Tabanus anticoagulant protein (TAP) was isolated from the whole body of the tabanus, Tabanus bivittatus, using three purification steps (ammonium sulfate fractionation, gel filtration on Bio-Gel P-60, and ion exchange chromatography on DEAE Sephadex gel). The purified TAP, with a molecular weight of 65 kDa, was assessed to be homogeneous by SDS-polyacrylamide gel electrophoresis, and an isoelectric point of 7.9 was determined by isoelectric focusing. The internal amino acid sequence of the purified protein was composed of Ser-Leu-Asn-Asn-Gln-Phe-Ala-Ser-Phe-lle-Asp-Lys-Val-Arg. The protein was activated by $Cu^{2+}\;and\;Zn^{2+}$, and the optimal conditions were found to be at pH $3\sim6\;and\;40\sim70^{\circ}C$. Standard coagulation screen assays were used to determine thrombin time and activated partial thromboplastin time. Chromogenic substrate assays were performed for thrombin and factor Xa activity. TAP considerably prolonged human plasma clotting time, especially activated partial thromboplastin time in a dose-dependent manner; it showed potent and specific antithrombin activity in the chromogenic substrate assay. Specific anti-factor Xa activity in TAP was not detected. Overall, this result suggested that TAP has significant anticoagulant activity on blood coagulation system.

This study was investigated the anti-angiogenic activities of Cnidium officinale Makino and Tabanus bovinus by using Chorioallantoic membrane (CAM) and rat cornea. First experiment, the fertilized chicken eggs were kept in a humidified egg incubator at $37^{\circ}C$. After 4 days incubation, about 3 ml of albumin was aspirated from eggs with an hypodermic needles through a small hole drilled at the narrow end of the eggs, and the shell membrane on the floor of the air sac was peeled away. Embryos with chorioallantois of 3~5 mm in diameter were employed for the assay of antiangiogenic activity. Retinoic acid was used as a positive control for this experiment. After 48 h of treatment. branching pattern of blood vessels below coverslip containing retinoic acid ($10{\mu}g/egg$) was dramatically decreased. A simiar angiogenic inhibition was observed in the CAM treated with $50{\mu}g/egg$ of Cnidium omcinale Makino and Tabanus bovinus extracts. Second experiment, rat corneal neovascularization was induced by suturing (one stitch) the cornea with 10-0 nylon, and terramycin was applied on the cornea for I week to prevent corneal inflammation. In the cornea of rats untreated with herbal extracts, numerous vessels were usually seen invading the cornea by day 2 or 3 after suture, and reaching the lesion area within 5~6 days. Corneal neovascularization was gradually increased and peaked at 3 weeks. In contrast to this, herbal extracts conspicuously inhibited the angiogenesis, Oral administration of herbal extracts (20 mg/kg body weight/day) for 4 weeks significantly inhibited the rat corneal angiogenesis induced by suture, and the length of blood vessels in herbal medicine-treated rat cornea was conspicuously lower than that in control animals. A similar phenomenon was also observed in the rat cornea treated with thalidomide (200 mg/kg body weight/day). These findings indicate the anti-angiogenic properties of Cnidium officinale Makino and Tabanus bovinus, suggesting that these properties may be one of the pharmacological mechanisms underlying the anti-tumor and anti-metastatic activities of herbal extracts tested in this study.

Purpose : The pharmacological effects of medicinal remedies traditionally used in Asian countries for improving the blood circulation were examined on isolated rat thoracic aorta strips in organ baths. Methods and results : Each experimental medicine was consecutively extracted under reflux with water. Of three medicinal remedies . Hirudo(HI) having the strongest acute relaxant activity in endothelium-intact arteries, Tabanus(TA), Empoly ohaga(EO) were showing dose-dependent relaxant activity. Long-term relaxant effects were showed in Hirudo(HI) and Empoly ohaga(EO). In endothelium-injury test using carbachol, Hirudo(HI), Tabanus(TA) and Empoly of ohaga(EO) were not damaged to endothelium. Conclusion: As a result of this study, the possibility that a part of medicinal remedy may contribute to the beneficial effects in blood circulation was proposed, but inter-individual variation has been observed. Also, further studies on the vasorelaxant effects of these remedies are still required.

The cytotoxicity of crude insect drugs was measured using HeLa cells originating from human cervix and uterine cancer. using the dye uptake assay in order to find potential anticancer agents. Three kinds of extracts (buffer, methanol and ethylacetate) were prepared from 26 insects and used as raw materials for the activity assay. Among these, the buffer extracts from Tabanus, Mylabris and Huechys showed a potent anticancer activity, and those from Catharsius, Red ant, Scorpion, Tabanus and Vespae Nidus showed a strong L-amino acid oxidase (AAO) activity as well as cytotoxicity. In contrast, buffer extracts from Gryllotalpa orientalis and Apriona germari larvae showed greater/more rapid Hela cell growth than that of other insects.

Habitat preferences of benthic macroinvertebrates were studied according to the different substrate composition. Although it was hard to determine the common dwellers in the habitats with cobbles and pebbles, some taxa such as Ephemera orientalis, Davidius lunatus, Tipula KUb, Isonychica japonica and Tabanus amaenus etc. occurred preferably in the habitats with gravel/sand. In all the sampling stations, the numbers of species collected in the habitats with gravel/sand were always remarkably smaller as compared with the habitats with cobbles and pebbles.

Object When angiogenesis is excessive, Cancer, RA, Blindness, Psoriasis, Hemangioma, Diabetic retinopathy, Granulation, etc are induced. On the contrary, when it is insufficient, Stroke, Heart disease, Ulcer, Infertility, Scleroderma, artherosclerosis, delay of the wound recovery, etc occur. In recently, the methods which is control of abnormal angiogenesis are researching actively in relathion to anticancer research. This study is search for effective drugs which suppress this angiogenesis, in the ingredients of the herbs that invigorate and dispel blood stasis using to treat intravascular coagulation in the oriental herbal medicine. Methods We maked 80 % methanole extracts of Cnidii Rhizoma, Olibanum, Myrrha, Corydalidis Tuber, Curcumae Radix, Curcumae longe Rhizoma, Zedoariae Rhizoma, Salviae miltiorrhizae Radix, Polygoni cuspidati Rhizoama, Leonuri Herba, Persicae Semen, Carthami Flos, Trogopterorum Faeces, Achyranthis Bidentatae Radix, Manitis Squama, Eupolyphaga, Hirudo, Tabanus, Lycopi Herba, Artemisiae anomalae herba, Vaccariae Semen, Sappan Lignum, Gleditsiae Spina, Draconis Resina, Leonunari Semen, Selaginelliae Folium, Spatholobi Caulis, and these extracts were tested for MTT viabilaty test, BrdU incorporation, Tube foramtion assay on ECV304(immotalized human umbilical vein endothelial cell) at the concentration of $50{\mu}g/ml$, $100{\mu}g/ml$, $200{\mu}g/ml$, $400{\mu}g/ml$ Results All extracts except Draconis Resina have no cytotoxicity at the $100{\mu}g/ml$, and in BrdU incorporation test, proliferation rate were reduced below 60% at the concentaraion of $100{\mu}g/ml$ by Zedoariae Rhizoma, Sappan, Lignum Gleditsiae, Spina Draconis Resina Vaccariae Semen. Zedoariae Rhizoma Sappan Lignum Gleditsiae Spina Draconis Resina Vaccariae Semen Olibanum, Achyranthis Bidentatae Radix showed inhibition effects on tube formation of ECV304 at the concentration of $100{\mu}g/ml$. Conclusion At the concentration of $100{\mu}g/ml$ in which cytotoxicity is not found, Zedoariae Rhizoma, Sappan Lignum, Gleditsiae Spina, Vaccariae Semen showed the inhibition effect on proliferation and tubeformation of ECV304.
