[Structure of the double electric layer at membrane/aqueous solution interfaces in the presence of tetrapentylammonium cations].

Data are presented on the conductivity of bilayer lipid membranes of phosphatidilethanole amine with different surface charges in the presence of tetrapentylammonium chloride. It follows from the analysis of experimental data that to describe the effect of surface charge on membrane conductivity it is necessary to use a complicated model of double electric layer. Only in some cases Gouy-Chapman theory well describes the experimental results.

Vein graft in toe to hand transfers.

These authors describe indications, techniques, short- and long-term results of toe to hand transfers using the vein grafts. 145 toe to hand transfers were performed in 115 patients. Fifty cases necessitated 44 vein grafts in 37 patients; there were 41 vein to artery and 3 vein to vein grafts carried out. The grafts were used to bridge defects of a vessel over 55 mm (usually in patients with heavy posttraumatic scar formation and/or distrophic changes resulting from burns and frost-bite in the vessel stumps, or in the main vessel nourishing the transplant), both in primary surgery and in re-operation following the resection of the thrombosed microanastomosis. Success was achieved in 28 patients who underwent primary interposition of vein grafts, with 34 survivals (90%) of 38 transferred toes. That exceeded the average survival rate of 84%. In 9 patients vein grafting of arteries followed the resection of the thrombosed microanastomoses and resulted in 5 survivals of 12 transferred toes. In 6 cases vein grafts to arteries were performed both intraoperatively and in re-operation. In this group of patients 7 of 8 transferred toes survived for re-operation had been prompt. Venous grafting in toe to hand transfers carried out without delay and in full conformity with the indications, produced results statistically similar to those obtained in procedures involving no venous grafting.

Reconstructive microsurgery in treatment of lymphoedema in extremities.

A total of 510 cases of primary and secondary lymphoedema in upper and lower extremities have been examined with two thirds of primary lymphoedema cases among them. Radical mastectomy combined with irradiation has led to the development of obstructive lymphoedema of upper limbs in most patients. 230 patients with primary and secondary lymphoedema have been subjected to microlymphatic surgery and lymphaticovenous anastomoses have been carried out with microsurgical techniques. Limb volume measurement, the results of direct lymphangiography and intralymphatic pressure reading were taken into account to select patients suitable for microlymphatic surgery. Most favourable results have been obtained in secondary obstructive lymphoedema cases (total 81.2%) due to well-marked hypertension in lymphatic vessels that contributes to better functioning of the lymphaticovenous anastomoses made in a patient.
