Changes of the electrical characteristics of command neurons of defensive behavior caused by the development of a conditioned situational defensive reflex were studied experimentally under in vitro conditions on preparations of the nervous system of snails. After learning, the membrane and threshold potentials of command neurons LPa3 and RPa3 significantly decreased and excitability of the studied neurons increased.We studied the effect of unstable ubiquitous endocrine disruptors (bisphenol A and triclosan) on the reproductive function of mature male Wistar rats. Animals of both experimental groups received bisphenol A and triclosan (homogeneity>97%) in a dose of 200 mg/kg daily for 2 months with food. The concentrations of disruptors were measured directly in the testicular tissue by gas chromatography with mass spectrometry (GC-MS). In both experimental groups, the concentrations of bisphenol A and triclosan in the testicular tissue significantly differed from the control (intact animals). Animals exposed to bisphenol A significantly differed by sperm parameters (total number, motility, and sperm morphology) from control rats. Animals receiving triclosan significantly differed from control rats only by the number of actively motile spermatozoa and the weight of the testicles.Pharmacokinetics of suppository forms of bacteriophages was studied on male Chinchilla rabbits. Suppositories with various composition of bacteriophages were administered once per rectum to rabbits, and the presence of phage particles was estimated in the blood, urine, and feces over 24 h. Pharmacokinetic study showed that the phages were detected in the blood, urine, and feces at various terms of the experiment irrespective of the size of viral particles, which confirmed the possibility of their systemic effects after rectal administration. Thus, the use of suppository form of bacteriophages can ensure the presence of phage particles even in infection foci that cannot directly contact with the preparation.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 β-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.We studied activities of antioxidant system enzymes in tissues of rats with experimental allergic encephalomyelitis. It was shown that the development of pathology is accompanied by deformation of the neurons and axonal degeneration, intensification of free radical oxidation, exhaustion of the reduced glutathione pool, and multidirectional changes in activities of antioxidant enzymes in rat tissues. The observed imbalance in the antioxidant defense system can be associated with excessive glutathione utilization in the glutathione transferase reaction and different severity of the pathological process in the brain and spinal cord. The received data necessitate the search for compounds that can prevent inhibition of antioxidant system components in order to analyze the possibility of their use in the treatment of multiple sclerosis.The study compared antituberculous efficacy of individual or combined administration of "free" isoniazid and liposomal form of dextrazide (a composition consisted of isoniazid and oxidized dextran) inhaled in standard (15 mg/kg) or low (3 mg/kg) dose. The therapy started 1 month after contamination of outbred ICR male mice with Mycobacterium tuberculosis strain H37Rv. Combined inhalation of liposomal form of dextrazide and isoniazid in the low dose was most effective against mycobacterium tuberculosis due to diminished prodestructive pulmonary effect and a low hepatotoxicity. A minor prodestructive effect of this combination was observed starting from 1.5 month after the onset of therapy (12 inhalations, 2 times a week), and it augmented after 24 inhalations administered during 3 months.BACKGROUNDS AND OBJECTIVES The use of local antibiotic delivery vehicles is common in the management of biofilm-related infections as they provide high concentrations of local antibiotics while simultaneously avoiding complications from systemic toxicity. We present a 100% pure synthetic calcium sulfate hemi-hydrate mixed with 240 mg tobramycin and 500 mg vancomycin per 10 cc mixture for use in revision surgeries of periprosthetic joint infections (PJIs). The purified carrier demonstrates bioabsorbablity, promotion of bone growth, a physiologically favorable pH, and hydrophilicity. Ferrostatin1 These unique properties may alleviate persistent postoperative wound drainage seen in patients with PJI. Our questions consist of two parts (1) does the novel calcium sulfate carrier provide therapeutic concentrations of antibiotic locally that can kill biofilm related infections? (2) Are serum concentrations of antibiotic significant to cause concern for systemic toxicity? METHODS To address these questions, we assayed the elution of antibiotic concentrations obtained from surgical drains and serum among 50 patients in the first 5 postoperative days. RESULTS The elution of vancomycin and tobramycin was greatest on day 1 compared with those concentrations obtained on days 2, 3, 4, and 5; serum concentrations were largely undetectable. Our findings demonstrate that this calcium sulfate preparation provides therapeutic delivery of vancomycin and tobramycin locally at log 2-3 above the minimum inhibitory concentration (MIC), while avoiding toxic serum concentrations. CONCLUSIONS When used in one-stage revision arthroplasties, the bioabsorbable, purified carrier delivers high concentrations of antibiotic while avoiding systemic toxicity.
