Fatty Tissue in Starved Lambs a Histoquantitative and Statistical Study
Fettvävnaden hos svultna lamm, en histokvantitativ och statistisk undersökning
Acta Veterinaria Scandinavica volume 13, pages 340–347 (1972)
Abstract
The kidney fat was histologically examined of 27 spontaneously dead lambs of which 14 had starved. The lambs were born with mature fat, but in young animals a starvation period of more than 24 hrs. reduced the fat tissues and changed its cells towards the embryonal type built up of preadipocytes. These cells were smaller than the mature fat cells. Nucleus was large, round and situated in the centre of the cell. The slight eosinophilic, strongly diminished cytoplasm was some granulated and had some small fat droplets. The starvation changes of fat cells did not depend on the weight of animals or on the age of lambs less than two weeks.
Sammanfattning
Histologiskt undersöktes njurfett från 27 självdöda lamm, av vilka 14 hade svultit. Lammen föddes med füllt utvecklad fettvävnad. Hos unga djur reducerade en svältperiod på 24 timmar stärkt fettvävnadens mängd och gav den ett histologiskt utseende av embryonalt fett, som var uppbyggt av preadipocyter. Dessa celler var mindre än mogna fettceller. Kärnan var stor och rund och var belägen centralt i cellen. Den svagt eosinofila, starkt förmindskade cytoplasman var något granulerad och visade några små fettdroppar. Hos lamm under 2 veckor var fettcellernas svältförändringar inte beroende på djurets vikt eller ålder.
