Measurement of oxytocin concentrations in plasma and ovarian extracts during the oestrous cycle of mares.
Jugular venous blood samples were collected throughout a complete oestrous cycle from 9 mares for measurement of progesterone and oxytocin by radioimmunoassay. Mean oxytocin concentrations remained at approximately 1 pg/ml throughout, with no evidence of cyclic variation in the release pattern. Extracts of corpus luteum and follicles obtained from a further 33 mares at different stages of the c...
متن کاملPlasma concentrations of LH, progesterone and oestradiol during the oestrous cycle in swamp buffaloes (Bubalus bubalis).
Plasma concentrations of LH, progesterone and oestradiol were measured in 5 cyclic swamp buffaloes. Progesterone levels began to increase after Day 5 (Day 0 = the day of oestrus) and reached a plateau after Day 10. A rapid decrease in progesterone levels occurred during the 5 days before oestrus, followed by a sustained increase in oestradiol concentrations. Basal LH levels decreased towards th...
متن کاملOestradiol levels in sheep plasma during the oestrous cycle.
The concentration of oestradiol was measured by radioimmunoassay in ovarian venous plasma collected from ewes of three breeds (Finnish Landrace, Scottish Blackface and Tasmanian Merino) on Day 9 of the oestrous cycle and in jugular venous plasma collected daily around oestrus in two of these breeds. The mean +/- s.e.m. concentration in the ovarian venous plasma of the Merino (44.1 +/- 7.6 pg/ml...
متن کاملHistomorphometrical study of the cervix during the oestrous cycle in adult Azarbaijan buffalo
In this study, genital tracts of 20 healthy non-pregnant buffaloes were collected from Urmia abattoir.These genital tracts were selected based on their ovaries conditions, half of them were in follicular phase and the other half were in luteal phase. The samples were taken from anterior, middle and posterior regions of the cervix and fixed in 10% buffer formalin. Then, histological sections of ...

intestine is normal with no evidence of malabsorption." Three-day faecal fat excretion and xylose absorption test were normal. Although the serum B12 level was not available at the time, the evidence from blood, marrow, and barium meal examinations suggested vitamin B12 deficiency due to pernicious anaemia, and treatment was started with hydroxocobalamin 1 mg intramuscularly daily for four days...
