To find elements which enable improving Quality of image of chest radiography, we attempted to make comparison between chest radiography used currently with that of the past, and following conclusion was reached: 1) It could be confirmed that a dependance on chest radiography was declining, because proportion of chest radiography against overall radiography decreased. 2) There was a change of kVp to a high voltage in a chest radiography, and use of high kVp became a generalization 3) Exposure time was reduced and exposure dose was curtailed accordingly. 4) Apparatus was mainly comprised of 3-phase rectifier circuit and inverter type. 5) It could be confirmed that frequency of applying additional filters for high kVp radiography was insufficient. 6) There was almost no difference in the condition of exposure between hospitals using film/screen and hospitals using CR. But when CR is used for radiography, it was increase in exposure dose due to increase in tube current and it will be necessary to have continuous study on exposure dose by an increase use of CR in the future.

Summary of Background Data: Myofascial pain syndrome (MPS) is a common painful muscle disorder caused by trigger points occurring in myofascial. MPS is a major cause of chronical pain and is the subject of further clinical examination. Purpose: To uncover effective intramuscular stimulation therapy (IMS), the patients' actively participation stretching exercise and stabilizing around shoulder girdle where trigger point provoking myofascial pain syndrome in usually occurred. Methods: 45 myofascial pain syndrome patients were randomly chosen and divided into 3 groups. The first group (G1) received only IMS therapy, The second group (G2) had both IMS and active stretching exercises administered and the final group (G3) was given IMS therapy and stabilizing exercises. Therapy intervention was given for 3 weeks, 3 times a week and then only stretching exercise for the second group and stabilizing exercise for the third group was given for another 3 weeks. The visual analogue scale was dine before the experiment, 3 weeks after the experiment and 6weeks after the experiment to measure subjective degrees of pain and pressure pain threshold to measure sensitivity improvement of trigger point and functional ability questionnaire to measure daily life performance. Results: There were no significant changes after 3 weeks but after 6 weeks, between G1 and G2 and between G1 and G3 showed significant change of pain, pressure pain threshold and daily life performance. There were significant improvement of the measurement of degrees of pain, pressure pain threshold and improvement of daily life performance at different times for G1 showed change 3 weeks after the experiment, but there were no changes 6 weeks after the experiment. There were significant improvement of the measurement at different times for G2 and G3 showed change 3 weeks after the experiment and 6 weeks after the experiment. Conclusions: IMS therapy proved to be effective in inactivation of trigger points of the myofascial pain syndrome patients and stretching and stabilizing exercises beside it keep remedial value longer by improvement of pain and dysfunction that occurred by the trigger point.

The couple force of the scapular stabilizers for upward rotation that include the upper and lower trapezius, serratus anterior muscles is essential to maintain the stability of shoulder joint. But if there is and imbalance of these muscles, it would occur many problems of shoulder joint. A push-up plus exercise with an unstable support is used in order to increase the muscle activity and stimulate the proprioception of shoulder joint. The purpose of this study was to compare the muscle activity of upper and lower trapezius, serratus anterior muscles and to determine which exercise is more effective when subjects perform push-up plus exercise in the stable support and unstable support. 15 healthy subjects perform push-up plus exercise in the stable support and unstable support. 15 healthy subjects and 15 painful subjects with injury of shoulder joint participated in this study. Surface electromyography data were collected during plus phase of push-up plus exercise. The types of push-up plus exercise were composed of three conditions. Stable type is subjects performed the push-up plus exercise on the fixed support and unstable type 1 is on the sling without shaking and unstable type 2 is on the sling with shaking by tester's manual. The upper and lower trapezius activities of injured group were higher than uninjured group at three measure conditions, but serratus anterior activities were not. The UT/SA ratio of injured group was higher than uninjured group at three measure conditions. The serratus anterior activities were most high at unstable 2 measure in both groups. The UT/SA ratio was most low at unstable 2 measure condition in injured group only. The present result revealed that push-up plus exercise in the unstable support with shaking which took most high serratus anterior activities and most low of UT/SA ratio is optimal cure method that can improve the imbalance of the scapular stabilizer.

Background: We investigated how one pharmacokinetic (PK) model differed in prediction of plasma (C_p) and effect-site concentration (C_eff) using a reproducing simulation of target-controlled infusion (TCI) with another PK model of propofol. Methods: Sixty female patients were randomly assigned to TCI using Marsh PK (Group M) and TCI using Schnider PK (Group S) targeting 6.0 μg/ml of C_p of propofol for induction of anesthesia, and loss of responsiveness (LOR) was evaluated. Total and separate cross-simulation were investigated using the 2 hr TCI data (Marsh TCI and Schnider TCI), and we investigated the reproduced predicted concentrations (MARSH_SCH and SCHNIDER_MAR) using the other model. The correlation of the difference with covariates, and the influence of the PK parameters on the difference of prediction were investigated. Results: Group M had a shorter time to LOR compared to Group S (P < 0.001), but C_eff at LOR was not different between groups. Reproduced simulations showed different time courses of C_p. MARSH_SCH predicted a higher concentration during the early phase, whereas SCHNIDER_MAR was maintained at a higher concentration. Volume and clearance of the central compartment were relevant to the difference of prediction, respectively. Body weight correlated well with differences in prediction between models (R_sqr = 0.9821, P < 0.001). Conclusions: We compared two PK models to determine the different infusion behaviors during TCI, which resulted from the different parameter sets for each PK model.

<P>The risk factors related to hepatitis C virus (HCV) infection showed geographic and temporal differences. We investigated HCV-related risk factors in Korea where intravenous drug use (IVDU) is uncommon. The HCV-related risk factors were investigated in a prospective, multicenter chronic HCV cohort (n = 711) using a standardized questionnaire in four university hospitals. The results were compared with those of 206 patients with chronic liver diseases not related to either of HCV or hepatitis B virus infection (comparison group). The IVDU was found in 3.9% and remote blood transfusion (≥ 20 yr ago) in 18.3% in HCV cohort group, while that in comparison group was in none and 5.3%, respectively. In a multivariate logistic analysis, transfusion in the remote past (odds ratio [OR], 2.99), needle stick injury (OR, 4.72), surgery (OR, 1.89), dental procedures (OR, 2.96), tattooing (OR, 2.07), and multiple sexual partners (2-3 persons; OR, 2.14, ≥ 4 persons; OR, 3.19), were independent risk factors for HCV infection. In conclusion, the major risk factors for HCV infection in Korea are mostly related to conventional or alterative healthcare procedures such as blood transfusion in the remote past, needle stick injury, surgery, dental procedure, and tattooing although multiple sex partners or IVDU plays a minor role.</P>
