Lipid Emulsion Restoration of Myocardial Contractions After Bupivacaine-Induced Asystole In Vitro: A Benefit of Long- and Medium-Chain Triglyceride Over Long-Chain Triglyceride.

Background: The relative efficacies of a long- and medium-chain triglyceride (LCT/MCT) emulsion and an LCT emulsion for treatment of bupivacaine (BPV)-induced cardiac toxicity are poorly defined.

Methods: After inducing asystole by BPV, varied concentrations (1%-12%) of either LCT/MCT (Lipofundin; B. Braun, Melsungen, Germany) or LCT emulsion (Intralipid; Fresenius Kabi, Upsala, Sweden) were applied to observe the recovery of stimulated contractile responses and contractile forces in either a recirculating or washout condition for 60 minutes, using guinea pig papillary muscles.

Intralipid Restoration of Myocardial Contractions Following Bupivacaine-Induced Asystole: Concentration- and Time-Dependence In Vitro.

Background: The concentration- and time-response relationships of lipid emulsion (LE; Intralipid) on the recovery of myocardial contractility following bupivacaine (BPV)-induced asystole are poorly defined.

Methods: After achieving asystole by 500-μM BPV, varied concentrations of LE were applied to determine the recovery of stimulated contractile responses and contractions in the cardiac tissues of guinea pigs at a 1.2-Hz stimulation rate.

Expression of human β-defensin-2 in the prostate.

Objective: To investigate the expression and regulation of human β-defensin-2 (HBD-2) in the prostate.

Patients And Methods: Normal human prostate epithelial cell line (RWPE-1), human prostate cancer cell lines (DU-145, PC-3), and paraffin-embedded prostate tissue from patients with benign prostatic hyperplasia (BPH) were analysed by RT-PCR and immunohistochemical staining. HBD-2 expression was also analysed by RT-PCR and ELISA in RWPE-1 cells treated with lipopolysaccharide (LPS).
