【英语时差8,16】什么是卟咻症？2

（单词翻译）

 In this form of hereditary¹ porphyria, the skin becomes white with anemia² and very sensitive to light. (Remember that vampires⁴ only come out at night.) The teeth of Porphyria victims become reddish and even glow under ultraviolet light. Hair grows faster and thicker than usual; and sores on the skin can develop that eventually erode⁵ away the nose or fingers. Could this pale, hairy, deformed⁶ creature of the night be a vampire³?And what about the garlic? People with porphyria do well to stay away from garlic, which contains a chemical known to aggravate⁷ the symptoms of this disease. Of course porphyria victims don’t suck blood from people’s necks, and even if they did, the bite wouldn’t transmit the disease. However, the inability of some people to break down their own hemoglobin may have given Bram Stoker a model for his legend of Dracula.
