Abstract
Introduction: Alginic acid, a polysaccharide is one of the important phytochemical ingredients of brown algae, Turbinaria conoides (J. Agardh) Kutzing. T. conoides has been studied for various pharmacological activities, yet no toxicological information found in the literature therefore, preset study aimed at extraction and isolation of alginic acid and to assess the safety profile through acute and sub acute toxicity study in both male and female rats. Materials and Methods: Alginic acid was characterized through Fourier transform infrared spectroscopy, thermo gravimetric and differential scanning calorimetric analysis. In acute toxicity study, female rats received 2000 mg/kg of isolated product, at a single dose on oral administration. In subacute toxicity study, both male and female rats were given with 100, 200 and 400 mg/kg of the isolated product, orally, for a period of 28 days consecutively and behavioral changes, hematological, biochemical and histopathological investigations were verified. Results and Discussion: In acute toxicity study, no morbidity or mortality was reported with alginic acid treated animals at a dose of 2000 mg/kg. In sub-acute toxicity study, there were no treatment related abnormalities observed in hematological and biochemical parameters except, decreased red blood cell count (400 mg/kg); increased platelets (200 mg/kg) in female rats and increased levels of liver parameters (serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, gamma glutaryl transferase); lipid parameters (total cholesterol, triglycerides and blood glucose) in both male and female rats. Histopathology studies revealed a slight infiltration of cells and congestion in blood vessels in the liver; congestion of alveolar tissue in lungs with 400 mg/kg treated animals. No behavioural changes observed. Conclusion: From the obtained results it is indicated that the oral administration of alginic acid (active principle of T. conoides) did not produce any significant adverse effects in rats of both the sex. Hence, alginic acid was considered as safe to use for further therapeutic purpose.

Abstract
Marine environment is a home to a very wide diversity of flora and fauna, which includes an array of genetically diverse coastline and under seawater plant species, animal species, microbial species, their habitats, ecosystems, and supporting ecological processes. The Earth is home to an estimated 10 million species, of which a large chunk belongs to marine environment. Marine plants are a store house of a variety of antimicrobial compounds like classes of marine flavonoids—flavones and flavonols, terpenoids, alkaloids, peptides, carbohydrates, fatty acids, polyketides, polysaccharides, phenolic compounds, and steroids. Lot of research today is directed toward marine species, which have proved to be a potent source of structurally widely diverse and yet highly bioactive secondary metabolites. Varied species of phylum Porifera, algae including diatoms, Chlorophyta, Euglenophyta, Dinoflagellata, Chrysophyta, cyanobacteria, Rhodophyta, and Phaeophyta, bacteria, fungi, and weeds have been exploited by mankind for their inherent indigenous biological antimicrobial compounds, produced under the extreme stressful underwater conditions of temperature, atmospheric pressure, light, and nutrition. The present study aims at presenting a brief review of bioactive marine compounds possessing antimicrobial potency.

Sodium alginate potentiates antioxidants, cryoprotection and antibacterial activities of egg yolk extender during semen cryopreservation in buffalo. Anim Reprod Sci 2019; 209:106166. [PMID: 31514937 DOI: 10.1016/j.anireprosci.2019.106166] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2019] [Revised: 07/22/2019] [Accepted: 08/15/2019] [Indexed: 12/24/2022]
Abstract
The study was conducted to determine effects of sodium alginate on sperm during cryopreservation. Each ejaculate (n = 20) of five buffalo bulls (3-5 years) were divided into six equal fractions and diluted using egg yolk based extender supplemented with different concentrations of sodium alginate and cryopreserved. Frozen-thawed semen samples were evaluated using the CASA, hypo-osmotic swelling test, cervical mucus penetration capacity test, and chlortetracycline fluorescence assay (CTC). Phosphorylation of tyrosine containing proteins and malondialdehyde concentration of sperm membrane were evaluated using immunoblotting and thiobarbituric acid reactive substance assay respectively. The semen extender's anioxidative capacities were estimated by conducting 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays, metal chelating capacity by assessing ferrozine and antibacterial capacity using agar plate methods. Supplementation of sodium alginate in extender improved sperm longevity, plasma membrane integrity as well as capacity to transit through the cervical mucus. Supplementation of extender with sodium alginate minimises the phase transition of sperm membranes and phosphorylation of tyrosine containing proteins during cryopreservation. Malondialdehyde concentration of sperm was less in sodium alginate-treated sperm as compared with control samples. The results indicated that sodium alginate increased antioxidant capacity of semen extender. Supplementation with sodium alginate also improved the metal chelating capacity and antibacterial properties of the extender. In conclusion, supplementation of extender with sodium alginate enhances free radical scavenging, metal reduction and chelating capacities to protect sperm during cryopreservation.

Abstract
The oceans harbor a great diversity of organisms, and have been recognized as an important source of new compounds with nutritional and therapeutic potential. Among these compounds, carbohydrate-based compounds are of particular interest because they exhibit numerous biological functions associated with their chemical diversity. This gives rise to new substances for the development of bioactive products. Many are the known applications of substances with glycosidic domains obtained from marine species. This review covers the structural properties and the current findings on the antioxidant, anti-inflammatory, anticoagulant, antitumor and antimicrobial activities of medium and high molecular-weight carbohydrates or glycosylated compounds extracted from various marine organisms.
