Objective(s): Melatonin, an important hormone secreted by the epiphysis, is a powerful anti-oxidant with a high potential to neutralize medical toxins. The goal of this study was to demonstrate the beneficial effect of melatonin on epididymal sperm and reproductive parameters in mice treated with acetylsalicylic acid (ASA).Materials and Methods:</stro...

This retrospective cohort study evaluated procedural efficiency and patient satisfaction in patients who had received propofol, midazolam/fentanyl/propofol (MFP), or midazolam/fentanyl, as sedation for either esophagogastroduodenoscopy or colonoscopy. Questionnaires about procedural times and patient satisfaction were administered. Use of propofol for colonoscopy resulted in shorter time (minut...

Propofol is a frequently used intravenous anesthetic agent. The impairment caused by propofol on the neural system, especially the hippocampus, has been widely reported. However, the molecular mechanism underlying the effects of propofol on learning and memory functions in the hippocampus is still unclear. In the present study we performed lncRNA and mRNA analysis in the hippocampi of adult mic...

BACKGROUND The principal site for elimination of propofol is the liver. The clearance of propofol exceeds hepatic blood flow; therefore, extrahepatic clearance is thought to contribute to its elimination. This study examined the pulmonary kinetics of propofol using part of an indocyanine green (ICG) recirculatory model. METHODS Ten sheep, immobilized in a hammock, received injections of propo...

We have studied the effects of methohexitone and propofol with and without alfentanil on seizure duration and recovery in this observer-blinded, prospective, randomized, crossover study involving 24 patients undergoing electroconvulsive therapy (ECT). Each patient had four treatment sessions, and received the following four i.v. regimens in random order: methohexitone 0.75 mg kg-1, methohexiton...

Propofol is a widely used anesthetic in the clinic while several studies have demonstrated that propofol exposure may cause neurotoxicity in the developing brain. However, the effects of early propofol exposure on cerebellar development are not well understood. Propofol (30 or 60 mg/kg) was administered to mice on postnatal day (P)7; Purkinje cell dendritogenesis and Bergmann glial cell develop...

Introduction: In elderly patients decrease in cognitive function after anesthesia has been reported in the literature for over a century. Various studies have implicated agents such as propofol and sevoflurane in the development of post-operative cognitive dysfunction. We evaluated the effect of pre-operative cognitive status by mini–mental state examination (MMSE), on consumption of propofol d...

BACKGROUND We aimed to measure propofol concentrations in exhaled air with an ion mobility spectrometer coupled to a multicapillary column for pre-separation (MCC-IMS). In addition, we aimed to compare the values of these measurements with serum propofol concentrations, as determined by gas chromatography-mass spectrometry (GC-MS). METHODS Thirteen patients, ASA I or II, undergoing elective E...

PURPOSE Propofol is one of the most commonly used sedatives in the intensive care unit (ICU) despite its undesirable hypotensive effects. The purpose of this study was to determine the effects of continuous intravenous (CIV) propofol on vasopressor requirements in mechanically ventilated patients with sepsis. MATERIALS AND METHODS A multicenter, retrospective, propensity-matched pilot study w...

Propofol is a short-acting anesthetic and generally is utilized for the induction and maintenance of anesthesia in pediatrics and adults. However, whether repeated use of propofol affects long-term cognitive function remains unclear. This study investigated the effects of propofol on cognitive function and hippocampal neuroapoptosis in neonatal rat. A total of 112 male newborn 7-day old Sprague...
