This study was performed in order to recognize the identifications of the glycoproteins containing oligosaccharides in human gingiva. After made paraffin sections of human gingiva at 4µm, the sections were incubated with 7 lectins (UEA-I, BS-I, SBA, DBA, WGA, PNA, PNA after neuraminidase treated, Con-A). In order to increase specificity of reactions, the sections were applicated with ABC system. And then the sections were incubated with DAB and were counterstained with hematoxylin. Using the same sections, the sections were done H-E and PAS stains. In WGA, DBA and Con-A, plasma membranes of the layers of all epithelium and connective tissue were stained. In BS-I ; In the epithelium of marginal gingiva, plasma membranes of upper layer of the spinous cell layer and granular cell layer were stained. And in epithelium of sulcular gingiva, plasma membranes of the all spinous cell layer and granular cell layer were stained. In SBA ; Plasma membranes of the granular cell layer were stained. In PNA ; In the epithelium of marginal gingiva, plasma membranes of the basal cell layer and lower layer of spinous cell layer were stained. But lectin reactions were not occurred in thc sulcular gingiva. In PNA treated neuraminidase, plasma membranes of the all epithelial layer except basal cell layer membranes especially cytoplasms of upper layer at the sulcular gingiva and connective tissue were reacted. 1. By the above results, authors could know the identification of oligosaccharides existing g1ycoproteins in the human gingiva. 1) All epithelial layer ; α-D-N-Acetyl-Galactosamine, Sialic acid, D-Glucosamine, α-D-Mannose 2) Basal cell layer ; Galactose-β-(1-3)-N-Acetyl-Galactosamine 3) Spinous cell layer ; α-D-Galactose, Galactose-β-(1-3)-N-Acetyl-Galactosamine 4) Granular cell layer ; α-D-Galactose 5) Connective tissue ; α-D-N-Acetyl-Galactosamine, Siallic acid, β-(1-4)-D-Acetyl-Glucosamine, α-D-Glucosamine, α-D-Mannose 2.

A number of methods have been introduced for support the orbital floor following a maxillectomy without orbital exenteration or severe facial trauma. These methods including skin graft and muscular sling provided the unsatisfactory results, like as diplopia, orbital ptosis, enophthalmos and severe facial deformity. Therefore the bone and soft tissue reconstructions using microvascular free flaps were performed recently by many surgeons, but long time operation, donor site morbidity, postoperative large scar, and ptosis of the flap were pointed out as disadvantages of free flap reconstruction. Vascularized calvarial bone flap, a modified method of free calvarial bone graft, was adequate for reconstruction of the orbital floor and the infraorbital rim as a horizontal buttress, especially in case of poor vascular bed and postradiated state. The authors introduced the vascularized calvarial bone flap for the orbital floor and the infraorbital rim reconstruction in 3 cases of maxillectomy, and could be obtained satisfactory results aesthetically and functionally.

BACKGROUND: Stellate ganglion block (SGB) is known to increase blood flow to the innervations area of the stellate ganglion. Near infrared spectroscopy reflects an increased blood volume and allows continuous, non-invasive, and bedside monitoring of regional cerebral oxygen saturation (rSO2). We investigated the influence of SGB on bilateral cerebral oxygenation using a near infrared spectroscopy. METHODS: SGB was performed on 30 patients with 1% lidocaine 10 ml using a paratracheal technique at the C6 level and confirmed by the presence of Horner's syndrome. The blood pressure (BP), heart rate (HR) and rSO2 were measured before SGB and 5, 10, 15 and 20 minutes after SGB. Tympanic temperature of each ear was measured prior to SGB and 20 minutes after SGB. RESULTS: The increments of the rSO2 on the block side from the baseline were statistically significant at 5, 10, 15 and 20 minutes. The rSO2 on the non-block side compared with the baseline, however, decreased at 15 and 20 minutes. The difference between the block and the non-block sides was significant at 15 and 20 minutes. The BP at 10, 15 and 20 minutes was increased and the HR was increased at 10 and 15 minutes. CONCLUSIONS: We observed an increment of the rSO2 on the block side from the baseline; however, the rSO2 on the non-block side decreased.

We examined the anatomical position of the mental foramina in mandibles foramen normal adult Koreans. 1. The percentages obtained from the study of the relationships between the mental foramen and the lower teeth showed that the most common location was type lv in which the mental foramen lay at the apex of the second promolar. The foramen between thr apices of ice two premolars (type lll) and the foramen between the second premolar and the first molar (type v) occured often and less often rspectively and find no foramen mesial to the first premolar or at the apex of the first premolar and posterior of the first molar (type l, ll, vl). 2. The study of relationship of the mental foramen to the bo of the mandible revealed that mental foramen was situated closer to the lowed border of the mandibular body. The distance ratio between the mental foramen and the alveolar crest to that between the mental foramen and the lower border was approximately 1.2 : 1. The height of the mandibular body was 31.09±2.80mm on the left side and 30.97±2.48mm on the right. 3. The distance from the mandibular symphysis to the anterior border of the mental foramen measured 29.52±2.01mm on the left, 30.82±2.04mm on the right side, and from the mandibular symphysis to the posterior border of the mandibular ramus was 104.20±4.74mm on the left, 105.44±4.49mm on the right side. It indicates that the mental foramen lies approximately at one-fourth of the distance from the mandibular symphysis to 2017-04-19 the posterior border of the ramus. 4. The distance from the superior border of the mental foramen to the bottom of the lower second premolar socket was found to be positive. It was 5.46±3.09mm on the left, 5.73±3.03mm on the right side. This indicates that the bottom of the lower second premolar socket is slightly higher than the superior border of the mental foramen.

Tietze's syndrome is an inflammatory condition associated with painful swelling of the costochondral, costosternal, and sternoclavicular joints. Tietze's syndrome has been mostly attributed to microtrauma until now; however, this etiology is currently disputed. The diagnosis is based on clinical findings, although a few studies suggest the advantages of imaging. We report a case of Tietze's syndrome with a review of radiological findings, especially magnetic resonance imaging (MRI) with dynamic contrast enhancement.

Postlumbar puncture headache is a common complication of spinal anesthesia. It usually may be alleviated by adequate hydration, continuous recumbency, abdominal compression and analgesic medication. However, these conservative treatments are only symptomatic and epidural blood patch is curable approach based on pathophysiology. During the 3 year period from 1988 to 1990, 700 cases of spinal anesthesia were recorded by Wonju Christian Hospital, Wonju Medical College, Yonsei University. This study was primarily undertaken to observe several aspects of postspinal headache i.e. incidence, age and sex distribution, onset, duration and treatment. The results were as follows: 1) The overall incidence of headache was 10.6% (74 cases). 2) Headache occurred in highest frequency in patients in the third and fourth decades. 3) Frequency of headache was higher in women. 4) The onset of headache was within postop. 3 days. 5) The duration of headache was within 6 days. 6) a) 12 cases were cured spontaneously. b) 52 cases were cured by conservative treatment. c) 10 cases were cured by the epidural blood patch.

BACKGROUND: Single or multiple episodes of brief period of ischemia and reperfusion(ischemic preconditioning, IP) have been shown to limit infarct size after a subsequent longer period of ischemia. A considerable number of possible mechanisms has been proposed, however, controversies still remain. Accordingly, we evaluated the effect of four cycles of 5 minutes ischemia and 5 minutes reperfusion(IP) followed by subsequent 30 minutes ischemia(ISCH) and 60 minutes reperfusion using isolated Langendorff-Perfused rabbit hearts. Methods and RESULTS: After a 50-minute recovery phase, parameters of the left ventricular function(LVF) including left ventricular developed pressure(LVDP), contractility and the heart rate were recorded, and ultrastructure was examined. Myosin ATPase activity was determined by measurement of inorganic phosphorus and isozymes of the myosin heavy chain were examined by polyacrylamide gel electrophoresis containing pyrophosphate buffer. The ISCH hearts showed severe to irreversible change of the cardiac myocytes homogenously in contrast to the IP hearts in which changes were not homogenous and irreversible injury was only focal. However, parameters of the LVF were not significantly different between the IP and the ISHC hearts during reperfusion. Myosin ATPase activities were also not significantly different(0.67+/-0.123 micromol/mg protein/h in the IP hearts, 0.56+/-0.172 micromol/mg protein/h in the ISCH hearts, and 0.76+/-0.239 micromol/mg protein/h in the control hearts). Band patterns of the myofibrillar proteins, separated by sodium ddodecyl sulfate-polyacrylamide gel electrophoresis, revealed no differences between the IP, ISCH and the control hearts. Myosin heavy chains in the IP and the ISCH hearts were separated into 3 isozymes, V1,V2and V3in pyrophosphate gel electrophoresis in contrast that the control hearts revealed two isozymes, V1and V2. However, there were no differences in the protein composition and electrophoretic motility between the IP and the ISCH hearts. CONCLUSION: These results indicate that IP could not attenuate the changes in LVF, myosin ATPase activity and myosin isozymes on reperfusion, however, it could attenuate the ultrastructural changes of the cardiac myocytes.
