In order to examine macrophages phagocytosing polymorphonuclear leucocytes (PMNs) in detail, we established a new method, whereby a large number of PMN-phagocytosing macrophages (PPMs) were easily induced. PPMs were harvested from the peritoneal cavity after thioglycollate medium, oyster glycogen, phytohaemagglutinin (PHA), L. monocytogenes or S. aureus had(More)
Interphotoreceptor retinoid-binding protein (IRBP), a glycoprotein specific for the retina and pineal gland, induces inflammatory changes in these two organs in immunized animals. We report here on the identification of an immunodominant determinant of bovine IRBP that is highly immunogenic and immunopathogenic in the Lewis rat. The peptide, which comprises(More)
Insulin was employed as a stimulant in our continuing investigations of the molecular mechanisms involved in the coordinate control of cellular metabolism and growth. Incubation of chicken embryo fibroblasts for 16 hours in media containing 0-0.1 U insulin/ml resulted in a 17-fold increase in the rate of 3H-thymidine incorporation into DNA. Concomitantly,(More)
We studied family members of 9 patients with falciform retinal fold, and found a number of cases showing features of familial exudative vitreoretinopathy (FEVR) in the fundi. Retinal fold was also seen in the eye of a cousin of the propositus. Three cases with falciform retinal fold were bilateral and 7 cases were unilateral. Retinal folds were located in(More)
Omission of Ca(2+) from the medium of confluent BALB/c3T3 cells for a period of 17 hr causes a large decrease in the number of cells synthesizing DNA. This effect is reversed by raising the Mg(2+) concentration of the medium to 20 mM. However, if the [Mg(2+)] is greater than 20 mM ("ultra-high" Mg(2+)), there is again a decrease in the number of cells(More)
Decreasing the K+ concentration of the medium from 5 mM to 0.59 mM decreased the K+ content of chick embryo fibroblasts to 22% of control values and increased the Na+ content to 820% of control values. The alteration of monovalent cation content occurred within two hours but had no effect on the rate of DNA synthesis, as measured by 3H-thymidine(More)
