Inhibition of aldose reductase: 13C NMR studies in isolated peripheral nerve.

We report 13C NMR measurements of the flux through aldose reductase in isolated rat sciatic nerve, and its inhibition by an aldose reductase inhibitor of the sulphonylnitromethane class. [1-13C] galactose was used as substrate, and the rate of production of [1-13C] dulcitol was measured. Quantitation required the use both of internal extracellular, and external, standards.

Kinetic characteristics of ZENECA ZD5522, a potent inhibitor of human and bovine lens aldose reductase.

Aldose reductase (aldehyde reductase 2) catalyses the conversion of glucose to sorbitol, and methylglyoxal to acetol. Treatment with aldose reductase inhibitors (ARIs) is a potential approach to decrease the development of diabetic complications. The sulphonylnitromethanes are a recently discovered class of aldose reductase inhibitors, first exemplified by ICI215918.

Hip arthroscopy.

One of the more recent advances in keyhole surgery is hip arthroscopy. This particular area of arthroscopic surgery has been relatively neglected until recently but its development has widened the options open to the orthopaedic surgeon when considering the most appropriate treatment for the patient. Historically, attempts at hip arthroscopy were first reported in 1931 by Burman.

Ponalrestat: a potent and specific inhibitor of aldose reductase.

Many of the complications of diabetes appear to be closely linked to increased conversion of tissue glucose to sorbitol which is catalysed by aldose reductase (aldehyde reductase 2, ALR2). Inhibition of ALR2 could, therefore, lead to a reduction in the development of diabetic complications. Ponalrestat ["Statil" (a trademark, the property of Imperical Chemical Industries PLC), "Prodiax" (a trademark, the property of Merck, Sharp and Dohme), ICI 128436, MK538] inhibits ALR2 from a number of sources.
