Background and Importance: Abscess of the hypophysis or pituitary adenoma is a very rare entity, and its preoperative diagnosis could be challenging. The clinical presentation is less specific, and despite the recent advancement in imaging, diagnosis before surgery is still difficult. Case Presentation: We reported two cases of pituitary abscesses in patients aged 38 and 42 years. The first ...

The treatment during the embryonic preimplantation phase of Wistar rats with the Pradosia huberi extract did not interfere with the water and feed consumption, as well as upon the body-weight gain. However, it has expressed a decrease of the uterine implant number, followed by the preimplantation losses at all applied doses (1.22, 6.1, and 30.5 mg/kg), and the number of embryonic resorptions in...

The root meristem consists of populations of distal and proximal stem cells and an organizing center known as the quiescent center. During embryogenesis, initiation of the root meristem occurs when an asymmetric cell division of the hypophysis forms the distal stem cells and quiescent center. We have identified NO TRANSMITTING TRACT (NTT) and two closely related paralogs as being required for t...

Duplication of the pituitary (hypophysis) and other structures in the region of the mouth may be regarded as a minor degree of partial twinning which did not go on to frank monster formation. Ahlfeld (1880), who considered that the first grade of duplication of the anterior end of the body was a doubling of the hypophysis, reports one case in man; and McCall (1943) records a double Rathke's pou...

Changes in chicken embryo thymus after partial decerebration (including the hypophysis) and hypophyseal allograft were investigated. Chicken embryos were partially decerebrated at 36-40 hr of incubation and on day 12 received a hypophyseal allograft from 18-day-old donor embryos. The embryonic thymuses were collected on day 18 and examined with histological methods, tested for the anti-thymosti...
