Sericin-derived oligopeptides obtained from silk cocoons were investigated for the in vivo hypotensive effect and investigated for the underlying mechanism involved in vasodilation in isolated rat thoracic aorta. In normotensive anesthetized rats, oligopeptides induced an immediate and transient hypotensive activity. In rat aortic rings, oligopeptides induced a concentration-dependent vasorelax...
Silk sericin (SS)/silk fibroin (SF) blend nanofibers have been produced by electrospinning in a binary SS/SF trifluoroacetic acid (TFA) solution system, which was prepared by mixing 20 wt.% SS TFA solution and 10 wt.% SF TFA solution to give different compositions. The diameters of the SS/SF nanofibers ranged from 33 to 837 nm, and they showed a round cross section. The surface of the SS/SF nan...
Studies reveal that during processing of cocoons, natural polymers in the cocoon become sufficiently swollen under water, and depending on external ambience, climatic temperature, humidity, sericin contained does not evaporate, suffocate well water. As a result, moisture content decreases there are many breaks yarn due to poor spinning, which increases fiber waste. In order prevent these proces...
