The reaction of two compounds, hypochlorous acid and a mixture of hydrogen peroxide and sulfuric acid, was investigated by applying them to the surface of copper plates, respectively. Hypochlorous acid was produced using two methods. The first hypochlorous acid was prepared by adding one drop of hydrochloric acid to a bleach solution containing sodium hypochlorite. The second hypochlorous acid was prepared through chlorine gas. Through X-ray analysis, the black substance produced by adding one drop to a bleach solution was identified as copper(II) oxide, whereas copper(I) chloride was also found on the copper. The black substance found on the copper plate from the mixture of hydrogen peroxide and sulfuric acid was assumed to be copper(II) oxide by chemical analysis.

We report two cases of pregnant females presenting with intracerebral hematoma caused by ruptured arteriovenous malformation (AVM). A 21-year-old woman suddenly presented with severe headache, motor aphasia and right hemiparesis at 30 weeks of pregnancy because of a hematoma in the left frontal lobe. A cerebral angiogram showed AVM in the frontal lobe. We performed an emergency operation to remove the hematoma and AVM. The postoperative course was uneventful without neonatal complications. In the other case, a 32-year-old woman complained of headache and vomiting at 11 weeks of pregnancy. A CT scan indicated a right cerebellar hematoma. A cerebral angiogram revealed cerebellar AVM. An emergency surgical evacuation of the hematoma and AVM was performed. A complete cure was achieved after operation without complications. Intracerebral hematoma in a pregnant woman can lead to the death of the mother and fetus. Appropriate diagnosis and treatment should be immediately undertaken to save maternal and neonatal life.
