Frozen pieces mounted on slides were incubated at 4 C with both the primary 5 HT antibody and the primary 5 HT transporter antibody for 1-6 h and then with both FITC goat anti rabbit IgG and rhodamine X goat anti mouse IgG for 2 h. 5 HT2C immunoreactivity At 15 days post injury, three animals from each group were decapitated without perfusion. Their spinal cords were removed and sections caudal to the lesion site were stained with an antibody Dizocilpine 77086-21-6 for the 5 HT2C receptor. Consecutive 20 um fresh frozen sections were installed on slides and set with cold acetone for 10 min just before being incubated at room temperature with the primary antibody for 24 h, and then with Rhodamine Red Xconjugated AffiniPure donkey anti goat IgG secondary antibody for 2 h. Growing medium was applied. Slides were then located in 4 C after creation under fluorescence microscope. Quantification of immunocytochemical reactions Stained sections were examined under a DMRBE microscope, and images were captured utilizing a DC 330 color camcorder. Photographs were then processed on the Power Mac G4 computer using an IP Lab program to quantitate immunopositive staining. 5 HT and SERT immunoreactivity was quantified at both L2, the level containing aspects of the CPG, and L5, the level containing motor neurons innervating the distal hindlimb, on 6 areas from each animal. Areas of interest in the ventral funiculus, ventral Skin infection horn, dorsalateral portion of the lateral funiculus, and dorsal horn were caught from both sides of the slip. Threshold values were opted for in order that only immunopositive axons and cells were determined. Total labeled pixels were divided by the area of the spot of interest to have mean density per unit area. 5 HT2C immunoreactivity was quantified at L5 on 6 areas from each animal. Images were taken within a fixed package measurement of 768494 pixels at 200. One region of interest in the dorsal horn and two inside the ventral horns were taken on each side on two parts each on four successive slides. The amount of pixels occupied Bazedoxifene P450 inhibitor by buildings within this box was measured. So that only immunopositive structures were tested thresholding values were plumped for from scam lesioned animals and placed on all slides. Complete marked pixels were separated by the sample package size to have mean density per pixel. All drugs were dissolved in sterile saline. Saline was also used whilst the vehicle treatment for behavioral testing. 8 dihydroxy 2di d propylaminotetralin and 1 piperazine hydrochloride were injected 5 min before testing. D fenfluramine was handed 30 min before testing. Carbidopa was injected 30 min before D 5 hydroxtryptamine, which was injected 30 min before testing. All drugs were purchased from Sigma.
