The present study investigated the effects of microinjections of acetylcholine (a cholinergic agonist), physostigmine (a cholinesterase inhibitor), atropine (an antagonist of muscarinic cholinergic receptors) and hexamethonium (an antagonist of nicotinic cholinergic receptors) into the parafascicular nucleus of thalamus on the acute corneal nociception in rats. Acute corneal nociception was ind...

purpose: to compare clear corneal incision and scleral tunnel incision in terms of intraocular pressure (iop), post-operative inflammation, induced astigmatism, and corneal edema in phacoemulcification. methods: this non-controlled clinical trial was conducted on 78 eyes with senile cataract. a clear corneal incision was made in 40 eyes and a scleral tunnel incision was made in 38 eyes. all eye...

clinical studies suggest that essential oil of eugenia caryophyllata (clove) buds (eoec) is efficacious in the treatment of dental pain. in the present study, we investigated the analgesic and local anesthetic effects of eoec and its possible mechanisms of action in acute corneal pain in rats. eoec was extracted by hydro-distillation in a clevenger type apparatus from clove buds. the acute corn...

Background and Importance: Our learning curve during two decades of neurosurgical practice has been changed from an abstractive to a more meaningful and conductive state. In cases of fifth nerve neurinoma, pre-operative anatomopathologic diagnosis could lead us to a pre-planned program during and after the surgery to get the safe surgical result. Case Presentation: Representation of two comp...
