  • In order to testify the urate lowering effects of Daihwangmudan-tang(DMT), ICR mice were injected monosodium urate into the abdominal cavity and then DMT was administered on 2 and 4 days after Injection. Uric acid and triglyceride were measured as hematological indices of gout, and some genes related with this change were identified by ACP based GeneFishing PCR method and direct sequencing. From this experiment, DMT highly decreased the blood levels of uric acid and significantly suppressed and lowered the acute increment of triglyceride level. There were 11 differentially expressed genes(DEG) having relations with positive actions of DMT, and 4 major genes in the middle of DEGs were sequenced; Mfap 2, jagged 2, Hsd17b7, DkkI-1, These genes were supposed that several mechanisms through interleukin 1 and T-cell anergy, LDL cholesterol metabolism, wnt pathway would be related with the anti-inflammation effect against gout.

  • The spleen is the source of gi, blood, body fluid and plays a vital role in maintaining life. The function of the spleen is to transform food nutrients and water, and to transport them to the heart and the lung. The movement of splenic gi is marked by elevation. The spleen governs the activity of elevating the lucid. The function of transportation and transformation is usually disturbed in the state of Gi deficiency of the spleen. The main clinical manifestations of gi deficiency of the spleen can be divided into as followers: anorexia, loose stool if the digesting and absorbing functions are disturbed; phlegm and edema if dampness and water are retained due to unhealthy water metabolism. Sagunja-tang can be applied for gi deficiency syndrome of the spleen. Ingredient bakchul(Rhizoma Atractylodis Macrocephalae) and bokryeung(Poria) can be used as monarch drug to eliminate dampness and strengthen the spleen.

  • This study was done to investigate the effect of SHCG on hypertension in spontaneous hypertensive rats. SHR was sensitized and challenged with Sihogayonggolmoryeotanghabcheongsimyeonjaemgagambang (SHCG) for 4 weeks. The 3 groups have 6 rats, respectively. Experimental group was treated with 56.7 mg/kg of SHCG orally and control group was treated with 56.7 mg/kg of normal saline instead. SHCG significantly showed safety against cytotoxicity on hFCs and toxicity in the liver. SHCG significantly decreased the blood pressure and the heart rate. SHCG significantly decreased the levels of aldosterone. SHCG significantly decreased the levels of dopamine, norepinephrine, and epinephrine. SHCG significantly decreased the levels of potassium and chloride. SHCG significantly decreased the levels of uric acid and creatinine. These results suggest that SHCG might be hopeful in treatment of hypertension.

  • Kamicheonmagudeungeum(KCGE), a traditional herbal medicine, has been used as a therapeutic agent for the treatments of acute stage of hypertension. We evaluated the effects of KCGE on hypertension induced by DOCA-salt in rats. The systolic blood pressure and pulse rate significantly lowered by oral administration with KCGE. The levels of plasma hormones including dopamine, epinephrine and norepinephrine, and serum electrolyte were also reduced in KCGE treated rats. In addition, the production of reactive oxigen species (ROS) were greatly decreased by the treatment with KCGE in cultured bovine endothelial cells and angiotensine converting enzyme (ACE) activites were also inhibited by KCGE in a dose dependent manner. This study indicated that KCGE is a safe and effective treatment for hypertension.

  • Drug delivery to the brain is facilitated by the synthesis of chimeric peptides, where in neuropharmaceuticals are linked to a vector such as an antibody to the transferrin receptor that mediates transcytosis through the blood-brain barrier (BBB). When disulfide linkers are used in the chimeric peptide, it is crucial that the S-S bridge is stable during transit and that cleavage does not occur prematurely within endothelial cells, as the peptide drug moiety would then be sequestered by the BBB instead of passing through it. The present study addressed that problem. As a model drug a metabolically stable opioid peptide, [$^3$H]DALDA (Tyr-dArg-Phe-Lys-NH$_2$), was used. It was monobiotinylated with NHS-SS-biotin to yield bio-[$^3$H]DALDA. The biotinylated peptide was bound to the vector OX26-SA which is a covalent conjugate of OX26 and streptavidin (molar ratio = 1: 1). In vitro treatment of the chimeric peptide, bio-[$^3$H]DALDA/OX26-SA, with a reducing agent, dithiothreitol, released the labeled peptide from the vector by conversion of bio-[$^3$H]DALDA to the desbiotinylated derivative, desbio-[$^3$H]DALDA.

  • Ginsenosides are among the most well-known traditional herbal medicines frequently used for the treatment of cardiovascular symptoms in South Korea. The anti-ischemic effects of compound K (CK), a metabolite of ginsenoside Rb1, on ischemia-induced isolated rat hearts were investigated through the analyses of the changes in the hemodynamics (blood pressure, aortic flow, coronary flow, and cardiac output) and the measurement of the infarct region. The subjects in this study were divided into four groups: the normal control, the CK-alone group, the ischemia-induced group without any treatment, and the ischemia-induced group treated with CK. No significant differences in perfusion pressure, aortic flow, coronary flow, and cardiac output were found between the groups before ischemia was induced. The oxygen and buffer supply was stopped for 30 min to induce ischemia 60 min after reperfusion in the isolated rat hearts, and the CK was administered 5 min before ischemia induction. The CK treatment significantly prevented decreases in perfusion pressure, aortic flow, coronary flow, and cardiac output under ischemic conditions. In addition, the hemodynamics (except for the heart rate) of the group treated with CK significantly recovered 60 min after reperfusion, unlike in the control group. CK significantly limited the infarct. These results suggest that CK treatment has distinct anti-ischemic effects in an exvivo model of an ischemia-reperfusion-induced rat heart.

  • The purpose of this study was to develop a system dynamics model for management of glucose metabolism disorders that demonstrated dynamic relationships between insulin and plasma glucose levels over the time. The model was developed to 1) represent the physiology of glucose metabolism for an normal adult subject, 2) to draw causal loop diagram that demonstrate feedback systems of glucose regulation in normal condition and pathologic condition of the type 2 diabetes, 3) to develop an interactive computer simulation model for management of glucose metabolism disorders. The simulation results showed the plasma glucose level for normal persons varied from 75 to 140 which was consistent with clinical findings. As an example for patients we selected a case which varied from 110 to 310. Two types of interventions were chosen to review the model; meal control and insulin administration. The simulation results for those cases also matched well with clinical findings. The developed model can be used as an effective educational tool for patients to develop healthy lifestyle choices. The results also provide a blueprint for health providers to maintain normal blood glucose levels in diabetes patients.

  • Cyclic nucleotide phosphodiesterases (PDEs) represent the unique enzymatic system degrddinf cAMP and cGMP which play a major role in the regulation of cell physiology. To investigate a possible molecular mechanism of ginsenosides, their activities were evaluated on PDEs which are recently described is new therapeutic targets. PDEs are classified into 7 families according to their genes (PDEI to PDE7) and are differently distributed in tissues. The IC50 values of ginsenosides were determined on PDEI to PDE 5 chromatographically isolatetl from bovine aorta. The results show that total ginseng saponin extract preferentially inhibits PDE 1 and PDE4 at concentrations nearby 200 ug/ml. Protopanaxadiol (PPD) fraction acts preferentially on PDE4 with and IC50 value of 100 nlml and inhibits also PDEI and PDE5 at 14 to 2 fold higher concentrations, respectively. Protopanaxatriol (PPT) fraction preferentially inhibits PDE 1 with and IC50 value of 170 ug/ml. Compound Rgl, originated from PPT fraction, and RC3 (5) represent the most active compounds towards PDE 1 with IC50 values around 80 UM. However Rg3 (R), epimer of Rgl (5) has no effect on the various PDEs tested, excepted on PDE3 rich is sligthly sensitive Compound Rbl, originated from PPD, acts on both PDEI and PDE4. It if two fold less active than Rgl and Rg3 (5) on PDEI. Taken together, these results mainly suggest that PDEI and PDE4 inhibitions could be a molecular mechanism which would participate in ginsenoside mechanisms, especially the effect of PPD on blood vessel and on CNS.

  • Purpose The purpose of this study was to investigate sub-chronic toxicity of scolopendrid pharmacopuncture in mouse and method of increasing output of scolopendrid pharmacopuncture. Methods In order to prove the clinical safety of scolopendrid pharmacopuncture during 90 days, We have observed the physical reaction(side effect) and clinical pathology test after scolopendrid pharmacopuncture treatment and investigated method of increasing Output of scolopendrid pharmacopuncture for 90%, 80%, 70% ethanol. Results In subchronic toxicity test, there was no significant sign in clinical sign, opthalmological values, body weights, hematological values and urinalysis values. And we could see that food consumptions and water consumptions increased significantly, albumin, triglycerides, GPT in blood chemical values and Liver, Testis(right) in organ weights changed significantly in some groups, compared with those in the S1 group. But these changes were observed within the scope of physiology. So there was no sign of toxication in subchronic toxicity test, and we can tell that NOAEL(No Observed Adverse Effect Level) is above 0.286mg/kg/day. And 70% ethanol solution of scolopendrid was yielded the most amount of substance. Conclusions This study demonstrates that scolopendrid pharmacopuncture is to treatment of safety for a long time and we can obtain much amount from 70% ethanol solution of scolopendrid.

  • In this study, we structuralized the diagnostic indices used for pattern identification (PI) of stroke, and suggested an AHP method to obtain the weights of PI indices. AHP of the subjects under consistency ratio 0.1 showed that the critical indices for stroke PI consists of 9 for Qi-deficiency, 13 for Phlegm/dampness, 7 for blood stagnation, 12 for Yin-deficiency and 16 for Fire/heat. Furthermore, AHP analysis rendered the weights of indices of each PI that will be useful for oriental medical experts to perform objective PI.
