DEVELOPMENT AND VALIDATION OF A SIMPLE UV SPECTROPHOTOMETRIC METHOD FOR THE ESTIMATION OF SALBUTAMOL SULPHATE FROM PHARMACEUTICAL FORMULATIONS
Objective: The present study was undertaken to develop a rapid, simple, specific and economic ultraviolet (UV) spectrophotometric method for estimating the Salbutamol Sulphate (SS) in pharmaceutical formulations.
Methods: The analysis was performed at λ max 276 nm using Sorenson’s isotonic phosphate buffer pH 7 (SIPB pH 7) as blank/diluent. The method was validated by following the analytical performance parameters as suggested by International Conference on Harmonization (ICH) which included accuracy, precision, linearity.
Results: The drug follows the beer’s lambert’s law in the concentration range of 12.5-37.5μg/ml and exhibited good correlation coefficient (0.9997) and excellent mean recovery. Percentage RSD for precision and accuracy of the method was found to be less than 2%. This method was successfully applied for the determination of the Salbutamol Sulphate in commercial brands of Indian market and the results were in good agreement with the label claims. The developed method was suitable and specific to the analysis of Salbutamol Sulphate even in the presence of common excipients.
Conclusion: The obtained results proved that the validated method can be employed for the routine analysis of Salbutamol Sulphate in bulk as well as in the commercial formulations
Perception and attitudes of medical students toward communication, chronic disease and death
Background: Medical students of today’s world found difficulty in communication when they faced with dying patients, how they would feel, what are their perception about caring of patients with chronic disease. These are often unspoken and neglected issues.Methods: It was a cross-sectional comparative questionnaire based survey of the 2nd year medical students and interns. Students were evaluated using a questionnaire consisting of 15 Likert type statements.Results: Completed questionnaire received from 89 out of 100 students. All students strongly agreed upon the commutation with patients. Interns (37.03%) were strongly disagreed (p=0.001) on not curing the patient is a failure of doctors. Interns (32.58%) were significantly more likely to be less worried (p<0.01) about death of the patient and to indicate cancer is a non-curable disease (p<0.001) when compared to 2nd MBBS. Students from both the groups distressed, while communicating with dying patients and relatives of dying patients.Conclusion: Perception of students regarding caring of chronically ill-patients and death related issues needs improvement. We believe that integrating different teaching strategies and training programs regarding this issue should begin at early stages of undergraduate medical curriculum
An Odontologist’s Key to Sex Determination: Study Analysis of Mandibular Canine Teeth in South Indian Population
Sex determination of a person becomes the first priority of a forensic investigator in the process of identification. Dental evidence pours in an invaluable informative data towardachieving the final positive results in establishing the unknown’s identity. Studies have shown that the mandibular canine resist disease, survive extreme postmortem environmental conditions and presents the highest sexual dimorphism amongst all teeth, making them an ideal teeth in forensic identification procedures. The aim of present study was to know the use of the mandibular Canine teeth’s morphological measurements in assessing sex in South Karnataka population. In the sample size of 80 males and females (40 males and 40 females) in the age-group 18 to 22 years, mandibular canine width and intercanine distance measurements were noted intraorally. The MCI and sexual dimorphism was calculated
Intrathecal morphine in combination with bupivacaine as pre-emptive analgesia in posterior lumbar fusion surgery: a retrospective cohort study
Abstract Background The purpose of this study was to evaluate the efficacy of intrathecal morphine (ITM) in combination with bupivacaine as pre-emptive analgesia in patients undergoing posterior lumbar fusion surgery. This is in comparison with traditional opioid analgesics such as intravenous (IV) morphine. Methods Two groups were identified retrospectively. The first (ITM group) included patients who had general anaesthesia (GA) with low-dose spinal anaesthesia prior to induction using 1–4 mls of 0.25% bupivacaine and 0.2 mg ITM. 1 ml of 0.25% bupivacaine was administered per hour of predicted surgery time, up to a maximum of 4 ml. The insertion level for the spinal anaesthetic corresponded to the spinal level of the iliac crest line and the level at which the spinal cord terminated. The control group had GA without any spinal anaesthesia. Patients were instead administered opioid analgesia in the form of IV morphine or diamorphine. The primary outcome was the consumption of opioids administered intraoperatively and in recovery, and over the first 48 h following discharge from the post-anaesthesia care unit (PACU). Total opioid dose was measured, and a morphine equivalent dose was calculated. Secondary outcomes included visual analogue scale (VAS) pain scores in recovery and at day two postoperatively, and the length of stay in hospital. Results For the ITM group, the median total amount of IV morphine equivalent administered intraoperatively and in recovery, was 0 mg versus 17 mg. The median total amount morphine equivalent, administered over the first 48 h following discharge from PACU was 20 mg versus 80 mg. Both are in comparison with the control group. The median length of stay was over 1 day less and the median VAS for pain in recovery was 6 points lower. No evidence was found for a difference in the worst VAS for pain at day two postoperatively. Conclusion ITM in combination with bupivacaine results in a significantly decreased use of perioperative opioids. In addition, length of hospital stay is reduced and so too is patient perceived pain intensity. Trial registration The study was approved by the ethics committee at The Robert Jones and Agnes Hunt Orthopaedic Hospital as a service improvement project (Approval no. 1617_004). </jats:sec
Physicochemical and textural quality attributes of gluten-free bread formulated with guar gum
The objective of this study was to assess the combined effect of guar gum (GG) and water content (WC) on the rheological properties of batter, and the physicochemical and textural properties of bread. Batches of gluten-free bread used a base formulation of rice (50%), maize (30%) and quinoa flour (20%), with different levels of GG (2.5, 3.0 or 3.5%) and water (90, 100 or 110%) in a full factorial design. Higher GG doses (p<0.001) tended to produce batters of lower stickiness, work of adhesion and cohesive strength; yet, of higher firmness, consistency, cohesiveness and viscosity index. These batters yielded loaves of lower (p<0.001) specific volume and baking loss; and crumbs of lower (p<0.001) aw, pH, mean cell area, void fraction, mean cell aspect ratio; and higher (p<0.001) hardness, adhesiveness, springiness, cohesiveness, chewiness, resilience, mean cell density, cell size uniformity and mean cell compactness. The sticker and less consistent batters produced with higher WC rendered larger bread loaves of softer and more cohesive and springy/resilient crumbs with greater mean cell size and void fraction. Gluten-free loaves of good appearance in terms of higher specific volume, lower crumb hardness, higher crumb springiness, and open grain visual texture were obtained in formulations with 110% WC and GG doses between 2.5 and 3.0%.Eng.
