Intra-Abdominal Hypertension and Abdominal Compartment Syndrome in Liver Diseases

Intra-abdominal hypertension (IAH) is defined as an intra-abdominal pressure (IAP) above 12 mmHg. Abdominal compartment syndrome (ACS) is defined as an IAP above 20 mmHg with evidence of organ failure. Moreover, IAH/ACS is a condition that can cause acute renal failure, respiratory failure, circulatory disease, gastrointestinal dysfunction, and liver failure due to elevated IAP. The incidence of IAH/ACS increases in the more critically ill patient and is associated with significantly increased morbidity and mortality. Ascites, blood, or tumors increase IAP. In liver cirrhosis, massive ascites is often encountered. Hence, preventing IAH/ACS conditions may improve outcomes of patients with liver disease

Molecular targeting of hepatocyte growth factor by an antagonist, NK4, in the treatment of rheumatoid arthritis

INTRODUCTION: Hepatocyte growth factor (HGF) is a potent proangiogenic molecule that induces neovascularization. The HGF antagonist, NK4, competitively antagonizes HGF binding to its receptor. In the present study, we determined the inhibitory effect of NK4 in a rheumatoid arthritis (RA) model using SKG mice. METHODS: Arthritis was induced in SKG mice by a single intraperitoneal injection of β-glucan. Recombinant adenovirus containing NK4 cDNA (AdCMV.NK4) was also injected intravenously at the time of or 1 month after β-glucan injection. Ankle bone destruction was examined radiographically. The histopathologic features of joints were examined using hematoxylin and eosin and immunohistochemical staining. Enzyme-linked immunosorbent assays were used to determine the serum levels of HGF, interferon γ (IFN-γ, interleukin 4 (IL-4) and IL-17 production by CD4(+ )T cells stimulated with allogeneic spleen cells. RESULTS: The intravenous injection of AdCMV.NK4 into SKG mice suppressed the progression of β-glucan-induced arthritis. Bone destruction was also inhibited by NK4 treatment. The histopathologic findings of the ankles revealed that angiogenesis, inflammatory cytokines and RANKL expression in synovial tissues were significantly inhibited by NK4 treatment. Recombinant NK4 (rNK4) proteins inhibited IFN-γ, IL-4 and IL-17 production by CD4(+ )T cells stimulated with allogeneic spleen cells. CONCLUSIONS: These results indicate that NK4 inhibits arthritis by inhibition of angiogenesis and inflammatory cytokine production by CD4(+ )T cells. Therefore, molecular targeting of angiogenic inducers by NK4 can potentially be used as a novel therapeutic approach for the treatment of RA

Application of CO-oximeter for Forensic Samples

CO-oximeter is routinely used in clinical practice, and it has been applied in the field of forensic medicine. It is a simultaneous and nondestructive technique for the analysis of total hemoglobin (Hb) and various Hb species, such as oxyhemoglobin, reduced hemoglobin, carboxyhemoglobin, and methemoglobin. It automatically measures the proportion of each species of Hb and oxygen contents. This is an easy, rapid, and convenient way as the laboratory test. Since there are many advantages such as no necessity of sample preparation, easy handling, and portability, it may provide valuable information for forensic diagnosis. In the present paper, we discuss about the diagnostic application of CO-oximeter in the field of forensic medicine

Simplified Analysis of Toxic Gaseous Substance in Forensic Practice: Experiences from Japan

Toxicological examination in forensic practice is important for the proper diagnosis of acute poisoning. We have discussed the properties and features of poisoning incidents due to gaseous substances and elaborated on the simplified analytical techniques and apparatus used for their identification and quantitation for forensic purposes. Briefly, we have explained the simplified analysis of toxic gaseous substances such as carbon monoxide, hydrogen cyanide, hydrogen sulfide, and helium in blood. The techniques used include color testing, gas chromatography, detector tube, oximeter, and spectrophotometric method. In doing so, we have shared our experiences and highlighted the fact that the analysis of gaseous substances can be performed using readily available laboratory tools and equipment. We have emphasized the need and usefulness of the reference data tables for guiding forensic diagnosis. We hope that the above overview will assist other colleagues to implement such simplified techniques for the advancement of forensic medicine practice
