The Actinomyces species are normal flora of oral cavity and upper intestine characterized as gram-positive, non-spore-forming anaerobic or mjcroaerophilic rods. Actinomycosis is a chronic suppurative and granulomatous disease characterized by abscess, sinus, abundant granulation and mass. The appendix is the commonly involved site among abdominal actinomycosis. Abdominal actinomycosis is often difficult to diagnose before operation because of no reliable clinical features and infrequency of the disease. We report two cases of abdominal actinomycosis which were manifested as acute appendicitis. Those were detected Incidentally tv the pathologist after routine appendectomy. Both patients were successfully treated with appendectomy followed by proper antibiotics use.

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

Bortezomib is the first clinically available proteasome inhibitor that is clinically effective in the treatment of multiple myeloma. A proteasome inhibitor acts through multiple mechanisms to arrest tumor growth, tumor spread, and angiogenesis. The main adverse effects of bortezomib are gastrointestinal symptoms, cytopenia, fatigue, and peripheral neuropathy. To date, severe paralytic ileus has not been reported as a toxic effect of bortezomib treatment in multiple myeloma. Bortezomib is a novel agent that has only been used clinically for 30 months, so a need exists to further evaluate its toxicity. We report a case of grade Ⅲ (NCI CTCAE v3.0) or grade Ⅳ(SWOG toxicity criteria) paralytic ileus in a 65-year-old man with relapsed multiple myeloma who underwent one cycle of single-agent bortezomib treatment scheduled in a 21-day cycle (1.3 mg/㎥ as a single i.v. bolus on days 1, 4, 8, and 11).

Splenic marginal zone lymphoma is very rare B-cell lymphoma, characterized by an indolent clinical course. Clinical features are moderate-to severe splenomegaly, absolute lymphocytosis, and bone marrow intrasinusoidal infiltration of lymphocyte. We report the case of a 37-year-old male with SMZL. He complained of LUQ pain, who had a massive splenomegaly and moderate lymphocytosis in peripheral blood. Immunophenotyping findings and morphologic findings were consistent with SMZL. He underwent splenectomy and received chemotherapy with cyclophosphamide for eight months. Now, one year later after surgery he has a nearly normal blood count with no treatment.

The purpose of this study was to analysis the muscle moment in tennis serve. Seven Korean national tennis players were filmed using the Direct Linear Transformation method of three-dimensional cinematography. Abtained coordinate data and the model developed using Cardan angles and Euler's Equation were used to calculate the joint moments exerted on the serving arm segments(the upper arm, the lower arm, the hand). The Cardan angles between the two embedded axes of the two connected segments was used to define the anatomical motions of the segments. The anatomical motions and the joint moments of the segments were analyzed to determine the net muscle activity pattern. The conclusion of this study was the maximum liner velocity accord in the following pattern first at the shoulder joint, next at the elbow joint, then at the wrist joint, and last at the racket head. this result shows that the tennis serve has been done in a proximal to distal pattern and this is an important characteristic of the tennis serve. The joint forces and moments indicated that the eccentric activities of the antagonists were primarily responsible for this serve movement. Such antagonists activities were more apperent on the lower arm than that on the upper arm. So the coaches have to emphasize the movement of the prime proximal segment, trunk, which activate this serve movement and the control of the remained segments can be achieved naturally by the repeated training.

Y. W. JIN, J. M. SHIN. Biomechanical Comparative Analysis of Two Goal-Kick Motion in Soccer. Korean Journal of Sport Biomechanics, Vol. 15, No. 1, pp. 29-44, 2005. The purpose of this study is to reveal the effects of two different kicks, the drop kick and the punt kick, into the kicking motion, through the kinetic comparative analysis of the kicking motion, which is conducted when one kicks a soccer goal. To grasp kinetic changing factors, which is performed by individual's each body segment, I connected kicking motions, which were analyzed by a two dimension co-ordination, into the personal computer to concrete the digits of it and smoothed by 10Hz. Using the smoothed data, I found a needed kinematical data by inputting an analytical program into the computer. The result of comparative analysis of two kicking motions can be summarized as below. 1. There was not a big difference between the time of the loading phase and the time of the swing phase, which can affect the exact impact and the angle of balls aviation direction. 2. The two kicks were not affected the timing and the velocity of the kicking leg's segment. 3. In the goal kick motion, the maximum velocity timing of the kicking leg's lower segment showed the following orders: the thigh(-0.06sec), the lower leg(-0.05sec), the foot(-0.018sec) in the drop kick, and the thigh(-0.06sec), the lower leg(-0.05sec), the foot(-0.015sec) in the punt kick. It showed that whipping motion increases the velocity of the foot at the time of impact. 4. At the time of impact, there was not a significant difference in the supporting leg's knee and ankle. When one does the punt kick, the subject spreads out his hip joint more at the time of impact. 5. When the impact performed, kicking leg's every segment was similar. Because the height of the ball is higher in the punt kick than in the drop kick, the subject has to stretch the knees more when he kicks a ball, so there is a significant affect on the angle and the distance of the ball's flying. 6. When one performs the drop kick, the stride is 0.02m shorter than the punt kick, and the ratio of height of the drop kick is 0.05 smaller than the punt kick. This difference greatly affects the center of the ball, the supporting leg's location, and the location of the center of gravity with the center of the ball at the time of impact. 7. Right before the moment of the impact, the center of gravity was located from the center of the ball, the height of the drop kick was 0.67m ratio of height was 0.37, and the height of the punt kick was 0.65m ratio of height was 0.36. The drop kick was located more to the back 0.21m ratio of height was 0.12, the punt kick was located more to the back 0.28m ratio of height was 0.16. 8. There was not a significant difference in the absolute angle of incidence and the maximum distance, but the absolute velocity of incidence showed a significant difference. This difference is caused from that whether players have the time to perform of not; the drop kick is used when the players have time to perform, and punt kick is used when the players launch a shifting attack. 9. The surface reaction force of the supporting leg had some relation with the approaching angle. Vertical reaction force (Fz) showed some differences in the two movements(p<0.05). The maximum force of the right and left surface reaction force (Fx) didn't have much differences (p<0.05), but it showed the tendency that the maximum force occurs before the peak force of the front and back surface (Fy) occurs.

The purpose of this study is, fast, to compare heel angles through analyzing reaction force from the ground and also by analyzing images using force platforms through the basic motions of walking and running during a soccer game. Secondly, the purpose of this study is to clarify how each type of soccer shoes effects soccer players, which will provide scientific data to coaches and players, to further prevent injuries and to improve each players capacity. The results of this study can be summarized after testing the two types of soccer shoes with comparative transforming heel angles and also with a pressure distribution in both walking and ruining. The comparison of the very first decelerating force and accelerating force at walking found distinctive factors in the statistical data(p<.05). In the motion of stepping, the role of both offensive shoes and defensive shoes deceleration percussion force, showed distinctive factors in the statistical data(t=3.671). The comparison of accelerating shock power showed distinctive factors in the statistical data(p<.05). In comparing the shock power of deceleration(-11.25N·s), the result showed a statistically significant difference(t=2.947) in the two soccer shoes(-11.25N·s, -9.47N·s) at running(2.1m/sec). In the maximum braking force for back and forth direction, there was a statistically significant difference between the two soccer shoes(p<.05) at running(6.2m/sec). In a fast moving situation, there was a considerable difference between the soccer shoes for attacking. When a player's foot first touched the ground, the average difference of in/eversion was between 1 and 3 degrees for the two soccer shoes. In regards to maximum inversion and eversion of foot, maximum tibial rotation, and maximum and total movement of foot, the condition of barefoot and the two soccer shoes showed a small difference from 1 to 3.5 degrees and the difference among the subjects of study wasn't constant. In regards to maximum velocity of inversion and eversion running in one's bare feet showed much lower inversion velocity in comparison to putting on two types of soccer shoes and comparison of the average. Among some of the subjects, after putting on the two types of soccer shoes exceeded 100。/s in maximum velocity of eversion.
