Cone photoreceptors in teleost fish are organized in precise, crystalline arrays in the epithelial plane of the retina. In zebrafish, four distinct morphological/spectral cone types occupy specific, invariant positions within a regular lattice. The cone lattice is aligned orthogonal and parallel to circumference of the retinal hemisphere: it emerges as(More)
Monovalent and bivalent Fab-fragments of normal human or rabbit gamma-globulin suppressed blasttransformation of human lymphocytes induced by phytohemagglutinin and concanavalin A. Peptic F(ab)2-fragments from highly-purified rabbit anti-DNP antibody displayed suppressing activity similar to that of the fragments of normal gamma-globulin. Fab-fragments(More)
A study was made of the sensitivity to prednisolone (PS) of peripheral blood mononuclear cells (MS) of patients with systemic lupus erythematosus (SLE) with renal lesion showing resistance to glucocorticoids (GC). It was shown that in most of the patients (60%) MC were poorly inhibited by PS whereas the rest of the patients (40%) demonstrated in vitro(More)
In the present study the fine structure of rat Leydig cells was examined by electron microscopy. Oxytocin and dexamethasone induced changes in the activities of 3beta hydroxysteroid dehydrogenase, NADH2 cytochrome-C-reductase and glucose-6-phosphate dehydrogenase in these cells were studied in an in vivo experiment. Two groups of male Wistar rats were used(More)
Thermo- and acid-stable serine proteases inhibitor from the rabbit blood serum (TASPI) was shown to inhibit the human peripheral blood lymphocytes transformation stimulated by phytohemagglutinin (PHA) or concanavalin A. The extent of inhibition depended on the concentration of the preparation and its specific activity. The maximal inhibition of lymphocytes(More)
Discrete characters of the occlusal surface (additional cusps) have been studied to elaborate a new approach to the identification of the Ground Squirrel species Spermophilus odessanus, S. suslicus, S. pygmaeus, S. citellus, and S. xanthoprymnus. Data on the presence/absence of the additional cusps have been represented as star plots and, in addition, have(More)
