Example Sentences:

Radicle
Definition:
(n.) The rudimentary stem of a plant which supports the cotyledons in the seed, and from which the root is developed downward; the stem of the embryo; the caulicle.
(n.) A rootlet; a radicel.
Example Sentences:
(1) Although its etiology is still undetermined, the liver pathology is characterized by occlusive changes of the intrahepatic portal radicles, portal and periportal fibrosis, irregularly distributed parenchyma atrophies and absent of regeneration nodules.
(2) The common hepatic duct opened directly into the mass, and the intrahepatic radicles were dilated.
(3) In order to provide drainage, the catheter should be advanced under fluoroscopic control into one of the major radicles ore preferably into the distal common duct beyond the point of obstruction.
(4) There were numerous retained gallstones in biliary radicles of the right hepatic duct; attempts to dislodge these by saline flushing failed.
(5) Special phenomena related to the small caliber of the needle include duct filling from "invisible" radicles, perivenous or periductal dissection of contrast, and pseudolesions in an incompletely decompressed stagnant bile column.
(6) In the group with Budd-Chiari's syndrome (BCS), in addition to the involvement of the large veins, thrombosis was observed in the small hepatic vein radicles in five out of six cases with myeloproliferative related disorders.
(7) In contrast to previous reports of hepatopathy after irradiation injury, histologic sections of the liver did not demonstrate occlusion of the central veins, but rather a diffuse obliteration of intrahepatic portal venous radicles.
(8) Cholangiographic features were the most characteristic and included irregular narrowing and segmental dilatation of the biliary radicles giving them a beaded appearance.
(9) The changes in hepatic venous radicles are characterized by irregular sclerosis, which seems to contribute significantly toward postsinusoidal block in advanced cases.
