The localization of cytochrome P-450 4A, peroxisome proliferator-activated receptor (PPAR) alpha, and PPARgamma proteins, and the inducibility of P-450 4A expression and activity by PPAR agonists were determined in the rat kidney. The expressions of these proteins in isolated nephron segments were evaluated by immunoblot analysis, and the production of… (More)
Members of the cytochrome P-450 4 (CYP4) family catalyze the omega-hydroxylation of fatty acids, and some of them have the PPAR response element in the promoter area of the genes. The localization of CYP4A and PPAR isoforms and the effect of PPAR agonists on CYP4A protein level and activity were determined in rat kidney and liver. Immunoblot analysis showed… (More)
OBJECTIVE To demonstrate that the administration of an angiotensin (Ang) II type 1 receptor (AT1R) blocker (ARB) inhibits the vicious cycle of high glucose (HG)-reactive oxygen species (ROS)-angiotensinogen (AGT)-Ang II-AT1R-ROS by suppressing ROSs and inflammation, thus ameliorating diabetic nephropathy (DN). RESEARCH DESIGN AND METHODS Thirteen… (More)
BACKGROUND AND OBJECTIVES Sarpogrelate has been shown to reduce albuminuria in diabetic nephropathy. For examination of whether this is based on the same mechanisms as angiotensin II receptor blockers or thiazolidinedione, effects of sarpogrelate on atherosclerotic inflammatory molecules and their relations to albuminuria in patients who had diabetes and… (More)
The role of androgens in the production of 20-hydroxyeicosatetraenoic acid (20-HETE) was determined in the kidney of spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY). The renal production of 20-HETE and blood pressure were higher in males than in females at 9 weeks of age. The renal production of 20-HETE was significantly greater in male… (More)
We encountered two patients who developed daytime hyperglycemia and early morning hypoglycemia because of insulin antibody (IA) that the affinity was extremely lower and the capacity extremely higher than those of IA in the insulin autoimmune syndrome, after their insulin treatment were changed from human insulin to analog insulin.
This report puts forward a method of powder X-ray diffractometry to estimate the precision and detection limit of the crystalline component in an amorphous drug. Cefditoren pivoxil (CP) was employed as a model drug. The major error source of the measurement at low crystal contents is shown to be the random noise in a diffraction pattern (halo pattern) of… (More)
