Heat identification by 17β-estradiol and progesterone quantification in individual raw milk samples by enzyme immunoassay Electron. J. Biotechnol.
Domènech,Anna; Pich,Sara; Arís,Anna; Plasencia,Carmen; Bach,Alex; Serrano,Alicia.
Background: There is a substantial decline in first-service-pregnancy-rate in dairy cows. In this regard, future prospects are to measure milk hormones on-farm and progesterone levels in milk are not enough to precise ovulation unless connected to other data. The objectives of this study were to investigate whether 17β-estradiol could be measured from individual cow milk samples using a commercially available non-radiolabelled enzyme immunoassay kit (EIA) with no previously reported milk application, and whether those detections could precisely illustrate 17β-estradiol pre-ovulation peak in spite of its limited concentration and short manifestation in milk. Results: Milk sample treatments for progesterone and 17β-estradiol EIA...

Toxic Effects of Methanolic Extract of Aspilia africana Leaf on the Estrous Cycle and Uterine Tissues of Wistar Rats International Journal of Morphology
Oluyemi,Kayode A; Okwuonu,Uche C; Baxter,D. Grillo; Oyesola,Tolulope, O.
Effects of graded dosages of methanolic extract of Aspilia Africana were examined on the estrous cycle, uterine weights and histology to determine its effects on the reproductive functions of 25 cyclic female rats. The rats were randomized into five groups A, B, C, D, and E. They were given Omg/kg body weight, 150 mg/kg body weight, 200 mg/kg body weight, 250 mg/kg body weight, and 300 mg/kg body weight, respectively. The effect on the estrous cycle was determined by vaginal lavage while routine histological preparations were done with haematoxylin-eosin stains. All values were statistically compared at appropriate confidence intervals. Estrous cycles were significantly reduced in a dose-dependent manner and histology revealed a dose-dependent toxicity
Tipo: Journal article Palavras-chave: Aspilia africana; Estrous; Uterine weight; Histology; Reproductive functions.
