We investigated the quantitative alterations in retrograde transport of proteins following a nerve crush injury using the 3H N-succinimidyl propionate (3H NSP) method in rat sciatic nerve. After subepineurial injection of 3H NSP into the nerve the amount of radioactively labeled proteins accumulating in the cell bodies of the motor and sensory neurons was determined 1 day or 7 days later in ner...

The activities of uridine kinase (EC 2.7.1.48), uridine monophosphate (UMP) kinase (EC 2.7.1.3.14), and uridine diphosphate (UDP) kinase (EC 2.7.4.6) were measured in retinal high-speed supernatant fractions following unilateral optic nerve crush in the goldfish. The enzyme activities followed a similar time course, with initial increases 2-3 days following nerve crush, peak activity at 4 days,...

PURPOSE To investigate the effect of bilberry extract anthocyanins on retinal ganglion cell (RGC) survival after optic nerve crush. Additionally, to determine details of the mechanism of the neuroprotective effect of bilberry extract anthocyanins and the involvement of endoplasmic reticulum stress suppression in the mouse retina. MATERIALS AND METHODS Anthocyanins in bilberry extract (100 mg/...

INTRODUCTION Ozone may promote moderate oxidative stress, which increases antioxidant endogenous systems. There are a number of antioxidants that have been investigated therapeutically for improving peripheral nerve regeneration. However, no previous studies have reported the effect of ozone therapy on facial nerve regeneration. OBJECTIVE We aimed to evaluate the effect of ozone therapy on fa...

OBJECTIVE Crush injury to the sciatic nerve causes oxidative stress. Alfa Lipoic acid (a-LA) is a neuroprotective metabolic antioxidant. This study was designed to investigate the antioxidant effects of pretreatment with a-LA on the crush injury of rat sciatic nerve. METHODS Forty rats were randomized into four groups. Group I and Group II received saline (2 ml, intraperitoneally) and a-LA (1...

The ant (Pheidole megacephala, Fabricius) has a unique and hard mandibular structure to cut branches crush food. Inspired by this special geometric of the teeth, stereoscopic microscope was used view image mandible ant. Origin AutoCAD software were obtain outer profile teeth ant's fitted expressed five-order polynomial function. According analysis curve maxillary fourth tooth is most convex sha...

a common cause of peripheral nerve injury is trauma. the positive effect of antioxidants on the improvement of nerve regeneration has currently become a focus of attention. in this experiment, the effect of intraperitoneal administration of ubiquinone (coq10) on an acute experimentally sciatic nerve crush was studied in a rat model. forty-five male wistar rats, weighing between 160-180 g were u...
