    ABSTRACT: Giardia and Cryptosporidium are the pathogens which transmitted through contaminated soil and contaminated water are significant causes of diarrhea and nutritional disorders in institutional and community peoples. Children and immune compromise persons are more vulnerable for these infections. Both Giardiasis and Cryptosporidiosis were included in 2004 as WHO Neglected Disease. So this is a major public health problem in developing countries. The present study was carried out to detect the Giardia and Cryptosporidium from diarrheic or patient having loose stool by Direct Immunofluorescence assay. The study was conducted during July 20012 to February 2013 and the work was done in Mymensingh Medical College in the department of Microbiology and in Bangladesh Agricultural University in the department of Veterinary Medicine. A total of 100 loose stools were collected from school children of different area and hospital under sadar upazilla, Mymensingh. The detection of Giardia lamblia and Cryptosporidium parvum showed the individual prevalence 8% and 4% respectively. The highest cyst/oocyst count was 85,000 and 1,000/gm of stool and the lowest being 100 and 50/gm of stool for Giardiasis and Cryptosporidiosis respectively. The detection rate of Giardia and Cryptosporidium by Immunofluorescence assay was relatively higher than the previous study done in Bangladesh and this was the first report from Bangladesh over human stool specimen using Immunofluorescence assay. So, Immunofluorescence assay could be adapted for rapid and accurate detection of Giardia and Cryptosporidium.

    ABSTRACT: The study was undertaken to find out the correlation of elevated B-type Natriuretic Peptide (BNP) levels with the severity of coronary artery disease in patients with unstable angina and NSTEMI. This cross sectional analytical study was carried out in the department of cardiology, National Institute of Cardiovascular Diseases, Dhaka during a period of August 2011 to June 2012. A total of 100 consecutive patients with unstable angina and NSTEMI undergoing coronary angiography were included in the study. BNP assay was done by Architect system, a chemo luminescent microparticle immunoassay (CMIA). CAG was done by conventional method within 14 days of index hospital admission. Study patients were divided into two groups on the basis of BNP levels. In Group I, BNP Levels were ≤80pg/ml and in Group II, BNP levels were elevated >80pg/ml. with 50 patients in each group. Angiographic severity of CAD was assessed by vessel score and Friesinger score. Vessel score showed single vessel was involved in 21(47.7%) patients while multi vessel in 23(52.3%) patients was found in Group I. On the contrary 11(22.4%) single vessel patients and 38(77.6%) multivessel patients were found in Group II. There was significant association between vessel involvement (p=0.01). Friesinger score reveled that less severe CAD was found in 22(44%) patients and significant severe CAD in 28(56.0%) patients in Group I. On the contrary 7(14.0%) less severe CAD patients and 43(86.0%) severe CAD patients were found in Group II. There was significant difference between severity of CAD among the study groups (p=0.01). There was linear correlation between BNP pg/ml and coronary artery disease severity in terms of Vessel score (r=0.38, p=0.01) and Friesinger score (r=0.51, p=0.01). The present study concluded that increased BNP level >80pg/ml was signi?cantly associated with the presence and severity of CAD in patient with UA and NSTEMI.

    ABSTRACT: An ester-based mutual prodrug (aceclofenac–paracetamol; AC-PR) was synthesized (one-pot method) with an aim of improving the therapeutic index through prevention of gastrointestinal irritation and bleeding that is associated with aceclofenac. The release of aceclofenac and paracetamol from the ester prodrug (AC-PR) was studied by reverse phase HPLC in hydrochloric acid buffer (pH 1.2), phosphate buffer (pH 7.4), 80 % v/v human plasma, 10 % w/v rat intestinal homogenate and 10 % w/v rat liver homogenate (pH 7.4). The prodrug showed negligible hydrolysis at pH 1.2 as compared to pH 7.4, suggesting that very less of the prodrug would hydrolyze in stomach, but would release the parent drugs at pH 7.4 in adequate amounts. The prodrug showed enhanced anti-inflammatory activity and significant protection against acetic acid-induced writhings (analgesic activity) as compared to that of aceclofenac. Further, the prodrug produced reduced number of ulcers as compared to that of the parent drug. These results suggest that the synthesized mutual prodrug (AC-PR) is better in terms of activity and GIT toxicity than the parent drug.

    ABSTRACT: The purpose of this study was to determine the usefulness of color doppler sonography and resistivity index (RI) in differentiating liver tumors. The study was carried out in the Department of Radiology and Imaging, Mymensingh Medical College Hospital, and Institute of Nuclear Medicine and Allied Sciences (INMAS), Mymensingh, Bangladesh, during the period of July 2009 to June 2011. Total 50 consecutive cases were studied. Among them 27 were hepatocellular carcinomas, 19 were metastatic tumors, 03 were hemangiomas and 01 was hepatic adenoma. Doppler sonographic findings were then correlated, case by case, with final diagnosis- either pathologically by USG guided Fine-needle aspiration or by other imaging modalities (e.g., CT scan and RBC liver scan for hepatic hemangioma). The RI value of hepatocellular carcinoma was 0.69±0.096 and in metastatic tumors 0.73±0.079. The results showed no significant difference between the RI of hepatocellular carcinomas and metastatic liver tumors but it was significantly higher than benign lesions (p<0.05). RI of hemangiomas was 0.49±0.64 and in one hepatic adenoma was 0.65. When RI was <0.6 for benign liver tumors and ≥0.6 for malignant tumors we calculated a sensitivity of 89.14%, specificity of 66.7%, accuracy of 85.71% positive predictive value of 97.62% and negative predictive value of 28.57% in differentiating benign and malignant tumors. Thirty four of 46(73.9%) malignant lesions had intratumoral flow and 25% of benign lesions also showed intratumoral flow. The difference of intratumoral flow between malignant and benign lesions was significant (p<0.01). Two of 4 benign lesions (50%) had peritumoral vascularity where 6% of the malignant tumors showed peritumoral vascularity. In conclusion, combined studies of the type of intra-and peri-tumoral flow signals in CDFI and the parameter of RI would be more helpful in the differential diagnosis of benign and malignant liver tumors.

    ABSTRACT: PDE-IV is one of the important targets in the treatment of asthma, COPD, and rheumatoid arthritis. In the search for novel PDE-IV inhibitors a 3D-QSAR study was performed on PDE-IV inhibitors by means of pharmacophore mapping using PHASE, Schrödinger-9. The 3D-QSAR obtained from AAHHRR-1024 hypothesis was found to be statistically significant with r 2 = 0.9766 and q 2 = 0.8759 with 7 PLS factors. The statistical significance of the model was confirmed by a very low value of RMSE 0.4795. The "Pearson-R" value of 0.9376 suggests a very good predictive ability of the hypothesis generated. The present study demonstrates a robust 3D-QSAR model of PDE-IV inhibitor with the help of AAHHRR-1024 hypothesis, which will help in designing novel inhibitors.

    ABSTRACT: In view of the potential pharmacophoric nature of imidazole nucleus, two series of imidazole derivatives, 2,4-disubstituted-1 H-imidazoles (2a-m) and 1,2,4-trisubstituted-1 H-imidazoles (3a-m), were synthesized with an aim of obtaining dual acting compounds i.e., anti-inflammatory and antifungal agents. The title compounds were synthesized from 4-methoxyphenyl glyoxal (1) following multistep synthesis, and their structures were established on the basis of modern analytical techniques (IR, NMR and MS). The synthesized imidazoles were tested for their in vivo anti-inflammatory activity. In addition to that, some compounds were also evaluated for their analgesic and ulcerogenic effects. The compounds were also evaluated for their in vitro antifungal activity. Di- and tri-substituted imidazole derivatives (2a-m and 3a-m) were successfully synthesized. In in vivo anti-inflammatory test, six compounds (2 h, 2 l, 3 g, 3 h, 3 l and 3 m) exhibited good anti-inflammatory activity (49.58 to 58.02% inhibition) with minimal GI irritation (severity index; 0.17 to 0.34). These compounds were also tested for their analgesic activity and showed appreciable protection (40.53 to 49.60% protection) against saline-induced writhing test. Indomethacin was used as standard drug for comparison. In antifungal test, two compounds (3 h and 3 l) displayed appreciable antifungal activity (MIC; 12.5 μg mL(-1)) against the fungal strains tested. Two compounds, 2-(4-nitrophenyl)-4-(4-methoxyphenyl)-1-phenyl-1H-imidazole (3 h) and 2,4-di-(4-methoxyphenyl)-1-phenyl-1H-imidazole (3 l), emerged as lead compounds having dual biological activities; good anti-inflammatory as well as antifungal effect with lesser GI irritation.

    ABSTRACT: The present study was carried out in the department of Neurology and Medicine, Mymensingh Medical College Hospital, Bangladesh during the period of January 2009 to December 2010 to see the electrolyte changes in stroke. The serum concentration of Na+, K+, and Cl- were measured in 110 cases during acute period of stroke (55 ischemic and 55 haemorrhagic strokes). Data were analyzed by computer with SPSS programme using 't' test and chi square test. In haemorrhagic stroke, out of 55 patients 29(52.72%) had abnormal sodium level, of them 23(41.8%) had hyponatremia, 6(10.9%) had hypernatremia. In contrast in ischemic stroke 23(41.80%) out of 55 had abnormal sodium level, of them 21(38%) had hyponatremia. The result showed that hyponatremia is almost equally common in both haemorrhagic and ischaemic group without significant difference (p>0.05). The study also revealed that hyponatremia is more common than hypernatremia in both groups. Mean±SD of age of the haemorrhagic group was 60.80±15.97 while the age of ischaemic group was 59.89±15.84 years. Male, female ratio in haemorrhagic and ischaemic group 1:0.62 and 1:0.89 respectively. Mean±SD of serum Na+, K+, Cl- in haemorrhagic group were 136.18±10.5, 3.83±0.65, 97.96±16.74 mmol/L, in ischaemic group 135.08±9.08, 4.00±0.75, 100.27±8.39 mmol/L. The result showed no significant difference in haemorrhagic and ischemic stroke. Hyponatremia, hypokalamia and hyperchloredemia were more common than hypernatremia, hyperkalamia and hyperchloredemia. In haemorrhagic stroke, out of 55 patients, 21(38.18%) had abnormal potassium level, of them 19(34.55%) had hypokalemia, 2(3.63%) had hyperkalemia. In contrasts, in ischemic stroke, 15 out of 55(27.22%) had abnormal potassium level. Of them 12(21.81%) had hypokalemia and 3(5.45%) had hyperkalemia. The finding showed that hypokalemia is almost equally common in both haemorrhagic and ischaemic group without significant difference. The study also revealed that hypokalemia is more common than hyperkalemia in both groups. In haemorrhagic stroke, out of 55 patients 33(60%) had abnormal chloride level. Of them 20(36.4%) had hypochrloridemia, 13(23%) had hyperchrloridemia, in contrast, in ischemic stroke, 40 out of 55(60%) had abnormal chloride level, of them 22(40%) had hypochrloridemia and 18(32.7%) had hyperchrloridemia. The result showed that changes in chloride level after haemorrhagic and ischemic stroke are similar. The result showed hypochrloridemia is more common than hyperchrloridemia in both groups.

    ABSTRACT: Titanium dioxide (TiO 2) has been used as photo-catalyst for the degradation of reactive yellow (RY) in batch and continuous mode under UV irradiation. Titanium dioxide (TiO 2) was immobilized onto the ceramic plate using cement as binder. The effects of various parameters such as initial dye concentration, solution layer thickness, presence of catalyst, residence time, and catalyst loading on degradation have been investigated. The results showed that without catalyst no degradation was achieved. The maximum sorption capacity of TiO 2 was found to be 0.01447 kg/kg. The degradation of RY followed pseudo-first order kinetics with rate constant k = 0.001 min -1 . A decrease in degradation of RY was observed with an increase in initial concentration and solution layer thickness. A comparison of photocatalytic performance between batch and continuous mode was performed and the batch mode provided better degradation performance. About 60% degradation of dye was achieved at 360 min for 200 ppm RY solution in batch mode. Abstract doi:

    ABSTRACT: Barium titanate (BaTiO3) nanoparticles were synthesized via an electrochemical route from Ti metal plate at room temperature. Structural, compositional and optical properties were characterized by XRD, SEM, EDX, FTIR, UV-Vis and photoluminescence (PL) spectroscopy. X-ray diffraction (XRD) confirmed the preferential growth of BaTiO3 nanoparticles that width is ~15 nm in the (110) orientation. The SEM image shows the synthesized BaTiO3 were nanowires in shape. The EDX measurements confirm that the composition of the samples was Ba, Ti and O elements. UV-Vis Spectroscopy shows the absorption peak at ~330 nm. PL measurements reveal an intense and broad band at around the green colour emission region.

    ABSTRACT: The present study has been designed to compare the postoperative pain relief for inguinal hernia repair in children through wound infiltration with levobupivacaine with that provided by paracetamol administration per rectaly. This interventional study was carried out in the Department of Paediatric surgery, Mymensingh Medical College Hospital, Mymensingh and Dhaka Medical College Hospital, Dhaka, during the period from January 2009 to September 2010. A total of 120 patients were included in this study. Among them 60 patients in Group-A (study group) where post incisional wound infiltration with levobupivacain after inguinal herniotomy and before skin closure was done and 60 patients in Group-B (control group) where paracetamol was given per rectally after anesthesia induction. Both groups were followed up post operatively for 23 hours. In Group A maximum analgesic period was 8.30 hours and minimum analgesic period was 5.30 hours. On the other hand in Group B maximum analgesic period was 6.50 hours and minimum analgesic period was 4.50 hours. Duration of post operative analgesia between two groups of the patients were significant [p<0.01]. Post incisional wound infiltration with levobupivacain has significantly better efficacy to rectal administration of paracetamol with respect to providing pain relief following inguinal hernia repair in children. Longer duration of analgesic action is more achieved in the Levobupivacaine group.

    ABSTRACT: Dual cyclooxygenase/lipoxygenase (COX/LOX) inhibitors constitute a valuable alternative to classical nonsteroidal anti-inflammatory drugs (NSAIDs) and selective COX-2 inhibitors for the treatment of inflammatory diseases. A series of 3-(5-phenyl/phenylamino-[1,3,4]oxadiazol-2-yl)-chromen-2-one and N-[5-(2-oxo-2H-chromen-3-yl)-[1,3,4]oxadiazol-2-yl]-benzamide derivatives were synthesized and screened for anti-inflammatory, analgesic activity. All the derivatives prepared are active in inhibiting oedema induced by carrageenan. Compound 4e was found more potent with 89% of inhibition followed by compound 4b (86%). Compounds with >70% of anti-inflammatory activity were tested for analgesic, ulcerogenic, and lipid peroxidation profile. Selected compounds were also evaluated for inhibition of COXs (COX-1 and COX-2) and LOXs (LOX-5, LOX-12, and LOX-15). Compound 4e was comparatively selective for COX-2, LOX-5, and LOX-15. Study revealed that these derivatives were more effective than ibuprofen with reduced side effects. It can be suggested that these derivatives could be used to develop more potent and safer NSAIDs.

    ABSTRACT: ABSTRACT The epidemiology of rotavirus infection in human, calves, sheep, goats and poultry were studied. Among total of 800 collected fecal samples , 320 samples from human, 125 samples from calves, 82 samples from sheep, 7 samples from goats, 267 samples from poultry were collected from July 2010 to May 2011 and examined by Polyacrylamide Gel Electrophoresis and Silver Staining (PAGE-SS) technique for the detection of presence of rotavirus dsRNA. Human rotavirus was detected 10.94 % (35/320) in diarrhoeic fecal samples. The highest prevalence was recorded in September 33.33% and the lowest in May 4.54%. The prevalence of rotavirus infections was 33.33% in autumn (September), 11.69% in late autumn (OctoberNovember), 9.6% in winter (December-January), 9.72% in spring (February- March), 6.12% in summer (April-May) season in diarrhoeic samples indicated the presence of rotavirus in human round the year in Bangladesh and as such no marked seasonal variation in rotavirus infection in human. No calves, sheep and goat fecal sample was found positive for rotavirus on PAGESS technique. During the study period, 267 faecal samples (diarrhoeic and nondiarrhoeic) of chicken (from one day to one month of age) were tested and only one was found positive on PAGE-SS technique for rotavirus infection (0.38%; 1/267). The positive cases were found in samples collected in winter season from layer chicks aged 10 days. The migration patterns of detected positive strains were not similar on polyacrylamide gel electrophoresis and their migration speed was different types. Five electropherotypes were determined among 35 human rotavirus positive samples. All the electropherotypes were under group A and long pattern. The genome migration of avian rotavirus was distinct from human types and under group D and long pattern. In the present study, it was not investigated that bacteria, parasite or any other viruses which might be responsible for development of diarrhoea.
