    Notes: Summary Minis have a doubling time of 2.4 days,maxis of 8 days.Minis regenerate head and foot 5 h faster thanmaxis.Minis have fewer tentacles (4.6) per head thanmaxis (6.1). Inmini the concentration of the head activator is equal to that inHydraattenuata, but the concentration of the head inhibitor is reduced (2-fold in the head, 1.2-fold in the body). The concentrations of the foot factors are normal.Minis respond likeHydra attenuata to head activator, foot activator and foot inhibitor, but they are less sensitive to head inhibitor Inmaxi the concentration of the head activator is higher than inmini (5-fold in the head, 10-fold in the body) and that of the head inhibitor is also higher (4-fold in the head, 5-fold in the body). The concentration of the foot inhibitor is normal, that of the foot activator is doubled.Maxis are insensitive to added head activator and less sensitive to added head inhibitor and foot inhibitor. Their response to foot activator is normal.

    Description / Table of Contents: Zusammenfassung Berichtet wird über ein Versuchsmodell, das es zuverlässig ermöglicht, am Beispiel des Rattenpfotentestes ein posttraumatisches Ödem mit hoher Volumenausbeute und sicherer Reproduzierbarkeit unter größtmöglicher Gewebeschonung zu erzeugen. Das Ödem wird durch Quetschen der Rattenhinterpfote unter standardisierten Bedingungen in einer Wringe mit gegenläufigen Holzwalzen induziert und volumetrisch gemessen. Die Ergebnisse werden diskutiert und denen anderer Versuchsmodelle gegenübergestellt.
    Notes: Summary A standardized reproducible technique is reported for inducing traumatic edema in the rat paw showing considerable swelling volume and low tissue damage. The edema is measured volumetrically subsequent to squashing the rat paw under standardized conditions in a wringing-machine with two wooden rollers. The technique is compared with other methods.
