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:

Reversal of neuroleptic-induced catalepsy by novel aryl-piperazine anxiolytic drugs. The novel anxiolytic drug, buspirone, reverses catalepsy induced by haloperidol. A series of aryl-piperazine analogues of buspirone and other 5-hydroxytryptaminergic agonists were tested for their ability to reverse haloperidol induced catalepsy. Those drugs with strong affinity for 5-hydroxytryptamine1a receptors were able to reverse catalepsy. Drugs with affinity for other 5-HT receptors or weak affinity were ineffective. However, inhibition of postsynaptic 5-HT receptors neither inhibited nor potentiated reversal of catalepsy and leaves open the question as to the site or mechanism for this effect.
