In the present study, the effect of selective glucocorticoid deficiency on renal water excretion was investigated in conscious, trained, adrenalectomized dogs. The animals were studied before and after a water load while on replacement therapy of desoxycorticosterone acetate, 5 mg/day, and dexamethasone, 0.8 mg/day (group I), and while off dexamethasone for 5-9 days (group II). Before the water...

Introduction In India, both Iodine Deficiency Disorders (IDD) and fluorosis (due to consumption of excess fluoride), are the two most prevalent endemic diseases which coexist in certain regions in the country. Though goiter—an enlarged thyroid gland—is commonly recognized as a visible sign of iodine deficiency, the health effects of iodine deficiency reach far beyond those of goiter, and the si...

Using a pure, bacteria-free culture of Nostoc muscorum as a bioassay test organism, it was found that the water of Bass Lake, Livingston Co., Michigan, had a severe phosphate deficiency and less severe deficiencies of K, Fe, Mn, and Mg. Emission spectrographic analyses showed that the concretions had Ca as the principal constituent, Mg as the major impurity, and Fe, Si, Mn, Al, and Sr as minor ...

Biotin is one of the water-soluble vitamins which plays an important role as a covalently bound coenzyme for carboxylases in fatty acid synthesis, gluconeogenesis and branched-chain amino acids (BCAA) metabolism in mammals. This vitamin is widely distributed in various foods and produced in intestinal microflora. Biotin deficiency is rare in general dietary habits. However, biotin deficiency In...

BACKGROUND This study was performed to demonstrate the widespread distribution and severity of selenium (Se) deficiency in sheep flocks and to evaluate the impact of influencing factors. In 150 flocks, ten serum samples of adult ewes were analysed for Se concentration. The farmers were interviewed concerning flock size, provision of mineral supplement, predominant form of husbandry (stationary ...

Radial water (J(V)) and abscisic acid (ABA) flows (J(ABA)) through maize root seedlings have been investigated under different conditions of nutrient deficiency. Whereas J(V) was reduced under nitrogen deficiency, potassium deficiency stimulated J(V). A substantial increase of J(ABA) was observed in roots kept under potassium deficiency. The observed changes of J(V) might have resulted from cha...

1. Simultaneous measurements of exchangeable Na+, exchangeable K+ , extracellular fluid volume and total body water, with 24Na, 43K, "Br and 3Hz0, were carried out in patients with adrenocortical insufficiency due to pituitary ablation performed 1-3 months previously. 2. The first group of five patients was studied before and after withdrawal of maintenance prednisone (2.5 mg three times daily,...

this experiment was conducted to increase the resistance of tiger barb (capoeta tetrazona ) against environmental stress by feeding brackish water gammarus sp. powder as supplementary diet in three levels (25%, 50% and 75%) and three replicates pe group compared to control group for 60 days. fishes was fed with 4 diet treatment containea of: 100% artificial diet (control group), 25% brakish wat...

The aim of our experiments was to investigate whether nutrient deficiency or toxicity is the cause for growth inhibition of wheat and barley in waterlogged soils. Experiments using two soils (top and subsoil) differing largely in various characteristics revealed a growth inhibition of wheat and barley in the case of subsoil due to water logging, without Fe or Mn toxicity. Water culture experime...
