Effects of neurotrophins on gastrointestinal myoelectric activities of rats

Figure 1 Electrical activity recorded directly from four electrode sites on the gastric antrum (a) at 5 mm proximal to the pylorus, on the duodenum (b) and jejunum (c) respectively at 5 cm and 20 cm distal to the pylorus, and on the transverse colon (d) at 5 cm distal to the ileocaecal junction in one fasting rat.

Figure 2 The effects of rh-NT-3 on the myoelectric activities respectively recorded from gastric antrum (a), duodenum (b), jejunum (c), transverse colon (d), and distal colon (e) in one case. The arrows indicated the time point of rh-NT-3 injection via tail vein at a dose of 20 μg·kg^-1.
