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:

Thyroid function and urine-concentrating ability during lithium treatment. It has been suggested that adenylate cyclase inhibition may be important in the development of both nephrogenic diabetes insipidus and hypothyroidism during lithium treatment. We measured serum thyroxine and urine-concentrating ability (Umax) in response to desmopressin (DDAVP) in 85 patients receiving lithium. Hypothyroidism developed in eight patients while they were taking lithium. Impaired Umax was found in both euthyroid and hypothyroid patients while some hypothyroid patients concentrated their urine well. It is concluded that the dominant mechanisms by which lithium exerts these two effects are different.
