Abstract
Control of pain in patients with chronic pancreatitis is difficult because 30.0% to 50.0% of patients still experience persistence or recurrence of pain even after surgery. So a combined approach of surgery and coeliac plexus neurolysis was carried out in this study to see the relief of pain and reduce the requirement of analgesics in these patients. This prospective observational comparative study was carried out in the Department of Hepatobiliary, Pancreatic and Liver Transplant Surgery in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from November 2017 to October 2018. Forty one (41) study participants with the diagnosis of chronic pancreatitis were included consecutively in this study. The participants were divided into two groups. Group I (n=18) underwent pancreatic surgery with coeliac plexus neurolysis by infiltration of 20ml of 100% alcohol in the loose areolar tissue 10ml each into right and left para-aortic space at the level of coeliac trunk and Group II (n=23) underwent pancreatic surgery only. Participants' preoperative data were collected from patient record file. Number, frequency and intensity of pain and requirement of amount of analgesics for the last 3 months were recorded from patients' history. The intensity of pain was categorized by visual analog scale (VAS) preoperatively. The participants of both groups were followed up at 1, 2 and 3 months interval and asked for disappearance or reduction of pain, frequency of attack and requirement of analgesics. Again visual analog scale was used for categorization of pain. Pain free period was recorded after the end of follow up period. Pain reduction occurred after surgery in both groups. But when pain relief was compared on the basis of VAS (Visual Analogue Scale), it was significantly better in Group I after 1 month of surgery than Group II (p=0.05). But 2 and 3 months after surgery this difference became insignificant (p=0.246 and 0.264). No statistical difference was found in terms of analgesic usage, severe acute attack or hospital admission (p=0.511, 0.439 and 0.495) at the end of 3 months follow up. Participants in Group I had significantly longer pain free period than Group II (p=0.025). Regarding complications, postural hypotension developed in 5.6% (1) patients. Diarrhea developed in 11.1% (2) patients in Group I and wound infection developed in 2 patients in each groups respectively. No patients developed any major complications like anastomotic leakage, deep or organ or space infection. Intraoperative coeliac plexus neurolysis reduces pain immediately after surgery and provides longer pain free period in patients with chronic pancreatitis after surgery.

Abstract
Retrieval of stone by endoscopic papillotomy, laparoscopic choledochotomy or open choledochotomy is the treatment of choice for choledocholithiasis. Published literature shows that the recurrence rate is 4% to 24% with existing method of treatment. We have treated 8 patients who admitted with recurrent choledocholithiasis in the department of Hepato-Biliary-Pancreatic and Liver Transplant Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh in the period of January 2016 to December 2019. None had intrahepatic duct abnormality or stones. All patients underwent either ERCP stenting, open choledocholithotomy or both 16 to 84 months back. Management policy is designed and outcome is observed on these patients. There were 3 males and 5 females; age ranges 18 to 60 years. The common bile duct (CBD) diameter of all patient ranges from 15 to 24mm. The shape of CBD is different from normal variant; S shaped, saculated, grossly dilated with terminal narrowing. Considering the anatomical abnormality and recurrence of disease we have removed the abnormal part of common bile duct along with stones and the operation was completed by Roux-en-Y hepaticojejunostomy. All patients were completely symptom free for 6 to 48 months after surgery. Removal of abnormal part of common bile duct with reconstruction in the form of Roux-en-Y hepatico-jejunostomy may be considered for treating choledocholithiasis with abnormal CBD (abnormally dilated, abnormally shaped, angulated or sacculated) however, long-term follow up is required for final comment.

Abstract
This study estimates the prevalence of central obesity in South Asian adults and examines gender differences in central obesity across cardiometabolic determinants. An urban community-based survey was conducted using multi-stage random sampling. Asia-Pacific criterion for waist circumference (WC) was used to measure central obesity. Amongst 1178 participants, females had a higher age-adjusted central obesity (48%), and more than two-fold increased odds of central obesity. Increased prevalence of central obesity and female preponderance are indicative for a gender-sensitive population-level intervention to tackle cardiometabolic risk. WC may be an effective population-level measurement tool for cardiometabolic risk assessment in South Asian adults.

Abstract
Objectives To estimate the prevalence and to identify potential risk factors of silent myocardial ischemia in a cohort of patients with asymptomatic type 2 Diabetes (diabetes) for early detection of coronary risk by employing objective noninvasive clinical screening tools for Subclinical Atherosclerosis. Methods The study is a clinic-based observational study on 338 consecutive diabetes patients attending an urban health center from Eastern India. The response rate was 96.57% out of 350 eligible subjects, comprising 176 (52.1%) males and 162 (47.9%) females. Clinical, anthropometric, biochemical parameters were collected in all participants. Both tools, i.e., treadmill test (TMT) to identify subjects with silent myocardial ischemia, and carotid imaging to detect subclinical atherosclerosis by evaluating carotid intima-media thickness (CIMT), were assessed. Significant determinants were predicted by multivariable logistic regression. Results The study group was divided into a TMT negative (n = 260), and a TMT positive group (n = 78). These 78 TMT positive subjects (23.1%) were identified to have silent myocardial ischemia. The prevalence of silent myocardial ischemia was more common in males (28.4%) than in females (17.3%). The mean CIMT in our study group was 0.6741 ± 0.034 mm (males – 0.684 ± 0.034 mm and females – 0.663 ± 0.032 mm). Age ≥50 years, CIMT ≥0.70 mm, hypercholesterolemia, and hypertriglyceridemia were significant determinants for identifying asymptomatic diabetics at risk for silent myocardial ischemia. Conclusion Silent myocardial ischemia is highly prevalent at about one in four asymptomatic diabetic patients. An increased CIMT can be a surrogate marker of higher coronary risk amongst these asymptomatic diabetics.

Abstract
Recurrent cholangitis and sepsis are common complications after surgical treatment for hepatolithiasis as total clearance is not always possible. This retrospective study is designed to see the effect of our treatment for hepatolithiasis on stone clearance and post operative complications. We have treated 60 patients with hepatolithiasis surgically from September 2010 to September 2016 in the Department of Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Various operative procedures were applied on the basis of location of stone and status of biliary tree. Choledocoscopic examination was performed during surgery for checking and cleaning of intrahepatic duct. Regular follow up was given and outcome was assessed. The chronological changes of treatment methods for patients with hepatolithiasis were analyzed for appropriate treatments for particular type. There were 22 males and 38 females with age ranges from 15 to 60 years. The stone were located in left duct (56.6%), right duct (10%) and both duct (33.4%). The most commonly performed operation was extended choledocholithotomy and hepatolithotomy and it was performed in 28 patients (46.7%). Segmentectomy and lobectomy was performed in 17 patients (28.3%). Common bile duct (CBD) excision, hepatolithotomy and hepaticojejunostomy with or without segmentectomy, lobectomy and Houston access loop formation was performed in rest of the patients. Stones could be removed completely in all patients who underwent lobectomy or segmentectomy. In contrast stone clearance was possible only in 57.2% and 55.5% who underwent extended choledocholithotomy and hepatolithotomy, and excision of CBD, hepatolithiasis with hepaticojejunostomy for unilateral or bilateral hepatolithiasis respectively. Houston's access loop to stomach was made in 2 patients for future endoscopic removal of stone. There was no mortality in the present series but morbidity occurred in 18 patients; wound infection (n=15, 25%), bile leakage (n=1, 1.7%), and renal dysfunction (n=1, 1.7%), septicemia (n=1, 1.7%). Patients who underwent lobectomy or segmentectomy did not develop cholangitis or sepsis on 1 to 3 years follow up. In contrast who underwent extended choledocholithotomy and hepatolithotomy, 70.8% patients developed cholangitis and sepsis, and the patients who underwent excision of CBD, hepatolithotomy with hepaticojejunostomy 50% developed cholangitis and sepsis within 1 to 3 years of follow up, required re-operations or conservative treatment. The difference of developing postoperative cholangitis and sepsis is significant (p<0.05) between patient who underwent extended choledocolithotomy and hepatolithotomy, and who underwent excision of CBD, hepatolithotomy and Roux-en-Y hepaticojejunostomy. In conclusion, lobectomy or segmentectomy is the best option for hepatolithiasis if the stones are limited to a lobe or segment. Excision of CBD, hepatolithotomy with hepaticojejunostomy is better than extended choledocholithotomy and hepatolithotomy for bilateral hepatolithiasis. Huston's access loop formation associated with other procedures may be considered for bilateral hepatolithiasis for future minimal invasive stone retrieval procedure as residual stones and recurrent stone formation is common.

Abstract
A virological survey for avian influenza (AI) and Newcastle disease (ND) was conducted in two selected live bird markets (LBMs), namely Kaptan Bazar and Karwan Bazar in Dhaka city, Bangladesh from August 2011 to July 2012. A total of 513 dead chickens were collected. An immune-chromatographic rapid antigen test for Type A influenza virus and both conventional and real time RT-PCR were used for the detection and characterization of AI and ND viruses. All carcasses were first screened by the rapid antigen test kit and 93 were positive for Type A influenza virus. RT-PCR on a representative number of rapid antigen test positive samples (n = 24) confirmed the presence of Type A influenza virus and mostly H5 influenza virus (22 out of 24 tested samples). Influenza rapid test negative samples (n = 420) were subjected to routine necropsy. Heat stress, suffocation and physical injury were the most common cause of mortality (163 cases), followed by ND, suspected to be the cause of 85 deaths. On molecular investigation of these 85 samples, the presence of ND virus was confirmed in 59 and AI virus in 6; 15 were negative for both ND and AI viruses and 5 were unsuitable for investigation. Among the 59 ND confirmed cases 18 also contained AI virus. In summary, out of 513 carcasses 117 (22.81%) contained AI virus and 59 (11.50%) contained ND virus. Eighteen (3.51%) carcasses contained both AI and ND viruses. The findings suggest that both AI and ND should be considered as major threats to the poultry industry.Bangl. vet. 2016.

Abstract
OBJECTIVE The goal of this study was to evaluate whether pretransplant serum hyaluronic acid (HA) levels can predict outcomes after adult-to-adult living donor liver transplantation (LDLT). METHODS In study I, 21 patients who underwent LDLT (March 2002-February 2004) were divided into 2 groups: the H-I group (HA ≥500 ng/mL; n = 12) and the L-I group (HA <500 ng/mL; n = 9). The influence of pretransplantation HA levels on short-term surgical outcome was investigated. In study II, 77 LDLT patients (May 2004-December 2014) were also divided into 2 groups: the H-II group (HA ≥500 ng/mL; n = 40) and the L-II group (HA <500 ng/mL; n = 37). We compared long-term survival and investigated prognostic factors. RESULTS In study I, HA levels significantly decreased after LDLT, and those in the H-I group were significantly higher compared with the L-I group at 1, 3, 5, and 7 days after LDLT. There were significant differences in postoperative peak total bilirubin levels (H-I vs L-I, 17.2 vs 6.2 mg/dL; P = .013), peak ascitic fluid volume (1327 vs 697 mL/d; P = .005), and the hepatocyte growth factor levels at 3 days after LDLT (1879 vs 1092 pg/mL; P = .03). In study II, the 1- and 5-year survival rates were significantly lower in the H-II group than in the L-II group (H-II vs L-II, 65.0% and 48.5% vs 86.5% and 80.8%; P = .004). In multivariate analysis, significant prognostic factors were preoperative HA ≥500 ng/mL (P = .004) and graft to recipient body weight ratio <0.8 (P = .042). CONCLUSIONS Preoperative HA level can be a prognostic risk factor. Patients with high HA levels are vulnerable and should be carefully managed after LDLT.

Abstract
Mortality and morbidity was assessed after adoption of a systematic care for patient with pancreatoduodenectomy starting from patient selection and preparation, operative technique, and postoperative care. In this prospective study seventy patients who underwent pancreatoduodenectomy for periampullary carcinoma with curative intent between January 2010 and December 2014 were carefully analyzed prospectively. Patients were selected those who had ampullary carcinoma, lower bile duct carcinoma and small size carcinoma head of pancreas without local invasion and distant metastasis, and the patient who did not have any major disabling comorbid diseases. All patients were assessed uniformly before surgery and deficiency were corrected up to normal level before operation. Pancreatoduodenectomy and standard lymphadenectomy was performed meticulously with minimum blood loss. The pancreatojejunal reconstruction was performed using duct-to-mucosa method mostly. A nasojejunal feeding tube was placed in most patients for starting postoperative early oral feeding. Broad spectrum antibiotics and the epidural analgesia were mostly prescribed for good control infection and pain. Proper nutrition was maintained in calculative way through central venous line and nasojejunal feeding tube in the early postoperative period. General care, early mobilization and chest physiotherapy were given routinely in each patient. Seventy-seven percent (n=54) patients did not have any postoperative complications and they were discharged from hospital within 12-14 postoperative days. The morbidity occurred in 16 patients (23%) and most common complication was wound infection (18%, n=9). The rest complications were pancreatojejunal anastomotic leakage - 2, hepaticojejunal anastomosis leakage - 1, melaena - 1, intra-abdominal abscess - 1, intra-abdominal hemorrhage - 1, and renal dysfunction - 1. The mortality rate was 5.7% (n=4), causes of death were massive myocardial infarction; 1, failure of reversal from anesthesia; 1, massive intraabdominal bleeding; 1 and CV catheter related severe sepsis; 1. Review of recent published literature revealed that mortality and morbidity our series is better than low volume center and almost similar with high volume center of pancreatoduodenectomy surgery. Our systematic management policy of careful patient selection, planned approach in the form of proper work up, meticulous conduction of the procedure, appropriate postoperative care provides an acceptable morbidity and mortality after pancreatoduodenectomy.

Abstract
The role of growth factors in the modulation of ovarian function is an interesting area of research in reproductive biology. Recently, we have shown the expression and role of IGF, EGF, VEGF and FGF in the follicle and CL. Here, we report the presence of Bone Morphogenetic Proteins (BMPs) and their functional receptors in the corpus luteum (CL) of buffalo. The bubaline CL was classified into four stages according to the morphology and progesterone (P4) concentration. The qPCR, immunoblot and immunohistochemistry studies revealed that BMP2 and BMP Receptors (BMPR1A, BMPR1B and BMPR2) were significantly upregulated during the mid stage whereas BMP4 and BMP7 were upregulated during the early stage of CL (P<0.05). Studies on primary luteal cell culture (LCC) using mid CL showed a significant time and concentration dependent effect of BMP4 and BMP7 (P<0.05). At 100ngml-1, the BMPs maximally stimulated the transcripts of StAR, CYP11A1 and 3βHSD that paralleled with P4 accretion in the media (P<0.05). Further, the BMP4 as well as BMP7 upregulated the transcripts of PCNA and downregulated CASPASE3 in the LCC at the same concentration (P<0.05). Though the combined effect of BMP4 and 7 was significantly higher (P<0.05) than that of individual one, it was not additive. In conclusion, the expression of BMPs and their receptors were dependent on the stages of CL in the buffalo. Treatment of LCC with BMPs in vitro confirmed the presence of functional receptors that stimulated the P4 production and luteal cell survival. Moreover, the results support the concept that the upregulation of P4 and its biosynthetic pathway enzymes such as CYP11A1, StAR and 3βHSD in the CL is likely due to the autocrine and /or paracrine effects of BMP4 and BMP7 under physiological milieu.

Abstract
Aim: To determine an efficient vaccination schedule on the basis of the humoral immune response of cell culture adapted live classical swine fever virus (CSFV) vaccinated pigs and maternally derived antibody (MDA) in piglets of vaccinated sows. Materials and Methods: A cell culture adapted live CSFV vaccine was subjected to different vaccination schedule in the present study. Serum samples were collected before vaccination (day 0) and 7, 14, 28, 42, 56, 180, 194, 208, 270, 284 and 298 days after vaccination and were analyzed by liquid phase blocking enzyme-linked immunosorbent assay. Moreover, MDA titre was detected in the serum of piglets at 21 and 42 days of age after farrowing of the vaccinated sows. Results: On 28 days after vaccination, serum samples of 83.33% vaccinated pigs showed the desirable level of antibody titer (log10 1.50 at 1:32 dilution), whereas 100% animals showed log10 1.50 at 1:32 dilution after 42 days of vaccination. Animals received a booster dose at 28 and 180 days post vaccination showed stable high-level antibody titre till the end of the study period. Further, piglets born from pigs vaccinated 1 month after conception showed the desirable level of MDA up to 42 days of age. Conclusion: CSF causes major losses in pig industry. Lapinised vaccines against CSFV are used routinely in endemic countries. In the present study, a cell culture adapted live attenuated vaccine has been evaluated. Based on the level of humoral immune response of vaccinated pigs and MDA titer in piglets born from immunized sows, it may be concluded that the more effective vaccination schedule for prevention of CSF is primary vaccination at 2 months of age followed by booster vaccination at 28 and 180 days post primary vaccination and at 1 month of gestation.

Abstract
This prospective study was designed to evaluate whether early changes in actin-free Gc-globulin levels were associated with complications and outcomes and to identify factors associated with persistent low actin-free Gc-globulin levels in acute liver failure (ALF). Thirty-two consecutive ALF patients admitted from October 2011 to December 2012 were followed up until death or complete recovery. All had serum actin-free Gc-globulin estimation at admission and at day three or expiry. Logistic regression analysis was performed to identify independent predictors of mortality. A receiver operating characteristic curve analysis was also performed. Nonsurvivors had significantly lower median actin-free Gc-globulin levels than survivors (87.32 vs 180 mg/L; P < 0.001). A receiver operating characteristic curve analysis revealed an area under curve (AUC) of 0.771 and showed that serum actin-free Gc-globulin level of ≤124 mg/L would predict mortality with 92% sensitivity and 71.4% specificity. Patients with lower serum actin-free Gc-globulin levels and decreasing trend in serum actin-free Gc-globulin levels were found to have more mortality and developed more complications. Logistic regression analysis showed that serum actin-free Gc-globulin, total leucocyte count and serum creatinine at admission were independent predictors of mortality. Incorporating these variables, a score predicting mortality risk at admission was derived. The scoring system was compared to MELD score and King's College Criteria as individual predictor of mortality. Serum actin-free Gc-globulin level at presentation is predictive of outcome and can be used for risk stratification. Its persistent low-level predicts mortality and is correlated with various complications.

Abstract
Foot-and-mouth disease virus (FMDV) serotypes O, A and Asia1 are responsible for significant number of disease outbreaks in Bangladesh; however serotype Asia1 has not been reported in circulation since 1996. The present investigation reports the detection of serotype FMDV Asia1 from local farms in 2012 and 2013 outbreaks. The farms were located in Jessore and Gazipur districts, and one of these farms was under vaccine control programme. Phylogenetic analysis of the complete VP1 gene revealed that FMDV Asia1 is under genetic lineage C having close similarity to the Asia1 sequences of Indian origin. The circulatory genotype Asia1 showed VP1 protein sequence heterogeneity of eight amino acid substitutions within the G-H loop with the vaccine strain [IND 63/72 (AY304994)] used in vaccination programme. ELISA assay revealed that, of seven, only one local field serum sample (cattle vaccinated 38 days earlier) was positive at a titre level of >2.4 (log10) but failed to protect the cattle from infection occurred by the virus. This investigation focused that the eight amino acid substitution in VP1 protein at G-H loop of the locally circulated FMDV serotype Asia1 strain may be a reason for current vaccination failure.

Abstract
An observational cross-sectional study of 50 cases of chronic calcific pancreatitis patients was conducted in Bangabandhu Sheikh Mujib Medical University (BSMMU) and some other tertiary level hospitals of Dhaka city from August 2008 to July 2010. Patients required laparotomy for different modalities of surgical treatment to manage chronic calcific pancreatitis were included in the study. Biopsy was taken from panceatic duct containing stone during laparotomy to determine the histopathological changes. Among 50 cases female predominance was observed. Male, female ratio was 2:3. Majority (62%) patients were in 20 to 40 years age group. Female presented earlier than male (20-30 years and 30-40 years respectively). All patients complained recurrent attack of epigastric pain. Other presentations were diabetes (74%), malnutrition and weight loss (56%), steatorrhoea (24%) and jaundice (12%). Adenocarcinoma was found in 3(6%) patients (2 male and 1 female) and rests were chronic pancreatitis. Several studies showed the association between chronic calcific pancreatitis and pancreatic cancer. Further large scale study is required to find out the national incidence level.

Abstract
Introduction Atherosclerotic cardiovascular disease is a significant modifiable complication in patients with diabetes and subclinical atherosclerosis is considered a surrogate marker of future vascular events. The clustering of cardiometabolic-risk factors in patients with diabetes and cardiovascular disease is increasingly being recognised. Recent evidence indicates that 20–50% of asymptomatic patients with diabetes may have silent coronary heart disease. However, the identification of subclinical atherosclerosis and silent myocardial ischaemia in patients with diabetes has been less well-explored, especially in low-resource population settings where cost-effective non-invasive clinical tools are available. The objective of this study is to identify patients with physician-diagnosed diabetes who are at risk of developing future cardiovascular events measured as subclinical atherosclerosis and silent myocardial ischaemia in an urban population of Eastern India. Methods and analysis This is a cross-sectional clinico-observational study. A convenience sampling of approximately 350 consecutive patients with type 2 diabetes based on predefined inclusion and exclusion criteria will be identified at an urban diabetes center. This estimated sample size is based on an expected prevalence of silent myocardial ischaemia of 25% (± 5%), we computed the required sample size using OpenEpi online software assuming an α level of 0.05 (95% CI) to be 289. On factoring 20% non-response the estimated sample size is 350. Previously validated questionnaire tools and well-defined clinical, anthropometric and biochemical measurements will be utilised for data collection. The two primary outcomes—subclinical atherosclerosis and silent myocardial ischaemia will be measured using carotid intima-media thickness and exercise tolerance testing, respectively. Descriptive and multivariate logistic regression statistical techniques will be employed to identify ‘at risk’ patients with diabetes, and adjusted for potential confounders. Ethics and dissemination Ethical approval was granted by the institutional review board of Kalinga Institute of Medical Sciences, Bhubaneshwar, India. Data will be presented at academic fora and published in peer-reviewed journals.

Abstract
This study was undertaken to assess the efficacy of delayed primary closure in prevention of postoperative wound infection in patients with obstructive jaundice and septic abdomen. Here analyzed 93 patients retrospectively who underwent surgery in hepato-biliary-pancreatic unit of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from January 2011 to June 2011. Primary closure of the abdominal wound was applied in all patients. There was no mortality, but 21 patients had postoperative morbidity (wound infection in 17, intra-abdominal abscess in 1, melaena in 1, biliary leakage in 1, burst abdomen in 1). Seventy-two patients had uneventful postoperative recovery were included in Group 1. Patients who developed postoperative wound infection (n=17) were included in Group 2. Rest 4 patients who developed other complications were excluded from the study. Pre-, per and postoperative parameters were compared between two groups for identifying the risk factors for SSI. Delayed primary closure of the wound was applied prospectively in 21 patients (Group 3) on the basis of retrospective results and the outcome was assessed. Retrospective analysis revealed that the patient who developed wound infections (Group 2) after primary closure; significantly greater number of patients had obstructive jaundice or intra-abdominal septic condition preoperatively. Prospective results revealed that there was no wound infection in 21 patients with in obstructive jaundice or intra-abdominal sepsis in which delayed primary closure was applied. Hospital stay was significantly reduced in Group 3 in compare to Group 2. In subsequent follow up, it has been found that 2 patients developed incisional hernia in Group 2 patients but none in Group 3 patients. Delayed primary closure of the wound is a good option in patient with obstructive jaundice and intra-abdominal septic condition for preventing postoperative wound infection.

Abstract
This study was designed to observe the effect of cytochalasin B (CCB) concentrations on ploidy and early development of parthenogenetic embryos in a caprine species. Caprine oocytes were matured in the presence of different concentrations of CCB (5, 10, 15, and 20 μg/ml) and activated by 7% ethanol followed by incubation with 2 mM DMAP. For embryos fertilized in vitro, oocytes were matured in maturation medium without CCB. The cleavage rate and further embryo development were significantly higher (P < 0.05) when oocytes were treated in this way. The percentage of embryos showed higher diploid values in 15 μg/ml CCB (83.66 ± 1.13), followed by 20 (72.22 ± 1.22), 10 (68.57 ± 1.17), and 5 μg/ml (62.00 ± 2.48). These results indicate that CCB with a concentration of 15 μg/ml in maturation medium can be used for the production of diploid parthenogenetic embryos in the caprine species.

Abstract
Mesenchymal stromal cells (MSC) are multipotent cells that can be derived from many different organs and tissues. While there are many ways to label and track cells each with strengths and weakness, the green fluorescent protein (GFP) is a reporter gene commonly employed. In the present study, caprine MSC were collected from bone marrow and cells were characterised with MSC specific markers. Passage 10 (P10) MSC cells were transfected using plasmid vector containing GFP as reporter gene with different concentrations of DNA and lipofectamine. Six different concentrations of DNA and lipofectamine as 1 microg DNA: 2 microL lipofectamine, 1 microg DNA: 2.5 microL lipofectamine, 1.2 microg DNA: 2.2 microL lipofectamine, 1.2 microg DNA: 2.5 microL lipofectamine, 1.5 microg DNA: 2.5 microL lipofectamine, 1.5 microg DNA: 3 microL lipofectamine were used. After 24 h and 48 h of transfection, caprine MSC were observed under florescent microscope. Highest transfection rate indicating green flourecscent MSC were found when the cells were transfected with 1.2 microg DNA: 2.2 microL lipofectamine and 1.5 microg DNA: 2.5 microL lipofectamine than other combinations. These cells have been propagated beyond 4th passage maintaining GFP expression. The results indicated that stable GFP positive MSC cells can be generated using the above protocol. These cells are being used for transplantation studies.

Abstract
This study was undertaken to find out reasons of delayed referral for surgical treatment and to assess the effect of delayed referral on management and prognosis of patients with periampullary carcinoma. Patients with histopathologically proved periampullary carcinoma (n=41) during the period January 2010 to December 2010 who had been admitted into the department of surgery, Bangabandhu Sheikh Mujib Medical University, Shahbagh, Dhaka, Bangladesh (BSMMU) were included in this study. Information of the patient was retrieved from medical records. Patients and relatives were interviewed for reasons of delay in seeking surgical help. Patients were divided into two groups: Group I: those who admitted to surgical unit within one month (6 days to 1 month) of noticing jaundice (n=13), and Group II: those who admitted to surgical unit after one month (1.2 months to 18 months) of noticing jaundice (n=28). Parameters were compared between two groups. Patients in group II were poor liver function and nutritional status needed more supplementary therapy in perioperative period. The incidence of distant metastasis and ascites were more frequent in Group II than Group I patients. Definitive procedure (Whipple's operation) was possible in 53.8% patients in Group I whereas only 7.1% in Group II patients (p <0.05). The reasons for delay referral to surgery were due to patient's ignorance, superstition and fear of receiving operative treatment. Delay in diagnosis of periampullary carcinoma as a cause of jaundice and immediate relief of jaundice with ERCP and stenting is another important cause of delay in seeking definitive operative treatment. Awareness of public as well as general physicians is required for early referral of patients with periampullary carcinoma to surgery. Joint assessment of these patients by Gastroenterologist and Hepatobiliary surgeons before internal biliary drainage will improve prognosis.

Abstract
BACKGROUND South Asians show an elevated cardiometabolic risk compared to Caucasians. They are clinically metabolically obese but are considered normal weight based on current international cut-off levels of several anthropometric indices. This study has two main objectives: (i) to predict the most sensitive anthropometric measures for commonly studied cardiometabolic risk factors, and (ii) to determine optimal cut-off levels of each of the anthropometric indices in relation to these cardiometabolic risk factors in South Asians. METHODS The study was conducted on a random sample of 1178 adults of 20-80 years of age from an urban population of eastern India. Obesity, as evaluated by standard anthropometric indices of BMI (body mass index), WC (waist circumference), WHpR (waist-to-hip ratio) and WHtR (waist-to-height ratio), was individually correlated with cardiometabolic risk factors. Receiver operating characteristic (ROC) curve analyses were performed which includes: (i) the area under the receiver operating characteristic curve (AUROC) analysis to assess the predictive validity of each cardiometabolic risk factor; and (ii) Youden index to determine optimal cut-off levels of each of the anthropometric indices. RESULTS Overall, AUROC values for WHtR were the highest, but showed variations within the sexes for each of the cardiometabolic risk factors studied. Further, WHpR cut-offs were higher for men (0.93-0.95) than women (0.85-0.88). WC cut-offs were 84.5-89.5 cm in men and 77.5-82.0 cm in women. For both sexes the optimal WHtR cut-off value was 0.51-0.55. The optimal BMI cut-offs were 23.4-24.2 kg/m2 in men and 23.6-25.3 kg/m2 in women. CONCLUSION WHtR may be a better anthropometric marker of cardiometabolic risks in South Asian adults than BMI, WC or WHpR.

Abstract
BACKGROUND AND OBJECTIVES Although ES cells have been derived from very early stage embryos in different species, but, so far ES cell line could be derived from early stage IVF embryos in buffalo. The present experiment was carried out to study the effects of different growth factors on attachment, formation of ES cell colonies, their extent of passaging and relative expression of pluripotency marker in these colonies in buffalo. METHODS AND RESULTS For this, 8~16 cell stages zona free IVF embryos were cultured with different culture condition viz. Control, Media-I: (Control+SCF), Media-II: (Control+SCF+bFGF) and Media-III: (Control+SCF+bFGF+IGF1). A total of 25 number of embryos were cultured in each medium. The efficiency (%) of blastomere attachment, % stem cell colony formation were recorded and number of passaging were evaluated in each culture condition. The results indicated that the efficiency of embryonic blastomere attachment, % stem cell colonies formation and propagation were significantly higher when medium was supplemented with growth factors viz. SCF, bFGF and IGF-1 (Media-III) than when supplemented with either SCF or SCF+bFGF. The expression of pluripotent genes viz Oct4, Nanog, FoxD3 and KLF4 were significantly higher (p<0.005) when medium was supplemented with three growth factors. CONCLUSIONS It can be concluded that when 8~16 cell stages zona free IVF embryos of buffalo was cultured on feeder,the %of blastomere attachment, % of ES cell colony formation and their further propagation were higher in ES cell medium supplemented with SCF+bFGF+IGF1 which may be due to high expression of pluripotent stem cell markers.

Abstract
OBJECTIVES To determine the prevalence of metabolic syndrome and to identify predictors for the same, specific to an underdeveloped urban locale of Eastern India. MATERIALS AND METHODS STUDY DESIGN Population-based cross-sectional study, with multistage random sampling technique. SETTING Urban city-dwellers in Orissa one of the poorest states of Eastern India bordering a prosperous state of Andhra Pradesh of Southern India. PARTICIPANTS 1178 adults of age 20-80 years randomly selected from 37 electoral wards of the urban city. Definition of Metabolic Syndrome: We followed a unified definition of the metabolic syndrome by joint interim statement of five major scientific organizations - the International Diabetes Federation, the National Heart, Lung, and Blood Institute, the American Heart Association, the World Heart Federation, the International Atherosclerosis Society, and the International Association of the Study of Obesity. Individuals who meet at least three of five clinical criteria of abdominal obesity, hypertriglyceredimia, low HDL, hypertension, and hyperglycemia are diagnosed as having the condition; presence of none of these criteria is mandatory. Explicit cut points are defined for all criteria, except elevated waist circumference, which must rely on population and country-specific definitions. MAIN OUTCOME MEASURE Prevalence and significant predictors of metabolic syndrome. STATISTICAL ANALYSIS Both descriptive and multivariable logistic regression analyses. RESULTS Age-standardized prevalence rates of metabolic syndrome were 33.5% overall, 24.9 % in males and 42.3% in females. Older age, female gender, general obesity, inadequate fruit intake, hypercholesterolemia, and middle-to-high socioeconomic status significantly contributed to increased risk of metabolic syndrome. CONCLUSION Metabolic syndrome is a significant public health problem even in one of the poorest states of India that needs to be tackled with proven strategies.

Abstract
Evidence is emerging that obesity-associated cardiovascular disorders (CVD) show variations across regions and ethnicities. However, it is unclear if there are distinctive patterns of abdominal obesity contributing to an increased CVD risk in South Asians. Also, potential underlying mechanistic pathways of such unique patterns are not comprehensively reported in South Asians. This review sets out to examine both. A comprehensive database search strategy was undertaken, namely, PubMed, Embase and Cochrane Library, applying specific search terms for potentially relevant published literature in English language. Grey literature, including scientific meeting abstracts, expert consultations, text books and government/non-government publications were also retrieved. South Asians have 3-5% higher body fat than whites, at any given body mass index. Additional distinctive features, such as South Asian phenotype, low adipokine production, lower lean body mass, ethno-specific socio-cultural and economic factors, were considered as potential contributors to an early age-onset of obesity-linked CVD risk in South Asians. Proven cost-effective anti-obesity strategies, including the development of ethno-specific clinical risk assessment tools, should be adopted early in the life-course to prevent premature CVD deaths and morbidity in South Asians.

Abstract
The causal associations between cigarette smoking and human diseases are irrefutable. In this review, we focus on the epidemiological pattern of cigarette smoking on cardiovascular risk, the underlying mechanistic process of such a causal link, how to prevent premature cardiovascular morbidity and mortality particularly through smoking cessation, and the health benefits of such cessation measures. Finally, we conclude our review summarizing a few of the proven evidence-based tobacco control strategies and policies from across the globe. We did not conduct a systematic review but followed a similar structure. We abstracted the most relevant published literature on the electronic databases, namely, PubMed, Embase and the Cochrane Library applying specific search terms. We also searched gray literature and consulted experts in the field for cross-references. Smoking has been estimated to cause about 11% of all deaths due to cardiovascular disease. Smoking contributes to the pathogenesis of coronary artery disease and sudden death through a variety of mechanisms, including the promotion of atherosclerosis, the triggering of coronary thrombosis, coronary artery spasm, and cardiac arrhythmias, and through reduced capacity of the blood to deliver oxygen. Smoking cessation also confers substantial benefits on people with serious heart disease. Smoking cessation should be viewed as therapeutic rather than preventive intervention, similar to treating asymptomatic hypertension. Smoking cessation is highly cost-effective relative to other frequently used medical and surgical interventions. Tobacco related illnesses are important public health issues worldwide. It has been estimated that there are 1.1 billion smokers worldwide and 250 million of them live in India.

Abstract
This study was designed to determine the prevalence, forms of transmission, mutational profile and viral load at baseline of hepatitis B virus (HBV) carriers in Delhi. HBV surface antigen (HBsAg)-positive patients were enrolled and evaluated clinically for liver function, serological markers for hepatitis B and HBV DNA quantitation. Tests were carried out again 1 year later and the results were compared. Liver biopsy was carried out on all carriers with active viral replication. HBV DNA-positive samples were subjected to polymerase chain reaction single-stranded conformation polymorphism (PCR-SSCP) to screen mutations in the Precore, core, and the X-gene prior to sequencing analysis. Among the 100 patients examined, HBeAg was detected in 23% and 40% were HBV DNA-positive. Of the 40 HBV DNA-positive cases, 8 had precore/core mutations, [G1896A (10%), T2066A (12.5%), T2050C (10%), and G1888A (7.5%)]. No X gene mutants were detected. Reduction in viral load was higher in HBeAg-positive patients, as compared to HBeAg-negative patients, over 1 year. At follow-up, 2/8 HBV mutants corresponded with altered liver function and morphological changes suggestive of chronic hepatitis. One patient was re-designated as DNA-negative on follow-up and had wild-type virus infection with a relatively low viral load. The predominant route for HBV transmission was determined to be parenteral. Twenty percent of the HBV carriers were infected with precore and core mutant HBV. Although the clinical and biochemical profiles of these HBV carriers remained largely stable on follow-up, there was evidence of spontaneous reduction in the mean viral load over the 1-year study period.

Abstract
Assessment of total plasma DNA can be a promising noninvasive tool for monitoring the effect of cytotoxic therapies in order to predict therapeutic efficacy at an early stage. Cell-free plasma DNA levels were quantified before the first, second and third cycle of chemotherapy in 42 patients with advanced nonsmall cell lung cancer and correlated with response to therapy, as assessed by computed tomography following the third chemotherapy cycle. A significantly lower plasma DNA level, measured before various treatment cycles, was found in patients with remission or stable disease than in those with progression. Higher levels and insufficient decrease in plasma DNA levels during the course of chemotherapy indicated poor outcome. For predicting insufficient therapy response, a sensitivity of 26.9% was achieved at 100% specificity using plasma DNA levels before the first therapy cycle. Prediction of disease progression was achieved with a sensitivity of 35.7% at 100% specificity using plasma DNA levels before the first therapy cycle. Monitoring of plasma DNA levels during the course of chemotherapy could identify patients who are likely to exhibit an insufficient therapeutic response and disease progression at an early stage. This may help in individualising treatment, and could lead to better management of advanced-stage lung cancer.

Abstract
Evidence regarding health benefits of physical activity is overwhelming and plays a critical role in both the primary and secondary prevention of coronary artery disease (CAD). Epidemiological investigations show approximately half the incidence of CAD in active compared to sedentary persons. A sedentary lifestyle is considered by various national and international organizations to be one of the most important modifiable risk factors for cardiovascular morbidity and mortality. Fortunately, a moderate level of occupational or recreational activity appears to confer a significant protective effect. Once coronary artery disease has become manifest, exercise training can clearly improve the functional capacity of patients and reduce overall mortality by decreasing the risk of sudden death. Well-designed clinical investigations, supported by basic animal studies, have demonstrated that the beneficial effects of exercise are related to direct and indirect protective mechanisms. These benefits may result from an improvement in cardiovascular risk factors, enhanced fibrinolysis, improved endothelial function, decreased sympathetic tone, and other as-yet-undetermined factors. Hence physical fitness, more than the absence of ponderosity or other factors, is the major determinant of cardiovascular and metabolic risk and long-term disease-free survival, in effect linking health span to life span. It is obviously in every individual's interest to assume the responsibility for his or her own health and embrace this extremely effective, safe, and inexpensive treatment modality. The need for a comprehensive review of this particular topic has arisen in view of the high prevalence of physical inactivity and overwhelming evidence regarding CVD risk reduction with regular physical activity.

Abstract
e22213 Background: Recently, breast cancer has become the most common cancer among women in all urban population in India. Annually about 80000 new cases and 40000 deaths occur and majority of breast cancers are pre-menopausal. Conventional diagnostic methods are not very sensitive especially in early stages of cancer. This necessitated a more sensitive and reliable method for early diagnosis leading to effective treatment, better prognosis and survival. Recently, the level of cell free circulating tumor DNA in blood plasma or serum of patients with variety of tumors are being considered as reliable non-invasive diagnostic tool but no study has been done in India. The present study has therefore been undertaken to evaluate clinical utility of cell free DNA as potential biomarkers for early diagnosis and management of breast cancer. Methods: 25 newly diagnosed untreated breast cancer patients and 25 healthy subjects having no sign of significant medical illness with informed consent were enrolled for the study. 9 patients after chemotherapy were also included in the study. Blood plasma collected from both patients and controls were employed for DNA isolation, using Qiagen kit. Concentration of cell free plasma DNA was analyzed by 3 methods viz. nanodrop spectro-photometry, integrated density value (IDV) of PCR products of Exon 7 of p53 gene and quantitative real time PCR (cycles threshold converted to genome equivalent). All values of DNA concentration obtained by three methods used as continuous variables and receiver operating characteristic (ROC) were plotted and the cut-of value was determined at 90% sensitivity and 100% specificity level of ROC. Results: Mean free plasma DNA concentration as determined by both Q-RT PCR and IDV in cancer patients was found to be significantly higher in advanced stage breast cancer patients than in controls (genome equivalent 18850 vs 431; IDV 17912 vs 4197; p=0.001). However, no significant difference could be observed in early stage disease as compared to controls possibly due small sample size. Conclusions: Free Plasma DNA concentration is a reliable molecular marker for detection of breast cancer and can serve as a prognostic indicator leading to its potential clinical application either alone or in combination with other conventional methods. No significant financial relationships to disclose.

Abstract
The constitutively activated STAT family members, particularly STAT3, have been shown to possess transforming properties, and are strongly correlated with tumor development and progression. STAT3 transmits signals from many cytokines and growth factors to target genes in the nucleus through the Jak/Stat signaling pathway. HPV is the main etiological factor in the development of cervical cancer. In the current study, the expression of STAT3 was analyzed in various stages of HPV-mediated cervical carcinogenesis. Tissue biopsies from 100 patients with cervical cancer of different stages and normal tissues from patients undergoing hysterectomy were selected for studying the HPV status and STAT3 expression. HPV status of each corresponding biopsy was analyzed by PCR and typing. The mRNA expression was analyzed by reverse-transcriptase polymerase chain reaction (RT-PCR). HPV infection was detected in majority of cases: 75% (9/12) in precancer, 85% (34/40) stage I & II, and 95% (36/38) in stage III & IV of cervical cancer cases by L1 PCR. Further sub typing revealed HPV16 in 100% (9/9) of L1 positives in precancerous & 90% (63/70) in different stages of cancer. Significant level of STAT3 mRNA expression was predominantly found in cervical cancer cases as compared to normal controls (P = 0.001). We also found a significant correlation of STAT3 expression in cases infected with HPV (P = 0.001). Our results indicate a potentially interactive effect between HPV 16/18 and transcriptional activation of STAT3 gene in cervical carcinogenesis. To our knowledge, this is the first such study to be reported from India. Further investigations are needed to determine the influence of STAT3 expression on cervical carcinogenesis and its possible interaction with HPV infection status.

Abstract
Kangri cancer is a unique, thermally induced squamous cell carcinoma (SCC) of the skin that develops due to persistent use of a Kangri (a brazier) by the Kashmiri people to combat the cold temperature during winter. Unlike classical UV-induced SCC of the skin, Kangri cancer appears on the legs and abdomen. Its common features are erythematous patches, recurrence and metastasis. In the absence of any molecular etiology, we made a preliminary attempt to estimate the nature and frequency of mutations in the TP53 and PTEN genes in Kangri cancer patients from Kashmir. PCR-SSCP analysis followed by direct sequencing revealed that TP53 mutations account for 40% (12/30) of sporadic Kangri cancer patients and that PTEN mutations account for only 6.6% (2/30). There were 16 mutations in TP53 exons 5 and 7, found in 12 patients. They consisted of 11 substitutions (7 transitions, 3 transversions and 1 double-base) and 5 insertions. The 11 substitutions represent 8 distinct missense mutations, 3 of which were silent mutations. The mutations detected in the PTEN gene consisted of one insertion and one C>T transition. This high percentage of TP53 mutations (especially A>G) showed a statistically significant association with age and positive lymph node status. Our results indicate that TP53 is a predominant target of chronic hyperthermia in the development of Kangri cancer in the moderate risk Kashmiri population. The differences in the TP53 mutation spectrum of UV-induced SCC of the skin and Kangri cancer are probably due to the nature of the respective environmental carcinogens. The study also suggests that TP53 may function as a potential molecular marker and prognostic tool, at least in a subset of sporadic Kangri tumors.

Abstract
BACKGROUND & OBJECTIVE Mycoplasma pneumoniae is known to be a major cause of lower respiratory tract infections in children. A specific diagnosis is important to institute the appropriate treatment. Information on diagnostic methods used for M. pneumoniae in Indian paediatric population is scarce. The study was thus conducted to compare polymerase chain reaction (PCR), culture and serology for the diagnosis of M. pneumoniae in community-acquired lower respiratory tract infections in children. METHODS Seventy five children aged 6 months to 12 yr with signs of community-acquired lower respiratory tract infections were selected for the study. Culture of nasopharyngeal aspirates was done. The serum samples were analyzed for the detection of IgM and IgG antibodies to M. pneumoniae. A 543 base pairs (bp) region of P1 gene of M. pneumoniae was selected for amplification in PCR assay applied to nasopharyngeal aspirates. RESULTS M. pneumoniae was isolated in culture from 4 (5.33%) children. Serological evidence of M. pneumoniae infection was observed in 16(21.3%) children. All culture positive patients were also positive by serology. Overall, PCR for M. pneumoniae was positive in 13 (17.3%) patients. All four culture positive patients were also positive by PCR. In 11 out of 13 (84.62%) PCR positive patients, serological evidence was there. Culture and/or serology and/or PCR positive results diagnosed M. pneumoniae infection in 18 (24%) of 75 patients. INTERPRETATION & CONCLUSION A combination of culture, serology and PCR may provide diagnostic information on the aetiology of M. pneumoniae community-acquired lower respiratory tract infections in paediatric population.

Abstract
OBJECTIVE To assess the status of iodine deficiency in the population of Orissa and track progress of the elimination efforts. METHODS A community based field survey was conducted. Data was collected using quantitative and qualitative research methods. Standard internationally recommended protocol and methodology was followed. Thirty clusters were selected using population proportionate to size sampling technique. School children aged 6 to 12 years were selected as target group. Goiter prevalence, urinary iodine excretion in the target group and iodine content of the salt at household were used as outcome variables. RESULTS A total of 1200 children were studied. The total goiter rate was found to be 8.0%, of which 7.6% were grade I and 0.4% was grade-II goiter. The median urinary iodine excretion was found to be 85.4 microg/L and 32.2% of the subjects had urinary iodine levels less than 50 microg/L. Estimation of iodine content by titration method revealed that in only 45% of households salt was found to be adequately iodised. (Salt with iodine level 15 ppm). CONCLUSION Iodine deficiency continues to be a public health problem in Orissa and the need to accelerate efforts to iodine sufficiency cannot be overemphasized.

Abstract
As an alternative to radioimmunoassays, a simple, highly sensitive and quick enzymeimmunoassay (EIA) for determination of cortisol in blood plasma of yaks on microtiterplates using second antibody coating technique and cortisol-horseradish peroxidase as a label has been developed. The wells of the microtiterplate were coated with affinity-purified goat IgG (antirabbit IgG) that binds the hormone specific antibody. The EIA was carried out directly in 20 microl of heat treated plasma after 1:5 dilution with PBS. The cortisol standard curve, with doses ranged from 0.4 to 100 pg/well. The sensitivity of the assay was 20 pg/ml. Cortisol standard curve in buffer showed parallelism with serially diluted yak plasma containing high endogenous cortisol. Intra- and inter-assay coefficients of variation (CV) determined using pooled plasma was found 6.58 and 11.35%, respectively. Recovery of known concentrations of added cortisol in charcoal stripped plasma was linear (r = 0.98). For biological validation of cortisol enzymeimmunoassay, the blood samples were collected from yak cows at -48 and -24h before and 0, 12, 24, 36, 48, 60, 72, 84 and 96 h after dexamethasone administration. The plasma cortisol before dexamethasone administration was significantly (P < 0.05) higher than after dexamethasone administration. The developed EIA was further validated biologically by estimating cortisol in peri-parturient cows beginning day 10 prior to calving till day 10 post-calving; the concentrations were along with the expected lines as reported in bovine. In conclusion, the EIA developed in this study is simple, highly sensitive, valid and sufficiently reliable method for estimation of cortisol directly in bovine plasma.

Abstract
BACKGROUND Investigation of the potential association of single nucleotide polymorphisms (SNPs) at -308 G/A and -238 G/A of Tumor necrosis factor alpha (TNFalpha) with susceptibility to HPV-16 associated cervical cancer in Indian women. METHODS The study included 165 histologically confirmed cases with 45 precancer and 120 cancer patients and an equal number (165) of healthy controls with normal cervical cytology. PCR-RFLP was employed to analyze TNFalpha promoter polymorphisms, which were confirmed by direct sequencing. Both patients and controls were screened for Human Papillomavirus (HPV) infection. RESULTS The frequency of -308 A allele in TNFalpha was significantly higher in cases compared with control subjects (21% in cases vs. 9% in controls; p<0.01), with an odds ratio of 2.7 (95% CI = 1.41-5.15). Also, women carrying A allele for this locus presented 3 times increased susceptibility to HPV 16 infection as evident from carrier genotype distribution between HPV positive cases and control subjects (24% in HPV positive cases vs. 9% in controls; p<0.01; OR = 3.1; 95% CI = 1.60-6.03). No such association was found for TNFalpha-238 (G/A) polymorphism with the risk of development of cervical cancer. CONCLUSION It suggests that SNP at -308 (G/A) of TNFalpha promoter may represent an increased risk for HPV infection and development of cervical cancer in Indian women.

Abstract
BACKGROUND & OBJECTIVE Association of hepatitis G virus (HGV) with acute viral hepatitis (AVH) and fulminant hepatitis (FH) is not clearly understood. This study was designed to asses the occurrence of HGV infection and its relationship with other hepatotropic viruses in patients with FH and AVH and also to determine the nucleotide sequence of HGV isolates. METHODS The study included 100 patients of FH and 125 of AVH on the basis of clinical examination, liver function test and serology for hepatitis A, B, C and E virus. HGV RNA was detected by reverse transcriptase-polymerase chain reaction (RT-PCR) and direct sequencing for 4 randomly selected samples followed by phylogenetic analysis. RESULTS Of the 100 patients with FH, 30 were negative for hepatitis viruses A, B, C and E by serology (non A-non E) while 60 were negative in the AVH group. In the non A-non-E hepatitis group, HGV was positive in 16.66 per cent (5/30) cases of FH, 10 per cent (6/60) cases of AVH and 6 per cent (6/100) of healthy controls. The difference in HGV seropositivity between FH and AVH patients was statistically not significant compared to healthy controls, while HBV and HCV infections were significant. The four isolates sequenced seemed to be of same type and close to Chinese strain of HGV (Y13755.1 Y13756.1 Y15407, and U67782) on phylogeny. INTERPRETATION & CONCLUSION In HGV infection was not found to be clinically significant as well as nonpathogenic in the patients of FH and AVH and appeared to be an innocent bystander in the course of the disease. The four sequenced HGV isolates showed close pairing with Chinese strains.

Abstract
Telomerase is a ribonucleoprotein comprising an RNA template, the telomerase-associated protein and its catalytic subunit, human telomerase reverse transcriptase (hTERT). Telomerase activation is a critical step in cellular immortalisation and development of cancer. Enhanced telomerase activity has been demonstrated in cervical cancer. In the present study telomerase activity and hTERT mRNA expression were evaluated and correlated with the presence of human papillomavirus (HPV) infection and cytological changes in the cervical lesions. Telomerase activity was assayed by telomeric repeat amplification protocol, hTERT mRNA expression by reverse transcriptase polymerase chain reaction and presence of high risk HPV (HR-HPV) infection by polymerase chain reaction. Out of 154 cervical samples of different cytology, 90 (58.44%) were positive for HR-HPV types 16/18, while among 55 normal cervical scrapes, 10 (18.18%) were HPV DNA positive. All 59 invasive cancer samples showed a very high telomerase activity. Among dysplasia, seven (63.6%) mild dysplasia, 18 (100%) of moderate, 20 (100%) of severe dysplasia and 6 (100%) carcinoma in situ (CIS) samples were positive with mild to moderate to high to very high telomerase activity respectively. Seven (12.7%) samples of apparently normal cervical scrapes were weakly positive for telomerase activity. We observed a good correlation (P<0.001) between telomerase activity and HR-HPV 16/18 positivity with a sensitivity of 88.1% for HPV and 100% for telomerase activity. It is suggested that telomerase activity may be used as an adjunct to cytology and HPV DNA testing in triaging women with cervical lesions.
