RESUMEN
Surgical management of type A acute aortic dissection by the Bentall procedure involves attachment of the native coronary arteries to a synthetic valved-graft conduit (mechanical or biological aortic valve). In patients with normal anatomy and with careful surgical technique, formation of coronary buttons has been successful, and anastomotic complications after this procedure are rare. However, we describe the development of postoperative myocardial ischemia in a 46-year-old man caused by coronary button kinking after the Bentall procedure and reflect how one may avoid returning to the operating theater and still achieve a good outcome.

This inventory evaluates toxicological effects and hepatoprotective potential of Clerodendron glandulosum.Coleb (CG) aqueous extract. Acute and subchronic toxicity tests were performed using Swiss albino mice as per the guideline of Organisation for Economic Cooperation and Development (OECD). Also, hepatoprotective potential of CG extract was examined in experimental model of carbon tetrachloride (CCl( 4))-induced hepatotoxicity. Acute and subchronic toxicity tests revealed that CG extract is non-toxic and its median lethal dose (LD(50)) value is >5000 mg/kg bodyweight. Also, rats pretreated with CG extract followed by administration of CCl(4) recorded significant decrement in plasma marker enzymes of hepatic damage, total bilirubin content and hepatic lipid peroxidation. While, hepatic reduced glutathione, ascorbic acid content, activity levels of superoxide and catalase and plasma total protein content were significantly increased. Microscopic examination of liver showed that pretreatment with CG extract prevented CCl(4)-induced hepatic damage in CG + CCl( 4) group. CG extract has hepatoprotective potential by modulating activity levels of enzymes and metabolites governing liver function and by helping in maintaining cellular integrity of hepatocytes that is comparable with that of standard drug silymarin. CG extract exhibits potent hepatoprotective activity against CCl(4)-induced hepatic damage but does not exhibit any toxic manifestations.
