| Summary: | <b>Aim:</b> In this study, histology of the skin and number and area
of the argyrophilic nucleolar organiser regions (AgNORs) of
the germinal matrix epithelial cells of the chinchilla were
investigated by light microscopic techniques.<p>
<b>Materials and Methods:</b> Skin samples were taken from
15 adult healthy chinchilla, fixed in formol saline and immersed
in parafine. Tissue sections were stained with
Crossman's trichrome, Gordon and Sweet's reticuler fiber,
Verhoef's elastic fibre and AgNOR staining methods. The total
thickness of epidermis and dermis, hair follicle numbers
per square milimetres, and number and area of AgNORs of
the germinal matrix epithelial cells were measured.<p>
<b>Results:</b> AgNORs were seen as 1-4 black dots which distributed
in the nuclei of the germinal matrix cells of the hair
follicles. The chinchilla compound hair follicle consisted of
one or two primary follicles surrounded by multiple smaller
secondary follicles. The ratio of secondary to primary hair
follicles (S/P) was 13/1.<p>
<b>Conclusion:</b> In further studies on a larger population seasonal
differences, determination of number and distribution
of hair follicules and AgNOR parameters in the germinal
matrix cell should be used as significant criteria for fur
quality in selection. |
