Histomorfometria do corno uterino de gatas (Felis Catus) submetidas à ovariosalpingohisterectomia

Histomorphometric data were obtained from cats uterine horns: either nulliparous (n = 6), primiparous (n = 6), multiparous (n = 6) and treated with contraceptive (n = 6). The material was collected after surgery, fixed in paraformaldehyde and embedded in paraplast® resin to be sliced in a microtome. The obtained sections were stained with hematoxylin - eosin and measured under a light microscope: uterine wall total thickness (μm), endometrium total height, endometrial glands diameter and glandular epithelia height, total myometrium, internal and external myometrium and vascular layer thickness. It was concluded that: 1 - contraceptive use and number of pregnancies altered the uterine structure, 2 - one pregnancy does not appear to affect the uterine lining structures as occurs in multiparous cats, 3 - there was no variation on the evaluated structures between nulliparous and primiparous cats except for inner myometrium, 4 - the total myometrium hight and the endometrium hight showed similar variations except for the contraceptive treated cats group, 5 - the outer myometrium showed marked changes in the treated cats, 6 - the less marked morphological variations were for the endometrial glands diameter and glandular epithelium hight, 7 - the presence of dilated endometrial glands was found only in treated cats.

Intriguing thigmonastic (sensitive) stamens in the Plains Prickly Pear Opuntia polyacantha (Cactaceae)

The movement of sensitive stamens in flowers of the Plains Prickly Pear (Opuntia polyacantha) is described in detail along with the external and internal filament anatomy. The goals of this investigation were: (1) to provide a synthesis of floral phenology and determine whether this rather unique stamen movement is nastic or a tropism and (2) to conduct macro- and micro-morphological analyses of filaments to determine if there are anatomical traits associated with this movement. To better understand the internal and external structure in sensitive filaments of O. polyacantha, we performed comparative anatomical analyses in two additional species from the Opuntioideae with stamens lacking such sensitivity. The consistent unidirectional movement of stamens, independent of the area stimulated, indicates a thigmonastic response. This movement serves multiple purposes, from enhancing pollen presentation to facilitating cross-pollination, protecting pollen and preventing insects from robbing pollen. Anatomically, the sensitive and non-sensitive filaments exhibit different tissue organization. Cuticle thickness, presence of capsular structures, two layers of curved cells, and more and larger intercellular spaces are characteristic of sensitive filaments. A thin unicellular epidermal layer is characteristic in sensitive filaments versus 2-3 epidermal layers in non-sensitive filaments. Another striking feature in sensitive filaments is the presence of papillae and capsular structures. We believe that these elements are related to water mobility with subsequent contraction during the thigmonastic response. Capsular structures might have a role in fluid mobility according to the stimulus of the filaments. We hypothesize that the thigmonastic response is controlled by cells with elastic properties, as evidenced by the plasmolyzed curved and contracted cells in the filaments and the fact that the movement is activated by changes in cell turgor followed by contraction as a result of plasmolysis. © 2013 Elsevier GmbH.
