Η ΕΠΙΔΡΑΣΙΣ ΤΗΣ ΙΣΟΠΡΟΤΕΡΕΝΟΛΗΣ Η ΤΗΣ ΜΥΟΚΑΡΔΙΑΚΗΣ ΙΣΧΑΙΜΙΑΣ ΕΠΙ ΤΟΥ ΜΑΓΝΗΣΙΟΥ ΤΟΥ ΜΥΟΚΑΡΔΙΟΥ ΕΠΙ ΥΠΑΣΒΕΣΤΙΑΙΜΙΑΣ: πειραματική μελέτη
THE AIM OF THIS WORK WAS THE STUDY OF MYOCARDIAL MAGNESIUM CHANGES AFTER ADMINISTRATION OF ISOPROTERENOL OR CORONARY ARTERY LIGATION DURING HYPOCALCAEMIA. WE USED 34 ANAESTHETISED DOGS (6 GROUPS) AND CONNECTED THEM WITH ARTIFICIAL KIDNEY. HYPOCALCAEMIA WAS ACHIEVED IN GROUPS B, D, F. INTRAVENOUS ISOPROTERENOL WAS GIVEN IN GROUPS C, D AND CORANARY ARTERY LIGATION FOR 7 MIN WAS PERFORMED IN GROUPS E, F. MYOCARDIAL MAGNESIUM WAS MEASURED IN PART OF THE LEFT VENTRICLEIN ALL GROUPS. WE FOUND THAT HYPOCALCAEMIA ALONE DID NOT AFTER MYOCARDIAL MAGNESIUM ISOPROTERENOL RESULTED IN A DECREASE OF MAGNESIUM BUT DURING HYPOCALCAEMIA MAGNESIUM WAS INCREASED. CORONARY ARTERY LIGATION DID NOT CHANGE MAGNESIUM DURING NORMOCALCAEMIA BUT UNDER THE CONDITION OF HYPOCALCAEMIA INCREASED IT.IN CONCLUSION, ISOPROTERENOL OR ISCHAEMIA HAVE AN OPPOSITE EFFECT ON THE MYOCARDIAL MAGNESIUM IN HYPOCALCAEMIA COMPARED WITH THAT OF NORMOCALCAEMIC STATE,IN THE DIRECTION WHICH OFFERS PROTECTION TO THE MYOCARDIUM.
