2.The Effect of Histoacryl(R) for Gastric Variceal Bleeding Which Failed by Ethanolamine Oleate Injection Sclerotherapy.
Korean Journal of Gastrointestinal Endoscopy 1995;15(1):27-32
Treatment modalities of gastric variceal bleeding are endoscopic injection sclerotherapy, endoscopic variceal ligation, combined above two method, operation, TIPS, and percutaneous transhepatic embolization. Recently, Histoacryl was introduced as a new sclerosant of acute variceal bleeding failed by others. So, we studied 18 cases of acute gastric variceal bleeding uncontrolled by EIS using Ethanolamine oleate. Intravariceal injection of Histoacryl is considered as a safe and effective method for hemostasis of intractable acute gastric variceal bleeding uncontrolled by other sclerosants. But, it is important that endoscopist should be in harmony with assistant at injection of Histoacryl. And its shooting speed should be fast because of clogging within the catheter. It is necessary to do long term study for evaluation of eradication effect in acute gastric variceal bleeding.

Soft tissue related complications are quite frequent in limb lengthening. Muscle fibers may proliferate or regenerate after stretching injury over 10-20% of their original length. However, the cells which are engaged in this phenomenon are not confirmed yet. We chased the S-phase cells (phase for DNA replication) in the posterior leg muscle during limb lengthening by immunohistochemical technique. We lengthened the tibiae of fifteen New Zealand white rabbits. We divided them into three groups and each group is consisted of five rabbits. In group 1, we lengthened the left tibiae by 10% of their original length, in Group 2, 20%, and in group, 3, 25%, respectively, At the end of lengthening posterior muscles of lengthened left side and of controlled right side were fixed and processed for Immunohistochemical staining which could detect the incorporation of bromodeoxyuridine(BDU). Labelling index(LI:% of positively stained S-phase nuclei) of group 1 was zero. LI of groups for more than 20% lengthening (sum of group 2 and 3) was statistically significant. In conclusion, nuclei around or within the muscle tissue are in S-phase during limb lengthening which means proliferation of the muscle fivers or of the certain cells that abut muscle fibers.

Many types of meniscal anomalies were reported. Authors found a double-layered lateral meniscus, with one meniscus overlying another. The 39-year old male patient had torn medial and lateral menisci. We performed partial medial and lateral meniscectomy, and incidentally found that lateral meniscus was double-layered. It was characteristic that the upper small accessory meniscus was firmly connected from the posterior horn to middle segments of the lower main meniscus along its peripheral edge. We left it alone. The symptoms were gone, So, it was thought that this anomaly was not related to the patient's symptoms.

Distal radioulnar is a part which has a rotational movement through the function of distal radioulnar joint and extensor carpi ulnaris. The injury mechanism in this area is usually a trauma largely due to traffic accidents. In general these injuries to the distal radioulnar joint are treated by a closed reduction. However, the isolated distal ulnar fracture without radial fracture, which is often called the night stick fracture, is difficult to treat by a closed reduction and a cast immobilization alone, especially if there is a displacement or fracture segment impinging soft tissue or severe comminution. Nonunion has been the frequent outcome with this method of treatment and limitation of rotation of forearm and distal radioulnar joint have occurred due to long period of immobilization or malunion. Thus, a different treatment modality such as open reduction and internal fixation and early active joint motion has arisen as a better treatment modality. In this study, 8 cases of isolated distal ulnar fracture without radial fracture have recieved the operation and the early active joint movement, if a displacement was present either at the time of injury or after the initial closed reduction. As a result, this method has enabled the patients to reduce the rate of complication of nonunion and to recover limitation of joint motion in a shorter time period.

The purpose of this study is to compare the physical health, anxiety and depression of the Dan-Jeon Breathing trained group with those of a non-trained group and to analyze the relationship between the training period of Dan-Jeon Bre athing method and physical health, anxiety, and depression. The number of people in the Dan-Jeon Breathing trained group over 3 months was 149 and in the non-trained group 142. Data were collected from August to October 1999. As tools, 35 physical symptom questions were chosen from The Cornell Medical Index modified by Nam(1965) and from the Symptom Checklist-90-Revision(SCL-90-R) by Kim(1984); 10 questions on anxiety and 13 questions on depression were used in the study. The statistics of the study were gathered by using SPSS Window; the analysis was made by applying x(2)-test, t-test, Pearson correlation, ANOVA and Scheffe tests. The results were as follows. 1. The Dan-Jeon Breathing trained group had lower physical symptom score and showed less anxiety and depression than the non-trained group, which supported the 1st, 2nd, 3rd hypotheses. 2. The longer the training period of Dan-Jeon Breathing, the lower the physical symptom score, which supports the 4th hypothesis, but the 5th and, 6th hypotheses were not supported because anxiety and depression did not get lower as the training period of Dan-Jeon Breathing got longer. 3. The physical symptom score, anxiety and depression that were made by the general characteristics of Dan-Jeon Breathing trained group were analyzed. As a result, the physical symptom score of women was greater than that of men. Physical symptoms score and the rate of anxiety and depression were different by education levels. The degree of anxiety was different by age. Those who have a religion have a higher physical symtoms score than people who have no religion. There was no difference in physical health score, anxiety and depression according to marital status, economic status and occupations. The results suggest that the physical and mental health status of Dan-Jeon Breathing trained group is better than that of the non-trained group. Physical symptoms scores gets lower as the training period of Dan-Jeon Breathing gets longer which results in the improvement of physical health status.

The purpose of this study is to investigate the effect of plasma sprayed hydroxyapatite(HA) coating on bone ingrowth into fiber-mesh coated titanium implant. The shear strength of the HA coatings on interface attachment, the degree of osseointegration of HA coated implants and bone ingrowth of fiber-mesh coated titanium implants were evaluated. The implants were placed transcortically in the femora of mature dogs and evaluated after six weeks. The pushout test showed 33.58±10.87 MPa in HA-coated fiber meshed implants and 20.53±4.91 MPa in fiber-mesh coated implants. In histologic observations, similar quantitative results in the amount of bone ingrowth and osseointegration on both systems. The HA coatings showed direct osseointegration and bone ingrowth on its surface and fiber-mesh without fibrous layer, but the fiber-mesh only coatings showed thin fibrous layer between the ingrown bone and titanium surface. In conclusion, HA-coating on fiber-mesh coated implant provided earlier and stronger osseointegration and bone ingrowth than fiber-mesh only coated implant.

Average anteversion of the femur is 15.3 degree. Ultrasound, computerized tomogram, and three dimensional reconstruction from CT or MRI have been used for more accurate measurement of the anteversion. There are two methods in measuing anteversion angle from CT scan:one is by drawing a mid line through long axis of the femoral neck (conventional method). Another is by drawing a line from the center of the head to that of the neck at the base of the trochanter using several cut slices (Murphy’s method). We compared these methods with fluoroscopic measurement of the Anteversion. We traced the change of the anteversion before and after closed femoral intramedullary (IMO) nailing to evaluate the origin of malrotation of the femur. 1. Normal anteversion angles were measured in 15 cases. Average anteversion angle was 6.9 degrees by conventional method, 12.3 degrees by Murphy’s method, and 12.2 degrees by fluoroscope. 2. Anteversion angles were measured after IM nailing in 18 cases. Average was 17 degrees by Murphy’s method and 15.2 degrees by fluoroscope. Mean of difference between these two methods sea 6.3 degrees. That was 1.7 degrees in normal side. 3. Change of the anteversion angle between before and after IM nailing was measured in 17 cases by fluoroscope. Average anteversion angle before the operation was 11.9 degrees and it was change to 15.8 degrees after operation. Mean of these change was 7.1 degrees. 4. Pereperative traction provides important information on change of anteversion. Reduction excessive flexion of proximal fragment was a origin of change of anteversion during nailing procedure. Conclusion : Malrotation of the femur after IM nailing must be keep in mind and it may be preventable by fluoroscopic control of the rotation in nailing procedure.
