To evaluate the relationship between eating behavior and neurotic trait in middle school students, the authors applied eating scale, Middlesex Hospital Puestionaire and Zung's self-reting depression scale to 419 middle school students(male : 187, female : 232) in Taegu city in 1993. There was no significant relationship between weight devided groups. Female middle school students showed significant high scores(p<0.05) in all scales compared to male middle school students. The correlation between eating scale and the other two scales showed significant correlationship(p<0.05) Among psychosocial factors, the items related to dissatisfaction to present and future self image(each p<0.05, p<0.05), dissatisfaction to present environmental status(p<0.05) and dissatisfaction to future attitude showed significant high score in both sex. The item related to dissatisfaction to present interpersonal relationship (p<0.05) showed significant high score in male middle school students. The items related to eat consumption rate of 61-90% (p<0.05), unsatisfied to relationship with family(p<0.05), unsatisfied to childhood family atmosphere(p<0.05), unsatisfied to past self image(p<0.05) and unsatisfied to present relationship between parent(p<0.05) showed significant high score.

The gene encoding F protein of CBP-1 strain, a heat-stable Newcastle disease virus (NDV) isolated from the diseased pheasants in Korea, was characterized by reverse transcription-polymerase chain reaction (RT-PCR), nucleotide and amino acid sequences. Virus RNA was prepared from the chorioallatoic fluid infected with NDV CBP-1 virus and cDNA was amplified by RT-PCR, cloned and sequenced to analyze. The PCR was sensitive as to detect the virus titer above 25 hemagglutination unit. 1.7kb (1,707bp) size of the cDNA was amplified and cloned into BamHI site of pVL1393 Baculo transfer vector. The nucleotide sequences for F protein were determined by dye terminator cyclic sequencing using four pairs of primers, and 553 amino acid sequences were predicted. In comparison of the nucleotide sequence of F gene of CBP-1 with those of other NDV strains, the homology revealed 88.8%, 98.5% and 98.7% with Kyojungwon (KJW), Texas GB and Beaudette C strains, respectively. As the deduced 553 amino acid sequences of F protein of CBP-1 were compared with those of other NDV strains, the homology appeared 89.9%, 98.7% and 98.9% with KJW, Texas GB and Beaudette C strains, respectively. The putative protease cleavage site (112-116) was R-R-Q-K-R, indicating that CBP-1 strain is velogenic type. The amino acid sequences include 6 sites of N-asparagine-linked glycosylation and 13 cysteine residues. These data indicate that the genotype of CBP-1 strain is more closely associated with the strains of Texas GB and Beaudette C than KJW strain.

A Dieulafoy's lesion is an uncommon, but important, cause of gastrointestinal bleeding. It is associated with massive, life-threatening hemorrhage and is typically difficult to diagnose. Although originally described in the stomach and rarely found below the proximal stomach, identical lesions have been reported in other gastrointestinal organs, including the duodenum, jejunum, colon, and rectum. Most cases occur with bleeding in the gastrointestinal tract. However, we present an incidental asymptomatic Dieulafoy's lesion in the colon, which was treated successfully by using an endoscopic hemoclipping technique.

OBJECTIVE: The purpose of this study are to evaluate the effectiveness of Gamma Knife radiosurgery(GKS) as a treatment of craniopharyngioma and to investigate the proper dose planning technique in GKS for craniopharyngioma. METHOD: Between May 1992 and March 1999, seven Gamma Knife radiosurgical procedures were done for residual tumor mass of 6 patients with craniopharyngioma after microsurgical resection. Conventional radiation therapy was not performed. In this study, their clinical, radiological and radiosurgical data were analyzed and the radiation dosage to the optic pathway, hypothalamus, pituitary stalk, and cavernous sinus were calculated and correlation with clinical outcome was evaluated. The mean follow-up period was 33.5 months(12.3-55.2 months). RESULT: The mean tumor volume was 4.4cc(0.4-18.0cc) and the maximum radiation dose ranged from 14 to 32 Gy(mean 20.9Gy). The radiation was given with isodose curve, 50-90% and the marginal dose varied within 8-22.4Gy(mean 12.7Gy). The mean number of isocenter was 4.3(1-12). The tumor was well controlled in all cases. In 5 of 7 cases, the size of tumor decreased to 10-50% of pre-GKS volume and remaining two showed no volume change. The mean dose to optic pathway was 5.7Gy(5.1-11.2Gy) and there were no complications. CONCLUSION: GKS seems to be effective for control of craniopharyngioma as an adjuvant treatment after microsurgical resection and even suboptimal dose for tumor margin is considered to be enough for tumor control. It is safe with careful dose planning to protect surrounding important structures, especially optic pathway. We believe conventional radiation therapy should be avoided because it has limitation for dose planning of additional treatments such as radiosurgery or intracystic instillation of radioisotope in case of recurrence.
