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:

Anxiogenic potential of ciprofloxacin and norfloxacin in rats. INTRODUCTION: The possible anxiogenic effects of fluoroquinolones, namely ciprofloxacin and norfloxacin, were investigated in adult Charles Foster albino rats of either sex, weighing 150-200 g. METHODS: The drugs were given orally, in doses of 50 mg/kg for five consecutive days and the experiments were performed on the fifth day. The tests included open-field exploratory behaviour, elevated plus maze and elevated zero maze, social interaction and novelty-suppressed feeding latency behaviour. RESULTS: The results indicate that ciprofloxacin- and norfloxacin-treated rats showed anxious behaviour in comparison to control rats in all the parameters studied. However, ciprofloxacin- and norfloxacin-treated rats did not differ significantly from each other in various behavioural parameters. CONCLUSION: The present experimental findings substantiate the clinically observed anxiogenic potential of ciprofloxacin and norfloxacin.
