Abstract
Indian major carps are the widely consumed fish species of Pakistan, being a cheap source of proteins and unsaturated fatty acids, they are good for cardiovascular health. Water pollution due to discharge of untreated industrial waste water into water bodies contaminates this precious source of nutrients. The present study therefore, was aimed to assess deterioration of fatty acid profile of three Indian major carp species due to different concentrations of industrial wastes. The water samples were collected from the river Chenab at the site where it receives industrial wastewater via Chakbandi drain. After exposure to 1.5%, 3.0%, and 4.5% dilutions of collected water in different aquaria it was observed that proportion of unsaturated fatty acids in selected fish species were decreased significantly as the intensity of the dose increased (P < 0.05). Conversely the level of saturated fatty acids increased with the increasing dose of treatment (P < 0.05). These findings suggest that untreated wastewater not only deteriorate the fatty acid profile of aquatic animals but also these toxic substances can reach human body through fish meat and pose further health hazards. Therefore, it is highly recommended that industrial effluents should be treated before they are dumped into water bodies.

Abstract
Abstract Untreated sewage and industrial wastes from Faisalabad city are disposed to River Chenab through Chakbandi Main Drain (CMD). The present project is planned to investigate the effects of this freshwater pollution on the body of fish Ictalurus punctatus. The specimens of this fish species were collected upstream and downstream of the entrance of CMD into River Chenab. Fish gills, liver, kidney and muscles from dorsolateral regions of fish were subjected to histopathology. Farmed fish and fish from upstream areas were used as control. Fish collected from polluted experimental sites showed significant damage in selected organs. Gill tissues showed an abnormality in the form of an uplifting of the primary epithelium, fusion, vacuolation, hypertrophy, and necrosis. While liver tissues subjected to hepatocytes degeneration, necrosis, mitochondrial granular hepatocyte, and sinusoids dilation. Kidney tissues indicated increased bowmen space and constricted glomerulus and degenerated nephrons. Edema, necrosis, and atrophy were observed in muscle tissues of fish from polluted areas. Fish from the upstream area showed fused gill lamellae, inflammatory cell infiltration, hypertrophy and vacuolation in hepatocytes. Kidney tissues indicated the presence of nuclear tubular cells, destructive renal tubules, hemorrhage, and necrosis at tubular epithelium. Intra myofibril spaces were also observed in muscles. Specimens of control fish indicated no variation in gills, liver, kidney, and muscles. The present study revealed a strong correlation between the degree of tissue damage and environmental contamination. Present findings also compel global warnings to protect our water bodies and fish to rescue the human population.

Abstract
Physids belong to Class Gastropoda; belong to Phylum Mollusca and being bioindicators, intermediate hosts of parasites and pests hold a key position in the ecosystem. There are three species of Genus Physa i.e. P. fontinalis, Physa acuta and P. gyrina water bodies of Central Punjab and were characterized on the basis of molecular markers High level of genetic diversity was revealed by polymorphic RAPD, however SSR markers were not amplified. The multivariate analysis revealed polymorphism ranging from 9.09 percent to 50 percent among the three Physid species. Total number of 79 loci were observed for the three species under study and 24 loci were observed to be polymorphic. These RAPD fragment(s) can be developed into co dominant markers (SCAR) by cloning and can be further sequenced for the development of the Physa species specific markers to identify the introduced and native species in Pakistan.

Abstract
Physids belong to Class Gastropoda; Phylum Mollusca have important position in food web and act as bio indicators, pests and intermediate host. Being resistant these are called cockroaches of malacology. Physid snails were collected from different water bodies of Faisalabad (Punjab) and were identified up to species using morphological markers. The morphometry of the specimens was carried out with the help of a digital Vernier caliper in millimeters (mm) using linear measurement of shell characters. Linear regression analysis of the AL/SW ratio vs AL and SL/SW ratio vs AL indicated that allometric growth exists only in Physa acuta when compared with P.gyrina and P. fontinalis. This study will lead to assess the status of the Physid species in Central Punjab. The Principal component analysis shows that the Component 1 (Shell Length) and component 2 (Shell Width) are the most prolific components and nearly 80 percent of the identification. The distance between P. acuta and P. fontinalis is 5.4699, P. acuta and P. gyrina is 7.6411, P. fontinalis and P. gyrina is 16.6080 showing that P. acuta resembles with P. fontinalis, and both these specimens donot resemble with P. gyrina. P.acuta is an invasive species and shows bioactivity making it a potent candidate for bioactive substances.

Abstract
Gastric cancer (GC) is one of the most common tumors and remains the second leading cause of cancer mortality in the world. The incidence of gastric carcinoma is declining in the last few years in some areas like USA, UK, Canada etc, because of reduction in chronic H. pylori infection, smoking, decrease use of smoked and salted food. The gastric carcinoma still remains a burden for Bangladesh as the prevalence of H. Pylori has not substantially decreases. Among the gastric carcinomas, adenocarcinomas are the most common type. So the study was performed to observe the location and histomorphologic pattern of Gastric and gastrooesophageal junction (GEJ) adenocarcinoma. This descriptive cross sectional study was carried out at the Department of Pathology, Dhaka Medical College, Dhaka, Bangladesh from January 2013 to December 2014. A total of 130 patients with primary gastric and GEJ adenocarcinomas were included in this study. All the cases were evaluated for routine histological examination. The age range of the patients was 17 to 80 years and male to female ratio was 2.25:1. Antrum is the most common (66.9%) site being affected, followed by GEJ (19.2%), body (13%) and fundus (0.76%). Tumors of the antrum and GEJ were found mostly in the late age. On macroscopic examination, the ulcerated tumor mass (69.2%) was most frequent then the others. Regarding histological examination, 84(64.6%) cases were intestinal type, 32(24.6%) diffuse and 14(10.8%) mixed type by Laurens classification. According to WHO classification, about half of the cases (49.2%) were tubular carcinoma and rest were others. Most of the intestinal type carcinoma (71.4%) was presented with moderately differentiated and 25.0% with well differentiated. Where as the diffuse type presented with poorly differentiated in 96.9% cases.

Abstract
This study was conducted to assess water pollution by examining DNA fragmentation in selected fish organs (kidney, liver, gills, and muscle tissue) from Wallago attu, Sperata sarwari, Vulgaris vulgaris, and Labeo rohita collected from a known polluted section of the Chenab River, Pakistan, and from a control site. The fish were caught using a gill net and were assigned to three different weight groups (W1, W2, and W3) to study the degree of variation in DNA fragmentation in relation to body weight. In fish from the polluted site, DNA fragmentation was higher in kidney, liver, gills, and muscles, compared to the control. No significant DNA fragmentation was observed in fish collected from the control site. Highly significant (P < 0.01) relationship between body weight and DNA fragmentation was found in the organs of fish procured at the contaminated site. DNA fragmentation in body organs was found to be affected by the concentrations of lead, copper, nickel, and cadmium in W. attu, S. sarwari, L. rohita, and V. vulgarus harvested from Chenab River. DNA fragmentation in different freshwater fish species is therefore a reliable biomarker of water pollution.

Abstract
Infections due to hepatitis A (HAV), hepatitis B (HBV), hepatitis C (HCV) and hepatitis E (HEV) viruses are the major causes of hepatitis and are associated with significant morbidity and mortality in developing countries like Bangladesh. The aim of this study was to assess the distribution pattern of serological markers in patients of acute viral hepatitis. This was a hospital based observational cross sectional study among purposively selected 107 patients admitted with acute viral hepatitis in the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from April 2017 to September 2017. Data were collected by face-to-face interview of the patients, clinical assessment and investigations of biochemical and serological parameters using a structured questionnaire. Descriptive analysis was done using the analytic software SPSS version 21.0. The mean age of the patients was 33.35±12.97 years. Majority was male (68.2%), Muslim (87.9%), married (72.9%) and came from urban area (63.6%) with different level of educational qualifications. The prevalence of viral hepatitis is higher in male (68.22%) than female (31.78%). The common clinical presentations were dark coloured urine (100.0%), yellow colouration of the sclera (100.0%), anorexia (90.6%), nausea/vomiting (79.4%) and abdominal pain (68.2%). Of the 107 patients, 51.40% (n=55) had acute viral E hepatitis, 36.40% (n=39) had acute viral B hepatitis, 12.15% (n=13) had acute viral A hepatitis. Mixed infection with both hepatitis E and A viruses was 1.87% (n=2). HEV and HBV are common in relatively older age while HAV is common in relatively younger age to cause acute viral hepatitis. The study revealed a high prevalence of HEV followed by HBV and HAV in the Bangladeshi population suspected of having suffered from acute viral hepatitis.

Abstract
Various bird pests caused severe economic losses to valuable crops and fruit orchards all over the world. Among the birds, house sparrow is also considered to cause heavy plunder, not only to seeds of crops but also seedlings especially in organic farming. In present study two bird repellents, methylanthranilate and anthraquinone tested against house sparrows on maize seeds and seedlings in aviary conditions. Trial group in aviary-I, the treated maize seeds and seedlings with different doses of both bird repellents, control group in aviary-II, untreated seeds and seedlings were provided for three hours in the early morning. In each aviary, two closed circuit cameras were also installed to monitor the behavioral responses against different concentrations of both chemical repellents. Statistical analysis showed that there existed highly significant (P<0.01) variations among the trial and control groups for seeds and seedlings. By comparing both repellents, significant (P<0.05) differences were detected and anthraquinone showed better efficacy when compared to methylanthranilate, but in maize seedlings both repellents equal repellent properties. Non-significant (P>0.05) differences were observed in different grading of both natural chemical repellents for maize seeds while significant (P<0.05) variations were noticed for maize seedlings when provided to sparrows. By videotaped behavior sparrows presented manifest head juddering and feather upsetting activities by consumption of treated seeds and seedlings with higher concentrations of both natural bird repellents.

Abstract
Tinea corporis & cruris are one of the earliest known fungal infection and are very common throughout the world. Although tinea corporis and tinea cruris does not cause mortality but causes morbidity and poses a major health problem. This study was conducted to evaluate the Comparative Efficacy of Terbinafine and Fluconazole in the Treatment of Tinea corporis and Tinea cruris. This cross sectional comparative type of analytical study was carried out at the department of Pharmacology & Therapeutics with collaboration of Dermatology and Venereology in Mymensingh Medical College Hospital, Mymensingh, Bangladesh from January 2016 to December 2016. In this study 168 newly diagnosed Tinea corporis and Tinea cruris patient was purposively selected where pattern of comparative efficacy of terbinafine and fluconazole were analyzed. Among 168 patients most of the patients presented with tinea corporis (58.33%). Most patients belong to 21-30 years age group. Male female ratio in this study was 1.15:1. In this study 143 patients were treated by fluconazole 50mg once daily for 4 weeks and 25 patients were treated by terbinafine 250 mg once daily for 4 weeks. After 4 weeks, improvement rate by fluconazole was 86.02% and terbinafine 96.00%. The clinical score of both groups after 4th week of treatment, there was slight more reduction of clinical score in terbinafine using group than fluconazole using group. The difference between these two clinical score was not statistically significant (p>0.05). Although no significant difference was observed between these two groups of patient in clinical aspect, but due to its lower price and availability in the hospital, it is suggested that fluconazole is more suitable for the treatment of tinea corporis and tinea cruris.

Abstract
Hypertensive disorders are one of the most common disorders in pregnancy. They are amongst the major cause of maternal and perinatal morbidity and mortality. Incidence is increasing in developing countries like Bangladesh. This cross sectional descriptive study has done to observe the utilization of antihypertensive drugs in hypertensive disorders of pregnancy and conducted from January 2016 to December 2016 in the department of Pharmacology in collaboration with department of Gynecology and Obstetrics in Mymensingh Medical College Hospital, Mymensingh, Bangladesh. Non random purposive sampling technique was used. Total of 300 patients participated in the study, 281 anti partum and 19 postpartum. Age distribution showed 42% patients were in 21-25 years age group. Majority of the participants (91%) were housewife and majority (79%) came from poor socioeconomic status with below SSC education (68%). About 82% patients lived in rural area. Trimester and gravida wise distribution showed most of the participants were 3rd trimester (61%) and primigravida (57%) and only 6% patients belong to postpartum period. In this study preeclampsia was highest (63.8%) among all other types of hypertensive diseases in pregnancy. Majority of the patient were preferred for dual therapy (53%), mono therapy was used in 29% of cases. Most frequently given drug in pregnancy associated hypertension was methyldopa that is 88.33% (single 22.3%, combination 66%). Second most commonly used drug was nifidipine consisting of 47.6% but used in combination in all cases. Average number of anti hypertensive drugs prescribed per prescription was 1.87 and majorities (92%) were from essential drug list but used as trade name. Preeclampsia and eclampsia were more common among the hypertensive disorders in tertiary level hospital cases. Methyldopa was found to be the commonest prescribed antihypertensive in monotherapy and in combination.

Abstract
Eclampsia is an important cause of maternal mortality in developing countries. This cross-sectional comparative study was conducted in the Departments of Clinical Pathology, Bangabandhu Sheikh Mujib Medical University (BSMMU), and Obstetrics and Gynecology, BSMMU, and Dhaka Medical College Hospital, Dhaka, Bangladesh, from March 2012 to February 2013 and was designed to evaluate liver markers to predict preeclampsia. One hundred fifty (150) women with pregnancy of ≥28 weeks, 50 for each normal, preeclampsia and eclampsia group, were enrolled purposively. The protocol was approved by IRB of BSMMU. Consent was taken from each patient. Serum total Bilirubin and ALT were assessed. Data was collected in a questionnaire and analyzed by SPSS-16. Quantitative data were compared by ANOVA or 't' test and qualitative data by chi-square test. P value <0.05 was considered significant. The patients of all groups were similar in age and gravida. The mean±SD serum total bilirubin and ALT were significantly higher in preeclampsia and eclampsia groups than normal pregnancy. However they were similar in preeclampsia and eclampsia group.

Abstract
This prospective randomized study was done to compare operative time, intra-operative blood loss, post operative pain, secondary haemorrhage in common tonsillectomy methods. Thirty two (32) paediatric population of age 7-12 years from each group randomly selected, operative techniques adopted consecutively and this study was conducted in Bangabandhu Sheikh Mujib Medical University, Dhaka, Islami Bank Hospital, Dhaka, and Desh Medical Services, Chittagong, from January 2011 to December 2013. Surgery was performed by single midlevel surgeon. Postoperatively one month was followed the entire patient. Total 96 pediatrics population (32 for each group) was studied. Mean operating time and mean intra-operative blood loss was in cold dissection method 22 min and 15 ml, in bipolar dissection tonsillectomy 18 min and 10 ml & in laser tonsillectomy 17 min and 9 ml. Differences of operating time and variation of blood loss in various methods are not statistically significant. Laser and bipolar electro dissection tonsillectomy are popularized due to its relative less bleeding and quicker methods than that of cold dissection tonsillectomy; there is no significant difference among them.

Abstract
Several serum tumour markers have been described for gastric cancer. Preoperative level of tumor marker helps to predict the diagnosis of gastric carcinoma. CA72-4 as a serum tumour marker for gastric cancer is evaluated, and compared its utility in this regard with that of carcinoembryonic antigen (CEA). Analysis of gastric carcinoma by serum levels of CEA and CA72-4 and their correlation with histopathology help the clinician to develop his management strategies for gastric carcinoma. A prospective observational study was carried out in the Department of Clinical Pathology, Bangabandhu Sheikh Mujib Medical University (BSMMU) in collaboration with Department of Surgery BSMMU, DMCH, Delta Hospital Limited, Dhaka, during the period of October 2010 to September 2011. Serum CA72-4 and CEA were analyzed in 71 endoscopically suspected patients for gastric carcinoma. Among them 58 cases were diagnosed as malignant gastric disease and 13 cases were nonmalignant gastric disease. Sensitivity of CA 72-4 and CEA were 48.3% and 31% respectively and specificity were 92.3% and 76.9% respectively. In poorly differentiated carcinoma, positivity for CA72-4 and CEA were 55.6% and 36.1% respectively. Because of the high positivity of CA72-4 in poorly differentiated carcinoma, CA72-4 is reliable tumour marker in advanced cases. As the sensitivity of CA72-4 was more than that of CEA in diagnosis of gastric cancer, CA72-4 can be used in conjunction with other diagnostic tests like endoscopy that would be more helpful for the patients.

Abstract
We aimed to assess the bioaccumulation of selected four trace metals (Cd, Ni, Zn and Co) in four tissues (muscles, skin, gills and liver) of a freshwater fish Wallago attu (lanchi) from three different sites (upstream, middle stream and downstream) of the Indus River in Mianwali district of Pakistan. Heavy metal contents in water samples and from different selected tissues of fish were examined by using flame atomic absorption spectrometry. The data were statistically compared to study the effects of the site and fish organs and their interaction on the bioaccumulation pattern of these metals at P < 0.05. In W. attu the level of cadmium ranged from 0.004 to 0.24; nickel 0.003–0.708; cobalt 0.002–0.768 and zinc 47.4–1147.5 μg/g wet weight. The magnitude of metal bioaccumulation in different organs of fish species had the following order gills > liver > skin > muscle. The order of bioaccumulation of these metals was Ni < Zn < Co < Cd. Heavy metal concentrations were increased during the dry season as compared to the wet season. The results of this study indicate that freshwater fish produced and marketed in Mianwali have concentrations below the standards of FEPA/WHO for these toxic metals.

Abstract
Maternal PKU Syndrome (MPKU) is an embryopathy resulting from in utero phenylalanine (PHE) toxicity secondary to maternal phenylalanine hydroxylase deficient phenylketonuria (PKU). Clinical phenotypes in MPKU include mental retardation, microcephaly, in utero growth restriction, and congenital heart defects. Numerous in utero toxic exposures alter DNA methylation in the fetus. The PAH(enu2) mouse is a model of classical PKU while offspring born of hyperphenylalaninemic dams model MPKU. We investigated offspring of PAH(enu2) dams to determine if altered patterns of DNA methylation occurred in response to in utero PHE exposure. As neurologic deficit is the most prominent MPKU phenotype, methylome patterns were assessed in brain tissue using methylated DNA immunoprecipitation and paired-end sequencing. Brain tissues were assessed in E18.5-19 fetuses of PHE unrestricted PAH(enu2) dams, PHE restricted PAH(enu2) dams, and heterozygous(wt/enu2) control dams. Extensive methylome repatterning was observed in offspring of hyperphenylalaninemic dams while the offspring of PHE restricted dams displayed attenuated methylome repatterning. Methylation within coding regions was dominated by noncoding RNA genes. Differential methylation of promoters targeted protein coding genes. To assess the impact of methylome repatterning on gene expression, brain tissue in experimental and control animals were queried with microarrays assessing expression of microRNAs and protein coding genes. Altered expression of methylome-modified microRNAs and protein coding genes was extensive in offspring of hyperphenylalaninemic dams while minimal changes were observed in offspring of PHE restricted dams. Several genes displaying significantly reduced expression have roles in neurological function or genetic disease with neurological phenotypes. These data indicate in utero PHE toxicity alters DNA methylation in the brain which has downstream impact upon gene expression. Altered gene expression may contribute to pathophysiology of neurologic presentation in MPKU.

Abstract
Fecal occult blood test is the most widely used screening test for diagnosis of gastrointestinal bleeding disorders specially colorectal carcinoma. Among the various methods of fecal occult blood tests, chemical method is being used commonly, but the method has some drawbacks like low participation rate, high false positive rate, low sensitivity etc. To overcome these short comings, newer immunological method was introduced. This study evaluated the role of immunological method of fecal blood test in the diagnosis of occult lower GIT bleeding. Stool samples from two hundred patients were examined by both chemical and immunological method. The patients who were positive by any or both methods of occult blood test, were advised for colonoscopy. During colonoscopy tissues were taken for histopathology which was the gold standard of this study. Among 110 OBT positive patients pathological lesions were detected in 65 patients by colonoscopy and histopathology. The diseases detected by colonoscopy and histopathology 18 colorectal polyp, 8 colorectal cancer, 24 ulcerative lesions and 5 inflammatory bowel disease etc. Regarding comparative analysis of chemical and immunological method, the higher sensitivity (95.4% vs. 49.2%), specificity (44.4% vs. 37.8%), accuracy (74.5% vs. 44.5%), PPV (71.3% vs. 53.3%) and NPV (87% vs. 34%) of immunological method than chemical method was observed. Thus immunological method of fecal occult blood test was appeared to be a better alternative to conventional chemical method of fecal occult blood test in the diagnosis of occult lower GIT bleeding.

Abstract
Iron deficiency anemia is the common problem during pregnancy. Detection of iron deficiency early during pregnancy can reduce maternal and child mortality and morbidity. Red cell distribution width is a new routine parameter in fully automated hematology analyzer that can give the idea of early iron deficiency before other test. It gives the idea of red cell size variation which is the earliest morphologic changes in iron deficiency anemia. In prelatent and latent stage of iron deficiency MCV are normal. Whereas in latent stage Red Cell Distribution Width (RDW) would be expected to increase because of a microcytic population of cells appears in the blood. This study evaluates the role of red cell distribution width and RBC indices in determining iron deficiency early and provide reliable and useful technique. In this study 190 pregnant women were included. RDW, MCV, MCH, MCHC and iron profile were done. RDW compared with MCV, MCH and MCHC in various stages of iron deficiency. In latent stage of iron deficiency higher RDW was found significant than MCV, MCH, MCHC (p<0.05). In this study RDW had sensitivity 82.3% and specificity 97.4%. Whereas MCV, MCH and MCHC had 29.2%, 68.1% and 15% sensitivity but specificity was 98.7%, 83.1% and 96.1% in the detection of iron deficiency. Iron deficiency anaemia without other complicating disease could be screened out early by increased RDW when RBC indices were normal.

Abstract
Postoperative hypocalcaemia is the most frequent and common complication after total thyroidectomy. It is necessary to diagnose or to predict hypocalcaemia immediately after total thyroidectomy for minimizing complications. A prospective observational study was carried out in the Department of Clinical Pathology in collaboration with Department of Microbiology & Immunology, Department of Surgery, Department of Otolaryngology, Bangabandhu Sheikh Mujib Medical University (BSMMU) and Department of Otolaryngology, Dhaka Medical College & Hospital (DMC&H), Dhaka, during the period of September 2010 to August 2011 to evaluate intraoperative (20 minutes after total thyroidectomy) parathyroid hormone (PTH) measurement as a predictor of post thyroidectomy hypocalcaemia. Total 65 patients were enrolled in this study those came for total thyroidectomy. Postoperative hypocalcaemia developed in 25 cases. Intraoperative PTH was assessed and significant correlation was found between intraoperative PTH level and development of hypocalcaemia. The sensitivity, specificity, accuracy, positive predictive value, negative predictive value of intraoperative serum PTH for prediction of post total thyroidectomy hypocalcaemia were 84.0%, 85.0%, 84.6%, 77.8%, and 89.5% respectively. Because of the high sensitivity, specificity and accuracy of intraoperative serum PTH of this study, the early prediction of hypocalcaemia could be made by single assay of intraoperative serum PTH level at 20 minutes after total thyroidectomy.

Abstract
Iron deficiency anemia is common problem during pregnancy. Red cell size variation (anisocytosis) is the earliest morphologic changes in iron deficiency anemia. Red cell distribution width is a quantitative measure of red cell size variation and it can give the idea of early iron deficiency before other test to become positive. 190 pregnant women were included in this study. Red cell distribution width was compared between iron deficient & non-iron deficient pregnant women. Red cell distribution width also compared with Hb level, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration and peripheral blood film in prelatent iron deficiency, latent iron deficiency, mild and moderate iron deficiency anemia. Red cell distribution width had sensitivity 82.3% and specificity 97.4%. Whereas Hb level, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration and peripheral blood film all had 56.6%, 29.2%, 68.1%, 15% and 38.9% sensitivity but specificity was 90.9%, 98.7%, 83.1%, 96.1% and 98.7% in the detection of iron deficiency. Red cell distribution width appears to be a reliable and useful parameter for detection of iron deficiency during pregnancy.

Abstract
Neonatal septicemia is one of the major health problems throughout the world. Infections are frequent and important cause of morbidity and mortality in neonatal period. The objective of the present study was to find out the role of hematologic scoring system (HSS), C-reactive protein (CRP) and haptoglobin in the early diagnosis of neonatal septicemia. This is a descriptive consisted of 100 neonates admitted at neonatal ICU, BSMMU, who were clinically suspected sepsis. The hematological parameter, C-reactive protein and haptoglobin were measured in all cases. Blood culture was done as the gold standard for diagnosis of neonatal septicemia. There were 12 out of 100 neonates (12%) who had culture proven sepsis and they were predominantly preterm and very low birth weight. On evaluation of various hematological parameters total leukocyte count, total neutrophil count, immature to total neutrophil ratio (>0.2), immature to mature neutrophil ratio (>0.3), total immature count, platelet count were found to have optimal sensitivities and negative predictive values. Using these values hematologic scoring system (HSS) was formulated according to Rodwell et al. Score ≥4 was found sensitivity of 100%, specificity of 60%. C-reactive protein (CRP) had sensitivity of 75%, specificity of 74%. Haptoglobin was not found significant (p<0.05) with sepsis and sensitivity was very low. But Combination of score ≥4 and CRP showed sensitivity of 75%, specificity 85%, positive predictive value (PPV) 41% and negative positive value (NPV) 96%. HSS and CRP are useful test to differentiate the septicemic from non septicemic neonates and also provide a effective guideline to make decisions regarding judicious use of antibiotic therapy. But haptoglobin level was not found useful for screening of sepsis.

Abstract
Immature reticulocyte fraction a new routine parameter in the hematology analyzer can give the idea of the earliest morphologic change of bone marrow recovery before other test become positive after chemotherapy. A prospective observational study was carried out in the Department of Clinical Pathology in collaboration with Paediatric Haematology and Oncology, Bangabandhu Sheikh Mujib Medical University during a period of one year starting from October 2009 to September 2010 to evaluate the bone marrow recovery in children with acute lymphoblastic leukaemia by automated reticulocyte analysis. Total fifty patients were enrolled in this study on remission induction phase. All patients were between 8 months to 15 years age range with a mean age of 5.5 +/- 3.2. At the end of the study out of 50 cases, 52% patients showed early immature reticulocyte fraction recovery and concluded that the immature reticulocyte fraction parameter showed earlier haematopoietic recovery than the current practice of absolute neutrophil count recovery.

Abstract
The morphology of red cells by phase-contrast microscopy (PCM) is a useful diagnostic marker for glomerular haematuria. This study evaluated the value of urinary dysmorphic red cells and G1 cells (special type of dysmorphic red cell) count by PCM providing a simple, cost effective and low risk technique in the diagnosis of glomerular diseases. Urine samples of 120 patients with haematuria and proteinuria were examined and the percentage of dysmorphic red cells and G1 cells were calculated. Cases were divided into two groups; group I (>20% dysmorphic red cells- glomerular group) and group II (≤20% dysmorphic red cells as non glomerular group). Renal histopathology was used as the gold standard method for the diagnosis of glomerulonephritis. Results from PCM showed a sensitivity of 92.7%, specificity 100% by the detection of dysmorphic red cell while by the detection of G1 cells, a sensitivity of 97.6% and specificity 100% were observed. The percentage of G1 cells is superior to counting dysmorphic red cells. The high sensitivity of phase contrast microscopy confirms its usefulness for the detection of dysmorphic red cells and G1 cells that can guide clinicians in the identification of the site of haematuria using non invasive tests.

Abstract
Iron deficiency anaemia (IDA) and beta thalassaemia trait (BTT) are the most common causes of microcytic hypochromic anaemias. Several discrimination indices have been introduced to discriminate quickly these similar entities via parameters obtained from automated cell counter. The purpose of the study was to evaluate the value of five discrimination indices in differentiation of BTT and IDA. This study consists of 57 cases of BTT and 72 cases of IDA. Five discrimination indices evaluated in this study for differentiation of BTT and IDA were red blood cell (RBC) count, red blood cell distribution width index (RDWI), Green & King Index (G & K), Mentzer index (MI) and England & Fraser (E & F) index. Sensitivity, specificity, positive and negative predictive values and Youden's index (YI) had been calculated. RBC count and RDWI appears to be reliable and useful index for the differentiation of BTT and IDA, as both of the indices had more than 80% sensitivity, specificity in differentiation of IDA and BTT. Patients with microcytic hypochromic anaemia could be easily screened out for BTT and IDA through these discrimination indices in the absence of other complicated diseases.

Abstract
A two-dimensional steady convective flow of a micropolar fluid past a vertical porous flat plate in the presence of radiation with variable heat flux has been analyzed numerically. Using Darcy-Forchheimer model the corresponding momentum, microrotation and energy equations have been solved numerically. The local similarity solutions for the flow, microrotation and heat transfer characteristics are illustrated graphically for various material parameters. The effects of the pertinent parameters on the local skin friction coefficient, plate couple stress and the heat transfer are also calculated. It was shown that large Darcy parameter leads to decrease the velocity while it increases the angular velocity as well as temperature of the micropolar fluids. The rate of heat transfer in weakly concentrated micropolar fluids is higher than strongly concentrated micropolar fluids.

Abstract
Glomerulonephritis (GN) is one of the commonest causes of chronic renal failure (CRF) and end stage renal failure (ESRF). The outcome largely depends on the underlying medical cause, clinical findings and histological appearance. 1188 patients were taken in this study. Of these, 980 had primary and 208 secondary GN. Commonest histological types of primary GN were mesangial proliferative glomerulonephritis (31%) and membranous nephropathy (21%). Among patients with secondary GN, predominant cause was lupus nephritis (76%) followed by poststreptococcal GN (18%). Clinically, nephrotic syndrome was present in 54%, hypertension in 39% and renal failure in 28%. But clinical pictures were variable among different histological types of GN.

Abstract
Fine needle aspiration cytology is a widely practiced technique in the diagnosis of breast carcinoma and it is the only, diagnostic procedure performed before definitive treatment, at most institutions. While the histological grading of Duct Cell Carcinoma (DCC), NOS is done routinely in many centers worldwide the cytopathological grading of DCC, NOS is not commonly done. Grading of breast carcinoma, while the tumour is still in vivo, would be the most ideal and desirable situation, as it would be helpful in the selection of appropriate therapy for the patient. This study was undertaken with the aim to determine the grade of DCC, NOS by simple cytological scoring system as a method of predicting histological grade. We selected 80 cases of DCC, NOS which were initially diagnosed by Fine Needle Aspiration Cytology (FNAC) with subsequent histological confirmation. For cytological grading Papanicolou's stained smears and for histological grading Haematoxylin and Eosin stained sections were examined under light microscope. For histological grading Scraff Bloom Richardson's grading and for cytological grading Robinson's grading were followed. In both system grading were grade I, grade II and grade III of DCC, NOS. On cytological grading 39 (48.8%) cases were grade-I, 38 (47.5%) cases were grade-II and 3 (3.8%) cases were grade-III. On histological grading 33 (41.3%) cases were grade-I, 39 (48.8%) cases were grade-II and 8 (10%) cases were grade-III. In this study cytological grade correlated with histological grade in 69 (86.3%) cases. For grade-I tumour, sensitivity was 96.96%, efficiency was 94%. For grade-II tumour the sensitivity was 87.18% and efficiency was 77%. For grade-III tumour the sensitivity was 37.50% and efficiency was 23%. The overall accuracy was 96.3%. Significant association between histological and cytological grading of breast carcinoma, NOS was noted. Our observations in this study revealed that grading of duct cell carcinoma, NOS on FNAC material can be a useful in preoperative assessment of DCC, NOS prognosis and can be useful as an alternative to histological grading when neoadjuvant therapy is planned.

Abstract
Assessment of neural biocompatibility requires that materials be tested with exposure in neural fluids. Laser bonded microjoint samples made from Ti coated glass substrate and polyimide film (GPI) and titanium foil and polyimide film (TIPI) were evaluated for mechanical performance before and after exposure in artificial cerebrospinal fluid (CSF) for two, four, and 12 weeks at 37 degrees C. These samples represent a critical feature, i.e., the microjoint-a major weakness in the bioencapsulation system. Both material systems showed initial degradation up to 4 weeks which then stabilized afterwards and retained similar strength until 12 weeks. The TIPI system appears to exhibit better overall performance with less degradation compared to its as-received strength. The CSF exposed TIPI samples predominantly failed at the interface, while GPI samples had mixed glass and polyimide substrate and interface failure. The amount of glass failure decreases and interface failure increases with increase in CSF exposure time. The failure mechanism of the as-received (not exposed to CSF) GPI samples under tension was predominantly flexure type failure of the glass substrate.

Abstract
Interleukin-1alpha (IL-1alpha) is a proinflammatory cytokine that has also been found to act as a paracrine mediator involved in the regulation of testicular functions. The present review provides an overview of the role of IL-1alpha in testicular physiology. Bioactive IL-1alpha isolated from adult rat testis was found to consist of three distinct immunoreactive protein species with apparent sizes of 45, 24 and 19 kDa. These isoforms showed bioactivity in a thymocyte proliferation and steroidogenesis assays with different biopotencies. The background of the molecular heterogeneity and processing, secretion and regulation of the isoforms of testicular IL-1alpha are discussed. All three isoforms have been found to be secreted into the testis tubular lumen and interstitial space. We have provided evidence that IL-1alpha is a paracrine factor that may be of importance in, e.g., the regulation of Leydig cell steroidogenesis. Pathophysiologically, testicular IL-1alpha may contribute to testicular relapse of acute lymphocytic leukemia in boys.

Abstract
Interleukin-1alpha (IL-1alpha) plays an important role(s) in the regulation of immune and inflammatory responses. The testis is an immunologically privileged organ and the variety of effects exerted by IL-1alpha on this organ have yet to be explored in detail. The aim of the present review is to describe our current view of the paracrine role played by IL-1alpha in testicular physiology. Testicular IL-1alpha is expressed during development, primarily in Sertoli cells, appearing in rats for the first time 20 days after birth. This cytokine is microheterogeneous, consisting of three molecular species with molecular weights of 45, 24 and 17 KDa. The 17 KDa form represents mature IL-1alpha, while the 24-KDa IL-1alpha has been shown by our research group to be an alternately spliced form of the 45-KDa pro-IL-1alpha. IL-1alpha was observed to stimulate the proliferation of immature Sertoli cells with higher efficacy than FSH. IL-1alpha was also found to exert mitogenic effects both on isolated peritubular cells and germ cells. Furthermore, isoforms of IL-1alpha were seen to stimulate basal testosterone production in immature Leydig cells, but not in the corresponding adult cells. This effect involved induction of the steroidogenic acute regulatory (StAR) protein and positively regulation by p38 MAPK. Recently, we have observed positive interactions between IL-1alpha and hormones of the GH/IGF-I system that lead to enhanced androgen production by the Leydig cell. In conclusion, our findings suggest that isoforms of IL-1alpha may serve as paracrine mediators, alone or in concert with other factors, that support proper testicular cell functioning and, thereby, reproduction and fertility.

Abstract
OBJECTIVE To confirm alpha-1-AT deficiency status in duodenal ulcer using a combination of PCR and restricted enzyme digestion. METHODS Fifty patients with endoscopically proven duodenal ulcer and hundred controls with no signs of the disease were included. Alpha-1-AT phenotypes were confirmed by polymerase chain reaction followed by restriction enzyme digestion. RESULTS Alpha-1-AT concentration in duodenal ulcer patients showed a mean value of 2.12 +/- 0.11 g/l (range: 0.52-3.95 g/l, p < 0.05). In controls this was 2.47 +/- 0.08 g/l (range: 0.52-5.0 g/l). Among the controls 70% had the MM phenotype, 28% M1 M2 and 2% FM. In duodenal ulcer, MM predominates (70%), followed by M1 M2 (18%), SS (4%), SZ (4%), ZZ (2%) and MZ (2%). CONCLUSION Alpha-1 AT deficiency was found in 10% of duodenal ulcer patients. DNA analysis more accurately resolved the phenotypes as S and Z mutations.

Abstract
Different isoforms of testicular interleukin-1 (IL-1) were analysed to determine whether there were differences in the ability to modulate rat Leydig cell steroidogenesis in vitro. Rat 17K IL-1alpha and IL-1beta, 32K IL-1alpha precursor (32proIL-1alpha) and a 24K splice variant (24proIL-1alpha) stimulated testosterone production by Leydig cells from 40- but not 80-day-old rats. The potency of the isoforms was IL-1alpha>IL-1beta>32proIL-1alpha>24proIL-1alpha, IL-1alpha being 50-fold more potent than IL-1beta. IL-1 receptor antagonist reversed the effects and IL-1 receptor type I mRNA was expressed by the responding Leydig cells, indicating a receptor mediated action. Inhibition of PKA and Ca(2+) channels abolished IL-1-induced steroidogenesis, while inhibition of PKC had no significant effect. Except for 24proIL-1alpha which was stimulatory, all IL-1 isoforms suppressed hCG-driven testosterone production. This inhibitory effect was abolished by androstendione, suggesting that P450c17 was suppressed by IL-1. Our results indicate that IL-1 plays a paracrine role in the regulation of Leydig cell steroidogenesis.

Abstract
Interleukin-1 (IL-1), a multifunctional cytokine produced mainly by activated macrophages, is also produced in the intact testis. Rat testicular IL-1 was found to be identical to IL-1alpha, judged by immunoneutralization of the bioactive protein and sequence comparison of cloned rat testicular and macrophage pro-IL-1alpha cDNA. Testicular IL-1alpha mRNA was first demonstrated on postnatal day 15, and the corresponding bioactive protein from day 20. IL-1alpha mRNA was still low on day 20, but then increased rapidly in parallel with the bioactive protein to establish a plateau level from day 25. In adult testes, IL-1alpha mRNA and immunoreactive protein were low in stage VII of the seminiferous epithelial cycle, whereas other stages showed a clearly detectable expression. In the adult testis, the concentration of IL-1alpha was 75 pg/mg testicular protein (approximately 200 pM). In conclusion, production of testicular IL-1alpha is developmentally and stage-dependently regulated, probably at the transcriptional level, emphasizing an important paracrine role in testicular function.

Abstract
We report here the characterization of an alternative splice variant of prointerleukin-1alpha (proIL-1alpha), constitutively expressed by the normal adult rat testis. In addition to the classical 32K proIL-1alpha (32proIL-1alpha) messenger RNA, the testis produced a shorter variant encoding a putative protein of 24K (24proIL-1alpha). In situ hybridization demonstrated constitutive expression of the splice transcript in the seminiferous tubules. This alternative complementary DNA lacked the fifth exon, harboring the calpain cleavage site essential for generation of mature 17K IL-1alpha. This was verified by calpain treatment, producing the expected cleavage products of recombinant 32proIL-1alpha, but not of 24proIL-1alpha. Similarly, expression in COS-7 cells demonstrated processing of 32proIL-1alpha to the mature 17K form and secretion, whereas 24proIL-1alpha remained unprocessed. Both 32proIL-1alpha and 24proIL-1alpha showed a dose-dependent stimulatory effect in a thymocyte proliferation assay, although at lower potency than mature 17K IL-1alpha. In contrast, when tested on hCG-stimulated Leydig cells in vitro, a dose-dependent inhibition of testosterone production was obtained with mature 17K IL-1alpha and at a lower potency with 32proIL-1alpha, whereas 24proIL-1alpha was inactive. In conclusion, the three IL-1 bioactive proteins described here contribute to IL-1 protein heterogeneity and may serve as constitutive paracrine mediators in the testis.

Abstract
The interleukin-1 (IL-1) family consists of two agonist proteins, IL-1 alpha and IL-1 beta, and one antagonist, IL-1 receptor antagonist (IL-1ra), which blocks the action of the agonists by binding and competing at the IL-1 receptor level. IL-1 beta and to a lesser extent IL-1 alpha were originally described as rapidly inducible proinflammatory cytokines released by activated macrophages. However, IL-1 alpha has been found to be constitutively produced by certain tissues, and noninflammatory functions have been proposed for this protein, although they have not yet been well elucidated. Consistent with this suggestion, we previously showed that the intact rat testis constitutively produces large amounts of IL-1 alpha at both the mRNA and protein levels. The expression of IL-1 alpha was found to be confined to Sertoli cells, with evidence of a developmental as well as a stage-dependent production pattern. In more recent studies, we have found indications that the testis can also initiate production of IL-1 beta upon stimulation with inflammatory inducers such as endotoxin. Further, we have detected constitutive testicular expression of IL-1ra, opening up the possibility that IL-1 action in the testis may be specifically regulated by paracrine mechanisms. Recent data have demonstrated that the testis can produce more than one isoform of IL-1 alpha with indications of both post-transcriptional and post-translational modifications, resulting in at least three distinct bio- and immunoreactive IL-1 alpha proteins. We conclude that all three classical IL-1 ligands and novel IL-1 alpha isoforms are present in the testis and may serve as paracrine mediators under physiological or pathophysiological conditions. The function of this testicular IL-1 agonist-antagonist network is a current focus of investigation.

Abstract
Knowledge of the essential characteristics of macromolecules constituting the organic matrix of the nidus of urinary stones is required to understand the mechanism of urolithogenesis. The aim of this study was to isolate and characterise those stone nidus proteins. Using an extraction buffer containing SDS and beta-mercaptoethanol, we were able to overcome known problems of protein isolation from urinary stone matrix. These proteins were characterised by a strong tendency to aggregate under reducing and denaturing conditions. On SDS-PAGE, their molecular weights range from < or = 12 to 66 kDa. Antisera raised against stone matrix proteins showed a cross-reactivity between proteins isolated from different stones irrespective of their origin or mineral composition. Moreover, urinary proteins from stone formers also cross-reacted with these whereas there was no reaction with urinary proteins of non-stone formers. Western blotting confirmed these findings. Given the above summarised properties, it can be safely concluded that these proteins are prevalent in urines of stone formers, that they are selectively incorporated into renal stones of all aetiologies, and that they most likely have a role in nidus and, therefore, early stone formation.

Abstract
The rate of transmission and management of needlestick injuries from hepatitis C virus (HCV) patients to healthcare workers is still a matter of debate. We used a stringent protocol using monthly transaminase levels and polymerase chain reaction for HCV RNA to monitor 53 healthcare workers prospectively for up to 6 months following needle injuries from HCV-positive patients. Evidence of transmission of HCV was found in only 2 workers (4%) with mild asymptomatic infection, one of which resolved spontaneously. Based on our experience, we now use a less-intensive follow-up protocol. Further investigation is required to determine the most cost-effective method to monitor individuals who suffer a needlestick injury from an HCV-positive patient.

Abstract
The application of ultraviolet light (UV-C, 254 nm) hormesis on fruits and vegetables to stimulate beneficial responses is a new method for controlling storage rots and extending the shelf-life of fruits and vegetables. The present study was aimed at treating tomatoes ( Lycopersicon esculentum ) with different UV-C dosages (1.3 to 40 KJ/m2) to induce resistance to black mold ( Alternaria alternata ), gray mold ( Botrytis cinerea ), and Rhizopus soft rot ( Rhizopus stolonifer ). These diseases were effectively reduced when tomatoes were inoculated following UV-C irradiation. UV-C treated tomatoes were firmer in texture and less red in color than the control tomatoes, indicating a delay in ripening. Slower ripening and resistance to storage rots of tomatoes are probably related. The positive effect of UV-C on tomatoes decreased as treatments were performed at stages of increased ripeness.
