Since the time when the lumbar discogram was used as the clinical diagnostic method for the first time in 1952, many problems have been pointed out to this method, and moreover, in presentday tendencies for the diagnostic method, the lumbar discogram is carried on even useless by majority. One of the important reasons is that so many studies for the lumbar discograms have reported so many false positive lumbar discograms at the high ratio. Hower we found a certain usefulness of the lumbar discogram incidental to the operation. The purposes of our operative lumbar discogram are those; 1) to observe the radiological configuration of the lumbar discogram. 2) to measure the amount of the the dye injected into normal and abnormal lumbar discs, especially in our Koreans. 3) for confirmation of the diagnosis when the myelographic finding is suspicious. 4) for confirmation of the Ievel especially when the number of the possible lesion is more than one. We investigated and analyzed the 35 lumbar discograms of 26 patients and compiled the statistics.

The purpose of this study was to investigate the possibility of distraction osteogenesis in membranous onlay bone graft on the mandible and to clarify the histology of bone repair during distraction osteogenesis in the membranous onlay bone in a dog model. Four dogs, 5 months of age at the beginning of the experiment, were used for this study. The zygomatic arch was exposed in the subperiosteal plane and the full-thickness zygomatic arch was harvested to 3 centimeters in length. The lateral surface of the mandibular body was exposed in the subperiosteal plane and the membranous onlay bone graft was performed with firm contact using screws. The osteotomy on the membranous onlay bone graft and underlying mandibular body was carried down week 1 in dog 1, week 2 in dog 2, week 3 in dog 3, and week 4 in dog 4 after membranous onlay bone graft. The external distraction device was applied to the mandibular body. Mandibular distraction was started 7 days after the operation at a rate of 1mm per day for a total of 10 mm distraction over 10 days. After completion of distraction, the distraction device was left in place for 6 weeks bony consolidation of the distracted area. Radiographs were carried out at 2 weeks, 4 weeks and 6 weeks after distraction. New bone between the native underlying mandibular segments was generated in the distracted zone in all dogs. The new bone between the native underlying mandibular segments was generated in the distracted zone in all dogs. The new bone between segments of membranous onlay bone graft was not generated in dog 1, but it was generated in dogs 2, 3 and 4. However, in dog 2 and 3, the new bone between segments of the distracted membranous onlay bone graft presented less firmness with fibrous tissue than that of the native underlying mandibular segment. Histologically, the distracted gap between segments of the membranous onlay bone graft was composed of much fibrous tissue in the central zone while activated osteoblastic cells formed new bone in the margins of the distracted gap in dogs 2 and 3. In dog 4, there were abundant osteoblastic activities in the distracted gap and the new bone appeared as nearly-normal cortical bone. In conclusion, these findings suggested that membranous onlay bone graft had an osteogenic capacity and that distraction osteogenesis was possible in membranous onlay bone graft.

Reconstruction of soft tissue defect with exposure of the tendons and bone in the lower third of the leg and the heel represents a challenge to plastic surgeons. The sural artery flap is a fasciocutaneous flap supplied by the sural artery that accompanies the sural nerve and connects with a septocutaneous perforator of the peroneal artery via a suprafascial network of vessels. For the coverage of soft tissue defects, we operated on 10 patients using a distally-based sural artery flap. The sites of the soft tissue defect were the lower third of the leg in 7 cases and the heel in 3 cases. The size of flap varied from 3.5x4cm to 12x18cm. Nine of 10 flaps survived completely. One flap in which the sural nerve was preserved showed partial necrosis but healed spontaneously. Two flaps showed slightly venous congestion which disappeared after a few days. The advantages of the sural flap are a reliable blood supply, easy and quick elevation of the flap, preservation of the major artery and minimal donor site morbidity. The disadvantage of the flap is hypoesthesia at the lateral part of the foot. In conclusion, the distally-based sural artery flap can be used safely for soft tissues coverage in the lower third of the leg and the heel.

It has been suspected that the cannula of the ultrasonic generator became heated during liposuction, and that the heated cannula might possibly damage the soft tissues such as vessels, nerves and muscles. To confirm these suspicions, the actual temperature of the cannula was measured after being switched on, and the influence of the heated cannula on the soft tissues of 30 rabbits was studied macroscopically and microscopically. When the cooling system of ultrasonic generator was not operated, the temperature of a cannula tip increased to 100degrees C in 10 seconds, and the temperature of a cannula shaft did not increase over 40 degrees C. When the cooling system of the ultrasonic generator was operated, the temperature of the cannula tip increased to 70 degrees C in 20 seconds and to 100 degrees C in 1 minute. The stronger ultrasonic power was, the higher the temperature of the cannula tip was. When the heated cannnula tip touched the muscles, vesseles and nerves directly, the arterial and venous walls were perforated in about 20 seconds and 10 seconds, respectively. Gross changes of the muscles, such as color change and depression of the contacted area, were seen in about 30 seconds, and histological changes occurred in about 3 seconds. When adding the Klein solution, an infiltration solution for increasing the destructive effects of the ultrasound, the onset time of tissue damage was significantly shortened in vessels and nerves, but there was no significant difference in muscles. Although there was no finding of damage by the ultrasonic wave itself on the vessels, nerves, and muscles during ultrasonic liposuction, this study confirmed that the heated cannula could damage vessels, nerves, and muscles. Thus we must try to avoid placing the cannula at certain areas for more than 10 seconds douring the ultrasonic liposuction.

Bone graft is an important procedure in craniomaxillofacial reconstruction and the success of reconstruction depends on the survival of the grafted bone. In this study, the survival of the membranous inlay bone graft on the mandibles of dogs was investigated with bone scan and histologic examination. The inlay bone graft, 1x2cm critical-sized bone, was completely separated from the lower border of the mandible of dogs and then refixed to the original site. Bone scan and histologic examination were done at 1,2,3 and 4 weeks postoperatively. The bone scan after 1 week showed radioisotope uptake on the margin of the grafted bone and the isotope count was 21% compared to the uptake of the normal bone. After 2 weeks, the radioisotope uptake in the grafted bone increased to 52% of normal bone uptake. After 3 and 4 weeks, the degree of isotope uptake was 111% and 124% respectively. Histological findings after 1 week showed the absence of osteoblastic activity and 6 viable blood vessels in one 200X magnified field, which was 25% compared to the vessels of the normal bone. After 2 weeks, osteoblastic activities were noted and the number of viable blood vessels totalled 15, which was 63% of the vessels of the normal bone. After 3 weeks, osteoblastic activities increased and the number of viable blood vessels totalled 21, which was 88% of the vessels of the normal bone. After 4 weeks, there were markedly increased osteoblastic activities with a total number of 23 vessels, which was 96% of the normal bone. In summary, the revascularization of the membranous inlay bone graft began from the first week after bone graft, and then it gradually increased. After 3 weeks, the revascularization had returned to a nearly normal value compared with the value of the near-by normal mandibular bone.

This study was intended to analyze the relation between the psychic traumatic experience and the psychological health of the aged. The authors carried out this study by means of the combined anxiety-depression scale (CADS) and the preadolescence traumatic experience scale (PTES) with 278 aged men and women residing in Taegu from September to October 1988. The results were as follows: 1. Based on the scores evaluated by CADS, the scores of the both groups showed that comparative group was accounted for 40.15±6.19, while the experimental group for 57.75±6.37, which showed significantly higher score in the experimental group (p<0.001). 2. The experimental group showed significantly higher early experience score than the comparative group in the dietary difficulty, alcoholism among family members, disunion between husband and wife, trouble between mother and children, early mother loss, parent's indifference and unwanted birth (p<0.001). 3. The experimental group showed higher early experience score than the comparative group by sex, age, marital status and grown location (p<0.001). 4. When the subjects were included in the unemployed and in the middle or low classes and their parents were engaged in agriculture and commercial business and believing in buddhism or no-religion, showed higher experience score (p<0.001).

Embolization of a carotid cavernous fistula(CCF) by means of a detachable balloon is a well-established method for treating CCFs while preserving a patent parent internal carotid artery(ICA). However, failure to embolize the CCF may occur on a few occasions. Herein we describe a stent-assisted Guglielmi detachable coil embolization that completely occludes the fistulous opening rather than fills the cavernous sinus. By applying this technique, we successfully treated a CCF, without compromise of the parent ICA in patients who has failed with balloon technique previously.
