AIM： To evaluate the safety and feasibility of bone marrow cell （BMC） transplantation in patients with chronic liver disease on the waiting list for liver transplantation. METHODS： Ten patients （eight males） with chronic liver disease were enrolled to receive infusion of autologous bone marrow-derived cells. Seven patients were classified as Child-Pugh B and three as Child-Pugh C. Baseline assessment included complete clinical and laboratory evaluation and abdominal MRI. Approximately 50 mL of bone marrow aspirate was prepared by centrifugation in a ficoll-hypaque gradient. At least of 100 millions of mononuclear-enriched BMCs were infused into the hepatic artery using the routine technique for arterial chemoembolization for liver tumors. Patients were followed up for adverse events up to 4 mo. RESULTS： The median age of the patients was 52 years （range 24-70 years）. All patients were discharged 48 h after BMC infusion. Two patients complained ofmild pain at the bone marrow needle puncture site. No other complications or specific side effects related to the procedure were observed. Bilirubin levels were lower at 1 （2.19 ± 0.9） and 4 mo （2.10 ± 1.0） after cell transplantation that baseline levels （238 ± 1.2）. Albumin levels 4 mo after BMC infusion （3.73 ± 0.5） were higher than baseline levels （3.47 ± 0.5）. International normalized ratio （INR） decreased from 1.48 （SD = 0.23） to 1.43 （SD = 0.23） one month after cell transplantation. CONCLUSION： BMC infusion into hepatic artery of patients with advanced chronic liver disease is safe and feasible. In addition, a decrease in mean serum bilirubin and INR levels and an increase in albumin levels are observed. Our data warrant further studies in order to evaluate the effect of BMC transplantation in patients with advanced chronic liver disease.

Sugammadex in the Management of Sinus Tachycardia after Rocuronium Administration: A Case Report

引用

Open Journal of Anesthesiology 2014年第9期4卷 203-206页

作者： Eduardo Fernandes Orioli Guimaraes Muriel Mofreita Saldanha Tiago Coelho fortes Marcelo Grisolia marcos Lopes de Miranda Carlos Darcy Alves Bersot Department of Anesthesia Lagoa Federal HospitalRio de JaneiroBrazil

In rare cases, rocuronium has been associated with dose-related tachycardia, probably by a cardiac muscarinic M2 receptor blockade mechanism. We report the case of a 30-year-old female who underwent excision of a branchial cyst under general anesthesia. This patient presented an episode of sinus tachycardia (130 bpm) shortly after anesthesia induction with propofol, sufentanyl, and rocuronium. Tachycardia could not be explained by any cause other than the use of rocuronium, which was reverted with sugammadex. Two minutes after sugammadex administration, heart rate normalized, corroborating our hypothesis that rocuronium induced the sinus tachycardia observed in our patient. The patient recovered well from the anesthetic-surgical procedure and showed no further cardiovascular, ventilatory, or neurological changes, being transferred to the post-anesthesia care unit, and finally discharged to the ward.

The extraction of essential oils was performed by using the technique of hydrodistillation modified Clevenger apparatus, identification and quantification of the constituents was achieved by Gas Chromatography coupled to Mass Spectrometry, and Gas Chromatography equipped with a flame ionization detector. Assessment of allelopathic activity was evaluated with the use of the method that assesses the direct contact of essential oils on germination and vigor of lettuce seeds. The major constituents that characterize the essential oil from the flowers of Callistemon viminalis were 1, 8-cineole, α-pinene and limonene at concentrations of 66.9%, 16.0% and 10.0%, respectively. The essential oil presented allelopathic activity at intensities that varied proportionately to the concentration of the essential oil, with a reduction in the percentage of germination and the germination speed index (GSI) of lettuce seeds and in the dry mass and length of shoots and roots of lettuce seedlings.
