The palmaris profundus, a rare sight during carpal tunnel release.

Palmaris profundus is a rare anatomical anomaly that may complicate carpal tunnel release. We discuss a recent case of carpal tunnel syndrome and its surgical release, whilst reviewing the published anatomical and surgical literature.

Antiviral properties of ent-labdene diterpenes of Andrographis paniculata nees, inhibitors of herpes simplex virus type 1.

Andrographolide, neoandrographolide and 14-deoxy-11,12-didehydroandrographolide, ent-labdene diterpenes isolated from Andrographis paniculata showed viricidal activity against herpes simplex virus 1 (HSV-1). None of these compounds exhibited significant cytotoxicity at viricidal concentrations.
