    Description / Table of Contents: Summary The case has been presented of a Japanese aged 22 who was suffering from hereditary non-spherocytic haemolytic anaemia. This was a constant type of anaemia associated with reticulocytosis, jaundice, and glucose-6-phosphate dehydrogenase deficiency of the erythrocytes. Although it was not possible, owing to the absence of enzymic activity, to estimate isoenzyme in the patient's erythrocytes, the isoenzyme was assigned, in the patient's mother and in other members of his family, as well as in controls, to the B type. Cytochemical investigations revealed the presence of a cellular mosaic in the patient's mother who was heterozygous, but in the patient, as well, who himself was hemizygous.
    Notes: Zusammenfassung Es wird über einen 22jährigen Japaner mit einer hereditären, nichtsphärozytären hämolytischen Anämie berichtet. Es bestand eine konstante Anämie mit Retikulozytose, Ikterus und Mangel an Glucose-6-Phosphat-Dehydrogenase in den Erythrozyten. Obwohl der Nachweis von Isoenzym an den Erythrozyten des Patienten wegen fehlender Fermentaktivität nicht gelang, konnte es bei der Mutter, bei den übrigen Familienangehörigen und bei Kontrollfällen dem Typ B zugeordnet werden. Cytochemische Untersuchungen ergaben das Vorliegen eines Zellmosaiks in der heterozygoten Mutter des Patienten, jedoch auch im hemizygoten Patienten selber.

    Notes: Abstract. We report an uncommon case of spontaneous massive hemorrhage of the abdominal wall caused by rupture of a deep iliac circumflex (DIC) artery. Enhanced computed tomography (CT) demonstrated a marked extravasation in a huge hematoma of the abdominal wall. Although a pelvic arteriogram demonstrated no extravasation, a superselective DIC arteriogram subsequently revealed an extravasation of the artery. We successfully performed transcatheter arterial embolization for the artery. There have been few reports in the literature of spontaneous hemorrhage in the abdominal wall resulting from rupture of DIC artery, which were defined by diagnostic imaging and successfully treated by transcatheter arterial embolization.

    Notes: Abstract The effect of the new substituted benzimidazole proton pump inhibitor, lansoprazole, on pharmacokinetics and metabolism of theophylline has been studied in healthy adults given oral lansoprazole 30 mg once daily for 11 days. On Days 4 and 11 of 300 mg aminophylline was simultaneously administered orally and blood samples for theophylline analysis were taken over 24 h. Urine samples were collected for up to 24 h and were assayed for theophylline and its major metabolites 1,3-dimethyluric acid (1,3-DMU), 1-methyluric acid (1-MU) and 3-methylxanthine (3-MX). The pharmacokinetic parameters of theophylline were determined, and the urinary recovery of unchanged theophylline and its major metabolites were calculated. After administration of lansoprazole for 4 days, no significant alteration in the terminal elimination half-life (t 1/2β) or the mean residence time (MRT) was detected. However, there was a significant decrease of about 13% in the area under the plasma concentration-time curve (AUC) and a significant increase of about 19% in the apparent clearance (CLapp). Lansoprazole treatment for 11 days caused a significant decrease of approximately 12% in t 1/2β and about 10% in the MRT of theophylline, although neither AUC nor CLapp showed a significant alteration. The excretion of 3-MX in the urine was significantly increased by about 20% after lansoprazole treatment for 4 and 11 days, although there was no significant alteration in the excretion of unchanged theophylline, 1,3-DMU or 1-MU. The results indicate that repeated administration of lansoprazole to humans induces the hepatic microsomal P-450-dependent drug oxidation system that mediates N-1-demethylation of theophylline, consequently increasing its metabolism.

    Notes: Summary Ventricular cerebrospinal fluid (CSF) lactate concentrations and lactate/pyruvate (L/P) ratios were measured daily in 20 patients from day 1 to day 12 after subarachnoid haemorrhage due to ruptured aneurysms. Patients without symptomatic vasospasm were classified in Group 1, patients with symptomatic vasospasm were classified in Group 2, and patients who were Hunt and Kosnik grade 4 on admission clinically were classified in Group 3. Patients in all three groups had high CSF lactate concentrations on day 1, and, especially in Group 3, the high lactate was accompanied by an increased L/P ratio and a decreased CSF bicarbonate. Lactate concentrations in Group 1 decreased throughout the observation period. Lactate concentrations in Group 2 also decreased but then began to increase again on days 5 to 7, correlating well with the onset of cerebral vasospasm. The delayed increase of CSF lactate in Group 2 was also accompanied by increases in the CSF pyruvate level and the CSF L/P ratio. Daily monitoring of CSF lactate may thus serve as a chemical marker for cerebral vasospasm.

    Notes: Morphology and coefficient of friction associated with water content in the skin were investigated by a combination method of profilometry and measurement of friction using a newly developed instrument placed on the flexor aspect of the forearm. It was shown that the number of domains enclosed by lines (sulci cutis) on the skin surface per unit area initially decreased rapidly, but then more gradually, with the advancing age of the subjects. Electron micrographs showed that the skin surface exhibited a pattern formed by thick and fine lines, each of which differed both in length and depth from the superficial surface of the skin. The pattern of the skin surface in advanced age is mainly formed by thick lines. The number of domains on the skin surface caused changes in the friction coefficient; that is, the increase in the static coefficient of friction varies with the decrease in the number of domains. The results are discussed from the point of view of the change in the elastic modulus of skin with the advancing age of subjects. We found that the number of domains (i.e., areas enclosed by lines) varied inversely with the square of the coefficient of friction.〈section xml:id="abs1-2"〉〈title type="main"〉RésuméLe coefficient de morphologie et de friction associé avec le contenu en eau de la peau a été analysé en combinant 1 méthode de profilométrie et la mesure de la friction à l'aide d'un nouvel instrument placé sur la partie flexible de l'avant bras. Il est apparu que le nombre de sillons par ligne (sulci cutis) sur la surface cutanée par unité d'aire à d'abord diminué rapidement puis graduellement avec le vieillissement des individus. Les micrographes à électrons ont montré que la peau était formée de ligne fines ou épaisses, chacune d'entre elles différent par la longueur et la profondeur sur la surface de la peau. La surface cutanée de personnes plus âgées est formée principalement de lignes épaisses. Le nombre de sillons sur la peau modifiait le coefficient de friction, le coefficient de friction statique correspondant à la diminution du nombre de sillons. Les résultats ont été discutés du point de vue du changement d'élasticité de la peau avec le vieillissement des sujets. Nous avons découvert que le nombre de sillons c'est à dire les aires par ligne variait inversément par rapport au coefficient de friction.
