The effects of unilateral hypoxic ventilation on pulmonary hemodynamics, alveolar-arterial oxygen tension difference (A-aDO2) and intrapulmonary shunt in 10 dogs were studied under unilateral hypoxic ventilation using nitrogen. Hear rate, mean arterial pressure, central venous pressure, mean pulmonary arterial pressure, pulmonary capillary wedge pressure, cardiac output, blood gases and hemoglobin were measured during controlled ventilation with 100% oxygen and unilateral hypoxic ventilation. Using the above steps pulmonary hemodynamics, (A-a)DO2 and intrapulmonary shunt were calculated and the following results were obtained. 1) Mean pulmonry arterial pressure significantly increased (20%) from 20.6+/-2.60mmHg to 24.8+/-2.46mmHg(p<0.005) and pulmonary vascular resistance also significantly increased(43%) from 434+/-68.4 dynee. sec/cm(2) to 605+/-81.0 dynes. sec/cm(2)(p<0.005), whereas the cardiac output decreased (8%) from 1.92+/-0.23 l/min to 1.76+/-0.21 l/min(p<0.05) after unilateral hypoxic ventilation. 2) Alveolar-arterial oxygen tension difference significantly increased from 180+/-23.2mmHg to 470+/-31.9mmHg(p<0.005) after unilateral hypoxic ventilation. 3) Intrapulmonary shunt significantly increased from 9.5+/-1.40% to 24.8+/-2.02%(p<0.005) after unilateral hypoxic ventilation, but it was much lower than the mathematically expected value(40% over). The above findings suggest the operation of a protective mechanism, which causes hypoxic pulmonary vasoconstriction in the unilateral hypoxic lung, and diverts blood flow from the hypoxic to the non-hypoxic lung and so minimizes the hypoxic effect on the arterial blood.

It has been reported that pupillary paralysis is rare findings in typical Guillain-Barre syndrome(GBS). We experienced a 56-year-old male with fulminant GBS who pupillary paralysis. He showed quadriplegia, total paresis of motor cranial nerves including bilateral ptosis and complete opthalmoplegia. Pupils were dilated up to 8mm and fixed. After a one year follow up, his pupil slowly constricted to light. The instillation of 0.1% pilocarpin caused both pupillary constriction. These results pointed to postganglionic involvement of pupillary parasympathetic nerves.

PURPOSE: We investigated the direct labeling method of antibody with 99mTc and 188Re and examined the stability and function of these labeled compounds in in vitro and in vivo. MATERIALS AND METHODS: Disulfide bond of nonspecific human IgG was reduced to -SH group by 2-mercaptoethanol. Stannous ion was used to reduce 99mTc and 188Re. The stability of 99mTc-IgG and 188Re-IgG was estimated upto 24 hrs. Biodistribution was evaluated in abscess bearing rats at 4 and 24 hr post-injection of 99mTc or 188Re labeled IgG. RESULTS: The number of -SH group per reduced IgG molecule was 2.34. The labeling yield of 99mTc-IgG and 188Re-IgG were 90% and 95%, respectively. The stability of 99mTc-IgG at 1, 4, 6 and 24 hr was 91%, 83%, 78%, 7% and that of 188Re-IgG, high uptake was found on kidney, blood, stomach and abscess (9.42+/-0.68, 1.43+/-0.24, 0.86+/-0.18, 0.72+/-0.10 %ID/g, respectively). The uptakes at 24 hr were kidney, abscess, stomach, and blood in descending order. In case of 188Re-IgG, high uptake at 4 hr post injection appeared on kidney, blood, abscess and stomach (3.92+/-0.62, 1.32+/-0.08, 0.88+/-0.01, 0.26+/-0.06, respectively). The upatkes at 24 hr were kidney, abscess, blood abd stomach in descending order. The abscess to blood uptake ratio of 99mTc-IgG was 0.5 at 4 hr and 2.02 at 24 hr and that of 188Re-IgG was 0.67 and 1.29. CONCLUSION: 99mTc-IgG and 188Re-IgG and 188Re-IgG canbe labeled efficiently with direct labeling method. However, 99mTc-IgG and 188Re-IgG, labeled with direct method, was unstable. Further study in needed to enhance the stability of the antibody labeling.

OBJECTIVE: In patients with spontaneous intracerebral hemorrhage (ICH), the risk factors for seizure and the effect of prophylactic anticonvulsants are not well known. This study aimed to determine the risk factor for seizures and the role for prophylactic anticonvulsants after spontaneous ICH. METHODS: Between 2005 and 2010, 263 consecutive patients with spontaneous ICH were retrospectively assessed with a mean follow-up of 19.5 months using medical records, updated clinical information and, when necessary, direct patient contact. The seizures were classified as early (within 1 week of ICH) or late (more than 1 week after ICH). The outcomes were measured with the Glasgow Outcome Scale at discharge and the modified Rankin Scale (mRS) at both 2 weeks and discharge. RESULTS: Twenty-two patients (8.4%; 9 patients with early seizures and 13 patients with late seizures) developed seizures after spontaneous ICH. Out of 263 patients, prophylactic anticonvulsants were administered in 216 patients. The prophylactic anticonvulsants were not associated with a reduced risk of early (p=0.094) or late seizures (p=0.326). Instead, the factors associated with early seizure were cortical involvement (p<0.001) and younger age (60 years or less) (p=0.046). The risk of late seizure was increased by cortical involvement (p<0.001) and communicating hydrocephalus (p=0.004). The prophylactic anticonvulsants were associated with a worse mRS at 2 weeks (p=0.024) and at last follow-up (p=0.034). CONCLUSION: Cortical involvement may be a factor for provoked seizures. Although the incidence of early seizures tended to decrease in patients prescribed prophylactic anticonvulsants, no statistical difference was found.

Primary coronary stenting is one of the established therapeutic options for acute myocardial infarction. The risk of balloon rupture during stenting may be increased after high pressure inflation technique was introduced. Balloon rupture during stenting may cause catastrophic complications such as extensive dissection, acute closure, coronary perforation. We report a case of balloon rupture during primary stenting in acute myocardial infarction, which caused acute thrombotic closure of target and remote coronary arteries simultaneously.

Proper ligament balancing, restoration of the mechanical axis and component alignment are essential for the success and longevity of a prosthesis. In conventional total knee arthroplasty (TKA), an intramedullary guide is used to improve the alignment. An extramedullary guide can be used in cases of severe femoral bowing or intramedullary nailing but its use is more subjective and relies on the surgeon's experience. This paper reports two successful cases of navigation-assisted TKA for severe right knee osteoarthritis retaining a femoral intrameullary nail, and left knee osteoarthritis retaining a distal femoral plate.

It was Observed required doses of morphine and pancuronium bromide or d-tubocurarine in 34 cases of open heart anesthesia which performed between October 1, 1974 and August 31, 1975 is SNUH with the induction of sleeping dosea of 2.5% thiopental and succinyIcholine for intubation, and maintenance of 50% of nitrous oxide and oxygen. It was obtained the results as followings: 1. The average required dose of morphine in open heart anesthesia was 0.34+/-0.25 mg/kg body weight (34 cases). 2. The average required dose of pancuronium bromide in open heart anesthesia was 0.212+/-0.091mg/kg body weight (28 cases). 3. The average required dose of d-tubocurarine in open heart anesthesia was 0.745+/-0.298 mg /kg body weight (8 cases); 4. The duration of open heart anesthesis and extracorporeal circulation were 396 minutes and 102.8 minutes respectively. 5.
