Histopathological examinations were performed upon groups of male Fischer rats killed at intervals from 1 h to 18 weeks after unilateral intrarenal (ir) injection of nickel subsulfide (2.5 or 5 mg of Ni3S2/rat). Consistent with previous findings, erythroid hyperplasia of bone marrow and spleen occurred from 2 to 18 weeks after Ni3S2-treatment, resulting in pronounced erythrocytosis. Hitherto unreported effects of Ni3S2-treatment include: (a) marked glomerulomegaly and hyperplasia of mesangial cells in both kidneys; (b) hyperplasia of submandibular salivary glands, and (c) widespread arteriosclerotic lesions. The present study suggests that mesangial cells of renal glomeruli produce erythropoietin. Discovery that ir injection of Ni3S2 induces arteriosclerotic lesions in rats furnishes a new experimental model to investigate the pathogenesis of arteriosclerosis.

D001161 Arteriosclerosis Thickening and loss of elasticity of the walls of ARTERIES of all sizes. There are many forms classified by the types of lesions and arteries involved, such as ATHEROSCLEROSIS with fatty lesions in the ARTERIAL INTIMA of medium and large muscular arteries. Arterioscleroses
D013363 Submandibular Gland One of two salivary glands in the neck, located in the space bound by the two bellies of the digastric muscle and the angle of the mandible. It discharges through the submandibular duct. The secretory units are predominantly serous although a few mucous alveoli, some with serous demilunes, occur.
