We have developed a reliable and validated radio-enzymatic method for the assay of L-carnitine and acylcarnitines, using a modification of existing methods. The sensitivity of the assay is 10 mumol/l using 10 microliters of plasma or urine. It is also suitable for measurements of carnitine in a 10 mg sample of liver or muscle obtained by percutaneous biopsy. The use of N-ethylmaleimide in the reaction mixture together with an excess of [1-14C]acetyl CoA ensures that the reaction proceeds to completion and a linear response is obtained. Using this method control ranges have been established for plasma and urine carnitine concentrations in healthy children and adults, and for the carnitine content of liver and muscle in adults. No significant difference was found between fasting and post-prandial plasma carnitine levels. An age-related increase was found in urinary total carnitine and acylcarnitine concentration throughout childhood. These data provide a reliable basis for studies of patients with abnormal carnitine and acylcarnitine metabolism, distribution and excretion. 相似文献

One strain each of Escherichia coli and Streptococcus faecalis were exposed to amikacin and ampicillin in combination as well as in succession. Exposure to ampicillin for 1 hr followed by amikacin for 3 or 4 hr had the greatest antibacterial activity when the antibiotics were applied in succession. The least effective exposures for both organisms were 1 hr to amikacin followed by 3 or 4 hr to ampicillin. Exposure to the antibiotics in combination each at 1 MIC had the overall greatest antibacterial activity. Simultaneous exposure to the antibiotic combination does not necessarily mean simultaneous activity of both ampicillin and amikacin on the E. coli. The cell wall autolytic activities produced by ampicillin are triggered within 10 min after physical contact with the bacteria. In contrast, amikacin requires at least 30 min after physical contact to manifest its activity on the ribosome. Although physical exposure to both antibiotics in the combination is simultaneous, the specific activity of each is in fact sequential, with ampicillin acting first. This explains the synergistic effect of the combination. It appears, therefore, that the synergistic or antagonistic affect of a drug combination is determined by the sequence and timing of the antibacterial manifestations of its components. 相似文献

Role of oxidants and antioxidants in atherosclerosis: results of in vitro and in vivo investigations
Siekmeier R Steffen C März W 《Journal of cardiovascular pharmacology and therapeutics》2007,12(4):265-282
Both in vitro and in vivo studies have shown that oxidants are central in the development of atherosclerosis. Consequently, additional studies evaluated the protective effects of various natural and synthetic antioxidants, alone and in combination, with most studies focusing on alpha-tocopherol (vitamin E). Here, we summarize the role of oxidants in the pathomechanism of atherosclerosis. We also discuss epidemiological studies and others focused on the protective effect of vitamin E against atherosclerosis. Other antioxidants are also considered if they were included in studies involving vitamin E. The protective effect of antioxidants on atherosclerotic pathomechanisms has been confirmed in vitro, but only in some animal studies. Various epidemiological and observational studies have produced conflicting results on the protective effect of antioxidants. Most studies of primary or secondary prevention failed to show a protective effect. These conflicting results are biased by a number of factors, including differences between the study groups. Therefore, we describe these studies in detail. 相似文献

The interconversion and extraction of testosterone and androstenedione across and within different tissues or areas have been studied by the constant infusion technique. The results were calculated using the (3)H/(14)C ratios and radioactive concentrations of testosterone and androstenedione obtained from afferent and efferent blood and tissues at equilibrium. In each tissue studied, the interconversion between testosterone and androstenedione inside the tissue was significantly higher than the corresponding interconversion across the tissue. The pulmonary contribution to the total interconversion between testosterone and androstenedione was far more important than that of any of the other tissues studied. The hepatic metabolic clearance rates of testosterone and androstenedione were not different from their metabolic clearance rates in the mesenteric area. The extraction of each of these compounds, although not negligible, was lower in the kidney and the femoral bed compared with the extraction in the liver and the mesenteric area. Finally, with the possible exception of the liver, testosterone and androstenedione were more completely metabolized when they originated from the cells than from afferent blood.The evaluation of these different tissue transfer constants provides more precise information concerning the relative importance of different sites in the metabolism of these interconverting hormones. 相似文献

OBJECTIVE: To study the pharmacokinetics of flunitrazepam (used for sedation in neonates and infants), to determine the influence of both gestational and postnatal age on the pharmacokinetic parameters, and to analyze the relationship between the hemodynamic parameters and flunitrazepam plasma concentration. METHODS: Flunitrazepam was infused for 20 minutes as a single dose (0.2 mg x kg(-1)) and as multiple doses (0.1 mg x kg(-1)). Six to eight 1-mL blood samples were collected per patient. Flunitrazepam plasma concentration was measured by gas chromatography-mass spectrometry. RESULTS: Thirty-one patients (25 neonates and six infants) were included in the study. Only three of them received multiple doses. After the single dose (n = 28), half-life was 22.6 +/- 7.3 hours, clearance was 0.15 +/- 0.14 L x kg x h(-1), and volume of distribution was 4.6 +/- 4.1 L x kg(-1) (mean +/- SD). Plasma clearance and volume of distribution significantly increased with postnatal age (P < .05), but no pharmacokinetic parameter varied significantly with gestational age. Diastolic blood pressure significantly decreased with increasing flunitrazepam plasma concentrations (P < .05). CONCLUSION: Postnatal age but not gestational age influenced flunitrazepam pharmacokinetic parameters in neonates and infants. Diastolic blood pressure was inversely correlated to flunitrazepam plasma concentration. 相似文献
