Objective To observe the effect of early intervention on the oligodendrocyte-myelin glycoprotein(OMgp) mRNA expression of brain injury neonatal rats caused by intrauterine infection.Methods 1.Twenty-eight Wistar pregnant rats were randomly divided into 2 groups:lipopolysaccharide(LPS)-treated group and saline control group.Pregnant rats were consecutively injected with LPS (450 ?g?kg-1) or saline on the 18th gestation age.After birth,the placentas were taken out and made HE staining to observe intrauterine infection.2.Thirty neonatal rats in the saline control group and 55 rats in the LPS-treated group were randomly selected which were divided into intervention group (n=25) and no-intervention group (n=25).The second post-natal day (P2) rats in intervention group were treated by early touch and enriched environment.The neonatal rats in the no-intervention group and saline control group were fed in a routine way.Five cases of P1 rats were selected respectively from the LPS-treated group and saline control group,and brain tissue pathological section was made to observe the condition of brain injury.3.Five cases of P1,P3,P7,P28 and P42 rats were selected from the saline control group,intervention group and no-intervention group to detect the OMgp mRNA expression levels by using the real time polymerase chain reaction me-thod.Results 1.There were a great number of neurophilic granulocytes in the placentas in the LPS-treated group.2.Brain tissue pathological of P1 in the saline control group had complete substantia alba structure,ordered disposition and lightly stained clear chromatospherite.While in the LPS-treated group, there existed brain tissue looseness,colloid cell aggregation and oligodendrocyte cytoreduction in the position of substantia alba,callositas and capsula interna.Intraventricular hemorrhage,substantia alba blood vessel dilatation and blood capillary angiorrhexis and hemorrhage could also be found.3.There was a higher increase in OMgp mRNA expressions of brain tissue in the LPS-treated group at P1,P3,P7,P28,P42 than those in the saline control group (Pa

Objective To detect micronuclei (MN) induced by nickel chloride (NiCl2) using a flow cytometry-based method, so as to study the mutagenecity of this chemical. Methods The micronucleated reticulocytes (MN-RET) in peripheral blood of NIH mice exposed to 0.75 mg/kg colchicines (COL), 40.0 mg/kg of cyclophosphamide (CP) and 5.0, 10.0 and 20.0 mg/kg of NiCl2 were detected by a flow cytometry-based method, in which anti-CD71-FITC and PI were used to stain cells and malaria-infected erythrocytes were employed as biological standards of micronuclei to optimize cytometry. Results Although COL or CP induced significant increase in the frequency of MN-RET in peripheral blood, MN formation in peripheral reticulocytes was not significantly affected by exposing to different concentration of NiCl2. Conclusion The results of flow cytometric analysis in the present paper do not support that NiCl2 exposure may induce significant MN-RET increase in peripheral blood in NIH mice.
