The purpose of this study was to evaluate the characteristics of craniofacial skeleton on orthognathic surgical cases with skeletal Class III malocclusion. For this study, 74 students at the dental college of Chosun University volunteered as a normal occlusion group. They had well-balanced faces and good occlusions with acceptable Class I molar relationship. They had not received orthodontic treatment and had no signs or symptoms of temporomandibular joint dysfunction. 45 malocclusion patients enrolled for orthognathic surgical treatment with skeletal Class III malocclusion at the Department of Orthodontics, College of Dentistry, Chosun University. On the basis of this study, the results of this study were as follows: 1. Skeletal Class III malocclusion was largely due to the overgrowth of mandible in man and the undergrowth of maxilla in woman. 2. The mandible was antero-inferiorly overgrown by large MP-HP angle and large gonial angle in orthognathic surgical cases with skeletal Class Iii malocclusion. And also, upper incisors were severely labioversioned, but on the other hand lower incisors were linguoversioned. 3. In female, lower-third facial height was characteristically shortened in comparison with middle-third facial height and also, lower facial throat angle was sgrall in male.

Thelazia callipaeda, parasitic in the eye of 24 years old Korean male, was extracted from the left eye of the patient in Seoul, Korea. We confirmed that as T. callipeada morphologically, based on the descriptions of Hsu and other literature. We presents the 7th human thelaziasis case in Korea with the historical review of the literature.

Renal compensatory growth, after the loss of functioning parenchyme due to nephrectomy or hydronephrosis, is an important clinical phenomenon which often eventually results in glomerulosclerosis and renal failure. Thus numerous efforts have been made to elucidate the mechanism of compensatory growth and to discover the methods which can impede the compensatory process. Compensatory renal growth in mature animals is mainly by cellular hypertrophy, the increase in cellular component without increase in number of cells. But small portion of growth is composed of hyperplasia, the increase in total number of cells. To evaluate hyperplasia and hypertrophy, flowcytometry is employed. The DNA ploidy pattern of each kidney cell is analyzed, and the proportion of synthetic and replicating cells is calculated. For evaluation of hypertrophy, the presumed causative metabolite, nitric oxide, is indirectly titrated by measuring the activity of its key enzyme, nitric oxide synthase. The results of the experiment are as follows. 1. The increase in fraction of synthetic and replicating cells in flow cytometry is a definite evidence of cellular hyperplasia, thus hyperplasia is involved in neonatal compensatory renal growth. 2. Cellular hyperplasia is profound after 48 to 72 hours of injury 3. A statistically significant difference was noted at 12 hours after nephrectomy between control and experimental groups in G, + M phase (mitotic phase). 4. Nitric oxide is an important messenger of early (within 48 hours) renal compensatory growth in neonatal rats. 5. In view of the adult model experiment of nitric oxide synthase, where nitric oxide is confirmed to be involved in renal compensatory hypertrophy, nitric oxide is also related to the renal hypertrophy in neonatal periods. In conclusion, the compensatory renal growth in neonatal period is due to both hyperplasia and hypertrophy. Nitric oxide is a key signaling messenger of early compensatory renal growth, it can be stated that if the process of hypertrophy could be selectively blocked, prevention of renal failure as a consequence of glomerulosclerosis can be a reality.

BACKGROUND: Primary hepatocellular carcinoma(HCC) is the second cause of cancer death in our country. Hepatitis B virus(HBV) and hepatitis C virus(HCV) are important risk factors for hepatocellular carcinoma. The mechanism of HCC development and the epidemiology in HCV infected individuals are still unclear. In this study, we investigated the epidemiolgical and clinical features of HCC in relation to viral infection. METHODS: We reviewed the medical records of 160 HCC patients retrspectively who had been admitted to one University Hospital located in Seoul between January 1991 and December 1995. Among these patients, 113 patients were positive for HBsAg(B group), 24 for anti-HCV(C group). We compared epidemiological and clinical data between B group and C guoup. RESULTS: Anti-HCV positivity was significantly higher in HBsAg negative patients than in HBsAg positive patients(53.3:1.7%, p<0.01). The mean age of patients in B group was significantly lower than that in C group(52:62yr, p<0.01). In C group, the proportion of Child-Pugh class B and C was significantly larger than that of B group(35.4: 75.0%, p<0.01). In C group, the proportion of transfusion history was significantly larger than that in B group(4.4: 16.7%, p<0.05), and the proportion of drug abuse hestory was significantly larger than that in B group (31.0:62.5%, p<0.01). In C group, the albumin, cholesterol, Gamma-glutamyl transferase leves were significantly lower than those in B group. In B group, the proportion of metastasis was significantly larger than that in C group(31.9:4.2%, p<0.01). Alpha fetoprotein levels greater than 400ng/ml are much more prevalent in group B significantly(67:39.1%, p<0.05). No significant differences in cumulative survival rate(1yr, 2yr) and median survival time were observed between the two groups. CONCLUSIONS: We ascertain that the HBV and HCV are inportant factors in HCC. In epidemiology and clinical features of HCC, there were some difference between the HBsAg and anti HCV positive group. Therefore, on primary health care settings, it is necessary to test for hepatitis C as well as hepatitis B in order to prevent and manage HCC and chronic liver desease.

We report a patient with progressive supranuclear palsy (PSP) with his serial photographs before the onset of ocular symptoms and after the onset with two year intervals. These photographs show his progressive eyeball deviations toward complete exotropia. There were no effective voluntary eyeball movements, Bell's phenomenon, doll's eye movements, and vestibulo-ocular reflexes. These signs indicate the involvement of the oculomotor nuclear complex by the disease. We suggest that PSP may cause not only 'supranuclear' but also 'nuclear' complete ophthalmoplegia with exodeviation of the eyes.

Chondroblastoma is a rare primary bone tumor which originates from cartilage, and represents approximate 1% af all bone tumor. The chondroblastoma arises most frequently from the epiphysis of the long bones with the humerus being the commonest site. It afflicts usually the young under 25 years with greater incidence in male. As there is no cartilage cell on craniofacial bone which is mainly fromed by intramembranous ossification, the chondroblastoma on the craniofacial bone is extremely rare. But the chondroblastoma recurred frequently in craniofacial bone when the mass is excised incompletely or curretted and, as the tumor has the outstanding ability of local invasiveness, it destructs the adjacent bone. In addition, it is difficult to diagnose differentially from sarcoma or giant cell tumor histopathologically. Due to the entities described above, it is necessary to remove the entire tumor mass as complete as possible, to treat with radiation pre or postoperatively for preventing from recurrence, and to observe for a long time. The chondroblastoma on temporal bone is rare and is difficult to diagnose and treat successfully. So we'd like to present a case of chondroblastoma which was originated from temporal side of TMJ with literatural review.

A total of 181 cases of industrial ocular injuries hospitalized and treated at the St. Mary's Hospital, Seoul during the 5-year period was studied on their epidemiological characteristics. Of there patients 96.7% were males, and 43.6% were in twenties, 49.7% of the cases were injured on left eyes. There were no statistically significant differences in frequencies of study subjects by day of the week and month of the year. Most common injury hour were between 10- < 12 AM(13.6%) and between 2- < 4 PM(20%). Of the total 101 cases, 37.6% were working less than 6 months, and 73.7%, less than 2 years. Of the total, 42.3% were involved in machinery work and 13.9%, in construction work. According to the American National Standard Method of recording basic facts relating to the nature and occurrence of work injuries, 62% among all source of injuries was metal item and the most common accident type was struck by flying objects(76.2%). Among 181 cases, only 2 cases wearing protective equipment when the accidents occurred.
