- 10:33Conclusion
Målinger af Kv7 (KCNQ) kalium kanal aktivitet i isolerede arterielle myocytter (ved hjælp af patch clamp elektrofysiologiske teknikker) parallelt med målinger af kvælerslange / dilator reaktioner (med tryk myography) kan afsløre vigtige oplysninger om de roller, Kv7 kanaler i vaskulære glatte muskulatur fysiologi og farmakologi.
