Abstract
Byttneria pilosa, a flowering plant from the Malvaceae family traditionally used to treat ailments such as boils and scabies, is here investigated for its potential health benefits. The study focused on evaluating its antioxidant and antidiabetic properties in vitro, as well as the in vivo anxiolytic and antidepressant activities of the methanol extract of B. pilosa leaf (MEBP). The study employed various assays to evaluate antioxidant activity, including 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, reducing power capacity, and quantification of the total phenolic and flavonoid contents of MEBP. Additionally, anxiolytic and antidepressant activities were evaluated through four tests: elevated plus-maze test (EPMT), light-dark box test (LDBT), forced swimming test (FST), and tail suspension test (TST). Antidiabetic effect was determined using α-amylase inhibition assay. Docking analysis was performed using BIOVIA and Schrödinger Maestro (v11.1), and the absorption, distribution, metabolism, and excretion/toxicity (ADME/T) properties of bioactive substances were investigated using a web-based technique. MEBP exhibited moderate antioxidant activity in DPPH radical scavenging and reducing power capacity assays, with a dose-dependent response. The total phenolic and flavonoid contents measured were 70 ± 1.53 mg and 22.33 ± 1.20 mg, respectively. MEBP demonstrated significant effects in α-amylase inhibition comparable to acarbose. In behavioral tests, MEBP dose-dependently altered time spent in open arms/light box and closed arms/dark box, indicating anxiolytic effects. Moreover, MEBP significantly reduced immobility duration in FST and TST, suggesting antidepressant properties. Molecular docking analysis revealed favorable interactions between beta-sitosterol and specific targets, suggesting the potential mediation of anxiolytic and antidiabetic effects. Overall, MEBP exhibits notable anxiolytic and antidepressant properties, along with moderate antioxidant and antidiabetic activities.

Abstract
Marburg virus disease (MVD) caused by the Marburg virus (MARV) generally appears with flu-like symptoms and leads to severe hemorrhagic fever. It spreads via direct contact with infected individuals or animals. Despite being considered to be less threatening in terms of appearances and the number of infected patients, the high fatality rate of this pathogenic virus is a major concern. Until now, no vaccine has been developed to combat this deadly virus. Therefore, vaccination for this virus is necessary to reduce its mortality. Our current investigation focuses on the design and formulation of a multi-epitope vaccine based on the structural proteins of MARV employing immunoinformatics approaches. The screening of potential T-cell and B-cell epitopes from the seven structural proteins of MARV was carried out through specific selection parameters. Afterward, we compiled the shortlisted epitopes by attaching them to an appropriate adjuvant and linkers. Population coverage analysis, conservancy analysis, and MHC cluster analysis of the shortlisted epitopes were satisfactory. Importantly, physicochemical characteristics, human homology assessment, and structure validation of the vaccine construct delineated convenient outcomes. We implemented disulfide bond engineering to stabilize the tertiary or quaternary interactions. Furthermore, stability and physical movements of the vaccine protein were explored using normal-mode analysis. The immune simulation study of the vaccine complexes also exhibited significant results. Additionally, the protein-protein docking and molecular dynamics simulation of the final construct exhibited a higher affinity toward toll-like receptor-4 (TLR4). From simulation trajectories, multiple descriptors, namely, root mean square deviations (rmsd), radius of gyration (Rg), root mean square fluctuations (RMSF), solvent-accessible surface area (SASA), and hydrogen bonds, have been taken into account to demonstrate the inflexible and rigid nature of receptor molecules and the constructed vaccine. Inclusively, our findings suggested the vaccine constructs' ability to regulate promising immune responses against MARV pathogenesis.

Abstract
Background
Macropanax dispermus is traditionally used to treat various diseases by ethnic people. The present research reports the pharmacological properties with phytochemical profiling of the crude extracts of M. dispermus leaves (MDML), its n-hexane (MDHL), carbon tetrachloride (MDTL), chloroform (MDCL), ethyl acetate (MDEL), and aqueous (MDAL) fractions, and crude methanol extracts of its stem barks (MDMS). The in vitro thrombolytic activity was done on human erythrocytes whereas the cytotoxic activity was done by brine shrimp lethality assay. The in vivo analgesic activity was examined by acetic acid-induced writhing, tail immersion, and formalin-induced paw licking method. In contrast, antipyretic activity was done by the brewer’s yeast-induced pyrexia method.
Results
MDHL and MDMS showed 37.05% and 42.21% of significant (p < 0.01) thrombolytic activity, respectively. MDCL and MDMS showed the lower LC50 values of 23.15 and 37.11 µg/ml during cytotoxicity test, respectively. In acetic acid writhing method, MDTL and MDEL showed significant (p < 0.001) inhibition of writhing by 79.34% and 80.17%, respectively. MDMS showed significant (p < 0.001) maximal possible effect (%MPE) of 45.95%, 62.26%, 65.79%, 89.69% and elongation of time in pain reaction of 48.53%, 60.28%, 58.76%, and 70.14% at 30, 60, 90, and 120 min intervals, respectively. MDML at 400 mg/kg exhibited significant (p < 0.001) 82.72% of inhibition of pain at the late phases. MDEL at 400 mg/kg of dose exhibited significant (p < 0.001) reduction of rectal temperature by 36.31%, 62.42%, 89.81%,, and 96.82% at 1, 2, 3, and 4 h intervals, respectively.

Abstract
BACKGROUND COVID-19, a respiratory tract infection caused by SARS-CoV-2, is a burning question worldwide as it gives rise to a pandemic situation. No specific medications are still recommended for COVID-19; however, healthcare support is crucial for ameliorating the disease condition. Pharmacists are the frontline fighters who are responsible for providing healthcare support to the COVID-19 infected patients around the world. This review endeavored to briefly rationalize the contributions of several pharmacy professionals in diverse fields along with their collaborative efforts and dedication regarding their limitations during the COVID-19 situation and view the prospects of pharmaceutical care services in the post-pandemic period. MAIN BODY OF THE ABSTRACT Online databases were utilized to search for scholarly articles and organizational websites, to sum up the information about the contemporary and expanded role of pharmacists. Key articles were retrieved from Google Scholar, PubMed, and Science Direct databases using terms: "COVID-19," "novel coronavirus," "community," "industrial," "hospital," "clinical," "recognition," "obstacles," "collaboration," "SARS-CoV-2," "healthcare," and "outbreak" in combination with "pharmacist." The articles were included from the inception of the pandemic to January 25, 2021. The current review found pharmacist's global contributions and involvements with other professionals to provide healthcare services amidst COVID-19. This included testing of suspects, providing medical information, psycho-social support, debunking myths, mitigating drug shortage events, telemedicine, e-prescription, infection control, and controlling the drug supply chain. In many countries, pharmacists' activities were much appreciated but in some countries, they were not properly acknowledged for their contributions amidst COVID-19 outbreak. They played additional roles such as participating in the antimicrobial stewardship team, improving value-added services, conducting clinical data analysis to suppress the outspread of the SARS-CoV-2. SHORT CONCLUSION During the COVID-19 pandemic while the whole world is fighting against an invisible virus, the pharmacists are the earnest hero to serve their responsibilities along with additional activities. They need to be prepared and collaborate with other healthcare professionals further to meet the challenges of post-pandemic circumstances.

Abstract
BACKGROUND Schizophrenia (SCZ) is an incurable neuropsychiatric disorder generally described by impaired social behavior and altered recognition of reality. For the first time, this study explored serum levels of antioxidants (vitamin A, E, and C), malondialdehyde (MDA), macro-minerals (calcium, potassium, and sodium), and trace elements (zinc, iron, and selenium) in Bangladeshi patients with SCZ and thereby, discovering any pathophysiological correlation. METHODS This case-controlled study evaluated 63 patients with SCZ as cases and 63 healthy individuals as controls. Vitamin A and E levels were defined by RP-HPLC. MDA and vitamin C levels were measured by using UV spectrophotometry, and macro and trace elements by atomic absorption spectroscopy. RESULTS This study found significantly (P ≤ 0.05) elevated MDA levels and decreased levels of antioxidants-vitamin A, C, and E and significantly (P ≤ 0.05) diminished levels of macro and trace elements in cases in contrast to the controls. Serum levels of zinc (Zn), selenium (Se), iron (Fe), potassium (K), calcium (Ca), and sodium (Na) were determined to be 0.33 ± 0.008, 0.0252 ± 0.00060, 0.24 ± 0.01, 64.18 ± 2.72, 36.88 ± 2.56, and 2657.5 ± 53.32 mg/L, respectively, in cases, whereas 0.79 ± 0.03, 0.0650 ± 0.00355,0.78 ± 0.03, 168.01 ± 2.85, 86.43 ± 2.55, and 3200.8 ± 29.96 mg/L, respectively, were determined in controls. Pearson's correlation analysis revealed a negative correlation between Zn and Na, Zn and K, Zn and Ca, Zn and Fe, Zn and Se, Fe and Na, and Fe and Se in patients. CONCLUSIONS The findings connect that the pathogenesis of SCZ may have a correlation with altered levels of antioxidants, MDA, macro-minerals, and trace elements.

Abstract
Natural regeneration is an essential tool to evaluate the overall health of a forest ecosystem. Natural regeneration of the tree species in Madhupur National Park showed 47 regenerating tree species among which Shorea robusta has maximum density (18,046 seedlings per ha) followed by Aporosa sp., whereas minimum density (19 seedling per ha) was recorded for Cassia nodosa, Litsea glutinosa, Grewia asiatica and Syzygium cumini, respectively. Relative density, relative frequency and relative abundance were estimated to assess the Importance Value Index (IVI) of the seedlings of different tree species. IVI of S. robusta was highest (66.25 out of 300) followed by Mallotus philippensis (27.33). G. asiatica, Derris robusta, and L. glutinosa showed the lowest IVI (0.93) among the regenerating tree species. Distribution of seedlings into different height classes showed that maximum number (31.4%) of seedlings in the height range of 50 - <100 cm. Among the recorded seedlings, Protium serratum showed maximum (11%) recruitment success. Alien invasive species, pineapple and banana based participatory agroforestry, frequent occurrence of fire, extensive collection of fuelwood and litter are the potential threats to the natural regeneration of Madhupur National Park.

Abstract
Introduction: Inflammation is a major cause of arthritis. Since the conventional medicines used for the treatment of this disease have many side effects, herbal remedies can be proved to be effective in this case. So, the present study was aimed at investigating the quantitative detection of phytochemicals, screening of in vivo anti-inflammatory and the possible anti-arthritic activities of the crude methanol extracts of a traditional medicinal plant Macropanax dispermus leaves (MDML) and stem barks (MDMS). Methods: Quantitative screening of phytochemical constituents was analyzed by standard procedures. The in vivo anti-inflammatory activity was conducted on Swiss albino mice by using carrageenan and formalin-induced paw edema tests, and xylene-induced ear edema test. The possible anti-arthritic activity was done by evaluating the in vitro inhibition of bovine serum albumin (BSA) denaturation. Results: The current research showed that MDML contained a considerable amount of flavonoids and alkaloids, and MDMS contained a considerable amount of phenols. MDMS (200, 400 mg/kg) was observed to be an effective and significant (P < 0.001) peripheral anti-inflammatory agent in carrageenan and formalin-induced paw edema tests, whereas MDML (400 mg/kg) was observed to have an effective and significant (P < 0.001) neurogenic anti-inflammatory effect in xylene-induced ear edema test as compared to the negative control group. MDMS was observed to be an effective anti-arthritic agent as compared to that of the negative control group. All those effects were dose and concentration-dependent.Conclusion: The present research proved that MDML and MDMS were effective medications for the treatment of inflammation and arthritis.

Abstract
This research describes an investigation of the antipyretic and hepatoprotective properties of both a crude organic extract and various subfractions of the ethnomedicinal plant Tinospora crispa, using appropriate animal models. In an attempt to identify potential lead hepatoprotective compounds, in silico experiments were utilized. Antipyretic activity was assessed via the Brewer's yeast-induced pyrexia method, while hepatoprotective effects were evaluated in a carbon tetrachloride (CCl4)-induced animal model. A computer-aided prediction of activity spectra for substances (PASS) model was applied to a selection of documented phytoconstituents, with the aim of identifying those compounds with most promising hepatoprotective effects. Results were analyzed using Molinspiration software. Our results showed that both the methanol extract (METC) and various subfractions (pet ether, PEFTC; n-hexane, NHFTC; and chloroform, CFTC) significantly (p < .05) reduced pyrexia in a dose-dependent manner. In CCl4-induced hepatotoxicity studies, METC ameliorated elevated hepatic markers including serum alanine amino transferase (ALT), aspartate amino transferase (AST), alkaline phosphatase (ALP), and total bilirubin. Malondialdehyde (MDA) levels were significantly reduced, while superoxide dismutase (SOD) levels were significantly increased. Among a selection of metabolites of T. crispa, genkwanin was found to be the most potent hepatoprotective constituent using PASS predictive models. These results demonstrate that both the methanolic extract of T. crispa and those fractions containing genkwanin may offer promise in reducing pyrexia and as a source of potential hepatoprotective agents.

Abstract
Abstract
Background
The Bangladeshi rural and hilly areas people have long tradition to use various medicinal plants for treating different diseases. That’s why, the crude methanolic leaf extract of Ardisia solanacea with its different fractions (petroleum ether, carbon tetrachloride, n-hexane and chloroform fractions) were subjected to investigate bioactivities in swiss albino mice; namely analgesic, CNS, and Oral hypoglycemic activities, while in-vitro evaluation of cytotoxicity.
Methods
Central nervous system activity was investigated by various method such as Elevated plus maze, Hole board, Hole cross and Open field test apparatus. Analgesic activity was evaluated by both acetic acid induced and tail immersion method. Hypoglycemic activity was evaluated by oral glucose tolerance test and cytotoxicity was evaluated by Brine shrimp lethality bioassay.
Results
In CNS activity, among others fractions, ASCF fraction produced a significant anxiolytic activity in both elevated plus maze and Hole board test. During open-field test almost all the fractions of A. solanacea leaves extract display decreased locomotor activities that indicates significant sedative activity. The ASME and ASCF showed significant peripheral analgesic activity at a dose of 200 mg/kg and 400 mg/kg body weight (p < 0.05). In tail immersion method, among others extracts chloroform fractions exhibited significant (p < 0.05) elongation of reaction time 30 min after oral dose of 200 and 400 mg/kg body weight respectively. The methanolic and n-hexane extracts reduced blood glucose level significantly after 90 min with value of 53.94% and 48.15% respectively (p < 0.05). In case of cytotoxicity activity, among other fractions carbon tetrachloride fraction showed lowest LC50 values.
Conclusions
From the above results, it is clear that different fractions of A. solanacea showed significant pharmacological potentiality in different in-vitro and in-vivo study model. So, it will be very much possible source for an isolating lead compound for curing the numerous disorders.

Abstract
The synthesis and the characterisation of silicon nanowires (SiNWs) have recently attracted great attention due to their potential applications in electronics and photonics. As yet, there are no practical uses of nanowires, except for research purposes, but certain properties and characteristics of nanowires look very promising for the future. Graphical abstractSemiconductor nanowires are attracting more and more interest for their applications in nanoscience and nanotechnology. The characteristic of the nanowires is their geometry with a diameter in the range of a few nanometers and a length far greater than their diameter. The structural defects often lead to mechanical defects. By reducing the number of defects per unit length, decreasing the lateral dimensions, crystalline nanowires are expected to be more resistant than the solid. Recently nanowires are attracting intense interest for solar energy conversion. In this review, we summarize the different methods of nanowires production and their applications. Special focus will be kept on silicon nanowires.

Abstract
Textile industries are the major contributor to environmental pollution and health hazards by generating huge amount of effluents that contain several pollutants and coloring agents. The concentration of these pollutants can be reduced to the permissible limit with the help of an Effluent Treatment Plant (ETP). The study was conducted to observe the textile effluent management techniques of an Effluent Treatment Plant (ETP) of Fakir Knitwear Limited (FKL), Narayanganj, Bangladesh. FKL set up a biological treatment plant to treat the effluent generated by the industry. Different effluent quality parameters were investigated at different stages in ETP. The effluent of the outlet was dark colored probably because of soluble coloring materials of the effluent but it is comparatively better than that of raw wastewater. There were found higher EC values than the standards which indicated that the greater amount of salts in the water due to dumping of solid wastes and discharging of industrial effluents. The highest TDS value 2054 ppm was observed at the screening pit unit than the other parts of the ETP. The highest DO was found 4.58 ppm in clarification tank which was within the standard value of aquaculture. The study also showed that the lowest BOD (24 ppm) and COD (145 ppm) was found at the outlet which was comparatively better than others. Although the effluent from the outlet contained pollutants, these effluent quality was comparatively good than the untreated waste water discharged from the industry. After treatment, the effluent of outlet moderately ensures the standard quality for aquaculture and irrigation. The results suggested that it is obvious to run the ETP regularly to improve the quality of effluents to save our native environment from the harmful effects of wastewater.J. Environ.

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
The present research work was conducted from July 2008 to June 2009 to investigate intensity of infestation of parasites in freshwater fishes and the impact of fish diseases on fish production in northern region of Bangladesh. Possibility of out break of diseases due to deterioration of environmental factors of water bodies was included in this study. The diseases identified were ulcer diseases, EUS (Epizootic Ulcerative Syndrome), Ichthyophthiriasis, Trichodiniasis, Chilodoneliasis, Myxoboliasis, Dactylogyrosis, Gyrodactylosis, Argulosis, Pernicious anaemia, Red spot disease, Red Pest of freshwater eel, Mouth fungus, Branchiomysis, Abdominal dropsy and whirling disease. The infestation more occurred in young fishes than in adult fishes. The overall water qualities of water bodies fluctuated from July 2008 to June 2009. Physicochemical parameters have more or less significant combined effect on the deterioration of water quality as well as fish diseases. Gills were the most affected sites and parasites damaged gill filaments by rupturing blood capillaries, causing necrosis, coagulation and hemorrhage. The present study revealed the prevalence of different organisms in fishes, which are potential pathogen for them. Fishes were infested by parasites and other pathogens. From overall study it was observed that the parasites, bacteria and fungus were most important pathogen for outbreak of diseases. It was also observed that there was a direct relation between disease outbreak among fishes and environmental factors. Low alkalinity reduces the buffer capacity of water and badly affects the pond ecosystem, which in turn cause stress to the fish and become more susceptible to diseases. In case of low aquatic environmental temperature fish reduces metabolic activities, which in turn makes the fish more susceptible during the winter period towards parasitic infection.

Abstract
Zinc is being recognized increasingly as an important element in human growth, development and immunological function. It is probably the most intensely studied microelement in newborn nutrition. Zinc deficiency is common in young infants in the developing world and is associated with reduced immunocompetence and increased rates of serious disease. Preterm neonates are especially vulnerable because of preterm delivery and low birth weight. The preterm baby has very limited stored energy and needs an adequate supply of nutrient. Preterm infant have high zinc dietary requirements as 60% fetal zinc is acquired during third trimester of pregnancy. Low concentration of zinc was found in pre-term low birth weight babies in different studies. Studies showed that before supplementation serum zinc level in preterm low birth weight babies were 62+/-12.4 microgm/dl, 65 microgm/dl, 54+/-14.4 microgm/dl and after supplementation serum zinc level were 105.8+/-16.6 microgm/dl, 86.4+/-24.7 microgm/dl respectively. At the same time mean weight & length of supplementation and without supplementation group were 6084 gm vs. 5280 gm, 2779+/-638.7 gm vs. 2474.6+/-441.8 gm and length 23.7 cm vs. 21.4 cm, 46.49+/-2.6 cm vs. 44.1+/-2.8 cm respectively. So supplementation of zinc in preterm babies causes improved growth and development. Various reports showed beneficial effect of long supplement in early growth of pre-term babies. However long term follow up studies are needed to evaluate the beneficial effect of zinc supplementation on growth of preterm babies.

Abstract
Low birth weight (LBW) is a major child health problem in Bangladesh and continuing to great threat to child health and child survival in Bangladesh. LBW is a silent emergency but crisis is real and its persistence has profound and frightening impact on neonatal mortality. This observational study was conducted in Dhaka Shishu Hospital, Dhaka, Bangladesh during July 2004 to June 2005. Serum zinc levels were estimated between two groups: group-I preterm AGA (n=50), group II preterm SGA (n=50) babies. Blood samples were collected from the study population in neonatal unit and serum zinc levels were measured by flame atomic absorption spectrophotometry in Atomic Energy Center, Dhaka, Bangladesh. Observed data were made comparison among groups by Students 't' test. It was observed serum zinc level (60.2+/-15.2) in group I and (62.1+/-12.4) in group II. Serum zinc level was in lower limit of normal range in both groups with more lower level in preterm AGA babies but their difference was not statistically significant (p>0.05). So zinc supplementation may enhance the growth of preterm LBW babies in their early months of lives.

Abstract
This study analyzed a total of 1482 arsenicosis patients living in 6 of 496 upzilas (sub-districts) of Bangladesh, who were identified through household screening and then confirmed by a trained medical team headed by medical officer. Melanosis was common (97%) among them but about two-thirds (68.7%) of the patients were suffering from keratosis. Average age was 36 years and average duration of arsenic symptoms was 3 (median) years. About 50% of the patients had been drinking tubewell water more than 24 years. Melanosis was significantly associated with younger patients (P=0.031), shallower tubewell (P=0.005), and complication of conjunctivitis (P<0.001). Keratosis was also significantly associated with older age (P=0.022), shallower tubewell (P<0.001), complication of conjunctivitis (P<0.001), bronchitis (P<0.001), loss of appetite (P<0.001), and wasting (P<0.001). Duration of arsenic symptoms was significantly associated with older age (P<0.001), male (P=0.002), married (P<0.001), smoking (P=0.002), longer duration of consuming tubewell water (P<0.001), complication of conjunctivitis (P=0.002), loss of appetite (P<0.001), wasting (P=0.006), and social problem faced having arsenicosis (P=0.040). Multivariate odds ratio (OR) and 95% confidence interval (CI) indicated that keratosis (OR=2.00; 95% CI: 1.56-2.56) was significantly associated with longer duration of arsenic symptoms; loss of appetite (OR=1.40; 95% CI: 1.12-1.74) was a significant complication for longer duration. Similarly smoking (OR=1.33; 95% CI: 1.06-1.68) was positively associated with longer duration of arsenic symptom. These findings will help the policy makers of Bangladesh to understand about the factors that may affect the severity condition of the patients through prolongation of arsenic symptoms.

Abstract
Arsenicosis is presently one of the significant public health problems in Bangladesh. Employing household screening of over 3.6 million people living in 6 arsenic-affected Upzilas of Bangladesh, 1,503 arsenicosis patients were identified at first and then blood and urine were collected from some of them and analyzed through laboratory techniques. As the relation between blood and urine chemicals with duration of having arsenicosis (DHA) is not clear, this study presented all findings by shorter versus longer DHA. Complications namely chronic bronchitis, conjunctivitis/congestions, weakness, and wasting were common, with relatively higher rates in longer group. Logistic regression analysis adjusted for age, sex, education, smoking, duration of drinking tube-well water, and whether any arsenicosis patients were in the family-indicated higher odds ratio (OR) of longer DHA (LDHA) in 3rd tertile with respect to GOT (OR = 2.12; 95%CI: 1.09-4.13), and blood glucose (OR = 2.00; 95%CI: 1.07-3.72) than 1st tertile. The OR of LDHA was significantly lower (OR = 0.48; 95%CI: 0.25-0.93) in 3rd tertile for triglycerides compared with 1st tertile. Albumin/globulin (A/G) ratio of 2nd tertile showed significantly lower OR of LDHA (OR=0.51; 95%CI: 0.28-0.95) than 1st tertile. Further epidemiological investigations based on a large sample, through cohort or case control studies, may be useful for validating and generalizing the results in Bangladesh.

Abstract
Out of 350 acute respiratory tract infection (ARI) patients 110 (31.4%) were positive on culture. Among then (35.5%) yielded from upper respiratory tract infection (URI) and 64.5% yielded from lower respiratory tract infection (LRI). Predominant bacterial isolates from URI were Staph aureus (12.4%) and Strepto. pyogen (9.8%) whereas predominant agent from LRI were Strepto. pneumoniae (14.7%) and Haemophilus influenzae (8.6%). Capsular typing by polymerase chain reaction (PCR) and type specific antisera revealed that 64.7% of the isolates were type-b and rest were non-b. The most frequent resistance pattern of H. influenzae was found resistant to penicillin-ampicillin (64.7%) followed by SMX-TMP (14.7%) and tetracycline (5.9%). Among penicillin-ampicillin resistant strains, 81.8% were beta lectamase positive and 18.2% were beta lectamase negative. Among beta lectamase positive strains 66.7% were capsular type-b and 33.3% were non-b, had MICS < or = 8 microgram/ml. and < or = 4 microgram/ml. respectively. 5.9% strains of Strepto. pneumoniae was found resistant to SMX-TMP, 5.9% to penicillin-ampicillin and 2.9% to cephalexin. Common resistance pattern of Staph aureus was penicillin-ampicillin (60%), SMX-TMP (37.2%) and tetracycline-erythromycine-cephalexin (11.4%). Strepto. pyogen was found resistant to tetracycline in 12.2% cases and to SMX-TMP in 8.3% cases.
