Using a electrophysiological model that has been employed to screen compounds for antipsychotic potential, we and others have shown that the chronic administration of the 5 HT3 receptor antagonists like MDL 73,147EF, LY 277359 and granisetron creates Fingolimod a reduce in the amount of spontaneously energetic midbrain dopamine ceils in the rat. Due to the fact these resuhs are similar to those obtained with typical and atypical antipsychotic medication, they suggest that 5 HT3 receptor antagonists may well have antipsychotic potential. However, not like conventional antipsychotic medication, LY 277359 and granisetron tend not to inactivate dopamine cells by depolarization block as their suppressant action will not be reversed from the systemic administration of apomorphine. In fact, in rats treated chronically with either granisetron or LY 277359, the administration of apomorphine fully suppressed AlO dopamine cell activity, suggesting that LY 277359 and granisetron potentiate apomorphines inhibitory action to the dopamine neurons.
The respective control groups were treated with solvent Cell Cycle inhibitor The results were presented as the body temperature changes relative to the average temperature obtained from two preliminary measurements determined before the FLU treatment The temperature was recorded over 2 h at 30 min intervals The body temperature was measured as above m CPP was given 30 mm before the test. The control animals were given the solvent The temperature was recorded over a period of 2. 5 h Observation of the exploratory activity in the open field was made according to Janssen et al.. m CPP was injected 30 min before the test. The control animals were given the solvent. Each animal was observed for 3 mm. L 5 HTP was given 3 h after injection of pargylme. Head twitches were recorded by the method of Corne et al.
Segments of 3 cm in length were placed in a 25 ml organ bath containing Krebs Henseleit solution aerated with 95% O2 and 5% CO2, and maintained at 37 C. Tissues were placed under an NSCLC initial tension of 1 g. Agonists were added to the bath for 30 s, and the contractions were recorded isometrically, using a force displacement transducer. When used, the antagonist tropisetron was added 30 s before the agonist. Male Crl:CD BR rats weighing 280 320 g were fasted for 24 h and then anaesthetised with urethane. In order to monitor the Bezold Jarisch reflex, the carotid artery was cannulated and connected to a Statham transducer, as described by Richardson et al.. Heart rate and blood pressure were measured by using the pressure transducer signal and a cardiotachometer coupler, and recorded onto a Gemini polygraph.
