The extraction, the activity and the content of hormons (testosteron, estrogen and progesteron) from some Echinodermata at Viet Nam were reported. The subjet: Echinodermata collected at Thanh Hoa and Nha Trang. The result: The solven system of methylen chloroid and of methanol have higher effect than of ethanol and ether ethylic. The extracts from egg of sea star, sea urchin tested on white rat and rabbit were proved to have activity of testosteron, estrogen and progesteron. Egg of sea star, sea urchin, pyloric ceaca of sea star and meat of Bohadschia argus Jaeger have adequately steroid hormones (testosteron, estrogen and progesteron). In pyloric ceaca of see star, the content of testosteron, estrogen and progesteron are higher than in their egg

Our experimental results showed that: 1. EBS1 have low acute toxicity in experimental models. 2. When EBS1 were administered to animals per os, the different parameters have no signification for: weight, liver, spleen, kidney, blood and biochemistry in comparision with control ones.

Background: Hepatocellular carcinoma (HCC) is the most common primary hepatic tumor and one of the most common cancers worldwide. HCC is a primary malignancy of hepatocellular origin. Objectives:The aim of study is to combinate therapy of transarterial chemoembolization and percutaneousethanol injection afterward emerging metatasis caused by fine needle aspiration cytology. Subjects and method: A 50 years old male patient with hepatocellular carcinoma having a diameter of tumor more than 5 cm was treated by combination of transarterial chemoembolization and percutaneous ethanol injection from December 2000. Results & Conclusion: Results of study showed that: Transarterial chemoembolization and percutaneous ethanol injection are the two of non-surgical methods for treatment of hepatocellular carcinoma which are most commonly available in applied clinical activities at present. Up to now, the patient's life expectancy after therapy is more than 6 years that means the result of treatment is very good. However, the emerging metatasis into the anterior-right-Iower chest wall that was caused by fine needle aspiration cytology should be reviewed for further evaluating clinical experience, especially in cases with quite clear imaging features of untrasonography and significantly elevated AFP level higher than 200 ng/rnl.
