Objective To investigate effects of electroacupuncture (EA) on expression of intercellular adhesion molecule-1 (ICAM-1) in the rat of local cerebral ischemia-reperfusion. Methods Eighty SD rats were randomly divided into a normal control group, a sham operation group, a model group and an EA treatment group, 20 rats in each group. The thread-obstruction method was used for preparation of ischemia-reperfusion model. Zea-Longa rating criteria were used for evaluation of nervous function disorder; Immunohistochemical SABC method was used for detection of ICAM-1 expression in the microvascular endothelial cell of the ischemic brain region, and ELISA method for the soluble ICAM-1 (slCAM-1) content in peripheral blood. Re. suits After cerebral ischemia-reperfusion, both ICAM-1 expression level in the microvascular endethelium cell of the ischemic brain region and slCAM-1 content in the peripheral blood significantly increased in the model group as compared with the normal group and the sham operation group (P〈0.01); After EA treatment, the ICAM-1 expression level in the microvascular endothelial cell of the ischemic brain region and slCAM-1 content in the peripheral blood were significantly down-regulated in the EA treatment group as com- pared with the model group (P〈 0.05). Conclusion After cerebral ischemia-reperfusion, the microvascular endothelial cell of the ischemic brain region releases ICAM-1, which induces inflammatory injury of cerebral tissues; EA treatment can decease the expression of ICAM-1, so as to prevent the brain from the injury. 展开更多

AIM: To study the levels of serum soluble intercellular adhesion molecule-1 (sICAM-1), plasma D-lactate and diamine oxidase (DAO) in patients with inflammatory bowel disease (IBD), and the potential clinical significance. METHODS: Sixty-nine patients with IBD and 30 healthy controls were included in this study. The concentration of sICAM-1 was detected with enzyme-linked immunosorbent assay, the level of D-lactate and DAO was measured by spectroscopic analysis, and the number of white blood cells (WBC) was determined by routine procedure. RESULTS: The levels of sICAM-I, DAO, and WBC in IBD patients were significantly higher than those in the control group (P 〈 0,01), sICAM-I in IBD patients was found to be closely related to the levels of DAO and D-lactate (212.94 ± 69.89 vs 6.35 ± 2.35, P = 0.000), DAO 212.94 ± 69.89 vs 8.65 ± 3.54, P = 0.000) and WBC (212.94 ± 69.89 vs 7.40 ± 2.61, P = 0.000), but no significant difference was observed between patients with ulcerative colitis and patients with Crohn's disease. The post-treatment levels of sICAM-I, D-lactate and WBC were significantly lower than before treatment (sICAM-I 206.57 ± 79.21 vs 146.21 ± 64.43, P = 0.000), (D-lactate 1.46 ± 0.94 vs 0.52± 0.32, P = 0.000) and (WBC 7.24 ± 0.2.33 vs 5.21 ± 3.21, P = 0.000). CONCLUSION: sICAM-1, D-lactate and DAO are closely related to the specific conditions of IBD, and thus could be used as a major diagnostic index. 展开更多

AIM: Nuclear factor kappa B (NF-κB) regulates a large number of genes involved in the inflammatory response to critical illnesses, but it is not known if and how NF-KB is activated and intercellular adhesion molecule-1 (ICAM-1) expressed in the gut following traumatic brain injury (TBI). The aim of current study was to investigate the temporal pattern of intestinal NF-κB activation and ICAM-1 expression following TBI. METHODS: Male Wistar rats were randomly divided into six groups (6 rats in each group) including controls with sham operation and TBI groups at hours 3, 12, 24, and 72, and on d 7. Parietal brain contusion was adopted using weight-dropping method. All rats were decapitated at corresponding time point and mid-jejunum samples were taken. NF-KB binding activity in jejunal tissue was measured using EMSA. Immunohistochemistry was used for detection of ICAM-1 expression in jejunal samples. RESULTS: There was a very low NF-κB binding activity and little ICAM-1 expression in the gut of control rats after sham surgery. NF-KB binding activity in jejunum significantly increased by 160% at 3 h following TBI (P<0.05 vs control), peaked at 72 h (500% increase) and remained elevated on d 7 post-injury by 390% increase. Compared to controls, ICAM-1 was significantly up-regulated on the endothelia of microvessels in villous interstitium and lamina propria by 24 h following TBI and maximally expressed at 72 h post-injury (P<0.001). The endothelial ICAM-1 immunoreactivity in jejunal mucosa still remained strong on d 7 post-injury. The peak of NF-κB activation and endothelial ICAM-1 expression coincided in time with the period during which secondary mucosal injury of the gut was also at their culmination following TBI. CONCLUSION: TBI could induce an immediate and persistent up-regulation of NF-κB activity and subsequent up-regulation of ICAM-1 expression in the intestine. Inflammatory response mediated by increased NF-κB activation and ICAM-1 expression may play an important role in the pathogenesis of acute gut mucosal injury following TBI. 展开更多

To compare the diagnostic value of soluble intercellular adhesion molecule 1 (sICAM-1) with that of c-reactive protein (CRP) for detecting chorioamnionitis (CAM) in serum of women with premature rupture of membranes (PROM), 55 pregnant women with PROM, including 18 pregnant women with preterm premature rupture of membranes (PPROM) and 20 normal pregnant women at term (TPROM) were studied. Maternal serum were measured by Sandwish enzyme-linked immunoabsorbent assay (ELISA) for sICAM. CAM was histologically confirmed after delivery. The results revealed that (1) maternal serum levels of sICAM-1 and CRP were significantly higher in women with PROM than those without it; (2) maternal serum levels of sICAM-1 and CRP were significantly higher in women with CAM than those without it; (3) serum levels of sICAM-1 in PPROM women were similar to those in TPROM women, whereas serum levels of CRP in PPROM women were significantly higher than those in TPROM women; (4) the sensitivity, specificity, positive predictive value, negative predictive value, Kappa index and area under receiver operating characteristic (ROC) curve of maternal serum sICAM-1 (cutoff 104.7 ng/ml) and CRP(cutoff 1.03 mg/dl) for diagnosing CAM were 100 %, 91.2 %, 87.5 %, 100 %, 0.20, 0.995 and 81.0 %, 73.5 %, 65.4 %, 86.2 %, 0.13, 0.811, respectively; (5) among the mild histological CAM group, severe histological CAM group and clinical CAM group, the difference in maternal serum levels of sICAM-1 were significantly (P<0.001), with the order of concentration from high level to low level corresponding to the severity of CAM. It is concluded that maternal serum level of ICAM-1 is superior to that of CRP as biomarker for diagnosing intraamniotic infection in pregnant women with PROM. 展开更多

BACKGROUND: Previous studies have confirmed the neuroprotective effect of mild hypothermia on ischemic brain injury. OBJECTIVE: To investigate the effects of mild hypothermia on intercellular adhesion molecule-1 expression and serum interleukin-6 levels in ischemic brain tissues of focal brain ischemia rats, and to explore the neuroprotective effects of mild hypothermia on ischemic brain injury. DESIGN, TIME AND SETTING: A randomized, controlled, neurobiological experiment was performed at the Central Laboratory, First Affiliated Hospital, Xinxiang Medical College, China from February to July 2006. MATERIALS: Thirty healthy, adult, Sprague Dawley rats were used to establish middle cerebral artery occlusion models using the suture method, The immunohistochemistry (streptavidin-biotin-peroxidase complex method) kit was purchased from Boster, China. Interleukin-6 radioimmunoassay was supplied by Institute of Radioimmunity, Technology Development Center, General Hospital of Chinese PLA. METHODS: The rats were equally and randomly assigned into mild hypothermia and control groups, and middle cerebral artery occlusion models were established. The rectal temperature was maintained at (37 ±0.5)℃ in the control group. In the mild hypothermia group, the rectal temperature was maintained at (33±1)℃. MAIN OUTCOME MEASURES: At 12 hours after model establishment, the ischemic brain hemispheres were coronally sliced at the level of the optic chiasm. The number of intercellular adhesion molecule-1-positive vessels per high-power field was observed with an optical microscope. Serum interleukin-6 levels were measured by radioimmunoassay. RESULTS: Compared with the control group, intercellular adhesion molecule-1 and serum interleukin-6 expressions were significantly decreased in ischemic brain tissues of the mild hypothermia group (P 〈 0.01). CONCLUSION: Mild hypothermia exhibits a neuroprotective effect by reducing serum interleukin-6 and intercellular adhesion molecule-1 expression following cerebral ischemia. 展开更多

To understand the role of intercellular adhesion molecule-1 (ICAM-1) in immune response of the inner ear, inner ear immune response was induced in rats by inoculation of keyhole limpet hemocyanine (KLH) into the scala tympani of the animals who had been systemically sensitized. The expression of ICAM-1 in the inner ear was immunohistochemically examined. ICAM-1 was found in the epithelium of the spiral modiolar vein (SMV) with its collecting venules (CVs) as early as 6 h after challenge. Expression of ICAM-1 was observed on the epithelium of the endolymphatic sac (ES) and perisaccular region at 12 h. The intensity of ICAM-1 staining reached its peak within 24 - 48 h in these sites of the inner ear. By day 28, most specimens were devoid of appreciable staining for ICAM-1. Our study demonstrates that adhesion molecules play an important role in extravasation of inflammatory cells from the systemic circulation in the process of inner ear immune response. It also shows that cytokines that control expression of adhesion molecules may be released by cells outside ES, besides those cells in the ES. 展开更多

AIM:To determine if serum inter-cellular adhesion molecule 1(ICAM-1)is an early marker of the diagnosis and prediction of severe acute pancreatitis(SAP) within 24 h of onset of pain,and to compare the sensitivity,specificity and prognostic value of this test with those of acute physiology and chronic health evaluation(APACHE)Ⅱscore and interleukin-6(IL-6). METHODS:Patients with acute pancreatitis(AP)were divided into two groups according to the Ranson's criteria:mild acute pancreatitis(MAP)group and SAP group.Serum ICAM-1,APACHEⅡand IL-6 levels were detected in all the patients.The sensitivity,specificity and prognostic value of the ICAM-1,APACHEⅡscore and IL-6 were evaluated. RESULTS:The ICAM-1 level in 36 patients with SAP within 24 h of onset of pain was increased and was significantly higher than that in the 50 patients with MAP and the 15 healthy volunteers(P<0.01).The ICAM-1 level(25 ng/mL)was chosen as the optimum cutoff to distinguish SAP from MAP,and the sensitivity,specificity,positive predictive value,negative predictive value(NPV),positive likelihood ratio and negative likelihood ratio were 61.11%,71.42%,0.6111,0.7142, 2.1382 and 0.5445,respectively.The area under the curve demonstrated that the prognostic accuracy of ICAM-1(0.712)was similar to the APACHE-Ⅱscoring system(0.770)and superior to IL-6(0.508)in distinguishing SAP from MAP. CONCLUSION:ICAM-1 test is a simple,rapid and reliable method in clinical practice.It is an early marker of diagnosis and prediction of SAP within the first 24 h after onset of pain or on admission.As it has a relatively low NPV and does not allow it to be a stand-alone test for the diagnosis of AP,other conventional diagnostic tests are required. 展开更多

The expression of intercellular adhesion molecule-1 (ICAM-1) in the pathogenesis of heroin-induced acute lung injury (ALI) in rats was investigated. The model of ALI was established by intravenous injection of heroin into tail vein in rats. Thirty-six rats were randomly divided into heroin-treated groups (1 h, 2 h, 4 h, 6 h and 24 h) and normal control group. Changes in histopathologic morphology and biological markers of ALI were measured. The expression of ICAM-1 in lung tissue was detected by using immunohistochemistry and RT-PCR. The results showed that the W/D ratio and protein contents in BALF of the heroin-treated groups were significantly higher than that of the control group (P<0.01). The histopathological changes in the lung tissue were more obvious in heroin-treated groups. The ICAM-1 protein and mRNA expression in the lung tissue of heroin-treated groups were significantly increased as compared with that of the control group (P<0.01), and correlated with the ALI parameters in a time-dependent manner. Increasing of ICAM-1 expression was involved in the formation of heroin-induced lung injury. Furthermore, the level of expression was positively correlated with the severity of lung injury. 展开更多

Metkods: ICAM 1 expression on cultured neonatal rat cardiac myocytes infected by CoxB3 was determined through enzyme linked immunosorbent assay (ELISA) analysis. Lymphocyte-myocyte adhesion was observed with adherence assay and monoclonal antibodies to adhesion molecule inhibition. Results:ICAM-1 expression on cardiac my ocytes was markedly induced after exposure to CoxB3 100 or 200 TCID50/ml infectious dose for 24~48 h (P<0. 05). Adhesion of rat activated lymphocytes to myocytes was stimulated by CoxB3 infection,and the effects of CoxB3 infection on adherence was significantly inhibited by anti-lymphocyte function antigen-1 (LFA-12)monoclonal antibodies (inhibition rate 40. 6% and 26. 45 % respectively). Couclusion:CoxB3 infec tion promotes lymphocyte-myocyte adhesion through inducing ICAAM-1 expression on cardiac myocytes. 展开更多

Background Intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) are two important cytokines in inflammatory response, which may induce rolling and adhesion of both leukocytes and lymphocytes, while modulating vascular permeability at the same time. These adhesion molecules usually serve as surrogate markers of activation and injury of vascular endothelial cells. Tumor necrosis factor-α (TNF-α) is a key factor to induce the expression and production of the above cell adhesion molecules. However, it remains to be elucidated whether exogenous ubiquitin exerts any effect on the cytokines in sepsis-induced ALI. Methods Sixty mice were devided randomly into five groups with twelve mice in each group, i.e. CLP group, SHAM group, UB1 group (10 mg/kg), UB2 group (5 mg/kg) and UB3 group(1 mg/kg). Mice of SHAM group underwent sham operation, and other four groups underwent CLP. Six hours after surgery, mice of three UB groups received ubiquitin by caudal vein injection while CLP and SHAM group received vehicle. Seven hours after surgery, blood and lungs of all mice were collected. ICAM-1, VCAM-1 and TNF-α level of 9% lung homogenate and serum TNF-α level were measured by ELISA. Results Pulmonary ICAM-1, VCAM-1 and TNF-α level of three UB groups were lower than CLP and SHAM group, and there were several comparisons with a statistically significant difference. Serum TNF-α level of three UB groups were slightly lower than CLP group, but far higher than SHAM group. Pulmonary ICAM-1 level, VCAM-1 level and serum TNF-α level of UB3 group were lower than UB1 and UB2 group, and there was a significant difference in VCAM-1 between UB3 and UB1 group. Pulmonary TNF-α level of UB3 group was slightly higher than UB1 and UB2 group. 展开更多

Pingyangmycin (bleomycin A5 hydrochloride,PYM) is one of the anti-neoplastic agents which have been commonly used to treat venous malformations.However,the underlying mechanism by which PYM treats venous malformations remains poorly understood.It was reported that venous endothelial cells could recruit neutrophils via adhesion molecules (E-selectin,ICAM-1,ICAM-3,VCAM-1) during the acute/chronic inflammation and subsequent histological fibrosis after sclerotherapy with PYM.This study explored if the expression of E-selectin,ICAM-1,ICAM-3 and VCAM-1 in human venous malformation endothelial cells could be affected by PYM.HVMECs were cultured from human venous malformation tissue.Expressions of E-selectin,ICAM-1,ICAM-3 and VCAM-1 on HVMECs in response to PYM were analyzed by cell ELISA.The relative levels of mRNA expression in the cells were semi-quantified.The results showed that PYM up-regulated the expressions of E-selectin,ICAM-3,VCAM-1 and ICAM-1 in both time-and concentration-dependent manner.Our findings suggested that PYM could induce the expression of adhesion molecules in HVMECs,which might be a possible mechanism by which sclerotherapy by intralesional injection of PYM treats venous malformations. 展开更多

OBJECTIVE: To quantitatively measure the temporal profiles of intercellular adhesion molecule-1 (ICAM-1) protein in mouse brain after middle cerebral artery occlusion (MCAO). METHODS: Adult male CD-1 mice received 0, 3, 6, 12, 24, 48 and 72 hour(s) of permanent MCAO with an intraluminal suture technique. The degree and the extent of occlusion were determined using a laser Doppler flowmeter. ICAM-1 positive expression in ischemic regions was determined immunohistochemically and ICAM-1 protein was quantitatively measured using immunoprecipitation and Western blot analysis. RESULTS: After MCAO, surface cerebral blood flow (CBF) in the ischemic hemisphere decreased to 9%-15% of the baseline in each time point of 7 to 8 animals. There were no significant differences in CBF measurement during occlusion between groups. Immunohistochemistry showed that ICAM-1 positive microvascular endothelial cells were observed both in the ischemic core and in the perifocal region. There was a tendency for increasing expression of ICAM-1 positive microvascular endothelial cells from the ischemic core to the ischemic margin. Western blot analysis showed that ICAM-1 expression in the ischemic hemisphere began to increase 3 h after MCAO, peaked at 6 h to 12 h, and persisted to 72 h. CONCLUSIONS: ICAM-1 expression increases in mice with permanent MCAO because ICAM-1 can mediate leukocyte-endothelial adhesion and progression of leukocyte infiltration after permanent focal cerebral ischemia. ICAM-1 is one of the important factors participating in ischemic cerebral damage and pathogenesis of stroke. 展开更多

Background Inflammation is a major cause of restenosis after coronary stenting. Intercellular adhesion molecule-1 (ICAM-1) is an important adhesion molecule that plays a key role in the tight adhesion between leukocytes and vascular endothelium. The object of this study was to investigate the association between the K469E polymorphism of the ICAM-1 gene and restenosis after coronary stenting in North Chinese population.Methods The ICAM-1 K469E polymorphism was genotyped using polymerase chain reaction-restriction fragment length polymorphism method in 124 patients who had undergone coronary stenting and coronary angiography at least 3 months earlier. Information on clinical risk factors and procedure-related data were also collected.Results Of 124 enrolled patients in total, there were 72 cases of in-stent restenosis. The restenosis rate in this population was 58.1 %. The frequencies of the three possible genotypes of the ICAM-1 K469E polymorphism were: KK genotype 50. 8%, EE genotype 41. 9%, and EK genotype 41. 9%. Among restenosis patients, the frequency of the KK genotype was 58. 3% and the frequency of E allele carriers was 41.7%. Among non-restenosis patients, the frequency of the KK genotype was 40.4%, and the frequency of E allele carriers was 59. 6%. The distribution of these two genotype groups between restenosis and non-restenosis patients was significantly different (P=0. 049). Using multivariate logistic regression, the difference between the two groups was more apparent. The odds ratio of KK homozygotes vs E allele carriers was 2. 6, with 95% confidence interval 1. 2 -5. 8 ( P = 0. 018). After grading of risk factors, we found that the KK genotype was a stronger predictor of in-stent restenosis in obesity or hyperlipemia patients, with an odds ratio of 9. 3 and 3. 7, respectively (P <0. 05).Conclusion In our study population, KK homozygotes of the ICAM-1 codon 469 mutation had a higher risk of restenosis after coronary stenting, especially in the case of obese or hyperlipemia patients. 展开更多

Background In addition to elevated concentrations of cytokines, patients with congestive endothelial dysfunction and increased plasma concentrations of adhesion molecules heart failure (CHF) show ke intercellular adhesion molecule-1 (ICAM-1). Furthermore, the concentration of cardiotrophin-1 (CT-1) - a cytokine of the interleukin-6 superfamily - is increased in CHF. We tested the hypothesis whether CT-1 is able to induce ICAM-1 in human umbilical vein endothelial cells (HUVEC). Furthermore we examined the signalling mechanisms of CT-1 mediated ICAM-1 expression. Methods Confluent layers of HUVEC were incubated with increasing concentrations of CT-1 (5 to 100 ng/ml) for different periods. ICAM-1 mRNA was determined by real-time polymerase chain reaction (PCR) and ICAM-1 surface expression by fluorescence-activated cell sorter (FACS) analysis and soluble ICAM-1 (slCAM-1) in the culture supernatant by enzyme linked immunosorbent assay (ELISA). To clarify the signalling pathway of CT-1 induced ICAM-1 expression we used various inhibitors of possible signal transducing molecules, electromobility shift assay (EMSA) and Western blot analysis. Results CT-1 induced ICAM-1 mRNA (1.8±0.8 fold increase compared to unstimulated cells after 6 hours) and protein (1.4±0.2 fold increase compared to unstimulated cells after 48 hours) in HUVEC in a time- and concentration-dependent manner. EMSA experiments show that CT-1 causes nuclear factor (NF) κB activation. Because parthenolide could inhibit CT-1 induced ICAM-1 expression NFκB activation is required in this pathway. CT-1 did not activate extracellular signal regulated kinases (ERK), c-Jun N-terminal kinase (JNK) and p38. Conclusion CT-1 is able to induce ICAM-1 in endothelial cells by NFκB activation. These results may explain in part elevated ICAM-1 concentrations in patients with CHF and endothelial dysfunction. 展开更多
