Six serotonin antagonists (pizotifen, mianserin, cyproheptadine, ketanserin, trazodone and methysergide) were tested in mice in a behavioral despair procedure. The behavioral despair procedure detects most antidepressant compounds. Pizotifen, mianserin and cyproheptadine were found to be active and the others were inactive. The serotonin binding potency at(More)
A permanent cell line, HSC-M1, was established from a child with advanced CD30 (Ki-1)+ anaplastic large-cell lymphoma (ALCL). Clinical features included irritability, fever, weight loss, tender lymphadenopathy, pneumonitis, neutrophilia, and bone marrow erythrophagocytosis. While HSC-M1 cells exhibited an immunophenotype characteristic of ALCL of T-cell(More)
Cryoprecipitate is still widely used to treat hemophilia A in developing countries. However, the yield of factor VIII is relatively low averaging, i.e. only 50%. We have attempted to enhance the yield by adding sodium citrate to the plasma following the method of Shanbrom and Owens (Blood 98, 2001, 60a). Fresh-frozen plasma (FFP) units were processed either(More)
BACKGROUND AND OBJECTIVES Cryoprecipitate has a wide application for use as a fibrin glue. In some situations, platelets are added to the preparation in order to enhance the fibrin glue. MATERIALS AND METHODS Fresh plasma was collected by apheresis from the same donor to produce 250 ml of platelet-rich plasma (PRP) or platelet-poor plasma (PPP) (n = 12(More)
INTRODUCTION In vitro methods for assessing stored platelets are time consuming and variably correlate with in vivo survival. We used the ADVIA 120 and the Thromboelastogram (TEG) to assess changes during storage to determine a correlation of the results with those of other commonly used measures. METHODS Platelet concentrates were tested at 1 and 5 days(More)
