During ideal physiologic occlusion in the intercuspal position, all molars are occluded simultaneously and each occlusal contact evenly transmits similar pressure. The purpose of this study is to analyze the occlusion in the mandibular bone fracture patients treated by open reduction. This patients were selected according to the following criteria: 1) complete dentition without any missing teeth, 2) relatively normal occlusion without original TMJ disorder. Occlusal analysis using T-scan system were performed in 22 patients and 20 normal subjects. Our results were followed: 1. The number of occlusal contacts and the magnitude or occlusal force were increased with time. (p<0.05). 2. In the unilateral mandibular fracture patients, occlusal force and occlusal contacts were increased with time on the both sides. 3. There was significant difference in the number of occlusal contacts and occlusal force between postoperative 1 month and normal group(P<0.05), but there was no significant difference in the number of occlusal contacts and occlusal force between postoperative 6 month and normal group(p>0.05).

30 patients with essential hypertension were treated with diltiazem (Herben(R))significantly decreased both systolic and diastolic blood pressuer and heart rate. Mean decrease in systolic & diastolic blood pressuer were 38.0+/-4,5mmHg and 16.3+/-2.3 mmHg respectively and mean drop in heart rate was 17+/-2 beats/mm. The side effects of diltiazem (Herben(R)) were mild headache, fatigue and pruritus, but those were insignificant. Diliazem may be of benefit to hypertensive patients, and particularly useful when hypertension occurs in association with coronary artery disease.

We observed the serum cholesterol, triglyceride and HDL-cholesterol values in 25 hyperlipidemic patients with procectofene(LIpanthyl(R))administration. 1) The mean serum lipids before & after procetofene administration was as follows 2) The undersirable effect of the drug was found on 3 patients; those were abdominal fullness, headache & pruritus.

Although ultrasonography replaced many invasive studies in biliary tract diseases, direct cholangiography does still play an important role in the diagnosis and management of choledocholithiasis. Endoscopoic retrograde cholangiography (ERC) is regarded as the best method in evaluation of exact extent of the disease and its frequent complication, cholangitis. Authors analysed 56 cases of choledocolithiasis diagnosed by ERC and compared these with ERC in 18 cases of normal, 22 cases of cholecystitis, 15 cases of clonorchiasis and 9 cases of parenchymal diseases of liver. The results are as follows; 1. ERC findings of choledocholithiasis are filling defects by stoneor stones, dilation of common hepatic as well as common bile ducts and findings of cholangitis. 2. ERC findings of cholangitis are dilatation of larger intrahepatic biliary radicles and acute peripheral tapering, decrease of arborization, increased or right angle branching pattern, straightening and rigidity as well as irregular narrowing of intrahepatic biliary trees. This findings are observed in majority of choledocholithiasis. 3. Over9mm in diameter at intraprancreatic portion of common bile duct was regarded as abnormal, with 95% sensitivity,85% specificity and 91% diagnostic accuracy by decision matrix analysis. 4. In the presence of dilatation of CBD and findings of cholangitis in ERC, one should consider choledocholithiasis in spite of absence of stone defect.

The advent of computerized cranial tomography represents a great advance in the diagnosis of very wide variety of intracranial lesions. The CT findings of acoustic neuroma have been reported by many authors, especially by Hatam in early contrast enhancement and evaluation of the internal auditory meatus. We have analysed 22pathologically proven cases of acoustic neuroma examined at the Kyung Hee University Hospital from Oct. 1977 to June 1981 and the results were as follows. 1. The sex ratio was 12 females to 10 males and the greatest number of cases (27%) were seen in fourth decade. 2. The precontrast CT scan of the tumor appeared as isodensity in 10 cases (46%), low density in 8 cases (36%) and high density in 4 cases (18%). The shape of tumor was round in 10 cases (46%), irregular amorphous in 9 cases (41%) and ovoid in 3 cases (13%). 3. The tumor was located at both anteriorand posterior sides of porus acousticus in 17 cases (77%), and only posterior side in 5 cases (23%), Associated hydrocephalus and intratumoral calcification were found in 18 cases (82%) and 1 case (4%), respectively. Bilateral involvement of the tumor was not seen. 4. In postcontrast CT scan, all of the acoustic neuromas but one, were enhanced and well defined. The most frequent enhancement pattern was heterogenous enhancement, seen in 10 cases (46%), but there was no specific enhancement.

Although the ultlrasonography has been regarded as a main procedure in the diagnosis of bile duct andgallbladder diseases, a few reports concerning the ultrasonographic findings of biliary ascariasis appeared in theliterature. Seven cases of real-time ultrasonographic diagnosis of biliary ascariasis were made in our hospitalduring last 15 months. In six, the diagnosis was confirmed by surgery or radiographic examination. The resultswere as follows; 1. The characteristic long, thick, highly reflective echo without distal acoustic shadowing inthe extra and/or in tra-hepatic ducts were seen in all six proven cases. 2. The echogenic, nonshadowing images ofthe worms were seen as single stripe in five cases(containing a central longitudinal, anechoic tube, suggestingits digestive tract in three cases ) or multiple stripes in one case. But so-called coiled appearance or amorphousfragments were not seen in our cases. 3. Associated findings were as follows; mild to moderate dilatation of theextrahepatic duct in all six duct in 1 case, intrahepatic stone in 1 case, contracted gallbladder containingsingle stone in 1 case and evidence of cholecystitis in 4 cases. 4. One false positive diagnosis of ascariasis inthe gallbladder is considered due to reverberation artefact. No false negative was seen.

A retrospective comparative analysis was made to assess the relative efficacy and advantage of computedtomograhy (CT) and ultrasound in the diagnosis of pancreatic lesions in patients wtih 33 various pancreaticdiseases. All patients underwent both CT and ultrasound examinations. CT has advantages in delineation ofmorphologic anatomy and its extent, and in identifying abnormal gas and calcification. On the other hand,ultrasound has advantages in evaluation of cystic lesion, pancreatic duct and bile duct. Authors recommendultrasound as a screeing test in the diagnosis of uncomplicated pancreatic duct and bile duct. Authors recommendultrasound as a screening test in the diagnosis of uncomplicated pancreatitis, pseudocyst and pancreatic cancerproducing jaundice, but recommend CT in the diagnosis of complicated pancreatitis, chronic pancreatitis andnon-jaundiced patient with susupected pancereatic cancer. Ultrasound has additional advantage in ultrasound-guidedaspiration biopsy.

Congenital tuberculosis is an infection that is established in the fetus by hematogenous spread or by the aspiration or inhalation of infected amniotic fluid either before or during labor. The diagnosis can be confirmed only if both the tuberculous nature of the lesion and the antenatal origin of the infection can be proved. The authors analysed roentgen findings of two cases of pulmonary tuberculosis, thought to be congenital; 1. Diffuse distribution of nodular densities and some confluent densities were seen in the entire lungs in the inital film.The pulmonary markings were decreased in some degree. 2. Air bronchogram was noted. 3. Hepatosplenomegaly was associated.
