  • Title: [Physical factors of the work environment. Changes in the aorta in experimental exposure to noise and atherogenic diet].

    Journal: Probl Khig; 1984; 9():29-35. PubMed ID: 6483825.
    Abstract:
    An experimental study was carried out on the effect of noise with intensity 85 and 95 dB on the changes in the vascular walls of albino rats of an atherogenic diet (cholic acid, cholesterol and vitamin D2) in the course of 30 daws. The single effect of noise did not induce essential deviations in aortic metabolism and structure. The atherogenic diet caused segmental increase of intracellular substance, disorientation of tissue elements, destruction of smooth muscular cells, accompanied by activation of anaerobic oxidation processes, increase of the quantity of collagenous proteins with reduced globular and elastin proteins content. The noise, with an intensity of 95 dB intensifies the alterations in the vascular wall to the origination of medionecroses.
