Urinary oestrogen levels in the sow during oestrous cycle and early pregnancy.
were characterized by a rise of the levels associated with oestrus to a well-defined peak followed by a sudden decrease, usually to the lowest levels observed. After conception, the levels of oestrone were not appreciably different from those during the oestrous cycle until at the end of the 3rd week at which time the excretion of oestrone increased. The week of maximal oestrone excretion in th...

متن کاملImmunohistochemical studies on the progesterone receptor (PR) in the sow uterus during the oestrous cycle and in inseminated sows at oestrus and early pregnancy.
Physiological changes in the sow uterus involve the regulation by progesterone and its receptor proteins (PR). Therefore, the aim of the present study was to investigate the localization of PR during different stages of the oestrous cycle and in inseminated sows during early pregnancy by use of immunohistochemistry. Uterine samples were collected from cyclic and inseminated sows at different st...
متن کاملIntracellular relationships of the oestrogen receptor in the rat uterus and hypothalamus during the oestrous cycle.
Simultaneous measurements were made of the specific oestrogen receptor in the nuclear and cytosol fractions prepared from the uterus and hypothalamus of 50--81-day-old female rats undergoing a 4-day oestrous cycle. In the uterus, the content of nuclear receptor fluctuated in concert with known cyclic changes in the secretion of oestrogen, being maximal at pro-oestrus. Over the period of 50--81 ...
متن کاملProgesterone levels in plasma during the oestrous cycle of the sow measured by a rapid competitive protein binding technique.
An adaptation of the technique described by Johansson (1969), whereby progesterone was measured by a rapid competitive protein binding technique, has been used to determine the progesterone levels in the peripheral plasma of the cow (Edqvist, Ekman, Gustafsson & \l=A%o\str\l=o"\m,1970). The purpose of this paper is to report the usefulness of the same technique for the measurement of progestero...
