Although tubuloglomerular feedback (TGF) is involved in ureteral obstruction-induced increase in renal blood flow (RBF), its contribution to RBF is not well established due to the concommitant increases in prostaglandin (PG) and renal interstitial fluid pressure (Pisf), both of which affect RBF one way or the other. Since Pisf and TGF are closely affected by renal hemodynamics, RBF will respond differently to increases in ureteral pressure depending on renal hemodynamic conditions. Therefore, the purpose of the present study was to investigate how the changes in renal hemodynamics affect the response of RBF to increases in ureteral pressure. The effect of PG on RBF was assessed by comparing the effects obtained before and after indomethacin, a cyclooxygenase inhibitor. Six anesthetized dogs were prepared with flow probes and inflatable silastic occluder around the renal artery, the ureteral catheter with its free end attached to a water reservoir, and the arterial and venous catheters. RBFs were obtained at ureteral pressures of 0, 15, and 40cmH2O during the maintenance of the renal artery pressure (RAP) at the level of systemic arterial pressure, 10mmHg above and below the lower autoregulatory limit of RBF (65+/-4 mmHg) both before and after indomethacin administration (10mg/kg). In response to the ureteral pressure of 40cmH2O, RBF increased from 172+/-6 to 185+/-10ml/min when RAP's were equal to systemic arterial pressure and decreased from 162+/-10 to 120+/-9 ml/min when RAP's were 55+/-4mmHg. Indomethacin pretreatment, depending on the level of RAP either prevented an increase or augmented a decrease in RBF in response to ureteral pressure elevation. This suggests that RAP-dependent changes in susceptibility of the renal venous system to compression by increased Pisf is the main mechanism by which the changes in renal perfusion pressure modulate the response of RBF to ureteral pressure elevation.

Fity-four patients with head and neck cancers were prospectively examined with the CT to determine its valuein staging cervical lymph nodes metastases and to compare with the clinical staging. The CT staging agreed withthe clinical staging in 61%(33/54), upgraded the clinical staging in 22%(12/54) and downgraded in 17%(9/54). Thepost-surgical confirmation was made in only 11 patients, The possible causes of disagreement between the CT andthe clinical staging, and the diagnostic value of the CT in the evaluation of the cervical nodes metastases werediscussed.

9.Measurement of Olfactory Threshold in Normal Korean Adults with Combined Use of Bounded CCCRC Test and Step Method.

The high variability of measured olfactory thresholds in humans reflects very broad range of sensitivity within and among individuals. This can be derived from the strongly compressive nature of olfaction, which makes it relatively hard to compare the size of two stimuli in odor sensation. However, we know that some portion of the variation is the result of extrinsic factors e.g. the method used to measure the olfactory threshold. For this reason, in order to address the bias and reliability of a psycophysical method, we combined the use of the CCCRC (Connecticut Chemosensory Clinical Research Center) test with the step method in 40 normal Korean adults twice a week for the evaluation of threshold. The measured thresholds showed high test-retest reliability and the threshold estimates remained consistent during the testing without trial-biases. Based on the results, we can conclude that a combined test using the CCCRC test and step method can be used in the measurement of olfactory threshold in a clinical context.

Fibrous histiocytoma are complex group of tumors that feature cells resembling fibroblasts and histiocytes.In a case of fibrous histiocytoma involving the cornea and corneolimbus, we evaluated the finding of H-E, Masson-trichrome, reticulin, CD68, alpha-1-antitrypsin antibody and smooth muscle actin antibody stain after the localized excision in 26 years old male patient. In H-E stain, tumor cell included many multinucleated giant cells having abundant eosinophilic and foamy cytoplasm infiltreated by numerous lymphocyte, CD68 & alpha-1-antit-rypsin antibody staining resulted in diffuusely positive finding. Therefore examination. Good result was noted after complete excision at 6 month follow-up.
