Abstract: To study the health functions of crude extracts from squid spermary tissues.Experiments for evaluating the health functions including anti-fatigue effect,anti-oxidization effect and immuno-regulation activity of crude extracts from squid spermary tissues were performed in this study.It showed that the in mice investigated extracs could lengthen the time of swimming and rodding,decrease the consumption of live glucogen during sporiting and lower the level of blood lactic acid after sport.It also revealed that the crude extraction could lower the level of blood malondialdehyde (MDA) and heighten the SOD activity in blood,while at the same time raise the NK cell activity,macrophage rate,phagocytosis index and leves of cell immunology.The investigated extracts had effects of anti-fatigue,anti-osidization and immuno-regulation and thus demonstrated the potential for being developed into a natural marine health food.
