Purpose : Intravenous infusion of albumin has been widely und to relieve severe nephrotic edema in spite of beneficial or harmful effects. The purpose of this study is to examine the harmful effect of albumin on the clinical course of steroid sensitive nephrotic syndrome(SSNS). Method : We prospectively randomized the patients with nephrotic syndrome(biopsy proven or clinically compatible to minimal change nephrotic syndrome) into the albumin group(20$\%$ albumin 1 g/kg) or control group(5$\%$ D/W) between March 1997 and September 1999 at Ewha University Mokdong Hospital. We compared the clinical course of the albumin group(n=13) with the control group(n=13). Results : 1. The duration of steroid therapy until complete remission in the albumin group was significantly longer than the control group($13.7{\pm}6.4\;days\;vs\;7.5{\pm}2.8\;days$)(P<0.05). 2. The remission duration to the first relapse was significantly shorter in the albumin group ($94{\pm}63.5$ days) than the control group($190{\pm}106.4$ days)(P< 0.05). There was no significant difference in the relapse rate within 1 year after complete remission[77$\%$ (10/13) vs 46$\%$ (6/13)](P>0.05) and the relapse frequency per year($1.9{\pm}0.8\;vs\;1.5{\pm}0.5$) between the albumin and control groups. 3. Spot urine protein/creatinine ratio significantly increased in the albumin group at post-albumin 2, 4 days(P<0.05). There was no significant difference in the change of the daily percent weight loss, blood pressure, serum Na, K concentration between the albumin and control groups. Conclusion : Albumin infusion in SSNS delayed the response to steroid and shortened the remission duration to the first relapse. Albumin should be carefully used in nephrotic edema.

Background: Endothelin(ET) is the most potent vasoconstrictor and bronchoconstrictor. The plasma ET-1 level is elevated in patients with acute pulmonary thromboembolism(APTE). This finding suggest that ET-1 may be an important mediator in the cardiopulmonary derangement of APTE. But whether ET-1 is a pathogenic mediator or a simple marker of APTE is not known. The role of ET-1 in the pathogenesis of cardiopulmonary dysfunction in APTE(delete) was investigated through an evaluation of the effects of $ET_A$-receptor antagonist on APTE. The increase in local levels of preproET-1 mRNA and ET-1 peptide in the embolized lung was also demonstrated. Methods: In a canine autologous blood clot pulmonary embolism model, $ET_A$-receptor antagonist(10 mg/kg intravenously, n=6) was administered one hour after the onset of the embolism. Hemodynamic measurements, blood gas tensions and plasma levels of ET-1 immunoreactivity in this treatment group were compared with those in the control group(n=5). After the experiment., preproET-1 mRNA expression(using Northern blot analysis) and the distribution of ET-1(by immunohistochemical analysis) in the lung tissues were examined. Results: The increases in pulmonary arterial pressure and pulmonary vascular resistance of the treatment group were less than those of the control group. Decrease in cardiac output was also less in the treatment group. Complications such as systemic arterial hypotension and hypoxemia did not occur with the administration of $ET_A$-receptor antagonist The plasma level of ET-1 like(ED: what does 'like' mean?) immunoreactivity was increased after embolization in both groups but was significantly higher in the treatment group. The preproET-1 mRNA and ET-1 peptide expressions were increased in the embolized lung. Conclusion: ET-1 synthesis increases with embolization in the lung and may plays play an important role in the pathophysiology of cardiopulmonary derangement of APTE. Furthermore, $ET_A$-receptor antagonist attenuates cardiopulmonary alterations seen in APTE, suggesting a potential benefit of this therapy.

Studies were conducted to determine whether reduced renal blood flow (RBF) exhibited by rats with uncontrolled, streptozotocin (STZ)-induced diabetes is attributable to diabetes-associated, enhanced renal vasoconstrictor influence of endogenous thromboxane $(TX)A_2$. Rats which were injected with STZ after pretreatment with 3-O-methyl glucose (3OMG), an agent which prevents STZ-induced hyperglycemia, were also studied. Basal values of total RBF (RBF; ml $min^{-1}$ $gKw^{-1}$; electromagnetic flow probe), systemic arterial pressure (BP; mm Hg) and renal vascular resistance (RVR;BP $RBF^{-1})$in pentobarbital-anesthetized rats during a control period were $5.9{\pm}0.3$(P<0.1_{VS}. CR), $115{\pm}3$ and $20.3{\pm}1.0$(P<0.1_{VS}. CR) for STZR (n=15), and $8.4{\pm}0.4$, $123{\pm}3$ and $15.1{\pm}0.8$ for age-matched control rats (CR; n= 15), respectively. Basal values of RBF, BP and RVR in 3OMG pretreated STZR were identical to CR. In preparations shown capable of renal vasodilatation, OKY 1581 (1 mg/kg, i.v. followed by 0.4 mg/kg min infusion) abolished arachidonate-induced $(TX)A_2$ synthesis, but did not alter basal BP, RBF or RVR in either STZR or CR (n=4/group). Similarly, i.r.a. infusion of SQ29548 (100 ng/ml RBF) abolished renal vasoconstriction induced by a TX/prostaglandin endoperoxide mimic, U46619, but had no discern able affect on RVR in either STZR (n=8) or CR (n=8). The data indicates that $TXA_2$ does not participate in the elevated basal RVR of STZR which are associated with the diabetic state.

Hypertension is the most frequent disease of chronic circulatory diseases and major intermediate cause or risk of the cerebrovascular disease which is a leading cause of death in Korea. Therefore, management of hypertension is an important issue in Korean healthcare. Especially, therapeutic compliance of hypertensives is very important because the hypertensive patients should receive anti-hypertensive treatment as long as the condition exists. However, many patients drop out of treatment, which is a major problem that needs to be solved through a hypertension control program. This study was carried out to provide basic data and counter measule for the hypertension control program in the community which aimed to keep the patients receiving treatment continuously. In order to investigate compliance of hypertensive patients during three months follow-up and the rate of control of hypertension, the data were collected during February, 2001, by reviewing medical records of 295 hypertensive patients who had been registered to Gunnam-myeon health subcenter before November, 2000. The author also study the dropout reasons by interviewing 58 patients among 68 dropout patients. The results were as follows: 1. Among the 295 subjects, 108(36.6%) were male and 187(63.4%) were female. Statistically, female hypertensives had a higher mean age than male(64.6 vs 66.3, p<0.05). 2. The 54.9% of the patients took anti-hypertensive medicine continuously for the past three months. And 19.3% had drug intermittently, and 25.8% dropped out of treatment. 3. Among several variables, such as sex, age, health insurance, the time taken from a patient's village to the health subcenter, only the last one was found to be significantly related to therapeutic compliance in the contingency table analysis. 4. The dropout reasons by multiple response were as follows, 'no symptom or no problem' (23.9%), 'change to other hospitals'(19.4%), 'geographical barrier'(17.9%), 'change to a neighborhood drugstore' (14.9%), 'immobility'(7.5%), 'economic barrier'(6.0%), 'unsatisfactory services of the health subcenter'(4.4%). 5. The mean blood pressure of 295 subjects was $144.9{\pm}12.9/86.88{\pm}8.6mmHg$. 6. The 32.5% of the subjects were controlled below 140/90mmHg. Conclusions: In order to improve the low rates of treatment and control of hypertension in rural hypertensives, a more active and systematic hypertension control program, including out-reaching follow-up management, is required in rural area. Especially, for health education of hypertensive patients, emphasis should placed on correcting wrong attitude toward hypertension.

Purpose: Propranolol is known to decrease portal pressure by reducing blood flow of portal vein. Perrectal portal scintigraphy with Tc-99m pertechnetate has been introduced to evaluate the portal circulation and early diagnosis of liver cirrhosis. We evaluated the effects of propranolol on portal circulation by using per-rectal portal scintigraphy. Materials and Methods: We analyzed the portal hemodynamics by per-rectal portal scintigraphy in 51 patients with liver cirrhosis, 10 chronic hepatitis and 10 normal subjects. 38 patients with cirrhosis underwent per-rectal portal scintigraphy before and after propranolol medication. Perrectal portal scintigraphy was performed after per-rectal administration of 370 MBq of Tc-99m pertechnetate. The shunt index was calculated as the ratio, expressed as a percentage of heart radioactivity to the sum of heart and liver radioactivity during the first 30 seconds. Results: The shunt index in 40 patients with cirrhosis ($59.8{\pm}27.2%$) was significantly higher than that of normal control ($5.0{\pm}1.2%$. p<0.01) and chronic hepatitis ($11.4{\pm}3.5%$, p<0.01). Shunt index was significantly different according to Child's classification and the degree of esophageal varix (p<0.01). After propranolol medication, shunt index was significantly decreased from $59.9{\pm}27.3%$ to $51.3{\pm}15.3%$ (p<0.01) in 38 patients with liver cirrhosis. There was no significant difference of the amount of shunt index reduction after propranolol according to Childs' classification and the degree of esophgageal varix. Conclusion : The effect of propranolol on portal circulation was demonstrated as decreasing shunt index on per-rectal portal scintigraphy in patients with liver cirrhosis. Per-rectal portal scintigraphy may be useful to evaluate the portal circulation and to predict the effect of propranolol in patients with liver cirrhosis.

Regular exercise is effective in preventing coronary disease such as angina pectoris and infarction, inside it can lower the blood pressure and aids in weight control and release of stress. Risk factors of arteriosclerosis is hypertension, hyperlipidemia, diabetes, obesity, physical inactivity and excessive smoking. Arteriosclerosis begins at young age worsens with age, particulary in male. For people with risk factors of arteriosclerosis, it is important to prevent arteriosclerosis-related disease with dietary, living pattern and exercise prescription. Dietary fibers promote exercise of the digestive tract and shortens the time food remains inside the digestive tract. It can prevent obesity, hyperlipidemia, arteriosclerosis and colin cancer by blocking the absorption of cholesterol. Various vegetables and sea foods are lichen unsaturated fats and prevent the absorption of cholesterol inside the digestive tract. Essential fatty acids and unsaturated fats which are contained in vegetable oils, promotes metabolism while preventing absorption. In fruits, pectin water-soluble fiber, is present and lowers the level of cholesterol. By consuming foods that low in cholesterol and saturated fats, and rich in unsaturated fats, aliomentotherapy alone can reduce the plasma cholesterol by 10~l5$\%$. For ideal exercise, it should be aerobic with intensity of 60~80$\%$ HRmax, duration of 15~60min/day. The frequancy of 3~6/week is desirable the better exercise prescription is endurance aerobic exercise. To get more effect exercise, exercise consistency is very important.

Lentinus giganteus, one of edible and medicinal mushroom belongs to Pleurotaceae of Agaricales, has been known to contain some inhibitive substances on Sarcoma 180 and curative effect on high blood pressure. Neutral saline soluble (0.9% NaCl), hot water soluble and methanol soluble substances (hereinafter referred to Fr. NaCl, Fr. HW and Fr. MeOH, respectively) were extracted from fruiting body of the mushroom. In vitro cytotoxicity tests, crude polysaccharides were not cytotoxic against cancer cell lines such as Sarcoma 180 and HepG2 at the concentration of $10{\sim}2,000\;{\mu}g/ml$, but crude polysaccharides from Fr. NaCl was toxic to NIH3T3 at the concentration of $10{\sim}2,000\;{\mu}g/ml$. Intraperitoneal injection with crude polysaccharides showed life prolongation effect of $14.3{\sim}67.5%$ in mice previously inoculated with Sarcoma 180, respectively. Fr. NaCl exhibited the immuno-potentiating activity of B lymphocyte by increasing the alkaline phosphatase activity by $1.53{\sim}1.68$ folds compared with control at the concentration of $50{\sim}200\;{\mu}g/ml$, respectively. The numbers of peritoneal exudate cells and circulating leukocytes were increased by 7.7 and 1.6 folds by injecting Fr. NaCl and Fr. MeOH into the mice at the concentration of 50 mg/ml body weight, respectively.

The hemodynamic changes in septic patients produced by inhalational anesthetics are sufficient to threaten the anesthesiologists. The effect of hydroxocobalamin, a vitamin $B_{12a}$, on contractile responses to phenylephrine during administration of inhalational anesthetics were evaluated in aortic ring preparations obtained from LPS-treated rats. The sepsis was developed by intraperitoneal injection of LPS (1.5 mg/kg for l8h) and confirmed by iNOS expression using RT-PCR. Statistical significances (P<0.05) were analyzed by Student's t-test or paired t-test according to data characteristics. The blood pressure, but not heart rate, was decreased in LPS-treated rats as compared to control rats. The contractile response to phenylephrine were dose-dependently increased from the doses of $10^{-8}\;M$ to that of $10^{-5}$ and were attenuated in LPS-treated rings. Both halothane and enflurane, at the doses of 1 MAC, decreased the contractile responses to phenylephrine while isoflurane did not significantly affect the contractile responses. Hydroxocobalamin ($10^{-5}$ M) significantly potentiated the contractile responses in the LPS-treated aortic ring preparations during administration of each inhalational anesthetic or not. From these results, it is suggested that hydroxocobalamin may improve the hemodynamics of septic patients during inhalational anesthesia.
