Aim. To evaluate the common carotid artery (CCA) intima-media complex thickness (IMT) and the presence of atherosclerotic plaques (ASP) in young people with abdominal obesity who don’t have metabolic syndrome and those who have it, as well as a link between fat depots (perivascular, visceral, subcutaneous, epicardial) and CCA IMT. Materials and methods. The study included 145 people aged 18-45 years. They were divided into 3 groups: group 1 (n=18) - healthy volunteers (control group), group 2 (n=48) - patients with abdominal obesity and no more than one additional risk factor (metabolically healthy) and group 3 (n=79) - patients with metabolic syndrome. In persons included in the study the following parameters were measured: the height, weight, body mass index, waist circumference, fasting blood glucose, glucose tolerance, uric acid, lipid profile, insulin and the insulin resistance index (HOMA-IR). They also were given a 24-hour blood pressure monitoring, and an evaluation of CCA IMT, a presence of ASP in the carotid arteries and a maximum degree of internal carotid stenosis was performed using the duplex scan of brachiocephalic arteries. Computed tomography (Aquilion One Vision Edition, Toshiba, Japan) with determining subcutaneous, visceral, perivascular, epicardial fat was performed, and the ratio of subcutaneous to visceral fat was calculated. Results. Significant differences in mean CCA IMT were revealed only between persons of group 1 and group 3 (p=0.025), while the median of IMT were within normal ranges (group 1: 0.49 [0.46; 0.56]; group 2: 0.53 [0.49; 0.59]; group 3: 0.56 [0.52; 0.62]). Significant differences in a distribution of individuals with increased IMT between groups were also not revealed. However, the proportion of individuals with ASP was significantly higher in group 2 compared with group 1 (p

Abstract Background Salt restriction is essential for a healthy diet, especially for patients (pts) with cardiovascular diseases. Pts education has a potential to promote healthier dietary patterns. Purpose To assess the impact of 2 preventive counselling programs with subsequent remote support resulted after hospitalization on salt intake in pts with coronary artery disease (CHD). Methods A prospective randomized parallel-group study in hospitalized nonsurgical pts with confirmed stable CHD and concomitant abdominal obesity. Most hospitalizations were due to elective percutaneous coronary intervention. Pts were randomized (1:1:1) into 3 groups. Before discharge, Groups 1 and 2 received comprehensive counselling with focus on diet followed by remote counselling by phone (Group 1) or via text messages (Group 2). Remote counselling was delivered weekly (Months 1–3) and then monthly (Months 4–6). Group 3 received standard advice only. Self-reported salt intake was assessed by consumption of sodium-reach foods such as sausages, pickles and by adding salt to cooked foods. Results A total of 120 pts (mean age±SD, 57,75±6,25 years, men, 83.4%) were enrolled. The Table presents self-reported dietary habits at baseline and at 12 months. At 1 year, significant improvements of relevant dietary habits vs control were seen in both intervention groups. Group 1 Group 2 Group 3 (Control) Group 1 vs 3, Group 2 vs 3, (n=40) (n=40) (n=40) P for change from baseline P for change from baseline Pts adding salt to cooked foods at least sometimes   Baseline 87.5% 90.0% 85.0%   At 12 months 25.0%** 10.0%** 89.5% <0.01 <0.01 Pts avoiding pickled vegetables   Baseline 17.5% 20.0% 15.4%   At 12 months 62.5%* 77.5%** 7.9% <0.05 <0.01 Pts avoiding wurst, sausages, smoked meats   Baseline 0.0% 10.0% 7.5%   At 12 months 77.5%** 87.5%** 2.6% <0.01 <0.01 *p<0.05, **p<0.01 vs baseline within group. Conclusion Pre-discharge preventive counselling with subsequent remote support in coronary patients with abdominal obesity resulted in significant improvement of dietary habits in terms of salt and high-sodium foods intake.

Aim. To study the effect of hyperglycemia on the total surface charge of the erythrocyte membrane (SCEM) in patients with metabolic syndrome (MS).Material and methods. 112 MS patients were examined (45 men and 67 women) (mean age 61.4±7.2 years, average MS duration 8.7±5.2 years). The level of SCEM was determined by adsorption of a positive cationic dye (cationic blue O) on the surface of the plasma membrane of erythrocytes to completely neutralize their negative charge, followed by photometry of the solution and calculation of the number of charges on the cell surface of erythrocytes.Results. In the main group of patients with MS, abdominal obesity was observed in 100% of patients, arterial hypertension – in 73%, hyperglycemia – in 75%, dyslipidemia – in 80%. The level of glycated hemoglobin (HbA1c) was determined in all patients with MS, which was 7.3±1.9%. Patients with MS were conditionally divided according to the level of HbA1c into 2 groups (group 1 – HbA1c from 6.6 to 7.8%, group 2 – more than 7.8%). In MS patients with hyperglycemia, the SCEM values were significantly lower than in the group of patients without hyperglycemia (1.58±0.05×107 and 1.64±0.03×107, respectively; p=0.001)., Significant negative correlations between SCEM and the fasting blood glucose level, hyperglycemia duration, HbA1c level were found in patients with MS.Conclusion. SCEM indices reliably depended on the presence, severity and duration of hyperglycemia, which indicated the effect of impaired carbohydrate metabolism on the state of electric charge of erythrocyte membranes and, therefore, on the mechanisms of microvascular blood flow, thereby contributing to the development of vascular changes in patients with MS.

Background The aim of this study was to evaluate the postoperative morphine-sparing effects and reduction in pain and secondary mechanical hyperalgesia after preincisional or postincisional epidural administration of a local anesthetic and an opioid compared with a sham epidural control. Methods Patients undergoing major gynecologic surgery by laparotomy were randomly assigned to three groups and studied in a double-blinded manner. Group 1 received epidural lidocaine and fentanyl before incision and epidural saline 40 min after incision. Group 2 received epidural saline before incision and epidural lidocaine and fentanyl 40 min after incision. Group 3 received a sham epidural control (with saline injected into a catheter taped to the back) before and 40 min after incision. All patients underwent surgery with general anesthesia. Results One hundred forty-one patients completed the study (group 1, n = 45; group 2, n = 49; group 3, n = 47). Cumulative patient-controlled analgesia morphine consumption at 48 h was significantly lower (P = 0.04) in group 1 (89.8 +/- 43.3 mg) than group 3 (112.5 +/- 71.5 mg) but not group 2 (95.4 +/- 60.2 mg), although the hourly rate of morphine consumption between 24 and 48 h after surgery was significantly lower (P &lt; 0.0009) in group 1 (1.25 +/- 0.02 mg/h) than group 2 (1.41 +/- 0.02 mg/h). Twenty-four hours after surgery, the visual analog scale pain score on movement was significantly less intense (P = 0.005) in group 1 (4.9 +/- 2.2 cm) than group 3 (6.0 +/- 2.6 cm) but not group 2 (5.3 +/- 2.5 cm), and the von Frey pain threshold near the wound was significantly higher (P = 0.03) in group 1 (6.4 +/- 0.6 log mg) than in group 3 (6.1 +/- 0.8 log mg) but not group 2 (6.2 +/- 0.7 log mg). Conclusions Preincisional administration of epidural lidocaine and fentanyl was associated with a significantly lower rate of morphine use, lower cumulative morphine consumption, and reduced hyperalgesia compared with a sham epidural condition. These results highlight the importance of including a standard treatment control group to avoid the problems of interpretation that arise when two-group studies of preemptive analgesia (preincisional vs. postsurgery) fail to find the anticipated effects.

In medical sciences, toxicity is an area wherein extensive studies have been carried to improve the diseases as well as to prevent. So, there is a high requirement for novel and improved alternative therapeutic strategies to manage diseases. The liver is the largest gland in the body, which executes several important mechanisms; it stores minerals and vitamins and releases them in periods of need. The main aim of this study was to give a closer insight into potent non- toxic compounds that is capable of modifying the responses. Animals were divided into five equal groups viz control (Group 1), administered with food and water ad libitum, (Group 2) administered with olive oil, (Group 3) administered with zingerone, (Group 4) administered with concanavalin A, (Group 5) administered with cyclosporine A followed by zingerone. Our results revealed significant changes in liver marker enzymes and liver histology of zingerone treated rats when compared to control rats.  A corollary, zingerone has no toxic effect on hepatocytes and was found to be safe at a dose of 10mg/kg b wt and also ameliorates hepatotoxicity.

This study was designed to evaluate antischistosomal activity of Nitazoxanide (NTZ) in Schistosoma mansoni-infected mice compared to Praziquantel (PZQ). Fifty four infected mice were recruited into 3 groups, each of 18 mice. Group 1 was infected non-treated control. Group 2 was infected and then treated with PZQ 500 mg for two days, and group 3 was infected and treated with NTZ 100 mg/kg for seven days. Efficacy of drugs was assessed by Parasitological, and scanning electron microscopic studies. PZQ reduced (4.9%, 22.5% and 50.7%) of faecal eggs, (22%, 22.6% and 55.1%) of intestinal eggs, (20.4%, 44.3% and 46.7%) of hepatic egg counts and (27%, 45.1% and 64.9%) of total worm load whereas, NTZ reduced (4.9%, 22.5% and 50.7%),of faecal eggs, (22%, 22.6% and 55.1%) of intestinal eggs ,(20.4%, 44.3% and 46.7%) of hepatic egg counts and (27%, 45.1% and 64.9%) of total worm load at 1, 2 and 4 WPT, respectively. The percentages of dead eggs were more than 80% after PZQ treatment and only 30% after NTZ at 4 WPT. PZQ showed extensive tegumental damages in male and female worms more than NTZ at 2 WPT. Our findings concluded that Nitazoxanide showed weaker antischistosomal activity in animal models than praziquantel.

SummaryObjective: To investigate the effects of various activation methods on freeze–thawed rabbit oocytes developmental potential. Methods: Rabbit oocytes were vitrified by cryoleafs and cryoprotected with ethylene glycol and propanediol. After thawing, the oocytes were fertilized by intracytoplasmic sperm injection (ICSI). Surviving oocytes after ICSI were divided into five groups at random. Group 1: Oocytes (n = 30) activated 1 h after ICSI by calcium ionomycin (I0634); Group 2: Oocytes (n = 26) activated by strontium chloride an hour after ICSI; Group 3: Oocytes (n = 33) activated by I0634 twice; Group 4: Oocytes (n = 28) were activated by strontium chloride twice; Control Group: Inactivated oocytes (n = 39). Blastocysts derived from each group were transplanted to recipient rabbits. Results: Rates of fertilization, cleavage and blastocyst formation of Group 3 were higher than those of Group 1 and Group 2 (81.8% vs 33.3% vs 53.8%, 54.5% vs 16.7% vs 26.9%, p < 0.05; 15.2% vs 3.3% vs 7.7%, p > 0.05). The rabbit transplanted with embryos derived from Group 3 became pregnant. Embryos derived from double activation could implant into endometrium. Conclusion: Double activation may increase freeze–thawed oocytes developmental potential. After activation, oocytes cleavage velocity may be faster than that of oocytes without activation.

Abstract Background: Premature ovarian failure is among the most important side effects of chemotherapy during reproductive period. Preserving ovarian function is gradually gaining importance during oncologic treatment. The present study aims to investigate the potential of melatonin to protect from cisplatin-induced ovarian toxicity in rats. Twenty nine female rats were divided to three groups: Saline control group (Group 1), cisplatin group (Group 2), and cisplatin+melatonin group (Group 3). While the rats in Groups 2 and 3 were administered 5 mg/kg single dose of cisplatin via intra-peritoneal (IP) route, the rats in Group 3 were started on melatonin (20 mg/kg IP) before cisplatin administration and continued during 3 consecutive days. Ovaries were removed one week after cisplatin administration in all groups. Blood samples were obtained before the rats were decapited. Histological evaluation, follicle count, and classification were performed. TAp63 mRNA expression was evaluated using mRNA extraction and real-time polymerase chain reaction (PCR) method. Serum estradiol (E2) and anti-mullerian hormone (AMH) values were measured with enzyme immune-assay technology. Results: While primordial follicles were seen to decrease in Group 2 as compared to Group 1 (p:0.023), primordial follicle count was observed to be preserved significantly in melatonin group as compared to Group 2 (p:0.047). Moreover, cisplatin-induced histo-pathological morphology was preserved in favor of normal histology in melatonin group. A significant difference was not observed between groups with regard to mean serum AMH and E2 values (p:0.102 and p:0.411, respectively). While TAp63 gene expression significantly increased in Group 2 as compared to control group (p:0.001), we did not detect a statistically significant difference in cisplatin+melatonin group, although gene expression decreased (p:0.34). Conclusion: We conclude that concurrent administration of melatonin and cisplatin may protect from ovarian damage.
