Annotation. The study of the problem of preeclampsia is still relevant because it is one of the most common complications of pregnancy and is one of the causes of maternal mortality, ranking second after obstetric bleeding. Perinatal mortality rates vary widely and depend on the severity and duration of late preeclampsia. The aim of the study was to investigate the histological aspects of placental complex remodeling in patients whose pregnancy was complicated by late preeclampsia on the background of metabolic syndrome. Women, pregnancy complicated by late gestosis on the background of metabolic syndrome, were divided into two groups: patients of group I received standard protocol therapy group (31 women), women of group II received preventive, modified, pathogenetically justified therapy – protocol treatment + vitamin D in dose of 2000 IU per day, L-arginine, calcium, magnesium sulfate and salicylates 1 sachet for 10 days (38 patients), group III consisted of 40 women whose physiological pregnancy was without complications and extragenital pathology. The obtained histological specimens were examined using a Nikon Eclipse Ci-E light microscope. The algorithm of histological examination was regulated by the generally accepted protocol of pathological examination of manure. In the first study group there were histological changes, which should be regarded as morphological markers of functional disorders in the system “mother-placenta-foetus”, accompanying late preeclampsia. Metaplasia of the cylindrical epithelium of the foetal surface into a multi-layered flat one was observed in the placental amnion, and in some places increased proliferative activity of epitheliocytes was observed, which formed plaque-like structures and growths. In the second study group, which received a modified treatment, the tissue structure of the manure was also characterized by deviations from the histological picture of the control group. However, the intensity and prevalence of pathological changes were significantly lower than in the first study group. In most of the studied histological sections, the cell structure of the amniotic epithelium was preserved, desquamation was not observed. Circulatory disorders in the villous chorion were present, but the structure of most vessels remained unchanged. Based on the results of histological examination, it can be concluded that a comprehensive, modified therapy of late preeclampsia on the background of metabolic syndrome, allows you to normalize the structure of the placenta.

Irisin is a new myokine that is suspected to influence metabolic syndrome (MetS). However, there is a great controversy with respect to its level in cases of MetS and its correlation with different metabolic parameters. The present study assesses irisin levels in MetS patients and studies its relationship to metabolic and liver functions to evaluate the possible role of the liver in regulation of this level. Sixty subjects were included in this experiment, who were divided into 3 groups: group I (normal control), group II (MetS patients with normal liver enzymes), and group III (MetS with elevated liver enzymes and fatty liver disease). Serum irisin levels showed significant increases in groups II and III compared with group I, and significant increases in group III compared with group II. Also, irisin levels were positively correlated with body mass index, serum triglycerides, homeostatic model assessment of insulin resistance index (HOMA-IR), and liver enzymes. We concluded that serum irisin levels increased in patients with MetS, especially those with elevated liver enzymes, and had a positive correlation with parameters of lipid metabolism and glucose homeostasis with the possibility of hepatic clearance to irisin.

Objective: Insulin resistance (IR) means a reduced ability of insulin to stimulate glucose utilization. IR is related to cardiovascular disease (CVD) risk as the IR forms the basis for atherogenesis and acts as a major risk factor for atherosclerotic CVD. Methods: Total of 195 participants were recruited divided into three groups based on the presence of metabolic abnormalities as control Group I (with <3 components of metabolic syndrome [MS]), MS group as Group II (with any 3 components of MS), and severe MS as Group III (with more than three components of MS). Results: Results showed that fasting blood sugar (FBS) and glycated hemoglobin showed a significant difference between the groups (p<0.001), whereas fasting insulin and IR were higher in severe MS which showed statistically significant difference (p<0.001) in comparison with control and MS group. Conclusion: IR is one of the principal factors for the development of MS and further threw light that the increase in the IR level proportionately increases the severity of MS.

BACKGROUND: Hydroxychloroquine (HCQ) is used in the treatment of malaria and rheumatoid arthritis for a long time. Its effects on inflammation and immune modulation were noted. AIM: This study aims to investigate the effects of HCQ in fructose-induced metabolic syndrome and to explore its possible mechanisms. METHODS AND MATERIALS: Sixty male Sprague-Dawley rats were divided into Group I (negative control), Group II fed on high-fructose diet, and Group III fed on high fructose and subdivided into Group III-a (HCQ 50 mg/kg), Group III-b (HCQ 100 mg/kg), Group III-c (HCQ 200 mg/kg), and Group III-d (metformin 100 mg/kg). Body weight, blood glucose, liver enzymes, and lipid profile were measured. Insulin level, homeostatic model assessment (HOMA), soluble-intercellular adhesion molecule, and vascular cell adhesion molecule were assayed. Tumor necrosis factor (TNF)-α, adipokines (leptin, resistin, and adiponectin), and histological examination of pancreas were assessed. RESULTS: HCQ induces good effects on lipid profile and improves significantly HOMA, endothelial stress markers, and adiponectin, and reduces leptin and TNF-α levels. In addition, significant improvement in structural changes was noted in pancreas with different doses of HCQ. CONCLUSION: Favorable effects of HCQ in fructose-induced metabolic syndrome are promising and can be used early in those at risk of diabetes.

Purpose: To improve the effectiveness of treatment of patients with locally advanced rectal cancer (LARC) stage T3(MRF+)-4N0-2M0 by developing a new strategy of therapy. Material and methods: The study included 414 patients with LARC. Control group I included 89 patients who underwent neoadjuvant CRT 52–56 Gy with capecitabine. Control group II included 160 patients, underwent neoadjuvant CRT 52–56 Gy with capecitabine and oxaliplatin once a week, during the course of RT. Study group III - 165 patients. This group combined neoadjuvant CRT 52–56 Gy with capecitabine and additional consecutive courses of chemotherapy (CT) in the CapOx mode. This group, depending on the variant of chemotherapy, was divided into 2 subgroups: subgroup IIIa included 106 patients with consolidating CT (after CRT); subgroup IIIb included 59 patients who underwent "sandwich" treatment. Therapy consists of conducting 1 or 2 courses of induction CT (up to CRT) in the CapOx mode and 1 or 2 courses of consolidating CT in the CapOx mode with an interval of 7 days. In the interval between the courses of drug therapy, prolonged CRT was performed. According to the results of the control examination, further treatment tactics were determined. Results: IComplete therapeutic pathomorphosis in the tumor was significantly more frequently registered in patients in the study group III (17.5 %; p=0.021) compared to the control groups: in I – 8.0 % and II – 8.3 %. In total, relapses in the study were registered in 34 (8.3 %) of 410 patients. A comparative analysis of patients in the control groups (I and II) of treatment did not determine significant differences in the development of relapses (11.4 % vs. 10.8 %, respectively; p=0.884). When analyzing the subgroups (IIIa and IIIb) of the study group, there were also no significant differences in the development of relapses (4.8 % vs. 3.4 %; p=0.676). In the present study, long-term metastases at various times after treatment were diagnosed in 100 (24.4 %) of 410 patients. All metastases occurred at a median follow-up of 20.9 months (4 to 46 months). Metastases were significantly less frequent in patients in group III (18.3 %) compared to group I (31.8 %; p=0.015) and II (26.6 %; p=0.037). There were no significant differences between patients in group I and II (p=0.382). The analysis of the treatment subgroups of the study group (IIIa and IIIb) did not determine significant differences in the development of metastases (19.1 % vs. 17.0 %; p=0.456). The overall five-year survival rate in patients in group III was 90.5 %, in group I – 71.8% and in group II – 78.3%. Five-year relapse-free survival in patients in the study groups was: III – 71.5%, I – 56.9% and II – 65.6%, respectively. Conclusion: The shift in the focus on strengthening the neoadjuvant effect on the tumor and the improvement of approaches to drug therapy regimens allowed to significantly increase the relapse-free survival in this category of patients.

Abstract To study the therapeutic effect of Armillarisin A on patients with ulcerative colitis (UC) and on serum IL-1β and IL-4, sixty patients with UC were randomly divided into three groups: Armillarisin A treatment group (Group I), Armillarisin-combined hormone therapy group (Group II), and hormones treatment as the control group (Group III). Patients in Group I received Armillarisin A 10 mg enema in 100 ml saline. Patients in Group II received Armillarisin A 10 mg and dexamethasone 5 mg enema in 100 ml saline. Patients in Group III received only dexamethasone 5 mg enema in 100 ml saline. The therapeutic efficacy and serum levels of IL-4 and IL-1β were observed. After 4 week treatment, the total effective rates were 90.0 % in Group I and 95.0 % in Group II. Both are higher than it in control group, which was 70.0 %. The serum levels of IL-4 in Groups I and II were significantly higher than it in control group. Compared to IL-4 levels before treatment, the levels of IL-4 after treatment were significantly higher in both Groups I and II. The serum levels of IL-11β were significantly decreased in Groups I and II in comparison to it in control group. Compared to the levels of IL-1β before treatment, the levels of IL-1β were significantly decreased. Armillarisin A shows a significant effect in treating UC. It helps increase IL-4 and lower IL-1β and the mechanism may be related to the body’s immunity regulation.

It is anticipated that Japanese quail /Coturnix coturnix japonica/ will provide animal proteins in long term space flights. Consequently this species of birds is of research interest of international space program INTERCOSMOS. In the year 1987 we reported on an experiment /2/ in which the effect of chronic acceleration of 2 G hypergravitation, the hypodynamy and the simultaneous effect of chronic acceleration and the location in the centre of the turntable of the centrifuge on the protein fractions in skeletal muscles was studied. The ultrastructure of the heart muscle was now in this experiments examined as well.Japanese quail cockerels, aged 48 days were exposed to 2 G hypergravitation /group IV/ in a 6,4 m diameter centrifuge, to hypodynamy /group III/ and their combination /group V/, respectively for 6 days / Fig.1/. The hypodynamy in group III was achieved by suspending the birds in jackets without contact the floor. The group II was located in the centre ofthe turntable of the centrifuge. The control group I. was kept under normal conditions. The quantitative ultrastructure of myocard was evaluated by the methods of Weibel/3/ - this enables to determine the number, relative size and volume of mitochondria volume of single mitochondria, defficiency of mitochondrial cristae and volume of myofibrils.

The article presents the comparative analysis of the state of the cervix in women with endometrial polyps and micropolyps. Patients and methods. The study involved 130 patients aged 18-35 years: 70 patients with endometrial polyps (group I), 30 patients with micropolyps (group II) and 30 patients of the control group (group III). Results. According to the anamnesis of women in the I group were significantly more frequent diseases of the cervix, which corrected physical surgery methods, in particular cryodestruction. In group II, the representatives of these indicators were similar to healthy. Normal colposcopic picture met significantly less frequently in patients and I, and II group. The differences in the incidence of HPV high oncogenic risk in all groups were not statistically significant. Conclusion. Destructive methods used in the detection of any changes in the cervix are often overly aggressive, form scars and contributing to inflamaciones process. In the chain of events leading to the formation of PE, cervical pathology and its correction can take the basic place. Key words: endometrial polyp, micropolyps, chronic endometritis, uterine cervix, colposcopy.

The present study was conducted to investigate the efficacy of Ovsynch and Ovsynch plus protocol in postpartum (day 60) Sahiwal cows (n=18). Animals were randomly divided into three equal groups, viz., Ovsynch group Ovsynch plus group and Control group. Animals of group I (n = 6) were treated with traditional Ovsynch protocol. The animals (n = 6) of group II were treated with Ovsynch plus protocol which consisted of an initial intramuscular injection of eCG (Folligon) @ 250 IU on day 60 postpartum followed 3 days later by GPG (Ovsynch) protocol. In group-III Control, no treatment was given to animals (n = 6). Treated animals were inseminated at a fixed time between 14 and 20 hrs after second GnRH injection, irrespective of estrus detection. Blood samples were collected from each animal on days 50 and 60 postpartum to determine the status of cyclicity in animals based on serum concentrations of progesterone (P4). A third blood sample was collected on the day of prostaglandin treatment to determine the response of first GnRH injection. Four animals each were cyclic, and two were acyclic in both treatment groups. Four animals each responded to first GnRH treatment in both treatment groups. Similarly, two animals each got conceived giving conception rate of 50% (2/4) in each treatment. In the control group, one out of 6 animals got conceived yielding 16.66 % conception rate (1/6) during the study period. It may be thus concluded that Ovsynch and Ovsynch plus protocol may be used during the early postpartum period to improve the reproductive efficiency in postpartum Sahiwal cows.

BACKGROUND: The increased strength of zirconia has resulted in its widespread application in clinical dentistry. Nevertheless, the fracture of veneering porcelains remains one of the key reasons of failure. OBJECTIVE: The objective of this study was to compare and analyze the influence of surface conditioning methods on the core-veneer bond strength of zirconia restorations. METHODS: Thirty specimens of zirconia core with sizes 10 × 5 × 5 mm were layered with porcelain of sizes 5 × 3 × 3 mm. On the basis of different surface conditioning methods, four groups were made: Group I: abrasion with airborne alumina particles of 110 μm size, Group II: sandblasting with silica coated alumina particles of 50 μm in size, Group III (modified group): alteration with a coating of zirconia powder prior to sintering, and Group IV (control group): metal core specimens. The shear force of all specimens was tested using a universal testing machine with a 0.5 mm/min crosshead speed. One-way analysis of variance (ANOVA) and Tukey’s post hoc pair wise comparison (p= 0.05) were performed to analyze the shear bond strength. A scanning electron microscope was used to assess the fractured specimens. RESULTS: A statistically significant difference was noted between the groups. The mean value of shear bond strength was 40.25 MPa for Group I, 41.93 MPa for Group II, 48.08 MPa for Group III and 47.01 MPa for Group IV. CONCLUSIONS: The modified zirconia group and control group demonstrated a significantly higher mean bond strength than that of Group I, where airborne particle abrasion was used. The scanning electron microscope showed that cohesive fracture in the porcelain veneers was the main problem of failure in altered zirconia. The modified zirconia specimens in Group III demonstrated significantly improved values of shear bond strength.

Intraperitoneal injection of ferric nitrilotriacetate (Fe-NTA) to rats and mice results in iron-induced free radical injury and cancer in kidneys. This study was designed to investigate the effect of catechin, a bioflavonoid with antioxidant potential, on Fe-NTA-induced nephrotoxicity in rats. Four groups were employed in the present study. Group I served as control group, Group II animals received Fe-NTA (8 mg iron/kg body weight i.p.), Group III animals were given 40 mg/kg catechin p.o. twice a day for 4 days and on the 5th day Fe-NTA was challenged, and Group IV animals received catechin alone for 4 days. Renal function was assessed by measuring plasma creatinine and blood urea nitrogen. The oxidative stress was measured by renal malondialdehyde levels, reduced glutathione levels and by enzymatic activity of catalase, glutathione reductase and superoxide dismutase. One hour after a single intraperitoneal (i.p.) injection of Fe-NTA (8 mg iron/kg), a marked deterioration of renal architecture, renal function and severe oxidative stress was observed. Pretreatment of animals with catechin markedly attenuated renal dysfunction, reduced elevated thiobarbituric acid reacting substances (TBARS), restored the depleted renal antioxidant enzymes and normalized the renal morphological alterations. These results clearly demonstrate the role of oxidative stress and its relation to renal dysfunction, and suggest a protective effect of catechin on Fe-NTA-induced nephrotoxicity in rats.
