Objectives：The present study has been undertaken to investigate the effects of Mantidis $O\ddot{O}theca$ and Mori Fructus on treatment of osteoporosis in ovariectomized rats. Methods： In this experiment, the rats were ovariectomized. Rats were administered by Mantidis $O\ddot{O}theca$ and Mori Fructus. The levels of bone mineral density, osteocalcin.ALP.calcium.phosphorus in serum, calcium. phosphorus.deoxypyridinoline in urine and calcium.phosphorus.ash weight in bone were measured. Results： 1. The levels of femoral and fibula-tibial bone mineral density were significantly increased in comparison with OVX group at 4, 8 weeks in Mantidis $O\ddot{O}theca$ group. And the levels of femoral and fibula-tibial bone mineral density were significantly increased in comparison with OVX group at 8 weeks in Mori Fructus group. 2. The levels of serum osteoclacin and ALP showed significant decrease in comparison with OVX group at 4, 8 weeks in Mantidis $O\ddot{O}theca$ and Mori Fructus group. The levels of serum calcium showed significant decrease in comparison with OVX group at 4 weeks in Mantidis $O\ddot{O}theca$ and Mori Fructus group. The levels of serum phosphorus showed significant decrease in comparison with OVX group at 4, 8 weeks in Mantidis $O\ddot{O}theca$ and Mori Fructus group. 3. The levels of urine calcium, phosphorus and deoxypyridinoline showed significant decrease in comparison with OVX group in Mantidis $O\ddot{O}theca$ and Mori Fructus group. 4. The levels of fibula-tibial calcium and phosphorus showed significant increase in comparison with OVX group in Mantidis $O\ddot{O}theca$ group and Mori Fructus group. The levels of femoral calcium and phosphorus showed significant increase in comparison with OVX group in Mori Fructus group. The levels of femoral and fibula-tibial ash weight showed significant increase in comparison with OVX group in Mantidis $O\ddot{O}theca$ group and Mori Fructus group. Conclusions： Reviewing these experimetal results, it appeared that Mantidis $O\ddot{O}theca$ and Mori Fructus had efficacy on treatment of osteoporosis.

The in vitro anticoagulant and fibrinolytic activities of crude extracts from insects were evaluated in order to find effective therapeutic drugs for the treatment of myocardial and cerebral thrombosis. We prepared three types of extracts (water, methanol and ethylacetate) from 28 insects for use as raw materials for the activity assays. The fibrinolytic activity was tested using the fibrin plate method and the activated partial thromboplastin time and thrombin time were measured for blood clotting activity. With regards to the fibrinolytic system, water extracts of six kinds of insects displayed a remarkable level of activity with a plasmin-like action. The water extracts of [Catharsius molossus, Eupolyphaga sinensis, Huechys sanguinea, Mantidis $o\ddot{o}theca$, Mimela splendens, and Polistes mandarinus (Vespae Nidus)] exhibited the activity. On the other hand, the methanol extracts did not display any fibrinolytic activity. In terms of the coagulation system, an aqueous extract of silkworm Tongchunghacho (Paecilomyces japonica), Oxya japonica japonica and Buthus martensi (Scorpion) increased the clotting time significantly longer (181 times) than the control. These results suggest that crude drugs from insects are useful sources for the development of new drugs for use in treatments involving blood coagulation and fibrinolysis.
