    Notizen: Abstract To make a digital image database of human craniology, we optimized the three-dimensional (3-D) images of 29 dried human skull specimens by helical computed tomography (CT). For the verification of the quantitative exactitude of these image data, we manually measured nine items of direct distances between standard anthropologic points on each skull and the corresponding distances projected on the CT monitor by specifying the respective points. The results obtained by the two methods of manual and CT measurements were compared and statistically analyzed. The CT measurements were so exact that the lower limit of correlation coefficients (95% of the confidence interval) between the two results was more than 0.8 in six items; i.e., maximal cranial length and breadth, minimal frontal breadth, bizygomatic breadth, distance between ectomolares and nasion-basion length. In contrast, the CT results were less well correlated with the manual measurements of three items; i.e., distance between bilateral mastoidales, total facial height, and nasal breadth. We concluded that the qualitative representation of 3-D CT images was adequate, although some quantitative data may be incorrect. The inaccuracy is suspected to be due to the difficulty in specifying the standard points on the CT images, and due to the differences in measurement procedures between the direct and projected distances.

    Notizen: Summary Glycolipid transfer protein (GL-TP), a nonglycosylated protein with a molecular weight of 22,000 K, has been purified from pig brain. The protein transfers, by a carrier mechanism, glycolipids with a β-glucosyl or β-galactosyl residue directly linked to either ceramide or diacylglycerol. GL-TP appears to be present in most animal cells, and evidence has been obtained which indicates that it is a cytoplasmic protein. Little is known about the function of GL-TP. Current evidence indicates that glycosphingolipid glycosylation occurs at the luminal side of the Golgi apparatus, except for the glucosylation of ceramide, which has been shown to occur at the cytoplasmic side of the Golgi or endoplasmic membrane. It appears most likely that GL-TP participates in the intracellular traffic of glucosylceramide.

    Beschreibung / Inhaltsverzeichnis: Résumé Afin d'établir une banque informatisée de données en crâniologie humaine, nous avons recueilli les images tridimensionnelles, de 29 crânes secs, obtenues par scanner hélicoïdal. Pour vérifier les données obtenues, nous avons mesuré manuellement 9 longueurs situées entre les repères crâniologiques classiques sur chaque crâne et les distances correspondantes entre les points analogues sur la console du scanner. Les résultats obtenus par les 2 méthodes de mesure manuelle et par scanner sont comparés et analysés statistiquement. Les mesures scanner sont situées à la limite inférieure de corrélation entre les 2 résultats (95% d'intervalle de confiance) et supérieures à 0.8 dans 6 mesures : la longueur et la largeur maximales crâniennes, la largeur minimale frontale, la largeur bizygomatique, la distance entre les faces externes des molaires et la longueur nasion-basion. Par contre, les mesures scanner sont moins concordantes avec les résultats manuels dans 3 mesures : distance intermastoïdienne, hauteur faciale totale et largeur nasale. Nous en concluons que la représentation qualitative des images scanner est correcte, même si quelques données chiffrées sont imprécises. Les causes d'erreurs sont, semble t-il, dues à la difficulté de repérer les points crâniologiques précis sur les images scanner, ainsi qu'à la différence des techniques de mesure entre une donnée directe et une en projection.

    Notizen: Summary The pharmacokinetics and absolute bioavailability of a new nonselective β-adrenoreceptor blocking agent, carteolol, were investigated after administration of single intravenous and oral doses to eight normal volunteers. Plasma and urine drug concentrations were measured by an HPLC method. The pharmacokinetic parameters after intravenous dosing were obtained by a two-compartment analysis: elimination or β-phase t1/2 4.7±0.3 h; Vc, 0.74±0.101/kg; Vd, 4.05±0.48 l/kg; Cl, 10.13±0.94 ml/min/kg; ClR, 6.56±0.58 ml/min/kg; and ClNR, 3.57±0.40 ml/min/kg. The absolute bioavailability obtained from plasma data was 83.7±8.0%, which was consistent with that derived from analysis of urine of 82.7±4.2%. The amounts excreted unchanged in urine up to 48 h after the intravenous and oral doses were 65.0±1.5% and 53.8±3.2% of the administered doses, respectively. The t1/2 for removal of the drug derived from plasma and urine findings after intravenous and oral dosing were similar, which indicates that the main route of elimination of carteolol is via the kidneys. As the ClR of carteolol exceeded the Cl of creatinine there may be renal tubular secretion of the drug.

    Notizen: Summary The pharmacokinetics of ketoprofen was studied in the same healthy subjects after single oral, intramuscular and rectal doses, and after repeated oral administration. No significant difference in the mean t1/2 (1.13–1.27 h) was observed after the different modes of administration. The mean [AUC] 0 ∞ after rectal administration of a suppository showed the minimum significant difference (p〈0.05) from that after oral administration of the capsule. The apparent volume of distribution (Vd/F) was approximately 10–15% of body weight. The renal contribution (mean, 0.10–0.15 ml/min/kg) to the plasma clearance of free ketoprofen was assumed to be, at most, 8.3–12.9%. The projected cumulative excretion of total (free plus conjugated) ketoprofen via urine exceeded 63–75% of the dose, of which approximately 90% was ketoprofen glucuronide. A mean of 71–96% and 73–93% of the oral capsule was estimated to be systemically available after administration of the intramuscular preparation and rectal suppository, respectively. In four of seven subjects, CPK concentration was elevated after the intramuscular injection. The mean steady-state concentration of ketoprofen in plasma ranged from 0.43 to 5.62 µg/ml after the final dose of a 50 mg q.i.d. regimen. The disposition data and plasma levels observed at steady-state were in agreement with those predicted from the single oral dose study. The accumulation ratio was 1.08±0.08. The results suggest that the rectal suppository can be recommended as an extravascular mode of administration of this drug.
