ABSTRACT
<p><b>OBJECTIVE</b>To compare the efficacy of 3% hypertonic saline solution with 20% mannitol in treatment of intracranial hypertension in patients with aneurysmal subarachnoid hemorrhage.</p><p><b>METHODS</b>An alternating treatment protocol was used to compare the efficacy of 160 mL 3% hypertonic saline solution (HSS) with 150 mL 20% mannitol for episodes of increased intracranial pressure (ICP) in patients with aneurysmal subarachnoid hemorrhage. The dependent variables were the extent and duration of reduction of increased ICP after each event.</p><p><b>RESULTS</b>Both 3% HSS and 20% mannitol rapidly decreased the ICP in patients with aneurysmal subarachnoid hemorrhage (P <0.01). No difference between two medications in the extent of duration of ICP and reduction of action (P >0.05).</p><p><b>CONCLUSION</b>3% HSS should be considered as the first-line osmotic drug in treatment of intracranial hypertension in patients with aneurysmal subarachnoid hemorrhage.</p>

<p><b>OBJECTIVE</b>To investigate the expression of nerve growth factor (NGF) and glial cell line-derived neurotrophic factor (GDNF) in monkeys of resuscitation after selective cerebral ultraprofound hypothermia and blood flow occlusion.</p><p><b>METHODS</b>The monkeys were immediately removed brain after death in operation of group A (identical temperature perfusion group) and group B (ultraprofound hypothermia perfusion group). Immunohistochemical technique was used to determine frontal cellular expression of NGF and GDNF. Statistics were analyzed by ANOVA analyses with significance level at P < 0.05.</p><p><b>RESULTS</b>The expressions of NGF and GDNF in the group B were significantly higher than those in the group A (P < 0.05).</p><p><b>CONCLUSION</b>NGF and GDNF increased significantly in the monkeys of resuscitation after selective cerebral ultraprofound hypothermia and blood flow occlusion. It may be a protective mechanism for neuron survival and neural function recovery.</p>
