Biogenic monoamines in Hirudo medicinalis

Histochemie, 1968
The 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

Hirudo medicinalis Unplugged

Science, 1996
In August 1994, Ken Muller, chair of the neuroscience program at the University of Miami Medical School, asked if I would compose a musical tribute ([1][1]) to neuroscientist John G. Nicholls ([2][2], [3][3]) for his 65th birthday, as I am a scientist ([4][4]), a composer, and a former student ...

2022
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 Hirudo medicinalis species complex

Naturwissenschaften, 2012
Recently, 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".

Penile replantation using the leech Hirudo medicinalis

Urology, 1996
A 37-year-old chronic schizophrenic man underwent penile replantation after complete autoamputation using a kitchen knife. We report the first case of using medicinal leeches to salvage a penile replant after the development of postoperative venous congestion.

Nonassociative learning in the leech Hirudo medicinalis

Behavioural Brain Research, 2001
In 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.

Digit Replantation Applying the Leech Hirudo medicinalis

Clinical Orthopaedics and Related Research, 1989
Digits that were formerly assessed as nonreplantable may now be replanted with the help of the leech Hirudo medicinalis. The early experience with a series of patients who had relative contraindications for replantation is reported. In each case, venous repair was either marginal or technically impossible.

Multiple pseudolymphomas caused by Hirudo medicinalis therapy

Journal of the American Academy of Dermatology, 2000
Therapy with medicinal leeches (Hirudo medicinalis) is now frequently applied in plastic surgery and in the management of chronic venous insufficiency. We observed a patient in whom firm, brown-red, pea-sized papules developed at each site where leeches had been applied on the lower legs.

Hormonal control of spermatogenesis in Hirudo medicinalis

General and Comparative Endocrinology, 1967
Neurosecretion 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
