Copper deficiency can cause cardiovascular lesions in experimental animals. Previous experiments have shown that the biochemical and itDrphologic lesions induced by deprivation of dietary copper can be suppressed by feeding diets containing starch or can be magnified by a high sucrose diet. In a recent study it was found that the more severe signs of copper deficiency in rats fed sucrose as compared to starch were due to the fructose moiety of sucrose. Although fructose as compared to starch markedly enhanced the symptoms of copper deficiency, the possibility that an effect of dietary carbohydrates due to the nature of the simple carbohydrate (fructose vs glucose) cannot be excluded. The present study was designed to determine if the severity of copper deficiency in rats fed sucrose as compared to starch is due to the glucose as well as the fructose moiety of sucrose. This portion of the study assessed the morphologic changes in aortas of seventy weanling male rats who were fed, for 9 weeks, copper deficient or copper supplemented diets containing either 62% starch, fructose or glucose. The starch-fed copper supplemented group served as the most normal controls. Rats were sacrificed after 9 weeks of dietary treatments. Copper deficiency was verified by reduced serum ceruloplasmin activity and serum and hepatic copper concentration.

We have synthesized and tested for their antiinflammatory activity a new series of 3-aryl-4,5-dihydro-4-isoxazoleacetic acids (IVa-IVg). Preliminary pharmacological results seem to indicate the 3-phenyl derivative IVa as the most interesting compound. In fact, when tested against carrageenin edema in Wistar rats, it shows antiinflammatory activity comparable to that of naproxene, taken as reference drug, though of shorter duration. All the substituted phenyl derivatives were less active (IVd-IVf) or inactive (IVb, IVc, IVg).

Excessive intake of zinc is a known but often forgotten cause of copper deficiency, and its consequences in the context of end-stage renal disease (ESRD) are not widely discussed. Zinc-induced copper deficiency (ZICD) can result in erythropoietin (EPO)-resistant anemia and may not be considered as a possible etiology when conducting the work-up. We present a case wherein an ESRD patient had been receiving excess zinc for several months and subsequently experienced EPO-resistant anemia. Our patient’s GI work-up was negative, and increased doses of iron and EPO-stimulating agent were ineffective. She underwent a bone marrow biopsy and more serological testing. She was ultimately diagnosed with ZICD, and cessation of her zinc supplement and initiation of copper replacement proved effective in restoring EPO responsiveness. Awareness of ZICD as a possible factor in EPO-resistant anemia could lead to an expedited diagnosis and avoid an unnecessary and extensive work-up.
