Local ocular hypothermia was evaluated in experimental open sky vitrectomy, closed vitrectomy, and anterior chamber irrigation and aspiration in 40 albino rabbits (80 eyes). The irrigating balanced salt solution was used at room temperature in control eyes and was cooled to 7 degrees C in experimental eyes. Experimental eyes demonstrated less intraocular bleeding volume, less fibrin production, and less postoperative inflammation. No detectable tissue intolerance to hypothermia was observed on short- or long-term follow-up.

We evaluated the efficacy of cycloheximide, heat stress, NMDA receptor blockade (MK801/AP-5), oxygen--glucose deprivation, hypoxia, hypothermia and TNFalpha preconditioning to protect cortical neurons from in vitro ischemic insults that result in acute necrotic and delayed apoptotic neuronal death. Preconditioning treatments were performed 22--24 h before in vitro ischemia. In vitro ischemia was carried out in 96-well microtitre strip-plates by washing neuronal cultures with a balanced salt solution containing 25 mM 2-deoxy-D-glucose and incubating in an anaerobic chamber. Glutamate receptor blockers were present during in vitro ischemia to induce delayed neuronal death. Cycloheximide, heat stress, MK801 and oxygen--glucose deprivation preconditioning were neuroprotective in both acute and delayed in vitro ischemic neuronal death models. AP-5 preconditioning and a 12 h post-MK801 preconditioning interval protected neurons from acute ischemic neuronal death only. Hypoxia, TNFalpha and hypothermic preconditioning provided no neuronal protection in the in vitro ischemia models. This study has confirmed for the first time that several preconditioning treatments can protect neurons from in vitro ischemia induced acute necrotic and delayed apoptotic neuronal death. In addition, a unique feature of this study is the finding that preconditioning could be induced in near-pure primary cortical neuronal cultures, thus confirming that ischemic tolerance is an intrinsic property of neurons and provides a simplified culture system for identifying neuroprotective proteins.
