Five cases of ameloblastoma considered to be originated from the wall of the odontogenic cysts are reported. Histologic characteristics and diagnostic criteria are aimed to study in differentiation of ameloblastoma arising in odontogenic cysts from odontogenic cysts accompanying with reactive epithelial proliferation, and the literature is reviewed. This study can propose that the ameloblastic change and downward growth of epithelial cells lining the cysts are the most important and characteristic findings of the ameloblastoma derived from odontogenic cysts. In addition, the intraluminal proliferation of epithelial cells in plexiform pattern is also significant.

To elucidate the clinical characteristics-especially its clinical pattern and outcome-of children with encephalopathy, we carried out a retrospective review on medical records of 45 patients who were initially diagnosed as encephalopathy except mumps meningitis, Reye's syndome and neonatal hypoxic ischemic encephalopathy at the Department of pediatrics, Hanyang University children's hospital from Jaunary 1986 to February 1994. The results were summarized as follows: 1) Twenty five were male and twenty were female with male to female ratio 1.3:l. 2) There were no association with death rate and conscious level, abnormal liver function test, and sugar level in CSF on admission. 3) Death rate (33.3%) of group with seizure was higher than that (13.3%) of group without seizure on admission, but there was no statistical significance (p=0.28). 4) Death rate (7.5%) of group (l) which initial therapy started before 12hours was lower than that (43.4%) of group (ll) which initial therapy started after 12hours, but there was no statistical significance (p=0.09). However complete recovery rate (66.7%) of the former group was higher than that (26.7%) of the latter group with statistical significance (p<0.05). Therefore, early diagnosis and treatment before 12hours was essential to recovery and good prognosis in childern with acute encephalopathy.

We experienced a case of Rotor syndrome in an 8 year 6 month old boy who presented with icteric sclera and icteric skin on whole body. His clinical and laboratory characteristics were as follows; 1) Jaundice appeared from several months ago before admission without any clinical disturbance. 2) Direct bilirubin was more increased than indirect bilirubin. 3) Plasma indocyanine green (ICG) kinetics test revealed hepatic excretory in this patient that after intravenous injection of a standard dose of ICG (0.5mg/kg), its initial plasma disappearance is decreased, resultin in markedly increased retention of the dye 45 to 50 minutes after administration. 4) Oral cholangiography, ultrasonogram, and computed tomogram of abdomen were normal. 5) Liver biopsy specimen showed no dark brown pigmentations in the hepatic cells and any other pathologic abnormalities. 6) Nearly similar clinical and laboratory findings were observed 26 months later.

To investigate the involvement of expression of the Fragile Histidine Triad(FH1T) gene product in the process of carcinogenesis and progression in cervical carcinoma, we examined its expression by immunohistochemical method in 15 cervical invasive carcinomas, 10 low grade cervical intraepithelial neoplasias(CINs) and 30 high grade CINs(CMI and III). We detected expression of FHIT gene product in 4 of 15(27%) of invasive carcinomas, 3 of 10(30%) low grade CIN and 7 of 30(23%) of high grade CIN, while we detected expression of FHIT gene product in 28 of 45(62%) normal and metaplastic epithelium near the tumor. Thesc data indicate that loss of expression of FH1T gene product has some role in the early tumorigenesis of uterine cervical carcinoma, but not the consequence of the pregression of the tumor.

The eosinophil is the major cell responsible for the inflammatory reaction in bronchial asthma. Secretion of granular components is probably of considerable importance for the inflammatory effects of the eosinophils. Eosinophil cationic protein (ECP) is the one of the secretory components of the eosinophil granule and-is considered as an activation marker of eosinophil count, serum concentration of ECP and serum IgE were studied in normal, symptomatic and asymptomatic asthmatic children. In symptomatic asthma, peak expiratory flow rate (PEFR) was studied and methacholine challenge test was done in asymptomatic asthma in addition. Blood eosinophil count and serum ECP in asthma were significantly raised compared with those of the normal children. And the level of serum ECP in symptomatic asthma was higher than that in asymptomatic asthma. The mean % fall of PEFR was significantly correlated with serum ECP and blood eosinophil count in symptomatic asthma. In asymptomatic asthma, there was no correlations between methachloine PC20 and blood eosinophil count or methachloine PC20 and serum ECP level. Our findings show that blood eosinophil count and serum ECP levels differ not only between normal children and asthmatic children, but also between symptomatic asthma and asymptomatic asthma.

Intralesional belomycin injection has been an effective treatment of recalcitrant warts since 1970. A 1 U/ml solution of bleomycin sulfate in normal saline or lidocaine solution was injected intralesionally in 72 warts of 33 patients on the hands, forearm, feet, and face. Dosage of bleomycin was dependent on the size of warts, usually 0.1 to 0.15 cc of solution. All patients was permitted to wash the treated area without care. 59 (81.9%) of 72 warts were cured after one injection, 12 (16.7%) warts after two or three bleomycin injections. One large wart was not cured. Most patients experienced minimal painful discomfort for two to three days after one to two days of injection, but did not take the analgesics. There was no evidence of systemic and local toxicities. The most responsive warts shoed hemorrhagic black eschars that separated after 2 to 3 weeks and healed with very little or no scar tissue. Intralesional bleomycin injection is a reliable and useful alternative for the treatment of warts.
