Changes and its significance of neuron-specific enolase and myelin basic protein in serum after seizure of rats with temporal epilepsy / 临床神经病学杂志

Objective To explore the dynamic changes of neuron-specific enolase (NSE) and myelin basic protein (MBP) in serum of rats with temporal epilepsy (EP) induced by kainic acid (KA) and to judge the degree of injury of brain neuron and nerve myelin after seizure.Methods KA was injected into rat's hippocampus by stereotactic operation to establish an animal model of temporal EP.The levels of NSE and MBP in serum of rats with temporal EP were measured at the time 3 h,6 h,12 h,24 h,48 h and 72 h after seizure.Results The level of NSE in serum increased gradually and reached its peak at 24 h after seizure, as well as MBP at 72 h.Conclusions There are the nerve cell damage and necrosis after seizure in rats with temporal EP, then brain white matter nerve myelin appear to damage.

Expression of ROR?t in pulmonary tissue of asthmatic mice and its relationship to airway inflammation / 中国免疫学杂志

Objective:To explore the expression of ROR?t in pulmonary tissue of asthmatic mice and to investigate the association between the expression of ROR?t and the airway inflammation.Methods:Thirty female BLAB/c mice were randomly divided into the control group,asthmatic group and dexamethasone (Dex)-treated group.The asthma model was induced by classical method with ovalbumin(OVA).The concentration of IL-17 in bronchoalveolar lavage fluid (BALF) and serum was measured by enzyme-linked immunosorbent assay(ELISA).Airway inflammation was evaluated by HE staining.The expressions of IL-17,ROR?t mRNA and protein was measured by reverse transcription-polymerase chain reaction(RT-PCR) and Western blot respectively.Results:The level of IL-17,ROR?t mRNA and protein of asthmatic group was significantly higher than those of control group and Dexamethasone treated group (P

Effect of recombinant MIF on lung fibroblast proliferation and collagen synthesis in vitro / 中国病理生理杂志

AIM: To investigate the influence and mechanism of recombinant macrophage migration inhibitory factor(rMIF) on fibroblasts.METHODS: MRC-5 fibroblasts were divided into two groups: the treated group was treated with rMIF(25-100 ?g/L,12 h,24 h or 48 h) and the control was non-rMIF treatment.The activity of proliferation in both groups was investigated and compared by CCK-8 means.Synthesis of collagen in the culture supernatants was detected by the hydroxyproline.The expression of collagen type I mRNA was examined using RT-PCR analysis.The level of collagen type I protein induced by rMIF was quantified by Western blotting.RESULTS: The production of proliferation ratio of fibroblasts treated with 50 ?g/L and 100 ?g/L rMIF at 24 h or 48 h were increased obviously(P
