A cytochemical study of the blood of the rainbow lizard (Agama agama).

Smears of peripheral blood from the common rainbow lizard (Agama agama) were examined for the distribution and localization of lipid, glycogen, acid phosphatase, alkaline phosphatase and peroxidase, using a variety of staining techniques. While erythrocytes were strongly reactive with the peroxidase test, granulocytes and monocytes were only weakly or moderately active. Lipid and glycogen, as well as acid and alkaline phosphatase, were found in granulocytes and monocytes. Some lymphocytes showed weak acid phosphatase and moderate PAS activities. A small population of 'mononuclear' cells was noted which were not reactive to any of the histochemical tests adopted.
