    Change in blood glucose level in rats after immobilization

    Get PDF
    Experiments were carried out on male white rats divided into four groups. In group one the blood glucose level was determined immediately after immobilization. In the other three groups, two hours following immobilization, the blood glucose level was determined every 20 minutes for 3 hours 40 minutes by the glucose oxidase method. Preliminary immobilization for 2 hours removed the increase in the blood glucose caused by the stress reaction. By the 2nd hour of immobilization in the presence of continuing stress, the blood glucose level stabilized and varied within 42 + or - 5.5 and 47 + or - 8.1 mg %. Within 2 hours after the immobilization, the differences in the blood glucose level of the rats from the control groups were statistically insignificant

    Perspective materials for drug delivery in the ophthalmic dosage form: a short review of polymers for electrospinning

    Get PDF
    The traditional ophthalmological dosage forms have a low bioavailability, a rapid precorneal clearance and a low corneal permeability. The gelling system or system with a prolonged action (prolonged eye-drops) may be overcome by the application of fibers. An innovative dosage form was described for ophthalmology and perspective drug development. The authors also conducted an overview of the polymers investigated in the production of films or tablets for oral dosage form

    According to official medical statistic data pulmonary diseases are the most frequent pathology in a polyclinic practice. The morbidity level for pulmonary diseases is 23 832 per 100 thousand of adult population in Kostroma region. The hospital admissions number for COPD patients is 800.9; the mortality of COPD is 58.3 per 100 thousand of adults. Eighteen per cent of fatal outcomes took place in COPD patients in hospitals and 82% were registered at home. Long-term oxygen therapy (LTOT) using oxygen concentrators was organized at home for 12 patients with COPD and severe respiratory failure. An average LTOT duration was 6.1 months, mean daily time was 15.25 hours, oxygen flow rate was 2 liters per minute. All the patients demonstrated the improvement in exercise capacity, the reduction of inhaled beta-agonists and oral glucocorticoids doses and hospitalizations numbers.По Π΄Π°Π½Π½Ρ‹ΠΌ ΠΎΡ„ΠΈΡ†ΠΈΠ°Π»ΡŒΠ½ΠΎΠΉ мСдицинской статистики Π±ΠΎΠ»Π΅Π·Π½ΠΈ ΠΎΡ€Π³Π°Π½ΠΎΠ² дыхания Π·Π°Π½ΠΈΠΌΠ°ΡŽΡ‚ 1-Π΅ мСсто Π² структурС заболСваСмости ΠΏΠΎ обращаСмости.

    According to official medical statistic data pulmonary diseases are the most frequent pathology in polyclinics. Near 25,000 hospitalisations and more than 7,000 calls for the ambulance care regard to the pulmonary diseases at Kostroma region. The organisation of medical care for these patients in polyclinics and at home using long-term oxygen therapy and nebulized therapy provides good effect with less expenses.ΠΠ΅ΠΎΠ±Ρ…ΠΎΠ΄ΠΈΠΌΠΎΡΡ‚ΡŒ ΠΎΡ€Π³Π°Π½ΠΈΠ·Π°Ρ†ΠΈΠΈ спСциализированной ΠΏΡƒΠ»ΡŒΠΌΠΎΠ½ΠΎΠ»ΠΎΠ³ΠΈΡ‡Π΅ΡΠΊΠΎΠΉ ΠΏΠΎΠΌΠΎΡ‰ΠΈ Π² ΠΏΠΎΠ»ΠΈΠΊΠ»ΠΈΠ½ΠΈΠΊΠ΅ ΠΈ Π½Π° Π΄ΠΎΠΌΡƒ связана с высокой Ρ€Π°ΡΠΏΡ€ΠΎΡΡ‚Ρ€Π°Π½Π΅Π½Π½ΠΎΡΡ‚ΡŒΡŽ Π±ΠΎΠ»Π΅Π·Π½Π΅ΠΉ ΠΎΡ€Π³Π°Π½ΠΎΠ² дыхания.

    Electrospun formulations of acyclovir, ciprofloxacin and cyanocobalamin for ocular drug delivery

    Get PDF
    Two series of fibers containing the active ingredients acyclovir, ciprofloxacin and cyanocobalamin, and combinations of these drugs, were prepared by electrospinning. One set used the hydrophilic poly(vinylpyrrolidone) (PVP) as the filament-forming polymer, while the other used the slow-dissolving poly(Ξ΅-caprolactone) (PCL). The fibers were found to have cylindrical morphologies, although there was evidence for solvent occlusion with the PVP systems and for some drug particles in the PCL case. The active ingredients were generally present in the amorphous physical form in the case of PVP, but evidence of crystallinity was observed with PCL. The existence of intermolecular interactions between the drugs and polymers was proven using simple molecular modeling calculations. Drug release from the various fibers was tested in a validated in vitro outflow model of the eye, and the fiber formulations found to be capable of extending drug release. We thus conclude that electrospun matrices such as those prepared in this work have potential for use as intravitreal implants

    Long-term oxygen therapy (LTOT) improves survival of patients with chronic obstructive pulmonary disease (COPD) having severe respiratory failure and chronic hypoxemia. In our study 51 patients received LTOT at home via concentrators (34 males, the mean age, 65.5 Β± 7.8 yrs; 17 females, the mean age, 62.8 Β± 4.1 yrs). Of them, 37 (72.5 %) survived 6-year period and 14 died (13 males and 1 female). Causes of death were acute respiratory viral infection (in 1 patient), insult (in 1 patient), chronic heart and lung failure (in 12 patients). Survival of patients with chronic restrictive pulmonary diseases was not longer than 3 years. A control group included 45 COPD patients with severe respiratory failure not receiving LTOT (30 males, the mean age, 66.3 Β± 8.5 yrs; 15 females, the mean age, 69.1 Β± 4.6 yrs). Of them, 16 survived 6 years and 29 died (5 females, the mean age, 72.6 Β± 3.6 yrs, 24 males, the mean age, 67.8 Β± 5.2 yrs). So, LTOT at home improves survival of COPD patients with severe respiratory failure.Π”Π»ΠΈΡ‚Π΅Π»ΡŒΠ½Π°Ρ кислородотСрапия Π½Π° Π΄ΠΎΠΌΡƒ (Π”ΠšΠ’) ΡƒΠ²Π΅Π»ΠΈΡ‡ΠΈΠ²Π°Π΅Ρ‚ Π²Ρ‹ΠΆΠΈΠ²Π°Π΅ΠΌΠΎΡΡ‚ΡŒ Π±ΠΎΠ»ΡŒΠ½Ρ‹Ρ… хроничСской обструктивной болСзнью Π»Π΅Π³ΠΊΠΈΡ… (Π₯ΠžΠ‘Π›) с явлСниями тяТСлой Π΄Ρ‹Ρ…Π°Ρ‚Π΅Π»ΡŒΠ½ΠΎΠΉ нСдостаточности ΠΈ хроничСской гипоксСмии.
