25. Is Forced Swimming Immobility a Good Endpoint for Modeling Negative Symptoms of Schizophrenia? - Study of Sub-Anesthetic Ketamine Repeated Administration Effects
ABSTRACT Immobility time in the forced swimming has been described as analogous to emotional blunting or apathy and has been used for characterizing schizophrenia animal models. Several clinical studies support the use of NMDA receptor antagonists to model schizophrenia in rodents. Some works describe the effects of ketamine on immobility behavior but there

27. The preventive effects of ascorbic acid supplementation on locomotor and acetylcholinesterase activity in an animal model of schizophrenia induced by ketamine
ABSTRACT Studies have shown that schizophrenic patients seem to have nutritional deficiencies. Ascorbic acid (AA) has an important antioxidant effect and neuromodulatory properties. The aim of this study was to evaluate the effects of AA on locomotor activity and the acetylcholinesterase activity (AChE) in an animal model of schizophrenia (SZ). Rats were sup

28. Propofol attenuates cytokine-mediated upregulation of expression of inducible nitric oxide synthase and apoptosis during regeneration post-partial hepatectomy
Abstract Purpose: To determine the effects of propofol and ketamine anesthesia on liver regeneration in rats after partial hepatectomy (PHT). Methods: Male Wistar albino rats were assigned randomly to four groups of 10. Anesthesia was induced and maintained with propofol in groups 1 and 2, and with ketamine in groups 3 and 4. PHT was undertaken in groups 1

29. Moderate sedation helps improve future behavior in pediatric dental patients – a prospective study
Abstract There is little evidence on the long-term effects of pharmacological management in children undergoing dental treatment. This study aimed to assess children’s behavior in consecutive dental sessions following oral rehabilitation using different pharmacological regimens for behavioral control. Participants were preschoolers who were previously trea

30. Effect of different anesthetic agents on left ventricular systolic function assessed by echocardiography in hamsters
Determination of left ventricular ejection fraction (LVEF) using in vivo imaging is the cardiac functional parameter most frequently employed in preclinical research. However, there is considerable conflict regarding the effects of anesthetic agents on LVEF. This study aimed at assessing the effects of various anesthetic agents on LVEF in hamsters using tran

31. Expression of Ghrelin and GHSR-1a in Long Term Diabetic Rat's Kidney
The aim of this work was to study the relative ghrelin and growth hormone secretagogue receptor (GHS-R)1a gene expression in the kidney of long-term diabetic rats. Forty male Wistar albino rats were divided into four groups: C- control group, DI- one month diabetic rats group, DII- two months diabetic rats group, and DIII- three months diabetic rats group. D

32. Comparison of the effects of magnesium and ketamine on postoperative pain and morphine consumption. A double-blind randomized controlled clinical study
PURPOSE: To compare the effects of magnesium sulfate and ketamine on postoperative pain and total morphine consumption in a placebo-controlled design. METHODS: One hundred and twenty women scheduled for total abdominal hysterectomy were included in this prospective, randomized, double-blind study. Postoperatively, when the Numeric Pain Rating Scale (NPRS)

33. Evaluation of hemosponge in promoting dental socket healing after 3rd mandibular premolar extraction in a feline model
Abstract Aim: To investigate the healing process following use of collagen sponges in the dental socket after extraction. Wound complications during the study were also evaluated. Methods: 32 cats were included in this study. IV administration of the combination of diazepam (0.22 mg/kg) and ketamine (10 mg/kg) was used to induce general anesthesia. Surgi

34. Bispectral index in calves anesthetized with xylazine, midazolam, ketamine, isoflurane and subjected to continuous rate infusion of lidocaine
PURPOSE:To assess the bispectral index (BIS) and recovery in calves anesthetized with xylazine, midazolam, ketamine and isoflurane and subjected to CRI of lidocaine.METHODS:Xilazine was administered followed by ketamine and midazolam, orotracheal intubation and maintenance on isoflurane using mechanical ventilation. Lidocaine (2 mg kg-1 bolus) or saline (0.9

35. The investigation of airway management capacity of v-gel and cobra-PLA in anaesthetised rabbits
PURPOSE:To evaluate the applicability and airway management capacity of v-gel(r) and Cobra PLA in rabbit anaesthesia during assisted (AV) or controlled ventilation (CV).METHODS:This study was carried out in 44 adult New Zealand white rabbit. Baseline arterial pH, PaCO2 and PaO2 values were recorded. Anaesthesia was induced with 5 mg/kg xylasine and 35 mg/kg

36. Preemptive analgesia effects of Ketamine in patients undergoing surgery. A meta-analysis
PURPOSE: To evaluate the preemptive analgesia effects of ketamine for postoperative pain. METHODS: PubMed, EMBASE and Cochrane Library were searched to identify randomized controlled trials (RCTs) involved in ketamine for preemptive analgesic up to March 2013. The relative risk (RR) or mean difference (MD) as well as the confounding 95% confidence interval
