introduction: malignant tumors of the parotid gland account scarcely for 5% of all head and neck tumors. most of these neoplasms have a high tendency for recurrence, local infiltration, perineural extension, and metastasis. although uncommon, these malignant tumors require complex surgical treatment sometimes involving a total parotidectomy including a complete facial nerve resection. severe fu...

Since the quality of sperm is affected by water industrial or agriculture pollution, sperm motility was measured as a sensitive and accurate bioindicator of water quality. In this study, sperm motility was measured by a computer assisted sperm analysis after 24 hours exposure of sperm to different concentration of heavy metals) Cadmium and Zinc). The results show that the sperm motility was not...

Peripheral nerve injury requires a long recovery period, and recovery, once attained, usually is incomplete. Inflammatory procedures may inhibit functional recovery after nerve injury and produce cell death in both the central nervous system and the peripheral nervous system. Since the glycyrrhiza glabra extract has anti-inflammatory effects, it could reduce the severity of injury. The aim of t...

PURPOSE High-resolution, multipositional magnetic resonance imaging (MRI) was used to demonstrate extraocular muscles (EOMs) and associated motor nerves in Duane retraction syndrome (DRS) linked to the DURS2 locus on chromosome 2. METHODS Five male and three female affected members of two autosomal dominant DURS2 pedigrees were enrolled in the study. Coronal T(1)-weighted MRI of the orbits wa...

objective: to assess the effect of combination of pulsed electromagnetic fields (pemf) with predatory stress on transected sciatic nerve regeneration in rats.  methods: in sham- operated group (sog) the nerve was manipulated and left intact. the 10-mm rat sciatic nerve gap was created in rats. in transected group (transected) nerve stumps were sutured to adjacent muscle and in vein graft group ...

atypical connections in the formation of the brachial plexus are prevalent and have been reported in different articles. the present report describes a case of variation of the median nerve observed in the iranian male cadaver during routine trial dissection. there are three roots for median nerve. median nerve is formed by joining two lateral and medial cords of brachial plexus. third root of ...

introduction: the effect of esophageal distension (ed) on gastric motility has been well documented, but a few investigations have been carried out on the effect of ed on gastric secretion. the aim of this study was to investigate the effect of ed on gastric acid and pepsin secretion and the mechanism(s) involved. methods: male adult wistar rats (200-240 g) were anesthetized with urethane (1.2 ...

Objective- The objective was to assess local effect of brain derived neurotrophic factor (BDNF) on functional recovery of peripheral nerve in rat sciatic nerve transection model. Design- Experimental study. Animals- Sixty male healthy white Wistar rats Procedures- The animalswere randomized into four experimental groups of 15 animals each: In sham-operated group (SHAM), sciatic nerve was exp...
