Effects of selected groundwater chemical traits on a salt marsh community
Electrical conductivity, exchangeable sodium ratio and water depth have negative impacts, whereas soil organic matter concentration has a positive impact on Black Sea salt marsh vegetation. The most saline soils were characterized by Salicornia prostrata vegetation and associated with exchangeable sodium ratio. Alhagi pseudalhagi and Tamarix smrynensis populations were associated with water depth, while Juncus littoralis, Ammophila arenaria and E. paralias were associated with soil organic matter. Euphorbia paralias, Ammophila arenaria and Iris orientalis were associated with acidity.
A one-day-old female Holstein calf was presented with subcutaneous masses spread over the whole body. Macroscopically, the masses were firm in touch, greyish-white in colour, 0.5-2 cm in diameter range. Histopathological examination confirmed the cutaneous Kaposiform hemangioendothelioma (KHE). Microscopic examination of the tumor revealed sheets of spindled endothelial cells forming vascular slits. Immunohistochemically, the tumor cells and capillaries gave strongly positive reaction for CD31 while vimentin, alpha smooth muscle actin and cytokeratin AE1/AE3 were negative. In this case, macroscopical, detailed histhopathological and immunohistochemical findings of congenital KHE reported firstly in a newborn calf.
