Kıvırcık Koyunlarda Sinus Interdigitalis’in Morfolojik ve Immunohistokimyasal Özellikleri

Abstract

Interdigital sinus secretions play a role in sexual behavior and reproductive process of sheep. In the present study, it was aimed to characterize the topographical, anatomical and immunohistological features of interdigital sinus in Kivircik sheep. The interdigital sinuses were dissected from 50 forefeet of female Kivircik sheep which were slaughtered in the slaughterhouse. The shape of sinus resembled a pipe and was located between the proximal and distal interphalangeal joints of two digits. The wall of interdigital sinus had three layers as epidermis, dermis and fibrous capsule. Epidermis consisted of a stratified squamous keratinized epithelium. Sebaceous glands, hair follicles, arrector pili muscles, and apocrine sweat glands were in the dermis. Furthermore, there were vessels and adipose tissue in the fibrous capsule. There was immunohistochemical reaction for estrogen receptor expressed in epidermis, apocrin sweat glands and sebaceous glands of interdigital sinus. In conclusion, our results about the topographical, anatomical and immunohistological features of interdigital sinus are very important to understand sexual behavior and reproductive process of sheep, and to make a new approach for its surgery. Furthermore, this study is the first to report the interdigital sinus of Kivircik sheep immunohistochemically.

Bu çalışma ile Kıvırcık koyunlarda sinus interdigitalis'in, topografik, anatomik ve immünohistolojik özelliklerinin tanımlanması amaçlanmıştır. Çalışmada kullanılan sinus interdigitalis 'ler, mezbahada kesilen 50 adet Kıvırcık koyunun ön ayaklarından disseke edildi. Şekli bir pipoyu andıran sinus interdigitalis'in, iki parmak arasında articulatio interphalangea proksimalis ve distalis manus hizasında yerleştiği gözlendi. Sinus interdigitalis duvarının epidermis, dermis ve fibröz kapsül olarak üç katmandan oluştuğu gözlendi. Epidermis'in, çok katlı yassı keratinize epitelden oluştuğu saptanırken, dermis katmanında yağ bezleri, kıl folikülleri, mm. arrectores pilorum ve apokrin ter bezlerinin varlığı görüldü. Ayrıca, fibröz kapsül içerisinde kapillar damarlar ve yağ doku bulunmaktaydı. Sinus 'un epidermis, apokrin ter bezleri ve yağ bezlerinde östrojen reseptörleri için immünhistokimyasal tepki olduğu gözlendi. Sonuç olarak, sinus interdigitalis'in topografik, anatomik ve immünohistolojik özellikleri hakkında elde ettiğimiz sonuçlar, koyunlardaki seksüel davranış ve üreme sürecini anlama ve sinus interdigitalis'in operasyonlarına yeni bir yaklaşım geliştirmesi bakımından önemlidir. Çalışma, Kıvırcık koyunlarda sinus interdigitalis'in immunohistokimyasal yapısı üzerine yapılan ilk çalışmadır.

Erkek Hemşin Koyununda Glandula İnterdigitalis’in Morfolojik ve Morfometrik Yapısı ile Arterial Vaskularizasyonu

“…[25] and 16.74 mm by Süzer et al [28] . Length of the gland's corpus was determined as 6.95 mm in female Kıvırcık sheep by Süzer et al [28] and 9 mm in Akkaraman sheep by Çalışlar [18] .…”

“…Length of the gland's corpus was determined as 6.95 mm in female Kıvırcık sheep by Süzer et al [28] and 9 mm in Akkaraman sheep by Çalışlar [18] . In Hemshin sheep, total length of the gland was determined as averagely 27.92 mm, length of its corpus as 8.39 mm and length of its duct as 19.92 mm.…”

“…The histological, histochemical, immunohistochemical and electronmicroscopic features of the interdigital gland in native sheep breeds were described [4,16,22,26,28,29] . The wall structure of the Hemshin sheep' interdigital gland was composed of epidermis, dermis, and a capsule and hair follicles, sebaceous glands, sweat glands, muscle fibers, and apocrine glands were observed in the interdigital glands of the Hemshin sheep like Kıvırcık [16] and Akkaraman [22] sheep.…”

“…Contrary to Janicki et al (2003), who reported that the interdigital gland of roe deer (Capreolus capreolus L.) was devoid of connective tissue capsule and sweat glands, the connective tissue capsules layer in our study consisted of a few fibrocytes and fibroblast layers, dense collagen fibres, adipose tissue and blood vessels. In a study conducted on Kivircik sheep (Süzer et al, 2016), it was reported that the epithelium of apocrine sweat glands was simple columnar in the body and simple cuboidal in the neck. In our study, the epithelium of apocrine glands was observed as a single layer of cuboidal epithelium.…”

“…Apocrine sweat glands are considered to be pheromone‐producing odour glands (Beir et al., 2005 ; Bigiani et al., 2005 ) and their secretions have an important role in the delimitation of territorial space (Atoji et al., 1995 ; Evans, 1988 ). The interdigital sinus contains a large amount of apocrine glands in its structure (Süzer et al., 2016 ).…”
