Background: The end-tidal carbon dioxide tension(ETCO₂) is defined as a partial pressure of carbon dioxide at the end of an exhaled breath. The purpose of this study is to determine the correlation between ETCO₂and arterial carbon dioxide tension(PaO₂) in nonintubated patients with respiratory distress in emergency department(ED). Methods: A prospective non-blind study was performed in ED of our university hospitals. Participants included all nonintubated adult patients with respiratory distress requiring arterial blood gas analysis. ETCO₂was measured with a capnography monitor during tidal volume breathing. ETCO₂were recoreded at the time of arterial blood gas sampling. The correlation between ETCO₂and PaCO₂was analyzed in all patients and in subgroups by simple linear regression. Results: Sixty patients were enrolled. In all patients, ETCO₂was 5.72mmHg lower than PaCO₂and correlated well with PaCO₂(r²=0.716). ETCO₂correlated best with PaCO₂in patients who were either acidotic or non-smoking. Conclusion: ETCO₂correlate well with PaCO₂in nonintubated patients with respiratory distress in ED. ETCO₂may be sufficient to reflect PaCO₂in selected patients and obviate the need for repeat arterial blood gas determination.

A cytochrome C - specific protein methylase Ⅲ was purified approximately 63 - fold from Saccharomyces cerevisiae. The unmethylated cytochrome C served as substrate for the enzyme. Horse heart apocytochrome C was found to be a better substrate than the native horse heart cytochrome C. This observation suggests that the in vivo methylation of cytochrome C in the yeast probably occurs before cytochrome C become attached to the mitochondria. In partly purified protein methylase Ⅲ the optimun pH is about 9.0, the enzyme activity is linearly proportional to the amount of enzyme protein up to about 30㎍ and also to time up to 15min. The Km values for horse heart cytochrome C and S - adenosyl - L- methionine were 1.33mM and 40㎛, respectively. S - adenosyl - L - homocysteine was found to be a competitive inhibitor for S - adenosyl - L - methionine, and the Ki value was 2.7 μM. The molecular weight of the enzyme was approximately 97,000, determined on sephadex S- 200 gel filtration. The regulation of cellular cytochrome C and the protein methylase Ⅲ are not coordinately related in a parallel manner.

최태운,김돈,이세종 慶星大學校 1991 論文集 Vol.12 No.3

We supposed that doping effect of KCIO�on YBaCuO mainly comes from ?? ion. Potassium was vaporized during the sintering process and oxygen in KCIO� did not improved the superconductivity. Doping effect was investigated with XDR, iodometric titration, resistivity measurement and SEM. Due to the formation of non-superconducting phase between superconducting grains, and interruption of superconducting path by ?? superconducting transition temperature was decreased from 94K to 90K.

Ameloblastoma is most commonly occuring odontogenic tumor in oral cavity. The biologic behavior of this neoplasm is a slowly growing, locally invasive tumor with a high rate of recurrence, therefore malignant neoplasm is defined clinically. Surgical procedures of the ameloblastoma is classified curettage, enucleation, marginal resection, segmental resection, and hemisection. Treatment method, recurrence rate, and prognosis are different depending on the clinical type of ameloblastoma. We experienced recurred ameloblastoma in mandibular edentulous area after conservative operation. This is a report of a case about 41-year-old female patient with recurred ameloblastoma on mandible body treated by marginal resection and autogenous iliac bone graft. We present the case with review of literature.

The purpose of this study was to research the change of the forest in Myungseo-lee Sanchuk-myun, Chungju where most of the area managed the Swidden Agriculture(Shifting cultivation). The mountainous district should be used and developed the multi-purposing source among the agricultural field, grassland, forest, a recreational area, and an industrial site, and should be presupposed the establishment of synthetic and efficient change system. This study began to pay attention to observe the peculiarity of Swidden Agricultural area in terms of forest aspects and to broaden the outlook of Swidden Agriculture. In the status of Myungseo-lee, prior to the Project to Rehabilitate the Illegal Swidden, from 1973 to 1976, the private forest gets 110.9ha (23ha for Seodae-village, 26ha for Dooduk-village, 6ha for Myungdol-village, 41ha for Chungam-village, 14.9ha for Pangdae-village). In Myungseo-lee. millet and corn were harvested, and they performed the rotation of planting and temporary resting by changing the field. The cultivated acreage per a house of total 5 villages in Myungseo-lee was just 0.4ha in average. The 70ha of the Swidden in Dooduk-village. Myungseo-lee, was sold to the Miwon corp. and the 342ha of that in Myungseo-lee was sold to Seohae-devlp.(SK forest). Those areas afforested. As the regulation plan for the Swidden began, the people in the site got paid for 300,000won as a migration fee. The special feature of the Swidden in Myungseo-lee was that the whole migration village was already established before the regulation plan for the Swidden began, and the yield was harvested by more than other villages the use of chemical fertilizer. And, in the Swidden agriculture, it showed the well-cultivated aspect, and the major harvest was various grains. The regulation Swidden in Myungseo-lee started in 1974.

Background: Two major events occurring in the cerebral hemodynamics after successful resuscitation from cardiac arrest are reactive hyperemia and postischemic hypoperfusion. In this study, we examined the effect of Pentoxifylline(PTX) on the rat brain following cardiac arrest. Methods: Fourteen rats were anesthetized and artificially ventilated. Cardiac arrest was produced by chest compression and clamping of tracheal tube for 3 minutes in ketamine anesthetized rats. Circulation was restored by standard cardiopulmonary resuscitation methods. In 7 rats, PTX 10mg/kg was infused at 10min after cardiac arrest(PTX group). In the other 7 rats, same amount of normal saline was infused(control group). Results: In both groups, hemodynamic variables, neurologic deficit(ND) score and histopathologic findings of hippocampal CA1 neurons were observed. Hemodynamic variables and ND score were not significantly different between two groups. Delayed ischemic neurons of hippocampal CA1 were decreased in PTX group(2.2±2.4%) compared with control group(9.1±1.2%). Conclusions: We conclude that PTX prevented development of delayed ischemic neurons in hippocampal CA1 after cardiac arrest. PTX may be useful in emergency situations following cardiac arrest.

Cystadenoma of the minor salivary glands is a rare benign neoplasm. Characteristic histological features of varying sized cystic spaces with intraluminal papillary projections are diagnostic. However, salivary gland tumor is particularly difficult to interpret. Primarily, as further clinical and histological differential diagnoses have to take into account the mucoepidermoid carcinoma and the papillary cystadenocarcinoma. And also, biologic behavior of this peculiar lesion i uncertain. We report on a 71 year old female with a mucosal lesion at the tongue with its histologic features and differential diagnosis. Post-operative course was uneventful and there was no recurrence sign at this time. However, close follow-up is necessary, because the recurrent cases had been reported in literatures.

The purpose of soft tissue defect reconstruction is minimal scar with aesthetic and functional good results. Reconstruction of head and neck, upper extremity, chest, and lower extremity defects has been reported with standard available tissue expansions. Various surgical methods have been used in an attempt to achieve a normallooking skin color, texture, sensation, thickness and same skin adenexa. Therefore, in accordance with defect size and location, the operative method was considered so we select adequate method. Authors achieved good results from 48 cases of tissue expansion, 18 cases of ISLE (intraoperative sustained limited expansion), and 35 cases of presuturing technique. 1)The most common cause of reconstruction for soft tissue defect was post grafted scar 51cases(51%), next was tattoo 20 cases(19.6%), traumatic soft tissue defect 16cases(15.7% ) and nevus 8 cases(7.8%)in order. 2)Males(55.9%)were affected more often than females(44.1%)in the ratio 1, 3 : 1 and the most frequently affected group was the age of 20 to 30 years as 36% . 3)The distribution of incidence and location were as follow : face(39.2%), upper extremity(25.5%), scalp(17.6%), lower extremity(9.8%) and trunk(7.8%). 4)The cause and distribution were scalp in 20 cases(39.2%), face in 40 cases(29.4%) in the post grafted scar, upper extremity 18 cases(90.0%) in the tattoo, upper extremity 4 cases(50.0%), face 2 cases(25.0%) in the nevus and even distribution in the traumatic soft tissue defects. 5)The presuturing technique was best recommended method for soft tissue defect in 4cm diameter lesion on extremity, but ISLE method was used in the open traumatic soft tissue defect. Over 9cm wide scar was resurfaced by expanded skin using tissue expander.
