The parathyroid cyst is a relatively uncommon disease and usually identified during the operation for a presumed thyroid mass. Thirteen cases of parathyroid cyst (2 males, 11 females) treated from 1981 to 1993 were reviewed. Ages ranged from 17 to 59 years(mean, 41 years). Gross measurement of the tumor size varied from 1.0 to 10.0 cm in diameter with a mean of 4.8cm. All of the 13 patients presented with a chief complaint of painless anterior cervical mass. Only one complained of mild symptom of dyspnea and voice change due to huge cyst in paratracheal space. No functional cyst was identified. Diagnostic studies included ^99mTc thyroid scan (n=11), ultrasonography (n=10), computerized tomography (n=4) and fine needle aspiration(FNA) (preoperative, n=4; intraoperative, n=3). All diagnostic precedures but needle aspiration were nonspecific. Cysts were found in right inferior parathyroid(n=4), left inferior parathyroid (n=7), or anterior superior mediastinum (n=2). The FNA of the cyst contents revealed watery clear fluid with elevated parathyroid hormone level and was diagnostic in each cases. Four patients were treated initially with needle aspiration, of which only one patient was successful, and 3 patients who were unsuccessful to needle aspiration and the remaining 9 were effectively treated with surgical extirpation. Our experience suggested that needle aspiration may be of significant help in diagnosis and treatment of parathyroid cyst, but most of the patient could be treated successfully by surgical extirpation with an excellent chance for curability.

OBJECTIVE: The purpose of this study was to reveal the position of the incisive foramen in relation to the incisive papilla and cusp tips. METHODS: Plaster models and CT images of 25 adult orthodontic patients were used to measure the width of the incisive canal and positions of the anterior and posterior borders of the incisive foramen in relation to the incisive papilla. RESULTS: The palatal surface distance from the interdental papilla between the maxillary central incisors to the posterior border of the incisive foramen along the palatal surface was 1.7 fold of the distance from the interdental papilla between the central incisors to the posterior border of the incisive papilla. The distance between the posterior border of the incisive papilla and posterior border of the incisive foramen along the palatal surface was 6.15 +/- 1.75 mm. The anteroposterior position of the posterior border of the incisive foramen was slightly anterior to the lingual cusp tips of the maxillary 1st premolars. The width of the incisive foramen was 4.03 +/- 0.64 mm, therefore it is recommended to position the mini-implant more than 3 mm laterally when placing a mini-implant lateral to the incisive foramen, from the center. CONCLUSIONS: These results can be used as a reference in presuming the position of the incisive foramen when placing mini-implant in the anterior palate area.

PURPOSE: CD24 is a small heavily glycosylated glycosylphosphatidylinositol-linked cell surface protein, which is expressed in hematological malignancies as well as a large variety of solid tumors. The authors aimed to evaluate the CD24 protein expression in fibroadenomas and adenocarcinomas of the breast and its correlation to clinicopathological data. METHODS: Immunohistochemical staining for CD24 was performed on 28 mammary neoplasia, diagnosed as either adenocarcinomas (22 cases) or fibroadenomas (6 cases), to examine the relationship with clinicopathological parameters. The results of the immunohistochemical staining were evaluated by the stainability (negative, weak-, moderate-, strong-positive) and staining patterns (membranous vs. intracytoplasmic) for statistical analyses. RESULTS: The present study clearly demonstrates that CD24 was abundantly expressed in adenocarcinoma, compared to in fibroadenomas of the breast (P<0.001). Intracytoplasmic staining was noted in the adenocarcinomas only but this was not statistically significant between the adenocarcinoma and fibroadenoma groups. No significant correlations of the CD24 stainability or staining pattern were detected with the nodal status, tumor histological grade or histological subtypes. CONCLUSION: Our data suggest that abundant membranous expression or intracytoplasmic expression of CD24, as detected by immunohistochemistry, is an important tissue marker for a mammary epithelial neoplasm, which could help to define adenocarcinomas from fibroadenomas.

BACKGROUND: Recent studies revealed that inhalational anesthetics (IA) attenuate NO production. But the hemodynamic changes produced by IA in septic syndrome patient are still sufficient to threaten patient, surgeon and anesthesiologist. So we examined which IA is proper to maintain vascular contractile force and evaluated the effects of NOS inhibitors on contractile force of septic rat aorta under IA. METHODS: Aortic ring preparation was obtained from LPS-treated (1.5 mg/kg, i.p. for 18h) rats. The development of sepsis was confirmed by iNOS activity and iNOS expression using RT-PCR. Contractile responses of aorta to phenylephrine admministation in the presence or absence of halothane, enflurane and isoflurane were evaluated. We also evaluated the effects of NOS inhibitors, one is NG-nitro-L-arginine methyl ester (L-NAME) and the other is aminoguanidine. Statistical significances (p<0.05) were analyzed according to data characteristics by unpaired t-test and paired t-test. RESULTS: The contractile responses to phenylephrine admministration were attenuated in LPS-treated rings. Isoflurane, even at the dose of 2 MAC, didn't affect the contractile response while both halothane and enflurane decreased the contractile response even at the dose of 1 MAC. The potentiation of contractile responses by NOS inhibitors were not affected during administeration of IA. CONCLUSIONS: From these results, it is suggested that isoflurane is the safest inhalational anesthetic and NOS inhibitors, especially L-NAME, may be very useful in the therapy of septic shock patients during general anesthesia.

Recent technological advances in ultrasound instrumentation have resulted in equipment that will image in "real-time" slices of the human brain similar in quality to computerized tomography(CT). Multiple authors have attested to its usefulness in locatin, characterizing, and facilitating in the biopsy or removal, or both, of intracerebral masses. In this study, the author has examined the efficacy of intraoperative neurosurgical ultrasound in 18 patients who were admitted to the Department of Neurosurgery, Kyung Hee University Hospital. The results were as follows : 1) It can provide critical assistance in precise localization of subcortical masses, since in many instances the overlying surface of brain provides no clue for localization. 2) This technique is very useful for the identificantion of deep lesions, provding infromation about their solid and cystic components and about the shortest route of access to tumor. 3) It provides precise information to help guide biopsy needles into deep lesions, and to confirm their presence within the lesion itself. 4) The system is highly accurate in visualizing ventricular catheters during and after their placement. 5) The system is inherently safe for the patient and the operating room personnel since there is no radiation exposure.

The hemostatic effect of endoscopic microwave coagulation method for upper gastrointestinal bleeding was evaluated clinically. Hemostasis over 72 hours was achieved in 18 of 20 cases (90%) with upper gastrointestinal bleeding by the endoscopic microwave coagulation method. It is noteworthy that this method was effective in all 4 cases of pulsatile bleeding from exposed vessels. We conclude that this method is useful for emergency endoscopic hemostasis on upper gastrointestinal bleeding, especially bleeding from exposed vessels.

This study was carried out to find out changes in regional cerebral blood flow(r-CBF) in relation to(i) clinical status of patients with subarachnoid hemorrhage due to ruptured intracranial aneurysms ; (ii) the degree of subarachnoid hemorrhage as indicated by brain CT scanning ; (iii) the severity of angiographic vasospasm, and (iv) other neuropathological condition. Measurement of r-CBF were performed, using 133Xe inhalation method, on 50 patients with ruptured intracranial aneurysms. Some of the major findings were as follows : 1) The degree of abnormalities of blood flow correlated well with the clinical severity of neurological deficits. 2) A marked reduction in r-CBF was found in patients with intracerebral hematoma, ischemic lesion and hydrocephalus. 3) In angiospasm area, r-CBF was found in patients with intracerebral hematoma, ischemic lesion and hydrocephalus. 3) In angiospasm area, r-CBF decreases below 30ml/100gm/min in almost all of the patients, and severity of vasospasm correlated with the decrease of CBF. 4) The measurement of CBF on patients with subarachnoid hemorrhage was thought to the useful for foreseeing the clinical outcome of the patients.

We have performed experimental bilateral partial nephrectomy in 7 mongrel dogs. The technique of procedure was as follows. Renal capsule in lower renal pole was stripped and then 2-O chromic catgut suture was placed in circumferential manner around the lower pole of the kidney and guillotine amputation(Williams et al., 1967) was performed. Mattress suture, 4-5 stitches, was done on the renal parenchyme 0.2-0.3cm above edge of the guillotine ampution of the lower pole of the kidney. The gross finding of the kidney and possible complications have been observed for 3 weeks after bilateral partial nephrectomy. For microscopic observation, the tissues from the lower pole of the kidney (1x1cm) were fixed in 10% neutral formalin solution. Blood urea nitrogen level was examined on the 3rd, 7th, 14th and 21th days after bilateral partial nephrectomy. 1. The technique was relatively easy, bleeding during operation was scanty and postoperative hemorrhage was not found. 2. Major gross finding of kidney for 3 weeks after the operation was necrosis. 9 out of 14 kidneys were normal but necrosis had occurred in 5 cases. 2cases were locali2ed and minimal but S cases showed wide necrosis in the lower portion of the kidney. Urinary fistula and hemorrhage were not found. 3. Microscopic changes 3 weeks after the operation, showed necrosis, calcification. hemorrhage and fibrosis in the lower portion of the kidney. 4. BUN level was elevated maximally in 3rd or 7th day after the operation but it was decreased end had returned to nearly normal range it 3 weeks after the operation. One case showed finding of uremia by BUN elevation but this had recovered 3 weeks after operation.
