Role of Seaweeds in Drug Induced Nephrotoxicity

Kidney is an important organ which is necessary for the body to perform various important functions which include blood purification, expelling metabolic wastes and managing water and electrolytes balance in the body. In this era of modern science, many synthetic drugs are used on patients to examine their therapeutic properties. Unfortunately, some drugs cause negative effects resulting in renal damage. Drug induced nephrotoxicity results in serious clinical syndromes, such as chronic kidney disease (CKD) and acute kidney injury (AKI). Synthetic drugs not only cure diseases but also cause some side effects in the human body. Instead of looking for synthetic drugs to cure diseases, it is necessary to consider natural drugs that maximize side effects of synthetic drugs and reduce therapeutic consequences with the most effective and dynamic healing effects. Research and utilization of marine algae have increased markedly from the last several decades. Seaweeds have also been used as drugs or drug sources over a large number of years going back into folk medicine. Since consumption of seaweeds as human food or animal feeds is increasing rapidly. In the current review, we have summarized the information regarding the drugs which cause nephrotoxicity and marine algae as seaweeds used for the treatment of nephrotoxicity.

Phytochemical and Potential Properties of Seaweeds and Their Recent Applications: A Review.

Since ancient times, seaweeds have been employed as source of highly bioactive secondary metabolites that could act as key medicinal components. Furthermore, research into the biological activity of certain seaweed compounds has progressed significantly, with an emphasis on their composition and application for human and animal nutrition. Seaweeds have many uses: they are consumed as fodder, and have been used in medicines, cosmetics, energy, fertilizers, and industrial agar and alginate biosynthesis. The beneficial effects of seaweed are mostly due to the presence of minerals, vitamins, phenols, polysaccharides, and sterols, as well as several other bioactive compounds. These compounds seem to have antioxidant, anti-inflammatory, anti-cancer, antimicrobial, and anti-diabetic activities. Recent advances and limitations for seaweed bioactive as a nutraceutical in terms of bioavailability are explored in order to better comprehend their therapeutic development. To further understand the mechanism of action of seaweed chemicals, more research is needed as is an investigation into their potential usage in pharmaceutical companies and other applications, with the ultimate objective of developing sustainable and healthier products. The objective of this review is to collect information about the role of seaweeds on nutritional, pharmacological, industrial, and biochemical applications, as well as their impact on human health.

Microbiological Food Safety of Seaweeds

The use of seaweeds in the human diet has a long history in Asia and has now been increasing also in the western world. Concurrent with this trend, there is a corresponding increase in cultivation and harvesting for commercial production. Edible seaweed is a heterogenous product category including species within the green, red, and brown macroalgae. Moreover, the species are utilized on their own or in combinatorial food products, eaten fresh or processed by a variety of technologies. The present review summarizes available literature with respect to microbiological food safety and quality of seaweed food products, including processing and other factors controlling these parameters, and emerging trends to improve on the safety, utilization, quality, and storability of seaweeds. The over- or misuse of antimicrobials and the concurrent development of antimicrobial resistance (AMR) in bacteria is a current worldwide health concern. The role of seaweeds in the development of AMR and the spread of antimicrobial resistance genes is an underexplored field of research and is discussed in that context. Legislation and guidelines relevant to edible seaweed are also discussed.

Role of seaweeds in neutralizing the impact of seawater acidification- A laboratory study with beached shells of certain bivalves and spines of a sea urchin

Ocean acidification is one of the major impacts of climate change in sea which is manifested by the decrease in hydrogen ion concentration (pH) of seawater mainly due to increased uptake of CO2 and reduction in carbonate ions. This is a report on the dissolution rate of dead shells of four marine bivalves and spines of a sea urchin when treated with different levels of CO2 dissolved in seawater for 48 hours which was measured gravimetrically. Dissolution of dead shells expressed as reduction in shell weight was directly proportional to the concentration of dissolved CO2. Live thallus of green seaweed Chaetomorpha antennina did reduce the magnitude of dissolution rates (P<0.05) of all the shells and spines considerably as well as the change in pH of ambient seawater due to the addition of CO2. The remedial property of seaweeds was more effective at lower concentrations of dissolved CO2. The induced change in pH was restored by green seaweed only at concentrations above 250 ppm. Although we noticed strong impact of dissolved CO2 on the dead shells of Mactrinula plicataria even at 100 ppm level, the remedial action by the green seaweed was maximum in Siliqua radiata followed by Perna viridis. Results of this laboratory study shows the positive role of seaweeds in neutralizing the acidification impacts.

Studies on the littoral seaweed epifauna of St Croix Island. 3.Gelidium pristoides(Rhodophyta) and its epifauna

The distribution of Gelidium pristoides, a commercially important seaweed in South Africa, was investigated on St Croix Island in Algoa Bay. Total area of the midlittoral G. pristoides belt was 4241 m 2 and total summer standing crop of this perennial seaweed was 265 kg (dry mass). Monthly numerical composition of G. pristoides epifauna at three sites on St Croix is presented and discussed. Nematodes dominated the epifauna throughout the year with harpacticoids the second most abundant taxon. The presence of nauplius, annelid and Diptera larvae as well as juvenile amphipods and molluscs in the epifauna indicates the role of seaweeds as nursery areas for littoral fauna. G. pristoides epifauna averaged 1,77 x 10 5 animals m -2 . Total summer standing stock of G. pristoides epifauna on St Croix was determined by two methods which yielded 6,4 x 10 8 and 7,3 x 10 8 animals respectively.
