Nonlinear electrophoresis of protein-detergent complexes.

A comparatively new procedure is described for the nonlinear electrophoresis of proteins. Movement and separation of complexes formed by proteins and ionic detergents is first experimentally demonstrated for SDS rainbow colored protein molecular weight markers (Amersham). This result was revealed by SDS-PAGE in an asymmetric zero average pulsed electric field with a peak amplitude of up to 300 V cm(-1) and a frequency of 100 Hz.

[Results of improved esophago-intestinal anastomosis and jejuno-gastroplasty application in gastrectomy].

Initial results of gastrectomy in 48 patients with the use of improved by the authors method of performing vertical end-to-side cuff shaped anastomosis and newly developed method of establishment of a new food reservoir by jejunogastroplasty are reported.

[An improved antireflux esophageal-intestinal anastomosis in gastrectomy].

An improved method for the formation of a cuff-like end-to-side vertical anastomosis between the esophagus and intestine with antireflux properties was applied in gastrectomy in 142 patients with predominantly stage III gastric carcinoma. The postoperative mortality was 3.5%.
