1. The influence of single-dose intravenous ouabain on haemodynamics, renal function and vasoactive hormones was investigated in healthy subjects. 2. After ouabain injection there was a significant reduction in minimum and average hourly heart rates. Diastolic blood pressure fell immediately after ouabain, without a significant change in systolic blood pressure. 3. There was no change in renal ...

This study was conducted at the Animal Production Department/ College of Agriculture/ University Diyala from 15/9/2021 to 15/10/2021 investigate effect injecting D-aspartic amino acid in Shami Bucks on some blood biochemical and hormonal characteristics. Twelve's aged between 1.5-2 years, body weight ranged 35-40 kg. The animals were divided into four groups (treatments) with three replicates a...

Bayliss and Starling first coined the term 'hormone' with reference to secretin, a substance they found that was produced by the gut, but released into the blood stream to act at a distance. The intestine is now known as the largest endocrine organ in the body, and it produces numerous hormones with a wide range of functions. These include controlling appetite and energy homeostasis. Obesity is...

Steroid hormones easily cross the blood-brain barrier because of their physicochemical lipid solubility. The hormones act through nuclear receptor-mediated mechanisms and modulate gene transcription. In contrast to their genomic actions, the non-genomic rapid action of steroid hormones, acting via various types of membrane-associated receptors, reveals pharmacological properties that are distin...

The gastrointestinal endocrine cells are essential for life. They regulate the gastrointestinal motility, secretion, visceral sensitivity, absorption, local immune defense, cell proliferation and appetite. These cells act as sensory cells with specialized microvilli that project into the lumen that sense the gut contents (mostly nutrients and/or bacteria byproducts), and respond to luminal stim...

Objectives A multicenter study was organized to explore sources of variation (SVs) reference values (RVs) for 22 major immunochemistry analytes and determine intervals (RIs) the Russian population. Methods According IFCC Committee on Reference Intervals Decision Limits (C-RIDL) protocol, 758 healthy volunteers were recruited in St. Petersburg, Moscow, Yekaterinburg. Serum samples tested five tu...

Background: Each toxic agent results in unique presentations, depending on what neurophysiological changes occur following exposure. Scientific understanding of lead toxicity in the organ systems and at low levels of exposure continues to evolve. However, effects of lead poisoning on the thyroid gland function are controversial. In this descriptive study, changes in thyroid hormones in patients...

Nc ORMAL reproduction and lactation in domestic animals are regulated by hormones, a group of chemical materials that are secreted by the ductless or endocrine glands directly into the blood stream. The blood carries these chemical messengers to the parts of the body where they produce their effects. Of the endocrine glands, the pituitary is the most important. In the cow it is about the size o...

1. We studied cardiovascular variability, baroreflex and blood volume regulating hormones to determine the relative roles of autonomic regulation and hormones during blood donation.2. The sympathetic response was studied by measuring the R-R interval and systolic blood pressure variability using coarse graining spectral analysis in eight blood donors. Beat-by-beat R-R intervals and blood pressu...
