The authors analyzed retrospectively the 36 patients with malignant salivary gland tumors who were treated at Department of Oral and Maxillofacial Surgery, Pusan National University Hospital from February, 1989 to September, 1997. The results obtained were as follows: 1. There were 14 males( 38.9%) and 22 females(61.1%). The peak age of patients with major salivary gland tumors was the 6th decade, but with minor salivary gland was the 5th decade. 2. Of all salivary gland tumors, 5 cases arose in the parotid glands, 2 cases in the submanibular glands, 1 case in the sublingual gland and 28 cases in the minor salivary glands. 3. The incidence according to the anatomic primary site for minor salivary glands was 15 cases in the palate, 5 in the floor of mouth and 2 cases each arising in the tongue, lip, retromolar area and buccal mucosa. 4. Of all salivary gland tumors, adenoid cystic carcinoma was 5 cases in the major salivary glands and 8 in the minor salivary glands. mucoepidermoid carcinoma was 2 cases in the major salivary glands and 14 in the minor salivary glands and others were 2 cases of adenocarcinoma, 4 malignant mixed tumors and 1 undifferentiated carcinoma. 5. The incidence of cervical lymph node metastasis was 100%(2/2) in the submandibular glands, 80%(4/5) in the floor of mouth, 50%(1/2) in the tongue and 20%(1/5) in the parotid glands. The highest incidence of lymph node metastasis according to histopathological classfication was found in the high grade of mucoepidermoid carcinoma and tubular type of adenoid cystic carcinoma. 6. Nerve invasion was common in the adenoid cystic carcinoma. 7. The lung was the commonest site for distant metastasis comprising 7 cases among 7 cases in which distant spread occurred.

We encountered the danger of the bleeding the vertex and posterior fossa epidural hematoma(EDH) operation which were related with large sinuses. Traumatic vertex EDH and posterior fossa EDH were usually accompanied by the fractures of coronal, sagittal suture or occipital bone. And frequently, sources of the bleeding were venous sinuses or fracture site. The patients who had vertex EDH were paraparetic soon after injury and the patients who had posterior fossa EDH were dangerous due to brain stem compression. We treated successfully the 13 patients who had vertex EDH(7 patients) and posterior fossa EDH(6 patients) by the method of one or two burr holes and urokinase irrigation. The authors represented this method may occasionally be preferable to craniotomy for these lesions. Advantages of the methods were : 1) More simple, cosmatic procedure and no need of cranioplasty. 2) Reduced operation time and morbidity. 3) Enable to operate under local anesthesia. 4) Reduced rate of delayed intracranial hematoma due to acute decompression of epidural hematoma. 5) Reduced the date of admission. 6) Possibly, prevention of rebleeding and air embolism.

PURPOSE: This study observed the changes in the telomerase activity, it's developmental regulation, PCNA expression, and their correlation in rat's upper digestive organs during growth and aging. MATERIALS AND METHODS: Upper digestive organs(buccal mucosa, gingiva, palate, submandibular and parotid glands, and tongue) were aseptically removed from Sprague-Dawley rats of fetal(gestational 20 days), growing(1, 2, 3, 5, and 7 weeks after birth) and adult(12 week old). Samples for telomerase activity were frozen on liquid nitrogen immediately after sacrifice, and stored until the use at -75 degree C in order to measure it. Telomerase activity was measured by a PCR-based telomeric repeat amplication protoco(TRAP) assay and quantitated with Photometric Telo TAGGG Telomerase PCR ELISA plus(Roche Diagnostics GmbH. Mannheim. ermany). PCNA expression were measured immunohistochemistry with anti PCNA Ab-1, Clone PC10(NeoMark. California. USA). RESULTS: 1. Telomerase activities in buccal mucosa, palate and gingiva were the highest in fetus and decreased gradually or rapidly after birth and then diminished, but In salivary gland and tongue were the highest in fetus and also high at 1 week and then decreased rapidly. 2. PCNA expression in buccal mucosa, gingiva, Tongue and salivary gland was the highest in fetus and decreased gradually and then diminished. but only in palate decreased rapidly after birth and then diminished. CONCLUSION: The highest telomerase activity of embryonic stage decreased rapidly after birth in rat's upper digestive organs. There may be a developmental regulation of telomerase activity, but not a tissue-specific. This telomerase activity seems correlated closely with PCNA expression in rat's upper digestive system.

Thrombolysis using urokinase solution is one of the effective methods in treatment of intracerebral hematoma. The present study was undertaken in order to 1) determine the most effective concentration of urokinase solution, 2) determine the most suitable time interval of irrigation of urokinase solution through the measurement of hemoglobin and FDP(Fibrin / Fibrinogen Degradation Product) of drained solution, 3) estimate the size of unresolved hematoma without taking brain CT. The results are summarized as follows : 1) The most effective and economic concentration of urokinase solution was 1000 u/ml. 2) The most preferable time interval of irrigation of urokinase solution was about one hour. 3) It was possible to estimate the size of unresolving hematoma by means of measurement of hemoglobin and hematocrit of patient, hemoglobin and volume of the thrombolysed solution, so that it was unnecessary to take brain CT for measurement of remaining hematoma.

OBJECTIVE: Our purpose was to describe the clinical progress and the maternal and fetal outcome in 16 pregnancies complicated by the HELLP(hemolysis, elevated liver enzymes, low platelet). Material: We reviewed the maternal and neonatal charts from 16 consecutive pregnancies complicated by the HELLP syndrome among 302 pregnancies complicated by preeclamsia and eclamsia managed at our hospital during the period of 4 years from June 1994 through June 1998. The HELLP syndrome was defined by previously published laboratory criteria. We assessed the time of onset, presenting symptom, laboratory finding, mode of delivery, fetal and maternal complication in each case. We also reviewed the clinical finding in detail in the case resulted in maternal death. RESULTS: In regards to the time of onset, 15 cases (93.7%) occurred at antepartum period and only 1 case (6.2%) occurred at postpartum period. Among the 15 cases occurred at antepartum period, 13 cases (81.25%) developed at 27 to 36 weeks gestation and 2 cases (12.5%) developed at near term. In regards to the presenting symptom, twelve patients (75%) complained of right upper quardrant or epigastric pain. Of 16 patients, 12 patients (75%) experienced headache and 10 patients (62.5%) complained of nausea, or vomiting and 5 patients (31.2%) had visual disturbance. The laboratory finding of all 16 cases were as follow; the mean level of platelet: 68700/mm3 (range: 48000 to 91700), the mean level of serum asparate aminotransferase: 335 IU/L (range: 62 to 135), the mean level of lactic dehydrogenase: 910 IU/L (range: 558 to 5794), and the mean level of total bilirubin: 2.6 mg/dl (range: 0.7 to 10.4). To review the mode of delivery, cesarean sections were done on 10 patients (62.5%) including 7(43.7%) emergency and 3(18.7%) elective operations. However, 6 patients (37.5%) delivered vaginally. Maternal complications were as follow; abruptio placenta in 1 case (6.2%), DIC in 2 cases (12.5%), pulmonary edema in 3 cases (18.7%), pleural effusion in 4 cases (25%), renal failure in 4 cases (25%), and 1 case of death. Fetal and neonatal outcome was assessed; 9 cases of intrauterine growth retardation (56.2%), meconium stained in 3 cases (18.7%), 2 stillbirth (12.5%), and 2 neonatal death (12.5%). CONCLUSION: HELLP syndrome is associated with serious maternal and fetal morbidity and mortality.

OBJECTIVE: To determine whether hysterectomy by the vaginal route is safe and feasible in patients with previous pelvic operation. METHODS: A retrospective study of the records of Hallym University Hospistal patients who underwent vaginal hysterectomy performed by the senior author. Between January 1990 and January 1997, 212 patients who had previous pelvic operation were studied with special reference to operative difficulties, previous operation type, intraoperative complications, surgical time, hospital stay. RESULTS: 1. Patients characteristics was that ; The average age was 44.5+/-6.6 years old, the average parity was 2.3 , the average stay of hospitalization was 7.5+/-0.89 days, the frequency of Morcellation was in 24.5%, the average surgical time including associated procedure was 82+/-16.2 minutes, the average uterine weight was 164+/-85.1gm. 2. The most common previous pelvic operation was cesarean section(95 cases). 3. The most common indication was uterine myoma(51.9%). 4. Surgical technique used to gain access to the pouch of Douglas was done anteriorly; 52 patients of previous cesarean section(24.5%) and 112 patients of others operation(52.8%) were easily opened by blunt dissection, 43 patients of previous cesarean section(20.3%) and 5 patients of others operation(2.4%) were required sharp dissection. posterioly ; 190 patients(89.6%) were easily opened by blunt dissection, 22 patients(10.4%) were required sharp dissection. 5. Significant complications were bladder injury(1 case) , postoperative transfusion due to bleeding(6 cases). No cases of postoperative laparotomy was done and other minor compications were fever(15 cases), bladder retention(11 cases), others. CONCLUSIONS: It was possible to perform vaginal hysterectomy safely in patients with previous pelvic operation. Vaginal hysterectomy remains the method of choice for removal of the uterus of the previous pelvic operations in the absence of other contraindications.
