Comparative Study of Rhodanese Activity in Some Tissues of a Day old and 12 Weeks old Domestic Fowl (Gallus do111estic US)

Abstract

Rhodanese activity was assayed in the liver, kidney and heart of a day old and 12 weeks old domestic fowl (G. domesticus'[, The activity in these tissues differed significantly (P < 0.05). The order of activity of the enzyme was liver) heart) kidney. Rhodanese activity in the liver and heart of a day old domestic fowl was about twice the activity in the liver and heart respectively of 12 weeks old domestic fowl. Kidney ofa day old and 12 weeks old domestic fowl showed no significant difference (P < 0.05) in rhodanese activity. The higher rhodanese activity in the liver of domestic fowl may not be unconnected to the role of this organ in cyanide detoxification. The higher activity in tissues of a day old compared to the 12 weeks old domestic fowl may suggest other possible role of rhodanese in these tissues, in addition to cyanide detoxification.
