As a result of the enlarging pool of unvaccinated children and young adults, there has been an increase in measles in our countries. In these situation, it has been reported that measles associated pneumoinia is easily complicated with fatal respiratory failure, espycially in immunocompromised patients. Herein we report the case of lethal measles pneumonia after allogenic hematopoietic stem cell transplantation in adults proven by autopsy. Recently, one case of measles was encountered in 39-year-old female patients after allogenic bone marrow transplanted case (chronic myelogenous leukemia), who progressed into interstitial pneumonia pattern, despite treatment including antibiotics, immunoglobulin. The patient died of giant cell pneumonia compatible with that of measles which was comfirmed in the section of necropsy lung specimen. (Korean J Infect Dis 33:301∼309, 2001)

Vasculitis is a heterogeneous group of diseases that destroy blood vessel walls by inflammation. Approximately half of vasculitis cases are idiopathic, but sometimes associated with genetic factors, medicines, chronic infection, autoimmune diseases, and malignancies. Although the mechanism remains unclear, vasculitis secondary to malignancy, also known as paraneoplastic vasculitis, has been reported. It is generally associated with hematologic malignancies rather than solid malignancies and commonly presents as leukocytoclastic vasculitis or polyarteritis nodosa. We experienced a case of leukocytoclastic vasculitis in a patient with hepatocellular carcinoma and membranous obstruction of the inferior vena cava. Here, we report this case with a brief review of literature. (J Rheum Dis 2015;22:322-326)

The purpose of this paper is to select 7 male athletes and female athletes of high school, and to compare their active potential differences of trunk muscle according to service motion of tennis. This paper also measures the duration time, and angular velocity of tennis service kinematic variations using Kwon3D(1993) program. When we generalize the change pattern of each variation through normalization process, the results obtained are as follows: 1. In the accumulative distribution rate of trunk muscles in service movement, male athletes show higher muscle active potential in the first service and female athletes show higher muscle active potential in the second service. 2. The ball speed of these athletes after an impact with the racket head is much slower compared with that of the world-famous athletes but of the proper flexsor and extensor of lower limbs, trunk, upper arm, forearm, and racket head are linked properly in sequence, biomechanical efficiency can be obtained in dong powerful service. 3. The angular velocity of wrist joint is much slower compared with that of the world-famous athletes, and this result is thought to be due to improper coordinated movement of the timing and rhythm in upper limb and trunk. 4. The great deviation of angular velocity in elbow joint among male athletes is due to the degree difference of using t he elbow joint. 5. The deviation of angular velocity in shoulder joint is also due to the improper coordinated movement and this keeps athletes from doing powerful service.

The purpose of this paper is to select 7 male athletes and female athletes of high school, and to compare their active potential differences of upper arm muscles according to characteristic of a racket. the results obtained are as follows: 1. In the accumulative distribution rate of racket string tension, 65Ibs is higher in all muscle active potentials except male flexor carpi radialis muscle than 55Ibs or 60Ibs, and this result shows that 65Ibs gives lower efficiency to athletes. 2. In the muscle load rate of racket string tension, 55Ibs shows the lowest active muscle potential and is thought to be better in its efficiency, but 66Ibs shows a little high active potential and is thought not to be good in its efficiency.

The purpose of this study was to examine EMG changes of the body according to method the holding during carrying object. The experiments were conducted with utilizing EMG analyses for five male and five female adults as subjects. The results were as followed. 1. The higher muscle action potential of vertical holding was shown than that of right holding when carrying objects in MMH work in proportion to the weight of the object. The came from the subjects using their brachial muscles much to maintain the angles of their wrist joints and elbow joints for keeping their stable postures while walking. 2. The higher muscle action potential of right holding was shown in right and left elector-muscles of their spines(L1-L2, L4-L5) while carrying in all stages of weights except 25kg objects than that of vertical holding. These results were caused from more use of brachial muscles than elector-muscles of spines in carrying weight objects. So vertical holding is more effective in carrying weight objects at a short distance than right holding.

The purpose of this paper is to select 7 male athletes and female athletes of high school, and this paper also measures the velocity, and angular velocity of tennis service kinematic variations using Kwon3D(1993) program. When we generalize the change pattern of each variation through normalization process, the results obtained are as follows: 1. Female athletes, unlike male athletes, cannot maximize the last velocity of wrist joint at impact. Therefore, this is one of the reasons female athletes do not do powerful service. 2. Elbow joint does not show significant difference between female and male athletes, but in case of shoulder joint, male athletes can swing fully, increase momentum, and obtain biomechanical efficiency. 3. The velocity of these athletes is much slower compared with that of the world-famous athletes but if the proper flexsor and extensor of lower limbs, trunk, upper arm, forearm, and racket head are linked properly in sequence, biomechanical efficiency can be obtained in doing powerful service. 4. Male athletes show more significant difference in enforce phase of shoulder line than female because they can transfer knee joint, flexor, and trunk twist to shoulder joint and gain biomechanical benefit from it.

The diagnostic value of transbronchial lung biopsy(TBLB) through fiberoptic bronchoscope was studied in 61 patients with diffuse or localized lung disease in which routine clinical and laboratory examinations revealed no diagnostic clue. By the technique adequate tissue specimen for diagnosis was obtainable in 28 of 33 patients (78.8 percent) and 25 of 28(89.3 percent) with localized and diffuse lung diseases, respectively. A histological diagnosis was possible in more than 75 percent of the patients with lung cancer proved by various means. On the other hand, in patients with tuberculous lesions, diffuse or localized, the incidence of positive diagnosis was less than a half. The complications among 61 patients underwent the TBLB were pneumothorax in one and hemoptysis in three, which subsided spontaneously. These facts suggest that the TRLB is a relatively safe, and more useful in the diagnosis of cancer of the lung than in inflammatory disease.

When we compare the result of pedar system with that of ground reaction system, the former has more errors in both time and force variation than the latter. Data value measured by pedar system is usually less than that measured by emed system. There must not be the difference between the condition of wearing both shoes and oratoric and that of wearing only shoes, but it is reported that there is difference between them(이성철외 1인). Because the range of using emed system is limited according to its types, the result of ground reaction system is more exact than that of pedar system. Therefore, The choice of experiment equipments fitting for experimental conditions and their practical application are sufficiency taken into consideration. In short, in using emed system, we have to do preliminary experiments and exact material testing. Then, we can use it as experimental equipments and minimize the errors caused by the differences among experimental equipments. In particular, if pedar system should be used in various kinds of sports, it is most desirable to use it in measuring the load amount of each foot part working between shoes and insole.

Although mammalian sperms are cryopreserved for in vitro fertilization a process of cryopreservation decreases the fertility. Acrosome reaction requires depolarization-induced ca^(2+) influx and ca^(2+) releases from the ca^(2+) stores. To examine whether the cellular ca^(2+) mobilization is altered by a sperm cryopreservation we compared cytosolic ca^(2+) signals between fresh and cryopreserved pig sperms using confocal ca^(2+) imaging. The magnitudes of depolarization-induced ca^(2+) increases were significantly smaller in cryopreserved sperms. Exposures to 10 mM caffeine or 5 μM thapsigargin elicited less ca^(2+) increases in the cryopreserved sperms compared to fresh sperms. In addition, progesterone-triggered ca^(2+) rises, that are thought to enhance acrosome reaction, were completely abolished in the cryopreserved sperms. These results suggest that storage and(/or) release of ca^(2+) from the intracellular ca^(2+) stores in pig sperms are significantly impaired by the process of cryopreservation.
