Role of Arogh, a polyherbal formulation to mitigate oxidative stress in experimental myocardial infarction

Area of Science:

• Cardiovascular Research
• Pharmacology
• Biochemistry

Background:

• Isoproterenol-induced myocardial infarction in rats is a common model for studying heart damage.
• This condition leads to decreased activity of key antioxidant enzymes in heart tissue.
• Serum levels of antioxidants like glutathione and vitamins E and C are reduced, while lipid peroxides increase.

Purpose of the Study:

• To investigate the antioxidant role of Arogh in preventing isoproterenol-induced myocardial infarction in rats.
• To evaluate the effect of Arogh on the activity of cardiac antioxidant enzymes.
• To assess the impact of Arogh on serum antioxidant levels and lipid peroxide markers.

Main Methods:

• Rats were administered isoproterenol to induce myocardial infarction.
• Arogh was administered as a pretreatment.
• Activity of heart tissue antioxidants (glutathione, superoxide dismutase, catalase, glutathione peroxidase, glutathione-s-transferase) was measured.
• Serum levels of ceruloplasmin, glutathione, vitamins E and C, and lipid peroxides were analyzed.

Main Results:

• Isoproterenol administration significantly decreased heart tissue antioxidant enzyme activity.
• Serum antioxidant levels (glutathione, vitamins E and C) were substantially decreased, with a rise in lipid peroxides.
• Arogh pretreatment significantly suppressed these isoproterenol-induced alterations.

Conclusions:

• Arogh exhibits a significant protective antioxidant role against isoproterenol-induced myocardial infarction in rats.
• Arogh pretreatment helps maintain the activity of endogenous antioxidant enzymes and levels of key serum antioxidants.
• These findings suggest Arogh's potential therapeutic value in managing myocardial infarction.
