Background: Depression is associated with stressful condition which may cause kidney damage. Oyster mushroom (plurotus florida) may have free radical scavenging activity thereby can be used for the prevention and treatment for kidney damage. Objective: to observe the effect of oyster mushroom (plurotus florida) on kidney in restraint stress induced depressed rats. Methods: This experimental study was conducted from July 2012 to June 2013 in the Department of Physiology, Sir Salimullah Medical College( SSMC), Mitford, Dhaka. Thirty Wister albino male rats, aged 90 to 100 days, weighing 150 to 180g (initial body weight) were used in the present study. Then they were divided into Group I (Control group, without mushroom n=20) and Group II (Experimental group, depressed rats supplemented with mushroom n=10). Control group without mushroom again subdivided into Group Ia,( baseline control n=10) and Group Ib (depressed control n=10) . All groups of animals were received basal diet for 28 consecutive days started from the 1 st day of the study period. Group Ib (depressed control) and group II (depressed mushroom supplemented) were housed under controlled condition in rat immobilizer (made up of steel wire, measuring 9´´x2.75´´ of light weight) for 6 hour/day for 28 days for the development of stress induced depression. In addition, only group II received oyster mushroom extract (200 mg/kg body weight, orally) for the same period. One rat of Group Ib (depressed control) was expired after 10 days for unknown cause. All 29 rats were sacrificed on day 30. Then blood sample and kidneys specimen were collected. Initial (initial bw ) and final body weights (final bw) were measured. Then estimation of blood glucose and serum urea levels were done by standard laboratory technique. Histology of kidney was done by standard laboratory procedure. Statistical analysis was done by using SPSS windows Version -16. One way ANOVA and Bonferroni tests were done as applicable. Results: In this study blood glucose level and serum urea level was significantly higher and abnormal histological structure was found in stress induced depressed rats. After taking mushroom extract for 28 days all the parameters were improved. Conclusion: From this study it can be concluded that oyster mushroom(Pleurotus florida) which is excellent edible and nutritious, may have renoprotective effect.

Hysterectomy is the commonest major surgical procedure in Gynaecology & usually performed to improve quality of life rather than to cure life-threatening conditions. The rates differ between countries depending on differences in morbidity, health economical aspects, traditions and attitudes. This retrospective observational study was carried out from 2001-2010 & included all cases of abdominal hysterectomy done for benign and non emergency conditions in the department of Obstetrics & Gynaecology, Holy Family Red Crescent Medical College and Hospital, Dhaka with the intention to assess the proportion and the indications of total abdominal hysterectomy over a 10-year period. Percentage of the total abdominal hysterectomy remained between 50-70% of the total major operations over the decade. Fibroid was found to be the most common indication among the admitted patients (around 36%) with highest percetage in 2006 and 2007 (43% and 46% respectively). Next important indication was dysfunctional uterine bleeding (20%) followed by pelvic inflammatory disease (13%), ovarian mass (5%), endometriosis & adenomyosis (4%) and post menopausal bleeding (2%). The majority of hysterectomies were abdominal and the most common indication was uterine fibroids. The overall rate for hysterectomy remained reasonably stable.Bangladesh Med J. 2015 May; 44 (2): 87-91

This paper aims at empirically studying the impact of some selected bankspecific factors on Islamic banks’ profitability. The data for this study covering a period 2009-2013 is obtained from the annual reports of respective Islamic banks. The statistical tool employed is the technique of linear multiple regression analysis. The data-set used in this study involves eight Islamic banks operating in Bangladesh. Empirical results show that bank-size and deposit have significant negative impact on the return on assets (ROA) which is the proxy for Islamic banks’ profitability, while equity is found to have positive significant impact. However, loan and expense management are found to be insignificant in affecting the profitability of the banks.Journal of Business and Technology (Dhaka) Vol.10(1) 2015; 21-36

A study was conducted to determine the poverty and credit facilities of groundnut producers and profitability and resource use efficiency of groundnut production in the selected char areas of Gaffargaon upazila in Mymensingh district. In this study, 100 respondents were randomly selected from the mentioned upazila. Farmers were classified into three categories on the basis of loan size. Cobb-Douglas production function was used to determine the contribution of factors to groundnut yield. It is evident from the study that per acre net returns were greatly influenced by the use of human labour, animal labour, seeds and insecticides and it was found that they got profit from groundnut cultivation and the undiscounted BCRs (both the variable cost and total cost basis) was estimated at 1.88 in case of all categories of farmers. The mentioned factors were directly or jointly responsible for influencing per acre net returns for groundnut cultivation. Maximum loan money was utilized in family expenditure purpose for meeting their emergency and urgent needs to survive. But their repayment was satisfactory. However some problems were identified (i.e, tips and bribes, delay in providing loan and their poverty) in receiving loan for groundnut cultivation. It appears from the analysis that among three categories of farmers marginal farmers suffered a lot from inadequate supply of credit. The present study suggests that to develop agriculture, to reduce poverty and to increase the productivity of the farmers, both public and private sectors need to give attention on groundnut production in char area for their poverty reduction.J.

Wireless Sensor Networks (WSNs) are playing remarkable contribution in real time decision making by actuating the surroundings of environment. As a consequence, the contemporary agriculture is now using WSNs technology for better crop production, such as irrigation scheduling based on moisture level data sensed by the sensors. Since WSNs are deployed in constraints environments, the life time of sensors is very crucial for normal operation of the networks. In this regard routing protocol is a prime factor for the prolonged life time of sensors. This research focuses the performances analysis of some clustering based routing protocols to select the best routing protocol. Four algorithms are considered, namely Low Energy Adaptive Clustering Hierarchy (LEACH), Threshold Sensitive Energy Efficient sensor Network (TEEN), Stable Election Protocol (SEP) and Energy Aware Multi Hop Multi Path (EAMMH). The simulation is carried out in Matlab framework by using the mathematical models of those algortihms in heterogeneous environment. The performance metrics which are considered are stability period, network lifetime, number of dead nodes per round, number of cluster heads (CH) per round, throughput and average residual energy of node. The experimental results illustrate that TEEN provides greater stable region and lifetime than the others while SEP ensures more througput.

There is a tremendous unmet need to discover more potent and safe drugs for the treatment of Alzheimer's disease (AD). Reduced cholinergic activity and oxidative stress have been recognized as a major contributing factor in the pathogenesis of AD.
