To identify cells and analyze proliferative activity of hematopoietic tissue, black scorpionfish head kidney and spleen cells were characterized by light microscopy and flow cytometry. Hematopoiesis of black scorpionfish head kidney was formed by the following series: erythropoietic, granulopoietic, lymphopoietic, and thrombopoietic. Flow cytometric analysis allowed dividing blood cells in hematopoietic organs into subpopulations differing by size, granularity, and proliferative activity.

A series of carotenoids with 19- or 19'-hexanoyloxy moieties, 19'-hexanoyloxyfucoxanthin (1), 19'-hexanoyloxyfucoxanthinol (2), 19'-hexanoyloxyhalocynthiaxanthin (3), 19-hexanoyloxycrassostreaxanthin A (4), 19-hexanoyloxymytiloxanthin (5), and 19-hexanoyloxyallenicmytiloxanthin (6) were isolated from the edible part of the sea mussel, Mytilus galloprovincialis, grown in the Black Sea, Ukraine. Among them, 3, 4, and 6 were new compounds. These structures were charcterized by UV-vis, fast atom bombardment mass spectrometry, circular dichroism, and (1)H NMR spectroscopic data.
