Abnormalities in carbohydrate metabolism and the insulin resistance status have been associated with hypertension. We have previously described alterations in the sodium-coupled sugar absorption in an experimental model of hypertension; in the presen

Mammalian radioimmunoassay may be used for the measurement of fish glucagon, but the antibody must be chosen carefully. Of the antibodies analysed, 30K (Unger et al., J. clin. Invest. 41, 628–689), K5563 (Novo), 299-221R (Cambridge), and A31 (Milab

1. 1. Blood parameters determining oxygen capacity and oxygen affinity were measured in brown trout at different times of the year. 2. 2. Haematological data indicate a slight decrease in blood oxygen capacity during the warm seasons. 3. Oxygen affin

1. 1. Insulin, glucagon and plasma glucose levels were studied during the post-feeding period in juvenile brown trout (Salmo trutta fario). Three experiments were performed, in June, July and October, with animals weighing 60.0 ± 0.9 g, 102 ± 2.6 g

Iron (Fe) absorption by three segments (duodenum, jejunum, and ileum) of the small intestine of chickens was studied by a perfusion technique in vivo in closed circuit using 59Fe Cl3 and was related to the histological characteristics of each segment

1. Pyrenean brown trout juveniles (Salmo trutta fario) were fasted for 50 days in late winter (experiment 1) and summer (experiment 2). Plasma insulin, glucagon and glucose and some metabolites in plasma and in tissues were analysed. 2. Glucagon incr

1. The structure of the chicken caecal epithelium has been investigated at macroscopic and microscopic levels (scanning and transmission electron microscopy). 2. Morphological data distinguish three regions in the caecum: proximal, with well develope

We have studied some hematological parameters and iron and ferritin iron contents in different organs of New Hampshire chickens at the ages of 4, 8, 13, and 18 wk for both sexes, as well as 24 wk for laying hens, in order to study the variations with

Brush border membrane vesicles (BBMV) enriched in sucrase, maltase and alkaline phosphatase, and impoverished in Na(+)-K(+)-ATPase, were isolated from proximal and distal intestine of the gilthead sea bream (Sparus aurata) by a MgCl(2) precipitation

In mammals, D-fructose transport takes place across the brush-border membrane of the small intestine through GLUT5, a member of the facilitative glucose transporter family. In the present paper, we describe and characterize for the first time the api
