Rapid method for fetal brain fixation.
نویسنده
چکیده
A quicker alternative to the standard removal and fixation of brain tissue was sought. Whole fetal brains were fixed in situ using a mercuric based fixative. The subarachnoid space was perfused overnight with Heidenhain's Susa fixative. The following day the brains were removed from the cranium in the standard manner. After storage for three days in Susa's fixative the brain was sliced and processed, with excellent preservation of gross and microscopic architecture. The cost is only marginally higher than that of commercial formalin.

Rapid processing of fetal skin for prenatal diagnosis
A method has been developed for rapid processing of fetal skin for prenatal diagnosis of hereditary skin diseases by light and electron microscopy. Fixation, dehydration, embedding, and polymerisation can be achieved in about 5 h. The quality of tissue preservation compares favourably with that produced by slower conventional techniques. This procedure may provoke a wider interest in the potent...

Objective: one of the best tests for the assessment of a fetus is the biophysical profile test which has a significant effect on fetus health and the outcome of pregnancy. The present study was designed to determine the relationship between the full biophysical profile and the rapid biophysical profile tests in antepartum fetal surveillance. Patients and Methods: In this prospective study, Sin...

متن کاملRapid complement fixation technique for estimating complement-fixing antigen elution profiles of viruses from gel filtration columns.
The complement fixation elution profiles of dengue-2 virus-infected suckling mouse brain supernatant fluids from Sephadex G-200 columns were compared by the antigen end-point titration procedure and by a complement dilution technique. The latter technique was found to be a quick method for approximating the complement-fixing antigen in eluates.
متن کاملThe impact of COVID-19 during pregnancy on fetal brain development
The development of the brain as the most complex structure of the human body is a long process that begins in the third week of pregnancy and continues until adulthood and even until the end of life (1). Human brain myelination begins one to two months before birth in the visual system and eventually lasts until the age of two in other sensory systems and then the motor systems (4). Processes a...
