BACKGROUND: In patients with endometrial carcinoma, preoperative evaluation of exact staging has important prognostic and therapeutic implications. The incidence of pelvic and aortic lymph node involvement in endometrial carcinoma depends on grade of tumor differentiation and depth of myometrial invasion. MATERIAL AND METHOD: To evaluate whether MRI provides a preoperative assessment for staging of endometrial carcinoma, MRI was undertaken in 28 patients, a few weeks before operation. Myometrial invasion was devided in three categories, and involvement of cervix, adnexa, and pelvic cavity were classified. RESULTS: The results of MR imaging were compared with these of pathology. The preoperative MRI staging of endometrial carcinoma was correct in 22 out of 28 patients. In the evaluation of myometrial invasion, the MR imaging underestimated in 4 cases and overestimated in 1 case. CONCLUSION: In patients with endometrial carcinoma, MR imaging is very useful in the assessment of the depth of myometrial invasion, stromal invasion of cevix, lymphatic & pelvic metastases and extent of the lesion.

Syringoma is not a uncommon tumor of the skin. It is a benign adenoma, of intraepidermal eccrine ducts. It occurs predominantly in women at puberty or adolescence. The lesions usually are multiple and small, skin colored or slightly yellowish payules, usually only 1 or 3mm in size. The lesions usually are limited to the lower eyelids but may occur on cheek, axilla, abdomen, neck, anterior chest and vulva. Rarely these are generalized in distributior. A 23 years old healthy man has had widespread lesions over the face, anterior chest and abdomen. The lesions appeared at the age of 13 on the anterior chest and abdomen. These increased in number and extended slowly to the face On visiting our department, there were numerous, angular or round, skin colored papules on his face and anterior chest as well as yellowish brown colored papules on his abdomen. Diagnosis was confirmed by clinical and histopathological findings as generalized syringoma.

BACKGROUND: This study was performed to determine the effect of a endotracheal intubation & induction of anesthesia using propofol 2.0 mg/kg or 2.5 mg/kg and fentanyl 2 g/kg without succinylcholine chloride. Also we have compared this method with technique using succinylcholine 1.5 mg/kg and thiopental sodium 5 mg/kg. METHODS: They were divided into 3 groups as follows: group 1, succinylcholine 1~1.5 mg/kg and thiopental sodium 5 mg/kg; group 2, propofol 2 mg/kg and fentanyl 2 microgram/kg; group 3, propofol 2.5 mg/kg and fentanyl 2 microgram/kg. Systolic arterial pressure (SAP) and diastolic arterial pressure (DAP), and heart rate (HR) were measured before induction, after induction, after tracheal intubation immediately, at 1, 2, 3, and 5min. after tracheal intubation in all patients. The incidence of adverse effects and the quality of condition for intubation were measured in all patients. RESULTS: There were significant increases in SAP, DAP, HR after intubation in group 1 but significant decreases in SAP, DAP after induction and at 5min. after intubation in group 2 and group 3. The incidence of adverse effects, and the quality of condition for intubation were no significant difference between group 1 and group 3. CONCLUSIONS: From the above result, use of propofol 2.5 mg/kg and fentanyl 2microgram/kg provided a satisfactory alternative to succinylcholine and thiopental sodium for rapid sequence induction of anesthesia.

Primary serous papillary carcinoma of the peritoneum is a rare neoplasm arising from the mesothelium. Histologically it is indistinguisable from ovarian serous papillary carcinoma, but it should be free of tumor or involved only superficially with the ovary. Radiologically its common findings are peritoneal and omental masses with ascites, and it is indistinguisable from peritoneal carcinomatosis or malignant mesothelioma. We report a case of surgically proven primary serous papillary carcinoma of the peritoneum in a 63-year-old woman.

Primitive neuroectodermal tumor (PNET) is relatively uncommon, arising outside the central nervous system. Very rarely, it occurs within the urinary system. A 55-year-old woman presented with gross hematuria and right flank pain which had begun two months earlier. A well-marginated, low-density mass containing high-density portions representing hemorrhage was seen in the right kidney at pre-enhanced CT; contrast enhancement was not prominent. At both T1- and T2- weighted MR imaging, a multilocular cystic mass with high signal intensity portions representing hemorrhage was observed. Contrast enhancement was absent. We report the radiologic findings in this case of renal PNET.

OBJECTIVES: Changes of GABAergic neurotransmission in response to the application of different types of environmental stress have been the subject of research for over two decades. However, the nature of the changes induced by stress appear to show a dependent phenomena on the type and duration of stressor agent employed. METHODS: For this reason, this study was performed to observe the effects of repeated stress on the radioligands binding to GABA A/benzodiazepine receptors of discrete brain regions. The author also examined the activity of GABA transaminase and the concentration of endogenous GABA. Male Sprague-Dawley rats, weighing 150-200g were forced to suffer an immobilization stress for 2 hours during 14 consecutive days. RESULTS: Repeated immobilization stress decreased the binding of [3H]flunitrazepam on the benzodiazepine receptor in the cortex, hippocampus and hypothalamus. Saturation experiments followed by scatchard analyses of the results showed decreased density of benzodiazepine receptor and the affinity remained unchanged. Repeated immobilization stress did not affect the binding of [3H]muscimol on the GABAA receptor, the activity of GABA transaminase, and the concentration of endogenous GABA in the brain regions. CONCLUSIONS: From these results, it can be concluded that repeated immobilization stress modulated GABAergic neurotransmission via downregulation of the benzodiazepine receptor in the brain.

PURPOSE: To determine the time of magnetic resonance(MR) signal intensity changes in denervated skeletal muscle and to compare MR imaging with electromyography(EMG) in the evaluation of peripheral nerve injury. MATERIALS AND METHODS: We evaluated MR imagings of denervated muscles after experimental transection of the sciatic nerve in five rabbits using 1.0T MR unit. MR imaging and EMG were performed 3 days and 1, 2 and 3 weeks after denervation. T1-weighted images(T1-WI), T2-WI and Short Tau Inversion Recovery(STIR) images were obtained. The signal intensity (SI) of muscles in the denervated and normal sides were visually and quantitatively compared. After measuring the SI of the normal and abnormal areas, the time of SI change was determined when there was significant difference (P<0.05) of SI between the normal and denervated sides. RESULTS: On STIR images, two of the five rabbits showed significant SI changes at the third day(P<0.05) and all showed significant changes(P<0.05)at the first week. On T2-WI, one rabbit showed significant SI changes at the third day, and all showed significant SI changes at the first week. On T1-WI, significant SI changes were seen in one rabbit at the second week and in one at the third. One week after denervation, all showed denervation potential on EMG. CONCLUSION: This study suggests that MR imaging using STIR images is a useful method in the evaluation of denervated muscle, and that MR signal changes of denervated muscle may precede EMG changes after denervation. To localize and to determine the severity of the peripheral nerve injury, future analysis of the distribution of abnormal MR SI in denervated muscles would be helpful.

It has been known that dilated cardiomyopathy(DCM) is characterized by systolic dysfunction of left ventricle(LV), but there were few studies about correlation between LV systolic function, diameter and diastolic function measured by echocardiography and radionuclide ventriculography(RVG) The purpose of this study is to evaluate LV systolic and diastolic function as well as RV function using regional ejection fraction and functional images by RVG in 17 patients with DCM and to compare these variables with echocardiographic data. The results are as follows : 1) DCM showed diffuse systolic and diastolic dysfunction of LV. The systolic impairment is accounted for the diastolic impairment in DCM. 2) The increased standard deviation of phase angle of left ventricle(LVSDph) revealed LV asynchronous contraction in DCM. 3) LVSDph showed significant correlations with other RVG parameters such as LV ejection fraction, and peak ejection rate, peak filling rate and also with LV systolic and diastolic diameter measured by echocardiography. It is concluded that LVSDph may be useful in evaluation of LV systolic and diastolic function in patients with DCM as well as LV asynchronous contraction.

BACKGROUND: Congenital nephrogenic diabetes insipidus (NDI) is a rare inherited disorder, in which two different hereditary forms, X-linked and autosomal recessive traits, have been identified. The X-linked recessive form, mostly (>90%) congenital NDI, has been known to be caused by mutation of the arginine-vasopressin receptor 2 (AVPR2) gene. AVPR2 mutation sites are different in ethnic groups and recently 72 different mutation sites have been reported among AVPR2 gene. This study aimed to analyze AVPR2 gene in selected members in a Korean family with NDI and provided a report of the existence of a new mutation site in AVPR2 gene. METHODS: Three-generation maternal pedigree of the index patient (21-year old male, patient I) and his younger brother (19-year old male, patient II) with NDI was collected. Genomic DNA was obtained from patient I, II, III (index patient's male maternal cousin with NDI), index patient's mother, three maternal aunts, one female maternal cousin and, for control, one healthy male volunteer. Three coding exons of AVPR2 gene were amplified by PCR using 4 pairs of oligonucleotide primers. After direct sequencing of amplified PCR products, the sequence was compared with whole squence of normal AVPR2 gene and identification of a new site of mutation in this gene was done. RESULTS: 1) all three male patients had transversion of G to C at position 1033 of the AVPR2 gene, resulting in a subsequent change of amino acid from glycine to cysteine in codon 201. 2) Two small peaks of G and T, the result of direct sequencing in five female members in this family, would suggest that they are carriers of G to N transversion. CONCLUSION: These results can demonstrate the significant functional correlation of the mutation in AVPR2 gene sequence with clinical NDI, and suggest the clinical utility of direct mutation testing for congenital NDI in family.
