    Abstract:
    OBJECTIVE: To investigate the interference effects of lymph plasma on endotoxic shock and its mechanism. METHODS: Sixty Wistar male rats were randomly divided into three groups: control group, model group and lymph plasma group. The endotoxic shock model of rats were duplicated by jugular intravenous injection with LPS (15 mg/kg), and after 15 minutes the normal lymph plasma was infused in lymph plasma group rats, which amount of lymph plasma was one fifteenth of whole blood volume. The effects of lymph plasma on the mean arterial pressure (MAP), microcirculation of mesentery near the ileum lower, the numbers of leukocytes adherent to the venular wall, the P-selectin and intercellular adhesion molecule-1 (ICAM-1) in plasma were observed. RESULTS: The normal lymph plasma might be prevent from progressive decreased of MAP, depress the pathologic diameter constriction of mesenteric microvessels, reduce leukocytes adherent to the venular wall, improve blood flow condition of microcirculation, and decrease the level of P-selectin and ICAM-1 in plasma (P < 0.05, P < 0.01). CONCLUSION: A little of normal lymph plasma plays a positive interference effect on microcirculatory dysfunction and hypotension with endotoxic shock induced by LPS challenge. Those mechanisms may be concerned with decreasing the production of cell adhesion molecules.
