The efficacy and effect of spirulina: anti-radiation damage, oral administration of spirulina to mice before and after radiation irradiation can improve the survival rate of mice. Observation of sensitive organs of irradiated animals shows that spirulina can illuminate mice. Thymus weight and bone marrow DNA content were higher than the control group, indicating that Spirulina has protective effects on immune organs and hematopoietic tissues.

The efficacy and role of spirulina


1. Anti-radiation damage


Oral administration of spirulina to mice before and after radiation exposure can increase the survival rate of mice. The effective dose is 3.75-15 mg (156-625 mg/kg body weight, 2-5 times of taking). Spirulina was administered 3 times, and on the 9th day after 7.5 Gy irradiation, observation of sensitive organs of irradiated animals showed that spirulina could increase the thymus weight and bone marrow DNA content of irradiated mice compared with the control group, indicating that Spirulina It has protective effects on immune organs and hematopoietic tissues, which may be one of the mechanisms of spirulina's resistance to radiation damage.


2, antibacterial effect


Spirulina platensis has a bacteriostatic effect on Gram-positive bacteria. The ethanol extract of Spirulina platensis, which contains lipids and triterpenoids, has the strongest antibacterial activity, and the sterol-containing extract also has antibacterial effect, but the effect is better. weak. Spirulina platensis has no inhibitory effect on Gram-negative bacteria.

3, anti-cancer effect


Spirulina inhibited the formation of large intestine degeneration crypts in NIH mice and standard deviation rats induced by short-term injection and long-term multiple injections of 1,2-dimethylhydrazine. Spirulina polysaccharide has a significant inhibition rate on ascites-type hepatocarcinoma cells in the treatment group, 54.0% in the treatment group and 91.4% in the control group. The inhibition of DNA, RNA and protein in cancer cells is enhanced with the prolongation of the action time.

4. The role of the immune system


Spirulina polysaccharide can increase the serum hemolysin in mice by 39.5%-98.0%, the phagocytic rate of peritoneal macrophages by 32.5%-51.5%, the phagocytic index by 0.9-1.8 times, and the number of T lymphocytes by 46.8%-87.7%. The spleen white pulp lymphocytes are densely arranged, the macrophages in the red pulp are significantly increased, and the acid alpha-naphthyl acetate esterase (ANAE) positive lymphocytes are increased by 7.3%-12.8%.


5, lower cholesterol


Thirty males with high cholesterol and mild hyperlipidemia were divided into two groups. Group A received 4.2 g of spirulina daily for 8 weeks, and serum total cholesterol decreased from 6.3 mmol/L (244 mg/dl) within 4 weeks. To 6.1 mmol/L (233 mg/dl), the drop was 4.5%. Group B stopped for 4 weeks, and the total serum cholesterol decreased, and then returned to the original level. Low-density lipoprotein cholesterol was significantly reduced by 6.1% in 4 weeks, and people with high cholesterol levels had a greater decrease in serum cholesterol.

6, the protection of the stomach


Spirulina platensis 250-500mg/kg can significantly protect the experimental rat gastric ulcer model of indomethacin (indomethacin) and absolute ethanol; it can reduce the occurrence of ulceration model of pylorus ligation rat Rate and reduction of ulcer number, also have a certain inhibitory effect on gastric juice secretion; can accelerate the healing of gastric ulcer in chronic acetic acid type rats
