1. Melatonin decreases cocaine-induced locomotor activity in pinealectomized rats
Objective: Several studies have shown that the time of day regulates the reinforcing effects of cocaine. Additionally, melatonin and its MT1 and MT2 receptors have been found to participate in modulation of the reinforcing effects of such addictive drugs as cocaine. Loss of the diurnal variation in cocaine-induced locomotor sensitization and cocaine-induced

6. A newly validated HPLC–DAD-UV method to study the effects of medicinal plants extracts, fractions and isolate compounds on gastric emptying in rodents
Abstract In this study, we developed and validated a chromatographic method by High-performance Liquid Chromatography coupled to Diode-Array Ultraviolet Detector for quantification of acetaminophen in small volumes of plasma. This analytical method is particularly suitable for studies of gastric emptying time and pharmacokinetics in small rodents. Orally adm
