RESUMO

Objective To observe the influence of polysaccharide from spirulina platensis(PSP) on human embryo lung diploid fibroblastic DNA damage and repair after UV irradiation. Methods After UV irradiation for 30min, the single cell gel electrophoresis(SCGE) was used to investigate the level of DNA damage, the level of DNA damage and repair at 30, 60, 90min were also investigated by SCGE respectively. Results The level of DNA damage induced by UV irradiation was prevented by PSP, and it also promote DNA repair capacity. Conclusion PSP can increase the activity of DNA endonuclease and DNA ligase in dose-de- pendrntly.

RESUMO

Objective: To investigate the anti-inflammatory, bacteriostatic, diuretic, antispasmodic and immunoenhancement effect of Niao Gan Ning(NGN). Methods: The tests of inhibiting the leukocyte infiltration, in-vitro bacteriostasis, water loading with metabolism cage, isometric tension recording and the phagocytosis of abdominal macrophages(AM) were conducted. Results: NGN could obviously inhibit the wandering of leukocyte in abdominal cavity and decreased the number of WBC in mice, and exert bacteriostatic effect to various degrees. NGN also increase the urine volume in water load rats, inhibited contraction of bladder and ureter smooth muscle induced by Carbacol and histamine in rabbits and rats, and increased phagocytosis of the chicken red cells by AM. Conclusion: NGN has a strong anti-inflammatory, bacteriostatic, diuretic and antispasmodic effect.

RESUMO

AIM To observe the effect of polysaccharide from spirulina platensis(PSP) on lung injured by exposing ozone. METHODS The injury model of lung were induced by exposing ozone. The xanthine oxidase method and TBA were used to determine SOD and MDA in serum and lung respectively. The transmission electron microscope was used to observe the structural change of lung cell. RESULTS Compared with model mice, SOD in the groups of PSP administrated mice were increased and MDA were decreased significantly(P
