A cross-sectional study was carried out in 2016 in the research project No 4/2016. We selected 98 patients aged 40-89 and diagnosed with hypertension. The patients were admitted to Cardiology Clinic One of the University Hospital in Pleven. The study aimed to measure and compare direct and indirect costs of hypertensive patients aged 40-89 years, who were treated with lisinopril and perindopril. We estimated the total and average costs of 50 (51.0%) patients treated with lisinopril and 48 (49.0%) treated with perindopril. Males were 46.4%, and the mean age of the sample was 65.9.0±11.2 years. Data were processed by Statistical Package for Social Science version 19.0 (SPSS.v.19.0). Total costs exceeded amount reimbursed for the clinical path (BGN 420.00) in 64.6% of the patients treated with perindopril and 48.0% of the patients treated with lisinopril. We found that treatment costs within 6-months after discharge were BGN 673.82 in patients treated with lisinopril, as compared to BGN 171.92 reimbursed by the National Health Insurance Fund (NHIF), and BGN 781.18 for those treated with perindopril, compared to BGN 216.33 reimbursed by NHIF. The NHIF reimbursement rate for antihypertensive treatment is insufficient to cover all direct costs. Increased hospital costs and out-of-pocket payments present a significant restriction on access to treatment for arterial hypertension.

The aim of the study was to explore the impact of oxidative stress on frozen seminal plasma in fertile and infertile men by examining the total antioxidant capacity. Patients: Infertile patients from male infertility clinic with various diagnoses and fertile men. Design: Seminal plasma from proven fertile men [n=50] and infertile patients [n=50] were examined for total antioxidant capacity (TAC) level, semen parameters such as morphology, motility and concentration, and DNA integrity test. Interventions: Seminal plasma TAC measurement by luminometric assay using the TAC assay kit, semen analysis parameters, DNA integrity test. Fertile men showed higher TAC values (median and SD): 1201µM (SD±548), as compared with the infertile patients: 831μM (SD±343). The result from sperm morphology of fertile patients showed a mean percentage of 4.8 % (SD±1.68) whereas the percentage in the infertile group was 2.68% (SD ±1.68). The same group of samples, analyzed for DNA damage showed a mean of DFI 10.38% (SD±5.17%) in fertile men and a mean of DFI 17.22% (SD±7.22%) in infertile men. Total antioxidant capacity of the seminal plasma as measured by the luminоmetric assay is a reliable and simple test for diagnosing and management of male infertility.

Leptin inhibits feeding, reduces body weight and increases thermogenesis. Experimental data suggest involvement of GABAergic mechanisms in the regulation of feeding behavior and energy balance. The present study was set to determine the effect of combinations from leptin, GABAB-agonist baclofen and GABAB-antagonist CGP35348 on thermoregulation of male Wistar rats, using in vivo and in vitro experiments. The substances used for in vivo experiments were administered intraperitoneally (i.p.). The measurement of the body temperature was done via thermistor probes (TX8) and monitored on multichannel recorder Iso-Thermex16. In vitro experiments were conducted on rat PO/AH neurons, recorded extracellulary by conventional electrophysiological equipment, using brain slice preparations. The separate intraperitoneal injection of leptin as well as GABAB-antagonist CGP35348 produced significant hyperthermia in rats while the GABAB-agonist baclofen caused a decrease in the core body temperature. The probable synergy between the hyperthermic effects of leptin and GABAB-antagonist did not occur. On the contrary, the effect of this combination was lower as compared to the result of the separate administration of GABAB-antagonist. When leptin was applied just prior to GABAB-agonist baclofen, neither of their separate effects appeared. In vivo effects determined correlated with in vitro changes of firing rate observed in PO/AH neurons. The data from this study provide a new point of view concerning the interactions of leptin and GABA on the level of thermoregulation. These results represent a step forward in understanding the complicated mechanisms involved in thermoregulation.
