| 1. | OBJECTIVE/LAY SUMMARY: The objective of this study is to evaluate the effect of acidic Fibroblast Growth Factor (FGF) on the outcome of focal cerebral ischemia in the rat after its administration into the lateral cerebral ventricle. Cerebral ischemia will be induced by a blockade of blood flow in the middle cerebral artery with a filament introduced via common carotid artery. Acidic FGF was previously shown to protect against the loss of cardiac tissue following blood flow restriction in coronary arteries. This study is undertaken to evaluate its plausible brain tissue salvaging properties. |
| 2. | REGULATORY REFERENCE: This study will not be performed under Good Laboratory Practice Regulations. |

| D. | LabChows, Purina Mills, Inc. Rodent Chow Brand will be fed to the animal daily. The lot and expiration will be documented and recorded on file. Chow may differ if specified by sponsor. |
| 6. | TECHNICAL PROCEDURES: The procedures described will be performed in accordance with the Standard Operating Procedures of DaVinci Biomedical Research Prod. Data collected will be documented manually. |
| A. | Body Weights: Individual body weights will be recorded prior to surgery on the surgery form. |
| B. | Fasting of Animals: All animals will be fasted at least 12-24 hours prior to surgery. |
| C. | Preoperative Procedure: |
Anesthesia: Anesthetized will be induced in the chamber filled with isoflurane at 2.5%-4%. After induction anesthesia will be maintained with isoflurane delivered through the nose cone at 0.5-2.5%.
Surgical Preparation: The animal will be clipped over the ventral neck area. The operative area will be cleaned with a three alternating scrubs of povidone-iodine scrub and 70% alcohol, once the alternating scrubs are done a final application of povidone-iodine solution will be applied and allowed to dry (the area will be draped for aseptic surgery).
| D. | Surgical Procedure: The right common carotid (RCCA) will be exposed (midline incision) and isolated. Permanent 3-0 silk will be placed around the external carotid artery (ECA) and the proximal portion of the RCAA. A vessel clip will be placed over the RCCA, proximal to bifurcation of the internal carotid artery and the ECA. A small incision will be made in the RCCA and a 0.30 mm filament (0.3 mm nylon fishing line) will be inserted and secured with 3-0 silk. The RCCA clip will be removed, and the filament advanced into the intracranial ICA 18 mm from ICA/ECA bifurcation. The contralateral CCA will be clamped with a vessel clip for 60 min after the filament was advanced. |
Animal will be placed into the stereotaxic apparatus and small window will be drilled in the skull over the lateral ventricle. Using sterotaxic coordinates a cannula will be placed in the lateral ventricle and 10 microliters of drug will be delivered within 30 seconds. Cannula will be withdrawn, skin incision closed, and animal recovered from anesthesia. Animals will euthanized either 24 hours after surgery (group 3, 4 and 5), or 30 days after surgery (group 1 and 2). Brains will be collected, sliced into 2 mm blocks and stained with 2,3,5-triphenyl tetrazolium chloride. Digital images of slices will be taken and infarct volume calculated using NIH Image software.
