The study was carried out in order to assess the impact of the various pollutants of textile dyeing effluents on the surface water quality of the industrial area inside Dhaka-Narayanganj-Demra (D.N.D) embankment, Narayanganj. Physicochemical parameters such as TSS, TDS, DO, pH, EC, Turbidity, BOD, COD, anionic parameters such as F-, Cl-, NO2 -, NO3 -, SO4 - and PO4 3- and heavy metals such as Pb, Zn, Cd and Cu of the samples were investigated by using various techniques. The results showed that, textile dyeing industries inside D.N.D embankment area discharges effluents composed of various physicochemical and anionic pollutants at considerably higher level compared to pollution limit. Further, the surface water of the D.N.D channel, ponds and lakes around the studied textile dyeing industries also contain various physicochemical and anionic pollutants at intolerable limit. A significant correlation was also observed among some important water parameters of the effluents and surface ...

Introduction: Androgenetic alopecia (AGA) is an androgen-mediated condition that is characterized by a progressive decline in visible scalp hair density. Genetically predisposed hair follicles are the target of dihydrotestosterone (DHT), which leads to the progressive miniaturization of hair follicles and hair thinning. Dutasteride inhibits conversion of testosterone to dihydrotestosterone, which significantly improves hair growth. Objective: To assess the outcome of dutasteride in androgenic alopecia. Methods: This study was carried out at Dermatology and Venereology Department, Enam Medical College Hospital, Savar, Dhaka, Bangladesh from January2022 to July 2022. From the outpatient clinic fifty (50) patients were recruited who fulfilled the inclusion and exclusion criteria. Dermatologist observe every patients hair changes before, during &after treatment with dutasteride for 24 week. Results: Out Of the 50 patients, 60% patients were female. 40% patients noticed hair loss first a...

The effective dose of ? radiation on chitosan for mango preservation was studies in this work. The 2% chitosan solution was irradiated with at various total doses (50-200 kGy). The mature green mangoes were soaked in un-irradiated and irradiated chitosan solutions and then they were stored at normal room temperature. The percentage of weight loss, color change and percentage of spoilage were observed for 15 days in control, un-irradiated and irradiated chitosan coated mangoes. The overall results showed the superiority of 50 kGy and 100 kGy irradiated chitosan in extending shelf life of mango as comared to control, un-irradiated and 120 kGy to 200 kGy irradiated chitosan.

A small part of the palaeo beach formation extending along the south-eastern fringe of Bangladesh was selected as study area. The sandy beach formation, enriched with heavy mineral sands containing ²³²Th-bearing monazite, is covered by a thin layer of top soil. Activity concentrations of natural and artificial radionuclides (²³⁸U, ²²⁶Ra, ²³²Th, ⁴⁰K and ¹³⁷Cs), outdoor and indoor annual effective dose rates and the radiation hazard indices were determined in the soil. The radionuclides, investigated by direct gamma-ray spectrometry using HPGe detector, showed that mean activity concentrations of ²²⁶Ra, ²³⁸U, ²³²Th, ⁴⁰K and ¹³⁷Cs in soils were 254.53 ± 6.66, 193.95 ± 7.23, 362.18 ± 6.45, 135.79 ± 24.63 and 2.21 ± 0.49 Bq kg⁻¹ respectively. The mean value of radium equivalent activity, external and internal hazards, outdoor absorbed dose rate and total annual effective dose rate were 783.24 Bq Kg⁻¹, 2.12 and 2.80, 354.32 nGyh⁻¹ and 2.52 mSv y⁻¹, respectively, which exceed the average worldwide limit and may pose a radiological threat to inhabitants.

Ranitidine is a H2receptor blocker, which is widely used for the treatment of peptic ulcer disease. Present was designed to assess the therapeutic properties of different branded ranitidine hydrochloride tablets available in retail pharmacies of Bangladesh. Ranitidine HCl tablets manufactured by five different brands following USP specifications were collected from local retail Pharmacy located in Dhaka. Various parameters such as weight variation, thickness, hardness, disintegration, dissolution, potency etc. were analyzed according to the official (BP/USP) pharmacopoeia methods to evaluate their quality. The result showed that four brands of Ranitidine HCl tablets complied USP specification of potency and the remaining one was more potent. Four brands showed a good result for weight variation, hardness, disintegration time and dissolution rate. One brand of tablets showed minor deviation in dissolution rate as compared to USP specification. It is evident from the study that most o...
