BACKGROUND: Interferon alpha-2a has already been shown to be effective in clinical use of virus-originated diseases such as hairy cell leukemia, condyloma acuminatum, and AIDS-related Kaposi's sarcoma. The use of recombinant alpha-interferon may allow common warts to be treated relatively atraumatically and with less incidence of recurrence. OBJECTIVE: We tried to determine the safety and effectiveness of intralesional injections of recombinant alpha-2a interferon in the treatment of patients with common warts. METHODS: A single wart on each patient was weekly injected with 0.75 to 1.5×10(5) IU/25mm2 of interferon for 8 weeks, and the response to treatment was followed up-to 6 months. RESULTS: Clearing of the treated wart at the end of treatment occurred in 5(71%) out of 7 patients and the rest showed no improvement. With evaluation for relapses up-to 6 months after treatment, warts relapsed in 2(40%) out of 5 patients. Therefore, 3(43%) out of 7 patients were completely free of warts 6 months after treatment. CONCLUSION: Intralesional recombinant interferon alpha-2a has a limited therapeutic effect, but may be considered as a therapeutic modality of recalcitrant verruca or when it can be anticipated that destructive techniques or blistering agents will not be tolerated.

Characterizations of the VP4 (P type) and VP7 (G type) genes of Korean isolates of bovine rotavirus were performed using RT-PCR/RFLP and nucleotide sequencing analysis. After RT-PCR amplification of partial length (1094bp) of the VP4 and full length (1062bp) of the VP7 genes, amplified PCR products were digested with restriction endonucleases and digestion patterns were compared with those of reference rotaviruses. With the VP4 genes, four RFLP (AD) profiles were observed; three (A, B and C) were the same as those of bovine rotavirus NCDV (P[1]), IND (P[5]) and B223 (P[11]), respectively, Profile D was the same as that of porcine rotavirus OSU (p[7]). With the VP7 genes, five RFLP profiles (I-V) were observed; three of them (1, II and III) were the same as those of bovine rotavirus NCDV (G6), Cody I-801 (G8), and B223 (G10), respectively, Profile IV and V were atypical to those of reference bovine rotaviruses used in this study. These two profiles were identified as G6 and G5, respectively, after analyzing and comparing the nucleotide sequences. The G typing analysis revealed that 61.9% (26/42) were G6, which included G6 subtype; 28.6% (12/42) were G5; 7.1% (3/42) were G10; 2.4% (1/42) were G8. The P typing analysis revealed that 54.8% (23/42) were P(5); 28.6% (12/42) were P(7); 11.8% (5/42) were P(11); 4.8% (2/42) were P(1). Our results showed that G6/P(5) were the most prevalent rotaviruses in diarrheic calves in Korea. Also, this is the first report that G5P(7) rotaviruses were identified from cattle with diarrhea.

The bone mineral densities of 60 middle school boys were measured with dual photon absorptiometry to define the influence of Taekwon-Do. They were divided into Taekwon-Do and control group, each comprising 30 boys. The bone mineral densities of the head, trunk, pelvis, both upper and lower extremities, and body total were measured. The results were as follows. 1. The BMD of head was 1.668 ± 0.153 in Taekwon-Do and 1.554 ± 0.153 0.167 in control. It was significantly increased in aekwon-Do(p <0.05). 2. The BMD of trunk was 0.378 ± 0.153 0.044 in Taekwon-Do and 0.353 ± 0.153 0.053 in control. There was no significant difference(p >0.05). 3. The BMD of pelvis was 1.648 ± 0.153 0.112 in Taekwon-Do and 1.444 ± 0.153 0.215 in control. It was significantly increased in Taekwon-Do(p <0.005). 4. The BMD of right and left legs were 1.597 ± 0.153 0.118 and 1.579 ± 0.153 0.125 in Taekwon-Do and 1.425 ± 0.153 0.115 and 1.421 ± 0.153 0.113 in control group respectively. They were significantly increased in Taekwon-Do(p <0.005). 5. The BMD of right and left arms were 1.184 ± 0.153 0.090 and 1.178 ± 0.153 0.115 in Taekwon-Do and 1.056 ± 0.153 0.095 and 1.066 ± 0.153 0.097 in control group respectively. They were significantly increased in Taekwon-Do(p.<0.005). 6. The total body BMD was 0.932 ± 0.153 0.068 in Taekwon-Do and 0.846 ± 0.065 in control. It is significantly increased in Taekwon-Do(p<0.005). In conclusion, Taekwon-Do increases the total bone mineral density and the mineral densities of the head, pelvis and extremities but not that of trunk. It is thought that continued practice of Taekwon-Do throughout adult life might prevent the senile osteoporosis

Fetal hydrops is often serious and associated with a high perinatal motality rate. Cardiac causes of fetal hydrops include congenital heart diseases and rhythm disturbances. An irregular fetal heart rate may indicate atrial fibrillation and atrial flutter with variable AV conduction. Fetal atrial flutter is characterized by the pressence of flutter waves which are regular sawtooth undulations in the baseline that are larger than p waves. Authors experienced a case of fetal atrial flutter with hydrops fetalis at 30 week's gestation which was confirmed by fetal M-mode echocardiogram and electrocardiography. A new born infant had shown to have atrial flutter in utero and after delivery was successfully converted to normal sinus rhythm with digoxin and quinidene.

The Korean Society of Anesthesiologists began to take in training examination(Self Assessment) for the residents in April 1989. Two hundreds thirty four participants took the first examination and after that 343 in 1990, 399 in 1991, 455 in 1992 took the examination obviously the actual number is increasing each year. This study was done to see if there is any correlationship between the results of self assessment and board examination in the same population group. Ninety two persons who took self assessment in April 1990 and board examination in Jan 1991 and 108 persons who took self assessment in Sept. 1991 and board examination in Jan 1992 were investigated. In both groups we can see the close positive correlationships between the results of self assessment and written board examination.

PURPOSE: To characterize strain-specific differences in radiation response in murine tissues with different radiosensitivity. MATERIALS AND METHODS: Six-week old male mice of 2 strains, C57Bl/6J and C3H/HeJ, were given whole body gamma-radiation with a single dose of 10 or 25 Gy. At different times after irradiation, mice were killed and tissues with different radiosensitivity, thymus and liver, were collected. Each tissue sample was stained with hematoxylin and eosin and apoptotic cells were scored. Expression of p53, Bcl-2, Bcl-x, and Bax was analysed by western blotting and densitometry. RESULTS: Radiation induced massive apoptosis in thymus with a peak level at 8 h after radiation. With 10 Gy irradiation, apoptotic indices in C57Bl/6J and C3H/HeJ were 81.0 2.5% and 59.4 4.0%, respectively (p<0.05). Radiation upregulated the expression of p53, Bcl-x, and Bax, but not Bcl-2; p53 with a peak level of 2.5 fold (C57Bl/6J) and 1.4 fold (C3H/HeJ) at 4 h, Bax with a peak level of 2.6 fold (C57Bl/6J) and 1.3 fold (C3H/HeJ) at 8 h, and Bcl-x with a peak level of 11.1 fold (C57Bl/6J) and 8.2 fold (C3H/HeJ) at 8 h after radiation. In liver, however, radiation-induced apoptosis was minimal (peak apoptotic index of 2.1% in C57Bl/6J and 1.7% in C3H/HeJ). None of p53, Bcl-2, Bcl-x, and Bax was significantly increased. CONCLUSIONS: Induction of apoptosis and regulation of related genes by radiation were tissue specific. Strain difference of radiation-induced apoptosis was well coupled with theinduction of related genes in thymus, a radiosensitive tissue. This study shows that quantitative difference of radiation induced apoptosis by strain is regulated at the gene level with the involvement of multiple genes.

Korean Journal of Dermatology 1994;32(5):860-865
BACKGROUND: Superoxide dismutase(SOD) is an essential enzyme of protective defense mechanism in cellular compartments against the potential cytotoxicity of superoxide anion. It seems SOD activity is increased in psoriasis because of an increase in oxygen intermediates due to hyperoxia. However SOD activity is decreased paradoxically. OBJECTIVE: In order to understand the pathophysiology of psoriasis and to elucidate the significance of SOD activity in keratinocyte proliferation, we measured the SOD activities in psoriatic and in normal skin. METHODS: Authors assayed the level of SOD activities in 16 psoriatic and 16 and skin specimens, which were obtained from face/neck(1 and 4 specimens), forearm(5 and 4 specimens), trunk(6 and 3 specimens), and lower extremity( 4 and 5 specimens). We also investigated changes of SOD activity by age and regional differences of SOD activities in the psoriatic and normal skins. RESULT: First, activities of total SOD, Mn-SOD and Cu, Zn-SOD were 12.75+/-8.15, 4.28+/-3.62, 8.48+/-6.37 units/mg protein respectively in the psoriatic skin. Activities of total SOD, Mn-SOD and Cu, Zn-SoD were 17.63+/-9.10, 3.38+/-14.25+/-8.16 units/mg protein respectively in the normal skin. There as a significant difference between psoriatic and normal skins in Cu, Zn-SOD and Cu, Zn-SOD activities showed no significant differences between the age groups. Third, in sun exposed area and unexposed area, there were no significant differences between the psoriatic and normal skins in SOD activities. But it the normal skin, there were significant differences between sun exposed area and unexposed area in total SOD and Cu, Zn-SOD activities. CONCLUSION: There is a significant difference between psoriatic and normal skins in Cu, Zn-SOD activity. Namely, the Cu, Zn-SOD activity is significantly decreased in psoriasis.

Nevus sebaceus of Jadassohn has been referred to as a organoid nevus that classically evolves through three stages and may be associated with a range of skin tumors, and of these, syringocystadenoma papilliferum and basal cell carcinoma have been commonly reported to occur. The occurrence of keratoacanthoma is a very rare event in nevus sebaceus. Herein we report on a 23-year-old man with nevus sebaceus of the cheek. He represents a keratoacanthoma arising within nevus sebaceus.
