Plasmid vectors with either RSV or CMV promoter are frequently used for DNA- mediated immunization due to the availability in commercial. Consequently, influence of the vector constituents, such as promoter, enhancer and transcription termination signal etc. on vaccination efficiency is not studied extensively. As an initial attempt to develop an efficient vector system for DNA-rnediated immunization, influence of promoter for antigen gene expression on vaccination efficiency has been analyzed. Initially, plasmids with either B-actin or muscle creatine kinase (MCK) promoter were constructed from the plasmid with prototype CMV promoter. In addition, ovalbumin (OVA) antigen gene has been cloned into each vectors to generate the plasmid vectors with different promoters for induction of the anti-OVA immune responses. Antigen protein expression in antigen gene transfected mouse muscle myoblast cells showed that the level from MCK promoter containing plasmid was slightly higher than those from either CMV or B-actin promoter containing plasmids. Also, the same plasmid turned out to be slightly more efficient than other plasmids in antibody imrnune response induction in vivo, when they were applied both through intramuscularly and intradermally. These results suggest that the commonly used CMV promoter containing plasmid vector could be further modified to develop an efficient vector for DNA-mediated immunization.

Methemoglobinemia can be caused by dapsone toxicity. We report a case dapsone induced methemoglobinemia unresponsive to methylene blue successfully treated by exchange transfusion. A 52-year-old male ingested a handful of dapsone. He presented with severe peripheral cyanosis in lips and fingertips and his methemoglobin level was found to be 21.9%. After admission, methylene blue (1%) at 1 mg/kg was injected each time peripheral cyanosis and rising serum methemoglobin occurred. Despite methylene blue therapy, the patient's methemoglobin level continued to fluctuate. Five days after the injections of methylene blue, many Heinz bodies were visualized in the peripheral blood, suggestive of hemolytic anemia occurrence. By hospital day 6, serum methemoglobine levels were elevated and not measurable (> 50%) and the patient was constantly in a semi-comatose mental state. An exchange transfusion carried out by utilizing 6 units of packed red blood cells and 4 units of fresh frozen plasma was performed. The patient's methemoglobin levels were subsequently kept up below 20% and his peripheral cyanosis receded. Physicians should recognize the important role of exchange transfusion in refractory dapsoneinduced methemoglobinemia.

This study empirically examined the actual level of elementary school children's knowledge of nutrition and the extent of current nutrition education for the children through the use of textbooks. Two or three classes were sampled from each of six schools, respectively, in Gangneung; of the 562 questionnaires that were distributed, 537 were returned and used for analysis. Respondents were all sixth-graders, on average boys and girls were 153.02+/-8.19cm and 152.79+/-7.15cm in height and 45.27+/-10.32kg and 43.33+/-7.46kg in weight, respectively, which was consistent with others' research. Most children had two siblings and a working mother, considered that they were well off, and their mother prepared meals. Children regularly had breakfast and dinner, although more children had dinner than breakfast. As a whole, their knowledge of the main nutrients contained in foods was lower than their general knowledge of nutrition. There were significant differences in knowledge of the main nutrients contained in foods, with girls showing more knowledge than boys (p<0.01). Most of them learned about nutrition at school, followed by home. At school, Practical Technology classes taught them the most about nutrition. Although Physical Education classes were expected to teach about nutrition in a quantitative way, they accounted for just 4.7% of the overall knowledge. As for the children's understanding of nutrition education through use of a textbook at school, just 19% of the students gained a very good understanding. As for interest in nutrition education at school, 22.2% of the students had no interest, while girls were more likely to have their interest in nutrition education at school affected by knowledge of nutrition than boys. For both boys and girls, the most desired method of education was cooking practice. More research across subjects is necessary so that nutrition education concentrated on the curriculum for fifth-graders can be provided by stages from the lower grades. Since cooking practice or games were preferred, it is necessary to develop nutrition education methods to incite active interest rather than passive education.

This study evaluated the effect of dagassing on the ceramic bond strength of two Ni-Cr alloys under varying holding time at the upper limit temperature and atmospheric conditions. Metal specimens were divided into 5 groups for each alloy according to degassing conditions prior to porcelain application : no degassing, degassing under vacuum without hold, degassing under vacuum with hold for 5min. and 10 min. respectively at the upper limit temperature and degassing in air. Total number of metal ceramic specimens was eighty and each group had eight specimens : The ceramic bond strength was measured by four-point flexural test using Instron and the fractured surface was examined under SEM. The results obtained were as follows. 1. Degassing in air improved the ceramic bond strength of Ni-Cr alloys. 2. in degassing under vacuum, hold at the upper limit temperature was advantageous to the ceramic bonding of Ni-Cr alloys. 3. After ceramic metal bond test, metal surfaces were partially covered with the thin porcelain layer, and the cohesive failures in porcelain were predominant in groups showing higher ceramic bond strength.

Complications of penile prosthesis include malfunction, infection and patient dissatisfaction. Herein, a rare complication of a retained reservoir having eroded into the bladder after the removal of the penile components of a three-piece penile prosthesis, is reported. A 39-year-old man complained of irritative voiding symptoms. The symptoms had developed 4 years after the removal of the penile components of the prosthesis. The erosion of the reservoir into the bladder was discovered incidentally during the treatment of bladder calculi. The reservoir was removed by an open vesicolithotomy.

A modern development of ambulatory ECG monitoring gave great advances in the diagnosis and evaluation of various cardiac conditions. Fifteen cases of ischemic heart disease, 11 cases of nonischemic heart disease, 5 cases of noncardiac disease and 9 cases of normal healthy subjects were studied from January 1980 to July 1981 in national Medical Center, with the following results: 1) The heart rate was decreased during night time, with less decreasing tendency in patients with ischemic heart disease. 2) Among 30 cases, including 12 patients with ischemic heart disease, who didn't show arrhythmia on routine 12 lead ECG, 12 cases, including 6 patients with ischemic heart disease, showed arrhythmia on Holter monitoring. 3) Among 5 cases with ischemic heart disease who showed premature ventricular contraction on day time monitoring, 2 cases didn't show premature ventricular contraction on nigh time monitoring. 4) The S-T segment and T wave were changed during night time in 2 cases with ischemic heart disease and in 2 normal subjects. From these results, we could assert that Holter monioring or ambulatory ECG tracing would be a good method for diagnosis and evaluation of ischemic heart disease, and other cardiac conditions. Several another studies with this equipment have to be performed and would give more distinctive outcomes.

Iridocorneal endothelial syndrome is a disease characterized by corneal endothelial degeneration, corneal edema, peripheral anterior synechia, iris stromal change, and secondary glaucoma. This syndrome is considered to have three major variations: Chandler's syndrome, progressive (essential) iris atrophy, and Cogan-Reese syndrome. We experienced three cases of iridocorneal endothelial syndrome with transient intraocular pressure elevation.

PURPOSE: This study was conducted to evaluate the effect of IVIG infusion on renal function in VLBW infants. IVIG has been proved quite safe in neonates given prophylactic and therapeutic doses. But nephrotoxicity is not recognized as adverse in IVIG therapy, only several previous adult cases have been noted. METHODS: For a total of ten VLBW infants who had not been received any medication except parenteral nutrition, vitamin and Fe supplements was assigned for study. To observe changes in renal function after preventive dose of IVIG administration(500mg/kg, 1dose) serum BUN and creatinine, 2-microglobulin( 2-MG) and N-acetyl- -D-glucosaminidase(NAG) were obtained prior to study and 1, 3 and 7 days after infusion. RESULTS: 1) There were no elevation of serum BUN and creatinine after IVIG administration, 2) There was transient increase of urine NAG from 1.1+/-0.7 u/mg creatinine before infusion to 2.7+/-5.3 u/mg creatinine on the first day of infusion, which was not statistically significat, decreasing to pretreatment level on the 3rd and 7th days after infusion. 3) There was transient increase of urine 2-MG from 294.6+/-223.8 microgram/mg creatinine before infusion to 680.0+/-108.9 microgram/mg creatinine on the first day and 416.0+/-246.3 microgram/mg creatinine on 3rd day after infusion, which was not statistically significant. CONCLUSIONS: It was found that prophylactic dose of IVIG in VLBW infants does not cause clinically significant impairment of renal function. but mild increment of urine NAG and 2-MG may suggest the possibility of renal tubular damage. Based on these results, further evaluation of the effect of IVIG on renal function in VLBW infant is recommended.
