Effect of the oestral cycle on respiratory mechanics in the rat

Acta Physiologica, 2007
AbstractAim:  To assess the effect of the oestral cycle on the respiratory mechanics of the rat.Methods:  We measured the main mechanical respiratory parameters, namely respiratory system and lung resistances and compliances, by the end‐inflation occlusion method on two populations of female rats, during proestrous–oestrous and metaoestrous–diestrous ...

Modifications des cellules gonadotropes de la pr�hypophyse chez la ratte inject�e de testost�rone au cours du cycle oestral

Zeitschrift f�r Zellforschung und mikroskopische Anatomie, 1973
4-day cyclic adult female Wistar rats were injected subcutaneously with testosterone propionate on diestrus 1 at 16:00 and on diestrus 2 at 10:00 respectively. Non-injected females served as controls. Autopsy was performed on diestrus 2 at 23:00, and on proestrus at 14:00 and 17:00 respectively. The blue Alcian-PAS staining was used to evidence FSH (β)

Onset of puberty and regularity of oestral cycles in ewe lambs of four breeds under high-altitude conditions in a non-seasonal country

Tropical Animal Health and Production, 2020
Twenty-four Colombian Creole, Romney Marsh, Hampshire and Corriedale ewes raised under high-altitude conditions in a non-seasonal country were used to determine and to characterize the onset of puberty and of regularity ovarian function since the age of 3months.
