background in spite of common usage of the inferior alveolar nerve block (ianb), this method has some well-defined restrictions. objectives the purpose of the present study was to compare these two techniques for the surgical removal of impacted lower third molars. patients and methods a total of 44 similarly impacted lower third molars (22 patients with two similar teeth) were selected. in eac...

background: many people suffer from nerve injury. the time consuming nature of the treatments makes the condition worse. therefore, finding a way to accelerate the process of nerve repair is very important. objective: to determine the effect of ultrasound on the acceleration of crushed peripheral nerve regeneration. methods: the experimental model included crushed rat’s sciatic nerve. 40 rats w...

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 ...

objective: to evaluate sensorimotor nerve damage in patients with maxillofacial trauma referring to taleghani hospital, tehran, iran methods: this cross-sectional study was conducted during a 2-year period from 2014 to 2012 in taleghani hospital of tehran. we included a total number of 495 patients with maxillofacial trauma referring to our center during the study period. the demographic inform...

It is well-known that severe deformation to metals causes a direct grain refinement of the matrix without special heat-treatments due to the mechanism of dynamic continuous recrystallization (DCR). However, the microstructural revolution during severe deformation is seemed to be different depending on the deformation mode, namely the direction of deformation. In general, multi-directional defor...

conclusions the study indicated advantages of this modified bier's block compared to the traditional one including ability to perform surgery on upper limb bones and considerable pain relief at surgical and tourniquet sites during the operation until one hour thereafter. results this study showed the presence of analgesia at surgical and tourniquet sites during the operation in 96% of patients,...

the purpose of this study was to investigate magnetic resonance imaging (mri) of the normal feline eyeand optic nerves using t1-weighted and t2-weighted images. a total of 6 healthy female domestic short haircats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. magnetic resonance imaging data werecollected using gemsow (philips) at a magnetic field strength of 1.5 t. dorsal, sagittal, a...

The effects of caerulin, a CCK receptor agonist, and proglumide, a receptor antagonist, on hyperalgesia induced by sciatic nerve ligation, was studied in mice. Tolerance to the morphine response was obtained 3,7, 14,21 and 28 days after unilateral sciatic nerve ligation. Maximum hyperalgesia was found 14 days after nerve ligation. Caerulin increased morphine antinociception in nerve-ligated ani...
