Vasopressin (arginine vasopressin, AVP; antidiuretic hormone, ADH) is a peptide hormone formed in the hypothalamus, then transported via axons to, and released from, the posterior pituitary into the blood. AVP has two principle sites of action: the kidney and blood vessels.
Cutaneous anthrax symptoms can include: 1  A group of small blisters or bumps that may itch. 2  Swelling can occur around the sore. 3  A painless skin sore (ulcer) with a black center that appears after the small blisters or bumps Most often the sore will be on the face, neck, arms, or hands.
In cutaneous anthrax, itching of an exposed skin surface occurs first, followed by a lesion that becomes papular, then vesicular and in 2-6 days develops into a depressed black esehar (see picture). The esehar is usually surrounded by moderate to severe and very extensive edema, sometimes with small secondary vesicles.
