A team of scientists from the National School of Biological Sciences (ENCB); National Polytechnic Institute (IPN) found the protective effects of spirulina microalgae and some cyanobacteria against kidney and liver damage caused by oxidative stress.
According to the experts who participated in this investigation-- Edgar Cano Europa, Adelaida Hernández García, Rocío Ortiz Butrón, Margarita Franco Colín and Vanessa Blas Valdivia-- oxidative stress occurs when there is an imbalance between the reactive oxygen production and the body ability to eliminate it.
The accumulation of heavy metals is caused by the ingestion of food, the environmental contamination and the direct exposure to these elements.
According to investigators, when heavy metal contamination occurs, oxidative stress harms the kidneys and the liver.
These organs may have edema, atrophy, cell damage and hyperchromasia (the nuclear staining is darker and the cellular component distribution is lost).
The research consisted of the administration of microalgae spirulina to a rodent intragastrically through a small tube, 30 minutes after mercury poisoning. During the following five days microalgae was given and on the sixth day the animal was killed.
"Fortunately, we found out that there was no damage, even in some animals given lethal doses of mercury it is surprising that it avoids mortality," researchers pointed out.
The team of scientists is evaluating the possibility of communicating with experts from the Center for Research in Applied Biotechnology (IBC), Tlaxcala Unit, to provide greater volumes of the product as about 40 liters of microalgae are needed to produce 68 grams of powder.
"To reach the benefits of the nutraceutical product that we are planning to create, it is necessary to grade the product, which can only be achieved through collaboration," added the researcher.
Colin Franco said microalga has some substances that favorably influence the body.
To prevent oxidative stress and maintain glucose and cholesterol levels stable, the intake of a milligram of spirulina algae is recommended as food supplements, the Journal Mex informed.
