Suboptimal dietary zinc (Zn(2+)) intake is increasingly appreciated as an important public health issue. Zn(2+) is an essential mineral, and infants are particularly vulnerable to Zn(2+) deficiency, as they require large amounts of Zn(2+) for their normal growth and development. Although term infants are born with an important hepatic Zn(2+) storage,(More)
The radioprotector zinc aspartate did not inhibit the radiotherapeutic effect of gamma rays on human tumours grown as xenografts in immunosuppressed mice, while aminothiol radioprotectors afforded a slight inhibition. On the other hand, zinc aspartate significantly reduced the fall in the haematocrit and numbers of thrombocytes, erythrocytes and leucocytes(More)
The organic zinc salts zinc aspartate, zinc histidine, zinc orotate and zinc acetate reduced the fall of the haematocrit, thrombocytes, erythrocytes and leucocytes in irradiated mice. In general, zinc aspartate was more effective than the other organic zinc salts. Protection of the haematocrit and thrombocytes by small doses of the aminothiol radioprotector(More)
Survival of mice after lethal doses of a lyophilizate fromAmanita phalloides (‘death cap’) was markedly increased by pretreatment with single doses of kutkin, a mixture of iridoid glycosides picroside I and kutkoside isolated from the roots ofPicrorhiza kurroa. The protective effect of kutkin was comparable to that of silibinin. The curative efficacy of(More)
A human tumor xenograft model using pharmacologically immunosuppressed mice was assessed for its suitability to test preclinically the sensitivity of colorectal carcinomas, bone sarcomas and melanomas against anticancer agents. Besides ionizing radiation, 14 cytotoxic drugs including 5-fluorouracil (5-FU), dimethylmyleran (DMM), cytosine arabinoside,(More)
BACKGROUND Morbidity and mortality in T1DM depend on metabolic control, which is assessed by HbA1c measurements every 3-4 months. Patients' self-perception of glycemic control depends on daily blood glucose monitoring. Little is known about the congruence of patients' and professionals' perception of metabolic control in T1DM. OBJECTIVE To assess the(More)
