Differences in systolic time intervals(STI's) attributable to the types of mechanocardiographs used for their determinations were studied in a total of 341 healthy adult males. The STI's were measured from mechanocardiograms consisting of simultaneously rocorded electrocardiograms, phonocardiograms and carotid arterial pulse tracings obtained by each of three different types of mechanocardiographs in 125, 56 and 160 subjects, respectively. The study revealed that there were slight to considerabe differences among the three groups in the correlation coefficients between the individual STI's and heart rate. Thus, regression equations using heart rate as variables, for those STI's which were significantly correlated with heart rate, differed slightly to considerably among these groups. In addition, the mean values of those STI's and their derivatives, which showed no significant correlation with heart rate, were also silghtly or significantly different among the three groups. These findings suggest that if STI's obtained from patients are to be adequately evaluated at all, each laboratory must define its own normal standards worked out by using its own methods of recording and analysis of the mechanocardiogram, and cannot rely on those proposed by others.

There are many procedures described for the treatment of acromioclavicular seperation but there are still controversies concerning the best management of these injuries. Thirteen cases were operated on by technique of modified Phemister method and four cases by Bosworth method, Dept. of Orthopedic Surgery, Chonbuk National University Hospital from January 1980 to December 1984. The following results were obtained. The following results were obtained. 1. This injuries is more prevalent in male (76.4%) with peak incidence in the second, third and fourth decades(76.4%). 2. The most common causes of the injuries were traffic accidents and followed by falling from the height. 3. Fifteen patients were grade 3 by Allmans classification. 4. Operative method consists of modified Phemister method (76.4%) and Bosworth method (23.6%). 5. The operative procedures in Type 2 and Type 3 are good treatment of acromioclavicular seperation.

BACKGROUND: Induced hypotension reduces blood loss in the surgical field and provides better visibility, but may produce an ischemic damage on liver. The purpose of this study is to evaluate postoperative liver function according to the degree of induced hypotension in spine surgery. METHODS: Sixty patients were classified into three groups. In group 1 (n=20) undergoing simple laminectomy, the systolic blood pressure (SBP) was maintained at 120 to 100 mmHg with controlling the concentration of enflurane. Hydralazine and/or esmolol were given to maintain the SBP at 100 to 80 mmHg in group 2 (n=20) and 80 to 60 mmHg in group 3 (n=20) as needed. Preoperative and postoperative 1, 3, 5, 7 day's serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvate transaminase (SGPT) and alkaline phosphatase (ALP) were evaluated. RESULTS: In group 1, postoperative SGOT levels were increased significantly on postoperative 1, 3, 5, 7 day and postoperative SGPT levels were increased significantly on postoperative 7 day only. In group 2, postoperative SGOT levels were increased significantly on postoperative 1, 3, 5, 7 day and there was no significant difference between preoperative and postoperative SGPT levels. In group 3, postoperative SGOT levels were increased significantly on postoperative 1, 3 day and postoperative SGPT levels were increased significantly on postoperative 3, 5, 7 day. There was no significant difference among three groups in SGOT and SGPT levels. Postoperative ALP levels were decreased on postoperative 1, 3, 5, 7 day in all groups and there was no significant difference among three groups except a significant difference between group 1 and 3 on postoperative 1, 3 day in ALP levels. CONCLUSIONS: These results suggest that severe reduction in SBP at 80 to 60 mmHg by hydralazine and/or esmolol under general anestheia with enflurane can not exclude the possibility of liver damage.

Molecular epidemiology has been initiated for the confirmation of transmission link among tuberculosis patients. IS6110 restriction fragment length polymorphisms (RFLP) technique has been used as an excellent tool to discriminate Mycobacterium tuberculosis isolates, especially in tuberculosis (TB) outbreak in the population. IS6110 RFLP has the most discriminatory power for the M. tuberculosis isolates with high copy number of IS6110 like Korean isolates. Spoligotyping using spacers of direct repeat is useful to distinguish Beijing strains which are found widely in Eastern Asia, from non-Beijing strains. It is known that Beijing strains are more virulent, apt to be drug resistant than non-Beijing strains. Strain typing techniques of Mycobacterium tuberculosis has lead to the development of phylogenetic classification. Variable number tandem repeat (VNTR) of M. tuberculosis is another good target for strain typing. The technique using VNTR is rising as an alternative tool to overcome disadvantages of IS6110 RFLP which is time consuming in the sense that it takes longer time to process from the culture positive bacilli, and has the intrinsic difficulties in objectification of the results. The combination of many VNTR loci enhances discriminatory power to become equal to that of IS6110 RFLP. On the other hand, the optimal VNTR combination differs from one country to another due to different dominant clade. Large sequence polymorphisms (LSP) and single nucleotide polymorphisms (SNP) are important tools for the classification of the phylogeny of M. tuberculosis complex. Many previous reports indicate that the depending upon the type of strains, the ways of transmission of disease, the way to get infected with disease and the development of drug resistance conditions are variable. Therefore, the molecular epidemiology of M. tuberculosis has become more important for tuberculosis control in the world. It will be possible to set up tuberculosis-tailored policy after the characterization of M. tuberculosis by molecular epidemiologically.

With the recent introduction and development of the detachable balloon system, it has become the treatment of choice in the management of carotid cavernous fistulas(CCFs). But, since most delivery systems for embolization of CCF mainly depend on flow guidance for balloon delivery, in cases of small fistula, pseudoaneurysm and arterialized venous collaterals, failure of balloon embolization can occur. To overcome these limitations, the authors designed and used a new versatile, steerable, and flow-guided detachable balloon system by using a Tracker catheter system with silicone or latex balloons. Using this maneuver, we could get successful fistula occlusion in 7 out of 8 patients(silicone balloon). But in one case, we had to occlude the internal carotid artery at the fistula site, proximal and distal cervical portions of the internal carotid artery. This balloon delivery system proved to provide high selectivity for fistula and relatively ease of handing.
