Total IgE (tIgE) levels show wide variations depending on various factors, such as age, sex, ethnicity, and geographic area. This study set out to quantitatively determine the serum tIgE levels in Bangladeshi population who were clinically suspected cases of allergic diseases and to find out the association of tIgE level with their age and gender. This cross-sectional descriptive exploratory study was conducted at Biomed Diagnostics Laboratory, Panthapath, Dhaka, from March 2021-September 2021. A total of 402 blood samples were collected from clinically suspected cases of allergic diseases. Quantitative detection of tIgE in serum was done by Immunoblot assay manufactured by Proteome Tech Inc. (PROTIATM Allergy-Q64S panel). Among 402 subjects, a wide variation of tIgE levels ranging from 5 to 2000 IU/ml was found but majority of the study population (30.35%) showed tIgE levels within the range of 201 - 350 IU/ml. The study population aging 1 - 10 years showed highest frequency (23.63%) in tIgE concentrations and the mean tIgE level exhibited a declining tendency with an increase in age. Depending on gender there was no difference in tIgE levels. Determination of tIgE level is imperative for screening allergic diseases. The present study enlightened the distribution of tIgE levels and suggested that among Bangladeshi subjects irrespective of gender there is an inverse relationship between tIgE level and age.展开更多

Jabal Akhdar receives more rainfall(300-400 mm) when compared to the desert plains. In the last few years, this region had undergone enormous changes due to rapid development. The resident and transient populations have increased and their activities exert severe stress on the water resources. There are 24 retention reservoirs in the area, but most are eutrophic and the nutrient loading is due to input of animal fecal matter via surface run-off. As expected, these waters contaminated with coliform bacteria and some have pathogenic Escherichia coli. Drinking water needs of all the villages met by groundwater extraction. Because of poor quality, the surface water in the reservoirs is under-utilized. A low-cost lowmaintenance treatment system designed, constructed and operated in one village to clean the reservoir water for non-drinking human use. The treatment unit improved the water quality parameters. A survey among the adult male population of the village showed their eagerness to adopt this system and use the treated reservoir water for uses other than agriculture. Establishment of these treatment units in other villages should reduce the pressures on groundwater extraction.展开更多
