Method of recording contractions of isolated blood vessels with the aid of a photoresistor

An apparatus for recording the tone and contractions of isolated vessels of various animals is described. The principle of the method consists of recording changes in the volume of an isolated vessel filled with Ringer-Locke solution by means of a photoresistor.     

Romano-Ward syndrome initially diagnosed as epilepsy

Criteria of functional operability and indications for intraoperative volumetric monitoring of patients during extensive surgical procedures on the lung

The investigation included 32 patients after extensive operative interventions on the lungs: pneumonectomy with circular resection of the trachea bifurcation and different kinds of combined pneumonectomies. Methods of Doppler echocardiography and thermal dilution were used for studying the parameters of lesser circulation before, during and after operation. Patients with the initially impaired hemodynamics had more pronounced functional changes after surgical procedures. The shift limits of the main ultrasonic indices of the right ventricle function were determined in order to form a group of the higher prognostic risk.
