The effects of starvation and refeeding of 2-wk-old turkey poults on serum and tissue levels of zinc, copper and iron were investigated. Serum concentrations of zinc and copper declined during 4 d of starvation. Refeeding for 24 h following a period of starvation restored serum copper to levels similar to those in the fed controls but failed to elevate zinc levels. Liver concentrations and tota...

This study was conducted on 25 animals randomly selected from a herd with 40 feedlot cattle, which had poor growth, rough hair coat, and change in the colour of the hair coat. Blood samples were collected from the vena jugularis into the tubes containing Na2EDTA for the determination of plasma copper concentration and blood profile. Feed samples were also tested for copper, zinc, and molybdenum...

Breakthrough in treatment of Alzheimer's disease with a shift from irrational dangerous chelation therapy to rational safe evidence based oral zinc therapy. Evidence based medicine: After synthesizing the best available clinical evidence I conclude that oral zinc therapy is a conscientious choice for treatment of free copper toxicosis in individual patients with Alzheimer's disease. Hypothesis ...

OBJECTIVE To study the serum zinc, selenium, and copper of priest subject who attended the outpatient Department, Priest Hospital Bangkok for a physical check-up, between March and October 2003 MATERIAL AND METHOD The serum zinc, selenium, and copper of 112 priest subjects, 33 healthy and 79 diseased, compared with a control group of 90 males and 119females Thai volunteers. RESULTS Serum co...

LIFSCHITZ, M. D., AND R. I. HENKIN. Circadian variation in copper and zinc in man. J. Appl. Physiol. 31(l): 88-92. 1971.~Copper and zinc metabolism were studied in 10 normal volunteers on a constant regimen consisting of an alternate 4 hourly intake of a liquid diet or distilled water, and a regulated amount of activity. Urine was collected in 4-hr periods and blood samples drawn in the middle ...

This study was to determine the feasibility of using potentiometric stripping analysis (PSA) to measure serum levels of copper, lead, and zinc in elderly subjects with metabolic disorders (hyperglycemia, hypertriglyceridemia, and hypercholesterolemia). Furthermore, we investigated the relationship between serum trace elements and lipid and glucose levels in these patients. There was a strong co...

The toxicity of mixtures of copper, zinc, and diazinon were determined for Ceriodaphnia dubia using 7-d survival and reproduction tests. Fifteen treatments, including combinations of the chemicals at 0, 25, 50, 75, and 100% of their individual median lethal concentrations, adding up to one toxic unit (TU) were tested. The TU was then used to classify each mixture response as additive, greater t...

Background: Seborrheic dermatitis is a common chronic relapsing inflammatory skin disease with unknown etiology. Using zinc and selenium supplements have shown some relieving effects on the symptoms of the disease. The present study was conducted to determine the relationship between serum selenium, zinc, and copper levels with seborrheic dermatitis. Methods: A prospective case-control study wa...

Langmuir–Blodgett (LB) technique has been used to deposit composite multilayers of poly(3-octylthiophene) with cadmium arachidate (POT-CdA), zinc arachidate (POT-ZnA) and copper arachidate (POT-CuA). These composite multilayers were used as precursors to develop the respective semiconducting CdS, ZnS and Cu2S nanoclusters in the POT-arachidic acid (POT-AA) matrix. The formation of sulphide nano...
