The purpose of the present study was to determine the minimal arecaidine concentrations showing a synergistic effect on DMBA-induced hamster cheek pouch carcinogenesis. One hundred and twelve male adult Syrian golden hamsters were divided into 16 groups, each containing seven animals. After eight
OBJECTIVE
Spontaneous in vivo phasic contractions are suppressed during ileal inflammation. The aim of this study was to test the hypothesis that modulation of the contractile response to muscarinic receptor activation contributes to this inhibition.
METHODS
Muscarine, methacholine, and arecaidine
Previous data from our laboratories using the mouse air pouch model demonstrated that intrathecal injection of the cholinomimetic drug, neostigmine, produces a significant peripheral anti-inflammatory effect through activation of spinal muscarinic type 2 receptors. This anti-inflammatory effect is
Muscarinic acetylcholine receptors (mAChRs) have been widely reported as pharmacological targets for the treatment of pain. However, most of these efforts have focused on CNS mAChRs and their role in modulating nociception at the level of the spinal cord. The present study examines the contribution
The peripheral application of the M2 cholinergic agonist arecaidine on sensory nerve endings shows anti-nociceptive properties. In this work, we analyze in vitro, the mechanisms downstream M2 receptor activation causing the analgesic effects, and in vivo the effects produced by M2 agonist arecaidine
OBJECTIVE
To evaluate a modified method of carcinogenesis induction using the 9,10-dimethyl-1,2-benzanthracene (DMBA) sustained-release suture technique followed by arecaidine promotion in the hamster cheek pouch model.
METHODS
Prospective, controlled animal study.
METHODS
Number 3-0 cotton sutures
Oral submucous fibrosis (OSF) is a chronic inflammatory disease characterized by the accumulation of excess collagen, and areca nut chewing has been proposed as an important etiological factor for disease manifestation. Activation of transforming growth factor-β signaling has been postulated as the
