Objective Earlier studies have reported that a decrease in exercise capacity might indicate endothelial dysfunction. However, the effects of improvement of endothelial functions on exercise capacity have not been evaluated. The aim of the present study is to investigate the effects of nebivolol on flow-mediated dilatation (FMD), and on the exercise capacities of the patients with slow coronary flow (SCF). Methods The study population included 25 subjects with SCF (Group 1) documented by the thrombolysis in myocardial infarction (TIMI) frame count, and 25 control group (Group 2) subjects with normal coronary angiography, for a total of 50 subjects who underwent coronary angiography due to several indications and had no coronary lesion. The TIMI frame count (TFC) values of the subjects in Group I for left anterior descending artery, right coronary, and circumflex coronary artery were 61.8 ± 30.6, 37.2 ± 17.4, and 34.6 ± 17.4, respectively. All the subjects received nebivolol 5 mg/day. Results At the end of the first month of FMD, the mean exercise duration (MED) and the Duke Scores of the patients with SCF were significantly higher than the baseline values. However, the values by the sixth month did not differ from that at the first month. Although a numerical improvement compared to the baseline values was observed for the subjects in Group 2 by the measurements at the end of the first and the sixth month, this difference was not statistically significant. Conclusions Nebivolol treatment increases FMD in the subjects with SCF. The difference in the exercise parameters of these subjects is particularly dramatic, and such an outcome may indirectly indicate long-term improvement in endothelial function.

Purpose: To study the effect of anterior capsule polishing during phacoemulsification on the incidence of post operative YAG laser capsulotomy. Method: A retrospective controlled study of 159 patients who underwent uncomplicated phacoemulsification with anterior capsular polishing between October 1998 and March 2000. 169 age matched patients who underwent phacoemulsification but without anterior capsule polishing served as controls. Main outcome measure: Incidence of visually significant YAG capsulotomy, which improved the Snellen acuity for more than 1 line or at least 1 line with subjective improvements in symptoms. Results: 2.51 % of patients with anterior capsular polishing (Group 1) had YAG capsulotomy compared to 7.1% of patients in control group at one year. However, after two years, 11.3% of patients in Group I had YAG capsulotomy compared to 12.4% in Group 2. Conclusion: Anterior capsular polishing during cataract surgery may delay the opacification of posterior capsule during the early postoperative period. But does not decrease the incidence of YAG capsulotomy after two years.

An extension of McGuire's inoculation theory, from the area of cultural truisms to the realm of controverted beliefs, was investigated by manipulating previous attack as part of a group discussion situation in which actual defense of an issue was considered essential for having an inoculating effect. Results (p < 0.05) favored the main hypothesis when group I (requiring defense in response to a written verbal attack) was compared with the control group, but there were no significant differences between group I and group 2 (requiring discussion but no defense since there was no verbal attack).

Abstract Introduction The mechanisms mediating benefits of enhanced external counterpulsation (EECP) are disputable since the origin of the method. One of the possible explanations presumes increased diastolic flow leads to changes of endothelial function and plays a crucial role in alleviating the symptoms of angina and heart failure; the exact mechanisms of action are still under investigation, though the endothelial hypothesis possesses strong evidence. Purpose To reveal the impact of repeated EECP on endothelial function of patients undergoing cardiac rehabilitation program after myocardial infarction (MI) and to identify possible clinical implications of these changes. Methods The randomized sham-controlled study included 46 patients with coronary artery disease who suffered from ST-elevation MI (STEMI) 4–8 weeks prior to enrollment in 2017–2018. All patients had undergone primary PCI due to STEMI in 2–24 hours after the event. Echo parameters, exercise tolerance and the levels of ADMA and nitric oxide (NO) metabolites (total content, nitrite and nitrate) in plasma were determined at the enrollment stage and at three month follow-up. Patients were randomized and given 35 h of active counterpulsation (main group, n=24) or inactive counterpulsation (control group, n=22) over a six-week period after enrollment. Results The analysis showed no significant difference between groups at baseline: mean ejection fraction was 46% in the main group and 45% in the control group, no difference in exercise tolerance. The mean characteristics of endothelial function at baseline were similar in both main and control groups: total NO metabolites (17.3±2.14 μmol/L vs. 19.6±3.31, p=0. 42), nitrite level (0.76±0.17 μmol/L vs. 0.75±0.21, p=0. 36), ADMA level (0.78±0.15 μmol/L vs. 0.81±0.20, p=0. 22). At three month follow up 41,7% of patients of the main group showed improvement of one class of NYHA classification compared to 22,7% in the control group (U=122.3, p=0.012), agreed with improved exercise tolerance: average +2.8 MET in main group in opposite to only +0.8 MET in the controls (U=104, p=0.007). Control group demonstrated no significant dynamics of NO metabolites concentration comparing to baseline values, while in the main group there was a significant decrease of ADMA – 0.57±0.11 μmol/L (Z=r=−2.46, p=0.013) and increase of nitrite level – 1,12±0. 18 μmol/L (Z=r=−2.57, p=0.011), with no changes in total NO metabolites content. The further analysis demonstrated strong correlation between exercise capacity gain and ADMA decrease (R=r=−0.52, p=0.008) or nitrite elevation (R=0.48, p=0.012), with ADMA/nitrite ratio being the strongest predictor of clinical improvement (R=0.68, p=0.002). Conclusion Active EECP improves exercise capacity and heart failre symptoms in patients undergoing post-MI rehabilitation, with those effects being associated with endothelial function enhancement.

Objectives. This study is aimed at investigating alterations in liver volume during obstructive jaundice in rat liver. Materials and Methods. Thirty-six rats were divided into four groups. Abdominal tomography was performed for baseline volumetric analyses. The main bile ducts were ligated (BDL). Volumetric analyses were repeated 3 days after BDL in group 1, 7 days after BDL in group 2, 15 days after BDL in group 3, and 25 days after BDL in group 4, and total hepatectomy was performed in all animals. Control group () was created with the rats that died before bile duct ligation. Results. There was no difference found in liver volume in group 1 compared to control animals. The liver volume was increased 7 days after BDL (). It was increased up to 60% of baseline values 25 days after BDL (). Wet liver weights of animals were also increased compared to control group. Liver weights were increased up to 40% percent of baseline values in group 4 (). Conclusions. Liver volume and weight were increased after BDL. Liver surgery in patients with huge liver mass is generally associated with significant difficulty. The surgeon should be aware of the time-dependent alteration in liver volume after obstructive jaundice.

Coronary Slow Flow

Background: It has been reported that coronary slow flow (CSF) is associated with acute myocardial infarction, ventricular tachycardia, ventricular fibrillation, and even sudden cardiac death. Although studies concerning the etiopathogenesis of CSF are scarce, diffuse atherosclerosis and endothelial dysfunction are thought to play important roles. It has been suggested that a high plasma thrombomodulin (TM) level seems to play an important role in the pathogenesis of atherosclerosis and endothelial dysfunction. Objectives: We hypothesized that a high plasma TM level might be associated with CSF and aimed to research the relationship between plasma TM level and CSF. Methods: Fifty-two CSF patients with angiographically proven CSF and 44 cases with normal coronary flow were included in this study. Coronary flow velocity was determined by the thrombolysis in myocardial infarction (TIMI) frame count method. Plasma TM levels were measured in all the study subjects. Results: Plasma TM levels were significantly higher in the CSF group compared to the control group (3.9 ± 0.5 vs. 3.6 ± 0.3 ng/mL, p = 0.01). There was a positive relationship (r = 0.31, p = 0.002) between plasma TM level and mean TIMI frame count (TFC). Factors associated with mean TFC were plasma TM level (β = 0.206, p = 0.038) and red cell distribution width (β = 0.088, p = 0.009) in multiple linear regression analysis. Conclusions: Patients with CSF have a higher plasma TM level, and this may play an important role in the pathogenesis of CSF. An elevated plasma TM level may be a predictor of CSF. Future studies are needed to confirm these results.

Abstract: Introduction and aim: The study compares the antibiotic prophylaxis combined with postoperative antibiotic therapy to preoperative chlorhexidine rinse combined with postoperative antibiotic therapy in preventing complications after surgical removal of a mandibular third molar. Method: 71 healthy patients in four groups were enrolled in the study: I. prophylactic dose of 2000 mg of amoxicillin clavulanate, continued with amoxicillin clavulanate postoperatively; II. prophylactic dose of 600 mg of clindamycin, continued with clindamycin postoperatively; III. prophylactic chlorhexidin rinsing, continued randomized amoxicillin clavulanate or clindamycin postoperatively; IV. control, with clindamycin postoperatively. Results: The pain was smaller in the prophylaxis groups. Alveolitis occurred only in the control group: 2 patients. Wound opening occurred in 22,2 % in group IV., 14,2 % in group II, 10 % in group I., 5 % in group III. Conclusion: We consider completing the indicated postoperative antibiotic prescription with antibiotic or antiseptic prophylaxis. Chlorhexidin prophylaxis could have the same positive effect. Orv.

Background: Despite global warming and the improvement of personal protective equipment against unfavorable climatic factors, cold remains an important environmental challenge for humans. The aim of the work was to reveal the peculiarities of the dynamics of cardiovascular parameters in humans with short-term, whole-body exposure to cold air, depending on the parameters of voluntary attention. Methods and Results: The study involved 28 healthy male volunteers aged between18 and 21 years, born and living in Arkhangelsk. Testing to assess sustained attention parameters using the Toulouse-Pierón Attention Test with the measurement of the index of accuracy (C, units) (the ability to voluntary concentration) and processing speed (V, units), had been previously performed. Subsequent stages of the study included recording the studied parameters before (Stage 1), during 10-minute exposure to the cold air (Stage 2), and 5 minutes after cold exposure (Stage 3). The registration of indicators in Stages 1 and 3 was carried out indoors at an air temperature of +20 °C. The registration of indicators in Stage 2 was carried out in a cold chamber at -20 °C. Determining the body temperature in the ear canal (Tear, °C) and on the skin of the dorsum of the right hand (Tskin, °C) was performed using a B.Well WF-1000 medical electronic infrared thermometer. Parameters of blood pressure (SBP and DBP) and heart rate variability (HRV) were evaluated. As a result of cluster analysis, 2 groups were identified: Group 1 (n=14) and Group 2 (n=14). In Group 2, the index V was significantly lower than in Group 1(P=0.02). In Group I, Tskin in Stage 1 was significantly higher than in Group 2 (P=0.03). In Stage 2, Tskin decreased in both groups, but lower Tskin values (P=0.001) were recorded in Group 2 than in Group I. In Stage 2, there was a statistically significant increase in SBP in Group 2 (P=0.01). In Group 1, initial SDNN and all HRV spectral indices were significantly higher than in Group 2. In Stage 2, there was a significant increase in SDNN in both groups. However, in Group 2, we found a statistically significant increase in VLF in Stage 2 (P=0.01), while in Group I this indicator remained unchanged. In Stage 3, HRV parameters in Group 1 recovered to baseline values, while in Group 2, HRV parameters remained elevated relative to baseline values. Conclusion: Individuals with high processing speed and preserved attention span have higher vagal activity and skin temperature. When such individuals are exposed to cold, they experience a moderate increase in BP and baroreflex response. In persons with a reduced speed of information processing but with sufficient accuracy of attention, there is a more pronounced mobilization of regulation resources on the part of the cardiovascular, neurovegetative systems to maintain the core temperature of the body.
