Stroke is the leading cause of disability in much of the world, with few treatment options available. Following unilateral stroke in rats, inosine, a naturally occurring purine nucleoside, stimulates the growth of projections from the undamaged hemisphere into denervated areas of the spinal cord and
Cerebral infarct (stroke) often causes devastating and irreversible losses of function, in part because of the brain's limited capacity for anatomical reorganization. The purine nucleoside inosine has previously been shown to induce neurons to express a set of growth-associated proteins and to
BACKGROUND
Although myocardial ATP is essential for myocardial viability and ventricular function, it is a major source of free radical substrates for endothelial xanthine oxidase. Correlation between myocardial ATP and ventricular function has been hindered by the impact of ATP catabolites on
The nucleoside adenosine (ADO) is a neuromodulator in brain. ADO and its metabolite inosine (INO) have been shown to increase cell viability in stroke models. During ischemia, extracellular levels of both ADO and INO are increased. In this study, we treated rat cortical neurons with
To perform a pharmacoeconomic analysis of the most frequently prescribed neuroprotective medicines for treating patients with mild ischemic stroke in the acute and early rehabilitation periods in the Russian Federation.Three medical technologies were The action of inosine (2.5, 5, or 10 mg.kg-1.min-1 iv) was investigated in open chest rats (n = 46) and guinea pigs (n = 16). Left ventricular and aortic pressures, dP/dtmax, and stroke volume were measured. Additionally, isovolumic peak pressure and peak dP/dtmax were measured during short
We determined the mechanical and metabolic effects of graded myocardial ischemia in 23 open-chest, anesthetized pigs. By connecting the midportion of the left anterior descending artery (LAD) to the carotid artery via a constant volume, calibrated pump, we reduced the flow in the LAD to 0, 25, 50,
The energetic role of inosine (INO) remains controversial. The aim of the present study was first to test whether endogenous INO consumption/production correlates with regional myocardial contractile performance and second to test whether locally increased levels of INO influence contractility and
A prospective high performance liquid chromatography (HPLC) study was performed in eighteen patients with head injury and stroke and four control volunteers to evaluate creatinine and purine metabolites concentration (adenosine, inosine, hypoxanthine, uric acid) in cerebrospinal fluid (CSF). The
Stroke is a leading cause of death and disability. Here, we examine whether point-of-care measurement of the purines, adenosine, inosine and hypoxanthine, which are downstream metabolites of ATP, has potential to assist the diagnosis of stroke. In a prospective observational study, patients who were
Despite years of research, no effective therapy is yet available for the treatment of traumatic brain injury (TBI). The most prevalent and debilitating features in survivors of TBI are cognitive deficits and motor dysfunction. A potential therapeutic method for improving the function of patients
Buyang Huanwu Decoction (BYHWD) is a well-known traditional Chinese medicine prescription which is used to treat ischaemic stroke and stroke-induced disabilities. However, the exact mechanism underlying BYHWD's amelioration of ischaemic stroke and its effective constituents remain unclear. The
BACKGROUND
Adenosine deaminase (ADA) catalyzes the irreversible hydrolytic deamination of adenosine to inosine. The purpose of this study was to determine the plasma activities of total adenosine deaminase (ADA T), and its isoenzymes, ADA1 and ADA2, and ADA1/ADA2 ratio of male and female ischemic
Recovery after stroke and other types of brain injury is restricted in part by the limited ability of undamaged neurons to form compensatory connections. Inosine, a naturally occurring purine nucleoside, stimulates neurons to extend axons in culture and, in vivo, enhances the ability of undamaged
OBJECTIVE
Purinergic nucleoside inosine elicits protection and regeneration during various injuries. The purpose of this study was to examine the protective effects of inosine against cerebral ischemia.
METHODS
Adult Sprague-Dawley rats were anesthetized. Inosine, hypoxathine, or vehicle was
