Reaction of the Palatine Tonsillar Immunocompetent Cells to Irrigation of Crypts by Suspension of Silica Nanoparticles under Conditions of Chronic Tonsillitis.

We studied the response of neutrophils, macrophages, and mast cells to local application of silica nanoparticles (10-20 nm). Histological examination of tonsillar postoperative material from 6 patients aged 24-44 years with recurrent tonsillitis was carried out. Irrigation of the tonsillar lacunae was carried out over 5 days before bilateral tonsillectomy: on the right by Polysorb MP suspension (1 g/liter), on the left by saline.

[A rare observation of intralaryngeal aberrant goiter].

This paper was designed to report a rare observation of intralaryngeal aberrant goiter associated with goiter of the main thyroid tissue and chronic suppurative otitis media complicated by the polyp that causes occlusion of the auditory passage. The histomorphological investigation of the material harvested intraoperatively following rehabilitation of the purulent focus in the middle ear and the removal of the tumour from the inside of the right vestibular fold confirmed the diagnosis of colloid goiter.

[Hepatic tuberculosis with the development of fibrosis and concomitant steatohepatitis].

Tuberculous lesions of the liver frequently occur in autopsy material, even though most of them are clinically unapparent. Pathogenetically, hepatic tuberculosis is a manifestation of general military tuberculosis with the infection brought in through the hematogenous route (through the hepatic artery or the portal system) as a result of intestinal or mesenteric lymph node tuberculosis. We report a case of combination of hepatic tuberculosis and diabetes mellitus in a young woman with reference to the clinical course of the disease, its diagnostics and treatment.

[Morphogenetic features of reparative regeneration of acetate gastric ulcer under chronic exposure to pesticide--copper sulphate].

Using morphologic, histochemical, histoenzymatic methods, the authors studied morphogenesis of acetate gastric ulcer in 40 rats subjected to chronic enteral intake of copper-containing pesticide-- copper sulphate. Structural and metabolic basis for perverted regeneration of mucosa near the ulcer under continuous enteral exposure to toxic factor, dose dependence in chronization of acute gastric ulcer were established for the first time.

[Perftoran emulsion in complex therapy of critical lower limb ischemia].

The paper presents comparative assessment of treatment outcomes in patients with critical lower limb ischemia treated with conventional therapy or combined with ozonized Perftoran. The study included 72 patients with Fontain-Pokrovsky III stage ischemia caused by impaired distal leg circulation. Thirty five patients received intra-arterial injections of ozonized Perftoran in addition to conventional "base" therapy.

[A drop in "apparent" blood viscosity due to administration of high-molecular polymer capable of augmenting viscosity].

Influence of a high-molecular compound capable of augmenting viscosity, namely: polyethylene oxide Polyox WSR-301, on hemodynamic parameters in rat mesenteric microvessels was investigated. A substantial decrease in the arteriolar hemodynamic resistance caused by the polymer was revealed. Special research has shown that this reaction is not connected with a vasodilatation and, therefore, is caused by a reduction in the "apparent" viscosity of the blood, i.

[Influence of polyethylene oxide Polyox WSR-301 on the pressure in mesenteric arterial microvessels in rats pre-adapted to anti-orthostatic states].

High-molecular polymers apt to directly influence flow microstructure were tested as a fundamentally new method for correcting microhemodynamics in microgravity. Pressure in the mesenteric arterial microvessels was measured two weeks in rats adapted to the head-down suspension. Intravenous polyethylene oxide (Polyox WSR-301, end-concentration in the order of 2.

[Treatment of linea alba hernia and diastasis of rectus abdominis].

The asynchronous development of structural and metabolic disorders of aponeurosis, leading to the development of defects in sheath of the rectus abdominis is the major factor of hernia of linea alba formation. Development of diastasis of m. rectus abdominis is caused by primary structural and metabolic changes of myocytes caused by the extreme overload.

[The action of high-molecular linear polymers on the circulatory system].

An analysis of the hemodynamic consequences of the injections of long linear polymers with high molecular weight is introduced. These injections lead to an increase of the cardiac output, to a decrease of the blood pressure, and hence cause a reduction of the resistance to blood flow. It follows that such kind of polymers is able to normalize hemodynamics under some pathophysiological conditions, e.

[Congenital myoblastoma (a clinical case)].

A congenital myoblastoma in a newborn boy is described, developing on the maxillary gingiva. Histological examination showed it to be a myoma of myoblasts, Abrikosov's tumor. Examination after 2 years did not reveal a relapse of the tumor.

[Results of surgical treatment of diastasis of the rectus abdominis muscles].

The work gives a comparative analysis of the treatment of 249 patients with diastasis of the rectus abdominis muscles according to the degree of restoration of the working capacity, the existence of gastrointestinal discomfort, recurrence of the disease, and the dynamics of changes of the morphological and functional values of these muscles. The clinical and functional-morphological results were best after plastics of the anterior abdominal wall by the method suggested by the authors. With the use of this method the results were good in 40 (71.

[A decrease in the hydrodynamic resistance in the mesenteric arterioles of rats injected with the polyethylene oxide Polyox WSR-301].

The infusion of polyethylene oxide in anesthetised rats in a total dose of 10(-7) g/ml caused a 10-16% reduction in blood pressure. This injection has been associated with 17% decreased pressure (servo-nulling method) and 54% increased blood velocity (laser Doppler fluxmetry) in mesenteric arterioles (d - about 24 mu), but no increase in their internal diameter was observed (image-split method). Vasodilatation (adenosine, 10(-5) M) did not change the hemodynamic response of the arterioles to polymer infusion.
