Abstract

DEMIRCI, Tuba et al. Toward the First Definition of Taste Rosea in Female Breasts: Histological Analysis. Int. J. Morphol. [online]. 2020, vol.38, n.3, pp.565-569. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022020000300565.

Although various neuropsychochemical theories have been established about why breastfeeding mothers feel hedonic sensation, the underlying neural mechanism has not been adequately clarified. We aimed to investigate if there is hedonic sensation-initiated taste-bud like structures stimulated by sugars in the milk-secreting lactiferous ducts of mammary glands of breastfeeding female rats. In this study, twenty-two female rats were chosen which six of the virgin (n=6), six of pregnant (n=6) and ten of breastfeeding (n=10). We examined lactiferous ducts/nipples of mammary glands of all animals. They were sacrificed following intracardiac formalin injection, and their breast tissues were removed with covering tissues and fixed with 10 % of formalin solution. After current histological procedures, the tissues were examined by light microscope to assess taste-bud like structures, and their numerical densities were calculated by using stereological methods. Results were analyzed statistically. Taste-buds like structures with neuron-like appendages at the apical ends were discovered in lactiferous ducts. The taste rosea numbers were estimated as 3±1/mm3 in virgins, 167±27/mm3 in pregnant and 375±63/mm3 in breastfeeding animals. The taste rosea numbers were greater in breastfeeding rats than those of virgins and pregnant rats. They named as taste rosea resembling flower bucket which has not been mentioned in the literature so far.
