Many radiopharmaceuticals have been developed and wildy used in the imaging cardiac function. Myocardial perfusion imaging (MPI) is a well established noninvasive method of assessing coronary blood flow and has been widely used in patients diagnosed or suspected with coronary artery diseases. The innovation of radiopharmaceuticals used in the cardiac imaging is one of the most important contributors to the development of nuclear cardiology. Thallium-201 and various technetium-99m agents have been globally used for myocardial perfusion SPEG, and N-13 ammonia (13NH3), rubidium-82 (82Rb), 0-15 water (H2150) for myocardial perfusion PET. As well as the cardiac perfusion studies, new radiopharmaceuticals that visualize fat metabolism or receptors of the sympathetic nervous system have successfully been applied to clinical practice. Useful information can be obtained for diagnosing coronary artery disease, evaluating patients' condition, or assessing therapeutic effects. In this review, we describe the characteristics and clinical usefulness of radiopharmaceuticals used for cardiac SPEG and PET.

Purpose: This study aims to verify the effects of Pilates exercise using the three-dimensional (3D) Schroth breathing technique on scoliosis patients in comparison with the existing Pilates exercise technique, which uses lateral breathing. Methods: The subjects were 16 scoliosis patients who went to S fitness center in Daegu, Korea. They were randomly and equally divided into a Schroth Pilates exercise group (SPEG), who performed Pilates exercise using 3D Schroth breathing, and a Pilates exercise group (PEG) who performed Pilates exercise using lateral breathing. The subjects conducted the Pilates exercise three times per week for 12 weeks. Changes in their Cobb's angle, angle of trunk rotation, and chest expansion ability were measured before and after the exercise. Results: Both groups experienced significant improvement in their Cobb's angle, angle of trunk rotation, and chest expansion ability after the exercise (p<0.05). Between-group comparison after the exercise showed that SPEG's improvement in Cobb's angle, angle of trunk rotation, and chest expansion ability were more significant than those of the PEG (p<0.05). Conclusion: This study verified that Pilates exercise using 3D Schroth breathing was more effective in improving scoliosis patients'physical condition than existing Pilates exercise. The researcher anticipates that the 3D Schroth breathing technique will be effectively utilized in other diverse intervention exercises besides Pilates exercise.

Background: The purpose of this study is to examine the effect of push-up plus exercise on the changes in the thickness of the trapezius trapezius, serratus anterior and pectoralis major muscles involved in shoulder stability in various support surfaces. Design: Randomized controlled trial. Methods: The thickness change of the shoulder stabilizing muscle was measured using an ultrasound device. Corresponding t-test was performed to confirm the change within the group before the experiment and after 5 weeks. And one-way ANOVA was used to confirm the change between groups after 5 weeks. As a post hoc test, the least significant difference test was performed, and the significance level was set to a=0.05. Results: Changes in the thickness of the trapezius muscle within the group were significantly different between UPEG and SPEG after 5 weeks (p<0.05), and there was a significant difference between groups after 5 weeks (p<0.05). Changes in the thickness of the serratus anterior and pectoralis major muscle within the group were significantly different after 5 weeks in PEG, UPEG and SPEG (p<0.05), and the changes between the groups were significantly different in the serratus anterior muscle after 5 weeks (p<0.05). Conclusion: From the results of this study, it was found that the push-up exercise on an unstable support surface was effective for strengthening the trapezius upper and serratus anterior. This study intends to suggest the possibility of application as basic data for a push-up plus exercise program in clinical practice.

Reverse redistribution is frequently observed after revascularization in acute myocardial infarction, and usually regarded as a predictor of viable myocardium on stress/rest and 2- to 4-hour redistribution $^{201}Tl$ SPECT. However, there is not enough report of reverse redistribution in case of 24-hour delayed SPECT, which is commonly used for viability assessment. In this report, a case of reverse redistribution on rest and 24-hour delayed $^{201}Tl$ SPECT is reported with use of automatic segmental quantitative analysis. The myocardium of reverse redistribution was dysfunctional on gated SPECT, and diagnosed as non-viable on $^{18}F-FDG$ PET.

The taxonomic status and phylogenetic relationship of Opuntia monacantha Haw. f. jejuensis J. K. Kim ex Y. S. Yang (Jejubaiknyuncho), which is native to southern coast of Jeju Island, Korea was analyzed using DNA markers obtained from Korean Opuntia. Opuntia stricta Haw., O. humifusa Raf., and O. humifusa Raf. f. jeollaensis E. J. Kim and S. S. Whang, native or cultivated in Korea, have no stripes on the back of tepals and have a purple pulp, whereas O. monacantha f. jejuensis has purple stripes on the back of tepals and a greenish-yellow pulp color. Opuntia monacantha has purple stripes on both the front and back of its tepals, whereas stripes appear only on the back of tepals of O. monacantha f. jejuensis. Opuntia monacantha f. jejuensis was assigned to Elatae series in phylogenetic analysis and was found to be more closely related to O. monacantha subsp. arechavaletae (Speg.) Guiggi, compared with O. monacantha at a molecular level. Based on its phylogenetic and morphological differences from O. monacantha and O. monacantha subsp. arechavaletae, which are native or have been cultivated in Jeju areas, O. monacantha f. jejuensis was named as a new forma in this study.

This study was carried out to know pathogenicity of the pathogen isolated in several location of Korea and penetration mechanism of the Pseudocercospora vitis ($(L\acute{e}v)$.) Speg. Inoculation tests at room temperature were performed on both sides of leaves with different isolates of the fungus. The typical symptoms appeared on the abaxial leaf surface, but no symptom was observed on the adaxial leaf surface with all isolates. The average incubation period was nine days, since all symptoms appeared from 8 to 10 days after inoculation. In order to know the mechanism of invasion of P. vitis to grapevine, the behavior of penetration hyphae through stomata were compared in two cultivars having different level of resistance. In order to know the mechanism of resistance of grape vine to P.vitis, two cultivars having different level of resistance were compared by counting the numbers and measuring size of the stomata per leaf. In a susceptible cultivar Campbell Early, the number of stomata was more than that of a resistance cultivar 'Kyoho'. In a susceptible cultivar 'Campbell Early', the fungus entered readily into stomata after inoculation. However, in a resistant cultivar 'Kyoho', the fungus seemed to pass over or surrounded only the guard cells. In comparison of height of guard cells of stomata between the two cultivars, significant differences were observed by scanning electron microscopy and light microscopy. The height of guard cells of 'Campbell Early' showed a little higher than those of 'Kyoho' known to be resistant to the fungus.
