Renal medullary lymphatics: microradiographic, light, and electron microscopic studies in pigs. 1985

Although renal cortical lymphatics have been extensively studied, the existence of renal medullary lymphatics has not been well documented. We studied renal microlymphatics in pig kidneys by retrograde ureteral injection of barium-sulfate-gelatin-saline mixture. Lymphatics filled as a result of forniceal rupture and interstitial extravasation. Microradiographs were correlated with histology and electron microscopy. We traced renal microlymphatic vessels from the arcuate level not only into the cortex but also into the pyramidal region, and therefore concluded that medullary lymphatics existed.

UI	MeSH Term	Description	Entries
D007679	Kidney Medulla	The internal portion of the kidney, consisting of striated conical masses, the renal pyramids, whose bases are adjacent to the cortex and whose apices form prominent papillae projecting into the lumen of the minor calyces.

D008208	Lymphatic System	A system of organs and tissues that process and transport immune cells and LYMPH.	Lymphatic Systems
D008220	Lymphography	Radiographic study of the lymphatic system following injection of dye or contrast medium.	Lymphangiography,Lymphangiographies,Lymphographies
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D013552	Swine	Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).	Phacochoerus,Pigs,Suidae,Warthogs,Wart Hogs,Hog, Wart,Hogs, Wart,Wart Hog
