Description: | CRICETULUS GRISEUS No 892 TESTIS WITH LEISH. DONOVANI 20-5-43 HEIDEN. (printed on a label gummed to the glass slde). BOUIN (written on the paper label). 892 Heidenh (scratched on the glass slide). MANU PONTERCORVO,Guido. May 20, 1943 Glasgow University, Glasgow, Scotland. This is a specimen of the testes of *Cricetulus griseus barabensis*, the Chinese striped hamster fixed with Heidenhain's hematoxylin. A stain and mordant of fresh 5% aqueous iron alum followed by the addition of hematoxylin (Natural Black 1, derived from the logwood tree Hematoxylon campechianum) and then differentiation in fresh 5% aqueous iron alum. The stain is then made of 1 gm hematoxylin in a solution of 10 ml. 90% ethanol in 80 ml.distilled water.
Rudolph Peter Heinrich Heidenhain (1834-1897) German physiologist.
The specimen appears to have also been treated with Bouin's fluid, a fixative or mordant made from a saturated aqueous solution of picric acid, formalin (40% aqueous solution of formaldehyde) and glacial acetic acid. Pol Bouin (1870-1962) French endocrinologist and histologist.physician and pathologist.
The process undergone was meiosis; the cell division in sexually reproducing organisms causing a reduction in the number of chromosomes, in the reproductive cells, from diploid (paired chromosomes) to haploid (single chromosomes) thus leading to the production of gametes (asexual) animals or plants.
The specimen was obtained from an animal killed by infection with *Leishmania donovani (infantum)* parasitic hemoflagellate bacterium of the subgenus *Leishmania leishmania* that infects man and animals and causes visceral *leishmaniasis*; the sandfly genera Phlebotomus and Lutzomyia are the normal vectors."
Appears to be connected with work done on Chinese sandflies as vectors for *Leishmania* published in 1931 by professor Edward Hindle (1886-1973) Chair of Zoology at Glasgow University. | License: | http://www.hmag.gla.ac.uk/spirit/rights/ | Publisher: | Hunterian Museum and Art Gallery, University of Glasgow | Rights holder: | Hunterian Museum and Art Gallery, University of Glasgow | Subjects: | SCIENTIFIC COLLECTION : | Source: | Hunterian Museum | Creator: | Hunterian Museum and Art Gallery, University of Glasgow | Identifier: | http://www.huntsearch.gla.ac.uk/cgi-bin/... | Language: | en-GB | Go to resource |
