[Show abstract][Hide abstract] ABSTRACT: An investigation was carried out to evaluate the efficacy of some selected seed treatments on the incidence and severity of sheath blight (ShB) disease and yield contributing characters of imported hybrid rice in the Seed Health Laboratory of the Department of Plant Pathology and the field of Sher-e-Bangla Agricultural University farm, Dhaka, Bangladesh during the period of November 2009 to December 2010. Eleven seed treating agents viz. untreated control, sun drying, polythene solarization, brine solution, neem leaf extract (Azadirachta indica), allamanda leaf extract (Allamanda cathartica), hot water treatment, Provax 200 (carboxin), Bavistin 50 WP (carbendazim), Dithane M 45 (mancozeb) and Trichoderma harzianum were evaluated against the incidence and severity of sheath blight disease at three growth stages (flowering, milking and maturity) and yield contributing characters. It was observed that disease incidence and severity was gradually increased from flowering stage to maturity stage with the age of the plant and minimum incidence and severity gave the maximum yield. Disease incidence and severity caused by Rhizoctonia solani varied from 15.87% to 20.30% and 6.47 to 7.80 (0-9 scale), respectively at maturity stage where hot water treatment showed the best result followed by Provax 200. The highest values of plant height, panicle length, effective panicle and filled grain were recorded under the fungicidal seed treatments followed by hot water treatment. The highest grain yield (10.40 t ha-1

A total of 60 cases of typhoid fever were enrolled in to a randomized clinical trial and was divided into two groups. The inclusion criteria of the cases were: Documented fever for more than 4 days plus two or more of the following clinical features: toxic physical appearance, intestinal complaints, coated tongue, ceacal gurgling, hepatomegaly and splenomegaly, diarrhoea and constipation plus positive Widal test and/or blood culture positivity. Patients who had complication like GIT heamorrhage; intestinal perforaion and/or shock were excluded from the study. Data were collected in a structured questionnaire. Azithromycin was given at a dose of 10mg/kg/day for a period of 07 days Cefixime was given at a dose of 20mg/kg/day in two divided dose for 14 days. The mean time of defervesence was 4.05+1.14 days with azithromycin and 3.41+0.95 with cefixime respectively. The minimum defervesence time was 02 days and maximum defervesence time was 07 days. Clinical cure rate was 87% in azithromycin group and 93% in cefixime group. No serious adverse effect was noted related to azithromycin and cefixime therapy except nausea, vomiting, diarrhoea and jaundice. It was found that azithromycin is almost as effective as cefixime in the treatment of typhoid fever.
[Show abstract][Hide abstract] ABSTRACT: This study was done to find out the correlation between various grades of Intraventricular Hemorrhage (IVH) and stages of HIE in perinatal asphyxia and to determine the short-term outcome of the affected baby. This observational study was conducted in Neonatal ward of Dhaka Shishu Hospital (DHS) and Dhaka Medical College Hospital for period of 37 months from January 2004 to January 2007. Total 189 perinatally asphyxiated babies were enrolled for HIE staging and cranial Ultrasonogram (USG) to find out grades of IVH. Finally 178 newborns were fulfilling all the necessary criteria for statistical analysis of the collected data on prescribed questionnaire. Among 178 perinatally asphyxiated newborns HIE stages - I, II, III were 50(28%), 10(56%) and 28(16%) respectively. Out of this 178 neonates total 50(28%) developed various grades IVH. Grades of IVH, I, II, III, IV were 15(30%), 18(36%), 10(20%) and 7(14%) respectively. There was significant correlation between the severity of HIE staging and grades of IVH. Short term outcome was poor in HIE-III, IVH grade III and IV. There is a direct relationship between different grades of IVH and stages of HIE. That is more the severe stages of HIE there is more chances to develop severe grades of IVH, Immediate morbidity and mortality is dependent on the grades of IVH and severity of stages of HIE.
[Show abstract][Hide abstract] ABSTRACT: This prospective, comparative and interventional study was done to compare the effects of Trabeculectomy with Mitomycin-C and medical treatment with Timolol maleate 0.5% by controlling IOP (intra ocular pressure) and assessing the visual acuity (VA) and mean sensitivity (MS) of visual field in moderate stage of steroid induced glaucoma and conducted in the Department of Ophthalmology, Bangabandhu Sheikh Mujib Medical University, Dhaka, from July 2004 to June 2009. Sixty eyes of thirty patients with glaucoma due to use of topical steroids for >1 year. IOP range was 22-30 mm of Hg, visual field with (MD) mean deviation >6 to 12 dB and (MS) mean sensitivity >12-21dB, C:D ratio 0.7-0.8 and visual acuity 6/9 to 6/6 were included in this study. At first, topical steroid was stopped. Sample was collected in lottery method. Patients were divided into two groups. In Group I, 30 eyes were treated with Timolol maleate 0.5%. In Group II, 30 eyes were treated surgically by Trabeculectomy with Mitomycin-C. Follow-up were done on 1st POD, after 7 days, 1 month, 3 months and 6 months. Successful IOP control (<15mm of Hg) were achieved in 23 eyes (77%) in Group I and 30 eyes (100%) in Group II and were highly significant (p<0.001). Visual acuity and mean sensitivity also improved more in Group II than the Group I. It was also highly significant (p<0.001). So, Trabeculectomy with mitomycin-C is effective procedure in comparison to medical treatment for steroid induced glaucoma.

[Show abstract][Hide abstract] ABSTRACT: The study was undertaken to measure the effects of Beta blocker (Timolol maleate 0.5%) in moderate and advanced stage of primary open angle glaucoma by controlling intra-ocular pressure (IOP) and assessing the visual acuity (VA) and mean sensitivity (MS) of visual field. Study was done in the department of Ophthalmology, Bangabandhu Sheikh Mujib Medical University, Shahbagh, Dhaka from January 2002 to December 2005. It was a Prospective and interventional study. Thirty patients of bilateral primary open angle glaucoma were treated medically by B-blocker (Timolol maleate 0.5%) two times daily. Follow up were done after 7 days, 1 month, 3 months and 6 months. Before treatment Intra ocular pressure (IOP) range was 22-30 mm of Hg (mean 23.40±2.04). After beta-blockers IOP reduced to the range of 10-20mm of Hg (mean 13.12±2.01) which was statistically significant (p>0.02) in moderate stage & 8-18mm Hg (mean 13.50±2.0) in advance stage which was also statistically significant (p<0.02). VA and MS also improved in 15 eyes (50%), remained unchanged in 9 eyes (30%) and deteriorated in 6 eyes (20%) in moderate stage and also improved in 15 eyes (50%), remained unchanged in 6 eyes (20%) and deteriorated in 9 eyes (30%) in advanced stage. Success rate was 80% in moderate (p>0.02) & 70% in advanced stage (p<0.02) and which was statistically significant.
[Show abstract][Hide abstract] ABSTRACT: Beta-thalassemia which is one of the most common genetic disorders in Bangladesh encompasses a group of monogemic diseases that have reduced synthesis or no synthesis of one or more globin chain of haemoglobin. The defects involved are extremely heterogenous and give rise to a large phenotypic spectrum with patients that are almost asymptomatic to cases in which regular blood transfusions are required to sustain life. The aim of the study is to estimate the frequency of beta thalassemia among the blood recipients in the Day Care Centre of Transfusion Medicine Department of Mymensingh Medical College Hospital from July, 2009 to June, 2010 along with their chelation habit. Retrospective cross-sectional study with the sample size of 784, clinical and family data was collected and descriptive statistics were done in the Laboratory of Transfusion Medicine Department. Among the 784 subjects, the beta thalassemia was 521 (66.46%), among the thalassemic patients only 59(11.32%) take injection Dysferrioxamine (Dysferol), the iron chelating agent. Male are predominant than female (63.53%). Those of the affected patients 67.18% were in age group 6 to 20 years. Although beta thalassemia is one of the first monogemic diseases and represents a global health problem, only recently has the scientific community started to focus on the real molecular mechanisms that underline this disease, opening new & exciting therapeutic perspectives for thalassemic patients worldwide. It is concluded from our study that availability of blood transfusion facilities along with an orally and cheaper iron chelator is an urgent need to ensure the management of needy thalassemic patients in Bangladesh.
[Show abstract][Hide abstract] ABSTRACT: Many countries in the world have reported human infections by chikungunya virus (CHIKV) a mosquito-borne togavirus belonging to the genus alpha virus. After half a century of focal out breaks of acute febrile poly arthralgia, the disease had spread unexpectedly in the past decade with large outbreaks in Africa around the Indian Ocean and in Bangladesh. In Asia, CHIKV is thought to be transmitted by the same mosquito as dengue, Aedes aegypti and Aedes albopictus. Due to similarities in clinical presentation with dengue, limited awareness and a lack of laboratory diagnostic facilities, CHIKV is probably often under diagnosed or misdiagnosed as dengue. Treatment is supportive. The prognosis is generally good although some patients experience chronic arthritis. There is no vaccine or antiviral therapy against CHIKV. Early identification of disease and control of vector will prevent the spread of disease.
[Show abstract][Hide abstract] ABSTRACT: New developments in the epidemiology, treatment and prognosis of thalassemia have dramatically altered the approach to the care of affected patients. In the last 30 years, conventional treatment of β-thalassemia major, based primarily on regular blood transfusions and iron chelation therapy with desferrioxamine (DFO) has markedly improved the prognosis of the disease. Adequate administration of parenteral DFO reduces or prevents iron accumulation. The unavailability of DFO (dysferol) for most patients with thalassemia major and the failure of prescribed therapy to prevent complications in other patients have led to a search for alternative iron chelators; one of them, deferiprone (DFP) has been commercially available. Patients may ultimately benefit from having a choice between several chelators, including orally active drugs. Combination therapy and organ-targeted chelation, may soon have a considerable impact on the therapeutic outcome and quality of life of patients with thalassemia.
[Show abstract][Hide abstract] ABSTRACT: An observation study was carried out in the department of Paediatrics in Mymensingh Medical College Hospital, Mymensingh regarding urinary tract infection (UTI) in children aged ≤15 years from January 2008 to December 2008. The objectives of this study were to review symptoms, causative agents, antimicrobial sensitivity test, abnormalities of urinary tract and treatment of children with UTI. Fifty cases of childhood UTI, based on urine routine examination and culture, were analyzed and male female ratio was 1:1.3. Sixteen (32%) children were less than one year old. Fever was the most common clinical presentation (82%). Pyuria was detected in 92% of cases. Most common causative organism was Eschericia coli (E. coli) (70%). Susceptibility of E. coli to ceftriaxone, levofloxacin, amikacin and nitrofurantoin was greater than 80% and less susceptible to cotrimoxazole, ampicillin, cephradine and ciprofloxacin. Most of the patients became afebrile within 5 days after starting antimicrobial therapy.
[Show abstract][Hide abstract] ABSTRACT: Twelve agronomic characters viz. days of first flowering (DFF), plant height at first flower (PHFF), number of primary branches at first flower (NPBFF), number of secondary branches at first flower (NSBFF), number of secondary branches at maximum flower (NSBMF), plant area per plant (PAPP), plant weight per plant (PWPP), root weight per plant (RWPP), number of pods per plant (NPdPP), pod weight per plant (PdWPP), number of seeds per plant (NSPP) and seed weight per plant (SWPP) were studied for component of variation, coefficient of variability and heritability, genetic advance and genetic advance expressed as percentage of mean in six M3 lentil (Lens culinaris Medic.) lines. The range of variation was pronounced in all the characters. The lines were genetically differentiated as indicated by the analysis of variance. The different components of variation and coefficient of variability were high for NSPP, NPdPP, PAPP and NSBMF, which indicated a wide scope of improvement of these traits through selection. Heritability and genetic advance were estimated to below for all the characters. Comparatively high heritability values were noted for NSBFF and PHFF.
[Show abstract][Hide abstract] ABSTRACT: Typhoid fever still continues to be a major public health problem, particularly in many developing countries. A simple, reliable, affordable and rapid diagnostic test has been a long-felt need of the clinicians. We, therefore, prospectively evaluated the sensitivity and specificity of Typhidot (IgM), a serological test to identify IgM antibodies against Salmonella typhi. The study was carried out in the department of Microbiology, Mymensingh Medical College, Mymensingh between June, 2006 and July, 2007, on a total of 100 samples from clinically suspected patients to have typhoid fever. Blood culture as well as Typhidot test were performed for each of the cases. Out of 100 clinically diagnosed typhoid fever, 14 were blood culture positive for S. typhi and 73 were Typhidot (IgM) positive. Among 14 culture positive cases, 13 (92.85%) were Typhidot (IgM) positive. The test was also positive in 04 (20%) out of 20 febrile controls. None of the healthy controls was positive by Typhidot (IgM). The sensitivity, specificity, positive predictive value and negative predictive value of the test using blood culture as gold standard were 92.85%, 90.00%, 76.47% and 97.29% respectively for typhoid fever. Typhidot (IgM) test is rapid, easy to perform and reliable test for diagnosing typhoid fever, and useful for small, less equipped laboratories as well as for the laboratories with better facilities.
[Show abstract][Hide abstract] ABSTRACT: This case control study was carried out in the Paediatric wards of Mymensingh Medical College Hospital for a period of one year from April 2002 to March 2003 to determine the sensitivity, specificity and predictive values of Aldehyde test in the diagnosis of Kala-azar. A total of seventy five febrile cases of Kala-azar from Paediatric wards were enrolled in the study and Seventy five controls having splenomegaly with or without fever were also included from the same source. Aldehyde test was done in both cases and controls. Diagnosis of Kala-azar was confirmed by demonstration of Leish-man-Don-o-van body (LD) in bone marrow or splenic aspirates. Out of 75 parasitologically proven cases of Kala-azar, AT was positive in 56 cases. The sensitivity irrespective of duration of illness was 74.6%. We found sensitivity of AT increases with the duration of illness where AT was sensitive in 34.7% cases having fever for less than 3 months, 90.90% with fever for 3 months to less than 6 months and 100% with fever for 6 months or more in duration. Specificity of AT was calculated as 96% with positive and negative predictive values of 94.9% and 79.1% respectively. So AT is a very sensitive and specific test with high positive and negative predictive values. Considering the cost, availability, simplicity, sensitivity, and specificity we would recommend the Aldehyde test as an important diagnostic tool for field diagnosis of Kala-azar especially after three months of febrile illness.
[Show abstract][Hide abstract] ABSTRACT: Studies were carried out on the preparation of powerful phenyl from petuli (Trewia nudiflora linn) seed oil. It was found that petuli seed contains 22 % of pale-yellow coloured oil. The physical and chemical characteristics of the oil were determined by the conventional methods and the fatty acid by gas liquid chromatography (G.L.C). From the results it is evident that the oil can be used suitably for the preparation of powerful phenyl on accounts of its high α-elaeostearic acid (38 %) a major fatty acid component content and higher saponification value (185). This phenyl was applied on bacteria and found effective result.

[Show abstract][Hide abstract] ABSTRACT: An intervention study was carried out in Paediatric wards for a period of one year from January 2003 to December 2003 to determine the efficacy and safety of azithromycin in the treatment of uncomplicated childhood typhoid fever. A total of 50 cases were enrolled in the study. The inclusion criteria of the cases were: documented fever for more than 7 days plus two or more of the following clinical features: toxic appearance, abdominal tenderness, hepatomegaly, splenomegaly, diarrhoea, constipation and coated tongue plus positive Widal test and/or blood culture positivity. Patients who had complication like gastrointestinal tract (GIT) haemorrhage; intestinal perforation and/or shock were excluded from the study. Data were collected in a structured questionnaire. Azithromycin was given at a dose of 10mg/kg /day for a period of 07 days. The time to defervescence was 3.82+/-1.49 days. The minimum defervescence time was 02 days and maximum was 07 days. Clinical cure rate was 94%. No serious adverse effect was noted related to azithromycin therapy except nausea, vomiting, and jaundice. Prior treatment with antibiotics did not affect defervescence time (P>0.05). Pre-treatment febrile period has got positive and linear correlation with clinical response (r = +0.593). It was found that once daily administration of oral azithromycin for seven days in the treatment of uncomplicated typhoid fever was effective and reasonably safe.
[Show abstract][Hide abstract] ABSTRACT: Effect of different combinations of nitrogen (N), phosphorus (P) and potassium (K) on six characters namely Root Length (RL), Root Fresh Weight (FRW), Root Volume (RV), Nodule Number (NN), Nodule Weight (NW) and Pod Fresh Weight (PFW) were studied in three lines such as Line-2, Line-16 and Line-18 of blackgram. Analysis of variance showed that all the three lines are different from each other for each of the characters. Factorial analysis showed that N and P after 15 days of sowing, N and K after 30 days of sowing, NPK after 60 days of sowing and P, NP and NK after 75 days of sowing had significant effect on root length. N and NK after 30 and 90 days of sowing and N after 45 and 75 days of sowing had significant effect on root fresh weight. For root volume, N after 45 and 75 days of sowing and N and NK after 90 days of sowing had significant effect. N after 15 days of sowing, PK after 30 days of sowing, P after 45 days of sowing, K and NP after 60 days of sowing, K after 75 days of sowing and NK after 90 days of sowing found to be significantly effective for nodule number. The character nodule weight also affected by K, NP and NK after 15 days of sowing, by P after 30 days of sowing, by N, P, K, PK and NPK after 60 days of sowing and by P, NP and PK after 90 days of sowing. Only P found to be significantly effective for pod fresh weight at an age of 75 days.
