Abnormalities of the short arm of chromosome 12 are relatively common in childhood ALL. Approximately 5~7% of children with ALL have cytogenetic evidence of a translocation involving 12p, whereas 3~5% have deletions which suggest the presence of a tumor suppressor gene at this location. Through the use of sensitive molecular techniques, 12p or 12p 12~13 loss of heterozygosity (LOH) has been demonstrated in approximately 25 oyo of childhood ALL cases. FISH mapping has detected a minimum region of overlap for the 12p deletions between the TEL(ETV6) and CDKN1B(KIP1) geness). Recently, chromosomal translocations involving the TEL gene at 12p13 have been cloned in several hematopoietic disorders. In ALL cells with thet(12;21)(p13;q22), the 5' part of TEL is fused with the AML1 gene. Abnormalities of 12p, especially the t(12 ; 21), are more reliably detected by FISH than by classical cytogenetics because the translocated portions 12p and 21q are virtually identical cytologically. When FISH was combined with Southern blotting and RT-PCR, the t(12;21) was identified as a recur-ring chromosomal abnormality in 16~25% of childhood B-lineage ALL. Despite the identification of the fusion partners in the t(12;21), the actual function of the TEL-AML1 and AML1-TEL fusion proteins in promoting malignant transformation is unclear. Whether the TEL-AML1 fusion alone is necessary and sufficient for malignant transformation in ALL and whether TEL inactivation has a role in leukemogenesis is currently unknown. Loss of the CDKN2(p16) gene at 9p21 is a common genetic abnormality in ALL and a variety of other malignancies. Homozygous CDKN2 deketions have been deteced in approximate 15% of B-lineage ALL and 75% of T-lineage ALL cases. The p16 protein functions as an inhibitor of cyclin-dependent kinase 4, and normally acts to stop cell cycle progression. Whether loss of p16 alone is necessary and sufficient for malignant transformation in childhood ALL has not been determined.

We report a case of Ael in a 44-year old woman. The patient s red cells were typed as 0 and her serum had both anti-A and anti-B, but the agglutination strength with Al cell was weaker (2+) than with B cell (4+) in her serum. Additional tests showed that the red cells were not agglutinated by anti-A,B and A antigen on patient s RBC was demonstrated by adsorption-elution test. Her saliva contained H but no A substance, and the ABO genotyping test identified her blood type as AO. We concluded that this was a case of blood type Ael with anti-A.

The fact that therapeutic hypothermia (TH) has lowered intracranial pressure and protected brain in severe traumatic brain injury (TBI) is well known throughout past sources and experimental data. In this paper, the result of TH in TBI needs to be confirmed. The result of North American Brain Injury Study; Hypothermia (NAVIS-H) 1 and 2, Eurotherm3235, Japan trauma society study was reviewed throughout randomized controlled study which performed recently. The prognosis was not confirmed throughout TH in NAVIS-H1; however, there was statistical significance among the group of 45 years or less and below 35 degree in celcius which checked when he or she visited initially. Hence, NAVIS-H2 study was preceded. In patient who had surgically removed hematoma, the effects of TH were proved compared to diffuse brain damage in NAVIS-H2 study. This was found in the result of Japan neurotrauma data bank. Eurotherm study has been doing, which leads to collect many data later on. The TBI of TH makes them better prognosis in patients who had surgically removed hematoma and lowered initial body temperature. Later on, it is considered further study is necessary.

Chemonucleolysis is a significant innovation in the treatment of herniated lumbar disc disease. The prodedure is relatively safe and the results are highly acceptable, but in most studies, the failure rate is 20-25%. Computed tomography was performed from January, 1986 to June, 1987 at the Department of Orthopedic Surgery, Yonsei University on six patients with herniated lumbar discs who did not improve with chemonucleolysis. The results of this study are as follows : 1. The herniated lumbar disc remained unchanged in 4 cases and was reduced in 2 cases. 2. In 2 cases of hernia reduced, the development of a diffuse annular bulging was noted and compression of the dural sac unchanged. 3. Chemonucleolysis was carried out at two levels in 2 cases and the herniated lumbar disc was not changed in these cases. 4. Thickening of the ligament flavum was noted in 1 cases. 5. Computed tomography findings after chemonucleolysis were good correlation with the clinical results in failed cases. In the cases not relieved the symptoms over 3–6 months after chemonucleolysis, it is necessary follow up computed tomography to decide the further treatment.

OBJECTIVES: Chronic pain is one of the most common experiences of humans and a typical psychophysiological disorder. The aim of this study was to measure the psychophysiological responses in chronic pain patients using a biofeedback system, and to compare them with the results from normal healthy subjects. METHODS: Forty two patients with chronic pain (17 males and 25 females, average age 44.67+/-11.10 years) and 42 normal healthy controls (17 males and 25 females, average age 45.17+/-10.46 years) participated in this study. Electromyography (EMG), skin conductance (SC), and skin temperature (ST) were recorded using biofeedback system during the 3 phases (baseline, stress, and recovery) of stress reactivity test, and average values of them were calculated. Difference of values between two groups in each corresponding phase was analyzed with independent t-test, and change of values across phases of stress reactivity test was analyzed with paired t-test (all two-tailed, p<0.05). RESULTS: Compared to normal controls, chronic pain patients had higher value of EMG (baseline : 8.10+/-5.97 micronV vs 4.72+/-1.52 micronV, t=-3.56, p<0.01 ; stress : 11.25+/-6.89 micronV vs 8.49+/-4.78 micronV, t=-2.13, p<0.05 ; recovery : 7.12+/-3.77 micronV vs 4.78+/-1.59 micronV, t= -3.70, p<0.01) and SC (baseline : 1.06+/-1.0 micronS vs 0.42+/-0.29 micronS, t=-4.0. p<0.01 ; stress : 1.87+/-2.05 micronS vs 1.03+/-0.86 micronS, t=-2.47, p<0.05 ; recovery : 1.74+/-1.77 micronS vs 0.64+/-0.59 micronS, t=-3.8, p<0.01) in all the 3 phases. But, skin temperature comparison did not reveal significant differences in all the 3 phases between two groups. CONCLUSION: Psychophysiological responses of chronic pain patients in stress reactivity test were different from those of normal healthy controls. These results suggest that sympathetic nervous system is more activated in chronic pain patients.

Chilaiditis syndrome is very rare clinical condition that interposed of the hepatic flexure of large bowels between the liver and diaphragm. Clinically it is characterized by abdominal pain that becomes increasingly worse during the day and is often accentuated by deep breathing. On radiologic studies, it shows gas within the hepatic flexure interposed between the liver and diaphragm, which is simulating a pneumoperitoneum. A case was admitted at emergency care center of Yeungnam university hospital and we report it.
