Genes encoding sequence-specific DNA binding proteins have been isolated by screening cDNA libraries constructed in rgt11 expression vector with recognition site DNAs. We isolated a rgt11 recombinant human cDNA clone, designated to C2, using a DNA probe consisted of heptamer of the perfect palindrome (PP; GGGGATTCCCC) of enhancer A (Enh A) of HLA dass I promoter. Sequencing analysis showed that this clone contained a partial cDNA homologous to NF-kB2. Lysogenic E. coli containing the C2 was generated and crude cell extract was prepared. Immunoblot using anti-B-galactosidase antibody showed that this lysogenic E. coli expressed B-galactosidase fusion protein. Electrophoretic mobility shift assay (EMSA) and DNase I footprinting assay were done using crude cell extract and their patterns were compared with nuclear protein extracted from an EBV transformed B lymphoblastoid cell line (BLCL). EMSA showed that crude cell extract prepared from E. coli lysogen speci5cally bound to the PP of Enh A region of HLA class I gene. DNase I footprinting assay showed that the binding sequence of this recombinant B-galactosidase fusion protein was identical to that of nuclear protein extracted from a BLCL. Our data indicate that a Agt11 recombinant cDNA clone was isolated from a human cDNA library using the PP of Enh A of the HLA class I promoter and this clone encoded a B-galactosidase fusion protein capable of binding to the PP and belongs to a NF-xB subunit.

BACKGROUND: Endobroncheal intubation or extubation may occur accidentally when the patient's neck is flexed or extended even in the appropriate endotracheal intubation. The purpose of this study is to examine the effect of fixation or unfixation of the endotracheal tube at the teeth level on the displacement of its distal end when the patient's neck is extended or flexed. METHODS: This study was conducted in 37 patients who underwent endotracheal general anesthesia. The patients with the evidence of pathology in head, neck and chest were excluded from the study. Individual patient's displacement in endotracheal tube tip compared unfixed cases with fixed cases when the change of neck position. The moved distance was measured by fiberoptic bronchoscope. The data were statistically analyzed by Student's paired t-test. RESULTS: The endotracheal tube moved away from the carina when the patient's neck was extended, while it moved toward the carina when flexed in all cases. When the patient's neck was extended the average distance displaced 1.2 0.7 cm in fixed cases and 1.1 0.9 cm in unfixed cases. when the neck was flexed, they were 1.2 0.5 cm and 1.0 0.8 cm respectively. There were not statistically significant between the fixed and the unfixed cases. CONCLUSIONS: It is concluded that the displacement of the endotracheal tube is not related to its fixation or unfixation at the teeth level and therefore, unfixation does not provide any benefits in terms of the displacement of the distal end of the tube in adult trachea.

Subcutaneous emphysema is a complication of the pneumoperitoneum necessary to perform laparoscopy and will be seen more often as laparoscopic techniques are applied to a growing number of intraabdominal procedures. We report a case of subcutaneous emphysema and hypercarbia without pneumothorax or pneumomediastinum during laparoscopic cholecystectomy, which was treated by multiple puncture with 18G needle on emphysematous site. The suspected cause is inadvertent subcutaneous insufflation of carbon dioxide through the trocar sites by increased intra-abdominal pressure for the establishment of pneumoperitoneum. Immediate recognition, evaluation, and treatment of subcutaneous emphysema is necessary since this can be life-threatening complication.

There are several methods for diagnosis of leprosy, including AFB stain, the measurement of PGL-1 (phenolic glycolipid - 1) antigen titer, and DNA-PCR. In this study, we have used the DNA-PCR amplifying the RLEP repetitive sequence. Our result showed that the RLEP primer offered the more sensitive detection and identification of M. leprae DNA in clinical specimens, compared with the other primer, for example, 18-kDa antigen gene. To screen the resistant M. leprae strain of MDT (Multi-Drug Therapy), we have used the TD (Touch-Down) PCR. We arranged and amplified sequences of the genes, folP, rpoB, gyr, 23S rRNA, in M. leprae involved in MDT-resistance, and could obtain the PCR product each gene, simultaneously. This method, based on annealing temperature, was useful to the detection for diagnosis and the screen of MDT-resistant strain of M. leprae, rapidly. Thus, we suggest that the RLEP primer and TD-PCR method are effective in assessing the diagnosis of leprosy and the identification of drug-resistant M. leprae.

A 19-year-old man had a good neurologic recovery from a severe hypothermia(19 degrees C) and a prolonged coma following active infernal rewarming. From inhaling hydrocarbons, he was left unconscious on the cold floor for 24 hours. As soon as the patient was brought into the emergency medical center, he was early evaluated arid treated aggressively. ECG showed Osborn(J) wave on all leads. The temperature o( patient was increased by 2-3 degrees C per hour through active external rewarming (by heating blankets and warm bag) and active infernal rewarming (by airway rewarming, warmed IV fluids, gastrointestinal tract irrigation, and bladder irrigation). The temperature reached 36 degrees C after 6 hours. Active infernal rewarming provides rapid core rewarming with the additional benefit of circulatory support during the period of cardiac instability.

BACKGROUND: The purpose of this prospective study is to define the effect of cardiopulmonary bypass (CPB) on the concentration of thyroid hormones and metabolites. METHODS: Blood samples were obtained from 15 patients undergoing open heart surgery at 1) pre-induction, 2) after heparinization, 3) during CPB, 4) 2 hours after CPB, 5) 24 hours after CPB and 6) 48 hours after CPB. Thyroid stimulating hormone, albumin, thyroxine (T4), free thyroxine (FT4), triiodothyronine (T3), free triiodothyronine (FT3) and reverse T3 (T3) were measured. RESULTS: Concentration of T3 significantly decreased after infusion of heparin and maintained at the decreased level until postbypass 24 hours. Concentration of FT3 significantly increased after heparin administration but maintained at a control level during CPB and decreased after postbypass 24 , 48 hours (p<0.05). Reverse T3 increased at 24 and 48 hours after CPB (p<0.05). Thyroxine decreased during CPB and return to control level after CPB. Free thyroxine did not change significantly. Thyroid stimulating hormone was significantly depressed at 24 hours after CPB (p<0.05). CONCLUSIONS: This result suggest that the thyroid function is depressed until 48 hours after CPB and it seems to be associated with abnormal metabolism of thyroid hormones.

Renal tuberculosis is one of the most frequent disease in the urological field of Korea for a long period of time. A clinical observation of renal tuberculosis was made on the 50 cases admitted to the Department of Urology, Korea University Hospital from January 1968 to December 1975. The results summarized as follows: 1. The ratio of number of renal tuberculosis cases admitted against total number of urological inpatients is decreasing significantly every years. 2. 31 cases out of 50, belonged to the age group of 21 to 40. 3. Both kidneys were affected in 13 cases, while 21 cases in right side only and 16 cases in left kidney. 4. The important subjective symptoms were as follows: frequency in 54%, painful urination in 40%, flank pain in 40 %, gross hematuria in 38% and asymptomatic in 1 case. 5. 32% of the cases visited to the hospital within 6 months after onset of the symptoms. 6. 56% of the cases were associated with pulmonary tuberculosis. 7. Tuberculous epididymitis were complicated in 3 cases, bone tuberculosis in 1 case and squamous cell carcinoma of the bladder was found in 1 case. 8. Increased ESR were found in 42 cases and 43 cases were within normal range of BUN. 9. Urinary findings revealed proteinuria in 94%, hematuria in 74% and pyuria in 76%. Urine AFB was found in 26 cases (52%). 10. 18 cases of AFB culture was done with drug sensitivity test, which showed that INH was the most sensitive drug, but PAS and streptomycine were sensitive in high concentration of the drugs only. 11. On the urogram, non-visualization of the kidney was found in 20 cases and delayed visualization in 15 cases while abnormal ureteral findings noted in 18 cases. 12. Nephrectomy was performed in 23 cases out of 31 operated cases and nephrostomy was done in 7 cases. 13. Histopathological findings of 23 nephrectomized kidneys disclosed parenchymal tuberculous nodules in all cases and severely atrophic changes in 3 cases.

Induction of general anesthesia with tracheal intubation has several advantages but also causes some cardiovascular side effects. Several approaches have been tried to reduce these side effects. As an attempt to reduce elevated blood pressure and increased heart rate during tracheal intubation, we used thiopental 3 mg/kg with Thalamonal 0.05 mg/kg (experimental group II, 30 cases) as an induction of general anesthesia inatead of the conventional use of thiopental 6 mg/kg(control group I, 30 caaes). The results are as follows:1. Blood pressure and heart rate changes between the 2 gruops at postintubation 30 sec. were statistically significant; 194+/-24 torr, 111+/-15/min. in control gruop and 166+/-29 torr (p<0.01), 102+/-14/min. (p<0.05) in experimental group. 2. There were no significant changes in blood pressure and heart rate at pre-intubation and post-extubation period. 3. The incidence of tachycardia and arrhythmia were more frequent in the control group, while hypotension and severe respiratory depression in experimental group.
