But the message doesn't seem to transmit during diestrus
, when levels of the hormone progesterone are high.
The longer estrous cycle resulted from a longer diestrus
phase, and shorter estrus and proestrus phases of the two experimental groups, as compared with the control group (p < 0.
Lower doses of DC seed extract (3-100 mg/kg BW) arrested the oestrous cycle and prolonged diestrus
, while higher doses (150-250 mg/kg BW) prolonged the oestrous stage of the cycle.
Recent experiments in our laboratory have demonstrated that TGase1 is expressed in vaginal epithelium of mature mice during the stages of the estrous cycle when estrogen levels are high, namely, estrus, metestrus, and diestrus
It occurs at the end of diestrus
and is characterized by hyperplasia of the mammary glands, lactation, and behavior changes.
We observed that the RHAMM immunoreactivity of uterine epithelial cells and subepithelial cells increased in proestrus compared with estrus and diestrus
cycles (Table 1).
With maturation of the CL, concentrations of P4 in peripheral blood are maximum in diestrus
and, in cyclic females, PGF-induced luteolysis occurs in late diestrus
(d 15-16 for sheep; d 16-18 for cattle and goats).
The rat estrous cycle (estrus, diestrus
2, and proestrus) usually lasts about 4 days, in both control and PCO rats (16).
Mice with 3 consecutive days in either diestrus
or estrus were considered to have abnormal cycles.
ABSTRACT : This study was undertaken to investigate the distribution of major histocompatibility complex class II positive (MHC II+) (HLA-DP-like) cells in the cow uterus (cervix, corpus and cornu uteri) and to compare these cells between the estrus and diestrus
phases of the estrous cycle.
In a rat model, chronic EGME exposure suppressed cyclicity and prolonged diestrus
, providing further in vivo evidence consistent with attenuation of estrogenic responsiveness (Davis et al.
05) during metestrus (d 2 to d 7) but not during diestrus
(d 7 to d 12).
smears contained numerous leukocytes, Schorr cells, increasing basophilic epithelial cells, and mucous.
We classified the vaginal smears as described by Everett (1989) and defined extended estrus as exhibiting cornified cells with no leukocytes for [greater than or equal to] 3 days and extended diestrus
as the presence of leukocytes for [greater than or equal to] 4 days (Cooper et al.
Second estrus was defined as the day on which a smear indicating estrus fell within a run of smears clearly showing the correct cyclic sequence of proestrus, estrus, metestrus, and diestrus
