Impact of 6% Starch 130/0.4 and 4% Gelatin Infusion on Kidney Function in Living-Donor Liver Transplantation.

Background: Since the first liver transplantation, pretransplantation or post-transplantation renal problems are still among the main causes of mortality and morbidity. The aim of this study was to evaluate the effects of fluid replacement solutions used intraoperatively on renal functions in elective living-donor liver transplantation.

Methods: After Ethics Committee approval, informed consents were obtained from patients.

A comparison of the effects of ketamine and remifentanil on renal functions in coronary artery bypass graft surgery.

We have investigated the effects of ketamine-based and remifentanil-based anesthetic protocol on perioperative serum cystatin-C levels, and creatinine and/or cystatin-C-based eGFR equations in terms of acute kidney injury in coronary artery bypass graft (CABG) surgery. Using a simple randomization method (coin tossing), patients were divided into the two groups and not-blinded to the anesthetist. Remifentanil-midazolam-propofol or ketamine-midazolam-propofol-based anesthetic regimen was chosen.

Inhibitory actions of hydroxocobalamin, cyanocobalamin, and folic acid on the ultraviolet light-induced relaxation of the frog upper oesophageal strip.

The applications of ultraviolet (UV) light (336 nm) on the upper oesophageal strips of frog elicited relaxant responses in the presence of NaNO2 (50 microM). The tissues were mounted under the tension 0.5 g in an organ bath containing Ringer solution, maintained at 25 degrees C and gassed with 100% O2.

Restorative effects of zinc and selenium on nitrergic relaxations impaired by cadmium in the mouse corpus cavernosum.

We investigated whether Cd2+ intake (in drinking water, 15 ppm) for 30 days can affect the nitrergic relaxations of the mouse corpus cavernosum (CC) and whether Zn2+ (25 mg kg(-1) via a stomach tube at 48-h intervals) or sodium selenate (8 microg kg(-1) day(-1) intraperitoneally) has a restorative action on the impairment in the response. Relaxant responses of the CC obtained from Cd2+-treated mice to electrical field stimulation (neurogenic) or acetylcholine (endothelium dependent) were significantly inhibited. A partial restoration was observed in the nitrergic relaxation of the CC obtained from Zn2+- or sodium selenate-co-treated animals.

A possible role of S-nitrosothiols at the nitrergic relaxations in the mouse corpus cavernosum.

Relaxations induced by electrical field stimulation and acetylcholine were compared with those induced by acidified sodium nitrite, sodium nitroprusside, S-nitrosoglutathione and S-nitroso-N-acetyl-D,L-penicillamine in the mouse corpus cavernosum precontracted with phenylephrine. NG-nitro-L-arginine inhibited electrical field stimulation- or acetylcholine-induced relaxation, but was ineffective on relaxations caused by the other stimuli. Hydroquinone and pyrogallol had no inhibitory action on the relaxations caused by any stimulus except acidified sodium nitrite.

The effect of Ba2+ on the nitrergic mechanism in the isolated frog lung preparation.

1. The present study was undertaken to investigate effects of Ba2+ on the isolated frog lung strips depolarized by 20 mM K+ in Ca2+ free Ringer solution. 2.

An in vitro study of nonadrenergic-noncholinergic activity on the cavernous tissue of mouse.

The relaxant effects of electrical field stimulation (EFS) and exogenously applied acetylcholine (ACh) or acidified NaNO2 (a-NaNO2) were investigated in the isolated mouse corpus cavernosum precontracted with phenylephrine hydrochloride (PE). Tetrodotoxin (TTX) blocked the relaxant effects of EFS completely, whereas it had no effect on the responses to ACh or a-NaNO2. Guanethidine and indomethacin failed to affect the electrically or ACh-induced relaxations.
