Exposure of cultured clone A human colon tumor cells to 25 to 75 microM of NSC 368390 [6-fluoro-2-(2'-fluoro-1,1'-biphenyl-4-yl)-3-methyl-4-quinolinecarbox yli c acid sodium salt, DuP 785] for 48 to 72 h resulted in a 99.9% cell kill as determined by clonogenic assay. Cells exposed to NSC 368390 became depleted in intracellular pools of uridine(More)
An in vitro tetrazolium dye (MTT) reduction technique was modified and evaluated for use in the large-scale screening of anticancer compounds by examining the activity of ten clinically used drugs against 16 different human and murine cell populations. Cell populations included colon and mammary adenocarcinomas, melanomas, leukemias, and freshly isolated(More)
The Oral Glucose Tolerance Test is a commonly used test for diagnosis of Impaired Glucose Tolerance and Type 2 Diabetes Mellitus. In practice, there are two standard sample time intervals: deltat=60 min and deltat=30 min and two standard test time durations: 120 and 180 min. However, for an accurate description of blood glucose concentration dynamics, this(More)
The number of mast cells in the stroma of human squamous cell cancer -- keratoblastif cum, paraepidermale and male diffusa was 2-30 times lower than in the stroma o-normal squamous epithelium or in the connective tissue distant from neoplastic epithelium. These differences are statistically highly significant. The reduction of mast cel, number apparently(More)
A simian virus 40 (SV40)-transformed line of human parapharyngeal cells (SV-TGo) was cultured in semisolid agar to determine its ability to grow in the absence of an anchoring substratum and to evaluate any phenotypic changes that might have resulted during the isolation of sublines specifically selected for anchorage independence. After 2--3 weeks and(More)
