The Hirudo medicinalis species complex
Die Naturwissenschaften, 2012Recently, Hildebrandt and Lemke (Naturwissenschaften 98:995-1008, 2011) argued that the taxonomic status of the three European medicinal leeches, Hirudo medicinalis Linnaeus 1758, Hirudo verbana Carena 1820, and Hirudo orientalis Utevsky and Trontelj (Parasitol Res 98:61-66, 2005) is "questionable" since "all three species interbreed in the laboratory".

Biogenic monoamines in Hirudo medicinalis
Histochemie, 1968The distribution of certain catecholamines and indoleamines in the ventral nerve cord and the body segments of the medical leech, Hirudo medicinalis, was studied with the fluorescence microscope technique of Falck and Hillarp, with microspectrofluorometry, and with chemical determinations of the amines. The six cells of the segmental ganglia previously

Nonassociative learning in the leech Hirudo medicinalis
Behavioural Brain Research, 2001In the present study we examined nonassociative learning of the induction of swimming which was evoked by weak electrical stimulation in the leech Hirudo medicinalis. The behavioural response to stimuli applied repeatedly to the body wall at an inter-trial interval (ITI) of 1 min decreased, eventually ceased, and then recovered spontaneously.

Von den etwa 300 Egelarten, die es auf der Erde gibt, leben die meisten in Süßwasser. Je nach Größe, Anzahl und Bissstelle können sie für Fische und Amphibien, für badende Tiere oder Menschen unterschiedlich gefährlich sein. Umgekehrt hat sich der Mensch einige wenige Arten dieser Parasiten für medizinische Zwecke zunutze gemacht.

The histochemistry of the neurosecretory system in Hirudo medicinalis
General and Comparative Endocrinology, 1966The histochemistry of the neurosecretions of the brain of Hirudo is examined. The secretions of all of the cell types studied ( α 1 , α 2 β 1 β 2 ) are found to be proteinaceous, with possible small carbohydrate and lipid moieties. The PF-positive secretions of both α cell subtypes are characterized by a high content of cystine and a low ...

Hormonal control of spermatogenesis in Hirudo medicinalis
General and Comparative Endocrinology, 1967Neurosecretion in the brain of annelids has attracted considerable attention since its first recognition in the supraesophageal ganglion of Nereis by Berta Scharrer in 1936; in the polychetes and oligochetes it has been implicated in the control of reproduction, amongst other functions (see Bern and Hagadorn, 1965 for references). In the Hirudinea, the
