Changes of soluble intercellular adhesion molecule-1 in the serum from patients with acute cerebral infarction

objective: To observe the changes of soluble intercellular adhesion molecule-1(sICAM-1) in the serum of patients with acute cerebral infarctlon (ACI) and their clinical significance. Methods: The concen-tration of sICAM-1 in the serum of 91 patients with ACI was determined with ELISA and then the results were compared wlth those of 43 patients with cerebral hemorrhage and 30 healthy individuals. Results: In the 24th hour after infarction. the concentration of sICAMu-1 in the serum was significantly higher in patients with ACI than in patients with cerebral hemorrhage and normal controls (P< 0. 01). In the patients with ACI, the concentration exhibited an decreasing tendency in the period from the 24th hour to the 14th day andwas correlated with the focal size of cerebral infarction. During the first 14 days after infarction, the concen-tration was significantly higher in the patients with the complication of infection than in those without. Con-clusion: sICAM-1 is closely correlated with clinical manifestation of ACI.

Different expression pattern of serum soluble intercellular adhesion molecules-1 and neutrophilic expression of CD18 in patients with diabetic retinopathy

AIM: To investigate the levels of serum soluble intercellular adhesion molecules-1 (sICAM-1) and neutrophilic expression of CD18 in patients with various stages of diabetic retinopathy and to determine their different expression pattern in the development of diabetic retinopathy(DR). METHODS: Levels of serum sICAM-1 and CD18 on the surface of neutrophile were measured in 41 DR patients, they were classified in three subgroups according to the stage of retinopathy as determined by fund's ophthalmoscopy; 10 control subjects were also studied. sICAM-1 were measured by enzyme-linked immunosorbent assay and CD18 by flow cytometry. RESULTS: The neutrophilic CD18 expression and serum sICAM-1 level were all significantly elevated in all diabetic subgroups compared to control subjects (P <0.01). The differences of CD18 and sICAM-1 among the diabetic subgroups were significant in CD18 but not in sICAM-1. The progression of retinopathy was associated with an increase both in CD18 and in sICAM-1 levels by simple correlation analysis (beta =0.74, P<0.001; beta =0.38, P<0.01, respectively). But stepwise multiple regression analysis revealed that only CD18 Was independent determinant of retinopathy (beta =1.04, P<0.01). CONCLUSION: Our results confirm the contribution of endothelial and neutrophilic activation in the development of DR as indicated by increased levels of CD18 and sICAM-1. However, a direct implication of CD18 and ICAM-1 in the progression of DR can be supported only in the CD18 but not ICAM-1. CD18 and ICAM-1 may play different role in the development of diabetic retinopathy.

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.

AIM: To explain the role of Monocyte chemotactic protein-1 (MCP-1) and soluble adhesion molecules in chronic hepatitis C during the treatment of interferon alpha (IFNα) 2 b and ribavirin (RBV).METHODS: Concentrations of MCP-1, soluble adhesion molecules intercellular adhesion molecule-1 (sICAM-1), sPselectin, interleukin (IL) 6, and ILl0 in serum were estimated in the group of 40 patients with chronic hepatitis C treated with IFNalpha2 b and RBV in 0, 16, 32, 48 wk of the therapy.RESULTS: In chronic hepatitis C, before and during the treatment, the serum levels of MCP-1 and sP-selectin in responders were similar to those of healthy subjects. In nonresponders (NR), MCP-1 increased in the course of IFN(α+RBV treatment, differences were statistically significant as compared to responders. MCP-1 correlated statistically with the activity of periportal inflammation (r= 0.35, P<0.05) but not with staging of liver fibrosis, sICAM-1 positively correlated with inflammatory activity and fibrosis in NR. sP-selectin did not correlate with histological findings in the liver. The MCP-1 correlated with the soluble form of sP-selectin concentrations (r= 6, P<0.001) and with IL-10 level in NR (r = 0.4, P<0.05). There was no correlation observed between the concentration of MCP-1 and sICAM-1, IL-6 during the treatment.CONCLUSION: MCP-1 concentration may be a prognostic marker of the efficacy of IFN+RBV therapy in patients with chronic hepatitis C.

Expression of Intercellular Adhesion Molecule-1 in Immune Response of Inner Ear

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.

Intercellular Adhension Molecule-1 in the Pathogenesis of Heroin-induced Acute Lung Injury in Rats

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.
