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:

Behavioral effects of MK-801 on reserpine-treated mice. The effects of dizocilpine (MK-801), a noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist, were studied on dopamine-related behaviors induced by reserpine treatments. This study focuses on behavioral syndromes that may used as models for Parkinson's disease, or tardive dyskinesia, and its response after glutamatergic blockage. Reserpine (1 mg/kg), administered once every other day for 4 days, produced increases in orofacial dyskinesia, tongue protrusion and vacuous chewing in mice, which are signs indicative of tardive dyskinesia. Reserpine also produced tremor and catalepsy, which are signs suggestive of Parkinson's disease. MK-801 (0.1 mg/kg), administered 30 min before the observation test, prevented the vacuous chewing movements, tongue protrusions and catalepsy induced by reserpine. However, MK-801 injection produced a significant increase of tremor in reserpine-treated mice. Reserpine (1 mg/kg), administered 90 min before the test and followed by apomophine injection (0.1 mg/kg) 5 min before the test, did not produce oral dyskinesia in mice. On the other hand, reserpine induced increases in tremor and catalepsy compared to control mice. MK-801 (0.1 mg/kg) administration attenuated the catalepsy and tremor induced by reserpine. Pretreatment with reserpine (1 mg/kg) 24 h before the observation test produced increases in vacuous chewing movements and tongue protrusion, as well as increases in tremor and catalepsy, whereas MK-801 (0.1 mg/kg) injection 90 min before the test reversed the effects of reserpine. These results show that reserpine produces different and abnormal movements, which are related to dose and schedule employed and can be considered as parkinsonian-like and tardive dsykinesia signs. The glutamatergic blockage produced by NMDA can restore these signs, such as vacuous chewing movements, tongue protrusions, catalepsy and tremor according to the employed model.
