Morphometric analysis of the cellular composition of the ovine corpus luteum.
An electron microscopical, morphometric study has been made of the cellular and non-cellular composition of the ovine corpus luteum fixed by perfusion, together with an estimate of total cell numbersExpand

The rate of ovarian and utero-placental blood flow through vessels of less than 25 mum diameter was examined with radioactive microspheres in 5 non-pregnant rats and 19 rats at Day 22 of pregnancy.Expand

Embryo survival, and fetal and placental growth following elevation of maternal estradiol blood concentrations in the rat.
High doses of estrogens cause embryonic mortality, and fetal and placental growth retardation in rats. This study addresses the physiological relevance of such findings. Estradiol benzoate (EB), byExpand

Relationships between fetal weight, placental weight and maternal placental circulation in the rabbit at different stages of gestation.
Fetal weights, placental weights, myometrial, vaginal and maternal placental blood flows (estimated with radioactive micro\x=req-\ spheres) were measured in forty-one rabbits at 16, 20, 24 or 28 daysExpand

Fetal and placental weight relationships in the albino rat near term.
The relationship of fetal weight to placental weight was examined in 34 albino rats on day 22 of gestation. The influence of maternal weight, fetal position and the number of fetuses in the litterExpand

Quantitative ultrastructural characteristics relating to transport between luteal cell cytoplasm and blood in the corpus luteum of the pregnant rat.
The synthesis and secretion of progesterone by the corpus luteum (CL) may be limited or controlled by transport mechanisms operating between circulating blood and luteal cell cytoplasm. To examineExpand

Rate of blood flow and growth of the corpora lutea of pregnancy and of previous cycles throughout pregnancy in the rat.
The rate and distribution of ovarian blood flow was measured with radioactive microspheres in nulliparous rats at Days 4, 7, 10, 13, 16 and 22 of gestation; term is Day 23. Ovaries were dissectedExpand

Changes in ovarian blood flow and secretion of progesterone and 20 alpha-hydroxypregn-4-en-3-one on day 16 and the morning and afternoon of day 22 of pregnancy in the rat.
During late pregnancy in rats, ovarian secretion of progesterone decreases and that of its reduced metabolite, 20 alpha-hydroxypregn-4-en-3-one (20 alpha-OHP), increases. The present study wasExpand

Mean fetal and placental weights were, respectively, 0.018 and 0.051 g on Day 13 and 0.376 and 0.250 g on Day 17. Fetal and placental weights within litters were weakly correlated on Day 13 (r =Expand

Effects of maternal progesterone supplementation of fetal, placental and corpus luteal weights in the rat.
Progesterone, at five times normal 24 h endogenous production rates, was administered daily to 37 rats over Days 2 to 10, 11 to 17 or 2 to 21 of gestation: term is Day 23. Peanut oil, the vehicle,Expand
