Recently spondylolysis and spondylolisthesis have become major causes of low back pain in the orthopaedic field and numerous methods have been designed for its treatment. The authors used the LSDS with posterolateral fusion for 12 cases of spondylolisthesis and spondylolysis having low back pain and tenderness, which were operated on during the 4 years from Jan. 1983 to Jan. 1986 at Wallace Memorial Baptist Hospital. The advantages of LSDS with posterolateral fusion are as follows. l. In the case of distraction spondylodesis of interspinous process between L4 and Sl; A. the diameter of intervertebral formaina as well as of the whole spinal canal is widened. B. decompression is accomplished. C. the mechanical stress on the posterior columns of vertebral arch is lessened because the plumb line is anteriorly transferred. 2. Technique of LSDS; the knee-elbow position has the advantages of maximal kyphosis together with expansion of the space between the vertebral arches, as well as a reduction in the tendency to bleed because the blood collects in the abdominal vessels. 3. Internal fixation of grafted bone is not necessary. 4. A large surface area for unit mass of graft is in contact with blood supply. 5. Hypertrophy or displacement of graft can not encroach upon the epidural space; as may occur in certain circumstances following posterior fusion. The results of treatment are follows; l. In the case of improvement of symptoms after facet infiltration and knee-elbow position, satisfa- ctory results after LSDS were obtained. 2. The progression of slipping was not occurred after LSDS. 3. In increased lumbar lordosis, we have noted the instability especially with the changes from the mean values in Fergusons angles. 4. In the slip angle, there is some tendency to the lumbosacral instability correlating with the in- crease in the body weight. 5. We have also noted that the functional result was not closely related with degree of displacement.

OBJECTIVE AND METHODS: To determine correlations among ambulatory renin activity, ambulatory blood pressure and microalbumin excretion rate, 66 Korean essential hypertensives were studied after 4 week wash-out period. The ambulatory blood pressure was monitored every 30 minutes and mean BP were calculated automatically. Urinary microalbumin excretion rate(UAER) and ambulatory plasma renin activity(aPRA) collected at mid-day were measured by radioimmunoassays. Subjectives were divided into 2 groups by aPRA value(2ng/ml/hr). RESULT: 14 cases were high renin group and 52 cases low renin group. The mean BP were 148.83/94.69mmHg in low renin group, and 146.57/98.07mmHg in high-renin group without difference. UAER were not different also between both groups. 23.07%(4/14) of non-dippers were included in high renin group and 25.58%(12/52) in low renin group without statistical difference. The aPRA was significantly related to UAER and systolic and diastolic mean blood pressure. Also UAER was related significantly to day mean blood pressures. CONCLUSION: Thus aPRA is thought to be a meaningful indicator to predict hypertensive renal target organ damage as well as blood pressure measured with 24-hr ABPM.

The obliteration of a fat plane between the gastric carcinoma and the pancreas is a major criterion on CT scan for pancreatic invasion of gastric carcinoma. However, this sign is not always a reliable indicator of invasion, as the patients with gastric carcinoma are often emaciated. Producing a false positive CT findings. The purpose of our study is to improve the diagnostic accuracy of pancreatic invasion of gastric carcinoma in cases which the fat plane between the gastric carcinoma and the pancreas is obliterated in conventional CT scan. The authors performed lateral decubitus as well as supine CT scans and upper gastrointestinal series(UGIS) in 49 pathologically proven cases in which the fat plane was obliterated between the gastric carcinoma and the pancreas on conventional supine CT scan. Pancreatic invasion was suggested when the fat plane was obliterated persistently in the lateral decubitus view as well as the supine CT images and the involved gastric wall and adjacent pancreas maintained constant approximation despite postural change(CT+), and when the gastric tumor moved downward on the erect view of the UGIS no more than 1.5 time the height of the first lumbar vertevral body(UGIS+). Among 49 cases in which the fat plane between the gastric carcinoma and the pancreas was obliterated on supine CT scan, pancreatic invasion was confirmed pathologically in 11 cases(22.4%). Eight of 11 cases proven as pancreatic invasion were correctly diagnosed as pancreatic invasion by this combined analysis (CT+/UGIS+, 72.7%). Twenty seven of 38 cases proven as no pancreatic invasion were correctly diagnosed as no pancreatic invasion(CT-/UGIS-, 71.1%). Twelve cases showed CT +/UGIS-or CT-/UGIS+, so it was inconclusive whether there was invasion or not. The overall diagnostic accuracy was 71.4%. In conclusion, combined analysis with supine and lateral decubitus CT and UGIS is useful for improving diagnostic accuracy for pancreatic invasion by gastric carcinoma in patients of which the fat plane between the gastric carcinoma and the pancreas is obliterated on conventional supine CT.

PURPOSE: To assess the value of MR imaging compared to CT for the staging of gastric carcinoma when body-wrap-around surface coil, intravenous glucagon, motion suppression technique and effervescent granules are used. MATERIAL AND METHOD: CT and MRI were performed for thirty-five patients with gastric carcinoma. Postcontrast CT scan was performed immediately after oral effervescent granules and Buscopan were given. Before MR imaging, BWA surface coil was wrapped around the upper abdomen. T1 coronal, sagittal and axial SE images (TRITE=400/15 msec) were obtained immediately after oral effervescent granules and glucagon were given. Respiratory compensation and presaturation techniques were used for each imaging. Three radiologists evaluated independently for randomly mixed 70 sets of CT and MR images. The signal intensity of gastric mass and enlarged lymph nodes were compared to the signal intensity of the adjacent pancreas, liver and spleen to evaluate any discriminating features between them. RESULTS: The accuracy in the diagnosis of pancreatic invasion was 83.8% on MRI and 74.3% on CT (p < 0.05). The accuracy of MRI and CT was 77.1% and 72.4% in detecting of gastric tumor respectively (p > 0.05), 73.3% and 68.6% in gastric serosal invasion (p> 0.05), 50.5% and 42.9% in lymph node metastasis (p > 0.05). The gastric mass and enlarged lymph nodes were hypointense to the intensity of pancreas and liver in more than 78% of cases. CONCLUSION: MRI was comparable to CT scan for the staging of gastric carcinoma. Therefore, MRI could be used as an alternative or adjunctive diagnostic modality in the staging of gastric carcinoma.
