Incubation of rat hepatocytes with epinephrine inhibited alanine aminotransferase (ALT) (80%) and aspartate aminotransferase (AST) (53%) activities with no effect on lactate dehydrogenase (LDH) activity. Injection of epinephrine caused a progressive increase with time in hepatic LDH activity, being 52% at 24 h. Preinjection with propranolol eliminated the hormone effect and caused further ...

Abstract Background We investigated the role of epinephrine in prolonging localization lidocaine on oral mucosa and inhibiting its absorption blood rats. Methods used 7–8-week-old pathogen-free Wistar male rats (n = 128) for our study. divided them into control group administered with 14 C-labeled hydrochloride gel only study epinephrine. The medications were palatal amount mucosa, palatine bon...

In the title compound, C(9)H(11)BrN(2)O(5), the ribofuran-ose ring has a C2-exo, C3-endo twist configuration and is attached to the uracil unit via a β-N(1)-glycosidic bond. The crystal structure is stabilized by two inter-molecular O-H⋯O inter-actions and one inter-molecular N-H⋯O inter-action.

The title compound, C(6)H(12)O(6), also known as d-Tagatose, occurs in its furanose and pyranose forms in solution, but only the α-pyran-ose form crystallizes out. In the crystal, the molecules form hydrogen bonded chains propagating in [100] linked by O-H⋯O interactions. Further O-H⋯O bonds cross-link the chains.

The title compound, C(19)H(26)O(8)S, has been synthesized from 2,3:4,5-di-O-isopropyl-idene-β-d-fructopyran-ose. The absolute configuration of the fused ring is confirmed by anomalous dispersion effects in the diffraction measurement. The six-membered β-fructopyran-ose ring has a twist-boat conformation with the two five-membered rings trans to each other. In the crystal, inter-molecular non-cl...

Background: Duration of spinal anesthesia depends on the type of anesthetic agent, dosage and additive materials such as epinephrine, ephedrine and opioid. We compared the duration of spinal anesthesia with lidocaine 5% with or without epinephrine in addict and non-addict patients undergoing inferior limb fracture surgery. Methods: This single blinded randomized clinical trial was performed on ...

Introduction: Radiation therapy (RT) is the gold standard treatment for more than half of known tumors. There is increasing evidence that combining radiation therapy with a radiosensitizer can enhance the efficiency of this treatment modality. A radiosensitizer preferably enhances dose at the site of tumor and increases discrimination between tumor and normal surrounding tissue...

introduction lidocaine plus epinephrine is the most common anesthetic drug used in dentistry which has important cardiovascular side-effects like increase in blood pressure and cardiac arrhythmia. the goal of this study was to evaluat cardiovascular effects of one cartridge of 2% lidocaine + 1:80000 epinephrine. methods and materials 60 cases without any systemic diseases who had been admitted ...

abstract background: acute bronchiolitis is the most common form of lower respiratory tract infection in infancy. there are numerous contradictory reports regarding the efficacy of nebulized bronchodilators in the management of infants with acute bronchiolitis. this study was designed to compare the efficacy of nebulized epinephrine with salbutamol for treatment of the disease. methods: in a ra...
