1The simulation of ultrasonic beams with a Gaussian beam equivalent point source model显示文摘点来源和 Gaussian 横梁作为基本积木经常被使用开发超声的横梁模型。两个这些模型有限制他们的有效性的不同软弱。这里,我们将证明一个人能开发移开那些软弱并且把点来源模型的精确性和通用性与许多速度相结合的一个 Gaussian 横梁等价物点来源(GBEPS ) 模型并且行为优良 Gaussian 横梁的自然当模特儿。我们将在模仿从超声的分阶段执行的数组产生的横梁表明这个新 GBEPS 模型的效率和通用性,用象每数组的元素的一根 Gaussian 横梁一样的同样多。甚至当实质的横梁集中或驾驶在数组是在场的时或在数组横梁通过一个接口被播送的地方,一个单个元素 GBEPS 模型将被显示象一个点来源模型一样精确。同时, GBEPS 模型将被显示比点来源模型快几个数量级。SCHMERR L W HUANG R SEDOV A 2010Chinese Journal of Acoustics2010,29,2:6
2Intestinal injury can be reduced by intra-arterial postischemic perfusion with hypertonic saline显示文摘AIM:To investigate the effect of local intestinal perfusion with hypertonic saline(HTS) on intestinal ischemia-reperfusion injury(IRI) in bothex vivo andin vivo rat models.METHODS:All experiments were performed on male Wistar rats anesthetized with pentobarbital sodium given intraperitoneally at a dose of 60 mg/kg.Ex vivo vascularly perfused rat intestine was subjected to 60-min ischemia and either 30-min reperfusion with isotonic buffer(controls),or 5 min with HTS of 365 or 415 mOsm/L osmolarity(HTS 365mOsm or HTS 415mOsm,respectively) followed by 25-min reperfusion with isotonic buffer.The vascular intestinal perfusate flow(IPF) rate was determined by collection of the effluent from the portal vein in a calibrated tube.Spontaneous intestinal contraction rate was monitored throughout.Irreversible intestinal injury or area of necrosis(AN) was evaluated histochemically using 2.3.5-triphenyltetrazolium chloride staining.In vivo,30-min ischemia was followed by either 30-min blood perfusion or 5-min reperfusion with HTS 365mOsm through the superior mesenteric artery(SMA) followed by 25-min blood perfusion.Arterial blood pressure(BP) was measured in the common carotid artery using a miniature pressure transducer.Histological injury was evaluated in both preparations using the Chui score.RESULTS:Ex vivo,intestinal IRI resulted in a reduction in the IPF rate during reperfusion(P < 0.05 vs sham).The postischemic recovery of the IPF rate did not differ between the controls and the HTS 365mOsm group.In the HTS 415mOsm group,postischemic IPF rates were lower than in the controls and the HTS 365mOsm group(P < 0.05).The intestinal contraction rate was similar at baseline in all groups.An increase in this parameter was observed during the first 10 min of reperfusion in the control group as compared to the sham-treated group,but no such increase was seen in the HTS 365mOsm group.In controls,AN averaged 14.8% ± 5.07% of the total tissue volume.Administration of HTS 365mOsm for 5 min after 60-min ischemia resulted in decrease in AN(5.1% ± 1.20% vs controls,P < 0.01).However,perfusion of the intestine with the HTS of greater osmolarity(HTS 415mOsm) failed to protect the intestine from irreversible injury.The Chiu score was lower in the HTS 365mOsm group in comparison with controls(2.4 ± 0.54 vs 3.2 ± 0.44,P = 0.042),while intestinal perfusion with HTS 415mOsm failed to improve the Chiu score.Intestinal reperfusion with HTS 365mOsm in the in vivo series secured rapid recovery of BP after its transient fall,whereas in the controls no recovery was seen.The Chiu score was lower in the HTS 365mOsm group vs controls(3.1 ± 0.26 and 3.8 ± 0.22,P = 0.0079 respectively,),although the magnitude of the effect was lower than in the ex vivo series.CONCLUSION:Brief intestinal postischemic perfusion with HTS 365mOsm through the SMA followed by blood flow restoration is a protective procedure that could be used for the prevention of intestinal IRI.Oleg Kornyushin Michael Galagudza Anna Kotslova Gelfia Nutfullina Nina Shved Alexey Nevorotin Valeriy Sedov Timur Vlasov 2013World Journal of Gastroenterology2013,19,2:4
