Alcyonidium Diaphanum
''Alcyonidium diaphanum'', commonly called the sea-chervil (after the herb which it resembles), is a species of bryozoan found in the North Atlantic The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and .... It can cause a rash known as " Dogger Bank itch" when handled for prolonged periods.

Anthriscus
''Anthriscus'' (chervils) is a common plant genus of the family Apiaceae, growing in Europe and temperate parts of Asia. It comprises 15 species. The genus grows in meadows and verges on slightly wet porous soils. One species, '' Anthriscus cerefolium'' is cultivated and used in the kitchen to flavor foods. ''Anthriscus'' species are used as food plants by the larvae of some Lepidoptera species including the mouse moth (recorded on cow parsley). The hollow stem is erect and branched, ending in compound umbels of small white or greenish flowers. The leaves are bipinnate or tripinnate.

Bryozoa
Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding. Most marine bryozoans live in tropical waters, but a few are found in oceanic trenches and polar waters. The bryozoans are classified as the marine bryozoans (Stenolaemata), freshwater bryozoans (Phylactolaemata), and mostly-marine bryozoans (Gymnolaemata), a few members of which prefer brackish water. 5,869living species are known. At least two genera are solitary (''Aethozooides'' and ''Monobryozoon''); the rest are colonial. The terms Polyzoa and Bryozoa were introduced in 1830 and 1831, respectively. Soon after it was named, another group of animals was discovered whose filtering mechanism looked similar, so it was included in Bryozoa until 1869, when the two groups were no ...

North Atlantic
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Dogger Bank Itch
Dogger Bank itch is a cutaneous condition characterized by a long-lasting dermatitis caused by exposure to the sea chervil, ''Alcyonidium diaphanum'', a bryozoan. The disease, common in fishermen who work in the North Sea, has been recognized by the Danish Workman's Compensation Act since 1939. Signs and symptoms Pathogenesis The rash is caused by a type of cell-mediated hypersensitivity reaction; this type of hypersensitivity normally occurs in people who become sensitized to volatile organic compounds. Although in some instances several years may be required to develop sensitivity, this time period may vary greatly depending on the individual. In Dogger Bank itch, sensitivity is acquired after repeated handling of the sea chervils that become entangled in fishing nets. The specific toxin responsible for the rash was determined to be the sulfur-bearing salt (2-hydroxyethyl) dimethylsulfoxonium chloride. This salt is also found in some sea sponges and has potent in vitro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
