In vitro destruction of cancerous cells by rat peritoneal macrophages in the presence of endotoxins

Rat resident peritoneal macrophages are able to kill DHD K12 TS cancer cells in the presence of endotoxin without previous activation. This effect is inhibited by polymyxin B or hydrocortisone. This effect is not observed when macrophages or cancer cells are preincubated with endotoxin.

The distribution of scleractinian corals in the Bay of Biscay, NE Atlantic

Studies on the distribution of scleractinian corals in the Bay of Biscay were relatively numerous during the nineteenth and the first half of the twentieth century. Yet, recent reports are scattered, sometimes unpublished, and therefore knowledge about the current coral occurrence in the area is limited. This study aims at compiling the available historical and more recently collected information on the occurrence of scleractinian corals in the Bay of Biscay. Data from two recent cruises are included and compared with previous explored coral sites from as early as 1830 up to 1995. A database of 347 records including 34 described species of scleractinians highlights that the slope of the Bay of Biscay is an important habitat for scleractinians. This could be expected due to the high topographic relief providing the necessary hard substrate and accelerated bottom current flow that corals require. Further exploration of the occurrence and ecology of corals in the area is recommended to support the conservation of cold-water coral reefs along the European margin.
