Ultrasound-induced enhancement of ACh, AChE and GABA in fetal brain tissue of mouse.
Pregnant mice were exposed to continuous-wave (CW) ultrasound of 875 kHz frequency at 1 W/cm2 for 300 and 400 s, spread over five days, starting from the sixth day of pregnancy. The neurotransmitters, acetylcholine (ACh) and gamma amino butyric acid (GABA), and the associated enzyme acetylcholinesterase (AChE) levels, were estimated in the exposed fetal brains. Enhanced levels, significant at p < 0.001, were observed in the brains excised on day 10, day 15 and day 20 of gestation compared to sham-exposed and cage-control brains.
