A hypothesis: hydrogen sulfide might be neuroprotective against subarachnoid hemorrhage induced brain injury.

Gases such as nitric oxide (NO) and carbon monoxide (CO) play important roles both in normal physiology and in disease. Recent studies have shown that hydrogen sulfide (H2S) protects neurons against oxidative stress and ischemia-reperfusion injury and attenuates lipopolysaccharides (LPS) induced neuroinflammation in microglia, exhibiting anti-inflammatory and antiapoptotic activities. The gas H2S is emerging as a novel regulator of important physiologic functions such as arterial diameter, blood flow, and leukocyte adhesion. It has been known that multiple factors, including oxidative stress, free radicals, and neuronal nitric oxide synthesis as well as abnormal inflammatory responses, are involved in the mechanism underlying the brain injury after subarachnoid hemorrhage (SAH). Based on the multiple physiologic functions of H2S, we speculate that it might be a promising, effective, and specific therapy for brain injury after SAH.

Giant aneurysm of the basilar artery in an 86 year old woman.

In this article we present an 80 year old female patient with an unruptured giant aneurysm of the basilar artery presenting with posterior circulation ischemic symptoms. Angiography and CT revealed giant basilar aneurysmal dilatation with severe and wide intracranial arteriosclerosis. We described the uniqueness of this case. Giant basilar aneurysm is associated with various complications particularly brain stem infarction. It is emphasized that arteriosclerosis plays an important role in the formation of giant basilar aneurysms.

[Progress of studies on the mechanism of acupuncture treatment of acute ischemic cerebral stroke].

In the present paper, the authors review the current development of studies on mechanisms of acupuncture treatment of acute ischemic cerebral apoplexy from (1) blood rheology, (2) cerebral microcirculation, 3) metabolism of cerebral tissue, (4) cerebral electrical activity, (5) free radicals and lipid peroxidation reaction, (6) excitatory aminoacid, (7) calcium overload, (8) nitrogen monoxidum, and (9) cerebral apoptosis. Cerebral stroke includes ischemic stroke and hemorrhagic stroke. Ischemic cerebral stroke accounted for about 60%-70% of all the stroke cases. At present, the main remedies for treating acute ischemic cerebral stroke includes thrombolysis, anti-platelet aggregation, improving microcirculation and symptomatic therapy. In stroke, highlighting the efficacy of acupuncture therapy in the treatment of stroke.
