We investigated the mode of the 5-HT3-receptor antagonism of 4,5,6,7-tetrahydrobenzimidazole derivatives, YM060, YM114 (KAE-393), YM-26103-2 and YM-26308-2, against 5-HT-induced transient bradycardia in anesthetized rats. Results were compared with those of ondansetron and granisetron. YM060 (0.03-0.1 microgram/kg, i.v.), YM114 (0.03-0.3 microgram/kg, i.v.), YM-26103-2 (0.01-0.03 microgram/kg, ...
Various flavonoids (in Europe, quercitin glucoside and its semisynthetic derivatives, especially) are used in treating varicosity. Nevertheless, we still lack almost all pharmacokinetic data on these substances, mainly because of analytical difficulties. Flavonoids were first measured spectrophotometrically (1) and later fluorometrically by the formation of a borocitric complex (2). Porter et a...
A novel modified Fenton process using heterogeneous catalyst (swarf) was developed to catalyze the oxidation reaction of azo dye Acid Red 18. It was found that swarf could be used to replace iron salts as a catalyst for the Fenton reaction. The examined continuous Fenton process proved to be very efficient for decolorization of simulated wastewater containing 100 mg/dm3 Acid Red 18. Performance...
INTRODUCTION Approximately 30% of juvenile idiopathic arthritis (JIA) patients fail to respond to anti-TNF treatment. When clinical remission is induced, some patients relapse after treatment has been stopped. We tested the predictive value of MRP8/14 serum levels to identify responders to treatment and relapse after discontinuation of therapy. METHODS Samples from 88 non-systemic JIA patient...
An isocratic reversed-phase high-pressure liquid chromatographic method for the determination of six components of the teicoplanin complex in biological fluid was developed. By using fluorescence detection after precolumn derivatization with fluorescamine, the assay is specific and highly sensitive, with reproducibility studies yielding coefficients of variation ranging from 1.5 to 8.5% (at 5 t...
Illumination of previously darkened maize (Zea mays L. cv Golden Cross Bantam T51) leaves had no effect on the concentration of phosphoenolpyruvate (PEP) carboxylase protein, but increased enzyme activity about 2-fold when assayed under suboptimal conditions (pH 7.0 and limiting PEP). In addition, sensitivity to effectors of PEP carboxylase activity was significantly altered; e.g. malate inhibi...
چکیده : * در یک واکنش تک ظرفی و با استفاده از واکنش آلدهید های آروماتیک و 3- متیل 1- فنیل پیرازولین-5- ان با نسبت مولی 1:1، ساختارهای هتروسیکل پیرازول سنتز شد. از مزایای آن، انجام واکنش در دمای اتاق، عدم نیاز به کاتالیزور، بازده بالای واکنش، استفاده از آب بعنوان حلال سبز و بی خطر به جای حلال های آلی وسمی می باشد . * توانستیم با استفاده از ملدرام اسید ومشتقات 2- هیدروکسی بنزآلدهید، ترکی...
In dogs, intracoronary doses of CV-1674, adenosine ( ADS) and 2-Cl-ADS for doubling coronary flow were estimated as 5.0, 2.0 and 0.4 microgram/dog, and i.v. doses 31, 71 and 2.5 microgram/kg, respectively. ADS and 2-Cl-ADS decreased, while CV-1674 increased LV dp/dt. Intravenous infusion (30 min) of CV-1674 (10 microgram/kg per min) and ADS (700 microgram/kg per min) decreased coronary resistan...
The modulation of the cytotoxic effects of an anthracyclin by CD40L was investigated in five non-Hodgkin's lymphoma (NHL) cell lines (Daudi, Raji, BJAB, BL36, BL70). Incubation with doxorubicin (DOX) increased in a dose-dependent manner the percentage of apoptosis in NHL cells. Coculture with irradiated L cells expressing CD40L (CD40L L cells), but not CDw32 (CDw32 L cells), significantly reduc...
