Five-week-old male Crj:CD (SD) rats were treated with excess sodium chloride after abdominal X-irradiation. The gastric regions of the rats were irradiated with a total dose of 20 Gy given in two equal fractions separated by 3 days. After X-irradiation, animals were fed a diet containing 10% sodium chloride. Red blood cell anemia appeared 22 weeks after the last irradiation. By gross observation, the mesenteric arteries became reddish in color, and bead- or lead pipe-like nodular thickenings were present. Microscopically, these nodularly thickened mesenteric arteries showed fibrinoid necrosis with massive inflammatory infiltration including eosinophils and neutrophils. In more advanced lesions, elastica interna and externa and medial smooth muscle cells disappeared completely and were replaced by granulation tissue. In old lesions, arterial walls were markedly thickened with fibrous or fibromuscular tissue. These findings were quite similar to those of the human periarteritis nodosa. These arterial lesions could not be found in the rats with X-irradiation only, sodium chloride only, or in nontreated animals. This study demonstrates X-ray-induced, NaCl-promoted periarteritis nodosa-like lesions in rats. 相似文献
