The first myelography with air was carried out by Walter Dandy in 1919, and the myelography with positive contrast medium was done by Sicard and Forestier in 1922. Since Pantopaque was adopted as a contrast material by University of Rochester group in 1944, it has been rapidly popularized. Although higher diagnostic accuracy has been made with a development of the diagnostic aids such as electromyography, discography, epidural venography and computerized tomography, myelography has been popularized in our country with electromyography. The authars have seen and studied 107 cases of herniated lumbar disc with respect to the diagnostic accuracy of myelographic examination from January, 1976 to December, 1981 at the department of Orthopedic Surgery, Yonsei University College of Medicine. The results were as follows: l. Of the 107 cases, 59 were found in the age of 20 to 40 years and the ratio of male and female was 2:l. 2. Fifty eight cases (54.2%) had no history of back injury, but 40 cases (37.4%) had sprain of the back and 9 cases had direct trauma history. 3. In all cases, plain X-ray and myelogram were taken. Among them 55 cases showed narrowing of intervertebral space in plain film, and 100 cases showed positive myelographic findings such as lateral indentation of dural sac (41 cases), hour-glass defect (30 cases), root sleeve defect (12 cases), block defect (10 cases) and combined defects (7 cases). 4. Sixty one cases which confirmed by operation, the most frequent level of disc herniation was in L4-5 space. Clinical diagnosis was correct in 57.4%, and myelographic accuracy was coincided with operative finding in 80.3%. 5. Twelve (19.7%) of the 61 cases showed discrepancy between myelographic and operative findings, and these 12 cases consisted of 5 cases of level discrepancy, 3 cases of false positive and 4 cases of false negative.

The authors clinically analysed the causes of metallic failure in 21 cases after treatment of comminuted fracture of femur at Department of Orthopaedic Surgery, Kang-Nam St. Marys Hospital during 5 year period from May 1981 to December 1986. In this series, the nature of metallic property was not studied which may influence the result of failure. 1. Metallic failure occurred in seventeen self-compression plates, one Kuntscher nail, one I-beam nail, one Ender nail, and one Angle blade-plate. 2. Seventeen patients had fractures in the middle or distal one third of femur. 3. Metallic failure occurred from 3 to 19 months following open reduction and internal fixation. The time interval between internal fixation and failure was 9.6 months on an average. 4. Metallic failure of the self-compression plate was observe in the empty hole over the fracture site in 14 out of 17 patients. In the Kiintscher, failure developed at the interlocking hole corresponding with the fracture level. In the Ender nail and Angle blade-plate, failure developed at the fracture site, and in the I-beam nail plating, failure developed at the neck of the fixation screw, and not at the plate. 5. The cause of metallic failure in 17 self-compression plate-treated cases was improper plating such as varus plating in 4, absence of medial buttress due to cortical comminution in 10. Above mentioned two conditions were combined in 4 cases, in which one case of Angle blade-plate was included. Incorrect position of I-beam nail, inadequate postoperative management following Ender nailing and incorrect selection of implant in one case of Kiintscher nailing were the other possible causes of metallic failure.

PURPOSE: Bile acids (especially deoxycholate) was known to be toxic and mutagenic on colon epithelium. They proposed at least four mechanisms for the bile acid toxicity. It is the one of these mechanisms that bile acid inhibits the xenobiotic metabolizing enzyme activity (esp glutathione S-transferase, GST). So we measured the cytosolic GST level of colon carcinoma cell lines after deoxycholate exposure whether or not the deoxycholate lowered the cytosolic GST activity. METHODS: Three colon cancer cell lines (LoVo, SW480, HT29) were used for this study. We calculated the cellular toxicity by MTS method. And cytosolic GST activity was measured according to the method as Habig described. For total GST activity, 2.5 mM 1-chloro-2,4-dinitrobenzene was used for substrate, and measured as absorbance in 340 nm. RESULTS: Basal cytosolic GST level for LoVo, SW480, HT29 cell line was 514.59+/-27.01, 291.63+/-38.44 and 344.58+/-47.92 nmol/min/mg cytosol protein. GST level did not changed significantly after 5 days culture without DCA. But GST level was decreased significantly to 128.63+/-21.35, 134.33+/-41.76 and 163.10+/-22.73 nmol/min/mg cytosol protein each cell line after 5 days deoxycholate exposure (p<0.005). CONCLUSION: Cytosolic GST level was lowered significantly after deoxycholate exposure for 5 days. One of the mechanisms of bile acid toxicity for colon cancer cell is proposed to inhibit cytosolic GST activity.

Iron deficient state occurs commonly in the athlets, and the cause may be inadequate iron intake, loss of iron from sweat, blood loss of gastrointestinal tract, and hematuria. The age of the athletes ranged from 11 to 17 years old. I messured red blood cell count, hemoglobin, hematocrit, and related hematologic factors in the 32 adolescent female athletes and 21 female controls. a hematologic comparison was perfomed between the athletes and controls. The results obtained were as follows: 1) A value of hemoglobin were 11.6+/-1.4g/dl in the athletes and 12:4+/-0.8g/dl in controls (p<0.05). 2) Hematocrits were 34.1+/-3.4% in the athletes and 37.4+/-2.3% in controls (p<0.05). 3)A value of red bolld cell distribution width values were 13.9+/-2.1% in the athletes and 12.2+/-1.1% in controls (p<0.05). 4) Serum iron was 87.7+/-30.3ug/dl in the athletes and 121.8+/-39.0ug/dl in controls (p<0.001). 5) Total iron binding capacity was 445:6+/-31.8ug/dl in the athletes and 384:6+/-54.2ug/dl in controls (p<0.001). 6) Mean transferrin saturation values were 19.7+/-6.9% in the athletes and 32.5+/-10.8% in control (p<0.001). 7) Ferritin was 14.5+/-10.0ng/ml in the athletes and 33.9+/-13.9ng/ml in controls (p<0.001). 8) The duration of exercise was 4.8+/-2.5 years in the stage III iron deficiency, whil 3.0+/-2.0 years in normal group in iron deficient state (p<0.05).

We report a case of gastro-colic fistula caused by ectopic gastric mucosa developed at transverse colon. Fistula was detected by colonofiberscopy. And fistulous tract was proved by barium enema. Meckel's diverticulum scan finding was similar to that of GI bleeding; e.g. injected radioactivity was secreted into the lumen and moved along the lumen. There was no bleeding. And there was no diverticulum in the colon. Absence of diverticular pouch may explain this unusuaal GI bleeding-like scan finding rather than focal collection of radioactivity, which is typical of ectopic gastric mucosa found in the Meckel's diverticulum. Ectopic gastric mucosa was confirmed by colonfiberscopic biopsy. We suggest GI bleeding-like pictures should be included differential diagnosis of Tc-99m-O4 (ectopic gastric mucosa or Meckel's diverticulum) scan.

Histiocytosis X(Langerhans cell histiocytosis) is a rare prolifertive disorder of Langerhans cells that includes Lettere-Siwe disease, Hand-Shiiller-Christian his ase and eosinophilic granuloma. Since many authors have reported in anintermediate and poarl classified form histiocytosis X has a namenclatural had nosologic problem. We report a case benign cutaneous variant of histiocytisis X. A four-month-old boy had shown multiple skin-colour papules on the trunk, head and nik for one month. Extensive in- vestigations failed to detcct any systemic involvement. The clixron microscopic findings of the skin biopsy specimen were Qefinitely diagnostic for histiocytosi. X Since he did not sbow evidence of internal organ involvernent and any further progression of he skin lesion, no therapy was given. Over the next two months the disease underwent spontane us and complete remission.
