The civilization has given us a great comfort and convenience but also it has been threatening our life at the same time. Recently among these causes of death the traffic accident is the most dangerous thing to threat our life. Most traffic accidents happen on the road but are increasing on the sea and river recently. Accordingly this paper presents an accident example for a boat collision accident which was anlalyzed from the evidences drawn by forensic medical and scientific methods for a passenger death accident by a collision between two boats. The forensic medical accident interpretation was made up by autopsy and drug toxicology inspection. A person who has met an unnatural death at the accident time was drunken condition. The cause of death was judged by the multiple viscera injury, and presumed to be killed by applying an high external force. In order to perform a forensic scientific analysis, we investigated the passenger's life jacket that a person killed in the accident was wearing and also investigated the external appearance of two boats which have 150h.p and 130h.p. Through comparing the position of two boats with the direction of impact on the surface of the water, we could assume that the 130h.p boat impacted the tail on the right side of 150h.p boat with constant acceleration or constant velocity.

Carbon monoxide(CO) is a colorless, odorless, tasteless, and non-irritating gas whose relative density is a little less than that of air. The most common sources of CO in deaths are fires, automobile exhaust, defective heaters, and incomplete combustion of burning products, such as charcoal briquets. CO is produced whenever organic materials are burned with inadequate supply of oxygen necessary to produce complete combustion. The CO poisoning is one of the most common causes of death in developing and underdeveloped countries. Almost fatal CO poisoning cases, mostly accidental or suicidal deaths occur in enclosed or restricted place nearby fuel-burning heating appliances. However, this case occurred in very unusual place away from the heating appliances due to faulty chimney duct. Because of a peculiar place, it is difficult to imagine the cause of death as a CO poisoning. Deaths from CO inhalation can occur if the individual is in proximity to a rich source of CO for a prolonged time. Therefore, even though men dies away from the heating appliance, it is necessary to bear in mind the possibility of CO poisoning.

In our ongoing search for new secondary metabolites from fungi, a basidiomycete fungus Irpex consors was selected for mycochemical investigation, and three new zwitterionic alkaloids (1-3) and five known compounds (4-8) were isolated from the culture broth (16 l) of I. consors. The culture filtrate was fractionated by a series of column chromatography including Diaion HP-20, silica gel, and Sephadex LH-20, Sep-Pak C18 cartridge, medium pressure liquid chromatography (MPLC), and high pressure liquid chromatography (HPLC) to yield eight compounds (1-8). The structures of the isolated compounds were elucidated by the interpretation of nuclear magnetic resonance (NMR) spectra and high-resolution mass spectrometry (HR-MS). Their antioxidant and antibacterial activities were examined. The zwitterionic structures of three new sesquiterpene alkaloids (1-3) were determined together with five known compounds identified as stereumamide E (4), stereumamide G (5), stereumamide H (6), stereumamide D (7), and sterostrein H (8). This is the first report of the zwitterionic alkaloids in the culture broth of I. consors. Three new zwitterionic alkaloids were named as consoramides A–C (1-3).

Neuraminidase (NA) cleaves the glycosidic bond linkages of sialic acids to release the mature virions from infected cells and has been an attractive therapeutic target for anti-influenza agents. In our ongoing investigation of NA inhibitors in mushroom extracts, we found that the extract the fruiting body of Glaziella splendens potently inhibited neuraminidase. The fruiting bodies of G. splendens were extracted and partitioned successively with hexane, ethyl acetate, and butanol. The ethyl acetate soluble-layer was subjected to silica gel and Sephadex LH-20 column chromatographies, and MPLC to obtain five compounds (1–5). Their structures were determined by spectroscopic methods. NA inhibitory activity of these compounds was evaluated using NAs from recombinant rvH1N1, H3N2, and H5N1 influenza A viruses. One compound (1) was elucidated as a new azaphilone derivative, and four compounds (2–5) were identified as entonaemin A, comazaphilone D, rubiginosin A, and entonaemin B, respectively. Compounds 3 and 4 showed considerable inhibitory activity against three types of neuraminidases with the IC₅₀ values of 30.9, 41.8, and 35.7 µM for 3 and 46.5, 50.4, and 29.9 µM for 4, respectively. This study reveals that the fruiting bodies of G. splendens possess azaphilone derivatives with the NA inhibitory activity. This is the first report on the isolation of neuraminidase inhibitors from the fruiting bodies of G. splendens.

Five monoclonal antibodies (mAbs) that recognize human glutamate dehydrogenase (GDH) have been selected and designated as monoclonal antibodies hGDH60-6, hGDH60-8, hGDH63-10, hGDH63-11, and hGDH91-14. A total of five mAbs recognizing different epitopes of the enzyme were obtained, two of which inhibited human GDH activity. When total proteins of human homogenate separated by SDS- PAGE, were probed with mAbs, a single reactive protein band of 55 kDa, which co-migrated with purified recombinant human GDH was detected. When the purified GDH was incubated with each of the mAbs, its enzyme activity was inhibited by up to 58%. Epitope mapping analysis identified, two subgroups of mAbs recognizing different peptide fragments. Using the individual anti-GDH antibodies as probes, the cross reactivities of brain GDH obtained from human and other animal brain tissues were investigated. For the human and animal tissues tested, immunoreactive bands on Western blots appeared to have the same molecular mass of 55 kDa when hGHD60-6, hGHD60-8, or hGHD91-14 mAbs were used as probes. However, the anti-human GDH mAbs immunoreactive to bands on Western blots reacted differently on the immunoblots of the other animal brains tested, i.e., the two monoclonal antibodies hGDH63-10 and hGDH63-11 only produced positive results for human. These results suggest that human brain GDH is immunologically distinct from those of other mammalian brains. Thorough characterization of these anti-human GDH mAbs could provide potentially valuable tool as immunodiagnostic reagents for the detection, identification and characterization of the various neurological diseases related to the GDH enzyme.

Reactive oxygen species (ROS) contribute to the development of a number of neuronal diseases including ischemia. DJ-1, also known to PARK7, plays an important role in transcriptional regulation, acting as molecular chaperone and antioxidant. In the present study, we investigated whether DJ-1 protein shows a protective effect against oxidative stress-induced neuronal cell death in vitro and in ischemic animal models in vivo. To explore DJ-1 protein's potential role in protecting against ischemic cell death, we constructed cell permeable Tat-DJ-1 fusion proteins. Tat-DJ-1 protein efficiently transduced into neuronal cells in a dose- and time-dependent manner. Transduced Tat-DJ-1 protein increased cell survival against hydrogen peroxide (H2O2) toxicity and also reduced intracellular ROS. In addition, Tat-DJ-1 protein inhibited DNA fragmentation induced by H2O2. Furthermore, in animal models, immunohistochemical analysis revealed that Tat-DJ-1 protein prevented neuronal cell death induced by transient forebrain ischemia in the CA1 region of the hippocampus. These results demonstrate that transduced Tat-DJ-1 protein protects against cell death in vitro and in vivo, suggesting that the transduction of Tat-DJ-1 may be useful as a therapeutic agent for ischemic injuries related to oxidative stress.

PURPOSE: Anatomy of deep pelvis, narrow distal margin and tumor invasion into neighbor organ are obstacles for curative radical resection for advanced cancer of distal rectum. Technically, laparoscopic application after downstaging the tumor with preoperative concurrent chemotherapy (CCRT) may give a solution to overcome the anatomical difficulties. We compared the results of laparoscopic surgery in the patients who received CCRT with those of patients who had conventional surgery. MATERIALS AND METHODS: A continuous infusion of 5FU plus leucovorin and radiotherapy (50.4 Gy) in 28 fractions was given each patient as CCRT. They underwent D2 radical resection with TME and ANP for the rectal cancer in 4 weeks. RESULTS: Thirty three patients had laparoscopic resection such as LAR, colo-anal anastomosis and APR. The results were compared with 12 cases of the conventional resections. As a result of preoperative CCRT, the cancer was down-staged in 71%. Two year disease free survival was 75% and 74% in the group of conventional and laparoscopic resection, respectively (p=0.427). Ileus, voiding difficulty and leakage after surgery were not different between two groups. Weakness of ejaculation was noted in 9~11% of both groups. The DFS of the preoperative CCRT followed by radical resection in the groups with a response was more favorable than that in the group with progressive or stable disease. CONCLUSION: Radical resection of advanced distal rectal cancer could be done with performing a laparoscopic assisted operation after CCRT induced down-staging. We may suggest that laparoscopic assisted resection is a good treatment option as it doesn't increase the complications and it has a compatible survival rate to conventional surgery.
