BACKGROUND: Though symptomatic improvements after treatment of donepezil is well documented in Alzheimer's disease (AD), the electrophysiological change have not yet been elucidated. Among the parameters of quantitative electroen-cephalography (q-EEG), high frequency activity, especially gamma rhythm, may play a role in normal cognitive function including the integration of sensory processing, association, coupling or selective attention, which are characteristically impaired in AD. METHODS: In order to define the profile of q-EEG changes including gamma rhythm after donepezil treatment, we followed 17 AD patients for 12 weeks. We analyzed the spectra power taken from 16 derivations by averaging twenty-2-sec epoch in normal controls and AD patients. After logarithmic transformation of spectra power, statistical test was done and the effect of donepezil treatment on q-EEG profile was analyzed during follow up period. RESULTS: Before medication of donepezil, AD patients had a significantly lower alpha spectra power as well as a significant higher delta spectra power, compared with normal control. After medication of donepezil in AD patients, compared to base-line q-EEG, gamma spectra power was significantly increased, whereas delta spectra power was significantly reduced. Compared to absolute power, relative power was more sensitive in detecting change of EEG after donepezil treatment. CONCLUSIONS: This study suggests that donepezil significantly change delta and gamma spectra power in q-EEG, and the increase in gamma rhythm may be correlated with the clinical improvements after donepezil treatment.

Though topical administration of antifungal agents for fungal keratitis is effective, it results various toxic effect on cornea depending on the kinds of agents. So, the authors applied several kinds of antifungal agents on the cornea of rabbit and made a comparative study for corneal epithelial damage of which is related to each agents and instillation time using scanning electron microscope. Forty eyes from twenty rabbits were instilled with 0.15% amphotericin B, 5% natamycin, 1% clotrimazole, 0.2% fluconazole and BSS(as a control) in single drop in each eight eyes and then each two corneas resected and examined after 30 minutes, 1 hours, 3 hours and 6 hours. All antifungals showed toxic effects on the corneal epithelium. Significant loss, elongation or swelling in microvilli, especially at the cell periphery, were noted. The top layer of epithelial cells showed moth-eaten appearance or punched-out lesions, and localized destruction. The surface cells were shrunken with wrinkling of plasma membrane and bulging of nucleous. Part of surface cells lost intercellular attachment leaving retraction fibrils. Rarely first and second layer cells of the epithelium were destructed, exposing third layer cells. Dark cells and premature desquamating cells increased significantly with the lapse of time. In general, 5% natamycin and 1% clotrimazole showed relatively severe epithelial toxicity, on the other hand, 0.15% amphotericin B and 0.2% fluconazole shoed mild epithelial toxicity. Localized damages in the epithelial cells were developed in the early stage, and an extent and the depth of the damage in the cells increased in the course of time after instillation.

Priapism is an uncommon condition of prolonged painful penile erection, and no sexual excitement or desire is present. The therapeutic goal in priapism is to restore normal circulation and blood flow in the erectile tissue of corporacavernosa. In recent years medical treatment is unsuccessful and it should be treated as a surgical emergency. Here we report one case of priapism with review of related recent references.

BACKGROUND: To pass through the microcirculation, erythrocytes need to undergo considerable deformation. We performed an experiment to investigate the erythrocyte deformability in healthy adults and in patients with uncontrolled hypertension and controlled hypertension. METHODS: 5ml of whole blood is anticoagulated with 2mg ethylenediaminotetra-acetic acid(EDTA). 1ml graduated plastic syringe, without its plunger, is filled with anticoagulated whole blood to the 1ml mark, And the syringe is put into the assembled membrane holder. Under standard condition, whole blood is passed through a 5micro polycarbonate membrane filter under negative pressure of 20cm H2O. The studies are performed at roon temperature and within two hours of venipuncture. RESULTS: Erythrocyte deformability was observed in 91 normal healthy adults and 25 patients with uncontrolled hypertension and 18 patients with controlled hypertension. Following results were obtained. 1) In male control age group I, II, III, the erythrocyte deformability indices were 0.776+/-0.125, 0.792+/-0.189, and 0.714+/-0.172 respectively and in female the indices were 0.880+/-0.138, 0.865+/-0.182 and 0.796+/-0.170 accordingly. 2) THe RBC deformability indices in female control troup were significantly higher than the male group in statistics(p<0.05). 3) No significant differences were observed among each age group in control. 4) In patients with uncontrolled hypertension, each age group I, II and III, the erythrocyte deformability indices were 0.785+/-0.050, 0.775+/-0.122, and 0.692+/-0.133 respectively and in control group, the indices were 0.8365+/-0.140, 0.8252+/-0.186 and 0.7534+/-0.173 accordingly. And in patients with controlled hypertension, the indices were 0.820+/-0.00, 0.788+/-0.135 and 0.716+/-0.141 accordingly. 5) The erythrocyte deformability inddex in patients with uncontrolled hypertension were significantly lower than the control group(p<0.05), and no significant differences were observed among each age group between male and female in patients with uncontrolled hypertension. 6) There was no significant statistical difference of deformability indices between uncontrolled group and controlled group(p>0.05). CONCLUSION: This study reveals that the erythrocyte deformability in patients with essential hypertension is significantly lower than the healthy adults.

PURPOSE: We report seven cases of pancreas transplantation, first performed in Korea, in the context of postsurgical radiologic studies. MATERIALS AND METHODS: All patients with insulin-dependent diabetes mellitus received transplants from cadevaric(n=6) or living related donor(n=1). Retrospective analysis of 27 US(including 19 Duplex US), two CT, four MRi, and three scintigraphy for these patients was made with surgico-pathological correlation in five cases. RESULT:Of the seven patients, three-month graft survival was five and one-year survival was two. One patient died of abdominal abscess following surgery. US gave the valuable informations regarding the graff swelling, vascular complication, and perigraff fluid collection. RBC bleeding scan was effective of the presence or absence and location of intestinal bleeding. CT was useful in determining the extent and severity of the pancreatitis. MRI gave a little information about functional status of the grafted pancreas. CONCLUSION: The choice of appropriate imaging modalities for postsurgical work up in patients who had pacreas transplantation depends on the clinical conditions of the patients and complications suspected. Further prospective studies appear to be necessary to eatablish the interval and modality choice for early detection of the complication.

PURPOSE: To assess the role of the preoperative portal vein embolization (PVE) in patients in need of major hepatectomy. MATERIALS AND METHODS: Total of 11 cases consisted of Klatskin tumor (n:6), gallbladder cancer (n=2), and hepatocellular carcinoma (n=3). After percutaneous transhepatic puncture of portal vein (right:7, left:4), the embolization of 1st order branch of right portal vein was done with Gentamicin soaked Gelfoam cubes. Radiologically, the angle between the middle hepatic vein and the inferior vena cava was measured on pre- and post-PVE CT (F/U :10 days) to evaluate the hypertrophy of the left lobe. Clinically, amount and nature of the drained bile through the PTBD tube of both lobes were analyzed in 5 patients with Klatskin tumor. The interval between PVE & operation was 10-24 days. Operative findings & the changes of postop. total bilirubin were analyzed and the complication after procedure was checked. RESULTS: There was decrease in mean angle between the middle hepatic vein and the inferior vena cava from 35.9 degree to 23.9 degree, but it was insignificant statistically (p=0.09). The embolization of right portal vein was done and there was increase in amount of drained bile from the nonembolized left lobe by 2-3 folds 8-14 days after PVE. The color and consistency between both lobes were significantly different; right lobe was darker in color and softer in consistency. Postoperative total bilirubin increased by 2-3 folds 1 to 4 days after PVE and normalized 10 to 14 days after PVE. Most of the patients had mild abdominal pain and fever after PVE and 1 patient had localized hematoma at puncture site which was subsided spontaneously. CONCLUSION: The preoperative portal vein embolization is a useful method for minimizing postoperative liver failure in patients in need of major hepatectomy.

Aneurysm of the vein of Galen is a rare midline arteriovenous malformation, usually presenting with cardiac failure in infancy or with hydrocephalus and raised intracranial pressure in older children. We experienced a case of the vein of Galen aneurysm diagnosed with computed tomographic (CT) features and magnetic resonance image (MRI), a new imaging modality. Our case was a 3 day-old male neonate and had a nonspesific symptom of high fever without cardiac failure. A brief review of related literature was made.
