Abstract
The interaction of antisense peptide nucleic acid (PNA) with yeast tRNA(Phe) was investigated. A 6-mer PNA complementary to the 3'-terminal sequence including the 73ACCA end hybridized to the tRNA. While the PNA with a single mismatch did not. PNA is a promising candidate for controlling tRNA functions by the sequence-specific hybridization.

Abstract
This study was performed to find the rationale for administering steroids to patients with idiopathic interstitial pneumonia (IIP), which was unlikely to be usual interstitial pneumonia (UIP) but was not surgically biopsied. Among IIP patients in the file of the departments, nine patients who met the following criteria were selected for this study ("non-UIP" group): 1) transbronchial lung biopsy showed dense mononuclear cell infiltration in thickened alveolar septa; 2) chest radiograph and computed tomography showed irregular linear, reticular or ground-glass opacities with alveolar consolidation without honeycombing in the lung base; and 3) spirometry was performed before and after steroid therapy. Ten patients with pathologically confirmed nonspecific interstitial pneumonia ("NSIP" group) were also selected for the comparison. Baseline values and percentage increase of vital capacity (VC) after steroid therapy were plotted. Steroids improved VC in both groups of patients. After 1 yr of steroid therapy, percentage increase of VC in "non-UIP" was 28.8+/-7.7%, which was not significantly different from that in NSIP (30.0+/-11.7%). One "non-UIP" patient and one NSIP patient died after 6.4 and 4.3 yrs of follow-up, respectively. Patients with idiopathic interstitial pneumonia presenting cellular interstitial pneumonia in transbronchial lung biopsy, in addition to radiographic findings not typical for usual interstitial pneumonia, could expect a beneficial effect of steroids without undergoing surgical biopsy.

Abstract
BACKGROUND The aim of our study was to investigate the effect of carbon dioxide pneumoperitoneum on systemic and splanchnic hemodynamics in cirrhotic rats. METHODS Sprague-Dawley rats (n = 80) were used in this study. Liver cirrhosis was induced by thioacetamide administration intraperitoneally (200 mg/kg body weight, twice a week for 16 weeks). The radioactive microsphere method was used to measure systemic and regional hemodynamic parameters before, 1 h after the start, and 1 h after the release of pneumoperitoneum. RESULTS Splanchnic blood flow and cardiac index were significantly depressed during pneumoperitoneum in liver cirrhosis and control groups, but no significant differences were seen between the two groups. In both groups, portal venous inflow decreased and hepatic arterial blood flow increased significantly during pneumoperitoneum. However, during pneumoperitoneum, total hepatic blood flow as a percentage of its value before pneumoperitoneum was lower in cirrhotic rats (71.0%) than in control rats (91.9%) (p <0.05, Mann-Whitney U-test). CONCLUSIONS Carbon dioxide pneumoperitoneum markedly decreases total hepatic blood flow in cirrhotic rats due to the impaired hepatic arterial buffer response. Liver function should be carefully controlled in cirrhotic patients after laparoscopic surgery with pneumoperitoneum.

Abstract
We studied the effect of carbon dioxide (CO2) pneumoperitoneum on the systemic and peritoneal cytokine response in a rat model of intraperitoneal sepsis. After intraperitoneal injection of bacterial lipopolysaccharide (LPS, 10 mg/kg), rats were divided into 3 groups (n = 49 in each group): control (abdominal puncture); CO2 pneumoperitoneum, and laparotomy. Blood and peritoneal lavage fluid (PLF) were sampled at 0, 1, 2, 3, 4, 6, and 8 h after LPS challenge. Blood cell counts, plasma endotoxin level, and the levels of tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), and interleukin-6 (IL-6) in the plasma and PLF were measured. Blood cell counts did not differ between the 3 groups. Plasma endotoxin levels in the pneumoperitoneum group were significantly increased immediately after the procedure (p < 0.05). Although peak plasma TNF-alpha levels in the pneumoperitoneum group were seen immediately after the procedure, other changes in plasma cytokine levels did not differ significantly between the 3 groups. PLF TNF-alpha and IL-1beta levels in the pneumoperitoneum group were significantly lower than levels in the control and laparotomy groups soon after the procedure (p < 0.05). PLF IL-6 levels in the pneumoperitoneum group tended to be lower than those in the laparotomy group. In conclusion, CO2 pneumoperitoneum might induce different responses between systemic and peritoneal cytokines soon after the procedure in a rat model of intraperitoneal sepsis.

Abstract
New carabrane-type sesquiterpene lactones, curcumenolactones A, B, and C, were isolated from the 80% aqueous acetone extract of Zedoariae Rhizoma (Zingiberaceae), together with 41 sesquiterpenes and two diarylheptanoids. The absolute stereostructures of curcumenolactones A, B, and C were determined on the basis of physicochemical evidence, which included nuclear Overhauser effect (NOE) and circular dichroic (CD) spectroscopic analyses. Curcumenone, a principal carabrane-type sesquiterpene from Zedoariae Rhizoma, was found to show potent protective effect on D-galactosamine/lipopolysaccharide-induced acute liver injury in mice. In addition, curcumenolactones A and B and the other constituents showed protective effect on D-galactosamine-induced cytotoxicity in primary cultured rat hepatocytes.

Abstract
The renal handling of cisplatin and its metabolites and the relationship between the pharmacokinetics of these platinum species in the kidney and nephrotoxicity in rats were studied by carrying out pharmacokinetic-pharmacodynamic analysis. Rats received cisplatin intravenously as a bolus (2-10 mgkg(-1)) or by constant infusion (55 and 140 microg min(-1) kg(-1)). After intravenous administration of each platinum species, the platinum concentrations of unchanged cisplatin and its mobile and fixed metabolites were determined separately. Nephrotoxicity was estimated by measuring the blood urea nitrogen (BUN) levels and the sigmoid Emax model was used to determine the relationship between pharmacokinetic parameters and BUN levels 5 days after cisplatin administration. Cisplatin and its mobile metabolites in plasma distributed more rapidly and extensively into the kidney (mean apparent kidney-to-plasma concentration ratios were 2.69 and 7.12 mL (g tissue)(-1), respectively) than into the liver (less than 1 mL (g tissue)(-1)). Concomitant administration of mobile metabolites did not significantly alter the disposition of cisplatin. Nephrotoxicity, estimated by measuring BUN levels, appeared to be related to the plasma concentration of intact cisplatin, not total platinum, because mobile metabolites formed from cisplatin showed little nephrotoxicity. The sigmoid Emax model showed the maximum BUN level reached after cisplatin administration was related to the area under the renal cisplatin concentration-time curve (AUCk).

Abstract
Umami is the term that identifies the taste of substances such as L-glutamate salts, which were discovered by Ikeda in 1908. Umami is an important taste element in natural foods; it is the main taste in the Japanese stock "dashi," and in bouillon and other stocks in the West. The umami taste has characteristic qualities that differentiate it from other tastes, including a taste-enhancing synergism between two umami compounds, L-glutamate and 5'-ribonucleotides, and a prolonged aftertaste. The key qualitative and quantitative features of umami are reviewed in this paper. The continued study of the umami taste will help to further our general understanding of the taste process and improve our knowledge of how the taste properties of foods contribute to appropriate food selection and good nutrition.

Abstract
BACKGROUND Recently, the laparosonic coagulating shears (LCS) have been used widely in laparoscopic surgery. In the current study, the usefulness of LCS for arterial division and hemostasis was examined in porcine arteries. METHODS Porcine arteries of several diameters (1, 3, and 5 mm) were removed and divided using LCS with different blade modes: shear, blunt, and flat. The division time and bursting pressure were registered. Additionally, divided sections stained by the Azan-Mallory method were observed microscopically. RESULTS The division time was dependent on the blade modes used. With the flat mode, the bursting pressure of 5-mm arteries was significantly higher than the bursting pressure with shear and blunt modes. Histologically, cavitation and mild degeneration of the vessel walls occurred adjacent to the cutting edge. CONCLUSION The LCS is a safe and useful device for arterial division and hemostasis for 5-mm arteries if an adequate blade mode is used.
