Abstract

CORTES, Manuel E; HAUYON, Roberto; GONZALEZ, Fernando  and  VIGIL, Pilar. Evidence of Fractality in a Pattern of Crystallization of Bovine Cervical Mucus Obtained at Oestrus. Int. J. Morphol. [online]. 2012, vol.30, n.4, pp.1461-1465. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022012000400031.

Fractality has emerged as a feature of the organization of some complex natural systems. Several biological secretions show fractal-like patterns for their crystallization phenomena but their presence in crystallizations of bovine cervical mucus (BCM) is yet unknown. In order to assess the fractality of BCM crystallization, samples of this fluid were taken from heifers at oestrus, their crystalline patterns photographed and its morphology analyzed. Among the many images obtained for BCM crystallizations, one of them had a highly symmetrical geometric arrangement, possessing three zones characterized by pine-like, arboriform structures, evidencing a remarkable similarity between them. Moreover, fractal dimensions obtained for these zones were statistically equal when analyzed by using specialized software. In summary, this brief communication shows, for the first time, that a pattern of crystallization of BCM at oestrus possesses a fractal-like organization.

Keywords : Bovine cervical mucus; Cervical mucus crystallization; Fractal dimension; Fractality; Oestrus.
