Cementless type of total hip prosthesis has especially been used in the cases of revision of severe osteoarthritis and rheumatoid arthritis and also as a primary procedure instead of cement type recently. However, problems regarding loosening of the type remain on controversy. The present study was performed to solve the problems such as inserting angle of the socket, resection angle of femoral neck, type of the stem of femoral component and materials having good biocompatibility. Method: Biomechanical calculating system (Rigid Body Spring Model by Kawai), mechanical forces using Instron type testing machine, and histopathological and contact microradiographic studies were used on the experimental animals. Results: Ideal inserting angle of the socket into the acetabulum was thirty five degrees, resection at the base of the femoral neck with eight millimeters' height of calcar from the intertrochanteric line. Press fitting type of the femoral component into the intramedullary canal was favorable. Al

3 or hydroxyapatite ceramics showed good biocompatibility to bone. Based on these experimental achievement, clinical application using total hip system has been successful.

To evaluate the effectiveness of fibrin glue (FG) as a hemostatic agent in vascular surgery, an experiment by using canine model as well as and clinical studies were undertaken. In group A, the amount of bleeding from anastomotic site was compared between the group of fibrin glue sealing and the group of no treatment using PTFE graft for iliac arterial reconstruction. In group B, Golaski vascular graft was pretreated with fibrin glue in experimental group and also the amount of hemorrhage from vascular graft in certain length was compared to that of non treated group. The amount of bleeding was significantly lower in fibrin glue pretreatment group than that of control one. In clinical application, the same design of study was undertaken with the patient who had aorto-iliac reconstructive surgery for aneurysmal or occlusive disease by using knitted dacron bifurcation graft. It was also found that bleeding was well controled in fibrin glue treated vascular graft. The microscopic examination of graft-arterial specimens at the anastomotic site harvested 1 month after implantation revealed the presence of no significant inflammatory reaction. We concluded that fibrin glue provides good hemostatic action in the practice of vascular surgery.

Pokeweed Mitogen (PWM), a type of lectin, has the potential to induce anticancer cells. In order to utilize this potential and apply it for cancer therapy by hemoperfusion, PWM was immobilized to PMMA-DVB beads and the beads were packed into a minicolumn (PWM-C). Human peripheral lymphocytes were activated by circulatory contact stimulation through the PWM-C for 1 hour. After circulatory contact stimulation through PWM-C, lymphocytes were collected and used for effector cells. Cytotoxicity tests were measured by
51Cr release assay using K-562 cell and Daudi cell for target cells. This material could argue the NK activity and the cytotoxicity against NK-resistant target cell. PWM-C activated lymphocytes were injected to the MKN-1 tumor bearing nude mice intralegionally, and suppression of tumor growth was recognized. Anticancer activities by the treatment of direct hemoperfusion (DHP) with PWM-C were examined in Vx2 tumor bearing rabbits. A single DHP treatment using PWM-C was performed 6 days after tumor inoculation. The suppression of the tumor growth could be found for 25 days. It is expected that PWM-C can be used for anticancer material as an immunomodulator.
