Porphyra polysaccharide could exert diverse biological activities such as immunomodulation, antioxidation and antiaging.The purpose of this study was to investigate the neuroprotective effect of porphyra polysaccharide on 6-OHDA induced cytotoxicity in MES23.5 dopaminergic cells.The results showed that porphyra polysaccharide (1, 10-1, 10-2 mg/mL) alone did not have any toxic effects on MES23.5 cells.Pretreatment with porphyra polysaccharide (1, 10-1, 10-2 mg/mL) could significantly antagonized 25 μmol/L 6-OHDA-induced toxicity to MES23.5 cells, resulting in an increase in cell viability compared with that of 25 μmol/L 6-OHDA solely treated group.However, none of the above doses could antagonize 75 μmol/L 6-OHDA-induced toxicity.The results suggest that porphyra polysaccharide only have partial neuroprotective effect against 6-OHDA-induced toxicity on MES23.5 dopaminergic cells.

洗澡能除去汗垢油脂，消除疲劳，舒经活血，改善睡眠，有利于身体健康。但随着冬天的来临，我们应该适当地降低洗澡的频率，缩短洗澡的时间，不然，洗澡非但无益于健康，还会洗出一身病来。 次数不宜太多。洗澡次数太多，会把皮肤表面正常分泌的油脂及正常寄生在皮肤表面的保护性菌群全部洗掉，容易引起皮肤瘙痒，皮肤的抵抗力也会减弱，容易患皮肤病。 时间不宜过长。经测定，在淋浴中有50％的三氯甲烷和80％的三氯乙烷变
