The present study investigated the protective effect of diethylcarbamazine in inhibiting nuclear factor (NF)-κB activation in isoproterenol‑induced acute myocardial infarction (AMI) rats through the poly ADP ribose polymerase (PARP) pathway. Male albino Wistar rats were injected subcutaneously with isoproterenol (100 mg/kg/day) for 2 days to induce an AMI model. Diethylcarbamazine (50 mg/kg) was administered by gavage for 12 days prior to the isoproterenol-induced AMI. It was noted that diethylcarbamazine significantly inhibited AMI‑induced casein kinase and lactate dehydrogenase levels, and reduced the AMI‑induced wet heart weight to body weight ratio in AMI rats. Diethylcarbamazine treatment significantly weakened reactive oxygen species production and reduced the levels of tumor necrosis factor (TNF)‑α, interleukin‑6 and NF‑κB/p65 in AMI rats. Western blotting demonstrated that diethylcarbamazine significantly suppressed the AMI‑induced inducible nitric oxide synthase (iNOS), transforming growth factor (TGF)‑β1, cyclooxygenase‑2 (COX‑2) and PARP protein expression in AMI rats. The results demonstrated that the protective effect of diethylcarbamazine inhibited isoproterenol‑induced AMI through the suppression of inflammation, iNOS, TGF‑β1, COX‑2 and the PARP pathway, and revealed the clinical potential of diethylcarbamazine for therapeutic and clinical applications.

Specialized clothing or equipment worn for protection against health hazards. Personal Protective Equipment may include MASKS; RESPIRATORY PROTECTIVE DEVICES; HEAD PROTECTIVE DEVICES; EYE PROTECTIVE DEVICES; EAR PROTECTIVE DEVICES; PROTECTIVE CLOTHING; and protective footwear.
A dual inhibitor of both cyclooxygenase and lipoxygenase pathways. It exerts an anti-inflammatory effect by inhibiting the formation of prostaglandins and leukotrienes. The drug also enhances pulmonary hypoxic vasoconstriction and has a protective effect after myocardial ischemia.
An antiviral antibiotic produced by Cephalosporium aphidicola and other fungi. It inhibits the growth of eukaryotic cells and certain animal viruses by selectively inhibiting the cellular replication of DNA polymerase II or the viral-induced DNA polymerases. The drug may be useful for controlling excessive cell proliferation in patients with cancer, psoriasis or other dermatitis with little or no adverse effect upon non-multiplying cells.
Liver disease lasting six months or more, caused by an adverse drug effect. The adverse effect may result from a direct toxic effect of a drug or metabolite, or an idiosyncratic response to a drug or metabolite.
A disorder of cardiac function secondary to hypersensitivity reactions. It is characterized by coexistence of acute coronary syndromes and cardiac MAST CELL and PLATELET ACTIVATION. It may be induced by exposure to drugs (e.g., antibiotics, anesthetics, contrast media), food, and environmental triggers (e.g., insect bites and stings, poison ivy).
