U46619, a synthetic analogue of thromboxane A2 was used for modeling acute stable and reversible pulmonary arterial hypertension. Administration of U46619 in high doses led to vascular collapse and inhibition of cardiac function. The doses of U46619 were empirically selected that allow attaining the target level of pulmonary hypertension without systemic hemodynamic disturbances. The possibility of attaining the target level of pulmonary hypertension and reversibility of changes after terminatio...

We studied modulation of the expression of extracellular matrix proteins under conditions of meprin inhibition in rats with LPS-induced endotoxemia. Endotoxemia increased the expression of type I, III, IV collagens and fibronectin in the renal tissue and type III and IV collagens in the heart. Meprin inhibitor actinonin reduced expression of both meprins and genes of extracellular matrix proteins, but the intensity of this effect in the heart and kidney was different. Inhibition of meprins in en...

We studied the effect of a combination of three muramylpeptides from gram-negative bacteria (Polymuramyl) on hematological parameters, morphology of the spleen, and serum cytokine level in mice with B16 melanoma treated with cyclophosphamide. Intraperitoneal administration of cyclophosphamide to tumor-bearing animals sharply reduced the number of leukocytes, especially neutrophils, in the blood and depleted the cellular composition of the spleen white pulp. Subsequent three daily intramuscular i...

The anxiolytic and analgesic properties of compound ALM-802, a cardiotropic linear methoxyphenyltriazaalkane derivative, combining pharmacophore elements of p-FOX inhibitors trimetazidine and ranolazine were studied in vivo. In the elevated plus-maze test, ALM-802 after acute intraperitoneal administration in doses of 1-8 mg/kg dose-dependently prevented the development of anxiety in BALB/c mice. Chronic intraperitoneal administration of ALM-802 in a dose of 2 mg/kg to alcohol-preferring rats at...

For evaluation of the effect of high-fat diet on the development of diabetic complications, the rats were maintained on standard or high-fat diet. In 3 weeks, diabetes mellitus was modeled by single intraperitoneal injection of streptozotocin. Changes in hematological parameters, physical and biochemical parameters of the urine, and in the development of thermal allodynia were different after 15-week standard and high-fat diets.

The relationship between the appearance of bone metabolism disorders and the onset of steroid-induced osteonecrosis remains unclear. We studied the time course of calcium, phosphorus, osteocalcin, alkaline phosphatase, and mineral density of bone tissue in the subchondral bone of the femoral head of rabbits injected with steroids and attempted to precisely determine the time when disorders in bone metabolism started in animals with steroid-induced osteonecrosis. We detected bone metabolism disor...

We studied the expression of small heat shock proteins HSP10 and HSP27 in left ventricular cardiomyocytes in animals with arterial hypertension, insulin-dependent diabetes mellitus, and their combination. The experiment was performed on 38-week-old male Wistar-Kyoto and 38-57-week-old SHR (spontaneously hypertensive) rats. Insulin-dependent diabetes mellitus was modeled by single parenteral injection of streptozotocin (65 mg/kg). Expression of HSP10 and HSP27 in left ventricular cardiomyocytes w...

The study examined the infradian rhythms in total motor activity and the periods of "freerunning" circadian rhythm in male C57BL/6 mice and European greenfinch Chloris chloris exposed to constant light. In birds and mice, the motor activity was characterized with inphase 4-day-long rhythm. The periods of free-running circadian rhythms in birds and mice were 23 and 25 h, respectively, and they were modulated with 4-day-long periodicity. The maximal deviations in the period of free-running circadi...

We studied association of polymorphic markers Glu298Asp (rs1799983), C774T (rs1549758), and T786C (rs2070744) of the NOS3 gene with the risk of atopic dermatitis. It was found that T786C polymorphic marker of the NOS3 gene is associated with lower risk of erythematosquamous lichenoid atopic dermatitis. A significant association between the homozygous CC genotype in locus 786 of the NOS3 gene and the development of erythematosquamous atopic dermatitis with lichenification was revealed. The homozy...

We studied the relationship between body weight and behavioral characteristics (anxiety, social status, aggressive and exploratory behavior, and sociability) of socially housed adult male cynomolgus macaques. Of the studied parameters, only anxiety showed pronounced relationship with body weight. It is noteworthy that state anxiety demonstrated stronger relationship with body weight than trait anxiety.
