1. Effect on Cardiovascular System: oleic acid, myristic acid, palmitic acid and dihydrogen iodate histamine show periaqueductal gray stimulation on isolate heart[1]. Laminine show decreased the blood pressure effect[2-6].

2.Reducing Blood Lipid: Water extract show reducing blood lipid action on Hyperlipoproteinemia rabbit and rat model[7,8]. Diethyl ether and alcohol extract, Alginate sodium and lamarin, laminarin sulfate show similarity effect also[3,8-11].

3. Anticoagulated blood: :Lamarin and laminarin sulfate show thrombosis activity in vivo and vitro through inhibit thrombin and Plasmin inhibitor activity[7, 10, 12-17].

4.Effect on Immune Function: laminarin and its’ sulfate can enhance macrophage phagocytize and lymphocyte transformation[13]. Angustate Laminaria water extract can enhance macrophage phagocytize erythrocytolysin and white cell level[18]. Alginate sodium and fucose in polysaccharide can enhance immune function[9,19].

5. Anticancer: Kelp show anticancer effect on mice breast cancer[20], fleshy tumor S₁₈₀[21] and leukemia L₁₂₁₀[3]in vivo and lung cancer cell in vitro[11]. Alginate sodium and lamarin show anticancer activity on mice fleshy tumor S₁₈₀[9-10]. Viva-natural extract can inhibit AKRT leukemia cell line[22].

6.Hypoglycemic: laminarin show hypoglycemic activity on normal and alloxan induced hyperglycemia mice[23].

7.Effect on Intestines Smooth Muscle: Laminine show papaverine like effect on mice isolated small intestine[4].

8. Radioprotective: alginate sodium and laminarin show a radioprotective on γradiation exposure mice[17,12,24].

9.Other Action: Laminarin can enhance hematopoietic activity[24]. alginate sodium can used as dextran for plasma substitutes[11]. Its extract show anti-mutagenesis[25], antioxidant[26,27] and induced labor[28].

1. Infusion phlebitis：dry Haidai(Kelp ) for treatment of infusion phlebitis. Results: treatment group for 3days that 25 cases were cured, 12 cases were markedly improved, effective in 7patients, 1 case ineffective.

2. Chronic tracheitis: Haidai(Kelp ) root water pill for  treatmentof chronic bronchitis in 92 cases, 1 agent per day, 10 days as  1  course of treatment,  for two courses. Results: a course oftreatment, 26 cases were nearly controled (28.2%), 17 cases were powerfully(19.6%), 31 patients wer improved (33.7%), 18 cases were invalid (19.5%), theeffective rate was 80.5%, significant efficiency was 47.8%; for two courses, 33patients were nearly controled (37.5%), 21 cases were powerfully (23.9%), 18cases were improved (20.4%), 16 cases were invalid (18.2%).
