BACKGROUND/OBJECTIVES: Obesity is associated with chronic inflammation. The spleen is the largest organ of the lymphatic system and has an important role in immunity.Obesity-induced inflammatory responses are triggered by Toll-like receptor (TLR)-myeloid differentiation primary response 88 (MyD88) pathway signaling. Phenethyl isothiocyanate (PEITC) and 3,3′-diindolylmethane (DIM), major dietary glucosinolates present in cruciferous vegetables, have been reported to produce anti-inflammatory effects on various diseases. However, the effects of PEITC and DIM on the obesity-induced inflammatory response in the spleen are unclear. The purpose of this study was to examine the antiinflammatory effects of PEITC and DIM on the spleen and their mechanism in high fat/ cholesterol diet (HFCD)-fed C57BL/6 mice.MATERIALS/METHODS: We established an animal model of HFCD-induced obesity using C57BL/6 mice. The mice were divided into six groups: normal diet with AIN-93G diet (CON), high fat diet (60% calories from fat) with 1% cholesterol (HFCD), HFCD with PEITC 30 mg/kg/ day or 75 mg/kg/day (HFCD+P30, HFCD+P75), and HFCD with DIM 1.5 mg/kg/day or 7.5 mg/kg/ day (HFCD+D1.5, HFCD+D7.5). Enzyme-linked immunosorbent assay was used to evaluate proinflammatory cytokine secretion. Western blot and quantitative polymerase chain reaction were used to analyze protein and mRNA levels of nuclear factor kappa B (NF-κB) p65, interleukin 6 (IL-6), cyclooxygenase 2 (COX-2), TLR2, TLR4, and MyD88 in spleen tissue. RESULTS: Serum IL-6 levels were significantly higher in the HFCD group than in groups fed a HFCD with PEITC or DIM. Levels of NF-κB p65 protein and TLR2/4, MyD88, NF-κB p65, IL-6, and COX-2 mRNA were significantly higher in the HFCD group than in the CON group and were reduced by the PEITC and DIM supplements. CONCLUSIONS PEITC- and DIM-supplemented diets improved splenic inflammation by modulating the TLR2/4-MyD88 pathway in HFCD-fed mice. We suggest that dietary glucosinolates may at least partially improve obesity-induced inflammation of the spleen.

BACKGROUND/OBJECTIVES: Unregulated inflammatory responses caused by hyperglycemia may induce diabetes complications. Hesperetin, a bioflavonoid, is a glycoside in citrus fruits and is known to have antioxidant and anticarcinogenic properties. However, the effect of inflammation on the diabetic environment has not been reported to date. In this study, we investigated the effect of hesperetin on proinflammatory cytokine secretion and its underlying mechanistic regulation in THP-1 macrophages with co-treatment LPS and hyperglycemic conditions.MATERIALS/METHODS: THP-1 cells differentiated by PMA (1 μM) were cultured for 48 h in the presence or absence of hesperetin under normoglycemic (5.5 mM/L glucose) or hyperglycemic (25 mM/L glucose) conditions and then treated with LPS (100 ng/mL) for 6 h before harvesting. Inflammation-related proteins and mRNA levels were evaluated by enzyme-linked immunosorbent assay, western blot, and quantitative polymerase chain reaction analyses. RESULTS: Hesperetin (0–100 μM, 48 h) treatment did not affect cell viability. The tumor necrosis factor-α and interleukin-6 levels increased in cells co-treated with LPS under hyperglycemic conditions compared to normoglycemic conditions, and these increases were decreased by hesperetin treatment. The TLR2/4 and MyD88 activity levels increased in cells co-treated with LPS under hyperglycemic conditions compared to normoglycemic conditions; however, hesperetin treatment inhibited the TLR2/4 and MyD88 activity increases. In addition, nuclear factor-κB (NF-κB) and Acetyl-NF-κB levels increased in response to treatment with LPS under hyperglycemic conditions compared to normoglycemic conditions, but those levels were decreased when treated with hesperetin. SIRT3 and SIRT6 expressions were increased by hesperetin treatment. CONCLUSIONS Our results suggest that hesperetin may be a potential agent for suppressing inflammation in diabetes.

OBJECTIVE: The purpose of our study is to find out the therapeutic effectiveness, reproductive outcome, and the diagnostic pathologic findings of the patients treated with resectoscopy. METHODS: We examined 110 patients who complained infertility, abnormal uterine bleeding and menorrhagia from May. 1995 to Dec. 2000 via office. Among the infertility and abnormal uterine bleeding patients with abnormal endometrial lesion, resectoscopy was performed and then the resected tissues was sended for pathologic examination, except IUA, uterine septum, and double uterus. After resectoscopy, we inserted Lippes loop and medicated premarin 2.5 mg, 54 days and medroxyprogesterone acetate 10 mg, 10 days to the IUA patients. In AUB patients, we only injected methergin for bleeding control. They visited office after 1 month, and the follow up for endometrial state was done through TVS, HSG, or hysteroscopy. RESULTS: Among the 44 infertility, 41 (93%) had normal endometrium findings. Of twenty pregnancy (48.8%), seven (35%) ended in a second trimester abortion, thirteen (65%) in a full-term infant. Among the 66 with abnormal uterine bleeding, the 62 (93%) had normal endometrial finding and normal menstruation pattern. But 2 patients recurred their symptom, then hysterectomy was done 3, 5 years later respectively. Most of the patients who performed histopathologic study were diagnosed as leiomyoma (59.4%), and then endometrial or endocervical polyp (25.3%) and residual placenta tissue (3.8%) respectively. CONCLUSION: The 101 patients (91.8%) improved their symptoms and intrauterine lesion. we suggest this technique which of diagnostic accuracy, cost safety, convenience, operation time, and patient's satisfaction.

Honeybee venom consists of melittin, apamin, phospholipase A2, hyaluronidase and other biologically active substances. It can cause potentially lethal reaction after mass envenomation. But, acute renal failure following multiple bee stings is rare and its pathogenesis is not well known. The possible causes of acute renal failure due to multiple bee stings are rhabdomyolysis, hemolysis and direct nephrotoxicity of bee venom. A 60-year-old man was the victim of a bee(Apis mellifera) attack. More than 780 bee stings were found over his face, neck and upper extremities. Gross hematuria, oliguria and generalized edema was developed within a few hours. He has fully recovered after general supportive care including hemodialysis. This case demonstrates that multiple bee stings may cause rhabdomyolysis with consequent acute renal failure.

In 2016, the clinical chemistry proficiency-testing program consisted of 21 programs, including the general chemistry program of the Korean Association of External Quality Assessment Service. The general chemistry program consisted of 28 test items and was conducted using two level control materials four times per year. Based on the information and results for each test item entered by each institution, statistical analysis data according to test method, instrument, and reagent were reported. The report comprised a general statistics report showing the characteristics of all participating institutions and a separate institutional report showing the evaluation data of individual institutions. The statistics included the number of participating institutions and the mean, standard deviation, coefficient of variation, median, minimum, and maximum values for each group. Each report was composed of a table, histogram, and Levey-Jennings chart showing the statistics for each test item. The results of each institution and the statistics for each classification are presented in the table showing the statistics, and a standard deviation index is presented together with a method classification and a classification by reagent companies. A total of 14 items, including albumin, were evaluated by more than 1,000 institutions. There was no significant difference in the distribution of the measurement methods compared with those used in the previous year. The coefficient of variation showed a tendency to increase as the concentration of the level control material decreased and as the number of participating institutions decreased for each test item. Most of them showed a coefficient of variation within 10%. These statistical data will be useful when interpreting the survey results from the institutions and selecting a test method.

Hypercalcemia rarely develops in patients with acute renal failure associated with rhabdomyolysis. If hypercalcemia occurs, it happens mostly in diuretic phase and rarely in oliguric phase. Secondary hyperparathyroidism, abnormal metabolism of Vitamin D, immobilization of patient, and release of calcium from injured muscle are considered as possible pathogenetic mechanisms of hypercalcemia in acute renal failure associated with rhabdomyolysis. Among them, dissolution of calcium from injured muscle into extracellular fluid is accepted as the major mechanism of pathogenesis of hypercalcemia. A twenty year old male patient, combat policeman, developed syncope in the course of regular physical training. He was diagnosed of acute renal failure associated with rhabdomyolysis at the hospital he initially visited. After being subjected to three sessions of acute hemodialysis, he was transferred to our hospital. During the treatment, laboratory test was performed upon his continuous complaints of lower extremity weakness. It showed severe hypercalcemia with plasma calcium level of 17.6 mg/dL. He was in oliguric phase at the time of this severe hypercalcemia. Patient's lower extremity weakness was gradually improved by hemodialysis using low calcium dialysate. He was discharged after his renal function became normal. He has been followed on regular basis.

PURPOSE: The proper reconstructive technique after a partial gastrectomy for an adenocarcinoma of the stomach is often debated, but few data exist to clarify the issue. The aim of this study was to compare retrospectively the early postoperative results and complications after different anastomoses used during a partial gastrectomy for a gastric adenocarcinoma. MATENRIALS AND METHODS: We reviewed the hospital records of 218 patients who had undergone a subtotal gastrectomy for gastric cancer at Chosun University Hospital between January 1997 and July 2000. Of the 218 subtotal gastrectomies performed with curative intent, 127 reconstructions were Billroth I gastrectomies and 91 were Billroth II gastrectomies. The following data were analyzed: age, sex, tumor size, gastric resection margin, timing of removal of the nasogastric tube, first bowel movement, resumption of oral feeding, and postoperative complications. RESULTS: The timing of removal of the nasogastric tube was significantly earlier in the Billroth Igroup than in the Billroth II group (27.9+/-13.9 hours and 69.7+/-68 hours, respectively)(P<0.05). Resumption of oral feeding was possible on day 4.6+/-1.5 in the Billroth I group and on dsy 5.2+/-1.5 in the Billroth II group (P<0.05). There were no anastomotic leakage, postoperative bleeding, and postoperative mortality among the patients in either group. CONCLUSION: the Billroth Igastrectomy should be considered for patients undergoing a partial gastric resection for gastric cancer due to its physiological benefits and acceptable rate of complication.

BACKGROUND AND OBJECTIVES: Life-threatening hypotension during percutaneous coronary interventions (PCI) is devastating for the patient and is associated with fatal adverse outcomes. The aim of our study was to assess the usefulness of intracoronary epinephrine in severe hypotension unresponsive to other measures during PCI. SUBJECTS AND METHODS: We analyzed the Pusan National University Yangsan hospital cardiac catheterization laboratory database to identify patients who underwent PCI from December 2008 to July 2012. The outcomes were changes of blood pressure (BP) and heart rate (HR) before and after intracoronary epinephrine and in-hospital mortality. RESULTS: A total of 30 patients who were initially stable and received intracoronary epinephrine for severe hypotension during PCI were included. Following administration of intracoronary epinephrine (dose 181+/-24.8 microgram), systolic and diastolic BP (from 53.8+/-13.0 mm Hg up to 112.8+/-21.2 mm Hg, from 35+/-7.6 mm Hg up to 70.6+/-12.7 mm Hg, respectively) and HR (from 39.4+/-5.1 beats/min up to 96.8+/-29.3 beats/min) were increased. Additionally, 21 patients (70%) showed hemodynamically acceptable responses to intracoronary epinephrine without the intraaortic balloon pump and temporary pacemaker during the PCI. In-hospital mortality was 17% (n=5). CONCLUSION: Although our study was small, intracoronary epinephrine was found to be well tolerated and resulted in prompt and successful recovery from severe hypotension in most patients when other measures were ineffective. Intracoronary epinephrine could be a safe and useful measure in patients developing severe hypotension during PCI.
