[Imaging port wine stain by optical coherence tomography].

Optical coherence tomography is an appropriate imaging method for biomedical science, due to its advantages of noninvasive nature, high resolution and fast imaging speed. Because most biological tissues have the characteristic of high scattering coefficient, OCT system can just obtain the structural images several millimeters below the surface of the tissues. The superficial depth of OCT's penetration limits application in dermatology field.

Isobolographic analysis of the antinociceptive interactions between ketoprofen and paracetamol.

The present study was undertaken to evaluate the antinociceptive interaction between paracetamol and ketoprofen. The antinociceptive effect of oral administration of the drugs alone or in combination was evaluated using the mouse abdominal constriction test. The data were interpreted by isobolographic analysis to establish the nature of the interaction.
