One hundred and twenty male rabbits were divided into 8 groups in order to studythe effect of castration and sex hormone administration on water and electrolytesdistribution in kidney, small intestine and lung tissue as follows:Group 1: control (non castrated)Group 2: estrogen injectedGroup 3: androgen injectedGroup 4: progesterone injectedGroup 5: castration control (castrated)Group 6: estrogen injected and castrationGroup 7: androgen injected and castrationGroup 8: progesterone injected and castrationFourteen days after castration, each rabbit in groups 6, 7 and 8 was administeredwith 2,000 units of estrogen, 400 units of androgen and 400 units of progesteronddaily for 3 days consecutively. Three days after the final injection, they weresacrificed by means of cardiac puncture. Immediately after sacrificing the animals, kidney, lung and small intestine were removed to determine the contentsof tissue water. Na, K and Cl. Water content was determined by drying method in 1O0 degrees C oven until the weight remained constant. Na and K in serum and tissue wereanalyzed with Baird flame photometer using lithium nitrate as internal standard.Serum Cl was analyzed by the method of Schales and Schales and tissue Cl by theVan Slyke's. The conclusion is as follows: 1) In control rabbits (non castrated), serum concentration of Na and K was decreased while Cl concentration was increased after administration of estrogen, androgen and progesterone. 2) In castrated rabbits, serum concentration of Na was increased, while K was decreased. Na and K were decreased, while Cl was increased by the administration of sex hormone after castration. 3) In kidney tissue of non castrated rabbits, water content was slightly increased by the administration of sex hormone. The changes in concentration of Na, K, Cl. extracellular space and total Na + K were not significant, while K was increased remarkably in the progesterone group. Also the total Na + K [cell water (Na)] was remarkably increased as high as 47%. 4) In kidney tissue of castrated rabbits, water content and Na were increased, whereas K and Cl were decreased. The administration of sexhormone acted inclusively on the restoration of these levels to the precastration state. The androgen injection provided the most effective result. 5) In lung tissue of non castrated rabbits, Na and K were decreased by the administration of sex hormone. In the androgen group, a decrease of Na and K was most remarkable, Cl in the progesterone group, and Na space and total Na+K in the androgen group were decreased remarkably. 6) In lung tissue of castrated rabbits, water content was increased, and Na, K and Cl were all decreased. The administration of sex hormone acted inclusively on the restoration of these levels to the precastration state. In general, the androgen was most effective among hormones given. 7) In small intestine tissue of non castrated rabbits, Na, K and Cl were increased and also the extracellular space and total Na+K were inclusively increased. 8) In small intestine tissue of castrated rabbits, water content and K were increased while Na was decreased. The administration of sex hormone acted on the restoration to the precastration state in the water content and Na. The androgen was most effective among hormones given.

The common bile duct and the duct of Wirsung cojoin at the level of the duodenum, forming the major. papilla of Vater. Existence of a double major papilla, i.e., two neighboring independent papillary structure:, is infrequent. In our endoscopy unit we have experienced one case of double papilla of Vater wherein canulation of the common bile duct and pancreatic duct could be accom plished through either orifice independently.

OBJECTIVE: Base on clinical practice, the authors report a case of tardive dyskinesia arising during the course of treatment with resperidal. METHODS: This article was review and analysis of a case on risperidone-induced tardive dyskinea. RESULTS: Mrs K, a 51-year-old women with a 1-year history of schizophrenic disorder, gradually developed tardive dyskinetic movement of the mouth, lip, and tongue over a 4 month period(From July 1996 to June 1997) while taking risperidone. Initially she was treated with haloperidol and alprazolam. However, the haloperidol was subsequently discontinued because of EPS developed. From 11th March 1997, she was observed to have a severe form of tardive dyskinesia involving her tongue, lip, and mouth. After risperidone was withdrawn at 9th May 1997, her tardive dyskinetic movement was disappeared. CONCLUSIONS: This is, to our knowledge, the first report of the onset of tardive dyskinesia in a patient taking risperidone. However, additional controlled studies of specific questions are needed ; e.g., the dose-response curves for produce tardive dyskinesia and the mechanism of producing risperidone-induced tardive dyskinea and so on.

A 24-year old man presented with intermittent left flank pain for two years. With urograms this case was diagnosed as unilateral hydronephrosis associated with ureteropelvic obstruction. The cause of the ureteropelvic obstruction was proven as fibrous band surgically and pathologically. He underwent resection of the fibrous band and intubated pyelo-ureterostomy, and was discharged on the 14th postoperative day.

Toward the beginning of the twenty-first century, the world experiences the dramatic changes in politics, economics and culture, and it is evident that the Korean medical field will not be able to survive provided it doesn't prepare ourselves to adapt to those changes. The Korean Medical Society held a forum for the active operation of the medical society, inviting several leading affiliated societies, to meet the needs of the times. This review describes the summary of the presentation that the authors made on behalf of the Korean Radiological Society in the forum, including the organization, current status of academic activity, current status of international communication, and problems encountered in the internationalization of the Korean Radiological Society.

To evaluate characteristic CT findings of orbital pseudotumor and to define differentialpoints from other pathology, the authors retrospectively reviewed CT of 19 patients who were prooen to have orbital pseudotumor by clinical course and, in some cases, biopsy. A variety of CT findings including extraocular muscle thickening(11 cases), streaky infiltration of retroorbital fat(11 cases), mass formation(10 cases), optic nerve thickening (6 cases), conjunctival thickening (5 cases), scleral thickening(4cases), enlarged lacrimal gland(4 cases) and destruction of orbital bone (2 cases) were observed. Thickening of the anterior portion and irregular margin were characteristic findings of extraocular muscle and optic nerve lesions. Mass formation predominantly occurs in the anterior portion of the orbit. In most cases more than two orbital structures are involved by lesion.

Evaluations of residual renal function and the therapeutic effectiveness in renal tuberculosis have largely been dependent on intravenous pyelogram or Contrast-CT scan, even though, exact renal function are not evaluated with there methads. 99mTc-DMSA is a radiopharmaceutical that is trapped in the functioning tubular cells of the kidney and therefore, quantitative renal function could be evaluoted by ineasuring the counts of renal radioactivity and concomittant evaluation of renal morphology could be passible with the analog imapes of the radioactivity. The authors retrospectively analyzed 99mTc-DMSA scans of 75 kidndys of 67 patients with confirmed renal tuberculosis. We classified the morphologies of tuberculous kidneys as 6 types. We classified the morphologies of tuberculous kidneys as 6 types such as the type with small cortical defect, with parenchymal ulcerocavernous lesions, ulcerocavernous fistula to pelvis, mass-like defects, contracted kidney with ureter visualization, and the type with nonvisualization of kidney, corresponding to the characters of renal tuberculous pathogenesis with abscess formation, ulcerocavernous fistula, and fibrosis, and correspondings to the renal anatomy with parenchyma, and pelvocalyceal collecting system. Their mean residual renal functions measured with 99mTc-DMSA uptake rates were 19.0%, 18.4%, 7.9%, 12%, 4.1%, 3.4% respectively.
