Résumé

BACKGROUND: Although cisatracurium has many advantages in anesthetic practices, the best choice of a nondepolarizing neuromuscular blocking agent that can replace succinylcholine is rocuronium. However, it is reported that remifentanil with propofol might provide reliable intubating condition, even without a neuromuscular blocking agent; therefore, it might improve the intubating condition with cisatracurium. This study examined intubating conditions after administering rocuronium or cisatracurium in a rapid sequence induction with remifentanil-propofol. METHODS: Fifty two ASA physical status 1 or 2 adult patients scheduled for an elective surgery were enrolled in a randomized double-blinded trial. Anesthesia was induced in all patients with propofol 2.0 mg/kg and remifentanil 0.5 microgram/kg, administered over 60 seconds. Rocuronium 0.9 mg/kg (3 x ED95, R group, n = 23) or cisatracurium 0.15 mg/kg (3 x ED95, C group, n = 29) was administered after the induction sequence. Laryngoscopy was attempted when the anesthesiologist thought it was 90 seconds after drug administration and appropriate time for intubation. The examiner, another anesthesiologist, recorded the exact time to intubation and suppression of maximal T1 on TOF. The intubating condition was assessed by the first anesthesiologist, as excellent, good, poor or not possible. RESULTS: The best time to laryngoscopy was predicted by measuring TOF and was found to be significantly longer in the C group (197 +/- 53 s) than in the R group (102 +/- 49 s) (P value < 0.05). However, time to larygoscopy, intubating condition during the laryngoscopy, and hemodynamic changes after intubation was similar in both groups. CONCLUSIONS: Despite fundamentally slower onset time, cisatracurium can provide quite good intubating conditions, which were comparable to those achieved with equipotent doses of rocuronium, which is more expensive in anesthesia inducted with remifentanil and propofol.

Résumé

The aim of this study was to examine the hypoglycemic effect of chlorella in 6 week-old type 2 diabetic Goto-Kakizaki (GK, n=30) rats and 6 week-old normal Wistar (n=30) rats. Animals were randomly assigned to 3 groups respectively, and were fed three different experimental diets containing 0%, 3% or 5% (w/w) chlorella for 8 weeks. In diabetic GK rats, the insulinogenic-indices were not significantly different among the groups. The concentrations of fasting plasma glucagon and hepatic triglyceride, and the insulin/glucagon ratios of the GK-3% chlorella and GK-5% chlorella groups were significantly lower than those of the GK-control group. The HOMA-index and the concentrations of fasting blood glucose and plasma insulin of the GK-3% chlorella and GK-5% chlorella groups were slightly lower than those of the GK-control group. In normal Wistar rats, the insulinogenic-indices were not significantly different among the normal groups, but that of the Wistar-5% chlorella group was slightly higher than the other groups. The concentrations of fasting blood glucose and plasma insulin, and the HOMA-index of the Wistar-5% chlorella group were a little higher, and the fasting plasma glucagon concentration and the insulin/glucagon ratio of the Wistar-5% chlorella group were significantly higher than those of the Wistar-control and Wistar-3% chlorella groups. In conclusion, this study shows that the glucose-stimulated insulin secretion was not affected by the intake of chlorella, which could be beneficial, however, in improving insulin sensitivity in type 2 diabetic GK and normal Wistar rats.

Résumé

This study was conducted to investigate the effects of feeding different carbohydrate sources and garcinia cambogia extract (HCA) on body weight and lipid metabolism. Fifty 10-month-old male Sprague-Dawley rats weighting 635 +/- 6 g were randomly divided into 5 groups and fed different experimental diets for 4 weeks. The carbohydrate (CHO) sources of each group were cornstarch (control group, 100% of CHO), fructose (F group and FH group, 25% of CHO) and sucrose (S group and SH group, 25% of CHO). FH group and SH group were fed diets containing 1% (W/W) of HCA. Food intake, body weight gain, and calorie efficiency were not significantly different among the groups. Perirenal fat pad weight of FH group was significantly lower than F group, but epididymal fat pad weight was not different among the groups. Fasting glucose level were not significant among the groups. Plasma lipid profile of FH or SH group was slightly lower than F or S group, respectively. The degree of difference of plasma lipid level was greater between F and FH group than those of between S and SH group. In liver, total lipid, triglyceride and total cholesterol level were slightly higher in F group than S group, and tended to be lower in FH group than F group, but tended to be higher in SH group than S group. Liver citrate lyase activity were not significant among the groups. These results suggest that HCA is potential material for reduction of body weight and improvement of plasma lipid profiles. But, there was no difference between fructose intake with HCA and sucrose intake with HCA in reduction of body weight and lipid metabolism.

Résumé

PURPOSE: The pathophysiological mechanisms of the bladder dysfunction in postmenopausal state are not well understood especially in moleclular level. Therefore we investigated the changes of bladder in female rat following bilateral ovariectomy by proteomic approach. MATERIALS AND METHODS: A total 10 female Sprague-Dawley rats were obtained at 8 weeks of age and randomly divided into 2 groups in each 5 rats; sham operation group as the control group and the bilateral ovariectomy group. Whole urinary bladders of the rats were excised 4 weeks after the beginning of the experiment. Conventional proteomics was performed with high resolution 2-D gel electrophoresis followed by computational image analysis and protein identification using mass spectrometry. RESULTS: Bladder weight was not changed by oophorectomy. A comparison of bladder of ovariectomy group with control showed that 8 proteins; Eukaryotic translation initiation factor 5A was over-expressed, and chaperone grp 75 precursor, guanine deaminase, keratin complex 2, Gelsolin precursor, peroxiredoxin 2, Enol protein and contrapsin-like inhibitor 1 precursor were under-expressed in the oophorectomy group. CONCLUSION: These data suggested that the bilateral oophorectomy might make a bladder to have a cellular apoptosis and a change of contractility in the rat bladder. However more information is needed in human bladder tissue for clinical usage and long-term proteomic changes are needed.
