The purpose of present study was to observe the radiographic finding and histologic response by Confocal Laser Scanning Microscopy(CLSM) on interface of the bone and titanium implant coated by chitosan. The tissue of rabbit tibiae to the surgical placement titanium implant coated by chitosan was examined at 3, 9 and 24 days postoperatively. The radiographic finding showed that surrounding bone density of implants was not significantly different compare with the bone on 3 and 9 days group. A large amount new bone was formed on 24 days group, the reason was osteconduction activity by chitosan. The CLSM analysis show that the surface coating by chitosan filled the gap between bone and implant on 3 days group and filled by mew born on 9 days group. On 24 days group, the bone and titanium surface was filled by lamella bone. This results indicated that this enhanced the initial stability of implant significantly and chitosan induced osseointegration around implant. CLSM allows the non-destrutive histo-tomography of bone biopsy as well as clinical practice. We conclude that CLSM allowed a good comprehension of the nature of bone-implant contact, avoiding artifacts due to the thickness of the specimen.

Direct intraarterial measurement of blood pressure is an important diagnostic procedure in critical patients and premature baby care. Direct measurement was more accepted and confident method in physician than the indirect methods. But the presence of a significant amplification of systolic pressure in peripheral artery may lead to important error. So we have investigated the degree of the systolic pressure amplification from the ascending aorta to the femoral artery in children. Pressure waves recorded in the ascending aorta, aortic arch, diaphragmatic level of the descending aorta, common iliac artery, and femoral artery in 37 patients with congenital heart disease, aged 9 months to 21 years old (mean 7.16 yrs old) during diagnostic cardiac catheterization. The results were as follows 1) Amplification of the systolic pressure increased progressively from the ascending aorta to the femoral artery (16.7%) 2) Diastolic pressure decreased progressively from the ascending aorta to the femoral artery (6.5%) 3) Mean pressure decreased progressively from the ascending aorta to the femoral artery (1.5%) 4) Pulse pressure increased progressively from the ascending aorta to the femoral artery (42.8%) 5) There was significant drop (7%) of the systolic pressure of the ascending aorta compared with that of left ventricle. The results showed that the peripheral amplifications were limited to the systolic and pulse pressure, but the diastolic and mean pressure in peripheral arteries were lower than that of central artery.

We performed an epidemiologic survey to investigate the dermatologic problems from cutting oils in metal workers. The personal questionnaires and dermatologic examinations were performed on 360 metal workers who were working at 50 metal industries. The pH meter (HANNA 8520) and the atomic absorption spectrometer(G.B.C. 902) were employed to measure the pH values of cutting oil and the concentration of heavy metals contained in cutting oil respeetively. The results were as follows : 1. The prevalence rates of the dermatologic disorders from cutting oil were 46.0% of eontact dermatitis, 10.9% of black comedone, and 7.1% of paronychia in orders. The dermatologic disorders that seemed to be not directly associsted with cutting oil were callosity(19.1%), burn by metal chips(9.8%), and mechanical injury(5.7%). 2. The localizations of the contact dermatitis and the black cemedone from cutting oil were 84% of hands, 6.6% of face, and 5% af forearms. More detailed localizations of the contact dermatitis and black comedone that developed in hand were 29.6% if finger tip, 27.6% of palm and palm finger, and 19.1% of palm finger only in orders. 3. The prevalence rates of the dermatologic disorders by the of cutting oil were 51.5% of soluble oil, 68.8% of insoluble oil, and 80.8% of mixed cutting oil which containing both soluble and insoluble oil. 4. The mean pH value of aoluble cutting oil was 8.0 and that of insoluble cutting oil was 7.0. 5. The concentrations of heavy metals contained in soluble oil were 32.2 mg/m3 of chrome, 6.42 mg/m3 of nickel, and 4.85 mg/m3 of cobalt. The concentrations of heavy metals contained in inspluble oil were 24.11 mg/m of chrome, 4.63 mg/m3 of nickel, and 2.30 mg/m3 of cobalt.
