    Notes: The obstetrical outcome of pregnancy in primigravid patients aged 16 years or less of three racial groups, white, Cape coloured and Bantu, is compared. Each group consisted of 100 consecutive patients.The major differences found were an increased incidence of cephalo-pelvie disproportion and associated high Caesarean section rate in the Cape coloured and Bantu groups, a lower rate of engagement of the fetal head before labour in the non-white patients and a high prematurity rate in the Cape coloured group.An equally high incidence of toxaemia of pregnancy was found in all racial groups and the increased incidence of this syndrome in the young primigravid patient was confirmed.

    On the Role of Calcium Ions in the Regulation of Glycogenolysis in Mouse Brain Cortical Slices (1982)

    Notes: Abstract: Using mouse brain cortical slices, we investigated the relative roles of cyclic AMP and of calcium ions as the intracellular messengers for the activation of glycogen phosphorylase (EC 2.4.1.1; α-1,4-glucan:orthophosphate glucosyltransferase) induced by noradrenaline and by depolarization. Activation of phosphorylase by 100 μM noradrenaline is mediated by β-adrenergic receptors and does not require the copresence of adenosine. The role of the concomitant small increase in cyclic AMP is questioned. Short-term treatment with EGTA or LaCl3 abolishes the noradrenaline activation of phosphorylase, pointing to a critical role of extracellular calcium. Depolarization by 25 mM K+ or 100 μM veratridine produces a rapid and large (fourfold) activation of phosphorylase. Only veratridine increases the cyclic AMP levels; exogenous adenosine deaminase essentially blocks this cyclic AMP accumulation but not the phosphorylase activation. A halfmaximal activation of phosphorylase occurs at about 12 mM K+. Addition of EGTA or LaCl3, reduces the effect of both depolarizations to a slight and transient activation of phosphorylase. These results indicate that activation of glycogen phosphorylase by K+ or veratridine occurs by a cyclic AMP-independent and calcium-dependent mechanism. The calcium dependency of brain phosphorylase kinase renders this kinase the prime target enzyme for regulation of glycogenolysis by calcium ions.

    Description / Table of Contents: Zusammenfassung Es wurden die Sektionsprotokolle von 939 Unfalltoten ausgewertet und mit den klinischen Unterlagen der Patienten verglichen, welche in klinische Behandlung kamen. Der Kliniker wird mit den Verletzungen der inneren Organe des Brust- und Bauchraumes seltener konfrontiert als der Pathologe. Bei der klinischen Diagnostik werden am häufigsten übersehen die Rippenserienfraktur und Wirbelfraktur, das intrakranielle Hämatom und eine Verletzung der parenchymatösen Bauchorgane.
    Notes: Summary The autopsy reports of 939 accidental deaths were evaluated and compared with the clinical data of those of the patients who had received clinical therapy. Intrathroacic and intra-abdominal injuries are seen less often by the clinician then by the pathologist. The lesions most frequently overlooked in clinical diagnosis are fractures of the ribs and of the vertebral spine, intracranial haematomas, and injuries of intra-abdominal parenchymatous organs.

    Localization of radioactivity in rat organs after oral administration of tritiated 8-methoxypsoralen in therapeutic doses (1982)

    Notes: Summary Tritiated 8-methoxypsoralen was given perorally to rats in amounts corresponding to therapeutic human doses. The rats were exposed to UVA light or kept in darkness. None of the fractions (apart from 3H2O from the lens) examined changed their level of radioactivity under the influence of UVA light. Time-radioactivity curves were recorded for the skin, lens, residual eye, and the liver. Four fractions were measured: 3H2O, soluble pool, DNA-RNA, and protein. Tritiated water appeared already 1 h after ingestion, and attained maximum value 9–24 h after ingestion, indicating the efficiency with which the liver degrades 8-MOP. 3H-8-MOP and metabolites could be detected in the soluble pool in maximum amounts 2–3 h after the administration. Pretreatment with trypsin increased the concentration of 3H-8-MOP and metabolites; the origin of this extra radioactivity was the protein fraction. The 3H-8-MOP binding to DNA or RNA was studied by pretreatments of the homogenates with DNase or RNase followed by measurement of radioactivity in the TCA extracts. This indicated that no measurable amount of 3H-8-MOP had been bound to DNA or RNA. We conclude that 8-MOP administered to rats in amounts corresponding to human therapeutic doses does not bind to DNA or RNA in measurable amounts either after UV-light or in darkness. The experiments have shown proteins to be the main binding site in rat organs.

    Notes: Abstract The establishment of an in vitro fertilization program is described. Organization of the physical laboratory, media formulation, and preliminary mouse embryo culture are discussed. Parameters of patient eligibility, ovarian stimulation, and laporoscopy are also defined. At the conclusion of Phase I, 17 patients were induced; 10 went to laparoscopy, and at least one four-cell embryo was returned to 7, resulting in one continuing pregnancy.
