Aspirin And Ibuprofen Have An Impact On The Heart Rate Of The Lumbriculus Variebiotics?
This is evident in Figure 1 which shows a comparison between our caffeine trials and the spring water control trials. We found that placing these worms into a caffeine solution does cause an increase in their heart rate, and previous studies had similar findings. In a study conducted by Lesiuk et al. (1999), which involved looking at the effects of placing Lumbriculus variegatus into solutions of increasing caffeine concentrations, it was found that the pulsation rates of these worms were on an upward rising trend as the caffeine concentrations increased. While our study did not look at increasing concentrations of caffeine, it did also show the same findings that caffeine has the effect of increasing the heart rate of Lumbriculus
