Object: Fucoidan is a sulfated polysaccharide in brown marine algae. Gagome kombu (Kjellmaniella crassifolia) is a Japanese edible seaweed and contains fucoidan abundantly. Recently, it was reported that fucoidan from Gagome kombu (GKF) had anti-tumor, immune-enhancing and anti-coagulant activities. In this study, we conducted a safety of GFK on the healthy adult.
Methods: Thirty-two healthy volunteers were randomly divided into 4 groups and administered a standard volume and three times volume of two kinds of test drinks containing GKF for 4 weeks.
Result: No abnormal changes were observed after test drinks ingestion on blood chemistry, urinalysis, hematological data and blood pressure. No severe adverse events related to test drinks were observed. Moreover, increase of Th1 cells was observed in immunological analysis.
Conclusion: This study suggests that GKF is safe in healthy adults.

It is essential to prolong the term as possible in the treatment of threatened premature delivery. We report a case of threatened abortion successfully treated with hochuekkito. The patient was 31 year-old pregnant woman with lower abdominal pain. She was diagnosed to be at the risk of premature delivery on 21 weeks and 5 days of gestation. Intravenous ritodrine hydrochloride was started and she had to stay in bed. Severe side effects of ritodrine hydrochloride such as palpitation, tachycardia, tremor, nausea, and loss of appetite were appeared and she was consulted to our department on 23 weeks and 1 day of gestation. Those symptoms were markedly improved after administration of hochuekkito extract. She delivered a male infant of 1230g birth weight on 28 weeks of gestation. Hochuekkito suppressed severe side effects, and enabled to continue the infusion of ritodrine hydrochloride, suggesting the usefulness of Kampo therapy in the treatment of threatened premature delivery.

Folic acid contained in potato (Solanum tuberosum L.) tubers is concentrated in potato chips by dehydration during frying. It is a vitamin recommended to young women which helps protect fetus from congenital disease. Additionally, folic acid can lower plasma homocysteine concentrations, a known independent risk factor for cardiovascular disease. This study was designed to determine whether the dietary consumption of potato chips affect serum folic acid concentration and plasma homocysteine concentration in human subjects. Results showed a significant increase in serum concentrations of folate 1, 3, and 6 hours after ingestion. Vitamin B₆, on the other hand, increased significantly after 3 hours of intake. In contrast, plasma homocysteine concentration decreased significantly 6 hours after ingestion. These results suggest that potato chips would be a good dietary source of folic acid for humans.
