The negative-feedback actions of corticosterone (CORT) depend on both phasic and tonic CORT secretion patterns to regulate hypothalamic-pituitary-adrenal (HPA) axis activity. How these two different CORT secretion pattens influence specific intracellular signal transduction pathway activity within the cellular elements of the HPA axis has not been(More)
Fixed and unfixed smears of bovine spermatozoa were stained for esterase activity at pH 6.1–6.2 using 1-naphthyl acetate as substrate and hexazonium pararosaniline as coupler. Best results were obtained with unfixed smears prepared from suspensions of spermatozoa washed free of seminal plasma. The most intense staining was obtained when smears were(More)
This paper describes methods for the cytochemical demonstration of non-specific esterase and acid phosphatase activities in spermatozoa of the mouse. The acetate and phosphate esters of 1-naphthol were used as substrates, and hexazonium pararosanilin was used as coupler in both techniques. Specificity was assured by the use of appropriate positive and(More)
BACKGROUND 2'-4' Dinitrofluorobenzene (DNFB) induced contact hypersensitivity is an established model of contact sensitivity and leukocyte migration. Platelet Endothelial Cell Adhesion Molecule-1 (PECAM-1) deficient mice were used to examine the role of PECAM-1 in the migration capacity of several different leukocyte populations after primary and secondary(More)
