Objective To investigate the effects of lipoxin A4 (LXA4) on the inflammatory response to focal cerebral ischemia-reperfusion(I/R) inmy in rats.Methods Fifty-six healthy male SD rats weighing 200-250 g were randomly divided into 3 groups:group Ⅰ sham operation(group S,n=8);group Ⅱ cerebral I/R(n=24)and group Ⅲ lipoxin A4+I/R(group LXA4,n=24).Right mid-cerebral artery was occluded for 2 h by inserting cranially a nylon thread with rounded tip into internal carotid artery.LXA4 0.03 nmol/5 μl was injected into cerebral ventricle at 5 min after cerebral ischemia.Neurological deficit was scored at 24 h of reperfusion.Then four animals in each group were killed and their brains were removed for microscopic examination and expression of MPO at 24 h of reperfusion.Meantime,content of IL-1β,TNF-α,TGF-β1,and IL-10 in the brain tissue were measured at 1,6,12,24 and 48 h of reperfusion by ELISA.Glial cell activity was examined at 24 h of reperfusion by immuno-histochemistry.Results Intra-cerebroventricular administrated LXA4 0.03 nmol/5 μl provided mild neuroprotection against focal cerebral I/R injury,improved neurological deficits,and reduced morphological brain damages and PMN infiltration.LXA4 also decreased the content of TNF-α and IL-1β,and increased the content of IL-10 and TGF-β1.The numbers of activated astroglia and microglia were decreased in group LXA4 compared with group I/R.Conclusion LXA4 protects the brain against I/R injury by inhibiting inflammatory response.

BACKGROUND:Naringin can increase bonemorphogeneticprotein 2 gene expression and promote the proliferation and differentiation of multipotential stem cel line. In vitro cel experiment indicates that naringin can suppress osteoclast formation and anti-osteoporosis activity.
OBJECTIVE:To prepare a mouse calvarial bone culture model containing naringin and to observe the effect of naringin with different concentrations on the formation and function of osteoclasts.
METHODS:Calvarial bone was dissected out aseptical y from the 4-day-old Sprague Dawley mice, and cultured in the culture medium containing 0, 1, 10 and 100 mg/L naringin. The effects of naringin on the number of tartrate-resistant acid phosphatase-positive osteoclast marker enzyme in calvarial bone and the concentration of calcium in the culture medium were detected after cultured for 1, 3, 7 and 10 days.
RESULTS AND CONCLUSION:After cultured for 1 day, the number of tartrate-resistant acid phosphatase-positive cel s in calvarial bones and the calcium concentration in the culture medium had no difference between the groups. After cultured for 3 and 7 days, the number of tartrate-resistant acid phosphatase-positive cel s was decreased and the calcium concentration was increased with the increasing concentration of naringin. At 10 days after culturing, this trend was most obvious. It showed that naringin could affect the number and function of tartrate-resistant acid phosphatase-positive cel s in calvarial bones, and this effect showed a significant time-and dose-depend manner. The results show that naringin can not only promote the proliferation of osteroclasts, but also reduce the differentiation of osteoclasts or accelerate the apoptosis.
