Biochemistry and cell ultrastructure changes during senescence of Beta vulgaris L. leaf.

The comparative study of biochemical and ultrastructure features in senescing sugar beet (Beta vulgaris L.) leaves was carried out. One group of plants was grown under normal conditions in washed river sand and poured in turn with nitrate-containing mineral solution or water (N plants).

[Use of videolaparoscopy in treatment of peritonitis of appendicular origin].

Videolaparoscopic appendectomy was carried out in 108 patients with acute destructive appendicitis complicated by peritonitis. Local peritonitis was noted in 65 patients, diffuse peritonitis in 33 patients, periappendicular abscess in 10 patients. Postoperative complications were observed in 6 (5.

[Using laparoscopic cholecystectomy in treatment of destructive forms of acute cholecystitis].

Videolaparoscopic cholecystectomy was performed in 352 patients with acute destructive cholecystitis, 236 (67%) of patients having phlegmonous cholecystitis or empyema of the gallbladder, 116 patients (33%) gangrenous cholecystitis. In 74 patients (21%) the course of acute cholecystitis was complicated by the formation of paravesical infiltration or abscess. Standard laparoscopic cholecystectomy was fulfilled in 250 patients (71%), in 102 patients not traditional methods of endovideosurgical dissection of the gallbladder were used, in particular laparoscopic cholecystectomy from the bottom in 18 patients (5.

[Causes of postoperative lethality in acute cholecystitis and measures to decrease it].

The authors have made a comparative analysis of postoperative lethality in acute cholecystitis for the period of 25 years. The clinical material included 1383 operated patients, of them 87 (6.3%) patients died.
