    Notes: Summary Methotrexate (MTX) in serum was measured by RIA in 12 cancer patients receiving high doses of MTX (2 to 8 g/m2) in 6 hour infusions 69 treatments were studied. The peak serum level was proportional to the dose administered and was always greater than 10−4 M. 2 elimination phases were seen: the first had a mean half-life of 2.36 h and the second a mean half-life of 16.14 h. 24 hours after beginning the infusions there were very large variations in individual serum concentrations of MTX, from 2.4 10−6 M to 1.9 10−5 M by 24 h after 8 g/m2. To control these variations, a mathematical model for prediction of the individual pharmacokinetic pattern of a 6 hour-infusion of high-dose MTX by kinetic analysis of a low-test dose is proposed. A program was created for an Apple III computer using toxic and therapeutic serum levels of MTX selected by the clinician. The computer program is adaptable to any infused substance for variable infusion times, thus introducing new advances over existing methods.

    Notes: Summary Peripheral blood glucose, plasma insulin and C-peptide levels were investigated after giving a standardized breakfast (500 kcal, 60g carbohydrates) to 10 nonobese Type 2 diabetic patients previously treated by diet alone. Each patient received at random, at 1 week intervals, either 5 mg glipizide (meal + glipizide) or a placebo (meal alone) 30 min before breakfast. Basal values of blood glucose, plasma insulin and C-peptide were similar on both occasions. After meal + glipizide, the blood glucose increase was sharply limited whereas the rise in plasma insulin was steeper and reached twice as high a level. In contrast, the rise in plasma C-peptide was similar in both conditions. Consequently, the areas under the curves (0–300 min) showed a marked reduction in blood glucose after meal + glipizide (2289±149 versus 3101±169 mmol·min/l; 2p〈0.001), associated with a significant increase in plasma insulin (14219±3261 versus 7591±1173 µU·min/ml; 2p〈0.025) but no significant change in plasma C-peptide (342±45 versus 326±34 pmol·min/ml; N.S.). The insulin/C-peptide molar ratio was thus significantly increased after meal + glipizide (0.41±0.06 versus 0.23±0.04 at the 60th min; 2p〈0.02). The dissociation between the responses of insulin and C-peptide suggests that a single dose of 5 mg glipizide in Type 2 diabetic subjects may enhance availability of peripheral insulin by extrapancreatic mechanism(s). This phenomenon may result in a higher circulating level of the hormone and therefore represent a further mode of action of sulphonylureas. Finally, the usual concept that peripheral insulin levels reflect true insulin secretion may be misleading in studies dealing with sulphonylureas.

    Notes: Summary The diuretic effects of torasemide and of furosemide were compared in a double blind cross-over study in 13 patients with stable chronic heart failure. Single doses of 10 mg and 20 mg of torasemide and of 40 mg of furosemide were given orally, in a randomized order on 3 consecutive days. In addition, a placebo was administered on the day preceding the 3 active drug treatment days to obtain control data. Each experimental day was divided into three urine collection periods — 0 to 4 h, 4 to 12 h and 12 to 24 h. Urine output, ion excretion and clearance were measured during each of the 3 periods as well as for the 24-h period. Torasemide 20 mg was distinctly more active in each of the 3 collection periods and in the 24-h period than furosemide 40 mg, whereas no significant difference was found between furosemide 40 mg and torasemide 10 mg for most of the experimental data. From 0 to 4 h, both torasemide and furosemide significantly increased the urinary flow rate and the urinary excretion of sodium, chloride and calcium, while they decreased the urinary osmolality when compared to placebo. All the effects persisted in the 4 to 12 h period after torasemide 20 mg in contrast to furosemide, whose effects were limited to the 0 to 4 h period. In the third period (12–24 h), the urine volume fell below the placebo value after furosemide but not torasemide, and only torasemide 20 mg was followed by a persistent decrease in the urine osmolality. Both diuretics increased the free water clearance, but this phenomenon was slightly greater after torasemide. Finally, urinary potassium excretion was increased by both doses of torasemide and furosemide, with no significant difference between the three experiments. Torasemide and furosemide were well tolerated; no clinical or biochemical adverse effects occurred after administration of either of the compounds. Torasemide is a new loop diuretic which may constitute a good alternative to furosemide in the treatment of oedema in chronic heart failure.

    Notes: Summary Sixteen hospitalized insulin requiring diabetics treated with a single daily subcutaneous injection were randomly allocated either to a mixture of porcine Actrapid+Lente MC or a mixture of Regular+NPH—Biosynthetic human insulin (Study 1). In Study 2, 10 patients receiving two daily insulin injections were treated at random with either porcine Actrapid+Monotard, or Actrapid+Monotard—Semisynthetic human insulin or Regular+NPH—Biosynthetic human insulin. Once an optimal insulin regimen was obtained, circadian blood glucose and plasma free insulin profiles (7–9 time points) were determined with the two (Study 1) or three (Study 2) insulin preparations, keeping the doses of insulin constant. In Study 1 no significant difference in blood glucose (BG) or plasma free insulin (FIRI) profiles was observed. The mean daily blood glucose, the mean amplitude of glycaemic excursions (MAGE), the index of blood glucose control (M-value of Schlichtkrull), as well as the post-breakfast increases in blood glucose and mean free IRI, were similar with both types of insulin. In Study 2, BG and FIRI profiles were also similar, except for a significantly lower (p〈0.02) BG at 8.30 p.m. with both human insulins. No significant differences were found in free IRI at that time. Mean BG, M index, MAGE and mean FIRI were similar but the postbreakfast increase was significantly smaller with SHI. In conclusion, the pharmacokinetics of animal monocomponent, semisynthetic and biosynthetic human insulin appear similar, but evening BG control was better with both types of human insulins given twice daily.

    Notes: Abstract Objective: We report preliminary results from use of a radioreceptor assay (RRA) to measure serum haloperidol levels and their relation to clinical response and adverse effects in 19 psychotic patients with positive symptoms treated with haloperidol. Methods: Blood samples were taken on Days 7, 14 and 21. Clinical evaluation was based on the PANSS, and UKU scales. The D2 antidopaminergic RRA was used to measure haloperidol serum levels. Results: Our results show a correlation between psychosis with positive symptoms assessed by positive scores in the PANSS and the serum drug level measured by RRA concentrations. The observed relationship made it possible to establish a therapeutic serum range of haloperidol equivalents 15–30 ng/ml−1. This range contained no “non-responders”. Analysis of the correlation between each item on the positive subscale of the PANSS and the RRA concentration suggested that there was no specific symptom of psychosis closely related to RRA concentration during the first 15 days of treatment. In the third week, however, certain specific symptoms were closely connected to the RRA concentration. Conclusion: From these results, it can be concluded that antipsychotic activity can be related to blockade of serum D2 dopamine receptors. In future would be desirable to monitor neuroleptic treatment in this way. The study also showed that the antipsychotic treatment did not correct any specific component of the psychosis during the first stage of the treatment but that it did so at later times.

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary A single dose of glibenclamide 5 mg was administered to six Type 2 diabetics, randomly treated for 7 days either with acarbose (3×100 mg daily) or with placebo. The serum concentration of the drug was measured for 10 h. Peak concentrations, times-to-peak concentration, elimination half-lives and the extent of bioavailability of the drug were not significantly modified by acarbose. The combined administration of glibenclamide and acarbose resulted in a modest improvement in the blood glucose profile after breakfast and lunch, together with a significant diminution in plasma insulin. Thus, acarbose appears a useful additional treatment for Type 2 diabetics already receiving sulphonylurea derivatives.

    Notes: This paper presents a strain monitoring approach for following up FRP elements (in thiscase a [90°] CFRP laminate) using an embedded fibre optic sensor. The sensor exists of two fibreBragg gratings (FBGs) written in a polarization maintaining fibre (PMF). First, the strain responseof the non-embedded sensor is determined which makes it possible to relate the different bragg peakshifts with the induced strain field in the core of the optical fibre. Secondly, a transfer coefficientmatrix is presented and calculated using finite element simulations which relates the measuredstrain field of the sensor with the adjacent one existing in the structure as if no sensor would bepresent

    Notes: This paper presents the experimental study of fibre Bragg grating sensors for measuringstrain inside composite laminates during fatigue loading. The optical fibres are imbedded insidethermoplastic CFRP test-coupons which have an ultimate strain of about 1.1%. Tension – tensionfatigue cycling at a rate of 5Hz is been carried out at 314MPa with a maximum strain of 0.51%. Atsuch extreme strain levels the use of high strength sensors becomes inevitable. Neither the sensornor the composite test-coupons showed any significant degradation even after more than 500000cycles. Fibre optic Bragg grating sensors are known to be very accurate strain sensors but oneshould be very careful interpreting their response once they are imbedded inside compositematerials. In this study high strength fibre Bragg grating sensors with coating are imbedded incomposite test coupons and a pretty good correlation was found between the strain measurements ofan electrical extensometer and the imbedded sensor during the complete cycling. The high strengthsensor show to be very feasible for extreme and long term strain measurements
