You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["Disease", "Chemical"].

Please return the output as a JSON object of the format: {"Chemical" : ["Naloxone", ...], "Disease" : ["Hypotensive", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Angioedema associated with droperidol administration. Angioedema, also known as angioneurotic edema or Quincke's disease, is a well-demarcated, localized edema involving the subcutaneous tissues that may cause upper-airway obstruction. We report the case of a previously healthy 19-year-old man with no known drug allergies in whom angioedema with significant tongue swelling and protrusion developed within 10 minutes of the administration of a single IV dose of droperidol.
