Orthopaedic wire has been used widely as a good internal fixator in cases of fracture, the ligament reconstruction, and for the stabilization of cervical spine. But if it is used inappropriately, a wire can be easy to fail by elongation, untwisting, or breakage. Among them, the most common failure of wire is breakage. To clarify the mechanism and the causes of wire failure, the authors analysed serial roentgenograms and scanning electronmicroscopic findings of broken wire in total 13 cases, which were experienced at the department of orthopaedic surgery, St. Mary's Hospital, Catholic University Medical College From January 1981 to December 1987. The results obtained were as follows :1. The mechanism of wire failure were classified into the 4 types ; minor continual flexing motion in 6 cases, repeated minor back and forth torsion in 1 case, tension failure in 2 cases and combined type in 4 cass. 2. The causes of wire failure were in appropriate use and inadequte application, a lack of s ufficient mechanical strength, micromotion due to inadequate postoperative imm obilization, early mobilization before tissue healing as well as certain injuries to the wire during handling in operation.

Plasma sprayed coating of the hydroxyapatite(HA) are biocompatible and may contribute to the early fixation of total joint prosthesis. We studied 64 hips(58 patients) who had hydroxyapatite coated primary total hip arthroplasty during the period from January 1992 to June 1993 about clinical and radiological result prospectively. The components have been followed for a minimum of 26 months and an average 31 months. Harris hip score averaged 92 at most recent follow up intervals. At the last follow up, the pain in 7 cases(11%) respectively and only slightly to mild in mostly. Although thigh pain has been occurred in 7 cases(11%), all patients had not trouble in daily activity. In radiological evaluation, there was a rapid and good endosteal bone formation of implants with bone apposition on the Gruen zone 2 and 6 of HA coating area. No radiolucent line formation was detected around HA coated area. In acetabular component, the endosteal bone formation was found in 12 cases and the radiolucent line was occurred in 4 cases. No revision were done for the femoral and acetabular component. The result of the study indicate that this hydroxyapatite coated component can provide satisfactory clinical and radiological result. Further prospective follow up is necessary to determine whether the favorable early result of this implant are maintained over longer period.

The debate about whether depressive disorders should be divided into categories or arrayed along a continuum has gone for decade, without resolution. In our review, there is more evidence consistent with the spectrum concept than there is with the idea that depressive disorders constitute discrete clusters marked by relatively discontinuous boundaries. First, "depression spectrum", "is there a common genetic factors in bipolar and unipolar affective disorder", "threshold model of depression" and "bipolar spectrum disorder" are reviewed. And, a new subtype of depression is so called SeCA depression that is a stressor-precipitated, cortisol-induced, serotonin-related, anxiety/aggression-driven depression. SeCA depression is discussed. But, there is with the idea that depressive disorders constitute discrete subtypes marked by relatively discontinuous boundaries. This subtypes of depressive disorder were reviewed from a variety of theoretical frames of reference. The following issues are discussed ; Dexamethasone suppression test(DST), TRH stimulation test, MHPG, Temperament Character Inventory(TCI), and heart rate variability(HRV).

Congenital agenesis of the right lobe of liver is a rare anomaly and only 33 cases have been reported. CT showed absence of the right lobe of liver and compensatory hypertrophy of the other lobe. We report the CT findings of a new case of this anomaly with a review of the literatures.

A study on branching patterns of middle hepatic artery was performed in 109 patients with A-P and oblique view hepatic angiogram, which refered to size and location of quadrate lobe in CT and SMA portography We could analyze the branching patterns of middle hepatic artery (MHA) in 100 among the 109 patients. MHA arising as a first branch of left hepatic artery was the most common pattern (50%), and MHA arising from proper hepatic artery separately one from left hepatic artery was the next common pattern (35%). MHA originating from left gastric artery, or from anterior or posterior of the right hepatic artery was seen. MHA WAS not found as an accessory or replaced artery except as replaced common hepatic artery.

To investigate the changing patterns of microfilament and microtubule arrangement and influence of myocardial cells and colchicines to microfilament and microtubule formation in cardiac endothelial cells the authors carried out indirect immunofluorescence stain for actin and tubulin with supernatant monoclonal antibodies. Secondary antibodies were IgG FITC conjugate. The results were summarized as follows. Fiberform reactions were stronger in the cells with many processes and spread cytoplasm and they became weaker after the endothelial cells formed monolayer. In the endothelial cells cocultured with myocardial cells the fiberform of the microtubule became less visible compared to control group but fiberform of the microtubule maintained strong intensity as endothelial cells formed monolayer. In the group treated with colchicines, there were no visible differences in microfilaments compared to control group but fiberform of microtubule revealed weaker intensity after colchicines treatment. The intensity of microtubule fiberform returned to control level after 2 days.

The changes in the surface of articular cartilage of femoral condyle from rabbits were evaluated after degenerative changes were made by the technique advocated by Hulth. The medial collateral and both cruciate ligaments were excised, and a medial menisectomy was done. Then the right knee joint was injected with 1 ml of Na-hyaluronate gel every two weeks. The animals were sacrificed at two, four, six, eight, or sixteen weeks postoperatively. After sacrifice, the medial femoral condyle was excised and prepared for the light microscopic and scanning electron microscopic study. At eight to sixteen weeks, there were chondrocyte clones with clefts to the radial zone and increased loss of the height of articular cartilage on the control side; but, on theexperimental side there was a significant delay and lessening of the arthriticresponse. The biocompatibility and the protective effect of joint degeneration of this device make this material a valuable adjuvant in the treatment ofosteoarthritis and the traumatized joints.

This study was conducted to evaluate the effect of ambroxol on preventing the infantile respiratory distress syndrome (IRDS) in preterm birth at the Dept. of Obstetrics and Gynecology of Taegu Catholic Medical Center during the period from Jan. 1996 to Dec. 1996. Total of 68 cases were evaluated including 16 ambroxol group and 52 control group. The result were as follows : 1. In the comparison of preventing IRDS, there was 0 case of IRDS in ambroxol group and 7 cases of IRDS in control group (13.46 %). There was a significant difference between two groups (p<0.05). 2. The side effects of ambroxol after administration were nausea in 5 cases, headache in 3 cases, and chest discomfort in 4 cases, but these were not serious and self controlled. 3. There was no significant difference in neonatal morbidity between two groups (p > 0.05).
