Background:
Nicotine is heavily used addictive drug that has unpleasant side- effects, e.g. dizziness, nausea, emphysema.
Purpose:
The current study was designed to find the possible relationship of nicotine mediated microcystic oedema in white matter of cerebellum to postural imbalance.
Methods:
Nicotine was administered for 8 weeks orally via cannula, using dose rate (5 mg/day, 10 mg/day) to male drukrey rats. The results were compared to control adult rats, given vehicle in identical manner. After 8 weeks exposure, the cerebellum was removed and processed for histopathologic study.
Results:
The cellular microcystic change with interstitial oedema was found in white core of cerebellum of rat received 10 mg/kg of nicotine. Cytoplasmic vacuolation was also observed in most areas of cerebellum.
Conclusion:
These findings suggest that the mature adult cerebellum is susceptible to the damaging effects of nicotine in depleting white core of cerebellum.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...
