Objective: Hexane-acetyl acetate (HAAF) and acetyl acetate-methanol fractions (AAMF) but not aqueous methanol (AQMF) and aqueous fractions (AQF) of Adansonia digitata Linn root bark induce reproductive effects in female Wistar rats. The current study investigated the exclusive components of HAAF, AAMF, AQMF, and AQF of Adansonia digitata Linn root bark and the effect of AAMF on the female Wistar rat's oestrous cycle progression, and hormone and lipid profiles.
Methodology: Gas chromatography and mass spectrometry explored the components of HAAF, AAMF, AQMF, and AQF.
Article Synopsis
- The study aimed to assess the effectiveness of digital rectal palpation (DRP) for early pregnancy diagnosis in Red Sokoto goats and compared results from two experiments.
- Experiment I involved 68 goats, where does were divided into groups for different estrus synchronization methods (PGF α, progesterone pessaries, and Control), and pregnancy was diagnosed through various techniques including ultrasonography (US) and DRP.
- Experiment II replicated this with 51 goats, using different artificial insemination methods but the same pregnancy diagnosis techniques, ultimately showing consistent results across both experiments.
- The DRP technique was found to be effective and comparable to other diagnostic methods like US, progesterone assays, and non-return-to-heat checks for early pregnancy
Background And Aim: Different species of trypanosomes have been reported to cause varying degrees of reproductive disorders in pregnant and non-pregnant animals under experimental infections. Information on reproductive disorders and losses in animals naturally infected with trypanosome species are few. This study was carried out to assess the abnormalities in the genital organs (ovaries, oviduct, uterus, cervix, and vagina) of female cattle naturally infected with trypanosomes in and around Abuja, Nigeria.

Eighty-four rats, randomly assigned to 7 groups of 12 rats each, were used for the study. Varying low doses (0.

Our data showed a significant surge in the level of sialic acid with parasitaemia. The pattern followed a polynomial function we had reported for erythrocyte sialic acid in mice undergoing acute infection by T.
