High impact information on Mesenteric Artery, Inferior

• In vitro, CRF injected into the inferior mesenteric artery increased distal colonic myoelectric activity compared with saline injection [6].
• Arteriograms revealed total occlusion of the celiac axis and superior and inferior mesenteric arteries [7].
• CONCLUSIONS: In patients with primary tubal carcinoma, the left para-aortic chain above the level of the inferior mesenteric artery is the most frequently involved [8].
• Angiography of the superior and inferior mesenteric arteries was performed in the two patients with steroid-refractory gut aGVHD, and identical abnormal findings were obtained [9].
• Patients with GI GVHD were treated with infusions of methylprednisolone into the superior and inferior mesenteric arteries [10].

Chemical compound and disease context of Mesenteric Artery, Inferior

• Acetylcholine (ACh) (0.1--1000 microgram) administered into the inferior mesenteric artery to reach the mesenteric ganglion induced a dose-dependent rise in perfusion pressure and this dose-response curve was shifted to the right by C6 or atropine [11].

Biological context of Mesenteric Artery, Inferior

• Frequency- and concentration-dependent isometric contractions were observed in human inferior mesenteric artery and vein mounted rings that were stimulated with either electrical pulses (70 V, 0.5 ms, 2.5-20 Hz) or noradrenaline [12].

Anatomical context of Mesenteric Artery, Inferior

• The effects of the injection of algogenic substances (bradykinin, acetylcholine) into the inferior mesenteric artery were studied at the thoracic level on 47 dorsal horn interneurons responding to cutaneous stimulation [13].
• 4) Afferent units which responded to distension of the colon and to bradykinin were also excited by partial or complete ischaemia of the colon (produced by occlusion of both mesenteric arteries or of only the inferior mesenteric artery) [14].
• Isoproterenol increased (P less than 0.05) blood flow of the axillary artery (+52%), and the superior mesenteric artery (+45%), but not that of the inferior mesenteric artery [15].
• 1. The present study was designed to compare the overflow of sympathetic neurotransmitters of guinea-pig inferior mesenteric artery and mesenteric vein evoked by electrical field stimulation (EFS) with special emphasis on the simultaneous release of ATP and noradrenaline (NA) [16].
• Three-dimensional computed tomography imaging of the inferior mesenteric artery, celiac artery and hepatic artery was performed [17].

Associations of Mesenteric Artery, Inferior with chemical compounds

• Methoxamine caused a dose-related inhibition of colon contractions and a decrease in inferior mesenteric artery (IMA) blood flow [18].
• 2. Endothelium-denuded segments of inferior mesenteric arteries or veins were superfused in a small volume (200 microL)-chamber for EFS and subsequent detection of NA (HPLC- electrochemical detection) and adenine nucleotides and adenosine (HPLC-fluorescence detection) in samples of the superfusate [16].
• Although cyclosporine, steroid pulse therapy, and FK506 proved ineffective, 30 mg of water-soluble prednisolone as administered into each the superior and inferior mesenteric artery with remarkable effects [19].
• Using an isolated buffer-perfused rabbit left colon preparation, 1.0- or 5.0-micrograms doses of PAF were infused into the inferior mesenteric artery [20].
• Measurements were repeated after the injection of 50 mg papaverine into the inferior mesenteric artery [21].

Gene context of Mesenteric Artery, Inferior

• Visceral angiography confirmed occlusion of the celiac, superior, and inferior mesenteric arteries [22].
• Tissue-PA was mainly detected in the endothelial cells, but not in the muscular layer of the inferior mesenteric artery when immunochemical technique was used with polyclonal t-PA antibody [23].
• The inferior vena cava was divided into 3 levels: the area of the bifurcation of the vena cava (level 1), the area between the bifurcation and the inferior mesenteric artery (level 2), and the area between the inferior mesenteric artery and the right ovarian vein (level 3) [24].
• Injection of the structurally related peptides, endothelin-1 and vasoactive intestinal contractor (VIC), into a branch of the superior mesenteric artery in anesthetized cats caused dose-dependent reductions in blood flow in the portal vein and inferior mesenteric artery [25].
• It is commonly held that the caudal mesenteric artery (CaMA, or inferior mesenteric artery in humans) arises in the same manner as the celiac and cranial mesenteric artery (CrMA, or superior mesenteric artery in humans), i.e., from the remodeling of the vitelline system of arteries that surrounds and supports the yolk sac [26].

Analytical, diagnostic and therapeutic context of Mesenteric Artery, Inferior

• The rectal arteries were examined by direct dissection in 12 specimens and after injecting the inferior mesenteric artery with barium sulfate in 20 specimens [27].
• The technique affords a rapid simple approach to selective and superselective catheterization of the celiac, superior mesenteric and inferior mesenteric arteries [28].
