    Croatian abstract

    Dok su limfne žile u nekim endokrinim žlijezdama dobro istražene, podaci u dostupnoj literaturi o spomenutim strukturama ljudskih epitelnih tjelešaca često su oprečni i manjkavi. Stoga je cilj ovoga rada bio histomorfološki istražiti postoje li limfne žile u epitelnim tjelešcima čovjeka nakon rođenja i ako postoje, ovisi li njihova prisutnost o životnoj dobi i o spolu. Istraženo je 44 epitelnih tjelešaca osoba oba spola, od 4. do 90. godine života. Žlijezde su podijeljene u tri dobne skupine. Prva i druga dobna skupina pokazuju sličnu morfološku građu parenhima u kojem su prevladavale svijetle glavne stanice, dok je učestalost limfnih žila manja u drugoj skupini. Za razliku od prethodnih skupina u žljezdanom parenhimu treće dobne skupine prevladavale su tamne glavne stanice, a limfne žile nisu pronađene ni u jednoj istraženoj žlijezdi. Učestalost limfnih žila epitelnih tjelešaca gotovo je jednaka u oba spola. Histomorfološka pojava limfnih žila podudara se s prisutnošću svijetlih endokrinih stanica, što dopušta pretpostaviti da su i limfne žile jedan od znakova funkcionalne aktivnosti epitelnih tjelešaca čovjeka.

    English abstract

    Whereas lymph vessels in some endocrine glands have been thoroughly investigated, data on these vessels in human parathyroid glands are often contradictory and deficient in available literature. Therefore, the aim of this study was to histomorphologically investigate whether lymph vessels could be found in human parathyroid glands postnatally and, if so, whether their presence was age- and gender-dependent. A total of 44 parathyroid glands from subjects of both genders, aged 4-90 years, were studied. The glands were divided into three groups. Those from the 1st and the 2nd age group demonstrated similar morphological structure of parenchyma with predominant chief cells with pale-staining cytoplasm, while the frequency of lymph vessels was lower in the 2nd group. Unlike in these groups, chief cells with dark- staining cytoplasm predominated in the glandular parenchyma of the 3rd age group where lymph vessels were not found in any of the examined glands. The frequency of lymph vessels in parathyroid glands was almost the same for both genders. Histomorphologic occurrence of lymph vessels coincided with the presence of endocrine cells with pale-staining cytoplasm, which allowed the assumption that lymph vessels were also one of the signs of functional activity of human parathyroid glands.
