Investigation of Taurine Derivative Magnesium-Bis-(2-Aminoethanesulfonic)-Butadioateon Alleviation of Neurological Defects in Simulated Hemorrhagic Stroke in Rats

Stroke or ischemia is caused by a blockage in a specific blood vessel that partially or completely reduces the blood flow to the brain. Nutritional factors such as antioxidants and healthy eating patterns are important variables in preventing stroke. Molecular composition properties such as molecular binding and screening can be used to evaluate the specific activity and morphological changes. The present study aimed to evaluate the effectiveness of pharmacological correction of the consequences of a hemorrhagic stroke in rats with a new derivative of taurine magnesium-bis-(2-aminoethanesulfonic)-butadioate. The animals (n=170) were divided into four groups as follows: 1) control group (n=20), 2) group 2 suffered a hemorrhagic stroke without pharmacological correction (n=50), 3) group 3 (n=50) underwent simulation of hemorrhagic stroke received Taurine at the dose of 50 mg/kg, 4) Group 4 underwent simulation of hemorrhagic stroke with correction of hemorrhagic stroke with magnesium-bis-(2-aminoethanesulfonic)-butadioate at the dose of 150 mg/kg (LKHT 3-17) (n=50). Hemorrhagic stroke was induced by transfusing autologous blood into the parietal lobe of the right hemisphere of the brain. Lethality, neurological status, locomotor, and exploratory behavior, as well as the morphological pattern of the brain damage, were assessed on the 1st, 3rd, and 7th days after the pathology simulation. Neurological deficit was determined in animals by the McGrow stroke index scale. The locomotor and exploratory behavior was evaluated using the Acti-track software and hardware complex. Two criteria were considered when assessing morphological changes in the brain: the average thickness of the cerebral cortex (in micrometers) and the number of neurons without degenerative changes. LKHT 3-17 (150 mg/kg) and taurine (50 mg/kg) reduced lethality by 1.7 and 1.36 times, respectively, on the 3rd day after stroke compared to that of the control (p<0.05). In parallel, a neurological deficit was effectively corrected LKHT 3-17 and taurine to 5.3±0.8 and 6.5±0.9, respectively, on the 1st day in contrast to the control of 8.1±0.7 points. The locomotor and exploratory behavior was significantly different on the 7th day and was accompanied by a significant increase in total activity under the influence of LKHT 3-17 to 491 conventional units (CU) compared to the control of 110 conventional units. On the 1st day, the thickness of the cortex was 1943.7±44.08 µm, and 1491.0±38.61 µm in the control and LKHT 3-17 groups, respectively. The number of neurons without neurodegenerative changes prevailed in LKHT 3-17 group (18.7±4.32), and the lowest number was observed in the group without pharmacological correction of the pathology (14.3±3.78). The taurine derivative magnesium-bis-(2-aminoethanesulfonic)-butadioate, which is a combination of the amino acid,  magnesium ion, and succinic acid, decreases the neurological deficits, lethality, and enhances the locomotor and exploratory behavior in experimental hemorrhagic stroke in rats. The effect of the studied medication on the dynamics of molecular pathophysiological mechanisms occurring in the cell requires additional research.
