Antitumor Efficacy of Silver Nanoparticles Biosynthe-sized from Marine Red Seaweed Halymenia porphyroides Boergesen on Dalton’s Lymphoma Ascites in Mice

The biosynthesized silver nanoparticles from marine red seaweed Halymenia porphyroides against Dalton’s lymphoma ascites (DLA)-induced tumor inoculation was studied for antitumor activity. The biosynthesized silver nanoparticles from marine red seaweed Halymenia porphyroides were given orally to Swiss albino mice (50 mg/kg/day) for 14 days showed a significant reduction in body weight, packed cell volume, andviable tumor cell count when compared to the mice of the DLA control group.The haematological parameters of the treatment group with biosynthesized silver nanoparticles also exhibited increased haemoglobin, RBCs, Platelets, and decreased WBCs compared to the DLA control group of mice. Similarly, the biochemical parameters like total cholesterol, aspartate amino-transferase (AST), alanine aminotransferase (ALT), triglycerides (TL), and alkaline phosphatase (ALP) of the treatment control group with biosynthesized silver nanoparticles reversed the parameters to normal levels compared to the DLA control group of mice. The antitumor efficacy of the biosynthesized silver nanoparticles from Halymenia porphyroides was confirmed based on the haematological, biochemical, life span, packed cell volume, cell count, and histopathological analysis.
