Paraneoplastic pemphigus without antibodies to desmoglein 1 and 3.

Paraneoplastic pemphigus is a severe autoimmune blistering disease presenting in the setting of underlying malignancy. Paraneoplastic pemphigus is associated with diffuse painful stomatitis throughout the oral cavity with extension to the lips. The cutaneous findings are varied and have been described as lichenoid, pemphigoid, and targetoid lesions.

Hemorheological and hemodynamic effects of high molecular weight polyethylene oxide solutions.

Hemorheological and hemodynamic effects of high molecular weight polyethylene oxide (PEO) solutions have been studied in vitro and in vivo at 30 experimental dogs. The rheological behaviour of the PEO solutions and of blood samples has been assessed by rotational viscometers at 20 degrees C, 25 degrees C and 37 degrees C. An addition of PEO solutions to the blood in vitro has modified its rheological behavior, depending on the shear rates, concentration and temperature.
