A quantitative method for the evaluation of ulcer healing has been developed. The method consists of calculating an ulcer healing efficiency ratio (zetaz) interpreted as the second derivative of the regenerated ulcer area over time. The zetaz value is in direct proportion to the acceleration of healing, and in inverse proportion to the initial ulcer area. In order to test this method, we measur...

A group of 133 patients treated for bleeding peptic ulcer in our Department, is reviewed. Within several hours of admission, all patients underwent upper gastrointestinal tract gastroscopy and obliteration of the bleeding ulcer. Bleeding gastric ulcers were found in 41 patients, and duodenal ulcers in 92 patients. Patients were classified according to the Forrest scale: IA - 11 patients, IB - 4...

gonadotropin-releasing hormone (gnrh) has neuromodulatory roles in central and peripheral nervous systems. the purpose of this study is to evaluate the effect of gnrh analog (buserelin) on peripheral nerve regeneration. forty adult male rats were divided into buserelin-treated, normal saline, sham surgery, and castrated + buserelin groups. the left sciatic nerve was crushed by a fine forceps an...

case presentation in this report, ultrasound-guided sciatic nerve block was performed in a 25-year-old patient with tetanus to progress his respiratory drive which was decreased due to high dose sedative administration. this procedure accelerates the weaning process and extubation. introduction muscle rigidity and generalized spasm can cause severe pain in patients with tetanus. administration ...

to evaluate the effects of local administration of the fetal brain extract (fbe) on the crushed peripheral nerve, 15 male wistar rats were used. the right sciatic nerve of 10 rats was locally underwent the tense compression for 30 seconds and then randomly divided into experimental and control (sham) groups. the remained rats were considered as intact animals. treatment was commenced weekly, by...

introduction: arteriovenous fistulas (avf) make chronic hemodialysis easy, but the complications are unpredictable. ischemic neuropathy due to arterial insufficiency is one of the most important complications of avf. this study was designed to evaluate ischemic neuropathy using electro diagnostic method in the extremity carrying fistula. methods: in this cross-sectional study, 37 hemodialysis p...

introduction: the brachial plexus is responsible for the innervation to the upper limb and some parts of the thorax. variations in the branching of the brachial plexus are common and have been reported in 65.3% of the population. the variations (atypical communication) of brachial plexus have significant clinical and surgical importance. methods: in this study 10 upper limbs which belonged to 5...

footdrop is a relatively common deficit among the neurological disorders, which has different causes with various levels of involvement in neuromuscular system, including central nervous system (brain cortex, spinal cord), fifth lumbar root, peripheral nerves and muscles. peroneal nerve injury at the fibular head has been reported to the most common cause of foot drop, which can be due to infar...

conclusions our anesthesia method was sciatic and femoral nerve block under double ultrasonic and nerve stimulator guidance. case presentation in this case report, we present a patient who had tibia and fibula fractures and a symptomatic severe critical aortic stenosis which was diagnosed during a preoperative visit. the patient had exertional dyspnea, palpitations and fainting history, but he ...

excessive scarring; paralleling the process in tendon reconstruction of the hand. inspired by the advantages of the two-stage technique in tendon grafting and with encouraging preliminary results, we aimed to investigate the two-stage nerve grafting technique as an alternative method of secondary nerve repair. methods:  thirty female rats (~200 g) were randomly distributed into two groups (n=15...
