[Comparative study of vasa vasorum and neointima in conduits for coronary artery bypass grafting].

Aim: This study was undertaken to investigate the preoperative incidence and severity of intimal hypertrophy, as well as the level of blood supply of arterial and venous conduits for coronary artery bypass grafting.

Material And Methods: Segments of the internal thoracic artery and great saphenous vein (n=13) were harvested pairwise during coronary artery bypass grafting and were then visualized by scanning electron microscopy in back-scattered electrons. The analysis of the incidence and thickness of intimal hypertrophy, as well as the calculation of the number and the area of the vasa vasorum were performed using the programme ImageJ.

[Mechanisms of coronary flow recovery in the isolated heart during reperfusion with cardioprotective liposomal emoxipin form].

In the experiments on the isolated perfused rat heart the effects of liposomes, containing different concentrations (0.25 and 0.1 mg/mL) of emoxipine, on coronary flow restoration after total normothermic ischemia and reperfusion were studied.

[Effect of different concentrations liposomal emoxipine on coronary flow, contractive and pump function of the isolated rat heart after normotermic ischema and further reperfusion].

In the experiments on the isolated perfused rat heart we studied the effects of liposomes containing different concentrations (0.25 and 0.1 mg/ml) of emoxipine on coronary flow, contractive and pump function of the isolated heart, which was effected by total normothermical ischemia and reperfusion.
