Injuries to the ligament and other supporting structures of the knee joint are becoming very frequent because of the increasing popularity of sports and the complexity of traffic & industrial accidents in the modern society. There have been much development in undtrstanding the anatomy, function and biomechanics of the knee in recent years. Accurate surgical technique, energetic physiotherapy and appropriate use of brace are essential to obtain the maximum rehabilitation of the injured knees. It is long realized that some sort of knee brace is necessary as a means of stabilizing the injured knee either as a conservative treatment or as a adjuvant treatment treatment pre-or postoperatively before full rehabilitation is attained. We have introuced Lenox Hill Derotation Brace for the first time in Korea, employed in 24 case(26 knees) and found the following advantages. 1. It is light and easy to apply. 2. It is possible to control all kind of the knee instability. 3. It is possible to engage in any activity with the Brace in place without limitation of the knee motion. therefore, we recommend the Brace as a very usefull adjuvant for the proper treatment of the injured knee.

Segmental dilatation of small intestine or colon can induce signs of intestinal obstruction, such as abdominal distension, vomiting and constipation. There are no anatomical gross obstructive lesions, and moreover, ganglion cells are observed in both dilated and undilated distal segments of the intestine. It often accompanied by other congenital anomalies. We reported two cases of segmental dilatation of the intestine in the newborn infants, one in small intestine and the other in colon, with brief review of the related literatures.

It is interesting and in important to study histochemical changes of glucose-6-phosphatase (G-6-Pase) activity by electron microscopy in order to promote the knowledge needed for diagnosis and prognosis in such liver diseases as von Gierke's disease, hepatoma and various other hepatocellular alterations of different origins. Since we had not accomplished the electron microscopic demonstration of G-6-Pase, although light microscopic studies on changes of the enzyme activity were done in this laboratory, this investigation was planned to obtain a satisfactory technique for ultrastructural demonstration of the enzyme activity. Unfixed frozen sections (80 micro thick) of mouse liver were washed for 2~3 minutes in a 0.4M sucrose solution (pH6.8) containing 4 mM lead nitrate and then incubated for 15~20 minutes at 32~37 degrees C in several different media to which 0.4M sucrose solution was added: A) a modification of the original Chiquoine medium, B) the first modification of the Wachstein-Meisel medium C (the second modification; the 2% lead nitrate solution was reduced in amount to 1.5 m1 instead of 3.0 ml in the medium-B). After incubation, these sections were fixed in 1% osmic acid containing sucrose, followed by embedding in Epon, ultrathin-section, mounting and staining with uranyl acetate and/or lead nitrate. By incubating the sections in the medium (B or C), satisfactory preparations were obtainable for its electron microscopic demonstration. The granular deposits of reaction products were found characteristically on the membranous component of the rough-and smooth-surfaced endoplasmic reticulum and unclear envelope. Occasional deposits were observed within cisternae or vesicles, in the nucleus, and immediate1y adjacent to the cisternal membrane and glycogen areas.

Prednisolone, a cortisol analogue, was given intraperitoneally to rats with 5, 10 or 15 doses of 5 mg. per kg. of body weight per day. Sacrificing the animals 24 hours after the last injection, unfixed frozen sections from small pieces of liver tissue were incubated and stained by a modification from the method of Wachstein and Meisel(1965) for glucose-6-phosphatase (G-6-Pase) activity. Some of the tissue blocks were processed for staining with hematoxylin and eosin for histopathological observation. Glucose-6-phosphatase activity, being represented histochemically by brownish-black deposits, was progressively increased after administrations 5 or 10 times. With 15 doses of prednisolone the general histochemical picture of G-6-Pase activity appeared to be similar to that of the control group, except for a different distribution of hepatocytes possessing strong activity. In prednisolone treated rats, the swollen hepatocytes showed a marked, cytoplasmic vacuolization and nuclear pyknosis, particularly in the periportal and midzonal areas of hepatic lobules. Some discussion of the G-6-Pase corticosteroids are presented in terms of their metabolic effects.

Injuries to the ligament and other supporting structures of the knee joint are becoming very frequent because of the increasing popularity of sports and the complexity of traffic and industrial accidents in the modern society. Vast knowledge of the anatomy, function and biomechanics of the knee joint together with the mechanism of its injuries have been recently documented. To obtain complete recovery of the injury as a goal, early diagnosis, prompt definite treatment, sufficient time of immobilization and well planned strenuous exercise are important. The clinical analysis of 28 patients with 31 knees by the concept of knee instability and preliminary result of treatment were reported. Through combined operative and conservative treatment, excellent and good were obtained in 96.8 percent.

Radiographic measurement of cervical spine is very important in cervical spine injury especially those without fracture. Authors measured the retropharyngeal space, retrotracheal space, lordortic curve and sagittal diameter of cervical spinal canal in 148 cases of normal adult male. The results are as follows: 1 . In normal Korean adult male maximum retropharyngeal space is 7mm in C, level and Smm in Cs level. Maximum retrotracheal space is 16mm in C, level. 3. Loss of normal lordotic curve is shown in 21 cases(14.2%), 4. Average sagittal diameter of C, level is 21.27mm-it's the largest of all the cervical spinal cana1s, and that of C, level is 16.15mm-it's the smallest.

Intertrochanteric fracture of femur is increasing in their incidence. Recently Ender nail and compression hip screw are very popular but they have disadvantage in the treatment of intertrochanteric fracture of femur. We have treated 49 cases of intertrochanteric fractures from December 1979 to October 1985 using Ender nail(31 cases) and compression hip screw(18 cases) respectively and compared the results. The summary of the results obtained were as follows: l. Average operation time was 72 minutes in Ender nail group and 146 minutes in compression hip screw group. 2. Average blood loss was 154ml in Ender nail group and 661ml in compression hip screw group. 3. Roentgenographic union was obtained in 12 weeks in both groups. 4. Minor postoperative complications were 24 cases in Ender nail group and 3 in compression hip screw group. Among 24 complications of Ender nail group, 19 were about the knee joint. Our conclusion is that Ender nailing is useful modality in the treatment of unstableintertrochanteric fractures who are old and high risk patients.

Disseminated Fusarium infection has rarely been encountered in neutropenic cancer patients. The clinical features include fever, positive blood cultures, severe myalgias, disseminated ecthyma gangrenosum-like skin lesions, ocular symptoms and multi-organ-system involvement. The mortality rate reported so far exceeded 70% despite antifungal treatments. We report here the first two cases of disseminated fusarial infections in Korea. The first patient contracted pneumonia during severe neutropenic period following consolidation chemotherapy for acute myelogenous leukemia(AML). Fusarium oxyshrum was cultured from bronchoalveolar lavage fluid. The patient remains free of fungemia after successful antifungal treatment of high-dose amphotericin B and terbinafine. The second patient had relapsed AML and suffered from disseminated fusarial infection involving lungs with characteristic skin lesions. The patient succumbed to refractory leukemia and the fungal infection. A brief review of the literature ensues with the case report.

To investigate the earlier cellular alterations(Glucose-6-Pase activity and morphologic features) caused by a hepatotoxin, thioacetamide (TAA), a single dose of the agent (200mg per kg of body weight) was given intraperitoneally to mice, which were sacrificed at intervals of 4, 8 or 16 hours after corresponding treatments. For histochemical study of glucose-6-phosphatase (G6Pase) activity, unfixed frozen sections were incubation of the Wachstein and Meisel medium and stained. The smallest pieces of liver tissue were fixed in glutaraldehyde and osmic acid, and stained by the routine electron-microscopic techniques. Some pieces of liver were fixed in 10% formalin, embedded in paraffin, and stained with hematoxylin and eosin. There was a rapid and progressive loss of G6Pase activity, in an orderly time sequence, in the experimental group. There were also morphologic changes: loss of cytoplasmic basophilia, cell infiltration and necrosis in the centrilobular and intermediate zones, and an increase of sER, small vesicles and ribosomes in the cytoplasm of hepatocytes, the marked changes of nuclei and nucleoli, and a slight increase of lipid droplets in the cytoplasm at 16 hours after intoxication. The correlation between these cellular alterations was discussed in view of mechanisms in the hepatotoxic action.
