  • Title: Effect of noise on the development of induced sclerotic processes in the rat aorta.
    Author: Antov G, Ivanovich E, Kazakova B, Goranova L.
    Journal: Cor Vasa; 1985; 27(5):390-5. PubMed ID: 4075803.
    Abstract:
    The authors studied the effect of 95 and 85 dB noise on the aortic wall of white rats fed for a period of 6 weeks an atherogenic diet (cholesterol + cholic acid + vitamin D2). Noise alone did not cause significant changes in the metabolism and structure of the aorta. The atherogenic diet alone caused segmental enlargement of the intercellular substance, disorganization of tissue elements, and destruction of smooth-muscle cells with marked activation of anaerobic processes, an increase in collagen content and a decrease in globular proteins and elastin. Simultaneous action of noise and of the atherogenic diet produced more pronounced biochemical and morphological alterations in the aortic wall than the diet alone. Noise not only contributes to the development of sclerotic processes but causes also complicated lesions of the aortic wall.
