HIT is caused by the formation of abnormal antibodies that activate platelets. If someone receiving heparin develops new or worsening thrombosis, or if the platelet count falls, HIT can be confirmed with specific blood tests.
For other uses, see Disneyland (disambiguation). Disneyland Park, originally Disneyland, is the first of two theme parks built at the Disneyland Resort in Anaheim, California, opened on July 17, 1955. It is the only theme park designed and built under the direct supervision of Walt Disney.
Walt Disney began the theme park revolution at Disneyland in a sleepy Anaheim orange grove and forever changed our notions of entertainment and vacations, let alone the amusement industry. That sleepy orange grove is now a destination resort with two parks, hotels, and more. While Disneyland remains the nexus of California's theme parks, there are a number of other noteworthy parks, including Universal Studios Hollywood, Legoland California, SeaWorld San Diego, and Six Flags Magic Mountain. Let's run those and other parks down, including smaller, more under-the-radar ones.
