Background: Univent(R) tube was designed to overcome the disadvantages of double lumen endotracheal tube for one lung anesthesia. But overinflation of the blocker cuff of an endobronchial tube can cause pressure damage to the bronchus. The purpose of this study was to evaluate whether the blocker cuff pressure and the duration of ballooning using the Univent(R) tube is correlated with the degree of bronchial mucosal damage (BMD). Methods: A total of 13 men and 7 women intubated with the Univent(R) tube were enrolled for the study. The BMD were evaluated by direct visualization using fiberoptic bronchoscopy prior to intubation and following extubation and the degree of the BMD were scored from 0 to 4 as follows; 0: normal, 1: erythema, 2: swelling, 3: hemorrhage, 4: mucosal wall tearing. Results: No change in bronchial mucosa (score 0) were observed in 11 patients (55%), erythema (score 1) in 5 patients (25%), swelling (score 2) in 3 patients (15%), hemorrhage (score 3) in 1 patient (5%) and mucosal wall tearing (score 4) is none in 20 patients. The bronchial blocker cuff pressure required to "just sealing" the bronchus was 178.1+/-37.4 mmHg with corresponding cuff volume of 6.7+/-1.0 cc. The duration of ballooning was 115.5+/-26.4 min. The correlation coefficient between the blocker cuff pressure and duration of ballooning to the degree of bronchial mucosal damage were 0.125 and 0.137, respectively, which was not statistically significant. Conclusions: The bronchial blocker of Univent(R) tube doesn't cause any severe BMD and the degree of BMD are correlated with neither the bronchial blocker cuff pressure nor duration of ballooning of Univent(R) tube.

There are many established roentgen signs of ascites such as hepatic angle sign, generalized graying of the abdomen, frog belly appearance and Hellmer's sign. These signs are easily recognized in the standard flat abdomen film. It is however hardly possible to recognize such signs in small films of double contrasted upper GI series. By a retrospectroscopical observation we were able to find some interesting signs of massive ascites in small size films of double contrasted stomach and duodenum of upper GI series. The clinical materials consisted of 27patients with massive ascites and 30 normal subjects. The signs we observed were ;(1) Constriction deformity of the junction of the fundus and body of the stomach. We named this "waist" sign. This constriction was attended by convergence of mucosal folds. We called this "converging folds" sign. (2) The fundus assumed electric bulbappearance with its long axis directed vertically. We called this "electric bulb" sign. In normal subjects the fundus assumed beret-cap like appearance. These signs were only appreciated in the supine and RAO views and not in other views. Of these new signs of massive ascites where fundic view was obtained in supine or RAO position.

The increased incidence of the trochanteric fracture of the femur was accompanied by the development of the vehicle and the prolongation of the average life-span. Recently it has been also increased in an active person from thirties to forties. 87 cases of the trochanteric fracture of the femur in 86 patients who have been admitted and treated at the Department of Orthopedic Surgery of Hanyang University Hospital during 8 years and 10 months, from May, 1972 to February, 1981, were reviewed. The results of this study were as follows: 1. The trochanteric fracture of the femur was more common in male and was frequent in a person who was from thirties to forties and who had vigorous social activity. 2. An injury from traffic accident was the most common cause of the fracture from thirties to forties and an injury from slip down was most common in seventies. 3. The unstable fracture which was classified by Evans' classification, Boyd and Griffin Type II Fx. and Tronzo Type III Fx. were most common in the intertrochanteric fracture and the Fielding Type II Fx. was most common in the subtrochanteric fracture of the femur. 4. Other injuries were accompanied by the trochanteric fracture of the femur in 38 patients (44.2%) and the pelvic bone fracture was the most common associated injury in these patients. 5. The weight bearing was allowed earlier in the patient who had been given the surgical Tx. than in the patient who had been given the conservative Tx. 6. In adults, there was no significant differences in the duration to achieve the bony union between the conservative treatment and surgical treatment performed. 7. We considered that the diminution of the probable complications by early weight bearing after accurate open reduction in accordance with the Type of the Fx. followed by secure internal fixation with devices is an ideal method of the Tx.

Dermatophytes infect the human hair, skin, nail and cause the dermatophytosis. The extracellular and intracellular proteinases of the dermatophytes commonly occur in the genus Trichophyton like T. rubrum, T. mentagrophytes, and T. granulosum. These enzymes play a prominent role in growth, multiplication and infection of the host tissue. Extracellular proteinases have been purified from the species of Trichophyton and Microsporum. We purified the proteinase partially from the culture filtrate of the Trichophyton tonsurans through Mono-Q and Superose 12 column and investigated its biochemical and enzymatic characters. The molecular size of the proteinase was estimated to be 41 kDa by SDS-PAGE. And pI was 3.2. The optimal temperature and pH for an enzymatic activity were 27C and 7.5, respectively. The purified porteinase degraded the keratin, bovine serum albumin, hemoglobin. The serine proteinase inhibitor like PMSF and DFP inhibited the proteolytic activity of the purified enzyme whereas the cysteinase inhibitor did not. These results demonstrated that the purified proteinase is a serine proteinase and can contribute the tissue invasion.

To investigate relationship between alpha1-acrenoceptors and nicardipine, an 1,4-dihydropyridine calcium antagonist, effects of nicardipine, on phenylephrinne(PE)-induced vasoconstriction in isolated arterial rings and pressor response of rabbits were observed. In normal physiological salt solution(NPSS), 35mM KCI produced persistent contractions of thoracic aorta and carotid artery and the contractions were dose-dependently inhoboted by cumulative admini-stration of nicardipine in the range of doses from 10(-10)M to 10(-4)M, IC50s of nicardipine in the thoracic aorta and carotid artery were 3.3x10(-7)M and 4.6x10(-7)M, respectively and there was no difference between both values. Constant contractions induced by 10(-5)M PE in both rings were inhibited by the same doses of nicardipine in a dose-dependent fashion. The IC50s were 2.8x10(-4)M in thoracic aorta and 2.9x10(-5)M in carotid artery respectively, and the former was about 10 times greater than the latter. In Ca2+ free PSS, KCI did not produce any contractionn. Though constant and reproducible in NPSS, PE-induced contraction was transient and not reproducible in Ca2+ free PSS. The contraction in both rings were weakened to about 70% of those in NPSS. Pretreatment with nicardipine in the range of doses from 10-8M to 10-5M hardly affected the PE-induced contraction and the largest dose 10(-4)M slightly inhibited the contraction. Intravenous injection of nicardipine 10 to 1000microg/kg decreased blood pressure and heart rate of rabbits in a dose-dependent manner. The % decrease of heart rate was much smaller in comparison with the %decrease of blood presseure. Pressor effect of 30microg/kg PE was dose-dependently inhibited after treatment with nicardipine 10 to 1000microg/kg and ID50 was 314microg/kg(6.1x10(-7)mole/kg). Above results suggest that nicardipine blocks extracellulr Ca2+ influx by membrane depolarization and in a part by alpha1-adrenceptors, then relaxes arterial smooth muscles in rabbits.

Higt energy electron beam therapy is a method which is used for the treatment of superficial tumors (less than 5 cm deep) with a characteristically sharp drop-off in dose beyond the tumor. This method offers distinct advantages in dose uniformity and in minimizing the dose to deeper tissues. We report herein three cases of epithelial skin cancer treated with high energy electron beam. The first patient was a 79-year-old male who had primary basal cell carcinoma(BCC) on the right lateral canthus. The second patient was a 67-year-old male who had recurreiit BCC on the right cheek. Both of them received electron beam therapy on the lesion and there were no clinical relapse signs over 1 year. The third patient was a 46-year-old male who had squamous cells, carcinoma on the lower lip. He also received electron beam therapy on the lesion, but it recurred.

Oral cholecystography is one of the most relible and widely used x-ray examination which enables us to observe not only morphological features of the gallbladder (GB) but also its functioning state. It was disclosed that functional evaluation of the GB is mandatory to recognize such kinetic disorders of the viscus as acalculous cholecystitis or dyskinesia. For the purpose of functional evaluation, fat meal has been used traditionally. Recently, cholecystokinin(CCK) and ceruletide were introduced into clinical diagnosis of the GB, the usefulness of which we have confirmed. In the present study we have made an attempt at improving cholecystagogic effect of conventional fat meals(FM) such as whole mild and egg yolk by changing the posture of the examined from sitting up to right decubitus position after the ingestion of fat meal. The hypothesis involved in this study is that the presence of quantitatively more fat meal in the duodenum per unit time may result in more effective cholecystagogic action and such a setting would be created by enhancement of pyloric passage of fat meal by decubitus posturing. Clinical materials consisted of 280 normal oral GB series (136 males and 144 females) andthey were divided into 4 equally numbered groups of mild sitting and mild decubitus and egg sitting and eggdecubitus. Upon confirming satisfactory opacification of the GB 11 hours after the ingestion of 3g of sodiumipodate or iopanoci acid either 2 pieces of medium sized hen's egg yolk were given. The xaminess were then allowed either sitting up comfortably on a bench or lying down on the right flank on a couch. After the ingestion of fat mean, x ray was taken at the end of 30 minutes in all but the mild decubitus group in which x rays were taken serially at the end of 5, 15, 30 and 60 minutes. The frontal area of each opacified GB was measured by using aplanimeter and the contraction rate before and after fat meal stimulation was calculated by the following equation and delineation of the biliary tree was analyzed in each group. Contraction rate (%) = (1

The technic of selective transbronchial brush biopsy has been described by authors in a number of medialcenters. The procedure was popularized by Fennessy. This procedure should be considered for any hospital that isprovided with an image intensifier and adequate laboratory facilities. Between May and Aug. 1982, 13 patientsunderwent transbronchial brush biopsy at the Department of Radiology, St. Mary's Catholic Medical College. In mostcases, biopsy was performed was perforemd because of the presence of a pulmonary lesion or lesions suspicious ofmalignancy or infection in which cytologic and bacteriologic tests had failed to establish a diagnosis. Our recentclinical experience forms the basis of this communication. 1. As a reulst of bronchial brush biopsy, 4 cases ofpulmonary tuberculosis, 1 case each of alveolar cell ca, small cell ca, undifferentiated ca, and 3 cases ofbacterial pneumonia could be positively diagnosed. 2. The complications are transient hemoptysis and fever in 1case. 3. Bronchial brush biopsy has been proven to be a safe procefure with a high yield in the cytologic andbacteriologic diagnosis of diseases of the respiratory tract.
