Many books have been written that cover various aspects of these devices, including the fluid transport, system properties, and bioanalytical applications.

Net fluid transport was measured in two ways.

Net fluid transport was expressed as l.min -1.100 cm -2 serosa.

A constant net fluid transport was recorded for 30-60 minutes.

Net fluid transport was measured in 26 rats on days 6-9 after they had been infected with the parasites.

Compared with the control animals, both groups of infected rats exhibited a significantly different fluid transport.

These findings agree with results reported by other researchers investigating fluid transport in vivo.

Nolla et al made a more thorough analysis, determining fluid transport on days 4, 6, 9, and 13.

On day 30, when the nematodes had been expelled from the gut, fluid transport was back to control values.

The rate of fluid transport observed on days 11-14 was approximately twice as high as that seen in control animals.
