We assessed the effects of heptyl physostigmine, a new cholinesterase inhibitor, in a mouse tail-flick (TF) test, a mouse and rat passive avoidance test, a rat conditioned suppression-of-drinking (CSD) test, a rat Random Interval (RI) response rate test and a rat delayed matching-to-position (DMTP) test. In the TF test, a dose of 8.0 mg/kg of heptyl induced(More)
Two experiments examined the effect of the benzodiazepine receptor agonist, zolpidem, on palatable fluid intake in water-deprived rats. In the first experiment, pretreatment with 3.0 or 10.0 mg/kg zolpidem IP was found to increase consumption of a novel glucose drink (3% d-glucose and 0.1% sodium saccharine w/v in water). The increase in fluid consumption(More)
Tropical peatlands represent globally important carbon sinks with a unique biodiversity and are currently threatened by climate change and human activities. It is now imperative that proxy methods are developed to understand the ecohydrological dynamics of these systems and for testing peatland development models. Testate amoebae have been used as(More)
