Purpose: To determine the etiologic factors on rejection and failure rates and ocular surface changes after corneal transplantation by either DALK or PKP, in cases of keratoconus (KCN). Methods: In this cross-sectional study, considering the existing data, patients with keratoconus referring to Labbafinejad Medical Center from 2006 to 2016, who underwent corneal transplantation, were enrolled a...
Polyamines (putrescine, spermidine and spermine) are important endogenous regulators of ion channels, such as vanilloid (TRPV1), glutamatergic (NMDA or AMPA/kainate) and acid-sensitive (ASIC) receptors. In the present study, we have investigated the possible nociceptive effect induced by polyamines and the mechanisms involved in this nociception in vivo. The subcutaneous (s.c.) injection of cap...
Highly branched class IV multidendritic sensory neurons of the Drosophila larva function as polymodal nociceptors that are necessary for behavioral responses to noxious heat (>39 degrees C) or noxious mechanical (>30 mN) stimuli. However, the molecular mechanisms that allow these cells to detect both heat and force are unknown. Here, we report that the pickpocket (ppk) gene, which encodes a Deg...
Background: Keratomycosis is a fungal infection of the cornea which could be sight-threatening and even causes eye loss. Considering the high humidity and the dominance of agriculture as important predisposing factors of keratomycosis in north of Iran, this study was carried out for diagnosis of fungal keratitis in patients with corneal lesions in Rasht, Gilan province, Iran. Methods: This de...
Background: In this study were focused on corneal cells changes in keratoconus disease, as there are differences between results of other studies that were done on keratokonic eyes. And the chief purpose was a comparison between keratoconus and normal population based corneal endothelium (in cell density, pleomorphism and polymegethism of cells). Methods: This study is an observational study a...
This study was performed to evaluate the efficacy of anterior keratoplasty with microkeratome in the improvement of visual acuity (V.A) in superficial corneal disorders in patients admitted to Labbfi Nezhad hospital and Tehran Bassir Clinic . &nbs...
Background: Keratoconus is a common complication among corneal defects. As a result of expeditious and extensive progress of medical science in recent decades, corneal ring implantation has turned into a successful surgical procedure to correct the vision of Keratoconus patients; however, selecting the right patient is essential in the success of the operation. The prediction of corneal conditi...
BACKGROUND Dezocine is a powerful analgesic that can be less addictive than morphine, yet how the two drugs interact in vivo is poorly understood. Here we administered dezocine alone or in combination with morphine to different acute nociception paradigms to explore the interactions of the 2 drugs upon co-administration. OBJECTIVE To evaluate how dezocine interacts with morphine in different ...
