STUDY DESIGN: The indications of the lumbosacral spinal fusion has been very controversial. The posterior lumbar interbody fusion has the popularity of the spinal fusion: coaption of large surface areas of cancellous bone without shear forces, anatomic restoration and maintenance of more normal dimensions of the joint space, total discectomy as preparation for the fusion, and the accomplishment of better neural decompression without creating instability of the spine. OBJECTIVES: To evaluate the long-term results of the surgical management of degenerative lumbar disease by the modified transdiscal posterior lumbar interbody fusion technique using cancellous chip graft were analyzed. SUMMARY OF LITERATURE REVIEW: The disadvantages of classical posterior lumbar interbody fusion has a injury of nerve root by extensive retraction with the insertion of peg grafts into the disc space, compression of root by graft retropulsion, inadeguate removal of annulus fibrosus and end plates from excessive bleeding from venous plexus of spinal canal and from vertebral cancellous bone. MATERIALS & METHOD: Author's 43 cases who had transpedicular instrumentation and modified transdiscal PLIF using cancellous chip graft since 1989 in the Department of Orthopedic Surgery, Korea University Hospital were analyzed, retrospectively. After preparation of the interspace has been complete by total discectomy, removal of the cartilaginous end plates and perforation of the cortical plates using the ring curette, cancellous chip grafts are inserted into the interspace with the Funnel technique. The structural success of each fusion was documented by sequencial radiographs. The criteria for fusion included: homogenous amalgamation of the fusion mass and vertebral bodies, trabeculation, mass configuration, and no motion demonstrable by hyperflexion studies. The results obtained were as follows: 1. Stable fusion was obtained in 39 patients(91%) at post-operative 6 months. 2. Clinically no patient developed neurologic deficit after fusion and 41 patients (95.3%) had good results by Gill's criteria. 3. No significant complications influencing operative result were observed except minor complications such as paralytic ileus, transient dysuria and superficial infection. 4. In conclusion, modified transdiscal PLIF procedure using cancellous chip graft showed excellent clinical and radiological results to achieve spinal fusion and the procedure is technically feasible and should be considered more widely employed.

Authors performed film mammography in 2167 patients with breast complaints who had visited to Yong DongSeverance hospital, Yonsei University from October 1, 1983 to September 30, 1985. Authors analysed 62 cases offilm mammographic findings and 35 cases of ultra mammographic findings among confirmed 62 fibroadenomas and alsoauthors analysed histopathologic cell type and ultra mammographic findings of confirmed fibroadenomas. The resultsfollowed: 1. The most prevalent age group was 3rd and 4th decade(74%). 2. The common dense breast pattern by Wolfeclassification were P2 and DY patterns(80%) in film mammograhy. 3. The most common size of fibroadenomas was1.1-3.0cm (71%) in long diameter. 4. Film mammographic findings of fibroadenoma generally showed single mass in 54lesions(87%), well defined margin of mass in 45 lesions (58%) and halo sign in 62 lesions(80%). Well definedmargin of mass is prominant in ductal cell dominant fibroadenoma(71%) , however lobulation of margin is commonlyseen instromal component dominant fibroadenoma(15%) and spiculated margins of mass can be seen in mixedfibroadenoma(6%) and stromal component dominant fibroadenoma(3%). Halo sing of fibroadenoma was commonly seen inductal cell dominant fibroadenoma(86%) and stomal component dominant fibroadenoma(85%). 5. Ultra mammographicfindings of fibroadenoma showed oval shaped mass in 26 lesions(15%) with smooth margin of mass in 43 lesions(84%)and showed mostly intermediate internal echo in 48 lesions(94%). Relationship between histopathologic cell typeand ultra mammographic findings were. Round shaped mass(67%), lateral shadowing (74%) was common in mixed type offibroadenoma, lobulated margin of mass(45%), intermediate(94%) with unifrorm(78%) internal echo was common instromal dominant type of fibroadenoma and smooth contour (100%), uniform internal echo fo mass(83%) was common inductal cell dominant type of fibroadenoma. Most ultra mammographic L/T Iratio of fibroadenoma was 0.5-1.0 in 37lesions(73%) 6. The diagnostic accuracy of film mammogahy in fibroadenoma was 92%, however combined imagingmodalities raised the diagnostic accuracy into 95%.

PURPOSE: The chemoembolization with Lipiodol and doxorubicin hydrochloride is used in patients with hepatocellular carcinoma. What condition is the ideal emulsion of Lipiodol and doxorubicin for excellent anticancer effect? METHOD AND MATERIALS: Microscopic evaluation was performed on the emulsions, which were varied with different specific gravities of doxorubicin solutions, degrees in mixing of the emulsion, and amount of Lipiodol. RESULT: 1. Maximal amount of doxorubicin solution was contained in Lipiodol droplets and the release of doxorubicin from the droplets were delayed, when specific gravity of doxorubicin was equal to that of Lipiodol (SG, 1.28). 2. The optimal therapertic ratio of Lipiodol and doxorubicin was 3:2 at least, as in the emulsion less than 3:2, unmixed free forms of doxorubicin solution were increased. 3. The emulsion mixed by pumping 50--100 times had smaller Lipiodol droplets and contained larger amount of doxorubicin solution in the droplets than by pumping 20 times. CONCLUSION: We recommend the emulsion with specific gravity of doxorubicin equal to Lipiodol (SG. 1.28), the ratio of Lipiodol and doxorubicin closo to 3:2, and the mixture prepased with puming 50--100 times.

We studied 54 normal volunteers and 30 patients with Bell's palsy by magnetically and electrically evoked direct stimulations of facial nerve. A magnetic coil was placed tangentially to the parieto-occipital area and the stylomastoid foramen. Magnetic stimulation (MS) was less painful and able to excite deeper tying neural structures. Magnetically and electrically evoked direct stimulations of facial nerve showed the same characteristics in excitability and nerve conduction, but they could not be evaluated on the basis of the same normative data. We identified a locus of the impulse generation that might be closer to the exit of facial nerve from the brainstem. Compared with normal controls, MS-evoked CMAPS of patients with Bell's palsy had no responses, longer latencies, lower amplitudes, or disperses pattern. This study shown that MS at the stylomastoid foramen can not be used for the evaluation of the facial nerve conduction study in place of electrical stimulation(ES). As the transcranial MS can stimulate intracranial proximal portion of facial nerve directly and noninvasively, it can give additional information on the evaluation of facial nerve. Transcranial MS combined with ES may provide the means for assessing the entire facial nerve.
