Effect of a Trichinella spiralis infection on the distribution of mast cell precursors in tissues of thymus-bearing and non-thymus-bearing (nude) mice determined by an in vitro assay. Open
The frequency of precursor cells capable of giving rise to cells with characteristics of mucosal mast cells in tissues from thymus-bearing and non-thymus-bearing (nude) mice orally infected with Trichinella spiralis was determined with an …
DNA and nuclear protein measurement in columnar epithelial cells of human endometrium Open
Propidium iodide DNA flow cytometry, Feulgen‐DNA, and nuclear light green protein scanning cytometry were performed in columnar epithelial cells of normal, nonmalignant human endometrium and endometrial adenocarcinomas. Columnar cells were…
DNA and nuclear protein measurement in isolated nuclei of human endometrium Open
Feulgen‐DNA and nuclear light green‐protein measurements have been performed in isolated nuclei of normal (nonmalignant) and malignant human endometrial homogenates. The DNA content of the GO/G1 fraction of malignant endometrium showed muc…
In vitro studies on mast cell proliferation in N. brasiliensis infection. Open
We have previously shown that mast cells with the morphological and biochemical properties of mucosal mast cells (MMC) proliferate and mature in rat bone marrow cultures stimulated with factors from antigen or mitogen-activated T lymphocyt…
The role of exogenous electron carriers in NAD(P)-dependent dehydrogenase cytochemistry studied in vitro and with a model system of polyacrylamide films. Open
The applicability of phenazine methosulfate, 1-methoxyphenazine methosulfate, menadione, and meldola blue as exogenous electron carriers for the cytochemical staining of nicotinamide adenine dinucleotide (phosphate) (NAD(P))-dependent dehy…
Fundamental aspects of the interaction of propidium diiodide with nuclei acids studied in a model system of polyacrylamide films. Open
Qualitative and quantitative aspects of the fluorescent propidium diiodide (PI) staining method have been investigated with model films of polyacrylamide gel incorporated with DNA, RNA, and other macromolecular compounds. PI was found to b…
