Antibiotic-acrylic bone cement composites demonstrated antibacterial activity as a result of diffusion of antibiotic from bone cement into surrounding enviroment, accordingly, the use of antibiotic incorporation to bone cement for the prevention and treatment of infection after joint surgery replacement has been adovocated. Early report of clinical success by using antibiotic-acrylic bone cement composites are encouraging. Our authors applied this concept to the treatment of chronic osteomyelitis. Antibiotic contained with bone cement was chosen by sensitivity test on pus culture finding. Seven cases of chronic osteomyelitia treated by using antibiotic-acrylic bone eement composites were .studied in the Department of Orthopaedic Surgery, Kyung Hee University Hospital from July 1979 to March 1981. The follow-up period was from 3 months tc 22 months. The results were as follow: 1. Six cases showed no evidence of recurrence except one by using antibiotic acrylic bone cement composites. 2. The impregantion of antibiotic in acrylic bone cement shall be regarded to be effective in increasing the local antibacterial activity by leaching the antibiotic into surrounding tissue over a period continiously in treatment of chronic osteomyelitis. 3. The use of antibiotic-acrylic bone cement compositea into dead space by saucerization are consid- ered an one such approach to the decrease of dead space. 4. The impregnation of antibiotic in acrylic bone cement is regarded a new concept in treatment of chronic osteomyelitis.

Tureta and his colleagues have stressed the important role that vessels play in osteogenesis. Numerous arthors attempted to provide new bone formation by placing vascular pedicles into the bone. Some reports are convining, but experimental model and histological investigation leave something yet to learn. We conducted an experiment to demonstrate the feasibility of using a vascular bundle to create new bone formation in medullary canal. Vasculsr bundle of the femoral artery and vein was transplanted in same side of the femoral canal of rabbits. The transplanted vascular bundle was studied histologically for eight weeks. At 3 weeks transplanted artery started proliferation of intima and media, and its lumen was obliterated completely at 6 weeks. Transplanted vein collapsed from begining, and didn't involve in revascularization and new bone formation. At 2 weeks the proliferation of capillaries promoting revascularization originated from the adventitia of the transplanted artery, and peaked at 6 weeks. New osteoid appeared around the transplanted vessel at 2 weeks, and surrounded the entire vessel in 5 weeks, and had no more progression in amount at 6 weeks. Cortical hypertrophies showed in the vascular bundle transplanted group from 3 weeks. Examination of control group revealed no sign of new osteoid formation around the hole during the whole study period.

The authors analysed statistically 186 cases of the glaucoma patients among 20,785 out-patients who visited to our eye clinic from Jan. 1957 to Dec. 1969. The incidence of the glaucoma was 0.895% which was remarkably lower than the other reports. The following results were obtained. 1) Among the 186 cases, there were 85 male and 101 female patients. 2) There was no significant difference in left and right eye. 3) 51-60 year age group was prevalent (49 cases). 4) The age group over 40 occupied 61.3%. 5) The open angle glaucoma was the highest incidence.

It is currently necessary to manage chronic ischemic foot gangrene because the rate of hospitalization and operations is increasing as a result of diet change and the growth of an aging population. Chronic ischemic foot gangrene is caused by Buerger`s disease, atherosclerosis and particularly, diabetes. In this study, we used the Wagner ischemic index with Doppler flowmeter and Wagner classification on 62 patients over 8 years from 1991 to 1998 as an index for treatment and prognosis. We measured the systolic pressure to determine the ischemic index, and according to Wagner the blood flow was inadequate in cases of diabetic foot gangrene and nondiabetic foot gangrene when it was below 0.45 and 0.35, respectively. According to the observation of clinical symptoms, we divided the cases by Wagner classification. Based on the above data, we performed conservative treatment, skin graft, local flap, superficial sural arterial island flap and amputation. We then followed up the patients and observed the treatment results. We concluded that the Wagner ischemic index with Doppler flowmeter and Wagner classification was useful in determining, selecting, and predicting the rate of survival or death as a result of amputation and graft when a surgical operation is performed.
