resection of apical lung tumors in highrisk patients using partial sternotomy surgical management of patients with compromised lung function remains a challenge we describe a technique that uses a partial sternotomy to manage highrisk patients with clinical stage 1 apical lung tumors in our experience with four patients we found this method to be effective quick safe and with good short term outcome lithium found in the total brain and brain lipids after intracranial injection of lithium in mice relation to the observed behavior disorders behavioural disturbances after lithium injection only appear in mice with concentrations above 8 microequivalents per brain below this value no fixation of lithium occurs in the brain at higher concentrations the amount of lithium found in the brain and associated with brain lipids increases gradually to reach a plateau moreover although lithium increases the extraction of proteolipids it does not seem to have an affinity for these compounds
