Objective To observe the changes of behaviour, NOS neurons, Nissl bodies and ultrastructure after L-NNA treatment of acute spinal cord injury in rats. Methods Using movement and incline plane(IP)score to observe hindlimbs movement of rats with spinal cord injury; NADPHd histochemistry, Nissl methed and electron microscopy were used for observation of changes of neuronal NOS, Nissl bodies and ultrastructure of three groups(normal control group, saline solution(NS)control group and L-NNA group). Re- sults 1. Changes of behaviour: Hindlimbs movement and IP score in L-NNA group is more potent than that in NS group(P

OBJECTIVETo analyze the detection results for the patients with lymphoproliferative disease(LPD) accompanied with the infection of EB.

METHODSThe EBV specific antibody, serum cytokine, EBV DNA copy number in peripheral blood mononuclear cells (PBMNC) of 70 LPD patients and 70 healthy volunteers were analyzed and compared.

RESULTSThe positive rates of VCA-IgG and VCA-IgM were not significantly different in two groups (P>0.05); The positive rate of EA-IgG in the PLD patient group was higher than that in the control group (P<0.05); the levels of IL-18 and IFN-γ were not significantly different between the 2 group (P>0.05); the EBV DNA copy number in PBMNC of the PLD patient group was higher than that in the control group (P<0.05).

CONCLUSIONThe patients with LPD show the active infection of EBV, that is the main reason for the abnormal function of lymphatic system in the patients with LPD. The active infection of EBV maybe involve in PLD pathogenesis.
