[Comparison of radial two-dimensional strain and regional wall motion abnormalities in the patients undergoing off-pump coronary artery bypass grafting].

Background: Measurement of myocardial strain by echocardiogram is a novel approach in quantitatively assessing regional ventricular function. We investigated the relationship between left ventricular radial strain and traditional visual assessment of regional wall motion abnormalities.

Methods: We obtained midesophageal short-axis view of the left ventricle at the level of papillary muscles with a transesophageal echocardiography in 32 patients before and after off-pump coronary artery bypass grafting.

Differential localization and regulation of stargazin-like protein, gamma-8 and stargazin in the plasma membrane of hippocampal and cortical neurons.

Transmembrane AMPA receptor regulatory proteins (TARPs), including stargazin/gamma-2, are associated with AMPA receptors and participate in their surface delivery and anchoring at the postsynaptic membrane. TARPs may also act as a positive modulator of the AMPA receptor ion channel function; however, little is known about other TARP members except for stargazin/gamma-2. We examined the synaptic localization of stargazin/gamma-2 and gamma-8 by immunoelectron microscopy and biochemical analysis.

[Comparison of propofol LCT and propofol MCT/LCT regarding the injection pain at different sites and the memory].

Background: Incidence and intensity of pain on intravenous injection of propofol LCT were compared with those of propofol MCT/LCT.

Methods: Eighty adult patients scheduled to receive general anesthesia were divided into two groups, propofol LCT (Group L, AstraZeneca) and propofol MCT/LCT (Group M, Maruishi Pharmaceutical). The peripheral vein was inserted with an 18 gauge intravenous catheter at the dorsal hand, the wrist, or the anterior brachial region.

General anesthesia for patients with Brugada syndrome. A report of six cases.

Purpose: To review six cases of Brugada syndrome presenting for insertion of a cardioverter-defibrillator under general anesthesia.

Clinical Features: All patients had a history of syncope, ST segment elevation in the right precordial lead of the electrocardiogram (ECG) which became prominent after a pilsicainide challenge test. Routine monitors, right precordial lead of the ECG and an external defibrillator were installed prior to anesthesia.

[Two tracheal tubes inserted for endotracheal tube replacement in a patient with severe obstructive sleep apnea: a case report].

A 34-year-old obese, small-jawed and short-necked woman, had severe obstructive sleep apnea syndrome (OSAS) with bronchial asthma. A surgical removal of a lingual tumor using a laser knife was scheduled under general anesthesia with sevoflurane. A small diameter tracheal tube for laser surgery (internal diameter (ID) of 5.
