Microscopic Vision for a Therapeutic Effect of Carnitine and Arginine Against Cadmium Toxicity in the Histological Structure of Rat Lung

Abstract

The study is conducted to investigate the therapeutic effect of L-carnitine and L-arginine on the histological structure of the lung in rats treated with cadmium chloride. The study included 20 male rats subjected to the necessary laboratory conditions throughout the experiment. The results show the occurrence of many tissue lesions in the lung, represented by the degeneration of the lining epithelial cells and the shedding of many of these cells in the lumen of the bronchioles. In addition, there is necrosis of the interstitial tissue between the alveoli, with the presence of clumps of red blood cells in the cavities of some blood vessels in the group treated with cadmium chloride, the group treated with cadmium chloride, and L-carnitine, and the group treated with cadmium chloride and L-arginine.
