Six animals were sacrificed 72 hours after the first experimental SAH, and the remaining 10 animals were killed 72 hours after the second experimental SAH; ten additional animals served as controls. Basilar arteries were rapidly excised from the dogs and frozen. Multiple segments of the frozen arteries were analyzed independently for total protein and 1,2-diacylglycerol (DAG) content, which averaged 3.17 (\u00b1 0.27 standard error of the mean; SEM) pmol DAG\/\u00b5g protein for all 25 arteries analyzed. A slight decreasing trend in DAG content relative to that of control vessels was found in vessels chronically constricted<jats:italic>in situ<\/jats:italic>by subarachnoid blood clot; however, this trend did not attain statistical significance. Two segments of the same vessels were assayed independently for protein kinase C (PKC) activity, which averaged 1.21 (\u00b1 0.08 SEM) pmol phosphate incorporation per minute per \u00b5g protein for all 24 arteries analyzed. A small decrease in PKC content was noted in vessels that experienced a single SAH; however, PKC returned to near control value in vessels subjected to double SAH. The ratio of particulate (membrane bound) to soluble PKC activity, an indicator of PKC translocation to the membrane and hence PKC activation, showed a small but statistically significant trend to increase with experimental SAH.<\/jats:p>","DOI":"10.3171\/jns.1995.82.5.0834","type":"journal-article","created":{"date-parts":[[2009,6,2]],"date-time":"2009-06-02T17:50:07Z","timestamp":1243965007000},"page":"834-840","source":"Crossref","is-referenced-by-count":17,"title":["Protein kinase C and diacylglycerol content in basilar arteries during experimental cerebral vasospasm in the dog"],"prefix":"10.3171","volume":"82","author":[{"given":"Masayuki","family":"Yokota","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John W.","family":"Peterson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marios C.","family":"Kaoutzanis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenta","family":"Yamakawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Sibilia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicholas T.","family":"Zervas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","first-page":"65","volume-title":"Cerebral Vasospasm.
