Toxicological and Biological Activities of the Acid Secretion of Berthellina citrina (Heterobranchia, Pleurobranchidae) from the Red Sea
_Berthellina citrina _is a pleurobranchid opisthobranch characterized by its skin acid-secretion that contains sulphate and chloride ions with traces of organic matter. To identify defensive potential and bioactivity, we tested this secretion for the first time against _Artemia salina_, different strains of microorganisms, human RBCs and human cancer cell lines. It showed lethality to _A. salina _with LC50 values 83.86 ... إقراء المزيد
