Inflexinol, an ent-kaurane diterpenoid, was isolated from the leaves of Isodon excisus. Many diterpenoids isolated from the genus Isodon (Labiatae) have antitumor and antiinflammatory activities. We investigated the antiinflammatory effect of inflexinol in RAW 264.7 cells and astrocytes. As a result, we found that inflexinol (1, 5, 10 microM) suppressed the(More)
BACKGROUND Bee venom therapy has been used to treat inflammatory diseases including rheumatoid arthritis in humans and in experimental animals. We previously found that bee venom and melittin (a major component of bee venom) have anti-inflammatory effect by reacting with the sulfhydryl group of p50 of nuclear factor-kappa B (NF-kappaB) and IkappaB kinases(More)
Tumors of the liver and biliary tree, mainly hepatocellular carcinoma and cholangiocarcinoma, are the second leading cause of cancer related death worldwide and the sixth leading cause of cancer related death among men in developed countries. Recent developments in biomarkers and imaging modalities have enhanced early detection and accurate diagnosis of(More)
Cytomegalovirus (CMV) infection occurs in a large proportion of transplant patients and is the most common viral cause of clinical disorders in these patients. In particular, CMV esophagitis is the second most common gastrointestinal (GI) manifestation , next to colitis. No patient is asymptomatic, and the clinical manifestations include difficult or(More)
The objective of the present investigation is to examine the effects of rifampicin, which is a P-glycoprotein (P-gp) and cytochrome P450 (CYP)3A4 inducer, on the pharmacokinetics of risperidone and its active metabolite, 9-hydroxyrisperidone, in rats. To determine the plasma levels of risperidone and 9-hydroxyrisperidone in rats, a high performance liquid(More)
The aim of this study was to investigate the effects of formulation vehicles on the pharmacokinetics of docetaxel. The following three formulations of docetaxel were prepared to compare the pharmacokinetic profiles of docetaxel: Tween® 80 formulation (a vehicle composition of Taxotere®), Cremophor® EL formulation (a vehicle composition of Taxol®) and DMSO(More)
A nanohybrid was prepared with an inorganic clay material, montmorillonite (MMT), for taste masking of sildenafil (SDN). To further improve the taste-masking efficiency and enhance the drug-release rate, we coated the nanohybrid of SDN-MMT with a basic polymer, polyvinylacetal diethylaminoacetate (AEA). Powder X-ray diffraction and Fourier transform(More)
