RESUMEN

Gestational diabetes mellitus (GDM) and preeclampsia (PE) are common pregnancy complications with similar risk factors. Although GDM is associated with PE, the exact mechanism underlying the association is unclear. The objective of this work was to study the morphofunctional and molecular changes in the placenta and peripheral blood in PE and GDM. Local and systemic changes in the production of several placental proteins were assessed along with markers of inflammation and metabolic disorders. Expression of placental lactogen, trophoblastic ß1-glycoprotein, placental alpha-1-microglobulin, and proteinase 3 in villi was found to change in complicated pregnancy groups. Similarity of underlying pathogenic mechanisms was demonstrated for PE and GDM.

RESUMEN

We studied the expression of pluripotency factor Oct-4 and the intensity of apoptosis in the uterus during spontaneous and immune abortions in mice. Increased expression of factor Bax and reduced protein Bcl-2 synthesis in cells of the decidual membrane and decreased Oct-4 expression in the myometrium and perimetrium were detected. Thus, both spontaneous and immune-dependent abortions impair the apoptosis processes in the decidua and the formation of a pool of Oct-4+ cells in the uterus. In immune-dependent abortions, the intensity of apoptosis of decidual cells was lower than in spontaneous abortion. Low expression of the transcription factor Oct-4 in the myometrium and perimetrium characterizes pregnancy failure irrespective of its mechanisms.

RESUMEN

Spontaneous proliferative activity of splenocytes in female CBA mice and the response of these cells to antigens of allogeneic male BALB/c and DBA/2 mice in a mixed splenocyte culture were evaluated by 3H-thymidine incorporation in different pregnancy models. ♀CBA×♂BALB/c mating was used for modeling physiological pregnancy. Spontaneous abortions were reproduced by abortion-prone ♀CBA×♂DBA/2 mating. In order to simulate immunostimulant-induced and immunostimulant-potentiated abortions, 0.83 mg/kg muramyl dipeptide ß-heptylglycoside was intraperitoneally injected to CBA females mated with BALB/c or DBA/2 males, respectively, on gestation days 5 and 7. The increase in the rate of embryo resorption in the models of spontaneous, induced, and potentiated abortions occurred against the background of an increase in the level of spontaneous proliferation of splenocytes and a decrease in their reactivity to paternal antigens on gestation day 9.

RESUMEN

The article deals with usage of nondihydropiridine calcium antagonists--verapamil and dilthiasem--in treating patients with arterial hypertension, cardiomyopathy and arrhythmia, for secondary prevention of IHD. Data also concern cardio-, angio--and nephroprotective activity of the medications, their ability to prevent left ventricle hypertrophy, possible usage in patients after myocardial infarction. The authors also discuss problems of tolerance and safety of calcium antagonists with prolonged action vs. those with short-term action.

RESUMEN

Community-acquired pneumonia is one of prevalent infectious respiratory diseases. Adequate treatment of community-acquired pneumonia, with consideration of the disease severity and microbial resistence, remains extremely topical. The article covers contemporary views of community-acquired pneumonia treatment standards. The authors described results of personal research aimed to study antibacterial treatment for community-acquired pneumonia on outpatient basis over 2004-2012, evaluated correspondence of the treatment to the national clinical recommendations.

RESUMEN

The paper concerns the problem of implant-based oral rehabilitation in complex alveolar bone topography. The study included 56 patients with partial and full teeth loss and significant alveolar bone atrophy Resonance frequency rates were used to assess intraosseous dental implants stability showing its improvement after alveolar bone augmentation procedures.

RESUMEN

Minimally invasive soft tissue augmentation is a challenging problem for dentists. Use of autogenous fibroblast of oral mucosa is a promising method. The paper represents the results of preclinical, clinical and laboratory studies on the use of autogenous oral mucosa fibroblasts (AOMF) for gum recession correction. The results confirm statistically significant gum thickness augmentation and gum recession decrease after three weekly AOMF injections. The effect lasted for at least 9 months.

RESUMEN

Progress in modern esthetic dentistry is largely determined by the development of new technologies and their introduction into practice. One of the most perspective research trends are cell technologies based on the use of cell cultures for tissue repair in various abnormalities. Published data demonstrate the possibility of using autologous fibroblasts for repair of periodontal tissues and correction of postoperative retraction of the alveolar processes.

RESUMEN

Ethanol or acetone inhalation resulted in a reduction in motor activity in rats, affecting largely their explorative behavior. The biochemical parameters of free-radical processes (catalyse and SOD activities, LPO levels) remained unchanged in the inhaling animals. Ethanol or acetone inhalation caused a significant decrease in blood catalyse activity and serum LPO levels. The acetone- and ethanol-induced changes in the activity of ceruloplasmin were heterodirectional. It can be concluded that it is useful to study the biochemical parameters of serum free-radical processes and to employ the findings in the therapy of inhalation toxicomanias.
