Aim. To evaluate the character of the course and to determine the features of biochemical manifestations in patients with atrial fibrillation and arterial hypertension combined with extracardiac diseases. Methods. To study the features of the course of persisting form of atrial fibrillation (AF) in patients with arterial hypertension (AH) stage 3 combined with extracardiac diseases. 374 patients aged 45 to 65 years were examined. Among them chronic obstructive pulmonary disease (COPD; n = 37), diffuse toxic goiter (DTG; n = 33), hypothyroidism (HT; n = 69), diabetes mellitus (DM; n = 49) and abdominal obesity (AO; n = 64) of mild and moderate degree were detected. 5 groups were formed: group 1 - AH + AF + COPD, group 2 - AH + AF + HT, group 3 - AH + AF + DTG, group 4 - AH + AF + DM, group 5 - AH + AF + AO. The control group included 56 patients with AH and AF without concomitant diseases, and the comparison group included 36 patients with AF without AH and 30 patients with AH without AF. The study evaluated clinical, anthropometric and laboratory parameters, the results of instrumental diagnostic investigation. The level of galectin-3 was determined in the serum by ELISA. The concentration of brain natriuretic peptide (NT-proBNP) was measured with a panel “NT-proBNP - ELISA - Best”. Multiple comparisons of the groups were performed with Kruskal - Wallis test. To compare binary and categorical parameters, exact two-tail Fisher’s test was used. Optimal multivariate regression models were developed directly and reversely. Verification of statistical hypotheses was carried out with critical value of significance p = 0.05 i.e. the difference was considered statistically significant if p < 0.05. All statistical calculations were performed with the use of R-Studio soft. Results. When assessing the lipid profile in the studied groups, significant differences were detected for HDL (high density lipoprotein) the values of which were the highest in the control group; TC (total cholesterol) was significantly lower in group 1 and 2; LDL (low density lipoprotein) and TG (triglycerides) - in group 3. The level of uric acid in the serum in all clinical groups was higher compared to those of the control group but significance was reached only in group 3. The concentration of K+ in the blood was significantly higher in all groups compared to the control group. The study of NT-proBNP and galectin-3 as markers reflecting the processes of remodeling and myocardial fibrosis in patients with atrial fibrillation combined with arterial hypertension, demonstrated that the average level of NT-proBNP in all groups was higher than in the control group but the difference was significant only in group 5. The level of galectin-3 in the serum of patients with arterial hypertension and atrial fibrillation combined with comorbid extracardiac pathology was significantly higher in the groups compared to the control group (except for group 3 where the number of patients was the lowest) and significantly lower in the comparison group of patients with atrial fibrillation without arterial hypertension. Conclusion. The course of arterial hypertension and atrial fibrillation with concomitant extracardiac diseases is characterized by the changes of biochemistry, which manifest as the changes of lipid profile, electrolyte content and factors inducing fibrosis. The obtained data confirm the possible role of galectin-3 as a biological marker of fibrosis and myocardial remodeling in patients with AF and AH and comorbid extracardiac pathology.

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.

Aim.The aim of this study was to evaluate the effect of different restoration techniques on the formation of internal microgaps between materials and dentin in class V restorations.Materials and Methods.Twenty-five extracted human premolars were prepared with standardized class V cavity outlines (3 mm × 2 mm × 2 mm). The cavities were randomly divided into 5 groups of 10 cavities each and restored according to manufacturer’s instructions: Group 1: preheating (55°C) conventional composite (Filtek Z250), Group 2: flowable composite (Filtek Flow), Group 3: Filtek Flow + Filtek Z250 light-cured separately, Group 4: Filtek Flow + Filtek Z250 light-cured simultaneously, and Group 5 (control): Filtek Z250 at room temperature (23°C). The specimens were then thermocycled and cross-sectioned through the center of the restoration. Subsequently, impressions were taken, and epoxy resin replicas were made. The internal adaptation of the materials to the axial wall was analyzed under SEM.Results.The preheated Filtek Z250 (Group 1) showed better internal adaptation than the room temperature groups(P<0.05). The combination of Filtek Flow with Filtek Z250 which was light-cured separately (Group 3) exhibited better internal adaptation than control group(P<0.05).Conclusion.Different restoration techniques exhibit different behavior regarding internal adaptation to dentin after photopolymerization.

Different procedures of treatment of large follicular ovarian cysts in 177 sows using GnRH, hCG and PGF2α are evaluated in this study. Ovarian cysts were diagnosed by transcutaneous ultrasonography, which was a part of routine pregnancy diagnosis. No treatment was performed in the control group (Group 1, <i>n</i> = 29); the method of treatment used in the other groups immediately after the diagnosis was intramuscular administration of lecirelin in doses 50 µg (Group 2, <i>n</i> = 28), 100 µg (Group 3, <i>n</i> = 27) and 200 µg divided into 2 equal doses administered at a 12-hour interval (Group 4, <i>n<i> = 25) and of hCG in doses 1 500 IU (Group 5, <i>n</i> = 23), 3 000 IU (Group 6, <i>n</i> = 21), and 250 µg of cloprostenol (Group 7, <i>n</i> = 24). Insemination rate (IR), conception rate (CR) in inseminated sows, pregnancy rate (PR = recovery rate), treatment-insemination interval (TII) and treatment-pregnancy interval (TPI) within 42 days after the initial examination were evaluated. In addition PR in groups of sows divided according to parity (1–3, 4–6 and ≥ 7) were also evaluated. IR and PR were higher in Group 4 (84.0% and 44.0%) and lower in Group 1 (17.2% and 6.9%) in comparison with the other groups (<i>P</i> < 0.001 and <i>P</i> < 0.05). CR, TII and TPI did not differ between the experimental groups. PR were similar in sows with different parity. The study proved a positive response in sows with large follicular ovarian cysts to the treatment consisting of 2 administrations of 100 µg GnRH at a 12-hour interval.

Effects of the probiotic (PRO) Lactobacillus plantarum and of the combination of PRO and the prebiotic (PRE) inulin enriched with oligofructose (2%), and PRO with Lini oleum virginale (O) on counts of lactobacilli and coliforms and enzymatic activities in faeces of rats were studied. The rats (n = 60) were divided into 5 groups of 12 subjects. The animals were fed on a high fat diet (10%) for 8 weeks of experiment. Colon cancer was induced by the application of 1,2-dimethylhydrazine (DMH) twice a week in a dose of 20 mg/kg s.c. in groups G2-G5. The rats in group 1 (control 1) received a diet without any supplements. The rats in group 2 (control 2) received 1,2 DMH without any supplements. The rats in group 3 received PRO, group 4 PRO and PRE, and group 5 received PRO and O. A significant decrease (P &lt; 0.05) of coliforms was found out after the application of PRO, PRO-O, and PRO-PRE in comparison with control group G2. Significantly higher (P &lt; 0.05) counts of lactobacilli were determined after the application of PRO-O and PRO-PRE. Significantly lower (P &lt; 0.001) activities of &beta;-galactosidase, &beta;-glucuronidase and &alpha;-glucosidase were observed in PRO, PRO-PRE and PRO-O, while in the case of the enzyme &beta;-glucosidase the activity was lower only after the addition of PRO-O. The protective effect of lactobacilli was observed in the order PRO-O, PRO-PRE, and PRO. It was shown that combinations of PRO-O and PRO-PRE had a synergistic effect which was higher than the effect of administering only PRO.

Thermocycling simulates, in vitro, thermal changes that occur in the oral cavity. The aim of this study was to evaluate the influence of the number of cycles on microleakage. Class V cavities (1.5 mm deep, 3 mm in height and 3 mm in width) were prepared in bovine teeth, restored with a Single Bond/Z250 restorative system (3M/ESPE) and then divided into five groups of ten teeth each: group 1 was not thermocycled (control group), and groups 2, 3, 4 and 5 were thermocycled 500, 1,000, 2,500 and 5,000 times, respectively (5º-55º ± 2ºC, 15 s dwell time). The teeth were immersed in 0.5% basic fuchsin aqueous solution for 24 h, sectioned and the sections with the highest degree of microleakage were selected, scanned and the extent of dye penetration was measured by the ImageTool program. The results submitted to one-way ANOVA showed no significant differences between the groups (p > 0.05). The averages of microleakage values in millimeters were: group 1 (3.92); group 2 (3.13); group 3 (4.48); group 4 (4.33) and group 5 (3.42). Thus, it was concluded that there is no relation between the increase of the number of cycles and the increase in microleakage.

OBJECTIVEContralateral peripheral neurotization surgery has been successfully applied to rescue motor function of the hemiplegic upper extremity in patients with central neurological injury (CNI). It may contribute to strengthened neural pathways between the contralesional cortex and paretic limbs. However, the effect of this surgery in the lower extremities remains unknown. In the present study the authors explored the effectiveness and safety of contralateral peripheral neurotization in treating a hemiplegic lower extremity following CNI in adult rats.METHODSControlled cortical impact (CCI) was performed on the hindlimb motor cortex of 36 adult Sprague-Dawley rats to create severe unilateral traumatic brain injury models. These CCI rats were randomly divided into 3 groups. At 1 month post-CCI, the experimental group (Group 1, 12 rats) underwent contralateral L-6 to L-6 transfer, 1 control group (Group 2, 12 rats) underwent bilateral L-6 nerve transection, and another control group (Group 3, 12 rats) underwent an L-6 laminectomy without injuring the L-6 nerves. Bilateral L-6 nerve transection rats without CCI (Group 4, 12 rats) and naïve rats (Group 5, 12 rats) were used as 2 additional control groups. Beam and ladder rung walking tests and CatWalk gait analysis were performed in each rat at baseline and at 0.5, 1, 2, 4, 6, 8, and 10 months to detect the skilled walking functions and gait parameters of both hindlimbs. Histological and electromyography studies were used at the final followup to verify establishment of the traumatic brain injury model and regeneration of the L6-L6 neural pathway.RESULTSIn behavioral tests, comparable motor injury in the paretic hindlimbs was observed after CCI in Groups 1–3. Group 1 started to show significantly lower slip and error rates in the beam and ladder rung walking tests than Groups 2 and 3 at 6 months post-CCI (p < 0.05). In the CatWalk analysis, Group 1 also showed a higher mean intensity and swing speed after 8 months post-CCI and a longer stride length after 6 months post-CCI than Groups 2 and 3 (p < 0.05). Transection of L-6 resulted in transient skilled walking impairment in the intact hindlimbs in Groups 1 and 2 (compared with Group 3) and in the bilateral hindlimbs in Group 4 (compared with Group 5). All recovered to baseline level within 2 months. Histological study of the rat brains verified comparable injured volumes among Groups 1–3 at final examinations, and electromyography and toluidine blue staining indicated successful regeneration of the L6-L6 neural pathways in Group 1.CONCLUSIONSContralateral L-6 neurotization could be a promising and safe surgical approach for improving motor recovery of the hemiplegic hindlimb after unilateral CNI in adult rats. Further investigations are needed before extrapolating the present conclusions to humans.

Chloroquine has gained great emphasis in the treatment of malaria. This study sought experimentally to determine the histomorphological and weight changes in the testes of male mice infected with Plasmodium berghei and treated with chloroquine. The study used 30 Swiss mice divided into five groups. Group 1 is Control that was not infected with Plasmodium berghei and not treated with chloroquine as control, Group 2 is Plasmodium (Plasmodiul berghei) Infected animals but not treated, Group 3 is Plasmodium Infected animals + Chloroquine (5mg/kg), Group 4 is Plasmodium Infected animals + Chloroquine (10mg/kg) and Group 5 is Plasmodium Infected animals + Chloroquine (15mg/kg). The mice were treated for 7 days after parasitaemia was confirmed and the Group 2-5 testes studied with reference to Group 1. The results showed that the Group 2 showed a little distortion, difference in spermatogenic activities and increased cellular activities; Group 3 showed large, convoluted tubules, moderate number of spermatids and large interstitial spaces, Group 4 showed Large seminiferous tubules, large spermatids, increased distortion and group 5 showed shrinking of seminiferous tubules, degeneration of interstitial cells of Leydig cells and Sertolic cells with spermatids. Groups 1-5 showed no significant effect in in body weights and testes weights of Swiss mice. Plasmodium berghei (malaria) and chloroquine have effects on histomorphological structures of Swiss mice testes but not on their teste’s weights. The testicular section from Swiss mice infected with malaria and treated at various doses when compared with the Control (Group 1) showed some moderate distortion in some structures like seminiferous tubules, connective tissues between the tubules, lumen and interstitial spaces. It can be deducted that Plasmodium berghei which caused parasitaemia in mice could cause a little tissue effect on mice if not treated.

Background: Most part of ram spermatozoa membrane has unsaturated fatty acids (phospholipids). Membrane structure of cells is composed of double ordered phospholipid layers adorned with mosaic-like protein, glycoprotein and glycolipids. Sperm freezing protocols could be negatively affected on ram sperm motility, viability and acrosome integrity during cryopreservation. For these reasons, researchers were designed their topics has led to the search for effective antioxidant systems against peroxidative damage and spermatozoon dysfunction. There are three protective enzymatic systems against reactive oxygen species (ROS) damage in sperm. These include superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase / reductase cycles Catalase (CAT) is a hemo-protein in the enzyme tetramer structure. The aim of this study was to investigate the effects of trehalose, catalase and their combinations on ram sperm parameters after the cryopreservation/thawing process.Materials, Methods & Results: At the out of breeding season (March-May) seven rams (1-3 years of age) were used in this study. Ejaculates were collected by electro-ejaculator twice a week. Pooled ejaculates were at 37°C, divided into six aliquots, diluted with the Tris based extender containing Trehalose 25 mM (Group-1), Trehalose 50 mM (Group-2), Catalase 200 µg (Group-3), Catalase 400 µg (Group-4), Trehalose 50 mM + Catalase 400 µg (Group-5) and no anti-oxidant (control), respectively, were cooled to 5°C than frozen in 0.25 mL French straws on the nitrogen vapour and stored in liquid nitrogen. The extender supplemented with Group 1 (54.1 ± 1.53; 73.1 ± 4.37), 50 mM (58.3 ± 4.01; 63.1 ± 0.30) and Group 5 (56.6 ± 1.05; 58.3 ± 0.55) resulted in higher subjective motility in comparison to the control (40.0 ± 3.87; 40.5 ± 0.22) group respectively (P < 0.05). Besides, Group 1 (60.16 ± 4.39) and Group 5 (59.60 ± 2.21) led to higher CASA total motility when compared to control (44.40 ± 8.13) group (P < 0.05). Sperm progressive motility was better in Group 1 (20.57 ± 6.90) than the Group 3 (10.63 ± 3.59) [P < 0.05]. Casa kinetic parameters of catalase 200 (Group 3) was higher values than other groups in VCL, VSL, VAP, LIN parameters (P < 0.05). There were no statistically significant differences on the membrane integrity parameter between the groups (P > 0.05).Discussion: Freezing ram sperm is extremely difficult process when compared bull and dog semen. Previous studies showed that antioxidants which were adding into the ram freezing extender gave positive effects solely or combination. In this study similar results were taken at trehalose 25, 50 mM and trehalose 50 mM + catalase 400 µg except 200 and 400 µg catalase groups. These findings supported some researches but lots of them opposite of catalase results. Catalase is found semen and ameliorates the sperm parameters when adding the liquid storage.  Also after diluted and equilibrated catalase groups motilities were better than the control group. During the freezing stage catalase efficiency has been restricted. On the other hand when it combined with the trehalose 50 mM, catalase activity was triggered. Trehalose acts on sperm as non-permanent had a protective action related both osmotic effect and specific interactions with membrane phospholipids. Our data suggest that solely Trehalose 50 mM or combination with Catalase 400 µg can be added to Tris based extender for improving the post-thawed sperm quality in ram semen.

Hypercholesterolemia and hypertriglyceridemia are considered as important risk factors during the atherosclerotic process. The aim of the present investigation was to study the total cholesterol (TC), low-density lipoprotein cholesterol (LDLC), high density lipoprotein (HDL), triglyceride (TG), platelet levels and hydroxyproline fractions during the pathogenesis of atherosclerosis. For this purpose, twenty five 12-weeks, New Zealand white male rabbits, were purchased, individually caged, and divided into either control group or cholesterol-fed group. The control group (n = 10) was fed 100 g/day of normal diet, ORC-4 (Oriental Yeast Co. Ltd., Tokyo, Japan) for a period of 15 weeks. The cholesterol-fed group (n = 15) was fed a high cholesterol and saturated fat diet of ORC-4 containing 1% cholesterol plus 1% olive oil (100 g/day) for periods of 5 (group 1), 10 (group 2) and 15 (group 3) weeks. Blood sample from each animal was taken at the end of the experimental period for the biochemical analysis. The results of the present study showed that TC, LDLC, TG, HDLC and platelets were significantly (P < 0.01) increased in cholesterol-fed rabbits as compared with control rabbits. The serum hydroxyproline (Hyp) in rabbits belonging to group 1 showed no significant alteration when compared to control group. Group 2 rabbits showed a significant increase of 103% (P < 0.01) and 100% (P < 0.001) in free and protein—bound hydroxyproline fractions respectively when compared to control rabbits. However, there was no significant change in peptide—bound and total serum hydroxyproline levels as compared to the control group (P > 0.05). There was no significant (P > 0.05) decrease of free serum hydroxyproline in group 3 rabbits when compared to control rabbits. On the other hand, group 3 rabbits showed a significant increase in peptide-bound and protein- bound Hyp by 517% (P < 0.05) and 100% (P < 0.01) respectively when compared to control rabbits. However, total serum Hyp in group 3 rabbits showed no significant (P > 0.05) change when compared to control rabbits. These results suggest that feeding rabbits high cholesterol and saturated fat diet for feeding periods of 5, 10 and 15 weeks induced significant change in TC, LDLC, HDL, TG, platelet levels and various Hyp fractions in serum without any significant change in the total Hyp content.
