The histochemistry of the neurosecretory system in Hirudo medicinalis

General and Comparative Endocrinology, 1966
The 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, 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

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.

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.

Blutsauger in der Forschung: Hirudo medicinalis

Biologie in unserer Zeit, 2003
AbstractDas Epithel des Blutegels ist reich an Ionenkanälen und ‐pumpen und eignet sich in besonderer Weise für die Erforschung des molekularen Aufbaus und der Wirkungsweise des epithelialen Natriumkanals, ENaC. Dieser spielt beim Menschen eine große Rolle bei der Regulation des Blutdrucks, aber auch bei erblichen Formen des Bluthochdrucks.
