On the basis of the widely collected fork prescriptions, long clinical practice of himself, together with integration of all the good points of earlier medical specialists, 孫思邈 wrote 『千金方』 of thirty volumes. Among them Volumes 『食治』 (Food Therapy) and 『養性』(Cultivating the Character) are especially meaningful for in gerontology. Thirty years after its completion, as a supplement, he wrote another thirty volumes of 『千金翼方』. Mr. Sun integrated his discoveries in the treatments of the aged patients, and his opinions for longevity into the Volumes 『養性』 (Cultivating the Character), 『?穀』(Fasting), 『退居』(Retirement), 『補益』(Supplementation). Thus he laid down the basic foundation for the gerontology of Chinese medicine. 『千金要方』 and 『千金翼方』 by Mr. Sun discuss mainly the prevention of illness for aged patients. As for the function of food therapy, he explains: 'Food can dispel evil elements of the body and settle down its organs. It can further bring pleasure to man's spirit and help the circulation of blood and breath.' He then propose the major method of food therapy: 'For a medical doctor, he should understand the causes of disease, then treat it with food. Only after the food treatment fails, medicine is employed.' He thinks that medicine does work in treatment, but it also creates imbalance in the body, and makes the latter vulnerable to outside harms. Therefore, a good doctor is the one who cures the disease and bring pleasure to the patient with food. He stresses that food therapy is always a priority. Mr. Sun prefers animal's organs in the food therapy for aged. For example, he uses powder of sheep's kidney to treat the lumbago. He suggests the viewpoint of 'Curing man's organs with animal's organs' and 'Strengthening man's organs with animal's organs,' and sets the theoretical foundation of 'Organic Treatment.' Mr. Sun's gerontology and food therapy received further development latter. The prescriptions contained therein had been widely used in 王懷隱's 『太平聖惠方』 and 陳直's 『養老奉親書』, both in the Song Dynasty. Eventually they had become a science of food therapy for aged patients.

We report one case of an 18-day-old female patient, weighing 3.4 kg, with severe cyanosis. The diagnosis was made with only transthoracic echocardiography, which revealed cor triatriatum with an atretic small opening of fibromuscular membrane, obstructive infracardiac total anomalous pulmonary venous drainage(TAPVD), severely restrictive interatrial communication, and scanty mitral inflow and aortic forward flow. The preoperative decision-making for biventricular repair was not easy due to collapsed left heart system caused by remarkably reduced blood flow An emergent operation was performed due to severe cyanosis. All left heart structures were somewhat hypoplastic but thought to be adequate for systemic circulation. Biventricular repair was done without specific intraoperative problems. The postoperative course was uneventful. The patient has been doing well with no evidence of pulmonary vein stenosis or mitral regurgitation for 4 months after operation.

INTRODUCTION: Local heat and cold application has been frequently used as means of muscle relaxation and blood circulation or reinforcing muscle strength, relaxing muscle tension in clinical situation. In particular, it has been known that long-term heat and cold application for relaxing muscle tension inhibits muscle spasticity or tension. But, it has been rarely reported that what influences of heat and cold application on activation of muscle action potential. Therefore, this study aims to analyze surface temperature and electromyography activities according to the heat and cold application. METHODE: Subjects of this research were 10 normal men and women (5 men, 5 women). Hot pack and cold pack was applied to vastus medialis muscle of thigh and rectus femoris muscle for 20 min. Surface temperature of vastus medialis muscle and rectus femoris muscle was measured, knee joint of subjects was in $45^{\circ}$ flexion, sitting on a chair, maximal isometric contraction was induced, surface electromyography (sEMG) signals were collected and root mean square (RMS) and median frequency (MOF) were analyzed. All measurements were conducted before and immediately after experiment, 10 min., 20 min. and 30 min. after experiment. Data were analyzed with SPSS 12.0 program, comparison of changes in superficial temperature and sEMG signals through repeated measurement was conducted with repeated measures ANOVA and significance level $\alpha$ was 0.05. RESULTS: Changes of surface temperature of vastus medialis muscle according to cold application were radically decreased immediately after application, but it was recovered after 30 min. of application and it showed significant difference (F4. 36=72.216, P<0.001). Surface temperature of rectus femoris also showed radical decrease immediately after application, but it was recovered after 30 min. of application and showed significant difference (F4. 36=88.930, P<0.001). Changes of surface temperature of vastus medialis muscle according to heat application were radically increased immediately after application, but it was recovered after 30 min. of application and it showed significant difference (F4. 36=27.267, P<0.001). Surface temperature of rectus femoris also showed radical decrease immediately after application, but it was recovered after 30 min. of application and showed significant difference (F4. 36=19.774, P<0.001). Changes of sEMG by heat and cold application were no statistical difference. Surface temperature of skeletal muscle after heat and cold application showed significant change for 30 min., but it was found that increase or decrease of surface temperature had not great influence on sEMG activities.

Biological activities of enzymatic hydrolysate of spirulina (EHS) were investigated. EHS showed no significant effects on the growth-stimulating activity for lactic-acid bacteria and antioxidant activity. EHS showed slight in vitro growth-inhibitory effects (15% at 1.42 mg/L) on a human cervical cancer cell line (HeLa). In addition, the anticoagulant activities of EHS were measured based on three different pathways: common, intrinsic and extrinsic pathways. As an indication of anticoagulant activity on common pathway, thrombin time (TT) of EHS (100 mg/L) was measured as 155.6 sec. Activated partial thromboplastin time (aPTT) for intrinsic pathway of EHS (1,000 mg/L) was measured as 95.8 sec. Prothrombin time (PT) based on extrinsic pathway of EHS (1,000 mg/L) was measured as 10.6 sec. These data showed that EHS have influences on anticoagulant factors of common pathway and intrinsic pathway. Consequently it was found that EHS could be used as a functional food for blood circulation.

The purpose of the present study was to examine the pharmacokinetic characteristics of arsenic hexaoxide($As_4O_6$), a novel anticancer compound, after i.v. bolus and oral administration in rats. We developed an ICP-Mass based method to analyze arsenic hexaoxide levels in plasma, bile, urine, feces, and tissue and validated the method. Arsenic hexaoxide rapidly disappeared from the plasma by 10 min($\alpha$ phase) after i.v. administration, which was followed by the late disappearance in the $\beta$ phase. The mean plasma half-lives($t_{1/2}$) of arsenic hexaoxide at the a and $\beta$ phase when administered at a dose of 5 mg/kg were 1.57 and 29.8 min, respectively. The maximum plasma concentration($C_{max}$) was 230 ng/mL, after oral administration of arsenic hexaoxide at a dose of 50 mg/kg. The bioavailability, which was calculated from the dose-adjusted ratio, of the oral administered arsenic hexaoxide was 1.61%. Of the various tissues tested, arsenic hexaoxide was mainly distributed in the spleen, lung, liver and kidney after oral administration. Arsenic hexaoxide levels in the spleen or lung at 24 hr after oral administration were higher than those of maximum plasma concentration($C_{max}$). The cumulative amounts of arsenic hexaoxide found in the urine by 48 hr after the administration of 50 mg/kg were 5-fold higher than those in the bile. However, the cumulative amounts in the feces were 10-fold higher compared with those of urine, suggesting that arsenic hexaoxide is mostly excreted in the feces. In conclusion, our observations indicated that arsenic hexaoxide was poorly absorbed from the gastro-intestinal tract to the blood circulation and transferred to tissues such as the spleen and lung at 24 hr after oral administration. Moreover, the majority of arsenic hexaoxide appears to be excreted in the feces by 48 hr after oral administration.

Alterations in splanchnic circulatory hemodynamics along with reactivities to the alpha adrenoceptor agonists were assessed in association with the preventive effects of propranolol 10 days after portal ligation. Decreases in precapillary resistance (Ra) and postcapillary resistance (Rv) along with increases in mesenteric blood flow (MBF) and capillary pressure (CP) were observed in conjunction with an increment of splenic pulp pressure (SPP). Dose-dependent increase in Rv in response to noradrenaline, increases in Ra and RV to adrenaline, and increases in superior mesenteric arterial pressure (SMAP), Ra and Rv to phenylephrine observed in sham group were significantly attenuated by portal vein stenosis. In PPL-3 group (propranolol 3 mg/kg, i.p. three times daily for 10 days), MBF was significantly decreased in association with decrease in mesenteric venous pressure (MVP) when compared with those of protal ligated (PL) group, and decreased Ra and Rv in PL group were recovered toward the values of sham group. Likewise, in PPL-1 group (propranolol 5 mg/kg, i.p. once daily for 10 days), the pressor response of Rv to adrenaline was recovered up to the level of sham group. Thus, it is suggested that decreases in Ra and Rv in association with increases in MBF and CP may have a close relevance to the increased SPP, and the changes in circulatory hemodynamics and vascular reactivities were effectively reversed by longterm propranolol treatment. Based on these results, it is concluded that these changes observed in portal hypertension are closely related with the altered functions of the adrenoceptors in the splanchnic vascular beds.

A previous study reported that Ulmus macrocarpa Hance water extract (UME) can improve hyperlipid metabolism and the involvement of suppressed lipid synthesis through adenosine monophosphate-activated protein kinase (AMPK) pathway regulation was suggested. Further exploration of the lipid metabolism between liver and peripheral tissue was necessary to confirm that work, and so this study aimed to extend the possibility that UME can regulate serum lipids. After a 6-week in vivo trial of oral administration of UME to rats with induced hyperlipidemia, serum levels of triglyceride (TG) and total cholesterol (TC) were seen to decrease while HDL cholesterol increased. The UME administrations also decreased the TC and TG levels from the control in liver analysis. However, the suggestion that UME regulates the AMPK pathway to improve hyperlipid states through the suppression of hepatic lipogenesis seems to be only one part of the extract's effect. Indeed, serum concentrations of apolipoproteins A and B were returned to baseline levels of the control group in response to UME administration whilst the liver lipid content was much reduced; this cannot occur through the suggested suppression of hepatic lipogenesis alone. Therefore, a possible mechanism of UME could be that it improves blood circulation by modulating serum lipid levels through both the prior stimulation of lipid oxidation and the suppression of hepatic lipogenesis.

A solid-state culture based on grain materials was attempted to produce a fibrinolytic enzyme for blood circulation improvement using Bacillus subtilis BK-17. The spore, rather than vegetative cell inoculation, of B. subtilis BK-17 on the solid-state culture was effective in the production of a fibrinolytic enzyme. Maximum spore production was obtained with a SFM medium (0.8% nutrient broth, 0.05% yeast extract, $10^{-1}$ M $MgCl_2$, $10^{-3}$ M $FeCl_3$, $10^{-4}$ $MnCl_2$, $10^{-5}$ M dipicolic acid, pH 6.5). Optimal pH and temperature were pH 6 and $30^{\circ}C$, respectively. The spore production reached a maximum at 60 hours of incubation. Bacillus subtilis BK-17 on the mung bean solid-state culture produced greater fibrinolytic activity, and less activity was seen in other grains such as kidney bean, soybean and corn. Protein and lipid contents of fermented soybeans were about 10 - 30% more than those of unfermented soybeans. Amino acid content was also 5 - 20% more than that of unfermented soybeans. These results indicated that fermented solid-state culture medium, fermented soybean in this case, can be utilized as a food supplement.

Korean Red Ginseng (RG) are used as a traditional treatment for improve blood circulation. This experimental study was designed to investigate the inhibitory effects of Korean red ginseng on lipid metabolism in high fat/cholesterol diet (HFCD)-induced hypertriglyceridemia. Sprague Dawley rats were fed the HFCD diet with/without fluvastatin (Flu, positive control) 3 mg/kg/day, and RG 125 or 250 mg/kg/day, respectively. All groups received regular diet or HFCD diet, respectively, for 13 weeks. The last three groups treatment of Flu and RG 125, and RG 250 orally for a period of 9 weeks. Group 1, reular diet; group 2, HFCD diet; group 3, Flu + HFCD diet; group 4, RG 125 + HFCD diet; group 5, RG 250 + HFCD diet. As a result, treatment with low or high doses of RG markedly attenuated plasma levels of triglycerides and augmented plasma levels of high-density lipoprotein (HDL) in HFCD-fed rats. RG and Flu also led to an increase in lipoprotein lipase activity in the HFCD group. On the other hand, RG and Flu led to an decrease in fatty acid synthase and free fatty acid activity in the HFCD group. Treatment with RG suppressed increased expressions of $PPAR-{\alpha}$ and AMPK in HFCD rat liver or muscle. In addition, the RG attenuated triglyceridemia by inhibition of $PPAR-{\gamma}$ and FABP protein expression levels and LXR and SREBP-1 gene expression in liver or muscle. The RG significantly prevented the development of the metabolic disturbances such as hypertriglyceridemia and hyperlipidemia. Taken together, the administration of RG improves hypertriglyceridemia through the alteration in suppression of triglyceride synthesis and accentuated of triglyceride decomposition. These results suggested that RG is useful in the prevention or treatment of hypertriglyceridemia.
