Stress simulation: ACTH and zinc effect on trace metals in liver and spleen

Abstract

Effect of ACTH and zinc acetate subcutaneous injection on the trace metals in liver and spleen was investigated in male Wistar rats. Iron, copper, zinc and manganese in liver, and iron, copper and zinc in spleen were analyzed by AAS method. The iron, copper and zinc levels in liver, and iron levels in spleen showed a significant decrease at 1-1 h 30 min after administration of 30 UI of ACTH but values returned to normality or showed slightly higher levels at 4 h 30 min-7 h 45 min. Zinc acetate injection only elicited an increase in liver and spleen zinc levels. Results are discussed in relation with results given in previous papers.
