Objective To study the effects of urinary kallidinogenase (kallikrein) on focal cerebral blood flow (CBF) following cerebral infarction in rats by laser speckle imaging.Methods Permanent middle cerebral artery occlusion (MCAO) was induced in male Sprague-Dawley rats by the intraluminal filament technique.Laser speckle imaging was used to measure CBF in the ischemic cortical area and middle cerebral artery territory.The brain was stained with 2,3,5-triphenyltetrazolium chloride (TTC) to determine the infarct size.Neurological deficit score was measured.Results CBF increased in both hemispheric cortical area and MCA territory on the first and second days following urinary kallikrein administration at high dose but not at low dose.Larger blood vessel diameter and increased blood flow velocity were noticed in the high dose group in some arteries when compared to the low dose group and normal saline control group.At 36 h after cerebral ischemia,the brain infarct size was 10.14% ±3.02% ,25.99% ±3.90% and 27.10% ±3.32% in high, low dose and normal saline control groups,respectively.The infarct size was significantly smaller in the high ( F = 61.14, P<0.01 ) but not low dose group when compared to the normal saline control group.The neurological deficit was milder in the high dose group but not the other two groups at 4 h after cerebral ischemia; however, there were no differences among the groups at 36 h after MCAO.Conclusions Urinary kallidinogenase can reduce cerebral infarction volume and neurological deficit in rats following focal cerebral ischemia.These effects may be attributed to enhanced collateral circulation and improved CBF in the hemispheric cortical area and MCA territory.

Objective To indentify the gene expression on different fractionated radiation regimens with the same total radiation dose in xenografts with human lung adenocareinoma. Methods Forty-eight BALB/c-nu mice, implanted with human lung adenocarcinoma (Anip973), were randomized into 4 groups: normal control greup,60 Gy in 30 fractions conventional radiation group (2 Gy group) ,60 Gy in 10 fractions hypofractionated radiation group (6 Gy group) ,60 Gy in 6 fractions hypofractionaed radiation group (10 Gy group). Gene alterations were investigated with the microchip analytical procedures covering the entire genome. Genes with significantly different expression were further validated by the quantitative real-time polymerase chain reaction (RT-PCR). Results Compared to the 2 Gy group, the expression of the genes related with the cell growth inhibition and apoptesis was increased, while the genes related with the cell proliferation, anti-apoptosis and DNA damage repair were decreased in the 6 Gy and 10 Gy groups. Confirmed by RT-PCR, c-myc gene was distinctly suppressed in the 6 Gy group (2. 9%) comparing with 2 Gy (5.6%) group and 10 Gy (4.8%) group (P=0. 000,P=0. 002) , and was slightly suppressed in the 10 Gy group comparing with 2 Gy group (P = 0. 069). Conclusions In the BALB/c-nu mice implanted with human lung adenocarcinoma, the hypofractionated radiation regimens clearly inhibit the tumor growth more than conventional fractionation group, though with the same total dose. The 6 Gy group seem to be more effective than 10 Gy group in the inhibition of tumor growth.
