  • To investigate the effects of coated liposome from Discorea rhizoma extract (DRE) in streptozotocin (STZ)-induced, we evaluated changes in body weight, fasting blood glucose, blood insulin and blood lipid concentrations in mice. Mice were divided into four groups: (DC), diabetic DRE at 10 mg/kg (DRE-1), diabetic DRE at 50 mg/kg (DRE-2), and diabetic DRE at 250 mg/kg (DRE-3). Mice had free access to water and diet (10 weeks). The DC group showed higher blood cholesterol than the DRE-1, DRE-2, DRE-3 groups. In glucose tolerance test, the DRE-1, DRE-2, and DRE-3 groups increased after 30 minutes in decremental glycemic response area under the curve. Fasting blood glucose levels in the DRE groups significantly decreased through 4 weeks. Plasma total cholesterol, triglyceride and LDL-cholesterol concentrations were also lower in the DRE groups. On the other hand, the DRE-1, DRE-2 and DRE-3 groups showed higher HDL-cholesterol and insulin levels than the DC group. Moreover, blood glucose and lipid levels significantly decreased in streptozotocin (STZ)-induced diabetic mice treated with DRE. These results indicate that DRE may reduce elevated blood glucose levels and serum lipid concentrations in hypoglycemic and diabetic mice, suggesting its usefulness as a functional food.

  • A 1 : 1 mixture of acriflavine (ACF; CAS 8063-24-9) and guanosine is currently being evaluated as a possible antitumor agent in preclinical studies. Guanosine is known to potentiate the anticancer activity of some compounds. However, the distributions of trypaflavine (TRF) or proflavine (PRF) have not been investigated in mammals. We, therefore, investigated the distribution of TRF and PRF after i.m. administration of the combination mixture (ACF and guanosine) at a dose of 30 mg/kg ACF in rats. to analyze TRF and PRF levels in biological samples, we used an HPLC-based method. The calibration curves for TRF and PRF in the samples were linear over the concenration range of $0.05{\sim}200\;{\mu}g/ml$. The intra- and inter-day assay accuracies of this method were within ${\pm}15\%$ of norminal values and the precision did not exceed $15\%$ of relative standard diviation. The lower limits of quantitation were 50 ng/ml for both TRF and PRF. The distribution of TRF or PRF was determined by 48 h after i.m. administration of the combination mixture at a dose of 30 mg/kg ACF. TRF and PRF were distributed as the following order; kidney>lung>liver>small intestine>muscle. Of the various tissues, TRF and PRF were mainly distributed to the kidney and lung. The concentrations of TRF or PRF in the tissues 24 h after i.m. administration decreased to undetectable levels. The concentrations of TRF or PRF in the blood cells were comparable to those for the plasma. However, the concentrations of TRF or PRF in the both plasma and blood cells 12 h after i.m. administration were not detected. The number of the platelets in the 1 ml of the blood was calculated to be $0.183{\times}10^8/ml$ of blood. The PRF concentration in platelets was higher than that of TRF at initial times after i.m. administration of the combination mixture. However, both the TRF and PRF concentrations in the plateles 24 h after i.m. administration of the combination mixture were below the quantifiable limit. In conclusion, the concentrations of TRF or PRF in the various tissues, plasma, blood cells, and plateles decreased to undetectable levels 24 h after i.m. administration of the combination mixture at a dose of 30 mg/kg ACF.

  • In order to investigate experimentally the effects of Sung-yangikgibujat'ang (SIT) and Kwangyebujalijungt'ang (KBT) on Yang-insufficient syndrome (陽虛證) induced by Hydrocortisone acetate (H.A.) in experimental animals (Mice and Rat), the author experimented various activities. Delayed type hypersensitivity (DTH), Rosette forming cells (RFC), hemagglutinin (HA) titers, Hemolysin (HL) titers, Body weight, Whole blood viscosity, Plasma Viscosity, Hematocrit, RBC, Albumin, Total protein, Triglyceride, cholesterol and Glucose were measured. The results summerized as follows; 1. In DTH and RFC all the experimental groups were increased significantly in comparison to the H.A.-treated group. 2. In HA titers SIT_treated group were increased significantly and KBT-treated group showed increasing tendancy, but showed no significance. 3. In HL titers all the experimental groups showed increasing tendancy, but showed no significance. 4. In body weight all the experimental groups showed increasing tendancy, but showed no significance. 5. In whole blood viscosity all the experimental groups were decreased significantly in comparison to the H.A.-treated group. 5. In whole blood viscosity all the experimental groups were decreased significantly in comparison to the H.A.-treated group. 6. In plasma viscosity KBT-treated group were decreased significantly and SIT-treated group showed decreasing tendancy, but showed no significance. 7. In Hematocrit SIT-treated group were decreased significantly and KBT-treated group showed decreasing tendancy, but showed no significance. 8. In RBC, albumin and cholesterol all the experimental groups were decreased significantly in comparison to the H.A.-treated group. 9. In total protein and triglyceride KBT-treated group were decreased significantly and SIT-treated group showed decreasing tendancy, but showed no significance. 10. In Glucose SIT-treated group were decreased significantly and KBT-treated group showed decreasing tendancy, but showed no significance. From above findings, it has been demonstrated that Sungyangikgibujat'ang and Kwangyebujalijungt'ang seem to produce the effectiveness on the recovery from depression of the cell-mediated immune response, blood circulation and energy metabolic rate, induced by Hydrocortisone acetate, and in the humoral immune response Sungyangikgibujat'ang have the effectiveness on the recovery, and in cellular component of blood Sungyangikgibujat'ang was more effective than Kwangyebujalijungt' ang, and in plasma of blood Kwangyebujalijungt'ang was more effective than Sungyangikgibujat'ang. Therefore it is suggested that Sungyangikgibujat'ang and Kwangyebujalijungt'ang have the effectiveness on the recovery from Yang-insufficient syndrome more or less.

  • A whole body physiologically based pharmacokinetic (PBPK) model was applied to investigate absorption, distribution, and physiologic variations on pharmacokinetics of imatinib in human body. Previously published pharmacokinetic data of the drug after intravenous (i.v.) infusion and oral administration were simulated by the PBPK model. Oral dose absorption kinetics were analyzed by adopting a compartmental absorption and transit model in gut section. Tissue/plasma partition coefficients of drug after i.v. infusion were also used for oral administration. Sensitivity analysis of the PBPK model was carried out by taking parameters that were commonly subject to variation in human. Drug concentration in adipose tissue was found to be higher than those in other tissues, suggesting that adipose tissue plays a role as a storage tissue for the drug. Variations of metabolism in liver, body weight, and blood/plasma partition coefficient were found to be important factors affecting the plasma concentration profile of drug in human body.

  • Phenanthrene, one of Polycyclic aromatic hydrocarbons with three aromatic rings, is a ubiquitous contaminant in the environment. Phenanthrene has been identified in ambient air, drinking water and sediment. We examined the effect of phenanthrene on steroid hormones level of olive flounder, Paralichthys olivaceus. Plasma testosterone level was increased significantly in fish exposed to phenanthrene($\geq1.0 \mu M$) at 4th week. However, there was no significant changes of estradiol-17$\beta$ concentration in fish exposed to phenanthrene. The physiological variation in phenanthrene exposed fish was a dramatic increase in plasma cortisol level. It is concluded that chronic exposure of phenanthrene can induce increase of plasma testosterone levels and elevate the plasma cortisol level in flounder, Paralichthys olivaceus.

  • It is now well established that transient granulocytopenia is common in patients during the initial phase of hemodialysis with new cuprophane membrane, but not with reused nembrane, or some synthetic membranes. In this study, new cuprophane dialyzer was treated with plasma and albumin, respectively, then, peripheral blood leukocytes were counted at the onset and after 15 minute of hemodialysis. In the plasma-treated group, the percent of leukopenia was less (41.3 %) than control group (71.3 %). In the plasmatreated group, the degree of leukopenia was close to that ot'control grou p. The protective factor, therefore is thought to be present in the plasma other than albumin fraction.

  • This study was performed to investigate the effect of a raw diet (RD) on blood glucose and immune function in non-diabetic (normal) and streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were assigned to four groups (normal control, normal RD, diabetic control and diabetic RD). The control groups and the RD groups were fed an AIN-diet and RD for four weeks, respectively. Weight gain was statistically lower in the RD groups than in the controls. Fasting plasma glucose was significantly lower in the diabetic RD group than in the diabetic control group. The $CD4^+$ T-cell population was higher along with the $CD4^+/CD8^+$ ratio of the mesenteric lymph nodes in the normal RD group compared to the other groups. It can be concluded that RD may reduce the plasma fasting glucose concentration in diabetic rats and improve mesenteric lymph node immune function in normal rats.
