  • Perspiration is the product of metabolism and the resin comes out through the hole of skin. And it keeps constant with heart and blood. So, it has great meaning in the clinical medicine and it is closely connected with the qi, blood, body fluid and viscera in our body. In the oriental medicine it is said that when our body is attacked with the evil qi and it locates in the surface of our body, we must induce the perspiration and it is called 'Method of Perspiration'. If we use that method we should refer the contraindication, and historical doctors stressed the need of deliberate use. However, the moderns have the misunderstandings about the perspiration. When they have alcoholic trouble and feel fatigue, they wring out the sweat. And they think that doing has good results. They even sweat off their surplus fat. But, that doing is rashly as that is an energy-consuming behavior and it shorten one's span of life because of the running dry of the resin. Therefore, we must use very carefully the 'Method of Perspiration' and not wring out the sweat rashly.

  • Doing CABG in patient with renal transplantation requires special concern to keep and preserve renal function safely during and after operation. We experienced two cases of CABG for treatment of myocardial ischemia. who underwent renal transplantation 2 and 3 years ago respectively. The first patient received single reversed saphenous vein graft at LAD and second one received double saphenous vein graft at LAD and OMI. Peri & postoperative urinary volume and renal function test were comparable with preoperative status in both cases. Although abnormal lipid metabolism due to long term use of immunosuppressive regimen act a causative role in development and progression of coronary artherosclerosis in renal transplantation patient, CABG can be done safely with some precaution including maintenance of adequate mean blood pressure and blood level of immunosupressive regimen during cardiopulmonary bypass.

  • In order to evaluate the mode of action of ginseng saponin. metabolic changes in the plasma of normal and aloxan-intoxicated rats were compared Normal groups were administered only ginseng saponin 0, 5, 50mg/kg for 16 days, but alloxan-intoxicated groups were administered alloxan 25mg/kg for 3 days in addition to ginseng saponin. (1) No significant change in the concentration of glucose, cholesterol, and triglyceride (TG) was observed in normal rats but great inhibitory effect, except elevation of TG, was observed in alloxan-intoxicated rats. However, blood urea nitrogen was elevated in both normal and alloxan- intoxicated rats by administration of ginseng saponin 50mg/kg, and it was considered to be due to the impaired kidney function caused by overdose toxicity. (2) In normal rats, COT and ALP actIn,its were not changed by administration of ginseng saponin but GPT activity was decreased significantly. In alloxan-intoxicated rats, ginseng saponin exerted inhibitory action on the elevation of COT, CPT and ALP activity. But administration of ginseng saponin Smghg was much more effective than administration of 50mg/kg. (3) There fore, we concluded that ginseng saponin has the adaptogenic activity showing little effect on normal metabolism but great preventive action on alloxan-intoxicated rats.

  • TR8 is a recently identified member of the tumor necrosis factor (TNF) receptor superfamily. TR8 seems to play important roles in bone metabolism as stimulation of this receptor with its ligand, TL8 or osteoclast differentiation factor (ODF), induced the differentiation and activation of osteoclasts. Despite its important biological functions, the biochemcial events ensuing form TR8 activation have not been revealed in detail. Most of TNF receptor family proteins provoke the activation of the NF-$textsc{k}$B transcription factor. In the present study, we examined the signaling potential of TR8 to induce NF-B activation. When overexpressed in a human embryonic kidney cell line by transient transfection, TR8 caused a strong activation of NF-$textsc{k}$B, which was further increased upon stimulation with TL8. The TR8-induced NF-B activation was abrogated by the co-expression of the TRAF6 mutnat lacking the Ring and zinc finger domains and that of the kinase-inactive mutant NIK. Taken together, our study suggests that the presence of intact TRAF6 and the kiase activity of NIK may be essential for TR8 to induce NF-$textsc{k}$B activation.

  • Recently lots of books on the process of growing have been published on adolescence and their parents hope to grow tall but yet lacked the correct knowledge. Before helping the growth of body, the best way is to do away with the check factors of the human body. Therefore oriental and occidental medicine study on the inhibition of growth and the result of case study about life therapy, kinesiatrics, including medical therapy are as follows: The habits that help the process of growing are deep sleep, balanced diets, daily physical exercise, good posture. It is essential for people to relieve stress. The physical exercises that promote the process of growing are as follows: to stretch out, daily suitable exercise which stimulates the metabolism of human body to increase levels of growth hormone and excite growth plate, to hasten the process of growing, Oriental medicine causes on the inhibition of growth show many factors: kidney trouble is the inhibited cause, spleen ailment is the acquired ground. The lack of essence of the dual principal of the negative and the positive makes people the inhibition of growth. All these things including fire and dryness have close relations.

  • The metabolic transit of three samples( 14C glycine-glyucose melanoidin, glycine-glucose melanoidin and soybean sauce ) were studied on rats. The radioactivity of various organs and excreta intubated 14C glycine-glucose melanoidin on rats at various intervals(1, 3, 8, 12, 24, 48, 72 and 96 hrs were detected . And the brown pigment contents and hydrogen donating activities in the excreta which is obtained from three samples were detected during the 7 days after intubated. The total amount of 14C excreted in the fecese were 53% meaning that the rest of 47% melanoidin seemed to be retained in the body or metabolized . The radioactive compound showed a small retention in the liver and kidney. The brown pigment contents and hydrogen donating activities in the urine and feces increased proportionally to the activity of 14C. When the soybean sauce and glycine glucose melanoidin were intubated, the brown pigment contents excreted in the feces were found to be the highest after 1 st day of intubation. In the urine, the model melanoidin was excreted mostly after 3 days of intubation. The brown pigment contents and hydrogen donating activities of three samples of excreta agreed with each other. The soybean sauce retained longer than model melanoidin in the body is telling that it might have antioxidative activity in vivo.

  • The changes in pharmacokinetic parameters of tolbutamide, such as the area under the plasma concentration-time curve from time zero to time infinity (AUC) and elimination rate constant (Kel) were evaluated after oral administration of the drug to rabbits with acute and chronic alloxan-induced diabetes mellitus (AIDRs). After oral administration, the plasma concentrations of tolbutamide were significantly higher between 9 and 12 hr in chronic AIDRs compared with these in control rabbits. Therefore, the AUC was significantly greater in chronic AIDRs $(3,490{\pm}649\;versus\;5,020{\pm}1,030{\mu}gml{\cdot}hr)$. This could be due to inhibition of tolbutamide metabolism by liver in AIDRs since tolbutamide is essentially completely metabolized in liver. Impaired liver and kidney function in AIDRs were based on blood chemistry and tissue microscopy. The absorption rate constant and Kel were significantly slower in chronic AIDRs compared with those in control rabbits.

  • This study was performed to investigate the effect of chlorella on cadmium (Cd) toxicity in Cd-administered rats. Sixty male Sprague-Dawley rats (14 week-old) were blocked into 6 groups. Cadmium chloride was given at levels of 0 or 325 mg (Cd: 0, 160 ppm), and chlorella powder at levels of 0, 3 and 5%. Cadmium was accumulated in blood and tissues (liver, kidney and small intestine) in the Cd-exposed groups, while the accumulation of Cd was decreased in the Cd-exposed chlorella groups. Fecal and urinary Cd excretions were remarkably increased in Cd-exposed chlorella groups. Thus, cadmium retention ratio and absorption rate were decreased in the Cd exposed chlorella groups. Urinary and serum creatinine, and creatinine clearance were not changed in experimental animals. In addition, metallothionein (MT) synthesis in tissues was increased by Cd administration. The Cd-exposed chlorella groups indicated lower MT concentration compared to the Cd-exposed groups. Moreover, glomerular filtration rate (GFR) was not changed by dietary chI orella and Cd administration. According to the results above, this study could suggest that Cd toxicity can be alleviated by increasing Cd excretion through feces. Therefore, when exposed to Cd, chlorella is an appropriate source which counteracts heavy metal poisoning, to decrease the damage of tissues by decreasing cadmium absorption.

  • Purpose: This study is to examine anti-obesity effect and cytotoxicity of the long-term oral administration of Ephedra Sinica(Ma-hwang, ES) Methods: Using diet-induced obesity C57BL/6 mouse model, anti-obesity effect and DNA chip expression and cytotoxicity of the long-term oral administration of this herbal extract were investigated. Results: The herbal extract treated groups were arrested in weight increment only when they were lodged together. Such effects were abolished when they kept individually. ES fed mice behaved very rudely and violently. On the basis of histological studies of liver tissues and also in vitro cytotoxicity tests of the liver and kidney cell lines, no significant toxicity was found by 14 weeks of ES treatments. However, we found significant changes in gene expression profile in ES treated group by micro-array analysis. In case of ES group, up-regulated genes were 113 and down-regulated were 120. Some of lipid metabolism related genes also significantly changed in treatment groups. Conclusion: ES had effects of increasing the basal metabolic rate by stimulating the sympathetic nervous systems.

  • Objectives: Bee venom (BV) therapy is performed by a bee sting or subcutaneous injection of BV. However, there is not much information on the effect of BV on blood parameters after entering the body. This project aimed to assess the side effects of subcutaneous BV injections in healthy rats by measuring the hematological and biochemical parameters. Methods: Various amounts of BV, including 100, 200, and 500 (㎍/day), were subcutaneously injected into rats for 30 days. The results showed that BV affected the metabolism of the liver, kidney, and glands. Results: An increase in blood sugar and a decrease in other biochemical parameters, including cholesterol, triglyceride, urea, creatinine AST, ALT, ALP, and phosphorous, were observed. Results also showed increased counts of white blood cells, neutrophils (%), and platelets and decreased levels of red cells, hemoglobin, and hematocrit. Conclusion: This study demonstrates that BV therapy in medical clinics requires routine care and testing to prevent eventual metabolic and anemia side effects.
