The purpose of this study was to investigate the relevance of body composition and physical fitness to field tests representing the performance of women’s softball players. The subjects of the study were 22 players from women’s softball teams located in “D” city, and they signed a consent form after confirming their willingness to participate voluntarily. The correlation analysis of Pearson was conducted to determine the relevance of field tests(three items: bat speed, throw distance, and base running) to body composition(10 items) and physical fitness(14 items). Results: In field test and body composition, female softball players showed a positive correlation with the forearm circumference in bat speed, and base running with the muscle-related variables(muscle mass and LBM), and the fat-related variables(fat ratio and abdominal fat ratio) showed negative correlation. Results: In field test and body composition, women s softball players showed a positive correlation with the forearm circumference in bat speed, and base running with the muscle-related variables(muscle mass and LBM), and the fat-related variables(fat ratio and abdominal fat ratio) showed negative correlation. In field test and physical fitness, there was a correlation between throw distance and lower limbs muscular endurance(repeating jump), response(standing long jump and vertical jump), agility(side step), and flexibility(trunk forward flexion). Base running showed a significant relevance with muscular strength(grip power), muscular endurance(sit up), response(standing long jump and vertical jump), agility(side step), and flexibility(trunk forward flexion). Body composition and physical fitness were divided into muscle-related and fat-related variables. To sum up, the continuous management of physical composition and the increase in basic and professional physical fitness of female softball players are important factors in improving performance and preventing injury.

Gastric volvulus is an uncommon condition which is difficult to diagnose and treat. It designates abnormal rotation of the stomach along its longitudinal (organoaxial) or transverse (mesenteroaxial) axis. When the rotation exceeds 180˚, gastric obstruction or strangulation may occur. The classical presentation of acute gastric volvulus is the triad of severe epigastric pain, vomiting followed by retching without the ability to vomit, and difficulty or inability to pass a nasogastric tube. Delay in diagnosis and treatment of gastric volvulus can lead to fatal complications such as gastric ischemia, perforation, and hemorrhage. Gastric volvulus is a true emergency which should be treated immediately either surgically or by upper endoscopy. We report a case of an acute incarcerated gastric volvulus due to a left-sided diaphragmatic hernia in an adult male patient, which was treated successfully by operation.

<P>Induction of antigen-specific T cell tolerance would aid treatment of diverse immunological disorders and help prevent allograft rejection and graft versus host disease. In this study, we establish a method of inducing antigen-specific T cell tolerance in situ in diabetic humanized mice and Rhesus monkeys receiving porcine islet xenografts. Antigen-specific T cell tolerance is induced by administration of an antibody ligating a particular epitope on ICAM-1 (intercellular adhesion molecule 1). Antibody-mediated ligation of ICAM-1 on dendritic cells (DCs) led to the arrest of DCs in a semimature stage in vitro and in vivo. Ablation of DCs from mice completely abrogated anti–ICAM-1–induced antigen-specific T cell tolerance. T cell responses to unrelated antigens remained unaffected. In situ induction of DC-mediated T cell tolerance using this method may represent a potent therapeutic tool for preventing graft rejection.</P>

To study the antigenicity of BR92021(Vi polysaccharide typhoid vaccine), active systemic anaphylaxis and passive cutaneous anaphylaxis were tested in guinea pigs. The groups were as follows: group I(low dose, 30 ㎕/kg), group II(high dose, 300 ㎕/kg), group III(300 ㎕/kg plus complete Freund`s adjuvant), group IV(positive control, ovalbumin plus complete Freund`s adjuvant) and group V(saline-treated control). Male Hartley guinea pigs at 7 weeks of age were sensitized subcutaneously with the test article or saline three times per week for three weeks(i.e., total 9 times). For groups III and IV, animals were sensitized subcutaneously with either the test article or ovalbumin plus complete Freund`s adjuvant once per three week for 6 weeks(i.e., total 3 times). Twelve days after the last sensitization, the blood was collected from the sensitized animals for the passive cutaneous anaphylaxis test. In addition, the sensitized animals were subjected to the active systemic anaphylaxis test on fourteen days after the 1st sensitization by an intravenous challenge with either the test article or ovalbumin. In group I, mild(1/5) or moderate(4/5) symptoms of anaphylactic shock were observed. In group II, no sign(1/5), moderate(3/5) and severe(1/5) symptoms were observed. In group III, four animals of 5 revealed moderate signs and one of 5 showed no signs of anaphylactic shock. In group IV, all 5 animals showed severe signs of shock. In group V, one of 5 revealed moderate and four of 5 showed no signs. The necropsy findings related to the active systemic anaphylaxis were observed in most animals of groups I to V. In the passive cutaneous anaphylaxis test, the antiserum was diluted 10- to 5120- fold and was injected intradermally on the clipped back of recipient animals, followed by an intravenous challenge with either the test article or ovalbumin. No animals in groups I, II, III and V showed the positive reaction, whereas all animals in group IV, the positive control, showed the positive reaction at the dilution range of x1280 to x5120. Our results indicate that the test article, BR92021, may have weak antigenic potential in male guinea pigs.
