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:

Gentamicin nephropathy in a neonate. The clinical and autopsy findings in a premature baby who died of acute renal failure after therapy with gentamicin (5 mg/kg/day) and penicillin are presented. The serum gentamicin concentration had reached toxic levels when anuria developed. Numerous periodic acid Schiff (PAS) positive, diastase resistant cytoplasmic inclusion bodies which appeared as myelin figures in cytosegresomes under the electron microscope were identified in the proximal convoluted tubules. The pathological changes induced by gentamicin in the human neonatal kidneys have not been previously reported.
