Fibrionolytic activity(FA) of kimchi in rat and FAs of water and methanol extracts of kimchi ingredient were determined using fibrin plate method to see where the active principles for FA are present in kimchi. Nine Sprague-Dawley per each group were fed diet containing 3, 5 or 10% of freeze dried kimchi for 6 weeks. The FA of plasma obtained from 10% kimchi group showed stronger FA than that of control. FAs of 3 and 5% kimchi group were not noticeable. FA from methanol extract of kimchi was approximately 6 times higher than that from water extract assuming that the active material may be present in a fat soluble fraction. From water extract of kimchi ingredients, dropwort, green onion, radish and baechu showed FA in descending order. And from methanol extracts, red pepper powder, radish, green onion and baechu showed FA in decending order. The Fa of methanol extract of red pepper powder was the most noticeable among samples.

The freeze-dried powder of Lumbricus rubellus earthworm was administered orally to rats and its fibrinolytic and antithrombotic effects were investigated. The fibrinolytic activity of plasma was determined by measuring the plasmin activity of the euglobulin fraction and was increased to two-folds of the control at a dose of 0.5 g/kg/day and five times with 1 g/kg/day after 4-day administration. The antithrombotic effect was studied in an arterio-venous shunt model of rats. The thrombus weight decreased significantly from 43.2 mg to 32.4 mg at a dose of 0.5 g/kg/day after 8-day treatment. The level of fibrinogen/fibrin degradation product (FDP) in serum was elevated in a dose-dependent manner during the treatment period. On the 8th day after administration, the FDP value was increased to 7.7 $\mu\textrm{g}$g/ml compared with the control value of 3.3 $\mu\textrm{g}$g/ml. These results support that earthworm powder is valuable for the prevention and/or treatment of thrombotic conditions.

A saline suspension of Lumbricus rubellus earthworm powder (EWP) was administered to rats (1 g/kg/day) orally for 15 days to evaluate an oral effectiveness for thrombotic disorders. Blood was drawn at 2-day interval after the administration. Several parameters for antithrombotic, anticoagulant and fibrinolytic activities were measured, including platelet aggregation, clotting time, plasmin activity and the levels of FDP (fibrin/fibrinogen degradation products), D-dimer, and t-PA antigen. It did not affect platelet aggregation induced by ADP and collagen but anticoagulant activity (aPTT and TT) was gradually increased to two-folds for the first 5 days of administration and back to normal. Fibrinolytic activity of euglobulin fraction was highest on the 11 th day after the administration. The level of FDP was elevated to be comparable to the positve control$ (5-10 {\mu}g/ml)$ after 9-day treatment. Oral administration of the EWP could also reduce the formation of venous thrombus induced with viper venom. Complete blood count (CBC) profiles were within normal ranges except for a slight increase in white blood cells after the oral administration for 15 days. These results suggested that the EWP may be valuable for the prevention and/or treatment of thrombotic diseases.
