Allium cepa L (A.cepa; onion) is a traditional nutraceutical and medicinal plant that contains phenolics and flavonoids that have potential anti-inflammatory, anti-cholesterol, anticancer, and antioxidant properties. Quercetin is a plant-derived flavonoid found in fruits, vegetables, leaves and grains. It also has antioxidant, anti-inflammatory and antidepressant effects. The present study is aimed to investigate the anti-stress and nootropic effects of A.cepa bulb and quercetin in mice. Animals were divided into control and 2 test groups. Control mice were received drinking water while test groups were treated with suspension of grinded onion bulb in water (200 mg/kg; test group 1) and intraperitoneal injection of quercetin dissolved in ethanol (20mg/kg/ ml; test group 2) daily for 14 days. Behavioral activities of animals were monitored 14 days post administration of A.cepa and quercetin. Antidepressant effects were measured by forced swimming test (FST). Anxiolytic effects were monitored by using light dark activity (LDA) test and elevated plus maze (EPM) test and memory functions were assessed by morris water maze (MWM) test. Results showed that both A.cepa bulb and quercetin increased time spent in light box and open arm of LDA and EPM, exhibited anxiolytic effect than control group. A significant increase in immobility time was observed in FST in test groups than control suggesting antidepressant like effects. Moreover, nootropic effect were assessed by MWM showed significant increased in latency escape while observing short and long term memory for both test groups than control. It is suggested that both A.cepa and quercetin have anti-stress and nootropic effects.

Background: Anxiety disorders are the most prevalent class of psychiatric condition. Medications commonly given for treatment can elicit several central nervous system (CNS) side-effects that patients find difficult to tolerate. So there is a need for new pharmacotherapeutic approaches to treat anxiety with greater efficacy and fewer side effects. Hence this study has been taken up to evaluate the anxiolytic effect of furosemide at three different doses (75mg/kg, 150mg/kg and 200mg/kg) in Albino rats.Methods: After obtaining approval from the institutional animal ethical committee 30 Albino rats weighing about 150-200gm were taken and divided into 5 groups of 6 rats each. Group 1: Normal Saline 10ml/kg (control); Group 2: Diazepam 2mg/kg (standard); Group 3: Furosemide 150mg/kg (test group 1); Group 4: Furosemide 200mg/kg (test group 2); Group 5: Furosemide 75mg/kg + Diazepam 1mg/kg (sub threshold dose). The anxiolytic activity of furosemide was tested by elevated plus maze and digital actophotometer models. Data was analysed using one way ANOVA followed by Posthoc Tukey’s test.Results: Furosemide (150mg/kg and 200mg/kg) have shown significant increase in open arm entries (p<0.05) and time spent in open arm (p<0.05) compared to control. Also furosemide (150mg/kg and 200mg/kg) have shown statistically significant decrease in locomotor activity (p<0.05) compared to control in actophotometer model. Potentiation of time spent and number of entries in open arm and decrease in locomotor activity were noticed when sub threshold doses of combination of diazepam and furosemide were used.Conclusions: These results suggest that furosemide possesses significant anxiolytic activity at both the doses. Furosemide given in sub threshold dose potentiates the antianxiety effect of sub threshold dose of diazepam when used in combination. Hence, after further studies, furosemide can be used as an anxiolytic drug.

Introduction: Removable dentures are used by 20% of the population. These may be accompanied by denture stomatitis in 15-70% of patients. The choice of the optimal cleansing agent for removable dental prostheses is of high significance. Aim: The aim of our research was to study the influence of removable denture cleansing products on the adhesion of microorganisms and yeast. Materials and Methods: We manufactured 144 specimens of standardized round shape with a diameter of 10 mm from 4 types of modern polymeric materials used by prosthetic dentistry to produce removable dentures, 12 specimens of each material were placed into suspensions of bacterial cultures of Staphylococcus aureus, Escherichia coli, Candida albicans, then into “ClearaSept” (Test group 1), “Рrotefix active cleanser” (Test group 2), saline solution (Control group), followed by nutrient media. The adhesion index was calculated and analyzed. Results: There was no reliable lowering of adhesion index of Staphylococcus Aureus to all materials detected in Test group 1 (U=6, p>0.05 for Bio XS; U=8, p>0.05 for Dental D, Denotokeep Peek, Vertex Rapid Simplified). In Test group 2, the adhesion index of Staphylococcus Aureus reliably decreased to all materials compared to the Control group (U=0, p≤0.01). The adhesion index of Candida albicans and Escherichia coli to all materials in Test group 1 had a minor to moderate reliable reduction compared to the Control group (U=0, p≤0.01). Test group 2 showed a significant reliable decrease in Candida albicans and Escherichia coli adhesion index to all materials in comparison with the Control group (U=0, p≤0.01). Conclusion: The research showed an unreliable or minor and moderate reliable decrease in microorganisms adhesion index depending on the microorganism species after treatment of denture material specimens by antibacterial soap “ClearaSept” and a reliable significant decrease in microbial and yeast adhesion after application of Protefix active cleaner solution, which demonstrates a more significant antimicrobial effect in comparison to “ClearaSept” against Staphylococcus aureus, Escherichia coli, and Candida albicans.

Abstract Objectives Several cultivars of Allium cepa L. have been studied for anti-inflammatory and analgesic activities but there is inadequate information on such biological activities of the concentrated extracts of the Nigerian grown red cultivar A. cepa bulb. Methods The anti-inflammatory models used in this study were Carrageenan-induced paw oedema and formalin-induced paw lick in rats, while acetic acid-induced abdominal writhing, hot plate reaction, hot water tail flick tests in mice were the analgesic models. Results At 30 min post-induction (pi), the inhibition of paw oedema (62.50%) by 200 mg/kg of methanol extract of red cultivar A. cepa bulb (MERCACB) was significantly (p<0.001) higher than that of indomethacin (15.63%) at 10 mg/kg. The paw oedema inhibition at 60 min pi by MERCACB (76.92%) was significantly higher than that of indomethacin (41.03%). At the early phase of formalin paw-lick test, the pain reaction time (PRT) of rat treated with MERCACB (400 mg/kg) was significantly lower than that of indomethacin and the control groups. The hotplate test revealed that PRT of mice treated with 800 mg/kg of MERCACB were significantly (p<0.01) longer in comparism to indomethacin and control groups. The PRT of mice subjected to thermal pain due to hot water and treated with 800 mg/kg of MERCACB was significantly (p<0.05) longer than that of the control group. Conclusions These findings indicate that MERCACB possesses potent anti-inflammatory and analgesic properties which confirm the traditional use of the plant for the treatment of inflammatory diseases and may be useful as a future therapeutic agent.

Abstract Background Endotracheal intubation is known to pose significant physiological, pharmacokinetic, and dynamic changes and postoperative respiratory complications in patients under general anesthesia. Method An RCT trial was organized by the Third Affiliated Hospital at Sun Yat-sen University, China. Patients were eligible for inclusion in the trial if they were over 60 years old and had upper-abdominal surgery during the induction of anesthesia and had enrolled in endotracheal intubations. The primary end point included cardiovascular reactions during the induction of anesthesia and endotracheal intubations and cough events during the recovery period. In the test group, 2 g of lidocaine/prilocaine cream (and in the control group, 2 g of Vaseline) were laid over the surface of the tracheal tube cuff. Results The systolic blood pressure (F value = 62.271, p < 0.001), diastolic blood pressure (F value = 150.875, p < 0.001), and heart rate (F value = 75.627, p < 0.001) of the test group were significantly lower than the control group. Cough events during the recovery period in the test group were better (spontaneous cough, χ2 value = 10.591, p < 0.001; induced cough, χ2 value =10.806, p < 0.001). Conclusion In older patients, coughing and cardiovascular reactions under anesthesia and endotracheal intubations were reduced, as a result of using lidocaine/prilocaine cream on the surface of the tracheal tube cuff.

Abstract Background Seaweeds are a famous traditional food resource in some countries containing different types of secondary metabolites. These marine organisms have shown different biological activities. The aim of this study was to investigate the effects of hexane and methanol extracts of Sargassum plagyophylum on depression. Methods Sargassum plagyophylum was collected from Persian Gulf. The plant was extracted by maceration with methanol-ethyl acetate solvent. The extract was evaporated and partitioned by hexane and methanol solvents. The two partitions were administered i.p. to male mice either a single dose or for 7 days. Depression was evaluated by the forced swimming test (FST) which higher immobility time indicates depressive-like behavior. Results The immobility time during FST decreased significantly by all the doses of the hexane partitions (notably 40 mg/kg; 10 s ± 2 vs. 114 s ± 12 control group). However, only the lowest dose (20 mg/kg) of the methanol partition reduced immobility time during FST (23 s ± 8, p<0.001). Following the long term administration both of the partitions reduced the immobility time in FST (hexane 27 s ± 11, methanol 70 s ± 14, p<0.05 vs. control 140 s ± 14). Conclusion The hexane partition showed antidepressant effects not only by long-term administration but also by the single dose during FST. The 7 days therapy with methanol partition also induced antidepressant behavior, but only the lowest single dose reduced immobility in FST. The methanol partitions possibly have certain substance that interfered with behavior in the FST. Therefore, S. plagyophylum should be considered for further antidepressant studies.

Background Encapsulating peritoneal sclerosis (EPS) is an infrequent but extremely serious complication of long-term peritoneal dialysis. Fibrosis of the submesothelial compact zone and neoangiogenesis underlie the pathophysiology of EPS. Colchicine is a well-known anti-inflammatory and antifibrotic agent that has been used for some fibrosing clinical states, such as liver fibrosis. Objective To determine the antifibrotic and anti-inflammatory effects of colchicine in an EPS rat model in both progression (P) and regression (R). Methods 48 nonuremic albino Wistar rats were divided into 5 groups: control group, 2 mL isotonic saline intraperitoneally (IP) daily for 3 weeks; CG group, IP injection of 2 mL/200 g chlorhexidine gluconate (CG) (0.1%) and ethanol (15%) dissolved in saline, daily for 3 weeks; resting group, CG (0 – 3 weeks) + peritoneal resting (4 – 6 weeks); C-R group, CG (0 – 3 weeks) + 1 mg/L colchicine (4 – 6 weeks); C-P group, CG (0 – 3 weeks) + 1 mg/L colchicine in drinking water (0 – 3 weeks). At the end, a 1-hour peritoneal equilibration test was performed with 25 mL 3.86% peritoneal dialysis solution. Dialysate-to-plasma ratio of urea (D/P urea), dialysate WBC count, ultrafiltration volume, and morphological changes of parietal peritoneum were examined. Result Exposure to CG for 3 weeks resulted in alterations in peritoneal transport (increased D/P urea, decreased ultrafiltration volume; p < 0.05) and morphology (increased inflammation, neovascularization, fibrosis, and peritoneal thickness; p < 0.05). Resting had some beneficial effects on peritoneal derangements; however, once the peritoneum had been stimulated, resting alone was not enough to reverse these pathological changes. Colchicine had more pronounced effects on membrane integrity via decreased inflammation, cell infiltration, and vascularity compared to the resting group. Conclusion We suggest that colchicine may have therapeutic value in the management of EPS.

BackgroundGabapentin, a third-generation antiepileptic drug, is a structural analogue of γ-aminobutyric acid, which is an important mediator of central nervous system. There is clinical data indicating its effectiveness in the treatment of psychiatric illnesses such as bipolar disorder and anxiety disorders.ObjectivesWe aimed to investigate the antidepressant and anxiolytic-like effects and mechanisms of gabapentin in rats.Material and MethodsFemale Spraque–Dawley rats weighing 250±20 g were used. A total of 13 groups were formed, each containing 8 rats: gabapentin (5, 10, 20, 40 mg/kg), amitriptyline (10 mg/kg), sertraline (5 mg/kg), diazepam (5 mg/kg), ketamine (10 mg/kg), gabapentin 20 mg/kg was also combined with amitriptyline (10 mg/kg), sertraline (5 mg/kg), diazepam (5 mg/kg) and ketamine (10 mg/kg). All the drugs were used intraperitoneally as single dose. Saline was administered to the control group. Elevated plus maze and forced swimming tests were used as experimental models of anxiety and depression, respectively.ResultsIt was observed that gabapentin showed an anxiolytic-like and antidepressant-like effect in all doses in rats. Its antidepressant effect was found to be the same as the antidepressant effects of amitriptyline and sertraline. There was no change in the antidepressant effect when gabapentin was combined with amitriptyline and ketamine, but there was an increase when combined with sertraline and diazepam. Gabapentin and amitriptyline showed similar anxiolytic effect, whereas ketamine and diazepam had more potent anxiolytic effect compared with them.ConclusionsThese data suggest that gabapentin may possess antidepressant- and anxiolytic-like effects.

Abstract Background The early postoperative period can be distressing for the patients undergoing rhinoplasty since edema and ecchymosis are common complications. Objectives To analyze the effects of the vibration and pressure treatments in the early postoperative period of rhinoplasty. Methods Sixty patients, who had undergone rhinoplasty, were randomized into 3 groups: group 1 (control group, n = 20) received classic nasal casting, group 2 (n = 20) received nasal cast with an elastic bandage to hold it on the face, and group 3 (n = 20) received vibration treatment in addition to that in group 2 following the rhinoplasty. They were evaluated preoperatively and postoperatively at 3 and 7 days in a prospective study. The postoperative edema and ecchymosis were scored by 2 independent surgeons. The postoperative pain was measured using the visual analog scale, and the necessity of anti-inflammatory medication (and the dose needed) and the cast comfort was questioned. The sebaceous activity of the nose skin was examined. A preoperative and postoperative seventh day sonographic study was performed to evaluate the tissue edema objectively. Results The pressure treatment decreased the edema and ecchymosis significantly compared with the control group. The vibration treatment minimized edema, ecchymosis, sebaceous activity of the nose skin, pain score, and the need for anti-inflammatory medication, and increased the cast comfort significantly compared with the other groups (P &lt; 0.0001). Conclusions Rapid regression of edema and ecchymosis may be achieved using the vibrating nasal cast technique that may minimize patient discomfort, pain, and sebaceous activity following rhinoplasty.

This study investigated, both histologically and histometrically, the efficacy of enamel matrix derived proteins (EMD) associated with bioactive glass (BG) and an absorbable membrane in the treatment of class III furcation defects in mongrel dogs. After surgical defect creation and chronification, the lesions were randomly divided into three groups according to the treatment employed: Test Group 1 - EMD + BG + membrane, Test Group 2 - EMD + membrane and Control Group - BG + membrane. After a 90-day healing period, the dogs were sacrificed. The descriptive analysis and the histometric data showed similar results for the experimental groups in all studied parameters (MANOVA, p > 0.05). The association of Emdogain® with bioglass and GTR, or with GTR only, showed similar results when compared with the ones obtained with bioglass associated with membrane in the treatment of class III furcation defects in dogs. The three modalities of treatment showed partial filling of the furcations, with bone and cementum regeneration limited to the apical portion of the defects.

Studies suggested antioxidant properties of the content of Syzygium aromaticum (clove). The study was conducted to obtain better understanding about the effect of clove on concentration of oxidative stress marker malondialdehyde (MDA) in liver and blood plasma of rat initially induced by carbon tetrachloride (CCl4); and whether blood plasma MDA level might represent liver condition. Experimental research was done using 20 Wistar rats classified into 5 treatment groups: (1) CCl4 - and clove-positive treatment after 3 days of clove treatment, (2) one day after, (3) alpha-tocopherol as positive control, (4) CCl4 only as negative control, and (5) normal control. Wills method was used for MDA concentration measurement. Liver MDA concentration were 0.0262 ± 0.0010 for group 1, 0.0214 ± 0.0047 group 2, 0 for group 3, 0.0077 ± 0.0094 group 4, and 0.0039 ± 0.0009 control group in nmol/mg protein (p = 0.001), whereas in the blood plasma it was 29.6032 ± 6.8021 for group 1, 26.1103 ± 3.6920 for group 2, 1.1612 ± 0.3555 for group 3, 1.4585 ± 1.4747 for group 4, and 2.4217 ± 1.2382 control group in nmol/mL (p = 0.001). Contrary to study in the past, no antioxidant properties were observed in treatment with dose 200 mg clove/kg body weight of rat. Such treatment increased MDA concentration and enhanced CCl4-induced damage in a time-dependent fashion. Strong correlation between MDA concentration in the liver and blood plasma (R = 0.97; p = 0.003) suggested blood plasma utilisation to represent hepatic MDA concentration or damage.
