A reliable procedure is described for isolating 3H-triamcinolone acetonide (3H-TA) receptor complexes from purified chronic lymphatic leukemia (CLL) lymphocyte nuclei, based on the use of carbobenzoxy-L-phenylalanine (CBZ-L-phe) to prevent breakdown of hormone-receptor complexes during extraction of nuclei with 0.6M KCl. Using this method, specific nuclear glucocorticoid binding was demonstrated in 14/14 patients with untreated CLL. No correlation was found between levels of nuclear-associated 3H-TA and peripheral white blood cell count or rosetting ability of circulating lymphocytes.
This toxicological profile is prepared in accordance with guidelines developed by the Agency for Toxic Substances and Disease Registry (ATSDR) and the Environmental Protection Agency (EPA). The original guidelines were published in the Federal Register on April 17, 1987. Each profile will be revised and republished as necessary. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for these toxic substances described therein. Each peer-reviewed profile identifies and reviews the key literature that describes a substance's toxicologic properties. Other pertinent literature is also presented, but is described in less detail than the key studies. The profile is not intended to be an exhaustive document; however, more comprehensive sources of specialty information are referenced. CAS# 7439-92-1
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
