Four hundred forty‐seven women attending a breast clinic because of either suspicious lesions, anxiety about breast cancer, follow‐up after the removal of a benign breast lesion, or a family history of breast cancer had a routine test for percentage of ferritin‐bearing lymphocytes (FBL) in their peripheral blood. Among patients who received surgery following physical examination in the clinic and/or mammography, the test was positive in 40 of the 45 (89%) with Stage I; II carcinoma, 3 of 3 with Stage IV carcinoma, and only in 29 of the 97 (37%) with benign breast disease. The possible reasons for the poorer detection rate in Stage III carcinoma are discussed. The test, however, identified 2 cases of Stage I carcinoma, 1 of breast lymphoma, and 12 with premalignant lesions in those who were found normal on physical examination and mammography. Ferritin‐bearing lymphocyte results tended to become negative after surgical removal of the lesion, and became positive on recurrence of the tumor and appearance of metastases. The detection rate was maximized by combining the FBL test with the clinical modes of detection.
The therapeutic effect of sucralfate on ulcerated gastric and duodenal mucosa is well known. There is, however, almost no information about its activity in colitis. Experimental colitis was produced in rats by rectal instillation of 1 ml of 10 percent acetic acid, and 1.5 ml of a 20 percent suspension of sucralfate was then administered every 12 hours for various lengths of time. Study animals and appropriate controls were killed after 3, 7, 10, or 14 days. The distal colons were studied macroscopically and histologically. Colonic prostaglandin E2 levels were measured in animals killed after 3, 7, 10, or 14 days. The macroscopic score was significantly improved 10 and 14 days after induction of colitis, although the histologic appearance was unchanged. Acetic acid administration increased and sucralfate treatment reduced prostaglandin E2 levels in colitic animals on days 3 and 7, but not later. The present study supports a role for sucralfate in the treatment of colitis, but further studies on the mechanism of its effect and on its clinical activity are indicated.
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.
