A rapid, linear, precise, selective and accurate reverse phase HPLC method was developed and validated for simultaneous estimation of glibenclamide in tablet dosage form. The method employed for analysis using methanol as a solvent. The wavelength UV 300 nm was selected for estimation and linearity was observed in the concentration range of 160 240 μg/ml for glibenclamide respectively. The reco...

The mutual role of glucose and insulin in the regulation of glucokinase and GLUT2 glucose transporter gene expression in pancreatic B-cells and liver has been studied in vivo in the rat. Glucokinase mRNA was quantified by competitive reverse-transcriptase PCR analysis, and GLUT2 mRNA by Northern-blot analysis in total RNA fractions. As in the liver, glucokinase mRNA decreased by 64% in pancreat...

ATP-sensitive potassium (K+ATP) channels have been shown to play a role in the maintenance of basal coronary vascular tone in vivo. K+ATP channels are also involved in the coronary vasodilator response to adenosine. The aim of this study was to determine the role of K+ATP channels in local metabolically mediated increases in coronary blood flow during cardiac electrical paired pacing without ca...

BACKGROUND Lipoic acid (LA) was shown to possess anti-inflammatory properties. In this study, we present evidence supporting the hypothesis that the anti-inflammatory properties of LA are associated with the formation of hydrogen sulfide (H2S). METHODS The study was conducted on male albino Swiss mice. The animals were treated with carrageenan by subcutaneous (sc) injection into the right hin...

Introduction: The potential of combining liquisolid and co-grinding technologies (liquiground technique) was investigated to improve the dissolution rate of a water-insoluble agent (glibenclamide) with formulation-dependent bioavailability. Methods: To this end, different formulations of liquisolid tablets with a wide variety of non-volatile solvents contained varied ratios of drug: solvent and...

Gestational diabetes mellitus (GDM) is a serious and frequent concern in pregnancy. Worldwide, the prevalence of GDM ranges from 8 to 20%. In 5% cases, this pathology accompanied by complications such as diabetic fetopathy, preeclampsia, neonatal hypoglycemia, hyperbilirubinemia. Modern national foreign guidelines for detecting hyperglycemia during pregnancy diagnosing recommend lifestyle chang...

Cardiac hypertrophy is a compensatory mechanism that occurs in conjunction with cardiovascular diseases. Although hypertrophy of the myocardium provides certain benefits during the early stages of cardiovascular disease, prolonged hypertrophy is potentially harmful to the heart and can result in arrhythmia and heart failure. The aim of this study was to investigate whether an ATP‑sensitive K+ (...

OBJECTIVES We sought to define effects of glibenclamide, a sulfonylurea known to block ATP-dependent potassium (KATP) channels, and Nomega-nitro-L-arginine methyl ester (L-NAME), an L-arginine analog known to block nitric oxide (NO) synthesis, on coronary vascular responsiveness to adenosine. BACKGROUND The role of adenosine in coronary flow regulation becomes increasingly important when KATP...

BACKGROUND AND PURPOSE Ischemia/hypoxia induces de novo expression of the sulfonylurea receptor 1-regulated NC(Ca-ATP) channel. In rodent models of ischemic stroke, early postevent administration of the sulfonylurea, glibenclamide, is highly effective in reducing edema, mortality, and lesion volume, and in patients with diabetes presenting with ischemic stroke, pre-event plus postevent use of s...

The dried sap of the aloe plant (aloes) is one of several traditional remedies used for diabetes in the Arabian peninsula. Its ability to lower the blood glucose was studied in 5 patients with non-insulin-dependent diabetes and in Swiss albino mice made diabetic using alloxan. During the ingestion of aloes, half a teaspoonful daily for 4-14 weeks, the fasting serum glucose level fell in every p...
