PURPOSE: This study was designed to evaluate usefulness of intravenous digital subtraction angiography (IV-DSA) in detection of peripheral arterial obstructive disease(PAOD) and in follow-up of percutaneous transluminal angioplasty(PTA). MATERIALS AND METHODS: 35 Patients who had clinical symptoms and signs of compromised lower extremity perfusion, was screened with IV-DSA and then performed confirmative conventional angiography. We obtained sensitivity, specificity and accuracy of IV-DSA by comparing the findings of IV-DSA with those of conventional angiography. 21 patients who had been performed successful PTA, were foliowed-up with IV-DSA in 3, 6, 12months. We studied patency rate and factors that influenced restenosis. RESULTS: The sensitivity, specificity and accuracy of IV-DSA were 100%, 97%, 97% in lilac artery, 92%, 96%, 93% in femoropopliteal artery, 85%, 75%, 70% in proximal tibioperoneal artery retrospectively. IV-DSA follow up after PTA showed patency rate of 67% in first 3month, 67% in 2nd 3month, 60% in next 6month. Longer length and more irregular surface of the stenotic site, and higher incidence of run-off of vessel and of residual stenosis in the patients with restenosis were noted. CONCLUSION: High sensitivity, specificity and accuracy of IV-DSA in evaluating PAOD suggest that IV-DSA is useful in screening, planning therapy and following up after PTA.

From January to December 1984, 191 patients with associated ventricular septal defect(VSD) were studied in the cardiac cathetherization laboratory. Among theses 191 cases, 58 cases(30.4%) of subpulmonic VSD were identified by angiocardiography. Among the 59 cases of subpulmonic VSD, 12 cases(20.6%) were complicated with aortic infficiency(AI). The relative frequency of subpulmonic VSD increased with the increase of age and the frequency of complication of AI with the subpulmonic VSD also increased with the increase of age. The amount of left to right shunt in the patients with subpulmonic VSD and AI was small and Qp/Qs ratio was less than 2.0 in all of the 12 cases. Among the 12 patients 4 cases had a pressure gradient greater than 20 mmHg across the infundibular region of the right ventricle.

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.

Endogenous nitric oxide (NO) has been known to regulate the salivary secretion and glandular blood flow. However, the distribution of nitric oxide synthase (NOS) responsible for NO synthesis has not been well studied in salivary glands. The present study was aimed to investigate the distribution of nitric oxide synthase isoforms (endothelial, neuronal, and inducible NOS). Immunohistochemistry, using monoclonal mouse anti-endothelial NOS, anti-neuronal NOS, and anti-inducible NOS, was performed in 3 major salivary glands (parotid, submandibular and sublingual gland) of the rat. Endothelial NOS (eNOS)-positive immunoreactivity was observed in arterial endothelium, striated duct, granular convoluted duct of the submandibular gland, intercalated duct, and mucous acinar cells of the sublingual gland. The eNOS-positive immunoreactivity was most prominent in the arterial endothelial layer and that of the striated and granular convoluted duct was well concentrated in columnar epithelial layer. In the intercalated duct and mucous acinus, eNOS-positive immunoreactivity was weakly detected. Neural NOS (nNOS)-positive immunoreactivity was observed in submandibular ganglion, autonomic postganglionic fiber, striated duct, granular convoluted duct, and intercalated duct. nNOS-positive immunoreactivity of the submandibular ganglion and autonomic postganglionic fiber was most prominent and that of the ductal system was well concentrated in the epithelial layer. eNOS-positive immunoreactivity was not detected either in excretory ducts or in serous acinar cells. Inducible NOS-positive immunoreactivity was not detected. There results reveal the presence of eNOS and nNOS in the salivary gland, which may be related with regulation of the glandular secretion and blood flow through synthesis and secretion of NO.

Although halothane is one of the most widely used inhalational anesthetics, it may cause postanesthetic complications such as halothane hepatitis. Halothane hepatitis has been reported lintermittently since 1958 with variable incidence. Changes in hepatic functions by halothane hepatitis are usually mild and reversible but they may be fatal it the patient had already shock, sepsis, massive blood transfusion, previous hepatic disease, hypoxia or induction of microsomal enzyme system. Hepatitis due to blood transfusion has high incidence especially in Korea where 10~20% of all population has vital hepatitis. Most of transfusion hepatitis is also mild but it may progress to chronic condition and eventually death. We experienced 2 cases of fulminant hepatitis after operation. Several factors such as massive whole blood transfusion, upper abdominal trauma, inhalational anesthetic agent, induction of microsomal enzyme system and shock might be attributed to development of the fulminant hepatitis.

Isolated masseter spasm after succinylcholine administration is a rare abnormal response, but has been reported by a number of authors and is considered and early manifestation of malignant hyperpyrexia. We experienced a isolated masseter spasm after a small dose of succinylcholine administration in a facial palsy patient of central type due to brain tumor. It was likely that the intensity of this spasm was dose dependent to the amount of succinylcholine administration, and the spasm was prevented by pretreatment of nondepolarizing muscle relaxant. Anesthesia was performed safely for about 5 hours with nitrous oxide and halothane. We considered that this spasm was due to supersensitivity appearing at the denervated muscle.
