Three cases of chronic subdural hematoma superimposed on posttraumatic subdural hygroma are presented, with discussion of the development of the chronic subdural hematoma particularly. In all of these three cases the chronic subdural hematoma had occurred consequently to the posttraumatic subdural hygroma, but these diagnoses were done in variable periods of 20 days to 60 days. Therefore, it is suggested that the posttraumatic subdural hygroma have, at least, some relation to the genesis of the chronic subdural hematoma.

We aimed to evaluate the long term trantment of enalapril on the vascular response in the isolated aorta, and in anesthetized or pithed spontaneously hypertensive rats(SHR). In the isolated aorta, the increase in tension provoked by addition of KC1 16.7mM was attenuated by enalapril treatment(3mg/kg/day for 6 weeks), whereas the increment by addition of NE 0.1uM tension was not influenced. The frequency-dependent vasoconstricution induced by electrical field stimulation of aorta was also attenuated by enalapril treatment. In pithed SHR, the frequency-related hypertension provoked by electrical stimulation(10sec, 1ms with 40V) of sympathetic pregnglionic nerve was also attenuated by enalapril treatment. Neither dose-related vasorelaxation by acetylcholine addition in the aorta nor decrease of DBP by intravenously(i.v.)-injected aetylcholine was altered by enalapril treatment. However, beta2-agonist, salbutamol-induced vasorelaxation in enalapril-treated group, was more remarkable than that in control group. The hypotension by i.v.-but not by intracerebroventricularly-injected salbutamol strengthened by enalapril treatment. These results suggest that the suppression of development of hypertension by enalapril treatment may result from the reduction of adrenergic neurotransmission and activity to voltage dependent calcium channel by acting on vascular smooth muscle itself.

An analysis and CT findings in 21 adult patients of spontaneous intracerebral hematoma(SICH) mixed with CSF who were admitted to the Fatima Hospital from December 1986 to May 1989. The following results were obtained; 1) We could differentiated SICH that have inhomogenous density and thought that it is composed of blood, CSF and blood-CSF mixture. 2) Previously reported pathways that intracerebral hematoma rupture into the ventricle are caudate nucleus and thalamus but intracerebral hematoma can be mixed with CSF through the subarachnoid space of Sylvian fissure as an another route. 3) Intracerebral hematoma mixed with CSF was removed easily, safely and enoughly with simple aspiration method as like resoluted hematoma in subacute or chronic phase. 4) The prognosis of patients with SICH mixed with CSF was very good unlike to that of patients with pure intracerebral hematoma and/or ventricular hemorrhage.

Endoscopic retrograde cholangiopancreatography(ERCP) is a new diagnostic method for pancreatic and biliarydiseases which has been made possible by the development of fiberoptic duodenoscopy. It has been thought that ERCPwell serve an important role in the early detection of pancreatic cancer, but in order to detect minor lesions ofthe pancreas and improve the diagnostic accuracy of resectable pancreatic cancer, Endoscopic RetrogradeParechymography of the pancreas (ERPP) was developed recently. The authors analyzed 117 cases of ERCP performed atthe Kwangju Christian Hospital between Jan. and Dec. 1980, and compared them with the final diagnosis. The resultswere as follows; 1. Out of 117 cases, successful visualization of the duct of concern was achieved in 105 cases.Of these, 25 cases were ERPP. 2. The ratio of males to female was 1.44:1. Most patients were in the 4th to 6thdecade. 3. The commmonest clinical manifestations were upper abdominal pain (77cases), jaundice(23 cases),indigestion, vomiting and abdominal mass, in order of frequency. 4. Out of 46 cases of suspected pancreaticdiseases, the pancreatic duct was visualized in 36 cases, and 24 cases revealed pathognomonic findings. These werediagnosed as 16 cases of pancreatic cancer, 4 cases of chronic pancreatitis, 2 cases of pancreatic pseudocyst and2 cases of periampullary cancer with pancreas invasion. In pancreatic cancer findings were; encasement, localdilatation, delayed excretion, poor filling, obstruction of pancreatic duct, accompanying C.B.D. obstruction orstenosis and so called double duct sign. The chronic pancreatitis findings included; ductal dilatation (with orwtihout) obstruction, tortuosity with dilated saccular lateral branching, stone formation and the parenchymalfilling defect. 5. Out of 71 cases of suspected biliary tract diseases, the biliary tract was visualized in 57cases, and in 31 cases abnormalities were suggested; such as 20 cases of biliary stone, 1 cases of ascariasis, 1case of clonorchiasis with cholangitis, 1 case of clonorchiasis with stone, 2 cases of C.B.D. ca. 2 cases of G.B.ca, 3 cases of intrahepatic disease, 1 case of stones in the biliary tree with ampullary ca. 6. Complications ofERCP and ERPP were extremely raare. Transient abdominal distention, abdominal discomfort and elevated serumamylase were noted, but were not clinically significant.

The purpose of this study is to examine the initial reaction of craniofacial complex to the traction of headgears which are frequent used in clinical practice by using holographic interference method. Changes In the fringe pattern according to the traction conditions (outer bow length, load amount, direction) were compared. Human dry skull was used as experimental material, the results were as follows. 1. The density of fringes Increased with an increase in load. 2. Maxillary headgear affected circummaxillary bones-temporal bone, zygomatic bone, nasal bone, frontal bone, sphenoid bone as well as maxilla. 3. The most upward-backward displacement was observed in a high pull head gear (30degrees), this is though to be a optimal direction for supressing the growth of the maxilla.

This study was based on the study models of 32 subjects with normal occlusion, 40 with Class I malocclusion, 32 with Class II, Division 1 malocclusion and 38 with Class III malocclusion, aged 12 to 20 years (mean age 16.4 years). The purpose of present study was to define the difference between normal and malocclusion groups in maxillary dental arch palate. On the basis of findings of this study, the following results were obtained. 1. The intermolar widths and the intercanine widths in Class II, Div. 1 malocclusion group were smaller than in normal occlusion group significantly. 2. The arch lengths measured in both Class I and Class II, Div. 1 malocclusion groups were larger than in normal occlusion group. 3. The palates in Class I and Class II, Div. 1 malocclusion groups were longer and narrower than in normal occlusion, but the palates in Class III maloccusion group were shorter than in normal occlusion group significantly. 4. The palatal depths measured at level 1 in Class III malocclusion group were significantly higher than in normal occlusion and in Class II, Div. 1 group they were significantly higher than in normal occlusion at level 2 and 3. 5. The measurements of palatal areas at varions levels showed no significant difference between malocclusion and normal occlusion groups. 6. The palatal indice 1(palatal pength / palatal width) measured in both Class I and Class II, Div. 1 malocclusion groups were significantly greater than in normal occlusion and the palatal indice 2(palatal depth at level 1/palatal width) measured in all malocclusion groups are greater than in normal occlusion. 7. It was determined from findings of this study that the meaxurements of maxillary dental ardh and palate were influenced to a considerable extent by the molar relationship.

The salt-sensitivity has been generally accepted as a mechnism of high blood pressure in elderly hypertensive patients, and so it may result in a difference of renal handling of sodium and potassium between normal healthy control and elderly hypertensive patient. So to evaluate an lbove difference, the amount of 24 hours' urinary excretion of Na+ & K+ were measured in healthy normotensive control (10 case) and elderly hypertensive group(10 case) according to normal diet (12-15gm of NaCl) for first 3 days and low salt diet (3~5)gm of NaCi) for next 3 days, also blood rewwure was mintored. The results were followed : 1) 24 hours' urinary excretion of NA+ was increased in hypertensive group more than control group at first day of normal diet and low salt diet significantly. 2) After a replacement of normal diet to low salt diet, a maximal decrement of 24 hours' urinary excretion of Na+ was 25% at first day in control but 40% at second day in hypertensive group only. 3) There was a similar pattern of urinary excretion of K+ as Na+ in hypertensive group, but it was not stastically significant. 4) There was no significant changes of blood pressure, serum electrolyte and BUN/creatinine according to salt intake in both group. From above findings. We can conclude that a urinary excretion of sodium is delayed in elderly hypertensive group, and it is suggested that a delayed excretion of sodium. is associated with retention of sodium in body. So a persistent restriction of sodium is recommended in elderly hypertensive patient.

STUDY DESIGN: A case of brain infarction due to occlusion of vertebral artery after cervical spine fracture is reported. OBJECTIVES: Documentation of possibility and clinical significances of brain infarction as one of grave complications after cervical spine injury. SUMMARY OF LITERATURE REVIEW: Occlusion of vertebral artery and consequent brain infarction can be associated with cervical spine injuries because vertebral arteries course through the transverse foramina from sixth to second corvical vertebrae. Infarction of vertebrobasilar system may cause impairment of cerebral, cerebellar, or brain stem function and can occasionally bring grave functional loss, even death. MATERIALS AND METHODS: A case of occlusion of vertebral artery and consequent cerebral infarction after cervical spine fracture in a 66 year-old man. Brain CT and angiogram were performed. He was managed with anticoagulants. RESULTS: Neurologic deficits from brain infarction disappeared after 2 weeks. CONCLUSIONS: Attention to the possibility of these complications and awareness of their clinical features seem to be mandatory in managing cervical spine injury patients.

The purpose of this study is to see the value of transsectional morphology of polyethylene for evaluation of wear and characteristics of ultra-high molecular weight polyethylene. Retrieved nineteen polyeth- ylene tibial components were examined for this study. Ten components were the directly molded 1900 Himont polyethylene, and 9 components were the machined GUR 415 polyethylene. Transsection of polyethylene(thickness: 60 - 150 micron) was obtained by microtome and was examined microscopical- ly for the fusion defects, subsurface white bands, and delamination as a mode of wear. Significant differ- ences between two groups of polyethylene were found. Fusion defects greater than 100 micron were observed in 5 among 9 GUR 415 polyethylene. Subsurface white band were observed in 7 among 9 GUR 415 polyethylene. Delamination was found in 6 arnong 9 GUR 415 polyethylene. Neither fusion defects greater than 100 micron, nor delamination were observed in 1900 Himont polyethylene. Morphological examination of polyethylene section is an efficient way to differentiate the polyethylene and to evaluate the wear behavior of retrieved polyethylene. This study suggests that delamination of polyethylene tibial components is influenced by resin type and / or manufacturing method.
