Responder cells [C57BL/6J X A.TL)F1 lymph node cells depleted of bursa equivalent-derived (B) cells by filtration through nylon wool columns] were activated against incompatible K-region and I-region products together under conditions where these antigens are presented on separate stimulator cells. The resulting T blasts were stained with different concentrations of antisera directed against in...

premature ovarian failure (pof) is a heterogeneous syndrome with several causative factors. autoimmune mechanisms are involved in pathogenesis of 4-30 % of pof cases. the present review focuses on the role of autoimmunity in the pathophysiology of pof. the evidences for an autoimmune etiology are: demonstration of ovarian autoantibodies, the presence of lymphocytic oophoritis, and association w...

background: previous studies have reported the antifertility activities of sulfonamides. this study was designed to evaluate the effects of co-trimoxazole and its co-administration with folic acid on ovarian tissue in female rats. methods: a total of 54 rats were randomly divided into 9 groups (n=6) . group i served as the control and group ii (vehicle) received saline. other groups, iii to ix,...

background: the best management for an ovarian mass is provided by appropriate prediction of malignancy. the aim of our study is to construct and validate a new malignancy probability score based on four simple sonographic findings and age. methods: in a cross sectional study; histopathological files of 3303 ovarian mass patients and tertiary hospitals, have reviewed within 6 years (2000-2006)....

BACKGROUND Two methods of nerve block based on eliciting neural feedback with the block needle currently exist. The paresthesia technique uses sensory feedback to ascertain that the needle tip is close to the nerve. By contrast, a peripheral nerve stimulator makes use of motor responses to electrical stimulation. The relation of motor responses to an electrical peripheral nerve stimulator and s...

BACKGROUND Coracoid approach is efficient and safe for brachial plexus block, and is guided by nerve stimulator or ultrasound in general. Many trials have proved that ultrasonic guidance was more efficacious than nerve stimulator guidance. We hypothesized that positioning posterior cord could enhance the anesthesia effect of coracoid approach brachial plexus block (CABPB) guided by nerve stimul...

The specificity of binding of stimulator-derived H-2 antigens by mixed lymphocyte culture (MLC)-activated T blasts was investigated under conditions of antigen excess. We have shown that the detectable proportion of alloantigen-binding blasts from primary MLC is a function of antigen concentration, and can represent up to more than 90 percent of total blasts, when the antigen is presented in th...

A comparative study between anatomical landmark and nerve stimulator guided supraclavicular brachial plexus block for neurovascular variations in topographic anatomy of brachial plexus. In the backdrop of our country, nerve stimulator is still not available in many centres and many anesthetists do not yet have the proper expertise and experience in giving nerve stimulator guided brachial plexus...

in the present report, diagnosis and treatment of a case with follicular ovarian cysts in a 5-year-old persian queen cat is described. in response to palpation of spines, the queen cat presented herself in lordosis and danced up and down with her rear legs. trans-abdominal ultrasonography examination showed 2 cysts  in the left ovary of the queen. serum estrogen assay indicated elevated level o...

The implanted peripheral nerve stimulator has a role for pain relief in well-selected patients with pain in a peripheral nerve distribution. We describe an electrode to help simplify the surgical implantation of a peripheral nerve stimulator and also to reduce the possibility of electrode migration following implantation. Design details of the electrode are discussed, as are notes on surgical t...
