Comparison of Physicochemical and Structural Properties of Acid-Soluble and Pepsin-Soluble Collagens from Blacktip Reef Shark Skin

Fish collagen has been widely used in tissue engineering (TE) applications as an implant, which is generally transplanted into target tissue with stem cells for better regeneration ability. In this case, the success rate of this research depends on the fundamental components of fish collagen such as amino acid composition, structural and rheological properties. Therefore, researchers have been trying to find an innovative raw material from marine origins for tissue engineering applications. Based on this concept, collagens such as acid-soluble (ASC) and pepsin-soluble (PSC) were extracted from a new type of cartilaginous fish, the blacktip reef shark, for the first time, and were further investigated for physicochemical, protein pattern, microstructural and peptide mapping. The study results confirmed that the extracted collagens resemble the protein pattern of type-I collagen comprising the α₁, α₂, β and γ chains. The hydrophobic amino acids were dominant in both collagens with glycine and hydroxyproline as major amino acids. From the FTIR spectra, α helix (27.72 and 26.32%), β-sheet (22.24 and 23.35%), β-turn (21.34 and 22.08%), triple helix (14.11 and 14.13%) and random coil (14.59 and 14.12%) structures of ASC and PSC were confirmed, respectively. Collagens retained their triple helical and secondary structure well. Both collagens had maximum solubility at 3% NaCl and pH 4, and had absorbance maxima at 234 nm, respectively. The peptide mapping was almost similar for ASC and PSC at pH 2, generating peptides ranging from 15 to 200 kDa, with 23 kDa as a major peptide fragment. The microstructural analysis confirmed the homogenous fibrillar nature of collagens with more interconnected networks. Overall, the preset study concluded that collagen can be extracted more efficiently without disturbing the secondary structure by pepsin treatment. Therefore, the blacktip reef shark skin could serve as a potential source for collagen extraction for the pharmaceutical and biomedical applications.     

一起东佛里生奶绵羊附红细胞体病流行病学调查、诊疗报告

为探究附红细胞体在内蒙古呼和浩特市托克托县地区的流行情况,接诊呼和浩特托县地区某东佛里生奶绵羊养殖场病例,该场近一周多圈舍出现产奶羊只体温升高、精神沉郁、瘫软、食欲减退或废绝等症状,有出现症状1 ~ 2 d迅速死亡病例,也有使用抗生素硫酸庆大霉素-青霉素联用结合补液治疗1周无好转或死亡病例,死亡总数超8只,仍有10余只相似症状正在接受治疗。经现场剖检、圈舍环境调查、样品实验室检测,结合临床诊疗,确诊此次疫情为奶绵羊附红细胞体病,且周边羊养殖场（户）羊只也存在附红细胞体感染。说明附红细胞体在托克托县呈地方性流行。
