Abstract
OBJECTIVE To estimate the costs incurred by patients during the intensive and continuation phases of the current 6-month tuberculosis (TB) regimen in Bangladesh and Tanzania, and thus identify potential benefits to patients of a shorter, 4-month treatment regimen. DESIGN The validated Stop TB patient cost questionnaire was adapted and used in interviews with 190 patients in the continuation phase of treatment with current regimens. RESULTS In both countries, overall patient costs were lower during 2 months of the continuation phase (US$74 in Tanzania and US$56 in Bangladesh) than during the 2 months of the intensive phase of treatment (US$150 and US$111, respectively). However, continuation phase patient costs still represented 89% and 77% of the 2-month average national income in the respective countries. Direct travel costs in some settings were kept low by local delivery system features such as community treatment observation. Lost productivity and costs for supplementary foods remained significant. CONCLUSIONS Although it is not a straightforward exercise to determine the exact magnitude of likely savings, a shorter regimen would reduce out-of-pocket expenses incurred by patients in the most recent 2 months of the continuation phase and allow an earlier return to productive activities.

Abstract
STUDY OBJECTIVE To assess the level of HPV knowledge among low income, minority mothers with a child between the ages of 9-17 y. DESIGN Women who sought care at a university-based clinic and had at least 1 child aged 9 to 17 years were approached. A total of 638 mothers were recruited. Only those who had heard of HPV were included in the correlation analyses (n = 468). MAIN OUTCOME MEASURES HPV knowledge was assessed utilizing a self-administered questionnaire consisting of 20 questions. RESULTS There were differences between those who had heard of HPV and those who had not. More of those who had not heard of HPV were Hispanic (63%), low-income (89%), and did not graduate high school (59%). Of those who had heard of HPV, the majority did not answer 50% of questions correctly. Few knew the vaccine could prevent genital warts (19.7%). Factors independently associated with HPV knowledge included age, personal history of HPV, cervical dysplasia or cervical cancer, acquiring knowledge from ≥ 2 sources, having known someone with HPV or cervical cancer, having seen a brochure on the vaccine, and having seen an advertisement for the vaccine. CONCLUSIONS Knowledge regarding HPV is low among low-income women with children in the target age range for HPV vaccination. Increased awareness should focus on genital warts and other cancers, since this population has virtually no knowledge of other health outcomes related to HPV infection. Educational programs tailored to this population need to be developed to increase vaccination.

Abstract
Dry eye (DE) disease is commonly associated with ocular surface inflammation, an unstable tear film and symptoms of irritation. However, little is known about the role of central neural mechanisms in DE. This study used a model for persistent aqueous tear deficiency, exorbital gland removal, to assess the effects of mustard oil (MO), a transient receptor potential ankyrin (TRPA1) agonist, on eyeblink and eyewipe behavior and Fos-like immunoreactivity (Fos-LI) in the trigeminal brainstem of male rats. Spontaneous tear secretion was reduced by about 50% and spontaneous eyeblinks were increased more than 100% in DE rats compared to sham rats. MO (0.02-0.2%) caused dose-related increases in eyeblink and forelimb eyewipe behavior in DE and sham rats. Exorbital gland removal alone was sufficient to increase Fos-LI at the ventrolateral pole of trigeminal interpolaris/caudalis (Vi/Vc) transition region, but not at more caudal regions of the trigeminal brainstem. Under barbiturate anesthesia ocular surface application of MO (2-20%) produced Fos-LI in the Vi/Vc transition, in the mid-portions of Vc and in the trigeminal caudalis/upper cervical spinal cord (Vc/C1) region that was significantly greater in DE rats than in sham controls. MO caused an increase in Fos-LI ipsilaterally in superficial laminae at the mid-Vc and Vc/C1 regions in a dose-dependent manner. Smaller, but significant, increases in Fos-LI also were seen in the contralateral Vc/C1 region in DE rats. TRPA1 protein levels in trigeminal ganglia from DE rats ipsilateral and contralateral to gland removal were similar. Persistent tear reduction enhanced the behavioral and trigeminal brainstem neural responses to ocular surface stimulation by MO. These results suggested that TRPA1 mechanisms play a significant role in the sensitization of ocular-responsive trigeminal brainstem neurons in this model for tear deficient DE.

Abstract
UNLABELLED Similar to cancer statistics in developed countries, breast cancer is also the leading cause of cancer-related death in the women population of Bangladesh particularly the poor and underprivileged. The objective of this study was to study the socio-demography, tumor patterns and risk factors that affect these women from Dhaka and Bangladesh in general. METHOD This cross-sectional study involved 250 patients who presented to NICRH, Dhaka for treatment. These patients were interviewed, physically examined and vital information were gathered using approved questionnaires. Various personal, social, reproductive and tumor related factors were recorded and analyzed. RESULT The mean age of the study group was 44.7 years, standard deviation (SD) was 9.82 (range: 21-67), 87% have children, 57.2% were postmenopausal, 92% were housewives, 51.4% were illiterate, 62% attended 6 months after initiation of symptoms, 72% of the patients' yearly family income were less than US$1000/year. Almost 100% of the patients gave history of cooking from wooden fire source in the rural areas. In our study group, 79.7 percent women were within the group of BMI 20 kg/m2or more. Locally advanced breast cancer patients (T3 and T4) were 52.6%, axillary lymph node involvement was present in 80% of cases, 61.6 % patient received neoadjuvant chemotherapy. In the elderly group (above 40 years) Estrogen receptor was positive in 53.2% cases, 26.6% were Triple negative breast cancer patients. CONCLUSION Women with poor socio-economic status and have none or low educational level are often victims of late presentation and tend to have a higher stage at diagnosis. Poverty, literacy and assorted risk factors have influenced the outcome of breast cancer cases among Bangladeshi women.

Abstract
Bacteriophage named as SAL-PG (Salmonella bacteriophage), specific to Salmonella pullorum and Salmonella gallinarum was isolated by an enrichment method directly from waste water near to poultry farm. For the isolation of phage 4.5 ml water sample, 0.5 ml of 10X Nutrient Broth and 0.5 ml of log phage bacteria were mixed well and incubated at 37° C for overnight followed by centrifugation at 10,000 rpm for 10 minutes. The presence of bacteriophage was observed by spot test over the bacterial lawn of and plaque assay. The host range of the isolated bacteriophage was determined by spot test using 12 different bacterial isolates. The phages were found to infect Salmonella pullorum, Salmonella gallinarum and Salmonella typhimurium and produced clear plaque on these Salmonella serovars. The bacteriophage was able to survive in wide range of pH between 2 to 9 and resistant at 60° C for 1 hour. More than 50% phages were readily adsorbed to the host bacteria. The restriction enzyme analysis showed that the phage DNA possess restriction site for Taq?I, HindIII and BstYI; but no restriction site for XhoI and BstEII as these two enzymes failed to digest the phage DNA. The characterizations of the bacteriophage would be helpful in establishing a basis for adopting the application of the most effective bacteriophage treatment to control these poultry bacteria.DOI: http://dx.doi.org/10.3329/bjvm.v12i2.21264 Bangl.

Abstract
Severe acute pancreatitis (AP) is characterized by leukocyte infiltration and tissue injury. Herein, we wanted to examine the potential effects of thrombin-derived host defense peptides (TDPs) in severe AP. Pancreatitis was provoked by infusion of taurocholate into the pancreatic duct or by intraperitoneal administration of l-arginine in C57BL/6 mice. Animals were treated with the TDPs GKY20 and GKY25 or a control peptide WFF25 30 min before induction of AP. TDPs reduced blood amylase levels, neutrophil infiltration, hemorrhage, necrosis, and edema formation in the inflamed pancreas. Treatment with TDPs markedly attenuated the taurocholate-induced increase in plasma levels of CXCL2 and interleukin-6. Moreover, administration of TDPs decreased histone 3, histone 4, and myeloperoxidase levels in the pancreas in response to taurocholate challenge. Interestingly, administration of TDPs abolished neutrophil expression of Mac-1 in mice with pancreatitis. In addition, TDPs inhibited CXCL2-induced chemotaxis of isolated neutrophils in vitro. Fluorescent-labeled TDP was found to directly bind to isolated neutrophils. Finally, a beneficial effect of TDPs was confirmed in l-arginine-induced pancreatitis. Our novel results demonstrate that TDPs exert protective effects against pathological inflammation and tissue damage in AP. These findings suggest that TDPs might be useful in the management of patients with severe AP.

Abstract
BACKGROUND Most of the Indian studies on prediction equations for spirometry in adults are several decades old and may have lost their utility as these were carried out with equipment and standardisation protocols that have since changed. Their validity is further questionable as the lung health of the population is likely to have changed over time. OBJECTIVE To develop prediction equations for spirometry in adults of north Indian origin using the 2005 American Thoracic Society/European Respiratory Society (ATS/ERS) recommendations on standardisation. METHODS Normal healthy non-smoker subjects, both males and females, aged 18 years and above underwent spirometry using a non-heated Fleisch Pneumotach spirometer calibrated daily. The dataset was randomly divided into training (70%) and test (30%) sets and the former was used to develop the equations. These were validated on the test data set. Prediction equations were developed separately for males and females for forced vital capacity (FVC), forced expiratory volume in first second (FEV1), FEV1/FVC ratio, and instantaneous expiratory flow rates using multiple linear regression procedure with different transformations of dependent and/or independent variables to achieve the best-fitting models for the data. The equations were compared with the previous ones developed in the same population in the 1960s. RESULTS In all, 685 (489 males, 196 females) subjects performed spirometry that was technically acceptable and repeatable. All the spirometry parameters were significantly higher among males except the FEV1/FVC ratio that was significantly higher in females. Overall, age had a negative relationship with the spirometry parameters while height was positively correlated with each, except for the FEV1/FVC ratio that was related only to age. Weight was included in the models for FVC, forced expiratory flow (FEF75) and FEV1/FVC ratio in males, but its contribution was very small. Standard errors of estimate were provided to enable calculation of the lower limits of normal and standardised residuals for these parameters. The equations were found to be valid on the test dataset, and therefore, may be extended to general population. Comparison with the 1960s equations revealed lack of good agreement, and substantially higher predicted FVC with the current equations, especially in the forty-years-plus age group, in both males and females. Even in the age group upto 40 years, the level of agreement was clinically not acceptable. CONCLUSIONS Validated prediction equations have been developed for spirometry variables in adults of north Indian origin using the current ATS/ERS spirometry standardisation recommendations. The equations suggest an improvement in the lung health of the population over time in the middle-aged and the elderly. These equations should address a long-felt unmet need and enable a more appropriate evaluation of spirometry data in different chest diseases in Indian subjects.

Abstract
Excessive neutrophil activation is a major component in septic lung injury. Neutrophil-derived DNA may form extracellular traps in response to bacterial invasions. The aim of the present study was to investigate the potential role of neutrophil extracellular traps (NETs) in septic lung injury. Male C57BL/6 mice were treated with recombinant human (rh)DNAse (5 mg/kg) after cecal ligation and puncture (CLP). Extracellular DNA was stained by Sytox green, and NET formation was quantified by confocal microscopy and cell-free DNA in plasma, peritoneal cavity, and lung. Blood, peritoneal fluid, and lung tissue were harvested for analysis of neutrophil infiltration, NET levels, tissue injury, as well as CXC chemokine and cytokine formation. We observed that CLP caused increased formation of NETs in plasma, peritoneal cavity, and lung. Administration of rhDNAse not only eliminated NET formation in plasma, peritoneal cavity, and bronchoalveolar space but also reduced lung edema and tissue damage 24 h after CLP induction. Moreover, treatment with rhDNAse decreased CLP-induced formation of CXC chemokines, IL-6, and high-mobility group box 1 (HMGB1) in plasma, as well as CXC chemokines and IL-6 in the lung. In vitro, we found that neutrophil-derived NETs had the capacity to stimulate secretion of CXCL2, TNF-α, and HMGB1 from alveolar macrophages. Taken together, our findings show that NETs regulate pulmonary infiltration of neutrophils and tissue injury via formation of proinflammatory compounds in abdominal sepsis. Thus we conclude that NETs exert a proinflammatory role in septic lung injury.

Abstract
Cornea-evoked eyeblinks maintain tear film integrity on the ocular surface in response to dryness and protect the eye from real or potential damage. Eyelid movement following electrical stimulation has been well studied in humans and animals; however, the central neural pathways that mediate protective eyeblinks following natural nociceptive signals are less certain. The aim of this study was to assess the role of the trigeminal subnucleus interpolaris/caudalis (Vi/Vc) transition and subnucleus caudalis/upper cervical cord (Vc/C1) junction regions on orbicularis oculi electromyographic (OOemg) activity evoked by ocular surface application of hypertonic saline or exposure to bright light in urethane anesthetized male rats. The Vi/Vc and Vc/C1 regions are the main sites of termination for trigeminal afferent nerves that supply the ocular surface, while hypertonic saline (saline=0.15-5M) and bright light (light=5k-20klux) selectively activate ocular surface and intraocular trigeminal nerves, respectively, and excite second-order neurons at the Vi/Vc and Vc/C1 regions. Integrated OOemg activity, ipsilateral to the applied stimulus, increased with greater stimulus intensities for both modalities. Lidocaine applied to the ocular surface inhibited OOemg responses to hypertonic saline, but did not alter the response to light. Lidocaine injected into the trigeminal ganglion blocked completely the OOemg responses to hypertonic saline and light indicating a trigeminal afferent origin. Synaptic blockade by cobalt chloride of the Vi/Vc or Vc/C1 region greatly reduced OOemg responses to hypertonic saline and bright light. These data indicate that OOemg activity evoked by natural stimuli known to cause irritation or discomfort in humans depends on a relay in both the Vi/Vc transition and Vc/C1 junction regions.

Abstract
This study was carried out to isolate, identify and characterize Escherichia coli from diarrheic calves, their prevalence and antibiotic sensitivity pattern during the period from November 2011 to December 2012. For this purpose 100 diarrheic fecal samples were collected from four different areas of Bangladesh. The samples were aseptically collected and brought to the laboratory of Medicine, Faculty of Veterinary Science, Bangladesh Agricultural University, Mymensingh. The organisms were identified as E. coli on the basis of cultural, morphological and biochemical characteristics. Further the isolated bacteria were confirmed by amplification of E. coli specific 16sRNA gene. The antibiotic resistant pattern of the isolates was also performed. Out of 100 samples 49 (49%) were found to be positive for E. coli. The highest prevalence was found in Shahjadpur, Sirajganj (53.33%) while lowest was in BAU, Mymensingh (40%). The antibiogram study revealed that all isolates were resistant against ampicillin, erythromycin, azithromycin and streptomycin where erythromycin was 100% resistant, whereas 100% sensitivity was found to tetracycline and gentamicin which might be the best choice of drug for the treatment of diarrheagenic E. coli causing colibacillosis in calves.DOI: http://dx.doi.org/10.3329/bjvm.v11i2.19139Bangl.

Abstract
Single-visit root canal therapy is one of the reality in modern endodontics globally, both for vital and non-vital teeth, despite many research efforts and much controversy, specially when post-operative pain is concerned. There are increased post-operative complications as pain, swelling, discomfort in managing teeth having symptomatic pulpal pathosis. To clinically verify the possibility to treat symptomatic vital and non-vital teeth in one visit technique, 126 patiens were selected and advised to undergone single visit endodontic treatment at the Department of Conservative Dentistry and Endodontics, Bangabandhu Sheikh Mujib Medical University, Dhaka. Endodontically involved symptomatic vital and symptomatic non-vital teeth were enrolled in two groups and advised to undergone single visit endodontic treatment. Both groups were assessed at 24 hours, 48 hours, 72 hours and long term post operative evaluation up to 10 months. The main outcome measure was post operative pain. The result of our study indicates that single visit root canal treatment is a safe, effective and practical method of treatment of an endodontically involved tooth both in vital and non vital cases when applied in appropriate situation. Significantly fewer patients of symptomatic vital cases reported pain in immediate follow up i.e. 24 hours, 48 hours and 72 hours in comparison to non vital cases (12.69% vs. 22.2%, 4.16% vs. 11.11%, 1.58% vs. 7.93%). At 10 months of long term follow up the recall rate was 74.35% and 90(71%) of patients were comfortable after receiving treatment. Post operative pain incidence in single visit was equivalent to that of multi visit endodontics, provided one had an accurate diagnosis, proper case selection and skilled technique.

Abstract
This cross-sectional study was carried out at Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka Medical College Hospital (DMCH), National Institute of Kidney Diseases & Urology (NIKDU) and Kidney Foundation from July 2005 to June 2007 to find the cardiovascular complications in end stage renal disease (ESRD) patients on maintenance haemodialysis. Patients of both sexes with age ranging from 18-59 years and getting at least 8 hours of haemodialysis per week for the last 3 months were enrolled in the study. A total of 126 such patients were included in the study. Among 126 patients 77(61.1%) developed some types of cardiovascular complications. In terms of type of complications 63.6% of the patients had LVH, 23.4% had ischemic heart disease (IHD) and 10.4% had congestive heart failure (CCF) and 2.6% cardiomyopathy. Over 96% patients were hypertensive, followed by 46.8% diabetics and 42.1% smokers. Presence of hypertension, diabetes, family history of diabetes and hypertension were observed to be significantly higher in patients who developed cardiovascular complications (p<0.05). It is deserved that cardiovascular complications (CVC) are very common in ESRD patients on maintenance haemodialysis (MHD). Poor control of blood pressure, low Haemoglobin level and poor glycaemic control are higher in ESRD patients on MHD and are possibly related to the development of cardiovascular complications.

Abstract
BACKGROUND Type1 diabetes mellitus (T1DM) results from auto- immune destruction of insulin-producing β cells and is characterized by the presence of insulitis and β-cell autoantibodies. Up to one third of patients develop an autoimmune polyglandular syndrome (APS). Presence of other autoimmune disorders in patients with T1DM has been associated with increased morbidity and mortality. Hypoglycemia resulting from concurrent hypothyroidism or adrenal crisis can be dangerous; starting replacement therapy for hypothyroidism may result in adrenal crisis if background hypocortisolism is not recognized. Early detection of antibodies and latent organ-specific dysfunction is advocated to alert physicians to take appropriate action in order to prevent full-blown disease. AIMS The objectives of this study were to assess the concurrence of various autoimmune disorders in patients with T1DM, to review the concept and detect the overt forms of Autoimmune Thyroid Disease (AITD), Addison's Disease (AD), Vitamin B 12, vitiligo in T1DM and to find their correlation according to age and sex of the patients. METHODS It is a retrospective study where medical records between January 2007-June 2010 of all the patients diagnosed with T1DM, followed up at Department of Endocrinology were reviewed to find out the presence of (AD), AITD, vitiligo, Vitamin B12 deficiency and Primary Gonadal Failure, which were diagnosed clinically with available investigational procedures. RESULTS A total of 100 cases of T1DM were evaluated during the present study. The age group of patients ranged from 8 to 40 years, with the average being 21.56 years. 64% of the patients were males and the rest were females. 29 % of T1DM subjects had AITD (Hashimoto's or Graves'disease), 5% were diagnosed with Vitamin B12 deficiency, 4% had AD, and 6% showed Vitiligo. 28 % had family history of autoimmune endocrinopathy. CONCLUSION The commonest autoimmune disorder associated with T1DM found in our study was AITD. Because genetic/ autoantibodies testing is not a feasible option, it is important to screen them with best available laboratory facilities and clinical assessment in view of high prevalence of associated autoimmune conditions.

Abstract
The study was undertaken to determine socio-demographic and reproductive risk factors associated with Chlamydia trachomaties IgM seropositivity during pregnancy. This cross sectional comparative study was carried out in the obstetrics outdoor of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh in collaboration with the department of Virology between the periods from July 2007 to December 2008. Pregnant women at their first visit to the hospital were approached consecutively and asked to complete a questionnaire and 2cc blood was collected from each subject for Chlamydia trachomatis IgM antibody testing using ELISA method. The study population was divided into two groups according to the presence and absence of serum Chlamydia trachomatis IgM antibody. Finally socio-demographic and reproductive risk factors were compared between the groups. Among 172 women the sero-prevalence of Chlamydia IgM was 41%. The multiple logistic regression model (step wise) finally extracted for characteristics correlated with seropositivity. Ten years or less (≤SSC) education (OR 2.6 95% CI 1.1to 5.9), history of adverse pregnancy outcome (OR 2.8 95% CI 1.2 to 6.5) and multiple sex partner of husband (OR 4.1 95% CI 1.2 to 14.8) were associated with chlamydia infection. The use of condom (OR 0.28 95% CI 0.12 to 0.63) was associated with decreased risk of infection. Chlamydia trachomatis infection during pregnancy is associated with risk factors on the basis of which selective screening can be done.

Abstract
In recent years, the incidence of therapy-related myelodysplastic syndrome (t-MDS) and therapy-related acute myeloid leukemia (t-AML) that occur during chemotherapy for ovarian cancer has increased. While alkylating agents and topoisomerase II inhibitors are particularly mutagenic and have strong leukemogenic potential, paclitaxel and combination chemotherapy/radiation therapy also appear to induce t-MDS. The present authors report a case of t-MDS that developed during chemotherapy and radiation therapy for ovarian cancer. The patient was a 75-year-old woman who received six courses of cyclophosphamide/doxorubicin/cisplatin (CAP) therapy after initial surgery for Stage IIIc grade ovarian cancer in 1995. Beginning in February 2005, the patient experienced multiple recurrences due to sternal metastasis. Chemotherapy, including paclitaxel and carboplatin (TC), was administered intermittently and was combined with radiation therapy to a sternal metastatic lesion. Pancytopenia was observed in December 2008, and she was diagnosed with t-MDS (WHO subtype, refractory cytopenias with multilineage dysplasia [RCMD]): the time from first chemotherapy to t-MDS onset was 106 months. Without evidence of blast crisis, the recurrent lesions continued to grow and caused multiple cerebral infarctions, from which she eventually died. The cumulative doses of paclitaxel and carboplatin administered to this patient were 1,968 mg and 6,480 mg, respectively.

Abstract
The p63 gene regulates thymic epithelial cell (TEC) proliferation, whereas FoxN1 regulates their differentiation. However, their collaborative role in the regulation of TEC homeostasis during thymic aging is largely unknown. In murine models, the proportion of TAp63(+), but not ΔNp63(+), TECs was increased with age, which was associated with an age-related increase in senescent cell clusters, characterized by SA-β-Gal(+) and p21(+) cells. Intrathymic infusion of exogenous TAp63 cDNA into young wild-type (WT) mice led to an increase in senescent cell clusters. Blockade of TEC differentiation via conditional FoxN1 gene knockout accelerated the appearance of this phenotype to early middle age, whereas intrathymic infusion of exogenous FoxN1 cDNA into aged WT mice brought only a modest reduction in the proportion of TAp63(+) TECs, but an increase in ΔNp63(+) TECs in the partially rejuvenated thymus. Meanwhile, we found that the increased TAp63(+) population contained a high proportion of phosphorylated-p53 TECs, which may be involved in the induction of cellular senescence. Thus, TAp63 levels are positively correlated with TEC senescence but inversely correlated with expression of FoxN1 and FoxN1-regulated TEC differentiation. Thereby, the p63-FoxN1 regulatory axis in regulation of postnatal TEC homeostasis has been revealed.

Abstract
The present study was designed to know the landing and distribution pathways of fish and types and nature of stakeholders involved in fish distribution chain in Bangladesh. A total of 237 fish landing centers and 5440 markets were detected. The number of landing center and market were highest in Chittagong and Dhaka division respectively. Stakeholders in fish distribution, viz., arotdars, paikers and retailers were found to be 6219, 39506 and 122922, respectively. A 84.71% of the landing centers were found to be operated year round while 15.29% were seasonal. The major fish production zones and major gateways of the country where inland capture and culture and marine capture fish landed were identified. In any locality 62.83% of the landed fish were transported within 100 km area and 5.73% of fish were transported beyond 500 km. The quantity of fish harvested from river, beel, Kaptai lake floodplain, pond, baor, coastal area/sea and shrimp/prawn farm were 5.25, 4.41, 0.13, 35.03, 38.22, 0.23, 10.93 and 5.80%, respectively. The common constraints identified were lack of adequate infrastructure facilities in the landing center and market, unhygienic environment, influence of middlemen, money lending at high rate etc. For the betterment of fish landing and distribution, appropriate authority should pay proper attention so that both quality and fair price are ensured.

Abstract
Lumber spinal canal stenosis is an important cause of low back pain and it frequently presents with low backache with neurogenic claudication. Operative management of lumbar spinal canal stenosis by decompression surgery is an effective method. This prospective interventional (quasi experimental) study was performed in patient having history of characteristic clinical features like low backache with radicular pain, neurogenic claudication, signs of root compression, positive MRI findings attending in the department of Orthopaedic Surgery and Neurosurgery, Dhaka Medical College Hospital and NITOR. Dhaka, from July 2008 to June 2010. Thirty patients were evaluated among those 18(60%) were 50 years and above. Male to female ratio was roughly 9:1. About 87% of the patients had sensory deficit and 50% had neurogenic claudication. Majority (83.3%) of the patients at presentation had a suffering of 12 or >12 months. Diagnosis shows that 3.5% of patients had L4 lesion, 60% L5, 6.5% patients had L4 & L5 and 30% S1. Laminectomy was done in 43.3% of patients, laminectomy and disectomy in 30% and laminectomy, discectomy & foraminal decompression in 26.7% of patients. Relief of symptoms occurred in 25(83.5%) of patients. Over three-quarter (76.7%) of patients exhibited minimal disability and 23.3% moderate disability based on Oswestry Disability Index, while by MacNab criteria, most (80%) of patients was excellent, 10% good and another 10% fair. Repeated measure ANOVA statistics showed that mean Oswestry score decreased significantly from 54.5% at baseline to 22% at the end of 1 year (p<0.001).

Abstract
Accurate estimation of the glomerular filtration rate (GFR) is essential for the evaluation of patient with chronic kidney disease (CKD). The present study was a comparison between modified gates GFR with laboratory measured CCR & MDRD formula based estimated GFR method. Pre-diagnosed 180 diabetic nephropathy patients were selected. All the time of evaluation the blood glucose of the patients were controlled and serum creatinine was stable. Then CCR was done and GFR was estimated by Modified Gates method & MDRD method. All the patients were categorized in 5 stages of CKD. They were matched for age, BMI, blood pressure, duration of diabetes, the blood sugar and HbA1C levels. The Gates GFR in stage-2 (70±13) & stage-3 (48±12) was closer with MDRD in stage-2 (77±8) and stage 3 (43±7). The CCR is closer in stage-1 (110±52) & stage-4 (30±10) with MDRD in stage-1 (112±13) and stage-4 (21±4). Association study showed MDRD GFR had highest correlation with Gates GFR (r=0.86; p<0.05). The estimation of glomerular filtration rate (GFR) in different methods varied significantly between each other at different stages of chronic kidney disease (CKD) in type 2 diabetic nephropathy subjects.

Abstract
Recirculation is an important issue in haemodialysis (HD) patients as increased percent recirculation causes decreased dialysis delivery of the patients. The purpose of the study was to determine the amount and factors of recirculation in those patients. The study was a cross sectional one carried in the Department of Nephrology, Dhaka Medical College and Hospital during October 2010 to September 2011. A total of 118 end stage renal disease patients with arterio-venous fistula who were on HD for more than 3 months were purposively selected. The degree of recirculation was measured with urea based two needle technique method. For each patient distances between arterial and venous and distances of needles from fistula and its directions were recorded. Echocardiography and A-V fistula Colour Doppler Ultrasound were also performed. The mean A-V fistula recirculation was 8.1 +/- 5.5% with a range 0-66%. The most common factors were close proximity and improper arterial and venous needles placement. No difference was observed between diabetic and non diabetic also between hypertensive and normotensive. A-V fistula recirculation is common occurrence in HD patients and the most common factors of recirculation are misplacement and close proximity of needles therefore emphasis should be given on education and training of HD staffs.

Abstract
Infections with Streptococcus pyogenes exhibit a wide spectrum of infections ranging from mild pharyngitis to severe Streptococcal toxic shock syndrome (STSS). The M1 serotype of Streptococcus pyogenes is most commonly associated with STSS. In the present study, we hypothesized that Rac1 signaling might regulate M1 protein-induced lung injury. We studied the effect of a Rac1 inhibitor (NSC23766) on M1 protein-provoked pulmonary injury. Male C57BL/6 mice received NSC23766 prior to M1 protein challenge. Bronchoalveolar fluid and lung tissue were harvested for quantification of neutrophil recruitment, edema and CXC chemokine formation. Neutrophil expression of Mac-1 was quantified by use of flow cytometry. Quantitative RT-PCR was used to determine gene expression of CXC chemokines in alveolar macrophages. Treatment with NSC23766 decreased M1 protein-induced neutrophil infiltration, edema formation and tissue injury in the lung. M1 protein challenge markedly enhanced Mac-1 expression on neutrophils and CXC chemokine levels in the lung. Inhibition of Rac1 activity had no effect on M1 protein-induced expression of Mac-1 on neutrophils. However, Rac1 inhibition markedly decreased M1 protein-evoked formation of CXC chemokines in the lung. Moreover, NSC23766 completely inhibited M1 protein-provoked gene expression of CXC chemokines in alveolar macrophages. We conclude that these novel results suggest that Rac1 signaling is a significant regulator of neutrophil infiltration and CXC chemokine production in the lung. Thus, targeting Rac1 activity might be a potent strategy to attenuate streptococcal M1 protein-triggered acute lung damage.

Abstract
Abstract Platelets play an important role in abdominal sepsis and P2Y12 receptor antagonists have been reported to exert anti-inflammatory effects. Herein, we assessed the impact of platelet inhibition with the P2Y12 receptor antagonist ticagrelor on pulmonary neutrophil recruitment and tissue damage in a model of abdominal sepsis. Wild-type C57BL/6 mice were subjected to cecal ligation and puncture (CLP). Animals were treated with ticagrelor (100 mg/kg) or vehicle prior to CLP induction. Edema formation and bronchoalveolar neutrophils as well as lung damage were quantified. Flow cytometry was used to determine expression of platelet-neutrophil aggregates, neutrophil activation and CD40L expression on platelets. CLP-induced pulmonary infiltration of neutrophils at 24 hours was reduced by 50% in ticagrelor-treated animals. Moreover, ticagrelor abolished CLP-provoked lung edema and decreased lung damage score by 41%. Notably, ticagrelor completely inhibited formation of platelet-neutrophil aggregates and markedly reduced thrombocytopenia in CLP animals. In addition, ticagrelor reduced platelet shedding of CD40L in septic mice. Our data indicate that ticagrelor can reduce CLP-induced pulmonary neutrophil recruitment and lung damage suggesting a potential role for platelet antagonists, such as ticagrelor, in the management of patients with abdominal sepsis.

Abstract
BACKGROUND AND OBJECTIVES Platelet-derived CD40L is known to regulate neutrophil recruitment and lung damage in sepsis. However, the mechanism regulating shedding of CD40L from activated platelets is not known. We hypothesized that matrix metalloproteinase (MMP)-9 might cleave surface-expressed CD40L and regulate pulmonary accumulation of neutrophils in sepsis. METHODS Abdominal sepsis was induced by cecal ligation and puncture (CLP) in wild-type and MMP-9-deficient mice. Edema formation, CXC chemokine levels, myeloperoxidase levels, neutrophils in the lung and plasma levels of CD40L and MMP-9 were quantified. RESULTS CLP increased plasma levels of MMP-9 but not MMP-2. The CLP-induced decrease in platelet surface CD40L and increase in soluble CD40L levels were significantly attenuated in MMP-9 gene-deficient mice. Moreover, pulmonary myeloperoxidase (MPO) activity and neutrophil infiltration in the alveolar space, as well as edema formation and lung injury, were markedly decreased in septic mice lacking MMP-9. In vitro studies revealed that inhibition of MMP-9 decreased platelet shedding of CD40L. Moreover, recombinant MMP-9 was capable of cleaving surface-expressed CD40L on activated platelets. In human studies, plasma levels of MMP-9 were significantly increased in patients with septic shock as compared with healthy controls, although MMP-9 levels did not correlate with organ injury score. CONCLUSIONS Our novel data propose a role of MMP-9 in regulating platelet-dependent infiltration of neutrophils and tissue damage in septic lung injury by controlling CD40L shedding from platelets. We conclude that targeting MMP-9 may be a useful strategy to limit acute lung injury in abdominal sepsis.

Abstract
AIMS To evaluate HbA(1c) as a tool for the diagnosis of diabetes and pre-diabetes (impaired glucose tolerance and/or impaired fasting glucose) and to identify the optimal cut-off values suitable for a Bangladeshi population. METHODS In this cross-sectional survey in a rural community, 2293 randomly selected individuals aged ≥ 20 years without prior history of diabetes were included. HbA(1c) and other clinical covariates necessary for the diagnosis of diabetes were recorded. Diabetes and pre-diabetes were defined according to the World Health Organization 1999 criteria. The receiver operating characteristic curve was used to determine the performance of HbA(1c). RESULTS The prevalences of diabetes and pre-diabetes were 7.9 and 8.6%, respectively. Based on receiver operating characteristic curve analysis, an HbA(1c) cut-off value of ≥ 42 mmol/mol (≥ 6.0%) gave an optimal sensitivity of 86.2% and specificity of 93.3%, with an area under the curve of 0.949 to predict diabetes using the oral glucose tolerance test as the gold standard; a cut-off value of ≥ 38 mmol/mol (≥ 5.6%) gave an optimal sensitivity of 68.0% and specificity of 66.4%, with an area under the curve of 0.714 to predict pre-diabetes. In subjects at high risk of diabetes, HbA(1c) ≥ 42 mmol/mol (≥ 6.0%) showed higher sensitivity than fasting plasma glucose ≥ 7.0 mmol/l, 2-h plasma glucose ≥ 11.1 mmol/l and HbA(1c) ≥ 48 mmol/mol (≥ 6.5%). CONCLUSIONS An HbA(1c) cut-off value of ≥ 42 mmol/mol (≥ 6.0%) was highly sensitive and specific in diagnosing diabetes mellitus. This optimal cut-off level may be suitable as a diagnostic criterion for diabetes in a Bangladeshi population.

Abstract
Overwhelming accumulation of neutrophils is a significant component in septic lung damage, although the signaling mechanisms behind neutrophil infiltration in the lung remain elusive. In the present study, we hypothesized that geranylgeranylation might regulate the inflammatory response in abdominal sepsis. Male C57BL/6 mice received the geranylgeranyl transferase inhibitor, GGTI-2133, before cecal ligation and puncture (CLP). Bronchoalveolar lavage fluid and lung tissue were harvested for analysis of neutrophil infiltration, as well as edema and CXC chemokine formation. Blood was collected for analysis of Mac-1 on neutrophils and CD40L on platelets. Gene expression of CXC chemokines, tumor necrosis factor-α (TNF-α), and CCL2 chemokine was determined by quantitative RT-PCR in isolated alveolar macrophages. Administration of GGTI-2133 markedly decreased CLP-induced infiltration of neutrophils, edema, and tissue injury in the lung. CLP triggered clear-cut upregulation of Mac-1 on neutrophils. Inhibition of geranylgeranyl transferase reduced CLP-evoked upregulation of Mac-1 on neutrophils in vivo but had no effect on chemokine-induced expression of Mac-1 on isolated neutrophils in vitro. Notably, GGTI-2133 abolished CLP-induced formation of CXC chemokines, TNF-α, and CCL2 in alveolar macrophages in the lung. Geranylgeranyl transferase inhibition had no effect on sepsis-induced platelet shedding of CD40L. In addition, inhibition of geranylgeranyl transferase markedly decreased CXC chemokine-triggered neutrophil chemotaxis in vitro. Taken together, our findings suggest that geranylgeranyl transferase is an important regulator of CXC chemokine production and neutrophil recruitment in the lung. We conclude that inhibition of geranylgeranyl transferase might be a potent way to attenuate acute lung injury in abdominal sepsis.

Abstract
The mechanisms of leukocyte recruitment in the pulmonary microvasculature in response to local and systemic inflammation remain elusive. Male C57BL/6 mice received lipopolysaccharide (LPS) intrapulmonary (intratracheally, it) or systemically (intravenously, iv) for 1–18 h. Leukocyte responses in lung were analyzed by use of intravital fluorescence microscopy. Plasma and lung levels of CXC chemokines as well as Mac-1 and F-actin expression in leukocytes and bronchoalveolar leukocytes were quantified. Venular leukocyte rolling was markedly increased in response to local LPS but only marginally after systemic LPS. Leukocyte adhesion in venules was enhanced in both groups although adhesion was higher in mice receiving LPS intratracheally compared with LPS intravenously. Systemic LPS caused more leukocytes trapping in capillaries compared with local LPS. The ratio of adherent leukocytes in venules compared with capillaries was higher in response to local LPS, suggesting that leukocytes were more prone to accumulate in venules in local inflammation and in capillaries in systemic inflammation. Systemic LPS triggered higher F-actin formation and Mac-1 expression in leukocytes compared with local LPS. Local and systemic LPS caused similar increases in CXC chemokines in the lung whereas intravenous endotoxin provoked higher levels of CXC chemokines in the circulation. Interestingly, intratracheal LPS increased recruitment of leukocytes in the alveolar space whereas intravenous LPS was ineffective in promoting leukocyte accumulation in the bronchoalveolar space. In conclusion, our data demonstrate that pulmonary microvascular recruitment of leukocytes differs in local and systemic inflammation, which might be related to premature activation and stiffening of circulating leukocytes in endotoxemia.

Abstract
BACKGROUND Diagnosis of visceral leishmaniasis (VL) is a major obstacle in the control of this disease. The rK39 strip-test using patient's blood is a breakthrough; however, it still requires a blood sample, which is a concern for safety in the field. We tried to simplify the test using the patient's urine instead of blood. AIMS To observe the sensitivity and specificity of the urine test in comparison with the blood test. MATERIALS AND METHODS We tested active and post-treatment VL patients, Post Kala azar dermal leishmaniasis (PKDL), VL/HIV and control subjects (healthy, disease suspects and diseased other than VL) with the rK39 strip-test using blood and urine samples. STATISTICAL ANALYSIS The level of agreement between the urine and blood testing was calculated by inter-rater agreement (kappa) statistics. RESULTS Forty-two active VL, 40 treated VL, six PKDL, three VL/HIV and 139 controls (54 healthy, 21 disease suspects and 64 diseased other than VL) were tested. All VL-related cases showed positive results with urine as well as blood samples (100%). The urine testing was found to have 100% sensitivity and 86.33% specificity for the diagnosis of VL. Kappa statistic between the two methods was 0.916 (P<0.001). Urine testing had more false-positive results in comparison with blood testing (13.67% vs. 9.45%), but the test subjects were from VL-endemic areas and they might be exposed to Leishmania donovani infection. CONCLUSIONS The present study has the potentiality of providing a new, yet simplest non-invasive screening tool for VL in remote rural areas.

Abstract
The Platelet (PLT) Transfusion Therapy plays an important role in the support of surgical, haematological, oncological and transplant patients. The present study was assigned to find out the post transfusion increment of platelet count among the thrombocytopenic patients in Bangladeshi population. This descriptive study was conducted at the Departments of Haematology and Transfusion Medicine, BSMMU, Dhaka. Total 42 thrmbocytopenic patients were randomly assigned to receive a transfusion when their platelet counts below 10000 per cubic millimeter or with active bleeding. Pre transfusion and post transfusion platelet count were measured in all patients. Out of 42 patients, 26(61.90%) were male and 16(38.10%) were female. Leukemia was the most common cause of thrombocytopenia (47.62%). Most of the patients (71.34%) required transfusion of multiple units of platelet and 12(28.57%) patients required double units. Before transfusion of platelet concentrate <30×10⁸/L, 30-80×10⁸/L and >80×10⁸/L platelet count were found in 30(71.43%), 08(19.05%) and 04(09.52%) patients respectively. After transfusion of platelet concentrate <50×10⁸/L, 50-100×10⁸/L and >100×10⁸/L platelet count were found in 30(71.43%), 08(19.05%) and 04(09.52%) patients respectively. In all patients post transfusion platelet count increases but 2 or multiple units of transfusion were needed.

Abstract
A cross-sectional study was conducted among youth clients of hotel-based female sex workers (YCHBFSWs) in nine randomly selected hotels in Bangladesh to examine sexual-risk behaviour, condom use and determinants of condom use in last sex, knowledge of HIV, sexually transmitted infection (STI) prevalence and STI care-seeking behaviour. A prestructured questionnaire was used to collect sociodemographic, behavioural, clinical information; urine specimens (before sex) and blood were collected for diagnosis of Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, syphilis and herpes simplex virus 2 (HSV2) infection. One thousand and thirteen participants were enroled in the study. Approximately half of them reported visiting female sex workers (FSWs) at least once a month and 25% visited FSWs at least once a week. Only 12% of participants reported regular condom use. The prevalence of N. gonorrhoeae, C. trachomatis, T. vaginalis, syphilis and HSV2 was 2.2%, 3.9%, 7.2%, 2.6% and 12.9%, respectively. Only 15.3% of the YCHBFSW sought STI care in the past year. Negotiation of condom use with FSWs was the main determinant (odds ratio = 17.95) for condom use at last sex. Male clients of FSWs, including YCHBFSW, are an important bridge population for HIV transmission in Bangladesh and HIV interventions should be designed and implemented for them.

Abstract
BACKGROUND Intestinal injury is a key feature in sepsis. Inhibitors of heat shock protein 90 (Hsp90) have been shown to exert protective effects in models of inflammation. Herein, we hypothesized that Hsp90 might regulate intestinal inflammation and leakage in abdominal sepsis. MATERIALS AND METHODS Male C57BL/6 mice were pretreated with radicicol (60 mg/kg), which is a specific inhibitor of Hsp90, prior to cecal ligation and puncture (CLP). Intravital fluorescence microscopy was used to quantify leukocyte-endothelium interactions in the colonic microcirculation 6 h after CLP. Colonic tissue was harvested to determine levels of myeloperoxidase, tumor necrosis factor-α and CXC chemokines. Intestinal injury was examined by histology. Intestinal barrier function was quantified by leakage of fluorescein isothiocyanate-dextran from the vascular system out into the abdominal cavity after intravenous injection. RESULTS We found that radicicol significantly decreased CLP-induced leukocyte rolling and adhesion in colonic venules. Inhibition of Hsp90 reduced colonic levels of myeloperoxidase by 24% in septic animals. Moreover, radicicol significantly decreased CLP-provoked formation of CXC chemokines but had no significant effect on tumor necrosis factor-α levels in the colon. Notably, Hsp90 inhibition significantly attenuated intestinal tissue injury evoked by CLP. Lastly, it was found that radicicol reduced sepsis-induced intestinal leakage by 43%. CONCLUSION Our novel findings suggest that targeting Hsp90 protects against intestinal inflammation and leakage and might be a useful strategy to ameliorate intestinal failure in polymicrobial sepsis.

Abstract
Hydropericardium syndrome (HPS) is a disease of poultry that is caused by fowl adenovirus-4. Inactivated liver homogenate from diseased birds is still the choice of vaccine in some countries which disseminates numerous pathogens along with inactivated virus. Moreover incomplete attenuation or inactivation, reversion to virulence and the oncogenic potential/genetic instability of the adenoviruses have prevented their use in routine vaccines. To address this problem an effort is made to develop a subunit vaccine. For this purpose penton base protein of HPS virus was expressed in Escherichia coli and used as subunit vaccine in broilers. Immunogenicity of the recombinant penton base protein and challenge protection test against pathogenic virus demonstrated the ability of recombinant penton base protein to confer (90%) protection. Results suggest that the recombinant penton base protein is a candidate for subunit vaccine against HPS.

Abstract
A series of substituted 1,3,4-oxadiazole derivatives 19-34 were synthesized as antiinflammatory agents. The target compounds were obtained by cyclodesulfurization of the corresponding thiosemicarbazides 3-18 using either dicyclohexylcarbodiimide DCC, or I(2)/NaOH. Intermediates 3-18 are readily accessible through conversion of the carboxylic acids 1a-d to the respective hydrazides 2a-d followed by treatment with appropriate isothiocyanate derivatives. The structures of the synthesized compounds were confirmed by elemental as well as spectroscopic analyses. The antiinflammatory activity was investigated by determination of the inhibitory effects of the oxadiazole derivatives 19-34 on histamine-induced edema in rat abdomen. Compounds 19a, 21a, 23b, 28c and 32d proved to be more potent antiinflammatory agents at 200 mg/kg po than ibuprofen, the standard reference drug. Other compounds such as 20a, 25b, 27c, 29c, and 33d showed significant antiinflammatory activity but less than ibuprofen at the same dose level. The low toxicity of the most potent compounds was reflected by their higher LD(50) value, ranging from ~1000 to 1500 mg/kg, as well as the lower ulcerogenic liability at 200 mg/kg po. Furthermore, some of the newly synthesized derivatives were better analgesics than the reference drug as observed from the percentage writhing inhibition in the p-benzoquinone (PBQ)-induced writhing test in mice.
