We discuss a rare presentation of malignant teratoma in a 63-year-old woman who was admitted to accident and emergency with abdominal distension, bloody diarrhoea and peritonitis. CT of the abdomen and pelvis showed free air in the abdomen and a gas-fluid filled cavity measuring 12×6 cm in the mid-pelvis with possible fistulation that was suspicious for malignancy. A 10×12 cm ruptured dermoid cyst was found intraoperatively, which was adherent to the bowel wall.

Objective: Our aim was to determine whether addition of zinc transporter 8 autoantibodies (ZnT8A) improved prediction of type 1 diabetes in a well-characterized cohort of islet cell antibody (ICA)-positive first-degree relatives.

Background: The factors that determine oocyte competency are poorly understood. It is believed that angiogenic factors are crucial. Modulation of these factors is therefore a central consideration.

For comparative purposes, growth hormone (GH), previously shown to stimulate IGF-1 secretion, was also included. Granulosa cells from ovarian follicles (3 to 5 mm) were cultured in multiwell plates for the first 48 hours, either in the presence or absence of 1% fetal bovine serum (FBS).

During the first and second estrus, two groups of gilts were inseminated with either 50 ml attenuated semen (n = 50) or physiological saline (n = 50). The control gilts (n = 49) remained untreated.

Restricted gilts were fed 2.0 kg d-1 of a diet formulated to provide 18% crude protein and 14.

The inhibition of PG synthesis with meclofenamic acid did not prevent either the decline in plasma progesterone or the release of relaxin.

Oral administration of meclofenamic acid (5.0 mg/kg body weight/day) on Days 112, 113 and 114 of pregnancy significantly delayed parturition compared to controls (P less than 0.

The effect of progesterone and prostaglandin administration on the timing of farrowing was studied in three groups of 25 sows each. Progesterone treatment (100 mg/day) on days 112, 113 and 114 of gestation (group I) significantly prolonged the gestation length to 116.4 +/- 0.

The concentration of lactose in the mammary secretion from individual glands of two sows increased significantly (P less than 0.01) between 0 and 24 h after parturition. In six sows studied during the perinatal period there was a negative correlation (r = -0.
