It has been reported that interdigestive motor activities occur in the gallbladder and sphincter of Oddi as well as in the gastroduodenal tract and truncal vagus nerves modulate the gastroduodenal motility pattern. In the present study, the vagal branches which influence on the interdigestive motor activity of these organs were determined in conscious dogs. In the normal dog, interdigestive mot...

A 14-year-old who had 7episodes of relapsing unita­leral paralysis of facial nerve during 7 year-;. was admit­ted to the hospital. The X-Ray revealed Osteopetrosis, and the bone biopsy was proved this diagnosis. But there was not any bone fracture, or anemia. Pressure over fa­cial nerve caused by condensation of entire facial nerve canal. was detected by tomographia. Probablv intermitant facial...

In microsurgical nerve repair, the epineural sleeve technique can be used to bridge short nerve defects and to coverthe coaptation site with the epineurium of the nerve stump. The epineurium serves as a mechanical aid to reducegap size, and increase repair strength, effectively assisting nerve regeneration.This article presents a 32-year-old patient who experienced complete transection of the m...

Abstract Objective To report a case of abducens nerve palsy with associated retinal involvement due to rickettsia typhi infection. Material and methods A single documented multimodal imaging. Results 18-year-old woman history high-grade fever was initially diagnosed typhoid treated fluoroquinolone. She presented 5-day diplopia headaches. Her best-corrected visual acuity 20/20 in both eyes. Ocul...

background: considering the common origin of skin and peripheral nervous system, a tube of dermal layer of skin hypothetically can be an ideal conduit for nerve reconstruction. an experimental study performed to evaluate the nerve regeneration of efficacy into a dermal tube. methods: sixty male wistar rats were used. a 10 mm gap was produced in right sciatic nerves. in group a the autogenous ne...

Autograft is gold standard treatment for peripheral nerve repair up to now. Eggshell membrane (ESM) as nerve guide channel effectively enhances nerve regeneration. Dimethyl sulphoxide (DMSO) has anti-inflammatory and anti-oxidant properties. The aim of this study was to evaluate the effect of DMSO+eggshell membrane guide channel on sciatic nerve regeneration in rats. Thirty two adult male rats ...

background: lipid peroxidation is known to cause various impairments to sperm cells and may play a major role in the etiology of male infertility. asthenospermia is the main factor of male infertility and has significantly higher level of peroxidation than in normozoospermic males. materials and methods: using thiobarbituric acid (tba) assay procedure, we have determined the level of lipid pero...

Background: The median nerve is one of the most important branches of the brachial plexus. Due to the role of the median nerve in sensory and motor innervation of the forearm and hand in the upper limbs, its blood supply is very important. Awareness of variations in the blood supply pattern to this nerve reduces the incidence of necrosis and ischemia of the nerve during surgical and diagnostic ...

to compare the reproductive performance of the wild and cultured stocks of beluga, huso huso males, some spermatological parameters were measured including: sperm motility, sperm density, spermatocrit and also fertilization rate, hatching rate and larval growth and survival rates. the semen samples were sampled from 11 wild spawners and 12 cultured brooders. a half of each semen sample was allo...

introduction: sperm cryopreservation is widely used as a way of preserving the male sperm used in future artificial insemination and fertilization. despite all the recent advances in cryopreservation technology, sperm motility is negatively affected by freezing and the thawing afterwards. yet hyaluronic acid is believed to improve the vitality and motility of the sperm, enhancing the physiologi...
