L. Losinno et al., UTERINE AND OVIDUCTAL INFLAMMATION ANOVULATORY MARES WITH ULTRASONOGRAPHICALLY-DETECTED INTRAUTERINE LUMINAL FLUID, Theriogenology, 48(8), 1997, pp. 1361-1368
Intrauterine luminal fluid in diestrous mares has been associated with
uterine inflammation. The objectives of this study were to measure th
e incidence of intrauterine luminal fluid in anovulatory mares, and to
determine the association of uterine fluid with uterine and oviductal
inflammation. Intrauterine luminal fluid was detected ultrasonographi
cally in 18.8% (19/101) of anovulatory mares. Thirteen anovulatory mar
es with uterine fluid and 10 anovulatory mares without uterine fluid w
ere subsequently re-examined, and their uteri and oviducts were evalua
ted histologically for inflammation. Only 43.5% (10/23) of the mares m
aintained a fluid (4/10) or non fluid (6/13) condition at their second
examination, indicating that intrauterine luminal fluid occurred dyna
mically in these anovulatory mares. Moderate to severe uterine inflamm
ation was not related with the detection of uterine fluid. A greater i
ncidence of moderate to severe uterine inflammation was not detected i
n mares with 2 detections of fluid in contrast to mares with 1 or no d
etections of fluid. Regardless of the occurrence of uterine fluid or t
he amount of uterine inflammation, oviductal inflammation was minimal
in the anovulatory mares. (C) 1997 by Elsevier Science Inc.
