In this study we evaluate the onion aqueous extract (AE) effect on water flow and electrolytes in anesthetized Wistar rats, besides we also evaluate arterial pressure alterations. Two groups were studied: Group 1 (control) - oral tratment with 1.0 mL of distilled water, and Group 2 (experimental) - oral treatment with 1.0 mL of AE 20%. The rats were anesthetized and we canulate the trachea, left carotide artery (for arterial pressure measurement and blood collecting), jugular vein (to execute inulin perfusion - to register glomerular filtration), and urinary bladder (to collect urine). The Group 1 results had shown that the animals had not presented significant alterations (p>0.05) in the analyzed parameters. The animals of Group 2 had a significant reduction (p<0.05) in the arterial pressure (22.0%). However, there were not significant alterations in renal parameters (p>0.05). These results show that the treatment with the AE lead a hypotensor effect in anesthetized Wistar rats, but not followed by renal parameters alterations.24-29porArterial hypertensionOnionRats wistarRenal functionelectrolyteinulinonion extractanesthesiaanimal experimentarterial pressurebronchitiscannulationcardiovascular diseasecarotid arterycontrolled studycoughingdiuresisdrug effectelectrolyte balanceglomerulus filtrationhypertensionhypotensionjugular veinkidney functionnonhumanrattracheatraditional medicineurine volumewater flowAllium cepaAnimaliaRattus norvegicusArtigoAcesso aberto2-s2.0-321444474302-s2.0-32144447430.pdf
