The Bezold-Jarisch Reflex in a Patient With Stanford Type A Acute Aortic Dissection.

Background: The Bezold-Jarisch reflex is a depressor reflex of the heart due to the preferential distribution of vagal nerves in the inferior wall of the left ventricle. We report a case of Stanford type A acute aortic dissection, in which coronary spastic angina caused the Bezold-Jarisch reflex in the acute phase.

Case Report: A 53-year-old man presented with left chest pain and cold sweating.

Direct chiral separation of troglitazone stereoisomers using reversed-phase high-performance liquid chromatography.

A simple HPLC method for the direct chiral separation of troglitazone stereoisomers was developed. The separation was performed on a reversed-phase cellulose-derivertized chiral column (Chiralcel OJ-R) using a mobile phase consisting of methanol-acetic acid (1000:1, v/v) at a flow rate of 0.5 ml/min.
