Selenium Alleviates Carbohydrate Metabolism and Nutrient Composition in Arsenic Stressed Rice Plants

Rice science 2022年第4期29卷 385-396页

This study reported the influence of selenium(Se)on carbohydrate composition and some related enzymes and nutrient compositions of arsenic(As)stressed rice *** plants of cultivar PR126 were grown on soil amended with As in a range of 25-100μmol/kg with and without 0.5 or 1.0 mg/kg *** soluble sugars(TSS)and reducing sugars(RS)increased in leaves of As stressed plants at the tillering and grain filling stages whereas sucrose and starch contents showed the reverse *** supplementation to As stressed plants further increased TSS and RS,and enhanced sucrose phosphate synthase activity in rice leaves,thus improving sucrose content and the tolerance to As stress of the *** alone or in combination with As resulted in lower As accumulation in rice husk and grains,and the highest reduction was observed in Se applied at 1.0 mg/kg compared to the corresponding As treatments *** may limit the accumulations of Na,Mg,K,Ca,Fe,Zn and Mn in rice grains,which are essential for *** application of different combinations of As and Se protected the plants against As and increased the mineral content in rice *** of Se in As treated soil significantly alleviated As stress by enhancing grain yields compared to the corresponding As *** is concluded that Se induced amelioration of the toxic impact of As in rice either by modulating carbohydrate composition and/or nutrient uptake is one of the mechanisms to alleviate As stress in plants.

Selenium Accumulation and Antioxidant Status of Rice Plants Grown on Seleniferous Soil from Northwestern India

引用

Rice science 2014年第6期21卷 327-334页

作者： sucheta sharma Reeti GOYAL Upkar Singh SADANA Department of Biochemistry Punjab Agricultural University Department of Soil Science Punjab Agricultural University

Greenhouse experiment was conducted to investigate selenium accumulation and its antioxidant response in two rice varieties （PR116 and Pusa Basmati 1121） grown on normal and seleniferous soils. The plant growth was reduced at early developmental stages and flowering was delayed by a period of 10 d on seleniferous soil. Selenium accumulation increased by 3-20 and 13-14 folds in leaves, 18 and 3 folds in grains from Pusa Basmati 1121 and PRl16 varieties, respectively. Selenium accumulation in leaves from rice plants grown on seleniferous soil resulted in significant increase in chlorophyll content, hydrogen peroxide, proline, free amino acids, total phenol and tannin contents. Lipid peroxidation levels and peroxidase activities in leaves increased whereas catalase activity showed a reverse trend. It is concluded that selenium accumulation decreased dry matter content in rice during crop development but these plants were able to combat selenium toxicity by inducing alterations in their defense system.

Hypersensitivity Reaction to Misoprostol—A Case Report

引用

International Journal of Clinical Medicine 2012年第3期3卷 223-224页

作者： Monika Madaan Manju Puri Ritu sharma Shubha Sagar Trivedi Lady Hardinge Medical College (LHMC) & Srimati sucheta Kripalini Hospital (SSKH) New Delhi India.

Misoprostol has been used in obstetrics for a number of years in all trimesters of pregnancy. Apart from its side effect of causing congenital malformations in offsprings of users who have unsuccessfully used it as an abortifacient, it is considered a safe drug with few side effects. We here report a case of severe hypersensitivity reaction to misoprostol in a patient where it was used for first trimester abortion in a case of missed abortion.
