Synthetic detergents are used in large quantities as household and industrial cleaners. Because of the common practice of leaving dishes washed in detergent solutions to dry without rinsing these compounds are ingested. We have calculated that an adult takes in about 1 mg/kg detergent a day and babies can be administered between seven and 10 mg/kg a day. Rats were fed a dose of 100 mg/kg a day in a pilot experiment and gross abnormalities were found in the gastrointestinal tract, the most striking being subtotal villous atrophy of the small bowel mucosa and glandular atrophy in the colon. These changes were not reversible 12 weeks after cessation of detergent administration. 相似文献

The effect of aging on the ability of the liver to activate chemical procarcinogens was studied using 12-, 18-, and 27-month-old male Fischer F344 rats. The cytochrome P-450 content of the S9 and microsomal fractions of the liver decreased approximately 30% between 12 and 18 months of age. The structural conformation of cytochrome P-450 in microsomes from 12-, 18-, and 27-month-old rats was studied using electron-spin resonance spectroscopy. An age-related decrease in the amount of cytochrome P-450 ferric iron in the liver microsomes was observed. The conversion of the chemical procarcinogen aflatoxin B1 to mutagenic compounds by the S9 and microsomal fractions of liver was measured using the Salmonella typhimurium bioassay. A 40-50% decrease in the metabolic activation of aflatoxin B1 was observed between 12 and 18 months of age. However, the activation of aflatoxin B1 did not change after 18 months of age. The age-related decrease in the activation of aflatoxin B1 by liver appears to be due to a decrease in the metabolic activity of the mixed-function oxidase system. 相似文献

The autotransplantation of liver into the subcutaneous tissues in rats and hamsters resulted in the development of periodic acid Schiffs staining positive granules, which were resistant to diastase digestion. These granules were confirmed as alpha-1-antitrypsin by immunohistochemical staining. The appearance of the alpha-1-antitrypsin containing hepatic granules is comparable to those seen in the liver of humans with genetically determined alpha-1-antitrypsin deficiency. 相似文献

Thoracic aortic to infrainguinal arterial bypasses are rare in the literature, even more so when the outflow is the popliteal artery bilaterally. The case of a patient presenting with critical limb ischemia, chronic infrarenal aortic occlusion, and recurrent thrombosis of a unilateral axillobifemoral graft managed with thoracoretroperitoneal bitransobturator bipopliteal bypass is presented. The patient's vascular history was significant for multiple previous groin procedures for thrombectomy of her axillobifemoral graft, aortomesenteric bypass, redo aortomesenteric bypass for graft thrombosis, and multiple bowel resection procedures for acute mesenteric ischemia. The thoracic aorta and popliteal arteries were selected as sites for proximal and distal anastomoses, respectively, given anticipated difficulty in exposing the supraceliac aorta and femoral arteries. The technique of this operative approach is discussed. 相似文献
