Its nutrient content makes it a novel source for both human food and animal feed. However, no research has been done on its food safety or possible toxicity. The toxicological evaluation was carried out on mice for 2-weeks at four distinct dose levels of 2000, 3000, 4000, and 5000 mg/kg bodyweight, according to the criteria of the Organisation for Economic Co-operation and Development (OECD). Bodyweight and clinical indicators showed no substantial toxicological related alterations. Furthermore, no toxicological changes in haematology were observed. When compared to a vehicle control group, serum alanine aminotransferase and creatinine levels did not differ between the experimental groups. In the liver and kidney tissues of mice, no histological and gross abnormalities were found. The relative organ weight of the treatment groups did not differ significantly from that of the vehicle control group. As a result, the LD<sub>50</sub> value for <em>Ducetia japonica</em> is considered to be greater than 5000 mg/kg body weight and no evidence of toxic changes were observed in the present study.</p> Pura Yashung Jharna Chakravorty Copyright (c) 2021 Copyright (c) 2021 The author(s) retains the copyright of this article. 2021-09-02 2021-09-02 12 3 24 29 Potential of Marine Algae in Biosynthesis of Nanoparticles and their Applications <p>Marine algae have been played an important role in human life since 3000 BC, with their nutritional and therapeutic values. In recent years, the role of marine algae in various industrial, agricultural and therapeutic applications have been further enhanced with their ability to biosynthesize nanoparticles. In this work, we tried to shed some light on different traditional and biotechnological applications of marine algae in modern life, particularly their utilization in the wider applications of nanotechnology.</p> Rabaa Algotiml Ali Gab-Alla Roshdi Seoudi Hussein H.
