To analyze the changes of range of motion and manifestation frequency of impingement sign according to ages in shoulder impingement syndrome after excluding complete rotator tears by MRI, the authors reviewed 74 patients whose impingement injection tests to the subacromial space were positive in the Dankook university hospital. We used paired student t-test for comparison with the contralateral shoulder. l. Average forward elevation, abduction, external rotation and internal rotation of the shoulders were not significantly different in stage I and II, but significantly different statistically in stage II over 40 years old. 2. Average external rotation at 90degrees abductions of the shoulders was not significantly different statistically in stage I, II and stage II over 40 years old. 3. Frequencies of the painful arc were 83% in stage I, 71% in stage II and 58 % in stage II over 40 years old. Physical examinations of painful arc in 1 case of stage II, 7 cases of stage II over 40 years old were impossible because of limitation of motion. 4. Frequencies of lateral impingement sign were 100% in stage I, 86% in stage II, 100% in stage II over 40 years old. Frequencies of Neer's impingement sign were 75% in stage I, 67% in stage II, 88% in stage II over 40 years old. Frequencies of Hawkins impingement sign were 67% in stage I, 62% in stage II and 82% in stage over 40 years old. Except external rotation at 90degrees abduction, range of motion of the shoulder may be decreased in impingement syndrome over 40 years old. Because of difference of frequencies, more than two impingement signs should be tested for the diagnosis of shoulder impingement syndrome.

The mechanism of cytolysis by complement attack of nucleated cells(NC) is of special interest in comparison to that of red blood cells. It is known that NC death by membrane attack comples, C5b-9, is caused by many factors, i.e., efficiency of complex assembly, activation of intrinsic metabolic pathway by signal transduction, cytotoxic effect of the channel itself and natural repair ability. These factors suggest that colloid osmotic lysis, known in red blood cells, does not fully explain the complement-mediated cell death of NC. In this study, the authors investigated correlation between biochemical and morphological changes to prove "Ca2+-mediated metabolic death"8~13) representing a mechanism of NC death caused by C5b-9 attack. The L1210 cells, mouse leukemic cell line carrying small complement channel(TAC5b-91) were used in the experiments. The amounts of intracellular adenine nucleotides to extracellular Ca2+, ouabain, KC1 and dextran were analyzed by bioluminescence method using luminometer. Cell viability was checked by 0.4% trypan blue dye and LDH release. Morphological observation of TAC5b-91 was done by immunocytochemical staining and electron microscope. The results were as follows: 1) The release of ATP, ADP and AMP followed by cell death was rapid and progressive along the incubation time at 37 degrees C and it was accelerated in 1.5 mM of [Ca2+]0. 2) There was no evidence of ATP repairment in the TAC5b-91. 3) Extracellular KC1(150 mM), dextran(0.66 mM) and ATP supplement(0.2 microM) could not effectively inhibit ATP depletion and cell death. Ouabain(27 and 100 microM) enhanced cell death and could not completely prevent ATP loss. 4) Most of the mitochondria showed swelling, loss of cristae and Ca2+ deposit in matrix in the electron microscopic observation. Rapid, sustained and irreversible depletion of adenine nucleotides was due to Ca2+ deposit with destruction of mitochondria and also the leakage through transmembrane channels. Moreover this energy depletion was accelerated by high extracellular Ca2+ concentration. These results indicate that Ca2+-mediated, energy exhaustion is one of the mechanisms of the metabolic cell death by C5b-9 attack of NC.

The pulmonary arterial pressure(PAP) was reported to be higher in essential hypertensives than in normotensives, but the underlying mechanisms for the higher PAP were not known exactly. In order to observe the changes of pulmonary hemodynamics and to get an insight into the mechanism of the pulmonary hypertension, if any, in essential hypertensive patients, the autors performed the cardiac catheterization in 13 normal controls(group A), 14 coronary patients with normal systolic left ventricular function and systemic blood pressure(group B), and 15 essential hypertensives with normal coronary artery and systolic left ventricular function(group C). 1)Pulmonary arterial pressure(PAP) was 19.2+/-3.2/8.1+/-1.9/12.0+/-1.9(s/d/m)mmHg in group A, 25.0+/-6.2/12.8+/-4.0/16.3+/-4.5mmHg in group B, 29.3+/-6.1/12.8+/-4.0/18.2+/-3.6mmHg in group C. The PAP was higher in group B and C than that of group A(p<0.005). 2) Pulmonary vascular resistance(PVR) was 88.2+/-34.9 dyne.sec.cm(-5) in group A. 137.8+/-74.5 dyne.sec.cm(-5) in group B and 173.9+/-77.5 dyne.sec.cm(-5) in group C. In group B and C, PVR was increased compared to that of group A(p<0.05, p<0.005, respectively). 3) Pulmonary capillary wedge pressure(PCWP) was 6.6+/-2.8 mmHg in groupa A. 9.9+/-2.9mmHg, and 9.6+/-3.6 mmHg in group C. PCWP in group B and C were higher than that of group A(p<0.005). 4) Systemic vascular resistance(SVR) was 1298+/-340 dyne.sec.cm(-5) in group A, 1466+/-362 dyne .sec.cm(-5) i group B and 2255+/-439 dyne.sec.cm(-5) in group C. In group C, SVR was increased compared to that of group A and B(p<0.002). 5) Significant correlation was demonstrated between PVR and PCWP in group A(r=-0.74, p<0.05). 6) In group B, significant correlations were shown between PAP and PCWp(r=0.55, p<0.05), between PAP and PVR(r=0.69, p<0.05). 7) In group C, significant correlations were demonstrated between PAP and PCWP(r=0.55, p<0.05), between PVR and SVR(r=<0.51, p<0.01). Above results revealed that PAP and PVR were increased in essential hypertensives without left ventricular failure and this elevated PAPseemed to be affected in part by increased PCWP, and increased PVR in accordance with increased SVR.

Extensor pollicis longus tendon rupture is well known as a complication of fracture of the distal radius. There is a higher risk that the tendon of extensor pollicis longus will rupture in undisplaced distal radius fracture than in those which are displaced. We have experienced three cases of rupture of the extensor pollicis longus tendon after undisplaced distal radius fracture. Those were treated by tendon graft and tendon transfers. The results were satisfactory without complications. The patients with undisplaced distal radius fracture should be careful concerned about possibility of rupture of extensar pollicis tendon.

Orthognathic Surgery

Fractures of the femoral head associated with hip dislocation are uncommon injury and all traumatic fracture-dislocation of the hip must be treated as surgical emergencies. But, there was no uniformity of treatment of fracture-dislocations of the hip were treated by operative and conservative methods in Chonbuk National University hospital were observed between March 1983 and January 1987; Operative treatment is included screw fixation method and fixation with bone pegs. And so, the followings were summsrized: 1. The most common cause was dash-board injury and patients sex was msle in majority. 2. Frequency of the type of femoral head fracture was the most in Pipkin type I, the next was type IV. 3. The better result was noted in operative treatment than in conservative method as above good. 4. Bone pegging method was relatively not superior to screw fixation. 5. The following complications were encountered, 1 case of sciatic nerve palsy, 1 case of traumatic arthritis.

The present study was undertaken to investigate serum carboxyhemoglobin levels in smokers according to the amount of cigarrettes. many studies have shown definite and consistent relations between smoking and ischemic heart disease. The purpose of this study is to show that COHb levels can be used to discriminate between persons having certain ischemic heart disease and persons without these disease more accurately than is possible by using smoking history alone, and thus to suggest that this may be a good indicators of risk. The results of this study are as follow : 1) The incidence of ischemic heart disease in smoker is higher than that in non-smoker. 2) For a given COHb level there is no clear increasing trend in the population of affected subjects with increasing cigarette consumption and there is no significant change cigarette consumption under duration of 10 year's smoking history. 3) For a moderate and a heavy smoking categories there is a consistent effect of an increasing proportion of affected subjects as the COHb level rises and there is a significant change with COHb level under duration of 10 year's smoking history. 4) The same results are as over duration of 10 year's history. 5) There were no significant interaction between under duration of 10 year's smoking history and over duration of 10 year's smoking history. In conclusion, it seemed that cigarette smoking may play an important factor in development of ischemic heart disease by increasing serum carboxyhemoglobin level.

The purpose of this retrospective study was to evaluate the efficacy of arthroscopic repair of Bankart lesion using the biodegradable polyglyconate implant(Suretac) for the treatment of traumatic anterior shoulder instability. Although the arthroscopic procedure using the Suretac device has some technical advantages over others, there have been reports of the higher failure rate than open procedure. Eight shoulders in 8 patients who had traumatic anterior instability of the shoulder with Bankart lesion were managed with this procedure. They were followed up for average 2 years (range 1 year 4 months to 2 years 5 months). During the follow-up period, all the patients showed full range of motion of the shoulder without recurrence of instability. It was our impression that success rate of the procedure could be improved by careful selection of the patient, the accurate arthroscopic technique, and the good rehabilitation program.
