Callus and suspension cells culture of Kaempferia parviflora was successfully established. Meristematic shoots can be used for utilization of plant cell biosynthetic capabilities for obtaining useful products from valuable medicinal plant to meet out the pharmaceutical demand and also for studying the metabolism. The medium containing combination of 0.2 mg/L 2,4-dichlorophenoxyacetic acid (2,4-D) and 0.2 mg/L napthyleneacetic acid (NAA) promoted the highest callus induction at 20%. Transferring the initiated callus on the medium with 1 mg/L 2,4-D enhanced the proliferation rate up to maximum fresh weight of 6.71 gm. Growth curve of cultured cells revealed that the cells continued to grow until 50 days of culture and showed the highest peak (fresh weight) at 40 days in all different initial weight tested ( 0.2, 0.5 and 1.0 gram). Isolated embryogenic callus was found to produce the highest in weight when suspended in liquid medium supplemented with 1 mg/L 2,4-D at 110 rpm resulted 13.5 gram fresh weight and 1080 mg dry weight.

多数研究犍陀罗艺术的学者认为锡克里（Sikn）是拉合尔博物馆收减的禁食悉达多（Siddhartha）像和其它一些著名雕塑的发现地。但是关于这些出士文物及艺术制品还有更多的信息应该为人所知。考古调查局总长詹姆斯·伯吉斯（James Burgess）宣称锡克里是犍陀罗地区第一处经过科学发掘的遗址，而且出土了大量的雕塑，其中许多为质量精湛之作。这些雕塑被搜集到一起并被送到拉合尔中央博物馆——然而，令人遗憾的是，这些雕塑一直被严重地忽视了。

Background: Transurethral resection of prostate (TURP) is the gold standard in the surgical treatment of symptomatic benign prostatic hyperplasia (BPH). Blood loss is one of the most common complications of TURP. Objective: To evaluate the effect of preoperative dutasteride on bleeding related to TURP in patients with BPH. Materials and Methods: This prospective interventional study was done in the department of urology, Dhaka Medical College Hospital, Dhaka, Bangladesh during the period of July 2016 to June 2017. A total of 70 cases of BPH planned for TURP were included in this study according to the statistical calculation. Patients were randomly allocated to control group A (TURP without dutasteride) and dutasteride group B (TURP with dutasteride). Each group consisted of 35 patients. Group B patients were treated with dutasteride 0.5 mg/day for 4 weeks before TURP. The main outcome of blood loss was evaluated in terms of reduction in serum hemoglobin (Hb) and hematocrit (Hct) levels, which were measured before and 24 hours after surgery. Data were analyzed and compared by statistical tests. Results: Comparison of outcome between groups shows that there was a significant difference in term of pre-post operative change of hemoglobin and hematocrit levels in the control group A compared to the dutasteride group B (Hb = 2.96 ± 0.80 gm/dl vs. 1.81 ± 0.71 gm/dl, respectively, p = 0.001;Hct = 11.20% ± 2.12% vs. 6.07% ± 2.02%, respectively, p = 0.02). A significant lower mean blood loss was observed in the dutasteride group compared to the control group. Conclusion: Preoperative dutasteride therapy reduces blood loss related to TURP in patients with BPH. This therapy can be practiced to reduce surgical bleeding associated with TURP.

Background: Lupus nephritis (LN) is one of the most common presentations of Systemic lupus erythematosus (SLE). Cyclophosphamide is one of the key immunosuppressive agents for the management of LN. Leflunomide is an isoxazole immunomodulatory agent has been shown to be safe, well tolerated and effective in SLE and LN. Objective: To evaluate the outcome of leflunomide in the treatment of proliferative lupus nephritis compared to cyclophosphamide. Method: This randomized clinical trial was held in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from July 2017 to August 2019. A total of 66 patients of proliferative lupus nephritis who need induction therapy were enrolled in this study. Leflunomide 100 mg/day for consecutive 3 days followed by 0.5 mg/kg/day in divided dose was given in experimental group (n = 32) and intravenous cyclophosphamide 0.5 gm/m2 of body surface area monthly pulse was given in control group (n = 34). All study patients have received prednisolone and hydroxychloroquine according to KDIGO guideline then followed up monthly for 6 months. Outcomes were measured at 6th month by renal function [S. Creatinine, 24 hours urinary total protein (24-hr UTP)], changes in SELENA-SLEDAI score, anti-ds DNA level, serum complement levels (serum C3 & C4), remission (complete/partial) and adverse drug responses. Result: In experimental group, remission occurred in 18 (56.3%) patients and no remission in 14 (43.7%) patients. In control group, remission occurred in 24 (70.6%) patients and no remission in 10 (29.4%) patients. Adverse effects in experimental group were: elevated ALT (6.3%), hypertension (12.5%), infection (6.3%) and amenorrhea (12.5%). In control group, adverse effects were mainly leucopenia (5.9%), infection (17.7%) and amenorrhea (29.4%). Intergroup analysis for treatment responses and adverse effects showed no significant difference (p > 0.05). Concl

Background: Diabetes mellitus (DM) is the leading cause of end stage renal disease (ESRD) worldwide. Although DM with proteinuria is the ultimate result of diabetic nephropathy (DN), a wide spectrum of non-diabetic renal diseases (NDRD) can occur in such patients. Objective: To observe the frequency and histological pattern of NDRD in diabetic patients with proteinuria and to explore their association with clinical and laboratory parameters. Methods: This cross-sectional study was conducted in the Department of Nephrology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from April 2016 to September 2017. In this study a total of 38 cases of DM with proteinuria (>1 gm/24-hour) were selected purposively. Renal biopsy was done in all patients. Based on histological findings they were categorized into two groups;Group 1 with NDRD and Group II with DN. Their clinical and laboratory parameters were analyzed and compared. Results: Among the total study subjects, 21 (55.3%) were male and 17 (44.7%) were female, mean (±SD) age 43.45 ± 9.99 years in the NDRD group and 41.57 ± 9.50 years in the DN group. Thirty one cases (81.6%) out of thirty eight had NDRD and seven (18.4%) cases had isolated DN;therefore more than two third cases had NDRD. Duration of DM was found to be significantly shorter (p = 0.004) in the NDRD group. Diabetic retinopathy was present in 12.9% cases in NDRD group vs. 57.1% cases in DN group (p = 0.025). Frequency of microscopic hematuria was significantly higher (90.3%) in NDRD patients (p = 0.002). Conclusion: The frequency of NDRD in type 2 diabetic patients other than diabetic nephropathy is relatively high. Membrano proliferative glomeru-lonephritis and membranous nephropathy are more common in NDRD. Absence of diabetic retinopathy, presence of hematuria and shorter duration of DM are markers associated with NDRD in type 2 DM, which are important indicators for renal biopsy in diabetic patients with proteinuria.
