Some biochemical changes in mouse after in-vivo irradiation of pancreas with ultrasound

875 KHz continuous wave of ultrasound at 2.5 W/Cm2 intensity revealed certain biochemical and enzymological changes in mouse pancreas and liver following the irradiation of pancreas in-vivo for a total of 300 seconds spread over five days. The sacrifice of the animals was carried out on day 0, day 1, day 5 and day 10. Blood glucose was reduced significantly with concomitant increase in liver glycogen. Glucose-6-phosphatase in liver was decreased significantly while glycogen phosphorylase showed marginal variations. Increased calcium pool in pancreas along with Ca2+ activated ATPase was observed. These alterations were prevalent in all the days of sacrifice and also for more than 10 days after the last exposure. The results are suggestive of ultrasound could stimulate the release of pancreatic secretions.
