Anti-inflammatory effects of cerebrocrast in a model of rat paw edema and on mononuclear THP-1 cells.

Cerebrocrast (IOS 1.1212; 4-[2-(difluoromethoxy)phenyl]-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylic acid di(2-propoxyethyl) diester) is a novel derivative of 1,4-dihydropyridine, which does not antagonize Ca(2+) influx in neuronal tissues. Since several classical dihydropyridines possess anti-inflammatory properties, we first studied the effects of cerebrocrast in a model of rat paw edema induced by carrageenan.

[The comparative evaluation of spectrophotometric and chemiluminescent detection in an immunoenzyme test of antibodies to the antigens of the bovine leukosis virus].

Comparative evaluation of the sensitivity limit in the detection of antibodies to bovine leukemia virus in the enzyme immunoassay with the use of chemiluminescent and spectrophotometric detection techniques was carried out. In this assay 3-amino-1,4-phthalazinedion was used as chemiluminescent substrate and ortho-phenylenediamine, as chromogenic substrate. The chemiluminescent signal was registered by means of a special luminometer designed at the Institute of Biochemistry (Lithuanian Acad.

Partial characterization of bovine leukemic cell populations.

Peripheral blood lymphocytes (LL) from cows with chronic lymphocytic leukemia (CLL) have been studied using a number of surface markers. Cell populations were obtained by partial enrichment and depletion using Sephadex G-200-anti-F(ab')2 and Sephadex G-200-anti-LL-Ig immunoadsorbent columns. It was shown that cell populations having different markers, i.
