This paper presents a 73 years old male with three weeks history of intermittent hemoptysis, dysphagia, dyspnea, stridor, and suffocations sensation. By means of fibrotic bronchoscopic examination, the cause was found to be a leech in the glottis. It was removed by injection of 4 ml lidocaine 2%. Infestation into the respiratory tract by a leech may become lethal because of hypoxia and death se...

Using immunocytochemistry techniques, we demonstrated specific immunostaining with antibodies rose against fragment (547-560) and (614-626) of bovine chromogranin B (CGB) at the level of brain and the tegument of the leech Theromyzon tessulatum. The used of these antibodies on leech sections revealed immunopositive labeling in neurons and glial cells of the central nervous system (CNS), and epi...

BACKGROUND The use of leeches can effectively increase the salvage rate of flap congestion. However, the first reaction from patients and carers in using leeches in clinical fields is strong aversion. This can be due to the fact that development of our culture from agriculture to industrial society, coming across leeches became fairly rare. Also because of the biological traits that leeches car...

Widespread mouth ulcerations were observed in largemouth bass collected from eight inland lakes in the Lower Peninsula of Michigan during the summer months of 2002 and 2003. These ulcerations were associated with, and most likely caused by, leech parasitism. Through the use of morphological dichotomous keys, it was determined that all leeches collected are of one species: Myzobdella lugubris. A...

The Ionized calcium-Binding Adapter molecule 1 (Iba1), also known as Allograft Inflammatory Factor 1 (AIF-1), is a 17 kDa cytokine-inducible protein, produced by activated macrophages during chronic transplant rejection and inflammatory reactions in Vertebrates. In mammalian central nervous system (CNS), Iba1 is a sensitive marker associated with activated macrophages/microglia and is upregulat...

Once considered as lacking intrinsic immune mechanisms, the CNS of vertebrates is now known to be capable of mounting its own innate immune response. Interestingly, while invertebrates have been very useful in the interpretation of general vertebrate innate immunity mechanisms, only scarce data are available on the immune response of nervous tissue within this group. This study provides new dat...

A 55-year-old Chinese woman presented with a 3-week history of unilateral left-sided epistaxis and nasal obstruction. She had swam in a freshwater stream 1 month prior to the onset of symptoms. Endoscopic examination revealed a live leech at the left middle meatus with a large part of its body inside the left maxillary antrum. Local anaesthetic was applied to anaesthetise the leech and facilita...

Leeches are segmented worms belonging to Phylum Annelida and make up the subclass Hirudinea. Leeches have been historically used in medicine to suck blood from patients. Ocular infestation with leech is rare, moreover it is often misdiagnosed. In this report, we describe 2 patients with continuous bright ocular bleeding after swimming in a pool, and pseudo iris prolapse in a child after trauma ...

In this study 47 leech species from Poland are listed. They belong to two orders, two suborders, five families and 17 genera. The checklist also includes the information about hosts, distribution in Poland and references concerning the leech species discussed in this study.

Based on physiological investigations, Nicholls and Baylor (1968) identified and described three types of mechanosensory neurons in segmental ganglia of medicinal leech: T-cells receiving touch information, P-cells sensitive to changes in pressure applied on the skin, and N-cells affected by nociceptive stimuli. The electrical excitability and the passive electrical parameters of the somatic me...
