KOSIF, Rengin; AKTA, Gülhan  e  OZTEKIN, Aynure. Microscopic Examination of Placenta of Rats Prenatally Exposed to Aloe barbadensis: A Preliminary Study. Int. J. Morphol. [online]. 2008, vol.26, n.2, pp.275-281. ISSN 0717-9502.

Aloe barbadensis is the most widely used both commercially and therapeutic properties. It has been used for an array of ailments since ancient times as a medicinal plant. There are more than 360 different species of Aloe. Its products have been used in health foods for medical and preservative purposes. The objective of this study was to search the effects of Aloe barbadensis on the rat's placenta. Gel form of Aloe barbadensis is used in the study. It is commercial, preserved but otherwise untreated form of Aloe Barbadensis gel capsul. Female Wistar Albino rats were divided into three groups. Placenta specimens from each groups were processed for the microscopic examination. Trophoblastic giant cells and spongiotrophoblasts were decreased in number after Aloe barbadensis: trophoblastic giant cells which showed degenerative changes. The nuclei of these giant cells were going degeneration characterized by pyknosis and bizarrely shaped. Extracellular matrix production around the cells was increased, thicker and more irregular basal membrane like formation around the cells. Decreased and ab normal vessel formation in labyrinth área was clear and reduced functional capacity of the trophoblastic barier. The study shows that, in the presence of Aloe barbadensis, relevant alterations associated with a possible compensatory adjustment to maintain adequate metabolic exchange take place in the structure of placenta. Our results also demonstrated that the exposure to Aloe barbadensis during pregnancy not led to fetal growth retardation, fetal death, abortion or teratogenic effect.
