Transcriptional regulation by nicotine in dopaminergic neurons.
Dopaminergic neurons in the substantia nigra pars compacta (SNc) degenerate in Parkinson's disease. These neurons robustly express several nicotinic acetylcholine receptor (nAChR) subtypes. Smoking appears to be neuroprotective for Parkinson's disease but the mechanism is unknown. To determine whether chronic nicotine-induced changes in gene expression contribute to the neuroprotective effects ...
متن کاملPT673. Pharmacological analysis of nicotine-induced tremor
s | 45 Methods: Gabapentin 10, 30mg/kg; diclofenac 5mg/kg(reference drug), vehicle(saline) were injected intraperitoneally before 100μl of 1% carrageenan administration into the right hind paws of the rats. Paw thickness was measured by a gauge calipers(Vernier Calipers) before (0th hour) and in every hour during 6 hours after induction of inflammation. Paw thickness of treated groups were comp...
متن کاملNicotine Prevents MPTP-induced Dopaminergic Neurodegeneration
Epidemiological studies of Parkinson disease (PD) have found an inverse correlation between cigarette smoking and the risk of developing PD, which suggests that nicotine has a protective effect. Results from animal models of PD are conflicting, raising questions about a protective potential of nicotine. In this study, mice were pretreated with low-dose nicotine before MPTP administration, and e...

In this investigation the effects of excess vitamin A administration during the early embryonic period were studied. Intramuscular injection of a single dose of 15000,20000 or 25000 IU/kg vitamin A to pregnant Balb/c strain mice on either day 7,8,9 or 10 of gestation (vaginal plug= day 0 of gestation) produced major malformations in the central nervous system (CNS) including exencephaly, h...
متن کاملInvolvement of the central catecholaminergic system in nicotine-induced tail-tremor in rats.
The effect of 6-hydroxydopamine on repeated nicotine-induced tail-tremor was investigated in rats. Tail-tremor induced by nicotine (0.5 mg/kg/day, subcutaneously) became more pronounced in intensity with daily administration for 9 days. Rats pretreated with 6-hydroxydopamine (250 micrograms, intracerebroventricularly) showed almost the maximum degree of tail-tremor during the whole experimental...
