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:

Phlorizin-induced glycosuria does not prevent gentamicin nephrotoxicity in rats. Because rats with streptozotocin-induced diabetes mellitus (DM) have a high solute diuresis (glycosuria of 10 to 12 g/day), we have suggested that this may in part be responsible for their resistance to gentamicin-induced acute renal failure (ARF). The protection from gentamicin nephrotoxicity was studied in non-diabetic rats with chronic solute diuresis induced by blockage of tubular glucose reabsorption with phlorizin (P). DM rats with mild glycosuria (similar in degree to that of the P treated animals) were also studied. Unanesthetized adult female, Sprague-Dawley rats were divided in four groups and studied for 15 days. Group 1 (P alone) received P, 360 mg/day, for 15 days; Group II (P + gentamicin); Group III (gentamicin alone) and Group IV (mild DM + gentamicin). Nephrotoxic doses (40 mg/kg body wt/day) of gentamicin were injected during the last nine days of study to the animals of groups II to IV. In Group I, P induced a moderate and stable glycosuria (3.9 +/- 0.1 g/day, SE), and no functional or morphologic evidence of renal dysfunction (baseline CCr 2.1 +/- 0.1 ml/min, undetectable lysozymuria) or damage (tubular necrosis score [maximum 4], zero). In Group II, P did not prevent gentamicin-ARF (maximal decrease in CCr at day 9.89%, P less than 0.001; peak lysozymuria, 1863 +/- 321 micrograms/day; and tubular necrosis score, 3.9 +/- 0.1). These values were not different from those of Group III: maximal decrease in CCr 73% (P less than 0.001); lysozymuria, 2147 +/- 701 micrograms/day; tubular necrosis score, 3.8 +/- 0.1.(ABSTRACT TRUNCATED AT 250 WORDS)
