Abstract
Cardiac arrest (CA) is a sudden interruption in
the effective blood flow due to heart failure. The current research aimed to
conduct the pathophysiological and histopathological analysis in the kidney in
asphyxial cardiac arrest rat model. Cardiac arrest was induced by intravenous
injection of vecuronium bromide (2 mg/kg), following stop of mechanical
ventilation. Rats were kept on the CA condition for 5 minutes. After that,
cardiopulmonary resuscitation (CPR) was done to achieve return of spontaneous
circulation (ROSC) following intravenous injection of epinephrine bolus (0.005
mg/kg), sodium bicarbonate (1 mEq/kg) and turn on mechanical ventilation. Then
Rats were sacrificed after cardiopulmonary resuscitation (CPR) following
asphyxial CA at 6 hrs, 12 hrs, 1 day, 2 days, and 5 days. The intensity of renal
injury measured by the serum levels of blood urea nitrogen (BUN), creatinine (Crtn).
Moreover, Hematoxylin & eosin, and Periodic Acid Schiff staining in the kidney
was done for evaluating the renal histopathological changes. Furthermore, COX-2
immunoreactivity and western analysis were performed in the kidney. Survival
rate declined following ROSC compared to the sham group, it showed 80% at 6 hrs
and decreased time-dependently to 8% at 5 days. In this study, serum BUN and
Crtn levels and renal histopathological scores significantly increased after
ROSC in CA. Moreover, COX-2 expression also increased after ROSC in comparison
to the sham group with its peak level at 5 days following CA. Renal histological
damage score and COX-2 expression were upregulated after ROSC following CA.
These results direct that COX-2 takes part in the asphyxial CA-induced ischemic
renal injury.
