Gas jet transection of liver parenchima: experimental research.

Background: There exists a great variety of liver parenchyma transection techniques. The objective of this research is to develop a new method of liver transection, and to compare it with the traditional ones.

Methods: An original gas jet transection method of biological tissues and the apparatus "Pneumojet" to make the method practicable were developed in our institute.

[Surgical treatment of a solitary hepatic abscess].

Retrospective analysis of the treatment results of 120 patients, suffering solitary hepatic abscess (SHA), was conducted. The sanation methods, in accordance to technology, the treatment impact intensity and aggressiveness, may be divided on three lines: aspirational, draining and resectional. The method of sanation is selected on the background of morphological peculiarities of abscess--its sizes, by presence of sequesters, divisioning septs, dense rigid capsule, grade of periprocess.

Spontaneous emission of singlet oxygen near dielectric nano-objects and radiative diagnostics of bio-objects.

We investigate modifications of a spontaneous emission rate near the surface of the hemoglobin-like dielectric structure in the long-wavelength limit. We demonstrate that notwithstanding the small size of the dielectric structure, an influence of its shape cannot be neglected. Even for moderate dielectric contrasts one can expect having significant and detectable enhancement or suppression of the spontaneous emission rate near the surface of the biological macromolecule.

[Application of mini-invasive technologies in the treatment of gastrointestinal bezoars].

The data on etiology, clinical signs, diagnosis and variety of approaches to the treatment of gastrointestinal bezoars were presented, basing on the worldwide literature analysis. The results of surgical treatment of patients for bezoars, using miniinvasive methods, are presented.
