由于其毛笔毛囊的独特特性,Sunda豪猪皮肤的复杂性已成为一个重要的话题。皮肤的结构和化学成分影响了许多生理和其他条件。一般来说,羽毛笔大一些,比头发更强壮,更坚硬;因此,皮肤结构需要适应以支持其生理机能。皮肤的强度取决于其胶原蛋白的组成和排列;因此,这项研究旨在使用picrossiriusred染色,根据偏振光下Sunda豪猪皮肤的特定特征,分析粗细纤维的组成和分布。所使用的皮肤样本来自8个Sunda豪猪成年人的胸背和腰s部。组织学染色使用picrosiriusred方法进行,在偏光显微镜下观察样品,并用软件进行分析。结果表明,皮肤由36%-65%的粗纤维组成,20%-35%的细纤维和少量的其他类型,腰骶部区域的粗细纤维组成高于胸背区域。此外,胸背和腰骶区域在更深的真皮和毛囊中具有最高的厚纤维组成,分别。这些表明,由于桑达豪猪的毛笔衍生物,其皮肤结构的复杂性与其胶原蛋白的组成和分布有关。
The complexity of the Sunda porcupine skin has become an important topic due to the unique characteristics of its quill follicles. The structure and chemical composition of the skin has affected many physiological and other conditions. Generally, quills are larger, stronger and stiffer than hair; therefore, the skin structure needs to adapt to support their physiology. The strength of the skin is determined by its collagen composition and arrangement; therefore, this study aims to analyse the composition and distribution of thick and thin fibres based on the specific characteristics of Sunda porcupine skin under polarized light using picrosirius red staining. The skin samples used were from the thoracodorsal and lumbosacral regions of eight Sunda porcupine adults. The histological staining was carried out using the picrosirius red method, while the samples were observed under a polarized light microscope and analysed with software. The results showed that the skin is composed of 36%-65% thick fibres, 20%-35% thin fibres and small amounts of other types with the lumbosacral region having higher compositions of thick and thin fibres than those in the thoracodorsal region. Furthermore, the thoracodorsal and lumbosacral regions have the highest composition of thick fibre in the deeper dermis and quill follicle, respectively. These demonstrated that the complexity of the skin structure of Sunda porcupine due to its quill derivates correlated with its collagen composition and distribution.
