Adenosine receptor[1]

In Vivo After the administration of 5'-N-Ethylcarboxamidoadenosine (NECA), the mean number of cocaine infusions obtained per session is decreased significantly in a dose-dependent manner [5'-N-Ethylcarboxamidoadenosine (NECA): F(4,12)=14.9; P<0.001]. The administration of 5'-N-Ethylcarboxamidoadenosine (NECA) [F(4,12)=16.1; P<0.001] results in a significant increase in latencies above values obtained for vehicle treatment[1]. Daily i.p. injection of 5'-N-Ethylcarboxamidoadenosine (NECA) at 0.3 mg/kg/day for two weeks reduces malondialdehyde (MDA) levels in diabetic rats, but does not affect control rats. Daily treatment with NECA (0.3 mg/kg/day, i.p. for two weeks) reduces diabetes-induced gene expression of tumor necrosis factor (TNF)-α and interleukin (IL)-18 in diabetic rats, but does not affect control rats. Daily i.p. injection of 5'-N-Ethylcarboxamidoadenosine (NECA) at 0.3 mg/kg/day for two weeks also blocks the activation of JNK MAPK in diabetic rats, but does not affect control rats[2].
Animal Admin Male Wistar rats are used in this experiment. These animals range in weight between 350 and 425 g. They are housed individually in hanging wire cages under a 12-h light/dark cycle. The effects of 5'-N-Ethylcarboxamidoadenosine (NECA) are tested in four rats. In the experiment, either 5'-N-Ethylcarboxamidoadenosine (NECA) (5, 7.5, 10, 20 μg/kg) or vehicle (saline) is administered intraperitoneally 15 min prior to the start of test sessions. 5'-N-Ethylcarboxamidoadenosine (NECA) is administered following a random order crossover design. In most cases, animals are tested twice with the same dose[1].
