For the first time in the Andizhan region of the Republic of Uzbekistan, it was found that high-altitude algae can be used by the method of biological treatment of municipal wastewater. the results of the study, we used biological treatment of high-water plant species such as pistia (Pistia stratiotes), Euchornia crassipes Solms, azolla (Azolla coroliniana Willd), with the observations of the dynamics of rapid growth and development at high concentrations. We developed a Pistia stratiotes, which is scientifically grounded in improvement, and was recommended for reproduction under laboratory conditions.</p> Ch. H. Kuchkarova U. S.

About 12-15 million affected persons are in Sub-Sahara Africa with Nigeria bearing the highest burden of people living with sickle cell disease. SCD is a disease characterized as an autosomal, recessive, heterogeneous, and a monogenetic disorder caused by an A-to-T point mutation in the β-globin gene responsible for the production of abnormal hemoglobin S (HbS), which polymerizes in the deoxygenated state and results in the sickling of erythrocytes.&nbsp; Haemoglobin variants are mutant forms of haemoglobin in a population usually occurring as a result of genetic changes in specific genes, or globins that causes change on alterations in the amino acid. They could affect the structure, behavior, the production rate and the stability of the specific gene. Well-known haemoglobin variants such as sick-cell anaemia are responsible for diseases and are considered haemoglobinopathies. Other variants cause no detectable pathology and are thus considered as non-pathological variants.</p> <p><strong>Aim: </strong>The study is aimed at evaluating the burden of sickle cell disease and other haemoglobin variants in Calabar, South-South Nigeria.</p> <p><strong>Methods: </strong>This is a retrospective study done at the haematology laboratory of University of Calabar Teaching Hospital, Calabar. Cellulose acetate electrophoresis at alkaline pH was used for the evaluation of haemoglobinopathies. The data were entered into Microsoft Excel 2016 spreadsheet and analysed with the IBM SPSS Version 22. Data were summarized into percentage of different phenotypes.</p> <p><strong>Results: </strong>Results of the total 3648 haemoglobin electrophoresis recorded, 1368 (37.50%) were male while the remaining 2280 (62.5%) females given a male to female ratio of 1:1.7. Five haemoglobin phenotypes were identified as HbAA, HbAS, HbAC, HbSC and HbSS. The overall average values of their prevalence were HbAA 64.78%, HbAS 32.62%, HbSS 2.14%, HbAC 0.33%, HbSC 0.14%. Thus, the prevalence of SCD (Prevalence of HbSS+HbSC) was 2.28%. The highest proportion of SCD was observed in 2011 with least in 2016 and 2017 respectively.</p> <p><strong>Conclusion: </strong>The prevalence of SCD and other haemoglobin variants in Calabar is similar to that of the national prevalence rate. There is need for continuous enlightenment and premarital counselling on the pattern of inheritance of SCD most especially with the increased burden of sickle traits in the environment has reported in this study.</p> Akaba Kingsley Ofem Enang Ofonime Essien Annette Legogie Omini Cletus Olukayode Oshatuyi ##submission.copyrightStatement## 2019-11-13 2019-11-13 1 6 10.9734/arrb/2019/v33i530132
