Myocardial bridging with systolic compression of the left anterior descending coronary artery (LAD) may be associated with myocardial ischemia. In symptomatic myocardial bridging unresponsive to medical treatment, surgical unroofing of the left LAD can be performed. Little information is available about the long-term prognosis of patients with this coronary anomaly after the surgical unroofing,...

Diagnosis of hepatitis B is routinely based on of serological assay of hepatitis B surface antigen (HBsAg). Occult hepatitis B virus (HBV) infection is generally defined as the detection of HBV -DNA in the serum or tissues of subjects who have negative test for HBsAg. Transmission of HBV infection has been documented from HBsAg negative, anti-HBc positive blood and organ donors. The aim of this...

The central cholinergic system has been associated with cognitive function and memory and acetylcholine plays an important role during the early stages of memory consolidation. In this study, mice were trained with one way active avoidance procedure. Different doses of arecoline and physostigmine, with and without scopolamine, were administrated at pre-training, post-training and retrieval phas...

The Iranian, or Persian, calendar is solar, with the particularity that the year is defined by two successive, apparent passages of the Sun through the vernal (spring) equinox. It is based on precise astronomical observations, and moreover uses a sophisticated intercalation system, which makes it more accurate than its younger European counterpart, the Gregorian calendar. It is currently used i...

The histopathologic diagnosis of orbital and ocular adnexal lymphoproliferative lesions is difficult, resulting contraversy in classification, determining benignity or malignancy of them and treatment modality selection. We designed the following study to evaluate clinical, histopathologic and if necessary immunochemical features of them in decreasing indeterminate cases. The study includes 51 ...

Intrauterine insemination (IUI) has been widely used for the treatment of infertility. Several prognostic factors for IUI outcome have been proposed, including the endometrial thickness and follicle numbers, etiology and duration of infertility and morphology, type and motility of sperms. A total of 463 IUI cycles in which clomiphene citrate and/or human menopausal gonadotrophin (HMG) were used...

Intramascular (IM) administration of apomorphine ( a mixed D1/D2 dopamine receptors agonist ,0.2-1.6 mg/kg ) induced pecking,a stereotype behavior in pigeons in a dosedependent manner. In this study the effect of lithium (Li, 240 mg/kg, IM) and AMI-193(a new 5-HT2 antagonist, 0.003 mg/pigeon) on apomorphine-induced pecking (AIP) were investigated. This study showed that Li and AMI-193 did not i...

The effect of nerve growth factor (NGF) on regeneration of rat sciatic nerves in adult rat was studied. The sciatic nerve was cut out across a 6-mm gap, then the proximal and distal stumps were inserted into the silicone tube chamber. 7s NGF was extracted from submaxillary gland and then was injected into the silicone in experimental group. After seven months nerve was transected and stained wi...

It has been suggested since long that peripheral nerves possess opioid receptors and this has tempted clinicians in adding narcotics to local anesthetics to prolong the analgesic effects of these solutions. In this regard, we studied 45 patients undergoing surgical procedures on upper extremities. The patients scheduled for surgery were divided in to three groups, each comprising of 15 patients...

After using 3 different generations of antibody including human and non-human hyperimmune sera, monoclonal antibodies and Chimeric antibodies, more recently a newer approach has been developed in which the antibody genes are cloned directly from a patient peripheral Blymphocytes and expressed in a host like E. coli. In this study the Candida albicans serotype A (NCTC 3135) mannan was purified u...
