Abstract/Summary

Diagnostic ultrasounds are widely used in this age of technology it is commonly used to diagnose various pain, swelling, and infection. It can also assess damage of the following internal organs, but not limited to the blood vessels, liver, gallbladder, spleen, pancreas, kidneys, bladder, uterus, ovaries, eyes, thyroid and parathyroid glands, and scrotum. It can also guide some minor procedures such as needle biopsies.

The general objective of this study is to find out the morphological effects of varying diagnostic ultrasound exposure on the physical development of Syrian hamster embryos.

This study used twenty one pairs of Syrian hamsters which were divided into three groups' control group which consisted of ten pairs of Syrian hamster whose females were not exposed to any diagnostic ultrasound, a first experimental group which consisted five pairs of Syrian hamster whose females were exposed to the diagnostic ultrasound once, and a second experimental group which consisted of six pairs of Syrian hamsters whose females were exposed to the diagnostic ultrasound twice. The results were analyzed using Multivariate Analysis of Variance (MANOVA) procedure.

The results showed that there were significant differences in the means of the pups' masses, body lengths and leg lengths. On the other hand, there was no significant difference in the means of the arm lengths of the pups there were also no external sensory organs that were missing. However, there were additional observations that were noted such the mortality rate and responsiveness of the pups. It was observed that the pups from the second experimental set up were less responsive and had less chances of survival as compared to the pups in the control group."
