BACKGROUNDS: Carbon Dioxide (CO2) insufflation during thoracoscopy may result in adverse hemodynamic consequences such as increase in central venous pressure, decrease in cardiac output and increase in arterial carbon dioxide pressure. But the cerebral effects of CO2 insufflation during thoracoscopy are not known yet. To evaluate the cerebral effect of CO2 insufflation during thoracoscopy, jugular bulb venous blood oxygen saturation and pressure were measured. METHODS: Nine patients were underwent thoracic surgery by thoracoscopy and one lung ventilation. After operation, CO2 was insufflated and hemodynamic parameters, arterial blood pressure, heart rate, central venous pressure, jugular bulb pressure, arterial blood gases and jugular bulb venous blood gases were measured at intrathoracic pressure 5 mmHg, 10 mmHg and 15 mmHg respectively. RESULTS: Central venous pressure was increased with insufflation of CO2 of 10 mmHg and 15 mmHg. Jugular bulb pressure was increased with insufflationof of CO2 of 5mmHg, 10 mmHg and 15 mmHg. Arterial PCO2, jugular bulb venous PO2 and jugular bulb venous blood oxygen saturation were increased with insufflation of CO2 of 5 mmHg, 10 mmHg and 15 mmHg. CONCLUSION: CO2 insufflation pressure of 5 mmHg or greater resulted in significant increase in jugular bulb venous blood oxygen saturation and pressure.

Korean Ginseng (Panax C.A. Meyer) has survived empirical efficacy as tonic and geriatric agents for several thousands of years in oriental herbal medicine. But there has been numerous controversial reports about its use in aged hypertensive men due to its allegedly hypertensive effects. Therefore, the author conducted the pharmacological studies of Korean Ginseng extracts on the blood pressure and blood lipid metabolism, during development of hypertension, using SHR(Spontaneously Hypertensive Rat), counterpart model of human essential hypertension. The results obtained were as follows: 1. SHR could be grouped, according to their age, as prehypertensive stage(<6th week after birth), labile hypertensive stage(6th 14th week), early established hypertensive stage(14th-20th week), and late established hypertensive stage(>20th week). 2. Plasma renin activity tended to rise steadily, until established hypertensive stage was reached. Thereafter, plasma renin activity tended to decline. 3. The changes of blood pressure due to Ginseng extract, depended on the amount, route and duration of its administration. Low dose of Ginseng tended to increase blood pressure but high dose of Ginseng tended to decrease blood pressure, until 1 week of intraperitonal administration. But prolonged administration of Ginseng extract beyond 1 week, showed delayed hypertensive effect in the intraperitoneal administration but not in oral administration. 4. SHR seemed to have abnormalities in the lipid metabolism. SHR showed lowered level of serum cholesterol and phospholipid, whereas slightly higher level of triglyceride, and showed lower alpha-lipoprotin fraction but higher pre beta-lipoprotein fraction, as compared with NCR.(=Normal Control Rat). 5. When high fat cholesterol salt diet was fed on, it was possible to indece hyperlidemia and increment of hypertension in SHR. but when high fat cholesterol salt diet and Ginseng extract were fed on concomitantly, Ginseng showed significant inhibiting effect on the development of hyperlidemia and hypertension.

Hemangioma of the ovary is a very rare lesion, although the ovary itself is a highly vascularized organ. In the literature review, about 40 cases were reported all of which were small in size and they were usually identified incidentally. The age range spanned from 4 months to 81 years. Cavernous hemangioma was the most common histologic type. We experienced a case of cavernous hemangioma of the left ovary in a 26 year-old pregnant woman. The lesion was 8x6x2cm in size with well demarcated margin. The cut surface was purple to bluish red in color and had a spongy-like appearance. Microscopically, it was composed of dilated vascular spaces with a common wall.

We immunized sixty two healthy subjects with the five different viral titers (300, 500, 1000, 1500 and 2000 plaque forming unit; pfu) of the MAV/06 strain of live attenuated Varicella-zoster virus (VZV) in order to gain sufficient information on safety and immuogenicity as a vaccine strain. Humoral immunity of all vaccine recipients was tested by the fluorescent antibody to membrane antigen (FAMA) assay and Enzyme-linked immunosorbent assay (ELISA) for the quantitative detection of IgG antibody. We tested neutralized antibody in 62 subjects by plaque reduction neutralization test (PRNT50). All of thirty two subjects with initial seronegative response had antibody by FAMA method at four weeks after immunization with four different preparations of dosage. The geometric mean titers (GMTs) of VZV antibody to membrane antigen was 160.9 in 6 subjects with 1500 pfu group; 83.3 in 14 subjects with 1000 pfu group: 116.2 in 7 subjects with 500 pfu groups and 72.0 in 6 subjects with 300 pfu group. Thirty subjects who had VZV antibody at the time before immunization demonstrated elevated antibody titer by FAMA assay and PRNT50 test. Side reactions of the vaccination was not demonstrated in all cases.

A 53-year-old man had skin-colored linear serpiginous plaque within brownish patch on his left thigh for one year. He habitually drank natural spring water for 3 years. We diagnosed this case as sparganosis infiltrated within dermis by histologic and parasitologic diagnosis. The skin lesion mimicked the cutaneous larva migrans by showing dermal migration of sparganum to pro-duce itchy linear serpiginous plaque. We report an interesting case of sparganosis mimicking cutaneous larva migrans.

Symphyseal injury is increasing in number together with today's speed of development of car industry in Korea. However, this injury is not common in practice. Some authors reported that symphyseal injury is only 4 to 6% of all pelvic fractures. Symphysis pubis has characteristicsl anatomy to maintain mechanical integrity of the pe1vis with circumferential ligament. The pelvis is a ring structure with strong ligaments. This support include the symphysis pubis, the anterior and posterior sacroiliac ligaments, and the strong sacrotuberous ligaments. According to Peltier(1964), when symphysis is separated more than 1.0cm, pubic instability will be developed. However, Wild(1982) reported that pelvic instability develops when separation of the symphysis exceeds more than 2.5cm. Tile(1984) reported that anterior pubic rami acts as a strut to prevent anterior collapse of the pelvic ring during weight bearing. However, in the presence of intact posterior structures, it gives little effect on pelvic stability. In addition to trauma, pelvic instability develops congenitally or by pregnancy. During pregnancy, pregnancy-related hormones relsx the ligameritous stuctures of the pelvic girdle. In most instances, the major pelvic ring returns to normal when the effect of the relaxin hormones disappear. However, in rare instances, a major symphysis disruption may continuously persist. To evaluste the trauma-induced separation of the symphysis pubis, we analyzed the 19 cases with 15 months follow-up on an average, who were treated at the Orthopaedic Department, Kang-Nam St. Marys Hospital, from June 1981 to June 1986. The results were as follows 1. Among 19 cases, 9 cases(47.4%) were male, 10 cases(52.6%) were female. And average age of the patients was 30.2 years. 2. The main cause of the fracture was traffic accident in 18 out of 19 cases. 3. In cases of symphyseal separation more than 3.4cm, fracture-separation of both sacroiliac joint was certainly occured. However, in cases with separation more than 2.2cm, unilalateral fracture-dislocation of sacroiliac joint occurred. 4. Open reduction and interal fixatiopn including external fixation was performed in 9 og cases. As an indication of surgery, separation of the symphysis, which exceeds more than 2.2cm and which associated (1) with sacroiliac fracture-dislocation, (2) failed conservative treatment, and (3) when simultaneously emergency urological operation is indicated.

BACKGROUND: Propafenone is a new class IC antiarrhythmic drug that has been found to be effective in both supraventricular and ventricular tachyarrhythmias. We studied the electrophysiologic and long-term effects of oral propafenone in the patients with paroxysmal supraventricular tachycardia(PSVT). METHODS: The electrophysiologic study was done in 15 patients with PSVT to assess the short-term efficacy of propafenone 450mg daily. For 10 patients with short-term efficacy, follow up study was done to assess the long-term efficacy of propafenone 450mg daily. RESULTS: The electrophysiologic mechanisms of PSVT were AV nodal reentry in 6 patients and AV reentry in 9 patients. During the electrophysiologic study, propafenone prolonged AH, HV and PR intervals significantly(p<0.05), but did not change the corrected SNRT, SACT, and the ERP of atrium, ventricle, AV node and accessory pathway(AP) significantly. The anterograde and retrograde 1:1 conduction capacity of AV node and AP seemed to decrease. Complete block of anterograde conduction over the AP was noted in 2 of 3 patients with manifest WPW syndrome and complete block of retrograde conduction was noted over the AV node in 1 patient with AV nodal reentry and over the AP in 1 patient with AV reentry. Propafenone was effective in 3 of 6 patients with AVNRT and 7 of 9 patients with AVRT. During long term administration for 3 to 11 months in 10 patients with short-term efficacy of propafenone, 7 patients did not report any episode of symptomatic tachycardia and 3 patients reported less frequent palpitation. There were no side effects during short-and long-term follow up except 2 patients with mild indigestion. CONCLUSIONS: Propafenone seems to be a safe, well tolerated and effective drug for short and long-term therapy of patients with PSVT, especially of orthodromic AV reentry.

Upper canine is described as 'cornerstone' of maxilla, and its importance is implicated by long root and good alveolar support, The incidence of impaction of upper canine is the second most frequent next to the third molar because it takes a long period of time to develop, and has a complicated path of eruption, and erupts lately. Generally, the patient who has a palatally impacted canine visit the clinic primarily due to a missing of canine after 12-13 years old. Palatally impacted canine is different from labially impacted canine in its cause and treatment process, It is due to malposition or anomalous lateral incisor rather than arch length deficiency. Once the impaction is identified, the first stage of the treatment is to localize the lesion by radiographic examinations or others and according to severity, orthodontic traction, or transplantation should be considered, and comprehensive diagnosis and treatment plan of malocclusion should be established, Properly managed impacted canine can provide funtion and esthetic through proper diagnosis and treatment of extraction of canine is not indicated.
