Hemodynamic (central venous pressure, cardiac index, mean arteria

Hemodynamic (central venous pressure, cardiac index, mean arterial pressure, heart rate, stroke volume index, systemic vascular resistance index, global end-diastolic index, intrathoracic blood index and extravascular lung water index), biochemical (serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvate transaminase (SGPT), alkaline phosphatase (ALP), gamma-glutamyl transpeptidase PD0325901 supplier (gamma-GT), urea and creatinine) and inflammatory (tumour necrosis factor-alpha, interleukin

(IL)-6, IL-10 and C-reactive protein) parameters were measured.

(a) Hemodynamics: The increase of central venous pressure monitoring and heart rate and the decrease of cardiac index, mean arterial pressure, stroke volume index, global end-diastolic volume index and intrathoracic blood

volume index with the establishment of pneumoperitoneum were attenuated by IP. Systemic vascular resistance index and extravascular lung water were not affected. (b) Urea significantly increased with the pneumoperitoneum. IP, however, attenuated this effect. IYther biochemical parameters (SGOT, SGPT, ALP, gamma-GT and creatinine) had a similar upward trend during IAH, which was reversed with IP. (c) Inflammatory parameters: CRP was increased with pneumoperitoneum, an effect that was attenuated with the application of IP. Ieo significant differences were observed for interleukins.

“Yangtze River estuary is one of the largest estuaries worldwide. In this study, the sediment quality of Yangtze River estuary was evaluated using zebrafish (Danio rerio) embryos. Freshly fertilized zebrafish eggs (2 h after fertilization) were exposed to the whole sediment and its organic phase of extract, respectively. The parameters, including survival rate, RXDX-101 nmr abnormality, hatching rate, and heart rate of the zebrafish embryos, were recorded during the 96-h exposure. The results demonstrated that the concentrations of heavy metals (Zn, Cu, Cd, Ni, Cr, and As) and low-molecular weight PAHs (Fluorene) in the sediment of Yangtze River estuary exceeded their corresponding effects range low values. The maximum concentrations of Zn and Fluorene in the sediment samples were 239.6 mu g/g and 45.9 ng/g, respectively. In both whole sediment test and organic extract test, the survival rate and heart rate of zebrafish embryos were reduced, as well as abnormalities and delayed hatching were induced. For example, the highest mortality of the embryos was 39% in the whole sediment exposure. Overall, the occurrence of toxic compounds in the sediment of Yangtze River estuary may have potentially teratogenic effect on biota.
