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.

The author have performed, from June to July 1976, a Sociomedical study on the 314 prostitutes which was engaged in tourism in Dongrae, Busan. The obtained results were as follows ; 1. Age distribution was from 20 years old to 34 years old and the highest as 36.6% was 23-25 years old group. Most of the respondents as 95.2% were under 31 years old group. 2. distribution of respondents by educational level showed that the group below the graduated primary school was 47.2%, middle school 29.3%, and high school 57.0% in that order. 3.

During 2 months from December 1979 to January 1980, Medical practitioners in chonnam province were grouped into Si (city), Eup(town) and Myun (rural area) groups according to the locations of their clinic. 40 practitioners were randomly selected in each group and were asked their opinions about rural medical care in general. Total of 88 practitioners replied to the question as 73.3 percent of response rate in average. The most frequently mentioned advantages of rural practice were ease of clinic opening in Si-and Myun-group respondents and good social relationship in Eup-group respondents. The most frequently mentioned disadvantages were medical isolation in Si-group respondents and resident's ignorance in medicine in Eup-and Myun-group respondents. In all groups, most respondents though that rural medicine care should be delivered by and controled by physician. Suggestions made by Eup-and Myun-group respondents for improving rural medical care by structural change focused on the regional medical insurance system, while Si-group respondents noted district hospital or hospital linkage as most preferable system.

OBJECTIVES: Risperidone is a new antipsychotic drug developed to overcome the therapeutic limitation of conventional antipsychotics. It responses to negative as well as positive symptoms by blocking both dopaminergic and serotonergic receptors, causing no significant side effects such as agranulocytosis and seizure. It is, however, not known whether it induces any serious cardiovascular side effects as evoked by other conventional antipsychotic drugs. The aims of this study were to evaluate the effect of risperidone on cardiovascular function, and to discuss the factors affecting the cardiovascular function. METHODS: For 42 patients(22 males and 20 females) diagnosed as schizophrenia, schizophreniform disorder or schizoaffective disorder according to the DSM-IV classification, the cardiovascular fuctions such as heart rate, systolic and diastolic blood pressure, PR interval, QRS interval and QT inerval were successively checked before and after 2 weeks and 4 weeks risperidone administration. Furthermore, variables such as body weight, Brief Psychiatric Rating Scale(BPRS), Clinical Global Impression(CGE), Extrapyramidal Symptom Rating Scale(ESRS), Anticholinergic Rating Scale(ARS), serum cholesterol level, serum triglyceride level, serum high-density-lipoprotein level, serum WBC, serum Hb, serum platelet level, prothrombin time and partial thromboplastin time were also analyzed before and after 2 weeks and 4 weeks risperidone administration. RESULTS: 1) Risperidone treatment resulted in a significantly decreased heart rate and increased QT interval after 4 weeks administration(p<0.005 respectively). 2) The scores of BPRS and CGI were significantly decreased after 2 weeks and 4 weeks risperidone adminisration as compared with baseline(p<0.001 respectively). The scores of ESRS and ASRS were significantly increased after 2 weeks and 4 weeks risperidone administration as compared with baseline(p<0.001 respectively). 3) There were positive correlations between heart rate after 4 weeks and total dose(p<0.05). Blood pressure was significantly(p<0.05) correlated with sex(higher in male) and significantly(p<0.05) positive correlated with body weight. QT interval was significantly(p<0.05) correlated with sex(longer in female) and smoking history(shorter in smokers). CONCLUSIONS: Risperidone could induce significant change in heart rate and Q-T interval. Therefore, the cardiovascular safety for risperidone should be reconsidered according to the duration and dosage increase.

Serum samples from 123 males and 123 females collected by age in 1996 were analyzed for antibodies against surface antigen of Hepatitis B virus and C22-3, C200 antigens of Hepatitis C virus. Sera from the children under the age of 10 showed 30% seropositivity to the surface antigen of Hepatitis B virus, 33.3% in 10~19 year group, 20% in 20~29 year group, 17.6% in 30~39 year group, 3.3% in 40~49 year group, 5.9% in 50~59 year group, 8,3% in 60~69 year group, 2.9% in 70~79 year group, but antibody could not found in 80~86 year group. 12 out of 123 male sera were positive, 19 out of 123 female sera were positive and overall rate of positivity of antibody against surface antigen of Hepatitis B virus was 12.6%. Serum samples from peoples under the age of 30 had not antibody against C22-3, C200 antigens of Hepatitis C virus. The positivity rate was 2.9% in 30~39 year group. 5 out of 30 sera from 40~49 year age group were positive, and 3 positive sera showed extremely high titer (1:524,288) but the titers of two remaining sera were 1:32, 1:8,192 respectively. 5.9% was positive in 50~59 year group, 8.3% in 60~69 year group, 11.8% in 70~79 year group but all negative in 80~86 yea. group. 6 out of 123 male sera were positive (4.9%), 9 out of 123 female sera were positive (7.3%). Overall .ate of positivity of antibody against C22-3, C200 antigen of Hepatitis C virus was 6.1%. None out of 246 sera had both antibodies against Hepatitis B virus and Hepatitis C virus.

In the previous review, the physical aspect of heavy particles, with a focus on the carbon beam was introduced. Particle beam therapy has many potential advantages for cancer treatment without increasing severe side effects in normal tissue, these kinds of radiation have different biologic characteristics and have advantages over using conventional photon beam radiation during treatment. The relative biological effectiveness (RBE) is used for many biological, clinical endpoints among different radiation types and is the only convenient way to transfer the clinical experience in radiotherapy with photons to another type of radiation therapy. However, the RBE varies dependent on the energy of the beam, the fractionation, cell types, oxygenation status, and the biological endpoint studied. Thus this review describes the concerns about RBE related to particle beam to increase interests of the Korean radiation oncologists' society.

Anti-HLA antibody related neonatal thrombocytopenia is an uncommon disorder caused by platelet antigen incompatibility between mother and fetus in Korea. Mothers who lack the specific platelet antigen produce the IgG against the platelet antigen which the fetus inherits from the father. These IgG antibodies are then transported across the placenta into the fetal circulation where they lead to the destruction of fetal platelets. We report a case of neonatal alloimmune thrombocytopenia related with anti-HLA antibody in second baby of dizygotic twin who had petechia on trunk and platelet count 43,000/mm. Initially, mother and twin showed the positives in antiplatelet antibodies. In microlym- phocytotoxic test at 6 months of age, anti-HLA antibodies was negative in twins but anti-HLA A2, A24 was positive in their mother. The patient was treated with intravenous immunoglobulin and clinically improved and her platelet count was norrnalized.
