What this work is about, in plain words
How the biomass of the marine cyanobacterium Leptolyngbya cf. ectocarpi acts on mice with experimental liver damage and intestinal inflammation. According to the authors, in liver damage liver enzymes and bilirubin decreased.
Toxic liver damage and inflammatory bowel disease are studied using animal models. The authors tested how such models are affected by biomass of the marine cyanobacterium Leptolyngbya cf. ectocarpi grown in a photobioreactor at the facilities of sole proprietor T. A. Nevskaya.
A 5 % suspension and an extract were prepared from wet biomass. Liver damage was induced with ethanol in male C57Bl/6 mice or with paracetamol in females, and intestinal inflammation with dextran sulfate sodium in CD-1 mice; each substance was given into the stomach for five days. The suspension or extract was given 7 days before the start or 30 minutes after the damaging substance. In the intestinal model, the drugs cyclophosphamide and prednisolone were used for comparison. White blood cells, liver enzymes, bilirubin, and the structure of the liver and intestine under the microscope were assessed.
According to the authors, in both liver damage models the suspension and extract reduced liver enzyme activity and bilirubin levels. The white blood cell count decreased in alcohol-induced damage and intestinal inflammation and increased in paracetamol-induced damage. Changes in the structure of the liver and intestine were mixed: the authors assess some as favorable and some as unfavorable, such as a reduction in the number of protective cells in the intestinal lining.
Limitations. Small groups, a short period; the authors themselves write that the models did not cause pronounced tissue damage and that the effect requires further study and a search for the active substance. A study in mice; this is not a basis for conclusions about treating people.
