I-BSE iletha umthelela ojulile embonini Yedivayisi Yezokwelapha. Hhayi iKhomishini YaseYurophu kuphela, kodwa futhi i-Australia ngisho nakwamanye amazwe ase-Asia aphakamisa ibha yomshini wezokwelapha oqukethe noma owenziwe umthombo wezilwane, ocishe wavala umnyango. Imboni kufanele icabange ngokushintsha izinsiza zokwelapha ezitholakala manje ezilwaneni ngezinto ezintsha zokwenziwa. I-Plain Catgut enesidingo esikhulu semakethe sokushintshwa ngemuva kokuvinjelwa e-Europe, ngaphansi kwalesi simo, i-Poly(glycolide-co-caprolactone)(PGA-PCL)(75% -25%) , ukubhala okufushane njenge-PGCL, yathuthukiswa njengoba kuye kwenzeka. ukusebenza okuphezulu kokuphepha kwe-hydrolysis okungcono kakhulu kune-Catgut by Enzymolysis.
