PLANARIA HYSTERIA: DOES RED LED LIGHT AID IN THE REGENERATION OF
PLANARIA AND PROMOTE WOUND HEALING?, Carley E.Andrews, Deshler High
School, Tuscumbia, AL 35674.
This experiment was conducted in order to determine if exposure to
red LED light aided in the regeneration of planaria. Thirty whole
planaria were cut in halves, and the 60 cut planaria were separated into
six different groups that received varying amounts of exposure to the
red LED light. Groups 1 and 2 were the control and received no exposure
to the red LED light. Groups 3 and 4 were exposed to the red LED light
for 60 seconds once per day. Groups 5 and 6 were exposed to the red LED
light for 60 seconds twice per day. After a seven day period, the
average daily growths and the average total growths of each group were
compared. The groups receiving no LED exposure grew a total average of
0.85 mm and a daily average of 0.12 mm. The groups receiving LED
exposure once per day grew a total average of 1.60 mm and a daily
average of 0.23 mm. while the group exposed twice per day to the red LED
light grew a total average of 3.01 mm and a daily average of 0.43 mm.
These results show that exposing planaria to red LED light significantly
aids in their regeneration, and these results could possibly be applied
to the healing of human wounds.
