Abstract
The genus Allium comprises of at least 918 species; the majority grown for dietary and medicinal purposes. This review describes the traditional uses, phytoconstituents, anti-inflammatory and anticancer activity, and safety profile of six main species, namely Allium sativum L. (garlic), Allium cepa L. (onions), Allium ampeloprasum L. (leek), Allium fistulosum L. (scallion), Allium schoenoprasum L. (chives) and Allium tuberosum Rottler (garlic chives). These species contain at least 260 phytoconstituents; mainly volatile compounds-including 63 organosulfur molecules-, saponins, flavonoids, anthocyanins, phenolic compounds, amino acids, organic acids, fatty acids, steroids, vitamins and nucleosides. They have prominent in vitro anti-inflammatory activity, and in vivo replications of such results have been achieved for all except for A. schoenoprasum. They also exert cytotoxicity against different cancer cell lines. Several anticancer phytoconstituents have been characterized from all except for A. fistulosum. Organosulfur constituents, saponins and flavonoid glycosides have demonstrated anti-inflammatory and anticancer activity. Extensive work has been conducted mainly on the anti-inflammatory and anticancer activity of A. sativum and A. cepa. The presence of anti-inflammatory and anticancer constituents in these two species suggests that similar bioactive constituents could be found in other species. This provides future avenues for identifying new Allium-derived anti-inflammatory and anticancer agents.

Abstract
Atherosclerosis is the pathognomic sign of ischaemic heart disease. Inflammation of the coronary artery contributes to the development of atherosclerosis. Neutrophil-to-lymphocyte ratio (NLR) has been reported to predict the risk of CAD and associated events in patients with ST-Segment elevation myocardial infarction (STEMI). This study was done to investigate the role of neutrophil-to-lymphocyte ratio (NLR) in predicting in-hospital adverse cardiac events in patients with STEMI thrombolysed with streptokinase (STK). This cross sectional descriptive type of study was conducted in the Department of Cardiology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from August, 2017 to October, 2018. The STEMI patients, thrombolysed with STK had blood samples at admission, analyzed for complete blood counts and NLR calculated. They were grouped into two, low and high NLR, taking 4.50 as cut-off value. Chi square test was used to compare rate of adverse events and death in hospital stay. Logistic regression analysis was used to estimate predictive ability of NLR for in-hospital cardiac events. A total of 87 (39.90%) patients had complications. Patients in high NLR group had higher rate of complications (48.3% vs. 22.5%, p<0.001) in hospital than those in low NLR group. Arrhythmias (21.1% vs. 9.9%, p<0.041), heart failure (27.9% vs. 14.1%, p=0.024), cardiogenic shock (16.3% vs. 4.2%, p<0.011), death (6.8% vs. 2.8%, p=0.227), re-infarction /post MI angina (4.1% vs. 0.0% p=0.084) occurred more in high NLR group. Mean NLR was significantly different between Group I and Group II (3.11±0.84 vs. 10.20±6.08, p<0.0001). Multivariate regression analysis showed NLR an independent predictor of in-hospital adverse cardiac events (p<0.0001). High on admission NLR is an independent predictor for in-hospital adverse cardiac events in patients with STEMI thrombolysed with streptokinase.

Abstract
The huge numbers of non-healthcare personnel (non-HCP) who get infected by corona virus disease 2019 (COVID-19) not only paralyze health care systems but also put health care personnel (HCP) at potential risk globally. Objective of the study was to compare the Healthcare personnel (HCP) and non-HCP COVID-19 cases. This prospective observational study was carried out in National Heart Foundation Hospital and Research Institute of Bangladesh from March 08, 2020 to July 20, 2020. During this study period all admitted non-HCP who subsequently was diagnosed as COVID-19 positive by rRT-PCR and HCP of this hospital, who experienced fever or respiratory symptoms or came in close contact with COVID-19 patients at home or their workplace and become COVID-19 positive, were included. Out of 320 infected patients, 181(56.6%) patients were non-HCP and 139(43.4%) were HCP. Non-HCP were older than HCP (Mean age: 52.95±13.82 years vs. 34.08±11.11 years; p=0.001). Non-HCP were predominantly male and HCP were predominantly female (73.5% vs. 41% & 26.5% vs. 59%; p=0.001). Non-HCP had more risk factors and co-morbidities than HCP (p=0.001). Typical symptoms of COVID-19 such as fever and cough were prevalent in HCP. More aggressive treatment was required for non-HCP. Non-HCP had more severe disease and higher case fatality rate (9.4% vs. 0.7%; p=0.001) than HCP. Disease severity (OR 0.03, 95% CI 0.01-0.15) and DM (OR 0.09, 95% CI 0.01-0.94) were the independent predictor of mortality. Non-HCP was older in age, predominantly male and had more co-morbidities than HCP. Typical symptoms of COVID-19 were prevalent in HCP. Non-HCP had more severe disease and higher case fatality rate than HCP.

Abstract
Organic-inorganic perovskite solar cells (PSCs) have recently emerged as a potential candidate for large-scale and low-cost photovoltaic devices. However, the technology is still susceptible to degradation issues and toxicity concerns due to the presence of lead (Pb). Therefore, investigation on ideal methods to deal with PSC wastes once the device attains its end-of-life is crucial and to recycle the components within the cell is the most cost effective and energy effective method by far. This paper reported on a layer-by-layer extraction approach to recycle the fluorine-doped tin oxide (FTO) coated glass substrate which is the most expensive component in the device architecture of mesoporous planar PSC. By adapting the sequential removal of each layer, chemical properties of individual components, including spiro-OMeTAD and gold can be preserved, enabling the material to be easily reused. It also ensured that the toxic Pb component could be isolated without contaminating other materials. The removal of all individual layers allows the retrieval of FTO conductive glass which can be used in various applications that are not only restricted to photovoltaics. Comparison of electrical, morphological and physical properties of recycled FTO glasses to commercial ones revealed minimal variations. This confirmed that the recycling approach was useful in retrieving the substrate without affecting its physicochemical properties.

Abstract
Most of the mortalities among Diabetic Nephropathy patients are cardiovascular, if we identify the risk factor, measures can be taken to prevent it. Hence an objective was set to evaluate the association between carotid artery intima media thickness (CIMT) with eGFR in patients of CKD stage III, IV and V among patients with type 2 diabetes mellitus; also, correlation with age, BMI, lipid profile. This cross-sectional, observational study was performed in 70 patients in different stages of CKD in Diabetic Patients selected by Inclusion Criteria (Diabetic nephropathy patients with stages III, IV, V and exclusion Criteria (Acute kidney injury, History of carotid surgery, Patients of MI and stroke). This study was performed in Department of Nephrology, Dhaka Medical College in collaboration with the Department of Radiology and Imaging, laboratory of Department of Biochemistry and Department of Microbiology at Dhaka Medical College Hospital (By standard method in laboratory) from 1st January 2016 to 31st December 2016. eGFR was measured by MDRD formula and the CIMT was measured using an ultrasonographic examination. The mean CIMT was 0.9±0.21mm, and 62.9% of the subjects showed IMT thickening (≥1mm). The carotid IMT elevated significantly with the stage progression of CKD (Overall eGFR mean 28.8±14.5mL/min/1.73m² in CIMT<1mm with range from 6 to 54 and 9.1±9.0mL/min/1.73m² in CIMT ≥1mm with range from 3 to 32 (p=0.001). The eGFR was significantly lower in the patients with CIMT thickening than those without CIMT thickening. eGFR was also significantly associated with CKD stages (p=0.001), serum creatinine (p=0.001), BMI (r = -0.330, p=0.005), and negatively associated with age group, duration of hypertension, smoking. However, the CIMT was not significantly different among the patients at different stages of diabetic nephropathy (r = -0.172, p=156) and age group. It has been concluded that the mean CIMT was markedly high in patients with CKD compared to normal expected value. This study showed a relationship between the CIMT and the renal parameters as eGFR and the stages of diabetic nephropathy with a confirm association between the CIMT and diabetic macroangiopathy.

Abstract
Heart failure is a major public health issue with a current prevalence of over 23 million worldwide. Epidemiologic studies suggest that nearly one-half of patients with heart failure have a normal ejection fraction that is now termed HFpEF. Prevalence of HFpEF is approximately 50% (range 40-71%). Most pathophysiologic abnormalities in patients with HFpEF are related to diastolic function. Doppler echocardiography is the choice of investigation for evaluation of Diastolic function. Tissue Doppler Imaging is a new dimension in this concept. Natriuretitic peptides are widely accepted biomarker in HFrEF patients. Now a days, it is also considered for HFpEF patients for diagnostic & prognostic purpose. Aim of this study was to find out the association of Diastolic dysfunction with N-terminal Pro B-type Natriuretic Peptide level in HFpEF patients. This cross-sectional analytical study was conducted in the department of Cardiology in Mymensingh Medical College Hospital, Mymensingh, Bangladesh from October 2016 to September 2017. Total 120 HFpEF patients were included after considering inclusion and exclusion criteria. Sample population was divided into two groups, Group I: HFpEF patients with normal Diastolic function. Group II: HFpEF patients with diastolic dysfunction in this study mean NT-pro BNP value of Group I and Group II were 104.07±7.2pg/ml and 943.19±112.51pg/ml respectively, which was statistically significant (p value <0.05). Among the echocardiographic parameters LV hypertrophy, Left atrial volume index (LAVI), TDI derived mitral annular velocity, e' septal velocity, E/e' (septal) ratio, Decelaration time were statistically significant. In this study, it was also shown that the levels of NT-proBNP had positive correlation with Doppler parameters. Statistically significant moderate positive correlation was observed between NT-proBNP level and LAVI value, correlation coefficient (r=0.553, p=0.001) suggesting that the higher the level of NT Pro BNP level, the higher value of the LAVI value. Statistically significant moderate positive correlation was also observed between NT-proBNP level and E/e' (septal), correlation coefficient (r=0.526, p=0.001) suggesting that the higher the level of NT Pro BNP level, the Higher value of the E/e' (septal) value in HFpEF patients with diastolic dysfunction. In subgroup analysis of Group II ,mean NT-proBNP level showed affirmative relation with severity of diastolic dysfunction grades ranging from grade I (340.76±24.42) to grade III (3727.83±306.50) Diastolic dysfunction is associated with elevated NT-proBNP level in HFpEF patients & NT-proBNP value rises with gradual deterioration of Diastolic dysfunction among the HFpEF patients.

Abstract
Globus sensation is a subjective feeling of a lump or foreign body in the throat without interfering swallowing of food. It is a persistent and distressing sensation in throat. It affects about 6% of population. But cause of globus is still unknown. Exact aetiology of globus is considered to be multifactorial. Some other studies also show association between globus and psychological distress including anxiety and depression. As there is no established pharmacological treatment, adequate investigations with negative result could reassure patients and improve their symptoms. In this prospective study consecutive patients with globus symptoms examined by upper GIT endoscopy with attention to larynx, epiglottis, base of tongue, both pyriform fossa and hypo-pharynx using Olympus forward viewing video Gastroscope (GIF Q-150 & GIF Q-170) to exclude organic lesion and was conducted in the department of Gastroenterology, Bangabandhu Sheikh Mujib Medical University (BSMMU) and North East Medical College, Sylhet from 1st July 2014 to 31 December 2016. Their psychological status and epidemiological information including personal and family history were noted in a pre-designed data sheet. Total 104 patients were examined, among them definite anxiety was found in 36(34.95%) and borderline feature of anxiety was found in 19(18.44%) and 48(46.60%) were free of anxiety. Incidence of anxiety was significantly higher among females and was more prevalent among housewife, married people and people from rural community. In this series, 13(12.5%) patients had definite depression and 29(27.9%) patients had borderline depression, while 61(59.2%) patients had no feature of depression. Incidence of depression was significantly higher among females, housewife and married people. Organic lesion is rare in patients with globus symptoms. Globus sensation is more common among females. Psychological factors like anxiety and depression are frequently associated with globus sensation.

Abstract
This cross sectional descriptive study was performed on 70 postmortem vermiform appendix (male 34 and female 36) to find out the external diameter of vermiform appendix of Bangladeshi people in different age and sex. The specimens were collected from autopsy laboratory of the Department of Forensic Medicine, Mymensingh Medical College, Mymensingh, Bangladesh from October 2016 to March 2017 by purposive sampling technique. The collected samples were divided into four age groups. They were Group A (upto 20 years), Group B (21 to 40 years), Group C (41 to 60 years) and Group D (above 60 years). Dissection was performed according to standard autopsy techniques. The vermiform appendix was collected and preserved in 10% formol-saline solution. The external diameter of vermiform appendix was measured with the help of digital slide calipers. Three measurements were taken at its base, middle and near the tip (1cm away from the tip) and expressed in mm. The data were analyzed by using student unpaired 't' test and compaired with the findings of other national and international studies and standard text books. It was observed that external diameter of vermiform appendix gradually decreased as age advanced. The mean±SD external diameter of vermiform appendix at base was 6.50±0.82 mm, 6.22±0.60 mm, 6.00±0.51 mm and 5.51±0.57 mm in Group A, B, C & D respectively. The mean±SD external diameter of vermiform appendix at middle was 6.09±0.89 mm, 5.67±0.65 mm, 5.38±0.59 mm and 4.95±0.76 mm in Group A, B, C and D respectively. The mean±SD external diameter of vermiform appendix near the tip (1 cm away from the tip) was 5.73±0.88 mm, 5.21±0.72 mm, 4.81±0.74 mm and 4.34±0.74 mm in Group A, B, C and D respectively. Statistical analysis shows that the mean differences of external diameter of vermiform appendix at its base between Group A&D, B&D were statistically moderately significant at p<0.01 level. Between Group C&D was statistically significant at p<0.05 level and between Group A&B, B&C, A&C were statistically non significant at p = or >0.05 level. Mean differences of external diameter of vermiform appendix at its middle between Group A&D, B&D were statistically moderately significant at p<0.01 level. Between Group A&C was statistically significant at p<0.05 level and between Group A&B, B&C, C&D were statistically non significant at p = or >0.05 level. Mean differences of external diameter of vermiform appendix near its tip (1 cm away from the tip) between Group A&D was statistically highly significant at p<0.001 and mean differences between Group B&D, A&C were statistically moderately significant at p<0.01 level. Between Group A&B was statistically significant at p<0.05 level and between Group B&C, C&D were statistically non significant at p = or >0.05 level. Mean external diameter of vermiform appendix in male was higher than that of female in all age group at its base, middle and near the tip (1cm away from the tip) but mean difference between sexes in the different study groups was statistically non significant at p = or >0.05 level. The present study will help to increase the information pool on the external diameter of vermiform appendix of Bangladeshi people.

Abstract
An experimental study was carried out to evaluate the effect of Captopril on Gentamicin induced nephrotoxicity in rats in the Department of Pharmacology, Mymensingh Medical College and Dhaka Medical College, Bangladesh. Gentamicin antibiotic is most commonly employed clinically because of their potent bactericidal activities against Gram negative bacterial infections, less bacterial resistance, post-antibiotic effects and low cost. Gentamicin is associated with an induction of slow rises in serum creatinine, inflammation and perivascular edema, tubular degeneration and necrosis, tubular debris collection, glomerular atrophy which ultimately show the way to renal dysfunction. In spite of continued attractive efforts during the last decade, antioxidants like medicinal plants and different classes of drugs which were promised to reduce or ameliorate Gentamicin induced nephrotoxicity is yet a matter of debate. This study was aimed at inducing nephrotoxicity by injection Gentamicin and estimating the renal damage biochemically by measuring serum creatinine and perform histopathology of renal cortex in support of biochemical findings both in control groups, nephrotoxic and Captopril treated rats; also to determine the comparison between the concomitant and post effects of Captopril on control and nephrotoxic rats and to estimate the effect of Gentamicin withdrawal, 7 days after last injection in rats.

Abstract
Hepatitis B virus (HBV) infection is a major public health problem in the world. About 30% of world population has serological evidence of HBV infection. The prevalence of chronic hepatitis B in Bangladesh is reported to be 7.8%. Several potentially effective agents with different mechanisms of action have entered clinical practice and adefovir dipivoxil is one of them. Studies on the efficacy of adefovir dipivoxil in Bangladeshi patients are lacking. This was a prospective study to find out the effect of one year adefovir therapy in patients with chronic hepatitis B virus infection who were HBeAg positive. Total number of patients included in this study was 68. Among them 53(77.94%) patients continued the therapy and completed follow up. At the end of one year of therapy, intention to treat analysis showed that the rate of response (HBeAg seroconversion and HBV DNA negative) was 37.73% which was comparable to the results obtained in other studies. There was major difference in the pre treatment serum ALT level between the responders and non-responders. Comparison of reduction of serum ALT level before treatment and after treatment showed that ALT level to be lower in both responder group and non responder group. Adefovir was effective in replicative HBV infection in Bangladeshi population. So we suggest that treatment can be started and subsequent follow up can be done in chronic HBV patients who are HBeAg positive without liver biopsy.

Abstract
Ulcerative colitis may involve anywhere from the rectum alone to the entire colon. Local complications like perforation, life threatening haemorrhage, toxic megacolon, pseudo polyps, stricture, and carcinoma of colon are seen. Patients who were diagnosed as Ulcerative Colitis in Departmental Ulcerative Colitis record book from January 1990 to June 2010 was considered as study population. Information regarding the extent of the disease and local complications were taken from earliest documented Lower GIT Endoscopy. Out of 164 patients disease extent were seen in 126(76.83%) patients and among them proctitis/proctosigmoiditis were seen in 57(45.24%) patients, left sided colitis were seen in 11(8.73%) patients, extensive/pan colitis were seen in 58(46.03%) patients. Complication were seen in 164 patients and 1(0.60%) patient had life threatening haemorrhage, 25(15.24%) patients developed pseudo polyps. There was no report of perforation, toxic megacolon, stricture or carcinoma of colon. The differences found between our study and studies from other Western and Asian countries in terms of complication rate and disease extent for were probably due to low index of suspicion, incomplete workup, or incomplete records, and influence of various environmental factors. So, further large scale prospective evaluation is suggested.

Abstract
Crush smear cytology, commonly used for central nervous system lesions was reported to be useful in the diagnosis of GI malignancies. This study was designed to see the accuracy of crush smear cytology in detection of gastrointestinal malignancy in relation to histopathological examination. First 4 or 5 bits of pinch biopsy specimens from each of the consecutive patients having endoscopic findings suggestive of carcinoma of gastro-intestinal tract were examined by conventional paraffin embedding and H-E staining by a cytologist. Crush smears stained with Papanicolaou's stain were prepared with the last bit of specimen and were examined by another cytologist. The diagnostic accuracy was examined by correlating with clinical and histological data. Out of 100 cases of suspected oesophageal malignancies, 99 were diagnosed as carcinoma by histopathology and 84 (sensitivity 83.83%, accuracy 83%, K - 0.14) cases were positive for malignancy by crush smear cytology. Out of 60 cases of gastric lesion, 54 and 44 cases were proved to be malignant by histopathology (sensitivity 76%, accuracy 73.3%, K - 0.2) and crush smear cytology respectively. Fifty four of the 57 cases of colonic lesions were proved to be malignant by histopathology and 50 (sensitivity 91%, accuracy 89.5%, K - 0.34) were malignant by crush smear cytology. Combining two methods the accuracy was 100%, 95% and 96.5% in detecting oesophageal, gastric and colonic malignancies respectively. Concordance rate of both the methods in diagnosing oesophageal, gastric and colonic lesions were 883.83%, 73.3% and 89.5% respectively. Crush smear cytology is a cheap, easy and rapidly performing technique. The diagnostic yield is very high when the technique is combined with histopathology. It may be used as a useful adjunct to conventional histopathology.

Peginterferon α-2a with ribavirin produces significantly higher sustained virological response (SVR) in comparison to conventional interferon monotherapy in patients with chronic hepatitis C virus (HCV) infection. We evaluated the efficacy and safety of peginterferon α-2a plus ribavirin combination in the treatment of chronic hepatitis C among Bangladeshi patients. A total of 64 patients were randomly selected in this study and were assigned for treatment with peginterferon α-2a 180μg once weekly plus ribavirin daily for 24 weeks in case of genotypes 2 and 3 infections and 48 weeks in case of genotypes 1 and 4 infections. Ribavirin was given 800mg in divided doses in case of genotypes 2 and 3 infections and 1000mg-1200 mg in case of genotypes 1 and 4 infections according to body weight daily(1000 mg in divided doses if body weight <75kg and 1200mg in divided doses if body weight >75kg). Efficacy was assessed by measurements of serum HCV-RNA and serum ALT. A higher proportion of patients (71.87%) who received peginterferon α-2a plus ribavirin had a sustained virological response. It is observed that genotype 3 (a and b) patients showed poor response (SVR-47.05%), where as genotypes 1(a,b), 3 and 4 mixed, 2b and 4 infections showed response rate of 100%. So it can be concluded that once weekly peginterferon α-2a plus daily ribavirin is effective in chronic HCV infection in Bangladesh and overall response rate is similar to that reported in other studies.

Abstract
Chronic hepatitis B virus (HBV) is known to be the significant cause of Liver related morbidity and mortality, affecting 400 million people worldwide and a major public health problem in Bangladesh where carrier rates of HBV infection varies from 7.5 to 10%. In Bangladesh prevalence of asymptomatic HBV infection and incidentally detected HBsAg positive subjects were not well studied. The aim of this study is to evaluate the disease activity, replicative status of the virus and to find out the stages of chronic liver disease among incidentally detected asymptomatic HBsAg positive Bangladeshi subjects. Two hundred (200) incidentally detected healthy HBsAg positive subject were evaluated clinically, biochemically, serologically and ultrasonographically from January 2004 to June 2008. HBeAg was found positive in 17(8.5%), anti-HBe was positive in 174(87%), raised serum ALT (>45iu/L) in 45(22.5%), prothrombine time (PT) >3 sec of control in 33(16.5%). Ultrasonography showed coarse hepatic echotexture in 13(6.5%). Evidence of active viral replication and signs of chronic liver disease were observed among incidentally detected healthy HBsAg positive subjects. Such individuals should be followed up at regular interval to evaluate the replicative status of the virus and disease activity so that appropriate measures could be initiated in time.

Abstract
Irritable bowel syndrome (IBS) is a functional disorder characterized by chronic or recurrent abdominal pain or discomfort with bowel disturbances. This prospective, randomized clinical trial has been conducted on IBS patients, using trimebutine and Mebeverine in separate group in parallel design to compare the efficacy and safety of Trimebutine 100mg twice daily with mebeverine 135mg twice daily. Patients of 15 to 60 years old and both sexes were included from the out patient department (OPD) of gastroenterology, Bangabandhu Sheikh Mujib Medical University (BSMMU) from June 2010 to December 2011. A validated IBS-QOL instrument consisted of 34 questions used to assess improvement of quality of life before and after treatment. A total of 140 patients were enrolled in this study. Eighteen patients dropped out. One hundred twenty two patients completed the trial. In this study at the end of 6 weeks therapy, improvement of symptoms was statistically significant. However, differences of improvement between the two groups in relieving various symptoms were not statistically significant. Mean QOL score before treatment was 103 in Trimebutine group and 106 in Mebeverine group. After 6 weeks of treatment mean QOL score was 82 in Trimebutine group and 95 in Mebeverine group indicating improvement in both groups was statistically significant. The difference between the two groups was also significant. No worsening of symptoms and no side effects of the therapeutic agents was observed in any patient during the trial.

Abstract
Peginterferon alpha-2a and ribavirin combination therapy achieves a sustained virological response (SVR) in patients with chronic hepatitis C. Little is know about long-term durability of hepatitis C virus--Ribonucleic acid (HCV-RNA) negativity in patient treated with pegylated interferon and ribavirin therapy. Aim of this study was to evaluate the durability of virologic response in patients with SVR to anti-viral therapy treated at our centre. A total of 52 patients with chronic hepatitis C virus infection who had obtained SVR after Peginterferon alpha-2a and ribavirin combination therapy were followed up to 5 years with annual HCV-RNA testing. During this follow up period, 4 of 52 patients with initial SVR developed late relapse of hepatitis C virus infection. Relapse was more common in patients who has cirrhosis (3/6 [50%]) vs (1/46 [2.17%]) without cirrhosis. In conclusion, SVR is durable in most patients, but some patients do have late relapse; long-term follow up may be particularly important in a subset of patients with hepatitis C virus infection who have liver cirrhosis.

Abstract
Beach Sand Exploitation Centre at Cox's Bazar, Bangladesh, produces commercial grade concentrations of magnetite, ilmenite, zircon, etc., from the high-grade accumulations available along the beach and foredune of Cox's Bazar. Solid state nuclear track detectors (CR-39 foils) were used to determine indoor radon concentration of radioactive mineral sands and the technologically enhanced radiation level inside the pilot plant of the Centre. It is found that the concentrations at processed mineral stock areas are high, and the maximum concentration was found to be 2,103 +/- 331 Bq m(-3) (0.23 +/- 0.03 WL). The indoor concentration of radon and its decay products in the raw sand stock area and at other locations was in the range of 116 +/- 27 Bq m(-3) (0.03 +/- 0.003 WL) to 2,042 +/- 233 Bq m(-3) (0.22 +/- 0.03 WL).

Abstract
As part of a large-scale sero-epidemiological survey on visceral leishmaniasis (VL) carried out in Mymensingh district of Bangladesh, applicability of DAT was assessed at the level of a rural health setting in Trishal (upazila) subdistrict. Despite the relatively less optimal conditions encountered, 5854 inhabitants from 7 villages appendant to Trishal were assessed for VL. The demographic distribution for sero-positivity obtained at the rural setting was comparable to that found by DAT as executed at the central laboratory (IEDC&R, Dhaka) on 9619 inhabitants from the same upazila. The overall sero-prevalence rate was 4.4% compared to 3.7% obtained in the population assessed at the central laboratory. In either study, similar VL prevalence rates of 2.1% were obtained in the male populations. Irrespective of sex, younger population (< 20 years) in both studies appeared to have higher VL incidence rate (2.3% and 2.6%) than others of 21- > or = 90 years (1.4% and 1.8%). Local production of DAT antigen employing an authochtonus L. donovani isolate was attempted at the central laboratory (IEDC&R) in Dhaka. By comparison with the reference antigen, titres obtained in all 33 VL sera tested were equally higher (1:6400- > or =: 51200) than in 35 out of 38 negative controls (< or = 1:400-1:1600). A comparable level of reactivity was also obtained in 53 VL and 52 negative control sera using a well characterized L. donovani strain (MHOM/IN/80/D88) from India. However, unlike the reference strain, titres obtained in 7 endemic controls were significantly higher with the authochtonous and homologous antigen (1:3200 - 1:6400) than with the reference (1:100 - 1:1600). The results signify the advantage of employing indigenous L. donovani isolates to further improve DAT sensitivity for detection of early and sub-clinical VL.

Abstract
Control of endemic visceral leishmaniasis (VL) in large communities requires a feasible epidemiological indicator capable of monitoring on-going transmission rather than mere exposure to the parasite. Following confirmation of the desired level of reliability for laboratory diagnosis of VL, the direct agglutination test (DAT) was employed to estimate VL sero-prevalence in the endemic upazilas (subdistricts) of Trishal and Shahjadpur within Mymensingh and Sirajganj districts of Bangladesh. DAT antigen production was duly increased to allow coverage of a study population of 17826 inhabitants, 9619 of whom resided in Trishal, 7328 in Shahjadpur and 879 in Teknaf (Cox's Bazar), a known Leishmania-free district in Bangladesh. Despite large-scale production in batches of 1120-4000 ml (each sufficient for 1176-6400 screening doses), all DAT antigen batches performed as required in quality control tests for sensitivity, specificity and stability. It was convenient for both collection and testing to take the required samples of whole blood by finger prick. A cross-sectional survey revealed VL point prevalences of 4.40% in Trishal and 6.75% in Shahjadpur, compared with an extremely low rate of 0.34% in non-endemic Teknaf. In both endemic upazilas (Trishal and Shahjadpur) VL was more prevalent (2.56-4.5%) in persons up to 20 years of age than in those 21 years of age and older (1.84-2.25%). Of 918 subjects recorded as seropositives, 539 were VL-asymptomatic and 379 were VL-symptomatic with various degrees of suspicion. Diagnosis of VL was established in 125 symptomatic seropositives subjects, either by demonstrating the presence of Leishmania amastigotes (29), or by positive DAT results combined with presentation of typical VL signs (96).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The number of colonies formed by unirradiated Clostridium botulinum 62A spores was independent of temperature, in the range from 20 to 45 degrees C (in 5 degrees C increments); no colonies developed at 50 degrees C. Spores irradiated at 1.2 or 1.4 Mrads produced more macrocolonies at 40 degrees C than at higher or lower temperatures. Apparently, radiation-injured spores were capable of repair of 40 degrees C than at the other temperatures studied. More than 99% of the radiation (1.2 Mrads) survivors were injured and were unable to form macrocolonies in the presence of 5% NaCl. The germinated radiation-injured spores were also sensitive to dilution, resulting in the loss of viability of 77 to 79% of the radiation survivors. At 30 and 40 degrees C, the irradiated spores did not differ significantly in the extent of germination (greater than 99% at both 30 and 40 degrees C), emergence (64% at 30 degrees C and 67% at 40 degrees C), and the maximum number of emerged cells that started to elongate (69% at 30 degrees C and 79% at 40 degrees C). However, elongation was remarkably more extensive at 40 degrees C than at 30 degrees C. Many elongated cells lysed within 48 h at 30 degrees C, indicating an impaired repair mechanism. If the radiation-injured spores were incubated at 40 degrees C in the recovery (repair) medium for 8 to 10 h, they germinated, emerged, and elongated extensively and were capable of repair. If, after 8 to 10 h at 40 degrees C, these cultures were shifted to 30 degrees C, the recovery at 30 increased by more than eightfold, resulting in similar colony counts at 30 and 40 degrees C. Thus, repair appeared to be associated with outgrowth. Repair did not occur in the presence of chloramphenicol at 40 degrees C, whereas penicillin had no effect, suggesting that the repair involved protein synthesis but did not require multiplication.
