Sprague-Dawley Rat Behavioral Tests

Check if the same lab product or an alternative is used in the 5 most similar protocols

Male Sprague-Dawley rats (7 weeks; Charles River, Yokohama, Kanagawa, Japan) were used for behavioral tests except for a corticosterone (CORT) treatment model in which Male Sprague-Dawley rats (4 weeks old at the beginning of the experiments; Charles River, Yokohama, Japan) were used. The animals were maintained under controlled temperature (23°C ± 3°C) and humidity (50% ± 20%) conditions under a 12-hour-light/-dark cycle (lights on at 7:00 am). Food and water were provided ad libitum. All the studies were performed according to the guidelines of the Taisho Pharmaceutical Co., Ltd. Animal Care Committee and met the Japanese Experimental Animal Research Association standards, as defined in the Guidelines for Animal Experiments. TP0473292, TP0178894, and 1-O-(tricyclo[3.3.1.13,7]decane-1-carbonyl)-β-D-glucopyranuronic acid (TP0478768) were synthesized at the Research Center of Taisho Pharmaceutical Co., Ltd. Adamantane-1-carboxylic acid (TP0037870) and LY379268 were purchased from Tokyo Chemical Industry Co., Ltd. (Tokyo, Japan) and Abcam plc. (Cambridge, UK), respectively. For in vivo studies, TP0473292 was suspended in 0.5% methyl cellulose 400, and LY379268 was dissolved with 0.3% Tween 80.

The present study was approved by the Italian Ministry of Health (Ministero della Salute) (certificate no. 649/2016-PR, 1 July 2016). Experiments were carried out in accordance with local and national guidelines for animal experimentation.
Male Sprague-Dawley (SD) rats aged 8 weeks, weighing 150–200 g, were purchased from the Charles River Laboratories Italia, SRL (Lecco, Italia). All animals were housed under standard laboratory conditions in an animal holding room located at the Department of Biological Sciences and Technologies (Di.S.Te.B.A.), University of Salento (certificate no.48/2004-A). The acclimatization period was not less than one week after delivery. They were fed with standard chow diet and water was provided ad libitum. They were housed in small groups in plastic-bottomed cages containing sawdust. They were bred in a temperature-controlled environment (20 ± 2 °C) with 12 h of light/dark cycles (light from 6:00 a.m. to 6:00 p.m.). At specific time points, they were deeply anesthetized using isoflurane (drop jar method by placing an impermeable mesh grid over the cotton/gauze) and sacrificed through rapid dislocation of the cervical spine.
Body weight, liver weight and Hepatic Index (HI) (percentage of liver weight with respect to body mass) were monitored.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
