On the failure to detect haemosiderin in the melano-macrophages of dogfishScyliorhinus canicula (L.) after prolonged starvation

Short Communications Biochemistry


When teleost fish are starved, the number of melano-macrophages increases markedly within the spleen and kidney. This increased pigment deposition is almost certainly a consequence of catabolic tissue breakdown. One of the pigments, haemosiderin, resulting from the breakdown of haemoglobin of red blood cells, accumulates almost exclusively in the melano-macrophages of the spleen but not within the kidney melano-macrophages. In contrast when elasmobranchs, as exemplified by the dogfishScyliorhinus canicula are starved, melano-macrophages accumulated predominantly in the liver and to a lesser extent in the spleen. However no haemosiderin deposits could be detected in the melano-macrophages of either of these two organs. This is suggestive of functional differences between the melanomacrophages of elasmobranchs and teleosts.
