Botulinum toxin A is a kind of neurotoxin produced by clostridium botulinum, and has been applied for nearly thirty years in China.The target of BTX-A is to selectively cleave the synaptosome-associated protein of 25 KD molecular mass, commonly abbreviated SNAP-25, thereby inhibiting neurotransmitter release and causing chemodenervation. The potential application of botulinum toxin A in treating the spasmodic dysphonia, hemifacial spasm, tinnitus, rhinitis has been confirmed both in clinical practice and previous studies. This paper is to

Bone density was compared across four bones (eleventh vertebra, lower jaw, pelvic girdle, and first dorsal-fin pterygiophore). On average, the lower jaw was significantly denser than the other bones. We found no correlation between bone density and depth or between bone density and phylogenetic relationships. Instead, we observed that bone density increases with increasing specimen length within and between species. This study adds to the growing body of work that suggests bone density can increase with growth in fis
