Abstract
Aim: Existing gaps in nursing curriculum particularly related to medication management such as administration and monitoring increase the propensity of nurses to commit medication errors during clinical practice. The present training program was conducted with an aim to sensitize and educate undergraduate nursing students on medication errors' related aspects. Methods: The participants were students pursuing bachelors nursing degree course (second and third year). The training "Medication errors: Role of Nurse practitioners" comprised of blended teaching methods such as theme lectures, hands on training exercises, small group case‑based learning, role plays, and nursing officer's practical experiences. The participants' knowledge and perception about medication errors were assessed at baseline (pre-intervention phase) and 1 week after program (post-intervention phase) with the help of a structured self-administered questionnaire in English language. Results: A total of 110 nursing students participated in the program. Post program there was a consistent increase in the number of correct responses to all knowledge-based questions with a significant improvement in knowledge scores from baseline [Baseline: (mean ± SD) 12.62 ± 2.33; Post-training: 18.52 ± 2.22; P < .001]. There was a positive change in the perception about medication errors among students. The participants rated the overall quality of program as excellent [66 (60%)] or very good [40 (36.4%)]. More than 90% agreed on its applicability in their future practice. Conclusions: The training was quite successful in educating nursing students on medication errors. There is a constant need to educate nurses and other healthcare providers including doctors and pharmacists on medication safety related aspects with an ultimate goal to improve patient safety.

The Availability of Essential Antimicrobials in Public and Private Sector Facilities: A Cross-Sectional Survey in a District of North India. Antibiotics (Basel) 2024; 13:131. [PMID: 38391517 PMCID: PMC10886159 DOI: 10.3390/antibiotics13020131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Revised: 12/18/2023] [Accepted: 12/28/2023] [Indexed: 02/24/2024] Open
Abstract
(1) Background: There is a need to assess the availability of essential antimicrobials, as the availability of an antimicrobial is a critical element of its rational use. We aimed to assess the availability of antimicrobials listed in the National List of Essential Medicines 2015, India (primary list), and a selected (secondary) list comprised of agents indicated for commonly encountered infectious illnesses in various healthcare settings and to identify the reasons for their non-availability. (2) Methods: A cross-sectional survey of 25 public, private, and other sector pharmacies was carried out in Rohtak, a district of the North Indian state of Haryana, from April to June 2022. (3) Results: Most of the antimicrobials surveyed were optimally available in various sector pharmacies with the exception of benzathine benzylpenicillin, benzylpenicillin, cloxacillin, cefazolin, cefuroxime, cefadroxil, amphotericin B, and antimalarials. The most frequent reasons for limited availability were low demand, no prescriptions, and the non-listing of drugs in the state's essential medicine list. (4) Conclusions: Enough evidence needs to be generated with respect to the status of availability of essential antimicrobials from different regions of India as well as other lower-middle-income countries to devise measures for ascertaining better availability of these agents, especially antibiotics at regional, national, and global scales.

Drug Utilization Research and Predictors of Outcomes in the Intensive Care Unit of a Tertiary Care Hospital: A Prospective Observational Study. Cureus 2023; 15:e50653. [PMID: 38229777 PMCID: PMC10790238 DOI: 10.7759/cureus.50653] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/16/2023] [Indexed: 01/18/2024] Open
Abstract
BACKGROUND Multiple drugs are commonly prescribed to intensive care unit (ICU) patients owing to the disease profile, multiple organ dysfunction, prophylaxis, management of stress ulcers, nosocomial infections, etc. This study aimed to evaluate the drug utilization patterns and factors influencing mortality and duration of stay in ICU patients. Methodology: A prospective observational study was conducted in the ICU of our tertiary care hospital, Postgraduate Institute of Medical Sciences, Rohtak. Data was collected from treatment charts of patients using a structured pretested proforma. World Health Organization Anatomical Therapeutic Chemical/Defined Daily Dose (WHO ATC/DDD) methodology and core prescribing indicators were used to assess drug utilization data. The effect of different variables on mortality and duration of stay in the ICU was evaluated using regression analysis. RESULTS An average of 8.78 drugs were prescribed per patient. Among the 922 prescriptions, anti-infectives, anti-inflammatory drugs, and drugs acting on the gastrointestinal tract were the most frequent medication classes prescribed. Polypharmacy and trade name prescribing were common. For most of the drugs, the prescribed daily dose corresponded to the WHO-DDD except ceftriaxone and levofloxacin. Age, presence of cardiac disorders, and Glasgow Coma Scale (GCS) score at admission directly correlated with mortality while the use of diuretics had a negative correlation with the duration of ICU stay. Conclusions: There is a need to rationalize drug therapy in the ICU with regard to limiting polypharmacy and emphasizing generic drug name prescribing and adherence to the essential drug list. Antibiotic prescription patterns, in particular, deserve a special focus keeping in mind the multitude of factors demanding aggressive antibiotic use in critically ill intensive care patients.

[PMID: 37887197 DOI: 10.3390/antibiotics12101496] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 09/15/2023] [Accepted: 09/25/2023] [Indexed: 10/28/2023] Open
Abstract
(1) Background: Understanding the physicians' knowledge, attitudes, and antimicrobial prescribing behavior is a crucial step towards designing strategies for the optimal use of these agents. (2) Methods: A cross-sectional online survey was conducted among clinicians across India between May and July 2022 using a self-administered questionnaire in English comprising 35 questions pertaining to demographic characteristics, knowledge, attitude, and practices domains. (3) Results: A total of 544 responses were received from 710 physicians contacted. Sixty percent of participants were males, with mean age of 34.7 years. Mean ± Standard Deviation scores for knowledge, attitude, and practices domains were 8 ± 1.6, 20.2 ± 3.5, and 15.3 ± 2.1, respectively. Higher scores were associated with basic [odds ratio (95% Confidence Interval), p value: 2.95 (1.21, 7.2), 0.02], medical and allied sciences [2.71 (1.09, 6.67), 0.03], and central zone [3.75 (1.39, 10.12), 0.009]. A substantial proportion of dissatisfactory responses were found regarding hospital antibiograms, antibiotics effective against anaerobes, WHO AWaRe (access, watch, and reserve) classification of antibiotics, and the role of infection prevention and control (IPC) measures in the containment of antimicrobial resistance (AMR). (4) Conclusions: There is a need to sensitize and educate clinicians on various issues related to antimicrobial use, such as antibiograms, double anaerobic cover, IPC practices, and guideline-based recommendations, to curb the AMR pandemic.

[PMID: 37080820 DOI: 10.1016/j.idh.2023.03.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 02/08/2023] [Accepted: 03/21/2023] [Indexed: 04/22/2023]
Abstract
BACKGROUND Nurses, the largest group among healthcare professionals, hold a pivotal position to positively influence antimicrobial management by virtue of being in constant touch with patients and their widespread engagement in multiple activities relating to antimicrobial use. However, the existing gap in nursing curriculum particularly in areas related to antimicrobial resistance and optimal use of these agents limits the clinical application of nurses' skills and pose barrier to their contribution towards achieving desirable outcomes in patient care. This training program was conducted to increase the nurses' awareness on antimicrobial resistance (AMR) and sensitize them on their role in optimal antimicrobial management and stewardship activities. METHODS Training comprised of 4 modules focussing on topics like key concepts on antimicrobials, AMR, infection prevention and control, antibiotic allergy, optimal use of antibiotics and antimicrobial stewardship (AS). The participants' knowledge at baseline and 1 week after program were assessed. RESULTS AND CONCLUSIONS 190 nurses participated in the program. Post program there was a consistent increase in the number of correct responses to all knowledge-based questions pertaining to 4 modules. A significant improvement in knowledge scores for all modules from baseline was also seen. The participants rated the overall quality of program as very good and agreed on its applicability in their practice. The training program was quite successful in educating nurses on critical issues related to AMR and AS. Nurses need to be constantly trained and sensitized for their potential contributions in the field of AMR and stewardship.

Abstract
Background Health literacy plays an important role in determining healthcare and medication outcomes. There is a lack of an appropriate, validated scale to assess health literacy status among the Hindi-speaking population. We translated and validated the English version of the All Aspects of Health Literacy Scale (AAHLS) into Hindi. Methods We translated the scale as per WHO guidelines on translation and adaptation of instruments. We did preliminary pilot testing in 30 bilingual subjects and evaluated cross-language concordance of the scale. The final translated scale so obtained after cross-cultural adaptation was tested in a validation study on 130 subjects from the outpatient department of internal medicine in which test-retest repeatability, construct validity, discriminant validity and internal consistency were assessed. Analysis was done using paired t-test, one-way ANOVA, Cronbach α and intra-class correlation coefficient. Results An excellent correlation between Hindi and English versions of the scale for various factors ensured cross-language concordance. Hundred percentage response rate was observed in the validation study. The scale showed good internal consistency (Cronbach α=0.99). The difference in total mean AAHLS score was not statistically significant across different age groups, genders and educational levels. Factor analysis showed a positive correlation among four factors/components of health literacy. For test-retest reliability, the intra-class correlation coefficient for all the items in different factors was significant (range 0.88-1.00; p<0.0001). Significant association of critical literacy sub-scores with functional (r=0.274, p=0.002) and communicative (r=0.283, p=0.001) sub-scores revealed a good construct validity. Conclusion The Hindi translated version of the AAHLS scale is a valid and reliable tool to assess health literacy in the Hindi-speaking population.

Abstract
Data on Point Prevalence Surveys (PPSs) in India are limited yet. We report findings of a PPS conducted in a core "National Antimicrobial Consumption Network site" under National Centre for Disease Control - WHO project "Point prevalence survey of antimicrobial consumption at healthcare facilities." A cross-sectional survey was conducted as per the "WHO methodology for PPS on antibiotic use in hospitals" in a tertiary care hospital in India in December 2021. Data were collected using predesigned and pretested questionnaire in separate hospital, ward, and patient forms. Eight hundred two inpatients (excluding ICUs) were covered out of whom 299 (37.3%) were on antibiotics with 11.7% receiving 3 or more antibiotics. Surgical prophylaxis (SP) (42.5%) and community acquired infections (32.8%) were the most common indications for antibiotic use. Of the patients, 92.5% received SP for more than 24 hrs. Most commonly prescribed antibiotics were penicillins with beta-lactamase inhibitors (22.3%). Of the total antibiotic prescriptions, 81.5% were from WHO essential medicines list and 12% from "not recommended" WHO AWaRe classification. Of the antibiotic prescriptions, 84.6% were parenteral. Few prescriptions complied with standard treatment guidelines (1.9%), documented indication for antibiotic use (11.6%), and stop/review date (4.4%) in notes. Double anaerobic cover accounted for 6.8% of the total prescriptions. Some identified areas for improvement were: formulation of hospital antibiotic guidelines, promoting culture of sending cultures, improvement in surgical antibiotic prophylaxis, decreasing use of antibiotic combinations and double anaerobic cover, fostering IV to oral switch of antibiotics, and ensuring effective communication among health care workers by documenting adequate information in medical notes.

Abstract
BACKGROUND Erectile dysfunction(ED) in men is a frequent under-reported complication of diabetes mellitus, which is becoming significant health problem worldwide. AIMS The study aims to determine the prevalence and risk factors for development of ED in North Indian patients with type 2 diabetes mellitus. METHODS We used international index of erectile function (IIEF-5) for the assessment of ED in 796 patients with type 2 diabetes mellitus. We recorded the age, duration of diabetes, glycemic status, body mass index, diabetes medications, microvascular and macrovascular complications. RESULTS The mean age of patients in the study was 49.38 ± 9.52 years. The prevalence of ED in patients with type 2 diabetes mellitus was 79.4%. Logistic regression analysis revealed that age, body mass index, glycemic control, insulin therapy, retinopathy and nephropathy was not significantly associated with erectile dysfunction in patients with type 2 diabetes mellitus. Duration of diabetes (OR = 1.054, 95% CI 1.007 to 1.102, P=0.023) and vibration perception threshold (OR = 1.071, 95% CI 1.042 to 1.102, P=0.000) were identified as key risk factors for development of ED. CONCLUSION Duration of diabetes and peripheral neuropathy emerged as significant risk factors for development of severe erectile dysfunction.

Repurposing old molecules for new indications: Defining pillars of success from lessons in the past. Eur J Pharmacol 2021; 912:174569.

Abstract
Drug repurposing or studying existing drugs for potential therapeutic utility in newer indications has been identified as an attractive option for treating a number of diseases. Various strategies of drug repurposing include serendipitous observation of drug's unexpected effects, directing the failed investigational drugs to new indications and currently adopted systematic approach to identify, screen and develop existing drug molecules for new off-label indications. Drug repurposing is able to constructively overcome the bottleneck restraints encountered during traditional de novo drug development process in grounds of timelines, cost and resources. However, success rates of drug repurposing programs are not very impressive. Through a meticulous examination of some failed repurposing attempts we aimed to identify key factors leading to high attrition rate in such studies. Based on the fundamental elements of knowledge and evaluation, we have defined four pillars toward improving success rate in drug repurposing programs viz. sound knowledge of the repurposed drug's pharmacological characteristics (pillar 1: drug pharmacology); drug formulation considerations in new indication (pillar 2: drug formulation); evaluation in representative biological assays with translational potential (pillar 3: evaluation in biological assays); and robust clinical trial methodologies including biomarker driven approach to provide conclusive evidence of repurposed drug's efficacy in new indication (pillar 4: clinical evaluation). In addition to the pharmacological challenges, certain regulatory concerns, including lack of clear guidelines for evaluation and market exclusivity pose hurdles in the application of drug repurposing, which may however be overcome to a great extent by adopting some strategies as discussed in this review.

Abstract
BACKGROUND Being a nonbenzodiazepine, zolpidem is believed to have a favorable side-effect profile and is widely prescribed for insomnia. However, in the past few years, numerous neuropsychiatric adverse reactions, particularly complex sleep behaviors (CSBs), have been reported with zolpidem. OBJECTIVE To conduct a systematic review of zolpidem-associated CSBs. DATA SOURCES An electronic search was conducted using MEDLINE, Embase, PubMed, and Cochrane database of systematic reviews to extract relevant articles till July 2020. STUDY ELIGIBILITY CRITERIA Any type of literature article (case report, case series, and observational or interventional study) reporting CSBs associated with zolpidem. RESULTS In this review, we present aggregate summarized data from 148 patients presenting with zolpidem-induced CSBs (79 patients from 23 case reports and 5 case series; 69 patients out of 1454 taking zolpidem [4.7%] from three observational clinical studies). Various types of CSBs associated with zolpidem were reported, most common being sleepwalking/somnambulism and sleep-related eating disorder. On causality assessment, around 88% of cases were found to have a probable association with zolpidem. LIMITATIONS Extraction of data from observational studies and spontaneous reports, due to nonavailability of any randomized controlled trials relevant to the study objective. CONCLUSION AND IMPLICATION OF KEY FINDINGS Zolpidem-induced CSBs, although not very common, may develop when the drug is used at therapeutic doses for insomnia. Doctors need to be alert to monitor such adverse effects of zolpidem and exercise caution while prescribing it.

Abstract
Type 2 diabetes mellitus is an independent risk factor for renal impairment, developing in due course to end-stage kidney disease (ESKD). Such progressive renal damage is related to an increased predisposition to cardiovascular events and mortality. Even with intensive glycemic control and use of nephro-protective renin angiotensin system (RAS) blockers, rise in the worldwide prevalence of diabetic kidney disease remains tenacious. Identifying drugs with potential to halt progressive renal damage is the pressing priority at present. Sodium glucose cotransporter 2 (SGLT2) inhibitors, by virtue of their glucose-lowering and additional pleotropic effects, such as weight reduction, blood pressure lowering, anti-inflammatory, anti-fibrotic effects etc. are postulated to affect systemic and intrarenal hemodynamic mechanisms in a favorable manner which ultimately contribute to beneficial processes in the kidney. The promising reno-protective efficacy of these drugs is further highlighted by a reduction in development/progression of albuminuria and stabilization of renal function associated with their use. In particular, recent cardiovascular and kidney disease focused outcome trials have effectively demonstrated reduced rates of ESKD and other hard renal end-points, including doubling of serum creatinine, renal transplantation, death due to renal causes etc. with SGLT2 inhibitors. In this review, we dig further deep into the proposed reno-protective benefit furnished by this class of drugs by summarizing the evidence generated from clinical trials and large real-world studies. Current guideline recommendations and probability of reno-protection being influenced by factors, such as diabetic status, baseline renal function, RAS blockade is also explored to discuss their intended use in clinical settings.

Abstract
Repurposed drugs like hydroxycloroquine (HCQ) and chloroquine (CQ) are being tested for potential therapeutic role in COVID-19. We aimed to evaluate efficacy and safety of HCQ and CQ in COVID-19. Using PubMed, EMBASE, medRxiv, Google Scholar, clinicaltrials.gov, electronic search was carried out to identify relevant articles till June 2020 with re-evaluation in last week of November 2020. Observational and interventional clinical studies comparing efficacy of CQ or HCQ to standard management or other drug/s for SARS-CoV-2 infection patients were included. Cochrane review manager version 5.3 was used for synthesis of meta-analysis results. For randomized controlled trials, risk of bias was assessed using Cochrane Collaboration risk of bias assessment tool, version 2.0 (ROB-2). ROBINS-I was used for quality assessment of observational studies. Overall evidence quality generated by review was graded as per GRADE Recommendation. A total of 903 studies were screened. Nineteen studies were included in synthesis of meta-analysis with total of 4,693, 1,626, and 6,491 patients in HCQ/CQ, HCQ/CQ + AZ and control groups, respectively. HCQ/CQ treatment was associated with significantly increased rates of virological cure (OR = 2.08, 95%CI = 1.36-3.17; P = 0.0007) and radiological cure (OR = 3.89, 95%CI = 1.35 - 11.23; P = 0.01) compared to control. HCQ/CQ had no difference in unadjusted mortality rate (unadjusted OR = 0.98 95% CI = 0.70-1.37, P = 0.89, random effect model) and adjusted hazard ratio for mortality (adjusted HR = 1.05, 95%CI = 0.86--1.29; P = 0.64). However, a significant increase in odds of disease progression (OR = 1.77, 95%CI = 1.46-2.13; P < 0.00001) and QT prolongation (OR = 11.15, 95%CI = 3.95-31.44; P < 0.00001) was noted. The results with HCQ/CQ and azithromycin combination were similar to HCQ/CQ mono-therapy. In the light of contemporary evidence on effectiveness of HCQ/CQ, judicious and monitored use of HCQ/CQ for treatment of COVID-19 patients is recommended in low to middle income countries with emphasis on no mortality benefit. Registration number of Systematic review. Register in PROSPERO database: cRD42020187710.

Abstract
In an effort to curb the global pandemic due to coronavirus, the scientific community is exploring various treatment strategies with a special emphasis on drug repurposing. Ivermectin, an anti-helminthic drug is also being proposed for treatment and prevention of COVID-19. Ivermectin has demonstrated broad spectrum antiviral activity against both DNA and RNA viruses. Due to its potential to interfere with transport of SARS-CoV-2 nucleocapsid protein to nucleus, it is being proposed to have antiviral activity against this virus as well which has been confirmed in an in-vitro study. However, in-vitro to in-vivo extrapolation studies indicate an inability to achieve the desired IC50 levels of ivermectin after oral administration of doses up to 10 times higher than the approved anti-helminthic dose. In a modelling simulation study, drug accumulation in the lungs was noticed at levels having potential antiviral activity. It is hypothesised that inhaled formulation of ivermectin may be effective against SARS-CoV-2. Therefore, ivermectin administered via inhalational route needs to be explored for potential beneficial role in COVID-19 in preclinical and clinical studies. We also hypothesise the possibility of drug having anti-inflammatory action in coronavirus associated severe respiratory illness based on few in-vitro and in-vivo reports which however needs to be confirmed clinically.

Abstract
INTRODUCTION There is a paucity of literature related to the prevalence of Paroxysmal Nocturnal haemoglobinuria (PNH) clones in paediatric aplastic anaemia (AA) patients. METHODS We performed a retrospective analysis over a period of 42 months to study the prevalence of PNH clones in paediatric (age less than 18 years) AA cases, using Fluorescein-labelled proaerolysin-based flow cytometric screening and analysed their clinico-pathological features. RESULTS PNH clone was identified in 100 (33.2%) of the 301 patients screened. These were comprised of 51 cases of non-severe AA, 33 cases of severe AA and 16 cases of very severe AA. The median age was 13 years with an M:F ratio of 2.5:1. The median clone size (taken as the proportion of PNH-positive neutrophils) was 2.15% (range: 0.05%-93.1%). Although a majority of patients (n = 77) had a clone size of less than 10%, a significant proportion (n = 23) did harbour a clone size of more than 10%. Evidence of haemolysis was observed in 3 patients, all of them having a clone size of more than 10%. Interestingly, 1 patient with dural sinus thrombosis harboured a clone size of 1.25% only. Chromosomal breakage analysis was performed in 61 patients, none of which was positive. Complete and partial response to immunosuppressive therapy was found in 55.1% patients (16/29). CONCLUSION There is a high prevalence of PNH clones in paediatric AA patients, which in a majority of cases are of small clone sizes. The use of immunosuppressive therapy does not show a better outcome as compared to PNH-negative cases.

Abstract
Aims The aims of this study were to establish whether composite fixation (rail-plate) decreases fixator time and related problems in the management of patients with infected nonunion of tibia with a segmental defect, without compromising the anatomical and functional outcomes achieved using the classical Ilizarov technique. We also wished to study the acceptability of this technique using patient-based objective criteria. Patients and Methods Between January 2012 and January 2015, 14 consecutive patients were treated for an infected nonunion of the tibia with a gap and were included in the study. During stage one, a radical debridement of bone and soft tissue was undertaken with the introduction of an antibiotic-loaded cement spacer. At the second stage, the tibia was stabilized using a long lateral locked plate and a six-pin monorail fixator on its anteromedial surface. A corticotomy was performed at the appropriate level. During the third stage, i.e. at the end of the distraction phase, the transported fragment was aligned and fixed to the plate with two to four screws. An iliac crest autograft was added to the docking site and the fixator was removed. Functional outcome was assessed using the Association for the Study and Application of Methods of Ilizarov (ASAMI) criteria. Patient-reported outcomes were assessed using the Musculoskeletal Tumor Society (MSTS) score. Results The mean age of patients was 38.1 years (sd 12.7). There were 13 men and one woman. The mean size of the defect was 6.4 cm (sd 1.3). the mean follow-up was 33.2 months (24 to 50). The mean external fixator index was 21.2 days/cm (sd 1.5). The complication rate was 0.5 (7/14) per patient. According to the classification of Paley, there were five problems and two obstacles but no true complications. The ASAMI bone score was excellent in all patients. The functional ASAMI scores were excellent in eight and good in six patients. The mean MSTS composite score was 83.9% (sd 7.1), with an MSTS emotional acceptance score of 4.9 (sd 0.5; maximum possible 5). Conclusion Composite fixation (rail-plate) decreases fixator time and the associated complications, in the treatment of patients of infected nonunion tibia with a segmental defect. It also provides good anatomical and functional results with high emotional acceptance. Cite this article: Bone Joint J 2018;100-B:1094-9.

Sex-specific ultrasonic vocalization patterns and alcohol consumption in high alcohol-drinking (HAD-1) rats. Physiol Behav 2017; 203:81-90. [PMID: 29146494 DOI: 10.1016/j.physbeh.2017.11.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2017] [Revised: 10/03/2017] [Accepted: 11/12/2017] [Indexed: 12/29/2022]
Abstract
Ultrasonic vocalizations (USVs) have been established as an animal model of emotional status and are often utilized in drug abuse studies as motivational and emotional indices. Further USV functionality has been demonstrated in our recent work showing accurate identification of selectively-bred high versus low alcohol-consuming male rats ascertained exclusively from 22 to 28kHz and 50-55kHz FM USV acoustic parameters. With the hypothesis that alcohol-sensitive sex differences could be revealed through USV acoustic parameters, the present study examined USVs and alcohol consumption in male and female selectively bred high-alcohol drinking (HAD-1) rats. For the current study, we examined USV data collected during a 12-week experiment in male and female HAD-1 rats. Experimental phases included Baseline (2weeks), 4-h EtOH Access (4weeks), 24-h EtOH Access (4weeks) and Abstinence (2weeks). Findings showed that both male and female HAD-1 rats spontaneously emitted a large number of 22-28kHz and 50-55kHz FM USVs and that females drank significantly more alcohol compared to males over the entire course of the experiment. Analyses of USV acoustic characteristics (i.e. mean frequency, duration, bandwidth and power) revealed distinct sex-specific phenotypes in both 50-55kHz FM and 22-28kHz USV transmission that were modulated by ethanol exposure. Moreover, by using a linear combination of these acoustic characteristics, we were able to develop binomial logistic regression models able to discriminate between male and female HAD-1 rats with high accuracy. Together these results highlight unique emotional phenotypes in male and female HAD-1 rats that are differentially modulated by alcohol experience.

Abstract
Background: Sodium glucose co-transporter 2 inhibitors represent a novel class of antidiabetic drugs. The reporting quality of the trials evaluating the efficacy of these agents for glycemic control in type 2 diabetes mellitus has not been explored. Our aim was to assess the reporting quality of such randomized controlled trials (RCTs) and to identify the predictors of reporting quality. Materials and Methods: A systematic literature search was conducted for RCTs published till 12 June 2014. Two independent investigators carried out the searches and assessed the reporting quality on three parameters: Overall quality score (OQS) using Consolidated Standards of Reporting Trials (CONSORT) 2010 statement, Jadad score and intention to treat analysis. Inter-rater agreements were compared using Cohen's weighted kappa statistic. Multivariable linear regression analysis was used to identify the predictors. Results: Thirty-seven relevant RCTs were included in the present analysis. The median OQS was 17 with a range from 8 to 21. On Jadad scale, the median score was three with a range from 0 to 5. Complete details about allocation concealment and blinding were present in 21 and 10 studies respectively. Most studies lacked an elaborate discussion on trial limitations and generalizability. Among the factors identified as significantly associated with reporting quality were the publishing journal and region of conduct of RCT. Conclusions: The key methodological items remain poorly reported in most studies. Strategies like stricter adherence to CONSORT guidelines by journals, access to full trial protocols to gain valuable information and full collaboration among investigators and methodologists might prove helpful in improving the quality of published RCT reports.

Abstract
A 74-year-old female with trigeminal neuralgia developed hypertension after the initiation of carbamazepine therapy. The time sequence of start of the suspected drug and onset of hypertension are consistent with the diagnosis. The hypertension did not resolve with antihypertensive therapy or dose reduction of carbamazepine. Patient recovered after the carbamazepine therapy was discontinued. The positive rechallenge and positive dechallenge showed association of carbamazepine therapy with hypertension as its adverse effect. This is a rare case that we report of carbamazepine-induced hypertension and this report may act as alerting mechanism to the health care professionals especially neurologists.

Abstract
UNLABELLED von Willebrand disease (VWD), an inherited bleeding disorder caused by deficiency or dysfunction of von Willebrand factor (VWF) is diagnosed when a personal and often a family history of excessive mucocutaneous bleeding is present along with abnormal laboratory studies. An accurate assessment of haemorrhagic symptoms is key in suspecting VWD but presents a challenge especially in children due to overlap between normal and abnormal bleeding. Bleeding questionnaire (BQ) scores have been validated in adults and have recently been validated in children with VWD for assessing bleeding severity. However, there are limited data supporting their use prospectively in healthy children with bleeding complaints. AIM The objectives of this study were to obtain normative data from children and validate a paediatric BQ (PBQ) to determine the discriminative ability of its total score and its individual components for identifying children likely to have VWD. METHODS The PBQ was administered to 1281 multiethnic, healthy children between 30 days and 18 years of age presenting to a general paediatric office and to 35 children with VWD based on VWF antigen, activity and multimer pattern. RESULTS When children with total BQ scores of 3 or more were predicted to have VWD, the sensitivity was 97.2%, the specificity was 97.1%, the positive predictive value was 48.6% and the negative predictive value was 99.9%. CONCLUSIONS The PBQ may help discriminate a significant bleeding history from trivial bleeding, may be integrated into the primary care algorithm for evaluating children suspected with VWD.

Abstract
In order to develop climate resilient urban areas and reduce emissions, several opportunities exist starting from conscious planning and design of green (and blue) spaces in these landscapes. Green urban infrastructure has been regarded as beneficial, e.g. by balancing water flows, providing thermal comfort. This article explores the existing evidence on the contribution of green spaces to climate change mitigation and adaptation services. We suggest a framework of ecosystem services for systematizing the evidence on the provision of bio-physical benefits (e.g. CO2 sequestration) as well as social and psychological benefits (e.g. improved health) that enable coping with (adaptation) or reducing the adverse effects (mitigation) of climate change. The multi-functional and multi-scale nature of green urban infrastructure complicates the categorization of services and benefits, since in reality the interactions between various benefits are manifold and appear on different scales. We will show the relevance of the benefits from green urban infrastructures on three spatial scales (i.e. city, neighborhood and site specific scales). We will further report on co-benefits and trade-offs between the various services indicating that a benefit could in turn be detrimental in relation to other functions. The manuscript identifies avenues for further research on the role of green urban infrastructure, in different types of cities, climates and social contexts. Our systematic understanding of the bio-physical and social processes defining various services allows targeting stressors that may hamper the provision of green urban infrastructure services in individual behavior as well as in wider planning and environmental management in urban areas.

Abstract
BACKGROUND The present study of 238 B-cell Chronic Lymphocytic Leukemia (B-CLL) patients were undertaken to seek the prevalence and to evaluate clinico-pathological significance of recurrent genetic abnormalities such as del(13q14.3), trisomy 12, del(11q22.3) (ATM), TP53 deletion, del(6q21) and IgH translocation/deletion. MATERIALS AND METHODS We applied interphase - fluorescence in situ hybridization (FISH) on total 238 cases of B-CLL. RESULTS Our study disclosed 69% of patients with genetic aberrations such as 13q deletion (63%), trisomy 12 (28%), 11q deletion (18%), 6q21 deletion (11%) with comparatively higher frequency of TP53 deletion (22%). Deletion 13q displayed as a most frequent sole abnormality. In group with coexistence of ≥2 aberrations, 13q deletion was a major clone indicating del(13q) as a primary event followed by 11q deletion, TP53 deletion, trisomy 12, 6q deletion as secondary progressive events. In comparison with del(13q), trisomy 12, group with coexistence of ≥2 aberrations associated with poor risk factors such as hyperleukocytosis, advanced stage, and multiple nodes involvement. In a separate study of 116 patients, analysis of IgH abnormalities revealed either partial deletion (24%) or translocation (5%) and were associated with del(13q), trisomy 12, TP53 and ATM deletion. Two of 7 cases had t(14;18), one case had t(8;14), and four cases had other variant IgH translocation t(?;14). CONCLUSION Detail characterization and clinical impact are necessary to ensure that IgH translocation positive CLL is a distinct pathological entity. Our data suggests that CLL with various cytogenetic subsets, group with coexistence of ≥2 aberrations seems to be a complex cytogenetic subset, needs more attention to understand biological significance and to seek clinical impact for better management of disease.

Abstract
Background: One of the postulated mechanism for cardioprotective potential of isoflavones is their ability to exert antioxidant action. However, various reports give conflicting results in this area. Aim: The present study was conducted with an objective to probe into the cardioprotective mechanism of isoflavones by evaluating their antioxidant potential in oophorectomized women. Materials and Methods: This was a randomized, double-blind, parallel, placebo controlled study. A total of 43 women were randomized to receive 75 mg/day isoflavones tablet or placebo for 12 weeks. Red blood cell antioxidant parameters including lipid peroxidation, superoxide dismutase (SOD), catalase and glutathione peroxidase (GSH-Px) were determined at baseline and at the end of the study. Results: After 12 weeks of administration of isoflavones, there was no statistically significant difference in lipid peroxidation (P value for isoflavones: 0.37; for placebo: 0.37), catalase (P value for isoflavones: 0.35; for placebo: 0.84), SOD (P value for isoflavones: 0.41; for placebo: 0.28) and GSH-Px (P value for isoflavones: 0.92; for placebo: 0.29). There was no statistically significant difference in the proportion of patients experiencing adverse events in the two groups (P -1.00). Conclusion: The study strengthens the concept that the cardioprotective mechanism of isoflavones might be due to some other reason apart from the antioxidant pathway.

Abstract
CONTEXT Medication-related adverse events, apart from causing significant morbidity and mortality, increase the healthcare cost burden and lead to early treatment discontinuations. OBJECTIVES Knowing the fact that cutaneous adverse drug reactions (cADRs) are most frequent, this study was conducted with an aim to describe their clinical profiles and preventive strategies. METHODS All adverse drug reaction (ADR) forms filled from January 2012 to January 2013 were scrutinised and forms with cADRs analysed and assessed for causality, preventability and severity. RESULTS Of 400 ADR forms, 109 included cADRs. Sixty-eight percent patients were males and mean ± SD age was 35 ± 18 years. Rash, Steven-Johnson syndrome and toxic epidermal necrolysis were the most common presentations. Most frequent culprit drugs included antibiotics and anti-inflammatory agents. Causality was probable or possible in majority. Ninety percent cases were "not preventable". Majority of the patients had mild to moderate reactions and recovered completely after medical management. CONCLUSIONS Pharmacovigilance, with special attention to monitoring and reporting of cADRs must be encouraged. As major bulk of cADRs result from physician prescribed drugs, awareness on part of the physician can help in their timely detection and management, thereby restricting the associated damage.

Abstract
Drug therapy accounts for a major portion of health expenditure. A useful strategy for achieving cost efficient healthcare is drug utilisation research as it forms the basis for making amendments in drug policies and helps in rational drug use. The present observational study was conducted to generate data on drug utilization in inpatients of our tertiary care hospital to identify potential targets for improving drug prescribing patterns. Data was collected retrospectively from randomly selected 231 medical records of patients admitted in various wards of the hospital. WHO Anatomical Therapeutic Chemical/Defined Daily Dose methodology was used to assess drug utilisation data and drug prescriptions were analysed by WHO core drug indicators. Antibiotics were prescribed most frequently and also accounted for majority of drug costs. The prescribed daily dose for most of the antibiotics corresponded to defined daily dose reflecting adherence to international recommendations. Brand name prescribing and polypharmacy was very common.78% of the total drugs prescribed were from the National List of Essential Medicines 2003. Restricting the use of newer and costlier antibiotics, branded drugs and number of drugs per prescription could be considered as targets to cut down the cost of drug therapysignificantly.

Abstract
To examine the efficacy, safety and tolerability of tolterodine in children with overactive bladder in comparison with standard treatment i.e. oxybutynin as demonstrated in randomized clinical trials and other studies. A systematic search was done to screen the studies evaluating the effect of tolterodine in children with non-neurogenic overactive bladder. Results of studies were pooled and compared. Efficacy was determined from micturition diaries and dysfunctional voiding symptoms score. Safety and tolerability were assessed from the reported treatment emergent adverse events. A total of six randomized clinical trials and 11 other studies of tolterodine in children with urinary incontinence were included in the present systematic review. The dose of tolterodine used in different settings ranged from '0.5 to 8 mg/day' instead of '0.5 to 8 mg/kg per day' and the duration of studies ranged from 2 weeks to 12 months. Both extended and immediate release preparations of tolterodine were shown to have comparable efficacy and tolterodine proved to have comparable efficacy with better tolerability than oxybutynin in these studies. It can be concluded that tolterodine is efficacious in treatment of urinary incontinence in children. Moreover, its efficacy is comparable to oxybutynin, the most commonly prescribed anticholinergic in this condition, while having better tolerability. Hence, it can be considered as first line therapy for the treatmentof urinary incontinence in children.

Abstract
Objectives: Poisonings and snake bites constitute major health-care problems worldwide. This observational study was conducted to identify factors associated with outcomes in such cases and to suggest strategies to improve them. Methods: This is a prospective study conducted in the emergency medicine department of a tertiary care hospital. The study included 102 poisoning and 64 snake bite cases. Data regarding demographics, mode of poisoning, lag time in treatment, first aid, outside and indoor treatment, co-morbid illness, duration of hospitalisation and final outcome were collected in a prestructured proforma. Results: The age of the patients ranged from 11 to 68 years and incidence was more common among males (69.9%) compared to females (30.1%). The major types of poisonings included organophosphorus compounds (16.3%), aluminium phosphide (12%), drug overdose (10.8%) and corrosives (6%). There were 18 (18.6%) and 1 (1.6%) deaths in poisoning and snake bite cases, respectively. In poisoning cases, the duration of hospitalisation was significantly decreased if patient received outside treatment (p = 0.02) and if he or she had lesser lag time in reaching the hospital (p = 0.009). Conclusions: Measures to reduce lag time and provide immediate treatment at initial encounter may be effective in reducing duration of hospitalisation and possibly mortality in poisoning and snake bite cases.

Abstract
Central giant cell granuloma (CGCG) is a benign, non-odontogenic bone lesion of jaw. The condition is relatively infrequent and affects mainly children and young adults with a certain predominance among females and exhibits variable aggressiveness. Giant cell lesion associated with hyperparathyroidism is known as Brown tumor. Brown tumor is one of the bony complications of hyperparathyroidism. It is a giant cell granuloma which occurs in osteitis fibrosis cystica. It represents the terminal stage of the bone remodelling processes occurring as a result of peritrabecular fibrosis and osteoclastic activity. The mandible is the predominantly affected site in the maxillofacial area. Maxillary involvement is rare. The incidence of Brown tumor associated with hyperparathyroidism is rare (0.1%). Here, an extremely rare case of a 20 year old female patient with Brown tumor in her maxilla and mandible associated with primary hyperparathyroidism was presented. A thorough diagnostic work up showed presence of tumor mass in mandible and maxilla and elevated serum alkaline phosphatase and parathormone level and the patient was treated for both hyperparathyroidism and Brown tumor were discussed. The importance of different radiological evaluation methods and the consultation between the oral and maxillofacial surgeons, dentists, endocrinologists and radiologists were emphasized.

Abstract
Systemic mastocytosis with associated clonal hematological nonmast cell lineage disease (SM-AHNMD) is a subtype of mastocytosis associated commonly with myeloid neoplasms, Non-Hodgkin's lymphoma, or other hematological neoplasms. In these conditions, mastocytosis needs to be differentiated from mast cell hyperplasia or mast cell activation states. Neoplastic nature of mastocytosis is proved either by morphology, aberrant immunophenotype, or detection of point mutation at codon-816 of c-kit gene. This is a rare entity, even more so in pediatric population. Herein, we report a case of 14-year-old girl with SM associated with acute myeloid leukemia with maturation with t(8;21). Multifocal dense infiltrate of spindle-shaped mast cells on bone marrow aspirate and biopsy with coexpression of CD2 and CD25 by flow cytometric analysis proved the SM component at the time of diagnosis and persistence at post induction status also.

Abstract
The morphological spectrum of light chain deposition disease (LCDD) may range from normal glomerular morphology to mesangio-proliferative to mesangio-capillary to nodular sclerosing patterns. Due to the inconsistencies regarding treatment and the universally poor graft outcome of post-transplant LCDD, it is imperative to maintain a high index of suspicion and perform relevant investigations for clinching this diagnosis. A 40-year-old lady was diagnosed as a case of membrano-proliferative glomerulonephritis 3 years back, for which she underwent a live unrelated renal allograft transplant. Postoperative period was complicated by an acute rise in serum creatinine on the 21st postoperative day. Biopsy showed patchy acute cortical necrosis, which responded to conservative management. The present admission was for renal failure and subnephrotic proteinuria. A kidney biopsy was performed, and all the 14 glomeruli examined showed a mesangiocapillary pattern of glomerular injury with cellular nodule formation in some. The nodules were PAS and Congo red negative. Immunofluorescence showed glomerular and tubular basement staining for Kappa light chains only. Electron microscopy showed the characteristic granular deposits in subendothelial location in the glomerulus, and in tubular basement membranes, thus confirming the diagnosis of LCDD. Membranoproliferative pattern of glomerular injury in the pre- and posttransplant setting has a wide range of differential diagnoses; LCDD being one of them.

Abstract
INTRODUCTION Rheumatoid arthritis (RA) patients taking disease-modifying antirheumatic drugs (DMARDs) may experience treatment failure due to adverse effects or a lack of efficacy/resistance. The purpose of this study was to evaluate the prescription patterns, the incidence and reasons for failure, and the time to treatment failure of DMARDs in RA patients. METHODS The medical records of patients visiting the Rheumatology Clinic were scrutinised retrospectively in order to extract the relevant data, including demographics, clinical and laboratory investigations and drug usage, for analysis. RESULTS More than 60% of the 474 eligible patients were started on a combination of DMARDs. Hydroxychloroquine (HCQ) (79.7%) and methotrexate (MTX) (55.6%) were the most common DMARDs prescribed initially. There was a significant difference in survival times among the various treatment groups (p ≤ 0.001). Adverse effect was the main reason for treatment failure of sulfasalazine (SSZ) (88.9%) and MTX (75%), while addition or substitution DMARDs was more common for those taking HCQ (72.2%). Adverse event was reported as the most significant predictor of treatment failure. The most commonly reported adverse effects were bone marrow suppression and hepatotoxicity. CONCLUSION A combination of DMARDs was used to initiate therapy in more than 60% of RA patients, with HCQ and MTX being prescribed most frequently. Adverse effects accounted mainly for treatment failures with MTX and SSZ, while lack of efficacy was responsible for major treatment failures with HCQ.

Abstract
AIM The pharmacotherapy for heart failure with normal ejection fraction (HFNEF) is not as well defined as that for the treatment for heart failure with reduced ejection fraction (HFREF). Studies of the various drugs given for HFNEF have revealed conflicting results. The aim of this systematic review was to determine whether there is any benefit with pharmacotherapy in HFNEF in terms of cardiac outcomes. METHODS Electronic and printed sources were searched until August 2010 for randomized controlled clinical trials (RCTs) comparing drug therapy with placebo in HFNEF. Weighted mean difference and pooled odds ratio (OR) with 95% confidence intervals were calculated. RESULTS A total of six RCTs including 8410 patients with a mean follow-up period of 21 months were included in the analysis. Although there were no significant differences in all cause mortality between the two groups (pooled OR 0.95, 95% CI 0.79, 1.13, P= 0.55), the subgroup analysis revealed a slight but non significant advantage with the β-adrenoceptor blocker group. There was no significant difference between the two groups in terms of cardiovascular mortality, hospitalization, worsening heart failure, ejection fraction, E : A ratio, deceleration time and E : E' ratio. CONCLUSION There was no significant benefit of pharmacotherapy in HFNEF. This might have been because of a lack of stringent inclusion criteria for patients in the trials and lower power of the studies. Hence trials with well defined inclusion criteria, better power, longer follow-up periods and with echocardiographic parameters as endpoints are required to shed further light on this topic.

Abstract
BACKGROUND AND OBJECTIVES The potential of soy isoflavones to interfere with thyroid function has been reported. However, there are limited data regarding their effect on thyroid function and autoimmunity in surgical menopausal women. The present study aimed to evaluate the effect of isoflavones on thyroid function and autoimmunity, menopausal symptoms, serum follicle stimulating hormone (FSH) and estradiol levels in oophorectomised women. METHODS A randomized, double blind, placebo-controlled trial was conducted in 43 oophorectomised women to evaluate the effect of soy isoflavones (75 mg/day for 12 wk) on serum thyroid profile (free T3, free T4, TSH, TBG and anti-TPO antibody titres) assessed at baseline, 6 and 12 wk after randomization. Assessment was also done for menopause symptom score (MSS) three weekly, and FSH and estradiol levels at baseline and at study completion. RESULTS There was a significant alteration in free T3 levels in the group receiving isoflavones (4.05 ± 0.36, 4.12 ± 0.69 and 3.76 ± 0.55 pmol/l at baseline, 6 and 12 wk, respectively; P=0.02). However, the mean change in various thyroid parameters at 12 wk from baseline was not significantly different between the two groups. MSS was also significantly decreased at 9 and 12 wk from baseline with isoflavones (12.47 ± 8.15, 9.35 ± 5.23 and 9 ± 5.14 at baseline, 9 and 12 wk respectively; P=0.004) with significant improvement in urogenital symptoms compared to placebo. Isoflavones did not significantly affect other parameters during study period. There were no serious adverse events reported and the proportion of patients experiencing adverse events was similar between the two groups. INTERPRETATION AND CONCLUSIONS Modest reduction in serum free T3 levels in the isoflavone group in the absence of any effect on other thyroid parameters might be considered clinically unimportant.

The effect of prostaglandin synthase inhibitor, aspirin on the rat intestinal membrane structure and function. NUTR HOSP 2010; 25:290-298.

Abstract
Aspirin at a dose of 50 mg/kg body weight was found to decrease the activity of the rat intestinal brush border membrane (BBM) - associated enzymes such as the sucrase, lactase, maltase and alkaline phosphatase. Aspirin treatment also led to a decrease in the microviscosity in the native as well as the benzyl alcohol treated membrane which might be due to the lipid peroxidative damage in the membrane. Physical correlation of the membrane oxidative damage was evident as the Fourier Transformation Infra Red (FTIR) study of the Aspirin treated membrane, which include an increased proportion of gauche to trans conformer, shift in the methylene C-H asymmetric and symmetric stretching frequencies, C = O double bond stretching, NH bending, antisymmetric (N)-CH3 bending, C-N stretching and antisymmetric CNC stretching while there was no change in the CH2 wagging and twisting as well as in NH-bending amide bond I and II. Aspirin treatment also caused an alteration in the glucose and histidine transport, as evident by a decreased Vmax value while the apparent Km remaining unchanged in the control and Aspirin-treated animals confirming that there was no change in the substrate affinity constant of the membrane transport proteins for the glucose and the basic amino acid, although the rate of transport decreased considerably. There was a decrease noted in the energy of activation of glucose and histidine transport when studied at different temperature but no change in the temperature of phase transition in the BBM with Aspirin treatment, thus implying that perhaps the thermotropic phase transition in the membrane may have relatively little effect on the transport processes. The result suggests an underlying molecular mechanism indicating the implied membrane damage by Aspirin, an important member of the non-steroidal antiinflammatory drug (NSAID) family which could possibly through an oxidative damage may lead to an altered molecular structure, physical state and biological functions of the intestinal membrane.

Abstract
The present study was planned to evaluate the role of curcumin in the formalin-induced orofacial pain in rats that mimics typical human orofacial pain. Adult Wistar rats of either sex received an injection of 50 microL of 5% v/v subcutaneous formalin injection into one vibrissal pad and consequent facial grooming behavior was monitored. Animals exhibited two distinct periods of nocifensive grooming: (a) an acute phase lasting 0-6 min; and (b) a tonic phase lasting 6-45 min. The analgesic response of curcumin was observed at doses of 25, 50, 100, 200, 400 and 600 mg/kg i.p., administered 15 min prior to formalin injection. Another group received subanalgesic dose of diclofenac (0.2 mg/kg) and curcumin 25 mg/kg. Curcumin and diclofenac were administered 15 and 5 min prior to formalin injection respectively. Curcumin produced a dose-dependent inhibition of facial grooming in both acute and tonic phases compared to vehicle and potentiated the subanalgesic dose of diclofenac. The study results for the first time demonstrated the per se antinocifensive effect of curcumin and also exhibited a synergistic interaction with the subanalgesic dose of an NSAID in the facial pain model. More studies are necessary to elucidate the mechanisms of curcumin in this model of pain.

Abstract
The present study was designed to evaluate the effects of three non-steroidal anti-inflammatory drugs (NSAIDs) with varying cycloxygenase selectivities on the small intestinal biochemical composition, function and histology during 1, 2-dimethylhydrazine (DMH) administration. Sprague Dawley male rats were divided into five different groups viz: Group 1 (control, vehicle treated), Group 2 (DMH-treated, 30 mg/kg body weight/week in 1 mM EDTA-saline, subcutaneously), Group 3 (DMH + aspirin-60 mg/kg body weight), Group 4 (DMH + celecoxib-6 mg/kg body weight), Group 5 (DMH + etoricoxib-0.64 mg/kg body weight). After six weeks of treatment, brush border membrane was isolated from the jejunum segment of all the groups and changes in the associated enzymes such as sucrase, lactase, maltase, alkaline phosphatase, membrane lipid composition, fluorescence polarizations of diphenylhexatriene, pyrene excimer formation, histological changes and surface characteristics were studied. The results indicated a significant alteration in the enzyme activity as well as changes in the structure and function of the intestine in the presence of the pro-carcinogen, DMH, which suggests the possible chemopreventive efficacy of NSAIDs against the intestinal cancer.
