Purpose: Various hemostatic agents have been introduced in therapy as postoperative bleeding is a poor prognostic factor for postoperative outcomes. These products can be divided into those that directly promote the hemostatic cascade and those that physically form a barrier by absorbing blood. The latter, powder-type hemostatic agents have the advantages of being inexpensive and more absorbable with less foreign body reactions (FBRs) and are applicable to a relatively wide area. This study was conducted to verify the safety and efficacy of a newly invented polysaccharide product (OOZFIX, Theracion Biomedical), which improves blood absorption and hemostatic effects. Methods: Two separate animal experiments were performed. The first evaluated FBRs histologically at 3 days, 2 weeks, and 4 weeks, after implantation of OOZFIX in rats, and the second compared hemostatic performance of OOZFIX and Arista AH (Bard) in the porcine liver punch biopsy model. Results: We found minimal FBRs in the 3-day group and no reactions in both the 2-week and 4-week groups after implantation of hemostatic agents. The time to hemostasis of OOZFIX was not significantly different from that of Arista AH (median [interquartile range]: 9 [6–10] minutes vs. 8 [6–10] minutes, respectively; P = 0.522). When comparing the serial bleeding grade tendency, there was no statistical difference between OOZFIX and Arista AH (P = 0.656). Conclusion: OOZFIX caused a minimal FBR that disappeared within 2 weeks in vivo, and its hemostatic performance was comparable with that of an existing agent, Arista AH. Further clinical studies are required in the future.

The purpose of this study was to analyze the effects of aerobic exercise on abdominal obesity, cardiopulmonary function and serum insulin in obese middle school girls participated in aerobic exercise for 20 weeks. The conclusions are as follows ; 1. Total body fat, percent body fat, body mass index, waist circumference and waist-hip ratio were significantly decreased, but lean body mass was significantly increased in the changes of body composition factors. 2. Systolic blood pressure, diastolic blood pressure were significantly decreased, but maximal oxygen consumption was significantly increased in the changes of cardiopulmonary function factors. 3. Total cholesterol, triglyceride, low-density lipoprotein cholesterol and insulin were significantly decreased, but high-density lipoprotein cholesterol was significantly increased in the changes of serum lipid and insulin factors. In conclusions, aerobic exercise may be very effective to decrease the obesity and geriatric diseases.

Vibrio cholerae is mainly known to cause gastrointestinal infection after seawater exposure or raw seafood intake. It is rarely reported to cause cellulitis or sepsis, but threre has been no known case after acupuncture. Herein, We report a 56-year-old cirrhotic patient of non-O1, non-O139 Vibrio cholerae septicemia caused by cellulitis of both lower extremities after acupuncture.

The use of restriction fragment length polymorphisms (RFLPs) has been proposed for the construction of a human genetic linkage map and also become a powerful tool in human population genetics. Human Y-chromosome which is haploid and paternally inherited is valuable for investigating male-mediated gene flow and for complement maternally based studies of mtDNA. We have studied 166 samples from 4 kinds of family origin names such as Kyungju Kim, Kimhae Kim, Chunju Lee and Milyang Park based on the 49aTaq 1 polymorphisms, and a total of 25 haplotypes were observed. The B, F, and I bands is observed in all haplotypes and haplotype showing A3, B, D2, D3, F, and I bands is common haplotype except for Chunju Lee. The result obtained are summarized as follows.

The rearrangement of c-ros oncogene 1 (ROS1) has been recently identified as an important molecular target in non small cell lung cancer (NSCLC). ROS1 rearrangement and epidermal growth factor receptor (EGFR) mutation were mutually exclusive each other in previous studies, and the clinical implication of co-existence of the two genetic alterations has not been determined. We report a case of 46-year-old female never-smoker NSCLC patient whose tumor harbored ROS1 rearrangement and EGFR mutation concomitantly. She had undergone curative surgery for stage IIIA NSCLC, and the recurrence in left pleura and brain occurred at 2 years after the surgery. She received several lines of chemotherapy including docetaxel plus carboplatin, erlotinib, pemetrexed, and gemcitabine. Erlotinib therapy showed a favorable treatment response with progression-free survival of 9.5 months and partial response of tumor on radiologic evaluations. This case represents a successful erlotinib treatment in a NSCLC patient with concurrent ROS1 rearrangement and EGFR mutation.

<P>Self-assembly of inter- and intraphases between the ionomer membrane and mechanical reinforcements in reinforced polymeric composite membranes is of great interest in both physics and chemistry, particularly for proton exchange membrane fuel cell (PEMFC) application. One of the greatest challenges is to obtain an optimally structured polytetrafluoroethylene (PTFE)-reinforced perfluorosulfonic acid (PFSA) composite membrane <I>via</I> solution processing. For high- performance and durable PEMFC applications, the self-assembly of interphases of the ionomers/reinforcements and intraphases of the ionomers in the composite PEM needs to be carefully tailored. Here, we show that post-assembly modification of a PTFE/PFSA composite membrane using a spin-drying method can significantly improve fuel cell performance and reliability. The forced assembly of PFSA ionomers during spinning results in greater infiltration yields into the porous PTFE media. In this way, spin-drying post-treatment results in lower gas crossover and improved mechanical durability. This process also yields larger regions of ionic clusters, which facilitate proton conduction at low relative humidity, affording higher fuel cell currents and greater efficiency.</P>
