We describe a subject who developed asthma symptoms 2 yrs after being employed at a plant where metals were galvanized in heated zinc. The subject was not atopic. Baseline spirometry was normal three months after he left work but there was mild bronchial hyperresponsiveness to methacholine. Monitoring of forced expiratory volume in one second (FEV1) during a day at work showed a maximum fall in...

This study was undertaken to determine the effects of zinc sulphate on the weights of pregnant rats, on the food and water consumption during gestation, litters weight at birth, the number of litters at birth and the accumulation of zinc in selected organs of the litters. Zinc sulphate in the dose of 1 mg/l and 20 mg/l drinking water was administered to both pregnant and non-pregnant for the pe...

Zinc transporter (ZnT1) mRNA is differentially expressed in vivo, in weaned pig tissues, and in vitro, in response to additions of zinc sulphate or antibiotics. Summary Preliminary experiments were carried out to evaluate in vivo expression of zinc transporter (ZnT) 1 mRNA in a panel of tissues obtained from weaned pigs and to evaluate in vitro changes in ZnT1 mRNA in a porcine jejunal epithe-l...

INTRODUCTION The fitness of water supplies for public consumption may be assured by minimal treatment where high purity sources are available. Aluminium sulphate is used in the coagulation process forming a floc which acts as a filter for the removal of finer particles. The presence of a high concentration of aluminium sulphate in the water supply lowers the pH of the water and may result in th...

After initial promotion of copper excretion with D-penicillamine, the effect of oral zinc sulphate (3 X 150 mg/day, loading dose; 3 X 100 mg/day, maintenance dose) in two children with clinically stable Wilson's disease was evaluated after completion of three years' treatment. The course, judged by clinical, biochemical, and histological parameters was satisfactory in both. The urinary copper c...
