Journal ArticleDOI
Specific endocrine tissue marker defined by a monoclonal antibody.
Ricardo V. Lloyd,Barry S. Wilson +1 more
TL;DR: One of two mouse monoclonal antibodies (LK2H10) produced by hybridoma technology against a human endocrine tumor demonstrated specific immunoreactivity for 69 normal and neoplastic endocrine and tissues known to contain secretory granules.
Journal ArticleDOI
Preoperative treatment of acromegaly with long-acting somatostatin analog SMS 201-995: shrinkage of invasive pituitary macroadenomas and improved surgical remission rate.
Ariel L. Barkan,Ricardo V. Lloyd,William F. Chandler,Malcolm K. Hatfield,Stephen S. Gebarski,Robert P. Kelch,Inese Z. Beitins +6 more
TL;DR: Preoperative administration of SMS 201-995 consistently induced shrinkage of GH-producing pituitary tumors, and the apparent remission rate was high in the treated patients.
Journal Article
An analysis of "ablation of thyroid remnants" with I-131 in 511 patients from 1947-1984: experience at University of Michigan.
William H. Beierwaltes,Roya Rabbani,Carl Dmuchowski,Ricardo V. Lloyd,Patti Eyre,Shirley Mallette +5 more
TL;DR: Of 267 patients with radioiodine uptake confined to the thyroid bed, 233 had ablation from the first dose of I-131 ranging from 100 to greater than 200 mCi, with the higher the percent uptake, the more difficult it was to achieve ablation.
Journal ArticleDOI
Chromogranin: A newly recognized marker for endocrine cells of the human gastrointestinal tract
TL;DR: Investigation of immunocytochemistry for chromogranin found it to provide a means for demonstrating all gastrointestinal mucosal endocrine cells identifiable by the methods described in this study.
Journal ArticleDOI
MEN I pancreas: A histological and immunohistochemical study
Norman W. Thompson,Ricardo V. Lloyd,Ronald H. Nishiyama,Aaron I. Vinik,William E. Strodel,Maria Allo,Frederic E. Eckhauser,Gary Talpos,Tim Mervak +8 more
TL;DR: All MEN I patients with pancreatic neoplasms have diffuse islet cell involvement consisting of nesidioblastosis, micro- and macronodular hyperplasia, and some patients are at risk to develop new tumors, but complete excision of grossly apparent tumors may result in long-term control of the endocrinopathy present.
