BACKGROUND: Corrected QT (QTc) interval can be modulated by sympathetic and parasympathetic balance. Tracheal intubation causes significant prolongation of the QTc interval due to sympathetic stimulation. This study was designed to elucidate the relationship between baseline autonomic nervous system activity and QTc prolongation after endotracheal intubation using heart rate variability (HRV). METHODS: Sixty-six healthy patients were included and the baseline HRV data were recorded for 5 min before anesthesia. Power spectrum densities were calculated for low frequencies (LF, 0.04-0.15 Hz) and high frequencies (HF, 0.15-0.4 Hz), defined as either LF's or HF's relative part of the total power. Anesthesia was induced with sevoflurane and vecuronium was given. The QTc interval, heart rate (HR) and mean arterial pressure (MAP) were measured before induction (baseline), before laryngoscopy (pre-intubation) and immediately after the intubation (post-intubation). RESULTS: The QTc interval change at post-intubation from baseline (DeltaQTc) showed a significant negative correlation with the HF (r = 0.34, P = 0.006) and positive correlation with LF/HF ratio (r = 0.37, P = 0.005). Patients were retrospectively divided into low-HF/LF (<2.5, n = 44) and high-HF/LF group (>2.5, n = 22). The DeltaQTc was statistically higher in the high-LF/HF group compared to that in the low-LF/HF group (P = 0.048). The HR and MAP at baseline, pre-intubation and post-intubation were not different between two groups. CONCLUSIONS: The QTc interval prolongation after endotracheal intubation is influenced by baseline autonomic conditions and can be exaggerated in patients with activated sympathetic activity or depressed parasympathetic activity.

PURPOSE: Although there is no clinical evidence of nephrotoxicity with the volatile anesthetics currently used in general anesthesia, a better agent should be needed in terms of preserving postoperative renal function in living kidney donors who have only single remaining kidney. The purpose of the current retrospective, single-center study was to evaluate and compare renal function of living kidney donors after nephrectomy under either sevoflurane or desflurane anesthesia. MATERIALS AND METHODS: From January 2006 through December 2011, a total of 228 donors undergoing video assisted minilaparotomy surgery nephrectomy for kidney donation were retrospectively enrolled in the current study. The donors were categorized into a sevoflurane group or desflurane group based on the type of volatile anesthetic used. We collected laboratory data from the patients preoperatively, immediately after the operation, on the first postoperative day and on the third postoperative day. We also compared renal function of the kidney donors after donor nephrectomy by comparing creatinine level and estimated glomerular filtration rate (eGFR). RESULTS: The decrease in renal function after surgery in both groups was the most prominent on the first postoperative day. There were no significant differences between the two groups in postoperative changes of creatinine or eGFR. CONCLUSION: Sevoflurane and desflurane can be used safely as volatile anesthetics in donors undergoing nephrectomy.

C-Reactive protein (CRP) is an acute phase response protein synthesized in the liver as a response to various inflammation. CRP is extensively used as a general marker for inflammation in clinical medicine. A forensic applications of the CRP using postmortem samples have been studied in oversea. We have compared CRP in the between antemortem and postmortem samples and studied stability of postmortem blood samples for CRP test. In 69 consecutive autopsy cases, we have analysed heart blood samples (69 cases), peripheral blood samples (33 cases), and vitreous humor samples (60 cases). Postmortem CRP was elevated in 25 cases (36.2%) and possible causes of CRP elevation were inflammatory disease except one case (unknown). Postmortem CRP test shows sensitivity 86.7%, specificity 80%, positive predictive value 92.9%, and negative predictive value 66.7% for inflammation based on 20 cases with antemortem CRP results. The postmortem CRP levels were similar in the heart blood samples and peripheral blood samples. Vitreous humor samples are not useful in postmortem CRP testing. And both whole blood and serum samples are stable in room temperature until 31 days. We conclude that serum from heart blood is best suitable sample for postmortem CRP test and postmortem CRP test is useful in routine autopsy practice to detect inflammatory disease such as sepsis. From the view of postmortem point, we desire that this valuable test should be used in routine autopsy practice in Korea.

Ludwig's angina is a progressive gangrenous cellulitis and edema of the soft tissues of the neck and floor of the mouth. Ludwig's angina can be fatal as a result of progressive swelling of the soft tissues of the neck and elevation and posterior displacement of the tongue, resulting in airway obstruction. We report the case of a 77-yearold man who was admitted to the dental hospital with a toothache and headache. He was diagnosed with left submandibular space abscess. Four days post-admission, the submandibular and submental abscess was incised and drained. After the operation, the patient suddenly developed dyspnea and suffered cardiopulmonary arrest and died. An autopsy was performed, and exploration of the neck revealed a submental and submandibular abscess with massive inflammation, edema, and an abscess in multiple layers of the cervical subcutaneous tissue. After autopsy, the cause of death was confirmed as Ludwig's angina with a deep neck abscess. Ludwig's angina is a rapidly progressive cellulitis that often results in death by asphyxia or sepsis and is rarely seen in a forensic autopsy practice. Here in we report a case of Ludwig's angina and present a review of the literature.

In this study, we aimed to determine the antinociceptive and/or anti-inflammatory effect of Bang-Poong (BP, Radix Ledebouriellae) on Freund's adjuvant-induced arthritis in rats. Traditionally, BP has been used to treat several inflammatory diseases such as arthritis. Whole BP is extracted into two fractions that were ethylacetate and hexane-soluble fractions. Adult Sprague-Dawley rats (n=30, 130-150 g) were subcutaneously administered by the Freund's complete adjuvant (FCA) into the plantar surface of right hindpaw. Twelve days after the injection of FCA, the rats initially showed typical inflammatory edema and arthritis-related symptoms on the contralateral side (i.e. left hindpaw). Both antinociceptive (evaluation of mechanical, thermal pain threshold and analysis of spinal Fos expression) and anti- inflammatory (evaluation of paw edema, serum interleukin-6 level and x-ray analysis) effect of BP extracts were examined. The ethylacetate fraction of BP (BPE) significantly suppressed the FCA-induced paw edema as well as the serum level of interleukin-6 and it alleviated the radiological changes. Moreover, both mechanical and thermal hyperalgesia were attenuated by the treatment of BPE. In addition, spinal Fos expression that was increased by FCA- injection was suppressed in BPE group. Therefore, this study showed that BPE produced significant both antinociceptive and anti-inflammatory effects on FCA- induced arthritis in rats, while hexane fraction of BP did not show these effects. In conclusion, it is suggested that the ethylacetate fraction of BP is recommended to alleviate the arthritis-related symptoms in human according to the results of this study.

BACKGROUND: Paeonia j ap onica Miyabe is a medicinal plant which has been widely used as a component of blood-building decoctions (Chinese medicinal concept : Bu-Xie). The immunopharmacological characteristics of the extract of Paeonia j ap onica (PJ) were investigated. METHODS: The effects of fractions of PJ extract on lymphocyte proliferation were measured by H3 -thymidine incorporation assay . The proliferated lymphocyte subsets were analyzed in flow cytometry . The subset cell populations of spleen cells were separated by magnetic cell separation system, and their proliferation by the extract were investigated. The effect of the extract on antibody production was determined in mice challenged with sheep red blood cells (SRBC) using hemolytic plaque forming cell assay. RESULTS: Spleen cells were proliferated by water extract of PJ. Polysaccharide fraction (PJ-P) of the extract was most active in the proliferation. It was found in flow cytometry that the lymphocyte subset proliferated by PJ-P was B cell population. Among the separated subset cell populations, T cell-depleted cell population and macrophage-depleted cell population were most proliferated by PJ-P. However, positively selected populations of B cells and T cells were not proliferated by PJ-P. These result s indicate that B cell proliferation by PJ-P may require the assistance of macrophages or T cells. These result s suggest that firstly PJ-P may stimulate macrophages or T cells, and then B cells are activated. The number of antibody-secreting cells was increased by administration of PJ-P in mice immunized with SRBC as a T-dependent antigen. CONCLUSION: These result s suggest that macrophages and accessory cells are directly activated by PJ-P and then helper T cells and B cells are indirectly activated. As the results, immune responses might be coordinately improved. In conclusion, PJ-P, a polysaccharide of P. j ap onica, may be a characteristic immunostimulator, which is analogous to polysaccharides such as lentinan, PSK and ginsan.

BACKGROUND: The role of allogeneic hematopoietic cell transplantation (allo-HCT) compared with consolidation chemotherapy alone in intermediate-risk acute myeloid leukemia (AML) patients with wild-type nucleophosmin/negative or a low level of Fms related tyrosine kinase 3 internal tandem duplication (NPM1(wt)/FLT3-ITD(neg/low)) has not yet been elucidated. METHODS: In this study, we retrospectively investigated 88 patients newly diagnosed with AML who received intensive induction chemotherapy at Kyungpook National University Hospital from March 2015 to July 2017. The selection criteria included the presence of results on genetic abnormalities including NPM1 and FLT3-ITD. RESULTS: According to the European LeukemiaNet (ELN) risk classification, 25 patients (28%) were categorized as favorable, 44 (50%) as intermediate, and 19 (22%) as adverse risk. Among the intermediate-risk patients, 40 were identified as NPM1 wt/FLT3-ITDneg/low. Among the patients with NPM1(wt)/FLT3-ITD(neg/low), complete remission (CR) was achieved in 26 patients out of 40 (65%). One-year overall survival (OS) rate was 100% in the favorable-risk group and 87.9% in the NPM1(wt)/FLT3-ITD(neg/low) group (P=0.233). Among the intermediate-risk NPM1(wt)/FLT3-ITD(neg/low) patients, there was no survival benefit with allo-HCT (N=19) compared to consolidation chemotherapy (N=21; P=0.372). In the multivariate analysis, the ELN risk group [hazard ratio (HR), 6.36; P=0.019] and the achievement of CR (HR, 2.95; P=0.017) were both identified as factors affecting OS of patients with newly diagnosed AML. CONCLUSION: Among the AML patients, intermediate-risk NPM1(wt)/FLT3-ITD(neg/low) patients and favorable-risk patients showed similar OS rates. Our results suggested that allo-HCT might have limited clinical benefit for the intermediate-risk NPM1(wt)/FLT3-ITD(neg/low) patients. Well controlled studies are needed to confirm the current results.
