Topography, morphology, vascularization and inervation of the abdominal organs in the mole rat (Spalax leucodon)

Abstract

Data on morphology, topography, vascularization and innervation of the abdominal cavity organs of the mole rat (Spalax leucodon) published in the reference literature are scarce, and therefore we have decided to study abdominal cavity, topography, morphology, vascularization and innervation of the abdominal portion of the esophagus, stomach, small intestine (duodenum, jejunum and ileum), large intestine (cecum, colon and rectum), liver and its bile ducts, spleen, pancreas and kidneys. Topography and branches of the abdominal aorta, topography and tributaries of the caudal vena cava as well as extrahepatic veins of the portal system were studied as well. The results of our study were supplemented by description of the histological structure of the abdominal portion of the esophagus, stomach, small intestine, large intestine, liver, spleen, pancreas, kidneys, abdominal aorta and caudal vena cava. Quantitative analysis of the wall of the abdominal aorta and all parts of the colon was perfomed linear measurements and stereological measurement using test system M42. Abdominal cavity organs of the mole rat were used as material for investigation both as fresh and preserved preparations from the collection of the Department of Anatomy of the Faculty of Veterinary Medicine in Belgrade. Mole rats were traped on the area of south Banat in the village of Šušara near Uljma (Deliblatska peščara). Since mole rat is protected by law in Republic of Serbia as natural rarities, the approvals of the Ethics Committee and Dean,s of the Faculty of Veterinary Medicine in Belgrade as and Ministry of Environmental Protection of the Republic of Serbia were obtained for provision of 10 mole rats from their natural habitats...

U relevantnoj literaturi ima malo podataka o topografiji, morfologiji, mikroskopskoj građi, vaskularizaciji i inervaciji organa trbušne duplje slepog kučeta (Spalax leucodon), pa smo zato odlučili da ispitamo trbušnu duplju, topografiju, morfologiju, vaskularizaciju i inervaciju trbušnog dela jednjaka (Pars abdominalis), želuca (Ventriculus), tankog creva (dvanaestopalačnog creva-Duodenum, praznog creva-Jejunum i vitog creva-Ileum), debelog creva (slepog creva-Cecum, kolona-Colon i pravog creva-Rectum), jetre (Hepar) i žučne kanale, slezine (Lien), gušterače (Pancreas) i bubrega (Ren). Ispitivali smo i topografiju i granjanje trbušne aorte (Aorta abdominalis), topografiju i pritoke kaudalne šuplje vene (V. cava caudalis) i vene ekstrahepatičnog dela portalnog krvotoka jetre. Rezultate našeg ispitivanja upotpunili smo opisom histološke građe trbušnog dela jednjaka, želuca, tankog creva, debelog creva, jetre, slezine, gušterače, bubrega, trbušne aorte i kaudalne šuplje vene. Kvantitativna analiza zida trbušne aorte i kolona vršena je linearnim i stereološkim merenjima pomoću mnogonamenskog test sistema M42. Kao material za izučavanje koristili smo organe trbušne duplje slepog kučeta (Spalax leucodon) sveže i konzervisane preparate iz kolekcije Katedre za anatomiju Fakulteta veterinarske medicine u Beogradu. Slepi kučići hvatani su na terenu Južnog Banata i to u mestu Šušara kod Uljme (Deliblatska peščara). Obzirom da je u Republici Srbiji slepo kuče zaštićeno zakonom kao prirodna retkost, dobili smo odobrenje Etičkog komiteta Fakulteta veterinarske medicine u Beogradu, dekana Fakulteta veterinarske medicine u Beogradu i Ministarstva zaštite životne sredine Republike Srbije za nabavku deset slepih kučića iz prirode. Za ispitivanje koristili smo anatomske, histološke, morfometrijske i stereološke metode rada. Uz obaveznu anesteziju primenom preparata ketamina (Ketamidor 10%) uz premedikaciju Ksilazinom, životinje su bile žrtvovane. Za morfološko ispitivanje preparati su posmatrani golim okom ili pod stonom lupom, uvećanje 1,75x...
