Background: Diabetes mellitus is a chronic metabolic disorder that develops due to insulin deficiency or insulin resistance. Recent animal and human studies have reported bromocriptine to be effective in the management of type 2 diabetes mellitus. The present study was done to evaluate the antihyperglycemic effect of bromocriptine in dexamethasone induced hyperglycemic rats.Methods: Male wistar rats were used and divided into 5 groups. Dexamethosone was used to induce hyperglycemia in group B-E. Group A was the untreated control group, group B was the standard control group, group C was the oral 10 mg/kg of bromocriptine dissolved in 0.9% normal saline, group D was the oral 20 mg/kg metformin dissolved in 0.9% normal saline, group E was the oral 10 mg/kg bromocriptine+20 mg/kg metformin dissolved in 0.9% normal saline. Fasting blood glucose, post prandial blood glucose and body weight was estimated on day 1, 15, 30.Results: It was seen that dexamethasone induced hyperglycemia and increase in body weight in male wistar rats, which were significantly controlled by oral bromocriptine and bromocriptine with metformin combination.Conclusions: Results obtained from this study showed that bromocriptine can be a promising drug with novel mechanism to treat type 2 diabetes mellitus.

A successful treatment of dental implant needs a good jaw bone support, which depends on healthy bone metabolism. Bone metabolism can be affected by Diabetes Mellitus (DM). It may trigger various complications, including osteoporosis. Molecular triads consisting of Receptor Activator of NF-kappaB (RANK), Activator of nF-κB Ligand (RANKL), and osteoprotegerin (OPG), have an important role in the formation, function, and osteoclast survival. In this study, molecular triads were observed on mandible and femur bones in type 2 DM Wistar rats. The aim of this study was to observe the molecular triad RANK / RANKL / OPG expressions in type 2 DM Wistar rats. This laboratory research used 18 male Wistar rats divided into three groups: nondiabetic group (control), uncontrolled DM injected with single dose of Streptozotocin (STZ), and controlled DM treated with Metformin. On day 20, the mandible and femur were collected and specimen processing was carried out. The results of RANK / RANKL / OPG expressions were obtained from immunohistochemical staining. In both mandible and femur groups, RANK, RANKL, OPG expressions showed no difference between the control and uncontrolled DM groups. RANKL / OPG ratio in uncontrolled DM was higher than that in the control group. RANK expression was lower in uncontrolled DM group compared with controlled DM, and the RANKL expression in uncontrolled DM group was higher than that in the controlled DM group. RANKL / OPG ratio was lower in the controlled DM group. The study suggested that DM affects resorptive activity in mandible and femur bones which can be observed via RANK/RANKL/OPG.

Objective: To study the effectiveness of prophylactic ephedrine to prevent hypotension caused by induction of anesthesia with propofol and sufentanil in elderly hypertensive patients. Methodology: 70 elderly ASA grade II-III hypertensive patients undergoing elective general anesthesia were randomized into two groups to receive either intravenous ephedrine,100 ug/kg in 5ml normal saline (Group B), or an equal volume of normal saline (Group A) before induction. Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) and Heart Rate (HR) were recorded at T0 (after entry to the operating room), T1 (1 min after induction), T2 (2 min after induction), T3 ( 3 min after induction), T4 (4 min after induction), T5 (when intubated), T6 (2 min after intubation), and T7 (at the start of the procedure), as well as the incidence of hypotension and bradycardia. Results: SBP, DBP and HR were not significantly different at T0 and were significantly different at T1 to T7 after anesthesia induction. There were statistically significant effect on hypotension and bradycardia between the two groups and group B have a lower risk of hypotension and bradycardia relative to group A. SBP and DBP decreased significantly after induction in both groups. HR decreased significantly in group A while increased in group B. Conclusion: Ephedrine pretreatment can minimize hypotension and bradycardia caused by propofol and sufentanil during the induction of general anesthesia in elderly patients with hypertension.

Background Caudal epidural analgesia with bupivacaine is very popular in paediatric anaesthesia for providing intra- and postoperative analgesia. Several adjuvants have been used to prolong the action of bupivacaine. Objectives To compare the efficacy of ketamine, fentanyl and clonidine in terms of quality and duration of analgesia they produce when added with caudal bupivacaine by single shot technique in children. Methods Eighty children, age one to ten years, undergoing sub-umbilical surgery, were prospectively randomized to one of four groups: caudal analgesia with 0.75 ml/kg of 0.25% bupivacaine in normal saline (Group B) or caudal analgesia with 0.75 ml/kg of 0.25% bupivacaine with 1 μg/kg of clonidine in normal saline (Group BC) or caudal analgesia with 0.75ml/kg of 0.25% bupivacaine with ketamine 0.5mg/kg (Group BK) or caudal analgesia with 0.75ml/kg of 0.25% bupivacaine with fentanyl 1mcg/kg (Group BF). Post-operative pain was assessed for 24 hours using the FLACC scale. Results The mean duration of analgesia was significantly longer in Group BC (629.06 ± 286.32 min) than other three groups P < 0.05. The pain score assessed using FLACC scale was compared between the four groups, and children in Group BC had lower pain scores, which was statistically significant. The requirement of rescue medicine was lesser in Group BC. Clonidine in a dose of 1 μg/kg added to 0.25% bupivacaine for caudal analgesia, during sub-umbilical surgeries, prolongs the duration of analgesia of bupivacaine, without any side effects in compare to fentanyl or ketamine. Conclusion We conclude that clonidine in a dose of 1 μg/kg, added to 0.25% bupivacaine for caudal analgesia and administered as a 0.75 ml/kg mixture in children, for sub-umbilical surgery, significantly prolongs the duration of post-operative analgesia when compared to 0.75 ml/kg of 0.25% bupivacaine in normal saline than 0.75 ml/kg of 0.25% bupivacaine with ketamine 0.5 mg/kg or 0.75 ml/kg of 0.25% bupivacaine with fentanyl 1 mcg/kg or 0.75 ml/kg of 0.25% bupivacaine alone, without any side effects.

Introduction: Laparoscopic cholecystectomy has been the gold standard in the treatment of gallstones since last decades. Beside several benefits of laparoscopic cholecystectomy compared with open surgery, postoperative pain is still a frequent melancholy.  Hence, pain management is utmost regarding patients' comfort. The main objective of the study was to compare the effect of intraperitoneal hydrocortisone plus bupivacaine with bupivacaine alone on pain relief following laparoscopic cholecystectomy.   Methods: A randomized study was conducted from December 2015 to August 2015 that included 100 patients aged 20 to 60 years of both genders who were found to have symptomatic gallstones and were scheduled for elective laparoscopic cholecystectomy at Lumbini Medical College. Patients randomly received 100 mg hydrocortisone plus 100 mg bupivacaine in 200 ml normal saline (group A) or 100 mg bupivacaine in 200 ml normal saline (group B) into the peritoneum. Post-operative abdominal and shoulder pain were evaluated using Visual Analog Score (VAS). The patients were also followed up for postoperative analgesic requirements, and recovery variables. Data were collected, tabulated and analyzed statistically using SPSS version 19.   Results: Total number of patients in this study were 100. Age and gender among both groups were comparable. VAS scores for pain was significantly lower for group A as compared to group B at 0, 2, 4, 6, 12, and 24 hours. Time of oral intake in hrs for liquids and solids was statistically significant in Group A compared to Group B. Rescue analgesic requirement was also significantly low in Group A compared to Group B. Hospital stay in both group were comparable.   Conclusion: Combination of hydrocortisone plus bupivacaine can relieve pain after laparoscopic cholecystectomy better compared to bupivacaine alone when administered intraperitoneally.

Background: Thermoregulatory system coordinates defenses against environmental temperature to maintain internal core temperature within a narrow range, thus optimizing normal body function and homeostasis in humans. Anaesthetic induced thermoregulatory impairment and hence hypothermia in cold environments. Shivering is an important complication of hypothermia. Shivering is an involuntary, oscillatory muscular activity that augments metabolic heat production upto 600% above basal level to increase temperature. It is associated with substantial adrenergic activation, discomfort and can double or even triple oxygen consumption and carbon dioxide production. Potent anti-shivering properties have been attributed to numerous drugs including biogenic monoamines, cholinomimetics, cations, endogenous peptides and possibly N-methyl-D- aspartate (NMDA) receptor antagonists like ketamine, tramadol and clonidine. Aim: To evaluate the effectiveness of prophylactic use of intravenous ketamine, clonidine and tramadol in control of shivering and to note any side-effects of the drugs used. Methods: A total number of 120 ASA I and 2 patients of either sex belonging to age group 18-60 years posted for Lower Abdomen and Lower Limb surgeries under subarachnoid block were divided into four groups of 30 each. Group P (control group): Patients received 10mL of normal saline IV as placebo. Group K: Patients received Inj. Ketamine 0.5mg/kg BW IV diluted to 10ml in Normal Saline. Group C: Patients received Inj. Clonidine 75mcg IV diluted to 10ml in Normal Saline. Group T: patients received Inj. Tramadol 0.5mg/kg BW IV diluted to 10ml in normal saline. Results: We conclude that giving Ketamine 0.5mg/kg,Clonidine 75mcg or tramadol 0.5mg/kg i.v. prophylactically just before subarachnoid block significantly decreased the incidence of shivering without causing any major side effects. Conclusion: Ketamine, Tramadol or Clonidine decrease shivering during spinal anesthesia.

PURPOSE: To evaluate the metabolic changes induced by pre-administration of L-alanyl-glutamine (L-Ala-Gln) and omega-3 (ω-3) in rats subjected to sepsis. METHODS: Eighteen male Wistar rats were randomized into three groups (n=6) and treated with saline (group Control-G-1), L-Ala-Gln (0.75 mg /kg , G-2) or ω-3 (0.2 g /kg, G-3 ) administered intravenously 3, 2 and 1 day and 30 minutes before induction of sepsis. Samples (blood, striated muscle and liver) were collected 48 hours after induction of sepsis, to measure the concentrations of metabolites (pyruvate, lactate, glucose and ketone bodies. RESULTS: There was a significant increase in muscle glycolysis and gluconeogenesis in the liver in rats treated with L-Ala-Gln and ω-3, compared to the control group, 48 hours after induction of sepsis. CONCLUSION: Pre-administration of L-Ala-Gln or ω-3 to rats subjected to sepsis resulted in similar metabolic changes, by rising glycolysis in peripheral tissues and stimulating hepatic gluconeogenesis and ketogenesis, resulting in increased energy supply to septic rats.

: Comparative studies evaluating budesonide and saline nasal irrigations for patients with polyposis/ rhinosinusitis are deficient in the current literature. This study aimed to evaluate the effectiveness of budesonide nasal irrigations compared with saline irrigations during postoperative care of patients with rhinosinusitis.: A total of 100 patients who underwent functional Endoscopic Sinus SurgeryESS) were randomly divided into two groups (A and B) of 50 participants each (normal saline [NS] + budesonide irrigation and NS irrigation alone, respectively). Pre- and post operative evaluation was done with a 22-item sinonasal outcomes test (SNOT-22), and Lund Kennedy endoscopic (LKE scores) in second and sixth week. : The condition of the patients significantly improved in both intervention arms related to SNOT-22 and LKE score at each postoperative visit (Group A: p&#60;0.001, Group B: p&#60;0.001). The reduction of SNOT 22 score was higher in budesonide group by 10% (mean SNOT 22 score from 33.31 to 15.84) compared to normal saline group (mean SNOT 22 score from 37.49 to 22.24). The reduction of LKEscore was higher in budesonide group by 18.69% (mean LKE score from 4.49 to 2.71) compared to normal saline group (mean LKE score from 5.02 to 4). : Steroid nasal irrigation is a good option in postoperative EES patients. The difference of reduction of both SNOT 22 score and LKEscore was statistically significant (p &#60;0.05 and p&#60;0.01 respectively) by repeated contrast test. This study is one of the few comparative studies evaluating budesonide and saline nasal irrigations in post-ESS patients.

The effect of strychnine sulfate upon spontaneous locomotor activity in an open field was determined for 20 naive male Wistar rats. The experimental Ss were injected ip with 1.0 cc/kg of a 01% solution of strychnine sulfate in normal saline and the control Ss received a similar injection of 1.0 cc/kg of normal saline. All Ss were given 2 trials 7 days apart in the open field, with the injections preceding the second trial. The behavioral change from Trial 1 to Trial 2 for the control group was compared with that for the experimental group. Strychnine sulfate significantly reduced spontaneous locomotor activity in rats. A significant correlation was found between scores on the first and second trials of the experimental Ss. It was suggested that the concept of “orienting-exploratory behavior” could account for reduced locomotor activity.
