2$-test, t-test, and ANOVA were used for data analysis. Results: compliance with a low-salt diet was marginally elevated. Sodium intake was relatively high and the main sources were seasonings and vegetables. The participants tended to prefer high levels of salt. Sodium intake was significantly higher the hypertensive individuals (stage I and II) compared to prehypertensive subjects on a normal maintenance diet. Sodium intake from vegetables was also significantly different between the two groups. Conclusion: Nursing intervention for hypertensive elderly patients should include strategies to decrease sodium intake.

It has been reported by some investigators that pressor response of rabbits to sympathetic ganglionic stimulants was weak. In this paper it was attempted to investigate this problem more thorouglhy in urethane anesthetized rabbits. 1) In rabbits the approximate doses to elicit increase of about 20 mmHg of blood pressure were $100\;{\mu}g/kg$ with DMPP, $50\;{\mu}g/kg$ with Wy-615, $500\;{\mu}g/kg$ with TMA and with nicotine. The pressor activity of these substances was markedly augmented by treating animals with syrosingopine. 2) In adrenal-ligated rabbits pressor activity of the substances was markedly reduced. Treating the adrenal-ligated animals with syrosingopine augmented significantly the pressor activity of these substances except DMPP. Direct injection of DMPP and TMA into the adrenal produced mole pressor response than intravenous injection did. These date suggest that DMPP has greater effect on the adrenal medulla than the other substances. 3) In vagotomized and atropinized rabbits the pressor activity of these compounds was more marked than in normal rabbits. 4) The above facts indicate that the pressor activity of the ganglionic stimulants in rabbits was definitely low than in cats and dogs. The low responsiveness of the rabbits to these agents was discussed in the light of catecholamine releasing mechanisms, and extraganglionic actions of these substances.

The pharmacological effects of hydrocooked extracts of crucian carp have been investigated. All of the hydrocooked extracts showed the contractile effect on the isolated rat duodenum and decreased to a certain extent the normal blood pressure in anesthetized rat. The hydrocooked extracts also exhibited a dose-dependent relaxation on the isolated rat aorta precontracted with 50 mM KCl. All of these except for RM 60 fraction haying cytotoxic effect against MCF-7 human breast cancer cell showed neither antibacterial activity nor antitumor activity. In addition, we found that although body weight gain in the hydrocooked extracts treated group were all reduced significantly compared to control group, there were no significant changes in the hematological parameters, except that the levels of high-density lipoprotein was significantly increased. These results suggest that the hydrocooked extracts of crucian carp may contain a variety of bioactive materials.

Objectives: Two historical evidence supported the concept of Gamrosu. The first one was Jeho-tang, a selected thirst quencher in Chosun Dynasty and the second one was Saeng-Maek-san, Dongeuibogam's recommendation as one of the qi-vigorating summer beverages. Gamrosu is a modified fasting therapy beverage which is manufactured from those two prescriptions and the carbohydrates (420.6 kcal/d). A retrospective observational study was conducted to evaluate the clinical outcomes. Methods: Thirty-three cases were reviewed at three local Korean Medical clinics that each site's participant has finished the modified fasting for 10 consecutive days. Clinical outcomes were reviewed at pre- and post-fasting sessions by retrieving the changes of body composition, blood pressure, blood chemistries & urine tests, and subjective symptoms & fatigue scores. Results: Demographics of the observed participants were 17 of male and 16 of female. Post-Gamrosu session, -6.89% of body weight, -8.97% of body fat mass were reduced with the nutrition indices being improved (P<0.001). -8.72% of systolic blood pressure, -39.86% of serum triglyceride, -6.75% of fast blood sugar and -8.12% of waist circumference were improved (P<0.05). The levels of high sensitivity C-reactive protein (-58.34%), CRP (-43.55%) and eosinophil (-21.30%) showed the significant diminished profiles (P<0.05). Liver/kidney functions and the standard of electrolytes were maintained within normal range in stable manners. The fatigue scale scores indicated significant lower scores. Conclusions: Taken together, obesity-related clinical outcomes after a modified fasting therapy with Gamrosu were sufficiently feasible and the observed findings should be considered for further prospective clinical studies.

A great deal of attention has been paid to the quality of life in citizens due to the increased number of long term life expectancy. reported as effective in the health promotion of the senior citizens. In this study, the principal investigator developed an exercise program for the senior citizens, which could be educated and managed by nursing staff. This kind approach may support the need of exercise program on regular base via the social organization, which may mean the intentional change of life style. The exercise program consisted of exercise, health education, and a direct the population of the senior A regularexercise has been nursing care. A quasi -experimental study was conducted to investigate the effects of excercise program on health of the elderly in senior citizen's center. Independent variable was a 9 weeks exercise program. Dependent variables were: 1) physical health [e.g. physical fitness(cardiopulmonary endurance, back muscle strength, grip strength, muscular tolerance, flexibility and body fat proportion), physiologic parameters(blood pressure, pulse, respiration. and blood glucose), and perceived physical health status; 2) mental health measured by depression score; and 3) cognitive perception of exercise measured by usefulness and self-efficacy. A total of 37 subjects was randomly assigned into either the control group (without the exercise program: n=18) or the intervention group(with the exercise program: n=19). The results of the study analyzed using a SAS, were as follows: 1) In physical fitness of physical health, there was a significant improvement in cardiopulmonary tolerance. back muscle strength. muscular tolerance and flexibility in the intervention group, compared to the control group, while no difference in grip strength and body fat proportion. The exercise program resulted in decreases in blood pressure, pulse, respiration and blood glucose within normal range and improvement of perceived physical health status in the intervention group. 2) There was a slight increase of mental health(depression score) in the intervention group compared to the control group. but without statistical significance. 3) There was a significant improvement in cognitive perception of exercise(e.g. usefulness and self -efficacy) in the intervention group, compared to the control group. It was concluded that the exercise program employed in this study was appropriate for women senior citizens and had a positive effect on health in general.

This Study was designed to investigate the mechanism of Mixture of Bambusae Caulis in Liquamen and Bamboo Extract on the change of regional cerebral blood flow (rCBF) and blood pressure (BP) in normal rats, and further to investigate cytokines production in serum of cerebral ischemic rats. Mixture were as follows ; Bamboo Extract extracted with distilled water at 98 $^{\circ}C$ for 3 hrs, Mixture of Bambusae Caulis in Liquamen and bamboo Extracts (MLE) mixed at the ratio 1 to 100 (MLE100), 1 to 50 (MLE50), 1 to 20 (MLE20), 1 to 10 (MLE10), 1 to 5 (MLE5). The results were as follows ; The MLE-induced increase in rCBF was significantly inhibited by pretreatment with indomethacin (1 mg/kg, I.p.), an inhibitor of cyclooxygenase as well as methylene blue (10 $^{\mu}g/kg$, I.p.), an inhibitor of guanylate cyclase. The MLE-induced increase in BP was significantly inhibited by pretreatment with methylene blue. In cytokines production in the serum drawn from femoral arterial 1 hr after middle cerebral artery occlusion, MLE5 significantly increased production of TGF-${\beta}$ and increased production of IL-10, but significantly decreased production of TGF-${\alpha}$ compared with control group. In cytokines production in the serum drawn from femoral arterial 1 hr after reperfusion, MLE5 significantly increased production of TGF-${\beta}$ and IL-10, but significantly decreased production of TGF-${\alpha}$ compared with control group. AS results above. And MLE5 had anti-ischemic effect by inhibiting TGF-${\alpha}$ production, and by accelerating IL-10 and TGF-${\beta}$ production.

Objectives: This research study aimed to determine the effect of Korean medicine treatments on a patient with lumbar disc herniation accompanying polycystic kidney disease. Methods: Acupuncture, herbal medicine, pharmacopuncture, spine decompression therapy, Motion Style Acupuncture Treatment (MSAT), and Chuna were preceded for treatment. We checked the patient's Oswestry Disability Index (ODI), numeric rating scale (NRS), and straight leg raise test (SLRT) on admission and discharge; we also used the NRS and SLRT to evaluate the patient's symptoms on every third day during the hospital stay. Because it is important to manage blood urea nitrogen (BUN), serum creatinine, and blood pressure during the early stage of polycystic kidney disease, BUN and serum creatinine levels were checked weekly while blood pressure was checked every morning. Results: Twelve days after admission, the NRS for lower back pain and right leg pain decreased from 7 to 3 and from 7 to 2, respectively. The ODI value also decreased from 56 to 20 while the SLRT value increased from 30/70 to 60/70. The BUN and serum creatinine levels and the blood pressure readings were all within normal range every time they were checked. Conclusions: The use of Korean medicine treatments resulted in improvements in NRS, ODI, and SLRT on a patient with a herniated lumbar disc herniated who had a past history of polycystic kidney disease; thus, the patient was able to maintaining kidney functioning. Herbal medicine, an alternative method of analgesic anti-inflammatory drugs that has been evaluated as relatively safe on liver and kidney function, could be suggested on a patient with a past history of polycystic kidney disease to maintain kidney function when renal function and blood pressure are monitored.
