In order to evaluate the hypothetical activity of foetal hepatic factors on putative yolk-sac haemopoietic stem cells we used the Double Diffusion Chamber (DDC) techniqUe. The DDC were made of a regulator compartment, where foetal hepatic tissue was introduced and a test compartment where visceral yolk-sac cells were cultured. In this system a hepatic signal induced the yolk-sac stem cells to d...

MRI assessment of the foetus has been around for 25 years although in routine practice only for the last few years. The tackling of the main challenge of foetal movement was paramount and with this aside the use of the technique has grown exponentially. Arguments related to safety and availability are often used against its routine implementation. However, for a number of specific indications, ...

Amnioscopy is available as an out-patient procedure, whenever hazards threaten the life of the foetus during late pregnancy. An endoscope-the amnioscope-is passed into the cervical canal so that the amniotic fluid can be inspected through the intact forewaters. Amniotic fluid which is clear, or milky from emulsification of vernix, indicates that conditions within the uterus are normal. Green or...

exposure to high dosages of sulfur mustard (sm) can cause bone marrow depression, immune system suppression, impairment of the immune functions, and eventually results in diseases due to secondary immune disorders. in this article, we have studied the effects of this poison on iranian veterans by analysis of related published studies. in a systematic search, the effects of sm gas on iranian vic...

objective: hypericum perforatum (st. john's wort) has long been used in traditional medicine to treat a variety of internal and external ailments. the present study was done to evaluate the immumodulatory potentials of the hydroalcoholic extract of h. perforatum. materials and methods: twenty male balb/c-mice were randomly allocated in two equal groups and immunized with sheep red blood ce...

1. Homozygous α-thalassaemia-1 can be predicted reliably using ultrasound measurement of the foetal cardiothoracic ratio at 12 to 13 weeks’ gestation, but not at 10 to 11 weeks’ gestation. 2. When an optimal foetal cardiothoracic ratio cannot be obtained with an abdominal ultrasound examination at 12 to 13 weeks’ gestation, a vaginal ultrasound examination is useful. 3. The use of ultrasonograp...

We investigated the effects of different windows of testosterone propionate (TP) treatment during foetal and neonatal life in female rats to determine whether and when excess androgen exposure would cause disruption of adult reproductive function. Animals were killed prepubertally at d25 and as adults at d90. Plasma samples were taken for hormone analysis and ovaries serial sectioned for morpho...
