In fully edentulous cases, which are accompanied by severe residual ridge resorption and impairment of supporting tissues of complete dentures, proper diagnosis and systemic treatment planning are required for the improvement in retention, stability, and support of prosthesis. Provisional restoration, while it is unfamiliar in complete denture restoration, can be used as a valuable tool, which makes possible to evaluate the stability of complete dentures and receive feedback from patients in complex clinical situations. In this case, a provisional denture was used to improve stability of impression, polished, and occlusal surfaces of complete denture, and to consider esthetic requirements before final denture construction. The result was clinically satisfactory in terms of functional and esthetical aspects.

Reflex gasping when hanging leads to passive and vigorous vomiting, the mechanical force of which causes gastric mucosa laceration. Mallory-Weiss syndrome is a tear in the gastro-esophageal junction or its adjacent mucosa, and this can occur due to nausea or vomiting that is caused by various etiologic factors. Gastric fundus is the most common site of gastric mucosa lacerations. We report a case of a 41-year-old man, who tried to hang himself and, as a result, caused multiple gastric mucosa lacerations that were treated by an endoscopic hemostatic procedure in the emergency room.

Hyperhomocysteinemia is an independent risk factor for cardiovascular, cerebrovascular and peripheral vascular diseases that are complicated by atherosclerosis and a thromboembolism. An increased level of plasma homocysteine develops from a genetic defect in the of enzyme for the homocysteine metabolism or a vitamin deficiency. Hyperhomocysteinemia has direct toxic effect on the vascular endothelium and causes damages to the antithrombotic action of vascular endothelial cells. Most cases of hyperhomocysteinemia are asymptomatic, but cardiopulmonary or cerebrovascular incidents developin rare cases. In the case of a thromboembolism with an unknown cause, hyperhomocysteinemia should be considered in a differential diagnosis. The authors report a case of pulmonary thromboembolism in a patient with hyperhomocysteinemia with a review of the relevant literature.

PURPOSE: The purpose of this study is to find the effect of rare earth magnet's magnetic field of to the osteoblast around the implant by the means of observation number, and distribution around the implant which is connected to the permanent magnet but not, counted and compared by the number of cells attached to the surface of the implant. MATERIAL AND METHOD: The permanent magnets, made in the healing cap form, were connected to the implant fixture, and placed on the culture plate, The osteoblast-like cell: MC3T3-E1 were used for cell culture. As the control group, the implant were connected to normal healing cap, and cultured in the same conditions. 48 hours later, using inverted microscope, the number and distribution of osteoblast around the implant were observed, and 72 hours later, the number of the cells attached to the implant were counted. RESULTS: As a result, the implant connected to the permanent magnet had proved to have a more concentrated cell distribution rate than the control group. The implant connected to the permanent magnet, neck area: which has about 10 gauss magnetic force, had more cells than apex area. The implant connected to the permanent magnet had proven to attach to the osteoblast more productively than control group's implant. CONCLUSIONS: This research showed that the magnetic field of the permanent magnet affected the distribution and growth rate of the osteoblast around the implant. In order to support this study, it also had need to monitor the progress of the permanent magnet specifically shown on the neck area, which has10 gauss magnetic force. So after additional research on the distribution and attachment of the cells, and further more, on bone formation, it will be concluded that the clinical applications, such as immediate loading of implant treatment are possible.

Adenoid cystic carcinoma (ACC) is a rare variant of adenocarcinoma that usually occurs in the major salivary gland. In breast, adenoid cystic carcinoma is a very rare carcinoma accounting for less than 1% of the all breast carcinoma. It has an excellent prognosis with the lower incidence of distant metastasis and axillary lymph node involvement, and a benign looking or low suspicious findings on imaging. We will report the radiologic and pathologic finding of the adenoid cystic carcinoma that is incidentally detected in the right breast of asymptomatic 47-year-old woman, who had taken annual screening mammogram and ultrasonogram.

BACKGROUND: The use of furosemide is well recognized as a predisposing factor to nephrocalcinosis (NC) in infants. Although furosemide is widely used for various clinical settings in adults, the association of furosemide use and nephrocalcinosis in adults is not well established. METHODS: We studied 18 consecutive adult patients(male : female=1 : 17, age range 21-59 years) who took furosemide habitually to control their weights or edema for a long-term period(range 3-25 years). NC was evaluated using renal ultrasonography(US), computed tomography(CT) and/or kidney biopsies. Patients were categorized into NC(+) and NC(-) groups while the difference in clinical features were investigated. RESULTS: Renal US and CT revealed nephrocalcinosis in the bilateral medullary pyramids in 15(83.3 %) out of 18 patients. The duration of furosemide abuse was not different between NC(+) and NC(-) groups(10.1+/-1.7 years vs. 15.3+/-0.9, p>0.05). The daily dose of furosemide was higher in NC(+) group than the NC(-) group(538+/-174 vs. 67+/-13 mg/day, p<0.01), however. All patients showed a variable degree of renal insufficiency and there was no difference in creatinine clearance between two groups(p>0.05). The kidney biopsies performed in three patients showed focal tubulointerstitial fibrosis and atrophy and calcifications were observed at outer medullary tubulointerstitium. CONCLUSION: Long-term furosemide abuse could cause medullary nephrocalcinosis in adults and the risk of developing of nephrocalcinosis is correlated with the daily dose of furosemide. We suggest that long-term furosemide abuse should be suspected in adult patients when medullary nephrocalcinosis is incidentally detected by US and/or CT.

The majority of undiagnosed diaphragmatic ruptures are associated with a high mortality rate if not treated immediately. A high index of suspicion for diaphragmatic injury during initial evaluation is the most important factor. A case was experienced involving delayed presentation of a traumatic diaphragmatic hernia, in a 49 year old female injured in a road traffic accident a year prior to admission. She was admitted with complaints of left side chest pain, nausea, and vomiting for 7 days. She was diagnosed as a diaphragmatic hernia on her left side by several diagnostic tests including a gastroscopy and CT scan. Her medical history was carefully examined as well. Surgical repair was performed.

Adherence of Candida albicans(C. albicans) to the surface of a denture is believed to be an initial and essential step in the formation of denture-induced stomatitis. Previous studies have provided enormous infomation on the relationship between composition of palatine gland/parotid saliva and upper denture stomatitis. Relatively little information is available on the correlation between lower denture stomatitis and sublingual-submandibular(SLSM) saliva. The plaque samples were collected from the two sites(100mm2) on the inner surface of lower partial denture corresponding to the stomatitis and healthy region of the lower partial dentures of 12 denture stomatitis patients and 6 normal persons who wore lower partial dentures. The samples were plated to isolate C. albicans on a selective Saboraud's dextrose agar plate and the isolates were identified by germ tube test and gram staining. The subjects were divided into group I (stomatitis with C. albican), group II (lesion without C. albicans), group III (no lesion but C. albicans), and group IV (normal and healthy denture wearer). Individual SLSM saliva (20microgram of protein) was analyzed by SDS-PAGE(SDS-poly-acrylamide gel electrophoresis) with Coomassie brilliant blue and PAS(Periodic Acid Schiff) staining. The salivary proteins separated in the polyacryamide gels were subjected to immunoblot analysis using anti-lactoferrin, anti-sIgA, and anti-secretory component of sIgA. In this study using custom made acrylic denture resin beads(5mm in diameter) coated with stimulated individual SLSM saliva, the binding ability of individual C. albicans strains to the beads was observed. Levels of C. albicans adhered to the acrylic resin beads were determined by measuring the optical density of the bound C. albicans to the beads at 580nm. The results showed that a higher number of C. albicans was observed in the lesion site than health site. The saliva of group I contained more high molecular weight glycoprotein(mucin, MG1) as compared to group II, III, and IV. And lactoferrin and sIgA affected to the binding ability of C. albicans to acylic resin beads. Binding ability of individual C. albicans to the acrylic resin coated with respective individual saliva was found to be greater in group I than the other 3 groups. And when bound cells of C. albicans isolated from individual subject #2 to the saliva coated beads were used, binding ability of subject #2 saliva coated beads was founed to be greater than the other subjects. These results suggested that denture induced stomatitis is related to individual patient's salivary protein composition, especially MG-1. Future studies will be directed toward saliva examination of patients who have general disease and analysis of pellicles formed on prosthesis with respect to oral disease.

BACKGROUND: The nucleus tractus solitarius (NTS), the region of the brain stem in which primary baroreceptor afferents teminate, is critically important in the normal regulation of arterial pressure (AP). In the NTS, excitatory amino acids such as L-glutamate serve as the main neurotransmitter in the regulation of AP. However, the function of GABA in the NTS has not been established. To test the function of GABA, we applied GABAergic agents to the NTS. METHODS: The experiments were conducted on adult male Sprague-Dawley rats weighing 300-500g. A cannula (PE-50 tubing filled with heparinized saline) was inserted into the femoral artery for recording of AP and heart rate(HR). Another cannula was inserted into the femoral vein for administration of nitroprusside or phenylephrine. After rats were placed on a sterotaxic instrument, the dorsal surface of the medulla was exposed, and with the aid of a surgical microscope, the NTS was visualized. Drug injections were made into the NTS using single- or three-barreled grass micropipettes pulled to an outer diameter of 80-100(micro)m and connected to a 1(micro)l Hamilton syringe. RESULTS: The follwing results were obtained in this experiment. Injection into the NTS of 10 or 20 nmol nipecitic acid, a selective inhibitor of GABA untake, produced an increase in AP. The pressor responses evoked by two doses of nipecotic acid were not significantly different. Injection of GABA(A) agonist, musciml(5 pmol in 80 nl artificial CSF) and GABA(B) agonist, baclofen (20 pmol in 80 nl) into the NTS of urethane-anesthetized rats prodused an increase in AP of 16.6+/-1.3 and 27.6+/-1.5 mmHg, respectively. Thus the pressor response to GABA(B) agonist was greater than to GABA(A) agonist. On the other hand, microinjection of GABA(A) antagonist, bicuculline and GABA(B) antagonist, phaclofen into the NTS decreased AP by approximately 13.4+/-1.0 and 20.9+/- mmHg, respectively. Thus injection of nipecotic acid into the NTS was greater in control group compared with the muscimiol or baclofen groups. The AP changes caused by i.v. injection of nitroprusside or phenylephrine were smallest in control group and greatest in the baclofen group. When calculated as baroreflex sensitivity, the change was greatest in control group and smallest in the baclofen group. CONCLUSION: From these results it was concluded that GABA in the NTS plays an important role in the regulation of AP, especially through GABA(B) receptors, and have an inhibitory effect on baroreceptor reflex.
