Effect of carvedilol and vitamin C on the myocardial muscle NF-κB expression in azithromycin-injected rats. (a) Control showing negative (−) staining for NF-κB; (b) azithromycin-treated rats showing marked (+++) NF-κB positivity; (c) carvedilol + azithromycin-treated rats showing negative (−) NF-κB positivity; (d) vitamin C + azithromycin-treated rats showing moderate (++) NF-κB positivity (sections are immunohistochemically stained ×20).
