Uklanjanje kolodijskog ugljika iz krvi tilapije (Oreochromis niloticus L.).

This study reports the rate of clearance of colloidal carbon from the blood of Tilapia (Oreochromis niloticus L.), over a period of 250 minutes following intravenous injection of five different doses. Thirty Tilapias (125-170g) were divided into 6 equal groups (A-F). Carbon doses of 4 mg, 8 mg, 16 mg, 32 mg and 48 mg were injected to fish in 0.15 ml distilled water. The control, group F, was injected with 0.15 ml distilled water. The clearance of carbon was observed to be regular and progressive for all doses. Carbon particles uptake by monocytes was noticed 5 minutes post-injection. However, the phagocytic index was inversely proportional to the dose of carbon injected. The significance of clearance of carbon and other particulate antigens is discussed.
