  Animals Sprague-Dawley dams (n = 48) had normal vaginal births and on the day of birth (PND 0), each litter was separated by sex, and four males and four females were randomly selected so that each litter was culled to eight. The dams with their natural litters (culled to four/sex/litter) were obtained on PND 0 from the breeding colony at the National Center for Toxicological Research (NCTR/FDA). Each dam was individually housed in a standard polycarbonate cage lined with wood chip bedding and provided with ad libitum food (NIH-31, Purina Mills, St Louis, MO) and water. The colony room was maintained at 22°C ± 1°C (mean ± SE) and 45–55% humidity on a 12-h light/dark cycle (7:00 a.m.–7:00 p.m.). Each pup was paw tattooed on PND 1 and also identified with a nontoxic marker on the dorsal side and tail tip on PND 4.

  Home cage pup behavior. Data from the five observation times on PND 7 (8:00 a.m., 10:00 a.m., 12:00 p.m., 2:00 p.m., and 4:00 p.m.) were analyzed separately from the single observation time on PNDs 8–11 (12:00 p.m.). Six behaviors were categorized as abnormal activity: fast activity, paddling, partial paddling, paresis, partial paresis, wall climbing. To analyze abnormal activity, each pup at each observation at each time was assigned a “1” if it exhibited any of the six abnormal behaviors or a “0” for any other behavior. Generalized linear models with a log link and Poisson distribution were used to analyze the counts for each of the two data sets (PND 7 only and PNDs 8–11) with factors of treatment, observation time (e.g., 8:00 a.m., 10:00 a.m.) (PND 7 analysis only), minutes posttreatment (e.g., 5, 14, 23, or 32 min), and sex.

  Slant board behavior. Each pup could exhibit one of three outcomes: a successful turn within 60 s, a fall from the apparatus within 60 s, or an incomplete turn. A failure was categorized as a fall or an incomplete turn.

To analyze the latency to turn time, a Cox Proportional Hazards model was run in SAS (SAS Version 9.1; SAS Institute Inc.) using treatment, sex, and PND as factors. Pups that fell or did not complete the turn were accounted for in this analysis by adjusting the empirical distribution function.

  We exposed postnatal day 7 (P7) Sprague-Dawley rats of both sexes to one of four treatment protocols: (i) sham controls (mock GA-vehicle, 0.1% dimethyl sulfoxide+21% oxygen for 6 h); (ii) GA-treated (midazolam, 9 mg kg−1, i.p.; single injection immediately before administration of 0.75% isoflurane+75% nitrous oxide+24% oxygen for 6 h); (iii) GA+PPX-treated (PPX, 1 mg kg−1 i.p.; four doses—at 9 h before, immediately before, immediately after, and 9 h after 6 h of GA); and (iv) PPX alone (same dosing regimen but mock GA). At the end of the treatments, rat pups were reunited with their mothers. Rats were housed using standard housing on a 12 h light/dark cycle with ad libitum access to food and water. All experiments were approved by the Animal Care and Use Committee of the University of Virginia Health System and were done in accordance with the Public Health Service's Policy on Human Care and Use of Laboratory Animals. All efforts were made to minimize the number of animals used.

  R(+)PPX doses and the dosing regimen were selected based on results from our prior work7 and the half-life of R(+)PPX which is estimated to be 8–12 h9 [i.e. R(+)PPX was dosed ∼every half-life around the time of anaesthesia exposure]. An adult rodent dose of 1 mg kg−1 is equivalent to a human dose of 0.2 mg kg−1.9 10 Thus, these doses are very small and clinically feasible. Based on high-pressure liquid chromatography assays, R(+)PPX was >99.9% chemically and >99% enantiomerically pure.11

  We found no differences among the groups in general appearance or body weight over the next 7 months (data not shown). Cognitive abilities were assessed between 5 and 7 months of age using the Morris water maze test with the adult size pool (180 cm inner diameter).1 To examine their ability to swim, animals were tested in cued trials using a visible platform that was switched to a new location for each trial. During the place trials, rats were tested on their ability to learn the location of a platform (submerged, not visible), which remained in the same location during all trials. Two acquisition place trials were performed, each four blocks long (2 days per block). Probe trials were performed after each acquisition place trial (after blocks four and nine). During these trials, the platform was removed and times and patterns of swimming were analysed with special attention focused on time spent in the target quadrant.

The perfusion lasted for 15–25 min. The brains were removed and incubated overnight in the same fixative. Paraffin blocks of brain tissue (0.5 mm thick) included sections of the hippocampus at different levels along the septotemporal axis and associated areas.29 Coronal hippocampal sections 5 μm in thickness were Nissl-stained, and examined under a light microscope (Nikon ECLIPSE, 50i, Japan) to study the morphological changes of pyramidal neurones in the CA1 and CA3 regions of the hippocampus. We counted cells imaged from three sections per animal (n=3 for each group). Nissl-positive cells were counted only if the structures were of the appropriate size and shape, possessed a Nissl-positive nucleus and cytoplasmic Nissl-positive particles. The number of Nissl-positive neurones in the pyramidal cell layers of the bilateral CA1 regions was counted at ×400 magnification by two individuals in a blinded manner.30 Questionable structures were examined under ×1000 magnification and were not counted if identification remained uncertain.

A0277; Beyotime Institute of Biotechnology; 1:1,000) for 30 min at 37°C, and immunoreactivity was then visualized by addition of a streptavidin-peroxidase complex and 3,3′-diaminobenzidine (both from Beyotime Institute of Biotechnology). Counterstaining was performed with hematoxylin (Zhongshan Golden Bridge, Beijing, China). Subsequent to each incubation step, slices were washed with Tris-buffered saline/Tween 20 three times for 5 min each. All images were captured using an Axioskop fluorescence microscope (Carl Zeiss AG, Oberkochen, Germany).

  Western blotting The preparation of hippocampal tissues for protein extraction was performed as described in previous studies (23,24). Briefly, total proteins were extracted using the radioimmunoprecipitation assay buffer (Beyotime Institute of Biotechnology). The hippocampus tissue proteins were separated by 10% sodium dodecyl sulfate-polyacrylamide gel electrophoresis and then electrotransferred to a nitrocellulose membrane. After blocking with 5% non-fat milk for 1 h at room temperature and being washed three times (10 min each) using 1x TBST, the membrane was incubated with primary antibodies at 4°C overnight and then with horseradish peroxidase-conjugated secondary antibody (Beyotime Institute of Biotechnology) at room temperature for 2 h. The primary antibodies used were as follows: Rabbit anti-cleaved-poly (ADP-ribose) polymerase (PARP) antibody (catalogue no. AP102; 1:200) and rat anti-GAPDH antibody (catalogue no. AG019; 1:5,000; both from Beyotime Institute of Biotechnology). Subsequently, the target proteins were visualized by an enhanced chemiluminescence method (catalogue no. W1001, Promega Corporation, Madison, WI, USA) and analyzed with the Gel Image Documentation System (Wealtec Corp., Sparks, NV, USA). The relative level of PARP was normalized to that of GAPDH, as presented by band intensity.

Voltage-clamp recordings were obtained with Axon patch 200B patch-clamp amplifier (Molecular Devices, Foster City, CA, USA) and Digidata 1440 interface (Molecular Devices, Foster City, CA, USA). After establishing a gigaseal (>2 GΩ), the membrane was broken to form whole-cell configuration. Series resistance and membrane capacitance were routinely compensated by 60–80%, leakage and capacity currents were subtracted on-line using a P/4 protocol. The data were acquired using pCLAMP 10.0 (Molecular Devices, Foster City, CA, USA) running on a computer. Recording signals were low-pass filtered at 2 kHz and digitized at 10 kHz.

  Animals Sprague-Dawley dams (n = 48) had normal vaginal births and on the day of birth (PND 0), each litter was separated by sex, and four males and four females were randomly selected so that each litter was culled to eight. The dams with their natural litters (culled to four/sex/litter) were obtained on PND 0 from the breeding colony at the National Center for Toxicological Research (NCTR/FDA). Each dam was individually housed in a standard polycarbonate cage lined with wood chip bedding and provided with ad libitum food (NIH-31, Purina Mills, St Louis, MO) and water. The colony room was maintained at 22°C ± 1°C (mean ± SE) and 45–55% humidity on a 12-h light/dark cycle (7:00 a.m.–7:00 p.m.). Each pup was paw tattooed on PND 1 and also identified with a nontoxic marker on the dorsal side and tail tip on PND 4. All animal procedures followed the Guide for the Care and Use of Laboratory Animals (National Research Council, 1996) and were approved in advance by the NCTR Institutional Animal Care and Use Committee.

  Home cage pup behavior. Data from the five observation times on PND 7 (8:00 a.m., 10:00 a.m., 12:00 p.m., 2:00 p.m., and 4:00 p.m.) were analyzed separately from the single observation time on PNDs 8–11 (12:00 p.m.). Six behaviors were categorized as abnormal activity: fast activity, paddling, partial paddling, paresis, partial paresis, wall climbing. To analyze abnormal activity, each pup at each observation at each time was assigned a “1” if it exhibited any of the six abnormal behaviors or a “0” for any other behavior. Generalized linear models with a log link and Poisson distribution were used to analyze the counts for each of the two data sets (PND 7 only and PNDs 8–11) with factors of treatment, observation time (e.g., 8:00 a.m., 10:00 a.m.) (PND 7 analysis only), minutes posttreatment (e.g., 5, 14, 23, or 32 min), and sex.

  Slant board behavior. Each pup could exhibit one of three outcomes: a successful turn within 60 s, a fall from the apparatus within 60 s, or an incomplete turn. A failure was categorized as a fall or an incomplete turn. The odds of failure were analyzed using a generalized linear model with repeated measures and a binomial distribution and logit link function. To analyze the latency to turn time, a Cox Proportional Hazards model was run in SAS (SAS Version 9.1; SAS Institute Inc.) using treatment, sex, and PND as factors. Pups that fell or did not complete the turn were accounted for in this analysis by adjusting the empirical distribution function.

  We exposed postnatal day 7 (P7) Sprague-Dawley rats of both sexes to one of four treatment protocols: (i) sham controls (mock GA-vehicle, 0.1% dimethyl sulfoxide+21% oxygen for 6 h); (ii) GA-treated (midazolam, 9 mg kg−1, i.p.; single injection immediately before administration of 0.75% isoflurane+75% nitrous oxide+24% oxygen for 6 h); (iii) GA+PPX-treated (PPX, 1 mg kg−1 i.p.; four doses—at 9 h before, immediately before, immediately after, and 9 h after 6 h of GA); and (iv) PPX alone (same dosing regimen but mock GA). At the end of the treatments, rat pups were reunited with their mothers. Rats were housed using standard housing on a 12 h light/dark cycle with ad libitum access to food and water. All experiments were approved by the Animal Care and Use Committee of the University of Virginia Health System and were done in accordance with the Public Health Service's Policy on Human Care and Use of Laboratory Animals. All efforts were made to minimize the number of animals used.
64
  R(+)PPX doses and the dosing regimen were selected based on results from our prior work7 and the half-life of R(+)PPX which is estimated to be 8–12 h9 [i.e. R(+)PPX was dosed ∼every half-life around the time of anaesthesia exposure]. An adult rodent dose of 1 mg kg−1 is equivalent to a human dose of 0.2 mg kg−1.9 10 Thus, these doses are very small and clinically feasible. Based on high-pressure liquid chromatography assays, R(+)PPX was >99.9% chemically and >99% enantiomerically pure.11
65
  We found no differences among the groups in general appearance or body weight over the next 7 months (data not shown). Cognitive abilities were assessed between 5 and 7 months of age using the Morris water maze test with the adult size pool (180 cm inner diameter).1 To examine their ability to swim, animals were tested in cued trials using a visible platform that was switched to a new location for each trial. During the place trials, rats were tested on their ability to learn the location of a platform (submerged, not visible), which remained in the same location during all trials. Two acquisition place trials were performed, each four blocks long (2 days per block). Probe trials were performed after each acquisition place trial (after blocks four and nine). During these trials, the platform was removed and times and patterns of swimming were analysed with special attention focused on time spent in the target quadrant.
66

  Sevoflurane-treated (n=6) and air-treated (n=6) rats (P7–8, 16–17 g) were killed for the Nissl staining at 6 h after a 6 h exposure to either sevoflurane or air. Animals were anaesthetized with a lethal dose of 10% chloral hydrate and transcardially perfused with saline through the left cardiac ventricle until the liver and lungs were cleared of blood, followed by 4% paraformaldehyde in 0.1 M PB (NaH2PO4.2H2O 2.96 g, Na2HPO4.12H2O 29 g dissolved in 1000 ml water, PH 7.4). The perfusion lasted for 15–25 min. The brains were removed and incubated overnight in the same fixative. Paraffin blocks of brain tissue (0.5 mm thick) included sections of the hippocampus at different levels along the septotemporal axis and associated areas.29 Coronal hippocampal sections 5 μm in thickness were Nissl-stained, and examined under a light microscope (Nikon ECLIPSE, 50i, Japan) to study the morphological changes of pyramidal neurones in the CA1 and CA3 regions of the hippocampus. We counted cells imaged from three sections per animal (n=3 for each group). Nissl-positive cells were counted only if the structures were of the appropriate size and shape, possessed a Nissl-positive nucleus and cytoplasmic Nissl-positive particles. The number of Nissl-positive neurones in the pyramidal cell layers of the bilateral CA1 regions was counted at ×400 magnification by two individuals in a blinded manner.30 Questionable structures were examined under ×1000 magnification and were not counted if identification remained uncertain.

  Immunohistochemical assay Following sacrifice, the entire rat brain was rapidly removed, washed with phosphate-buffered saline, incubated for at least 48 h in 4% paraformaldehyde (Sigma-Aldrich; Merck, Darmstadt, Germany) and embedded in paraffin. Next, the paraffin-embedded tissues were sectioned into 4-µm slices, and sections with the hippocampus structure were used for immunohistochemical analyses. Slices were incubated with rabbit anti-caspase-3 primary antibody (Catalogue no. AC030; Beyotime Institute of Biotechnology; 1:200) at 4°C overnight, then incubated with biotinylated anti-rabbit secondary antibody (catalogue no. A0277; Beyotime Institute of Biotechnology; 1:1,000) for 30 min at 37°C, and immunoreactivity was then visualized by addition of a streptavidin-peroxidase complex and 3,3′-diaminobenzidine (both from Beyotime Institute of Biotechnology). Counterstaining was performed with hematoxylin (Zhongshan Golden Bridge, Beijing, China). Subsequent to each incubation step, slices were washed with Tris-buffered saline/Tween 20 three times for 5 min each. All images were captured using an Axioskop fluorescence microscope (Carl Zeiss AG, Oberkochen, Germany).

  Western blotting The preparation of hippocampal tissues for protein extraction was performed as described in previous studies (23,24). Briefly, total proteins were extracted using the radioimmunoprecipitation assay buffer (Beyotime Institute of Biotechnology). The hippocampus tissue proteins were separated by 10% sodium dodecyl sulfate-polyacrylamide gel electrophoresis and then electrotransferred to a nitrocellulose membrane. After blocking with 5% non-fat milk for 1 h at room temperature and being washed three times (10 min each) using 1x TBST, the membrane was incubated with primary antibodies at 4°C overnight and then with horseradish peroxidase-conjugated secondary antibody (Beyotime Institute of Biotechnology) at room temperature for 2 h. The primary antibodies used were as follows: Rabbit anti-cleaved-poly (ADP-ribose) polymerase (PARP) antibody (catalogue no. AP102; 1:200) and rat anti-GAPDH antibody (catalogue no. AG019; 1:5,000; both from Beyotime Institute of Biotechnology). Subsequently, the target proteins were visualized by an enhanced chemiluminescence method (catalogue no. W1001, Promega Corporation, Madison, WI, USA) and analyzed with the Gel Image Documentation System (Wealtec Corp., Sparks, NV, USA). The relative level of PARP was normalized to that of GAPDH, as presented by band intensity.

Caspase-positive and total number of cells were counted in the CA1 region of the hippocampus and the adjacent parietal cortex at 20× magnification. The brain sampled and analyzed in parietal cortex was the same region used in the Western blot from the opposite brain hemisphere. The mean number of cells was calculated from 3 sections per animal and the data expressed as the percentage of caspase-3 positive cells in each region.

  For evaluating synaptogenesis in vivo, 5 sections representing different coronal level of the dentate gyrus were picked randomly from each animal. For each section, 3 images were randomly taken in the dentate gyrus defined by DAPI staining by an experimenter blind to condition. For evaluating synaptogenesis in vitro, 5 neurons were picked randomly from the 4 quadrants and the center of each coverslip. The image of each dendrite segment defined by MAP2 immunolabeling was taken 20 μm apart from the nucleus defined by DAPI immunolabeling. Representative images were taken using a 63 × 1.0 N.A. objective with an additional 5.0x magnification lens under a Leica SP8 confocal microscope (Leica, Wetzlar, Germany), and the settings were consistent for each capture. Synaptic puncta were quantified using ImageJ software (NIH, Bethesda, MD, USA). For evaluating the activation of mTOR signaling in vivo, 5 sections representing different coronal level of the dentate gyrus were picked randomly from each animal by an investigator blind to condition. Images of the dentate gyrus were taken using a 20 × 1.0 N.A. objective with an additional 0.75x magnification lens on a Leica SP8 confocal microscope (Leica, Wetzlar, Germany). For evaluating the activation of mTOR signaling in vitro, 5 fields were picked randomly from the 4 quadrants and center of each coverslip by an investigator blind to condition, and images were taken with a 20 × 1.0 N.A. objective. Cell counts to determine the proportion of cells positive for markers being analyzed were conducted using ImageJ software (NIH, Bethesda, MD, USA). All imaging and analysis were conducted by an investigator blind to the conditions.
