An Assay Method for Leukocyte Pyrogen
A method for assaying leukocyte pyrogen is described which is shown to remain valid despite the presence of very large amounts of bacterial endotoxin. It uses a combination of two procedures to inactivate endotoxin: incubation in normal rabbit plasma for 24 hr at 37 degrees C, and injection into rabbits rendered refractory to endotoxin. The validity of the assay was confirmed by formal statisti...
متن کاملIntracerebroventricular injection of rats: a sensitive assay method for endogenous pyrogen circulating in rats.
OI! Abstract, Intracerebroventricular tics) injection of endogenous pyrogen (EPI into rats causes dose-related fever. To compare this procedure with the usual assay method. iv 0 injection into rabbits, a preparation ofcrude rabbit EP was titrated by both methods. The rat f icy injection procedure gave results similar in linearity and magnitude of response to the conventional rabbit iv method, b...
متن کاملAn assay method for ferrichrome.
The isolation, chemical nature, and biological activity of the new iron compound ferrichrome have been reported elsewhere (l-3). Biochemical interest in ferrichrome centers, at present, around (a) its growth factor activity for PiZobolusl and (b) its possible relationship to cytochrome c formation in Ustilago sphaerogena. A suitable assay method for ferrichrome has been much desired as an aid t...
متن کاملAn improved fluorometric leukocyte beta-glucosidase assay for Gaucher's disease.
Three fluorometric leukocyte beta -glucosidase assays were compared for their ability to diagnose Gaucher's disease and identify carriers of the disorder: the acid beta-glucosidase assay of Beutler and Kuhl [2], a pH 5.5-sodium taurocholate-dependent assay and a new procedure which employs conduritol B epoxide, an active-site specific inhibitor of glucocerebrosidase. All three assays unambiguou...
متن کاملLeukocyte Detection Through an Evolutionary Method
Classical image processing methods often face great difficulties while dealing with images containing noise and distortions. Under such conditions, the use of soft computing approaches has been recently extended to address challenging real-world image processing problems. The automatic detection of Leukocytes or White Blood Cells (WBC) still remains as an unsolved issue in medical imaging. The ...
