Differential activation of sympathetic nervous system and release of catecholamines during neuroglycopenia in awake rats

Autor: O. A. Tyurmina, Kuz'min Ai, Medvedev Os

Publikováno v: Bulletin of Experimental Biology and Medicine. 124:1069-1072

Neuroglycopenia induced by administration of 2-deoxy-d-glucose (125–375 mg/kg) is characterized by bradycardia and increased sympathetic activity, overall release of norepinephrine, plasma epinephrine, and norepinephrine at stable arterial pressure

Allopurinol-Enhanced Postischemic Recovery in the Isolated Pat Heart Involves Repletion of High-Energy Phosphates

Autor: Enno K. Ruuge, Oleg I. Pisarenko, Valery I. Kapelko, Kuz'min Ai, Irina Studneva, Vladimir L. Lakomkin, Alexander A. Timoshin

Publikováno v: Biochemical Medicine and Metabolic Biology. 51:16-26

The effects of allopurinol (AP) on functional and metabolic recovery of the isolated rat heart after global ischemia were studied. Hearts were subjected to aerobic perfusion (30 min), cardioplegic infusion (5 min), normothermic ischemia (37 min), and

A microdialysis investigation of the release of norepinephrine in the hypothalamus induced by 2-deoxyglucose in awake rats

Autor: M. B. Bogdanov, Kuz'min Ai, Medvedev Os

Publikováno v: Neuroscience and Behavioral Physiology. 22:436-439

The level of norepinephrine in the extracellular space of the lateral hypothalamus was measured by means of intracerebral microdialysis in awake rats. The introduction of desipramine (10 mumole) into the perfusing medium did not affect the basal leve

Dynamics of DNA-binding activity of cytoplasmic proteins during autoproteolysis

Autor: Kuz'min Ai, Zamotrinskiĭ Av

Publikováno v: Bulletin of Experimental Biology and Medicine. 110:1352-1355

The quality proteolysis changing of DNA-binding proteins of cytosol mice liver was studied by affinity chromatography on DNA-cellulose. It is shown that neutral proteolysis leads to the second peak of DNA binding.

Microdialysis study of ischemia-induced hydroxyl radicals in the canine heart

Autor: Alexander A. Timoshin, Kuz'min Ai, Medvedev Os, Tskitishvili Ov, L. I. Serebryakova, Enno K. Ruuge

Publikováno v: Experientia. 50:677-679

A new experimental approach for spin-trapping of oxygen radicals in a selected region of the heart in situ is described. This approach is based on microdialysis, and it permits the detection of oxygen radicals in conditions of local ischemia and rest

The effect of histamine receptor antagonists on stress-induced catecholamine secretion: an adrenomedullary microdialysis study in the rat

Autor: Maria V Zaretskaja, Kuz'min Ai, Medvedev Os, Dmitry V. Zaretsky, Evgenyi I Chazov, E. I. Kalenikova

Publikováno v: European journal of pharmacology. 378(3)

The effects of pretreatment with selective histamine receptor antagonists on changes in sympathoadrenal activity and haemodynamics, induced by 60-min immobilization stress, were studied in conscious rats. Using adrenomedullary microdialysis, it was s

Comparison of the effects of 2-deoxyglucose and immobilization on secretion and synthesis rate of catecholamines in the adrenal gland: a microdialysis study in conscious rats

Autor: Dmitry V. Zaretsky, Medvedev Os, Kuz'min Ai, Chazov Ei, V. M. Pogorelov

Publikováno v: Acta physiologica Scandinavica. 155(2)

Using microdialysis, extracellular 3,4-dihydroxyphenylalanine (DOPA), noradrenaline (NA) and adrenaline (AD) concentrations in the adrenal gland were monitored in conscious rats during and after 60 min of immobilization (IMM) as well as after injecti

Mechanisms of Differential Cardiovascular Responsiveness to 2-Deoxyglucose—Induced Central Glycopenia in Conscious Spontaneously Hypertensive and Wistar Kyoto Rats

Autor: Ararat D. Gjulumjan, Kuz'min Ai, Olga A. Tjurmina, Michael B. Bogdanov, Azizul M. Hoque, Vladimir N. Selivanov, Medvedev Os

Publikováno v: Central Neural Mechanisms in Cardiovascular Regulation ISBN: 9781461598367

It is well established that a variety of emotional stresses provoke release of catecholamines from the sympathoadrenal medullary system (Cannon, 1929; Kvetnansky et al., 1979), but the relationship between stress, adrenal catecholamines, and high blo
