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:

Water intoxication associated with oxytocin administration during saline-induced abortion. Four cases of water intoxication in connection with oxytocin administration during saline-induced abortions are described. The mechanism of water intoxication is discussed in regard to these cases. Oxytocin administration during midtrimester-induced abortions is advocated only if it can be carried out under careful observations of an alert nursing staff, aware of the symptoms of water intoxication and instructed to watch the diuresis and report such early signs of the syndrome as asthenia, muscular irritability, or headaches. The oxytocin should be given only in Ringers lactate or, alternately, in Ringers lactate and a 5 per cent dextrose and water solutions. The urinary output should be monitored and the oxytocin administration discontinued and the serum electrolytes checked if the urinary output decreases. The oxytocin should not be administered in excess of 36 hours. If the patient has not aborted by then the oxytocin should be discontinued for 10 to 12 hours in order to perform electrolyte determinations and correct any electrolyte imbalance.
