Cervical plexus block has been evaluated clinically for surgery of the anterior neck in 13 patients during the 10 months(from July 1981 to April 1982) at the Department of Anesthesiology in Capital Armed Forces General Hospital. We have assessed CPB for technique, onset, anesthetized area, duration, complication and supplimentary agents, and reviewed the anatomical aspects of cervical plexus. The distribution of injected local anesthetics was demonstrated under radiography using Urographin. We experienced incomplete block in 9 cases which needed substitution with Thalamonal. The incidence of complications was few and most significant complication seen in this study was respiratory difficulty. However, There was no evidence for phrenic nerve paralysis. Cervical plexus block was performed safely and effectively for surgery of the anterior neck.

Though exercise T1-201 myocardial perfusion-scintigraphy is an important test in the diagnosis and evaluation of coronary artery disease, this test is limited in cases with poor physical conditions and unstable angina and the physical characteristics of thallium are not ideal for nuclear imaging of the myocardium. Recently, technetium-99m-labelled agent(99mTc-MIBI) has been developed to improved the quality of imaging and for easy usage in myocardial perfusion scan. Therefore, we performed dipyridamole 99mTc-MIBI myocardial scintigraphy and coronary angiography on 25 subjects who were suspeced to have coronary artery disease and the results obtanined were as follows ; 1) The overall diagnostic sensitivity of dipyridamole 99mTc-MIBI perfusion scintigraphy was 73.4%, while specificity was 66.7%. 2) Per vessel sensitivity for coronary artery disease diagnosis by the test was 71.4% and a per vessel specificity for coronary artery disease was 95.7%. 3) In all 75 coronary arteries, LAD had a sensitivity of 66.7%(10/15) and a specificity of 100%(10/10); RCA had a sensitivity of 75%(6/8) and a specificity of 82.4%(14/17); LCX had a sensitivity of 60%(3/5) and a specificity of 100%(20/20). 4) After infusion of dipyridamole, the most frequent adverse effect was chest pain which was seen in 8 cases(32%). The headache was seen in 7 cases(28%). Most of the symptoms were mild in severity and subsided spontaneously but 3 subjects were severe enough to require intravenous administration of aminophylline. In conclusion, dipyridamole 99m2011-06-17Tc-MIBI myocardial perfusion scintigraphy is a useful and safe test for diagnosis of coronary artery disease.

PURPOSE: It is well recognized that apoptosis is important in embryonic development, homeostatic control of normal tissues, carcinogenesis, tumor development and cancer therapy. Several papers have been reported the phenomenon of radiation-induced apoptosis and suggested its potential relevance to cancer radiotherapy. It has been shown that apoptosis is regulated by various cytokines. But the relationship between radiation induced apoptosis and cytokines have not fully understood in detail, yet. MATERIALS AND METHODS: In this study, we performed to determine the role of cytokine in the radiation -induced apoptosis of rat's small intestine. The rats were divided into 6 groups according to the sacrifice day (1, 2, 3, 5, 7, 14 days) after whole body irradiation with single dose of 8 Gy. RESULTS: Radiation induced intestinal damage was noted from first day of radiation and the most active regeneration was seen in the groups of 5 days after radiation. Abundant apoptosis were observed in damaged crypts of small intestine 1 day after radiation. Afterwards, the number of apoptosis was gradually diminished, but the second peak of apoptosis was noted in 5 days after radiation. On immunohistochemical study, IL-1, and TNF were expressed 1 day after radiation, but not expressed after that. IL-6 was expressed with strong positivity in 1, 3 days after radiation. CONCLUSION: A apoptosis seems to be the important mechanism of radiation induced small intestinal damage, and is possibly induced by the release of cytokines, such as IL-1, IL-6, TNF, in view the simultaneously increased appearance of apoptosis and cytokines. The second peak of increased apoptosis is thought to be related to remodeling of active regenerative activity, and it is not associated with cytokine expression.

This study was conducted to investigate physiological characteristics of Trichoderma spp. isolated from Pleurotus spp. Damage tests of Pleurotus spp. and mycotoxins tests of Trichoderma spp. were also done. The optimal growth temperature of Trichoderma spp. was 27~30degrees C. Although, T. longibrachiatum was able to grow at 37degrees C and grew 30~40 times faster than Pleurotus. The colony colour on PDA medium of T. cf. virens was yellowish green, T. longibrachiatum was yellow, and T. harzianum was turning to bright green. In damage tests of Pleurotus by Trichoderma, T. cf. virens caused the most severe damage to Pleurotus. T. longibrachiatum and T. harzianum caused less damage on Pleurotus but were able to cause greater damage to P. eryngii. One of the mushroom cultivars, P. ostreatus 8 was the most resistant to all Trichoderma spp.. Chitinolytic mycotoxin released by Trichoderma spp. caused 52.7% damage to Pleurotus. Mycotoxins released by T. longibrachiatum caused the greatest damaged (78.6%) on P. eryngii.

PURPOSE: Chronic tophaceous gout is a painful and disabling inflammatory disease. Surgical treatment for chronic tophaceous gout is very difficult with many complications. This study evaluated the efficacy of shortening scarf osteotomy on the treatment of chronic tophaceous gout in the 1st metatarso-phalangeal (MTP) joint. MATERIALS AND METHODS: From January 2006 to December 2015, 14 patients (19 cases) who underwent axial shortening scarf osteotomy for chronic tophaceous gout were reviewed. All patients were male. The average age at the time of surgery was 59.6 years (42~66 years). The minimum follow-up was 24 months. Total removal of the tophi mass with the adhered medial capsule of the 1st MTP joint was attempted. Axial shortening scarf osteotomy was done on the 1st metatarsal shaft. The visual analogue scale (VAS) for pain and the American Orthopaedic Foot and Ankle Society (AOFAS) forefoot score was assessed preoperatively and postoperatively. The range of motion (ROM) of the 1st MTP joint was also compared pre- and postoperatively. RESULTS: The average size of the extracted tophaceous mass was 32 mm. The mean amount of the length of metatarsal shortening was 4.9 mm. The mean ROM of the 1st MTP joint was improved from 30.4° to 62.3°. The mean AOFAS forefoot score improved from 51.4 to 86.6 points. The mean VAS for pain improved from 4.6 to 0.3 points. CONCLUSION: The axial shortening scarf osteotomy used on chronic tophaceous gout could reconstruct the 1st MTP joint with an improved ROM and was free of pain. Axial shortening scarf osteotomy is suggested as a useful and effective method for the treatment of chronic tophaceous gout.

BACKGROUND: We aimed to examine the factors that influence synovialization of the grafted tendon after double-bundle anterior cruciate ligament (ACL) reconstruction based on second-look arthroscopic findings. METHODS: Out of 205 knees that were treated between August 2008 and May 2016 with double-bundle ACL reconstruction using bio-absorbable cross-pins and Endobuttons for femoral tunnel fixation, we enrolled 65 knees (64 patients) that underwent second-look arthroscopy with hardware removal at 1 year postoperatively. Measured clinical outcomes included the Lysholm score and Tegner activity score that were evaluated preoperatively and during the final follow-up. We analyzed the relationship between synovial coverage and patient age, length of the preserved remnant tissue on the tibial side, type of bundle (anteromedial or posterolateral), type of graft (autograft or allograft), and time from injury to surgery. RESULTS: The area of synovial coverage showed a significant statistical correlation with patient age and the length of the preserved remnant tissue on the tibial side. The average synovial coverage was significantly better for the anteromedial bundle than for the posterolateral bundle, better for the autograft than for the allograft reconstruction, and better when treated in the acute stage than in the chronic stage. However, synovialization of grafted tendon did not correlate to clinical outcomes. CONCLUSIONS: While we were able to identify several factors influencing synovialization of the grafted tendon after double-bundle ACL reconstruction, including patient age, length of preserved remnant tissue of the torn ACL, type of bundle, type of graft, and time from injury to surgery, we found no evidence that increased synovialization improves clinical outcomes at 1 year postoperatively.

BACKGROUND: The substantia nigra pars reticulata is a critical site for the control of epileptic seizures. The potentiation of the inhibitory gamma-amino butyric acid (GABA) ergic input from the striatum to the substantia nigra pars reticulata suppresses primary or secondary generalized seizures in rats. Recent data suggests that the projection from the subthala-mus to the substantia nigra pars reticulata plays a critical role in the control of some forms of epileptic seizures. METHODS: We examined the possible involvement of the excitatory glutamatergic input from the subthalamic nucleus (STN) to the substantia nigra in pilocarpine-induced seizures by the direct injection of GABA receptor agonist (muscimol) and n-methyl- D-aspartate (NMDA) receptor antagonist (MK-801) into the substantia nigra pars reticularis (SNr) and the subthalamic nucleus respectively. Sprague-Dawley rats were classified into four groups depending on the pretreatment; the injection of saline (STN sham) or muscimol (STN) into the subthalamic nucleus, and the injection of saline (SNr sham) or MK-801 (SNr) into the substantia nigra. Seizure was induced by the intraperitoneal injection of pilocarpine (400 mg/kg). RESULTS: Mean seizure stages in the STN group (1.5 +/-0.5) and SNr group (1.3 +/-0.5) were significantly lower than STN sham group (4.8 +/-0.4) and SNr sham group (4.8 +/-0.4) (P <0.05). Electroencephlograms showed typical status epilepticus patterns in the sham operation group but only discrete ictal discharges with slowing and intermittent ictal spikes were shown in both STN and SNr group. Viable cell numbers in the CA1 and CA3 in STN and SNr groups were significantly higher than those of the sham group (P <0.05). CONCLUSIONS: These results provide evidence for the role of subthalamo-nigral projections in the modulation of pilocarpine-induced seizures.

Two cases of tension pneumocephalus follwing surgery are reported. Tension pneumocephalus appears to be another potential complication of the operation and should be considered whenever a patient fail to recover as expected following surgery. Peaking of frontal lobe, mountain appearance of frontal lobe, and air densities at the cisterns are characteristic findings of tension pneumocephalus. Its diagnosis and treatment are easy and simple.
