    Notes: Increasing numbers of patients with spinal cord injury present for surgery or obstetric care. Spinal cord injury causes unique pathophysiological changes. The most important peri-operative dangers are autonomic dysreflexia, bradycardia, hypotension, respiratory inadequacy and muscle spasms. Autonomic dysreflexia is suggested by headache, sweating, bradycardia and severe hypertension and may be precipitated by surgery, especially bladder distension. Patients with low, complete lesions, undergoing surgery below the level of injury, may safely do so without anaesthesia provided there is no history of autonomic dysreflexia or troublesome spasms. An anaesthetist should be present to monitor the patient in this situation. General anaesthesia of sufficient depth is effective at controlling spasms and autonomic dysreflexia but hypotension and respiratory dysfunction are risks. There is a growing consensus that spinal anaesthesia is safe, effective and technically simple to perform in this group of patients. We present a survey of 515 consecutive anaesthetics in cord-injured patients and a review of the current literature on anaesthesia for patients with chronic spinal cord lesions.

    Description / Table of Contents: Résumé Complétant un travail antérieur de l'anatomie macroscopique et histologique de la veine ombilicale de l'adulte, une étude histologique et radiologique a été faite sur des cadavres afin de déterminer le trajet suivi par des sondes ou des cathéters introduits dans cette veine afin d'obtenir un accès sur le système porte. Bien qu'il persiste une partie de la lumière initiale, son diamètre est trop étroit (approximativement 0,2 mm) pour admettre des sondes et des cathéters. Les instruments se fraient un passage artificiellement à travers une zone interne lâche qui est la ≪lumière apparente≫ de la veine. Cette zone centrale qui est formée après la naissance est plus pâle et de consistance moins ferme que les zones périphériques mais elle devient plus fibreuse avec les années et sa reperméabilisation est alors plus difficile. A la jonction veine ombilicale-veine porte, la sonde est arrêtée par la paroi de la branche gauche de la veine porte qui se divise à ce niveau (récessus ombilical). Une perforation de cette paroi par pression de la sonde permet de pènètrer dans le système porte. Sans une reperméabilisation préalable, l'injection de liquide de contraste dans la lumière apparente de la veine ombilicale ne pénètre pas dans le système porte.
    Notes: Summary Following a previous study of the gross anatomical and histological features of the adult umbilical vein, a histological and radiological investigation has been made on post-mortem material, to determine the route taken by probes and catheters introduced into the hemisected vein, to obtain access to the portal system. Although a residual part of the original lumen persists, it is far too small in diameter (approximately 0.2 mm) to admit probes and catheters. The instruments traverse a loose inner zone (the ‘apparent lumen’) and form a false passage within it. This zone, which is formed postnatally, is paler and of softer consitency than the surrounding zones, but since it becomes more fibrous and contracted in later life, instrumentation could prove more difficult in the elderly. At the umbilical-portal junction, the probe is arrested by the diverging right wall of the terminal expansion of the left branch of the portal vein (the recessus umbilicalis). Local rupture of the inner part of the wall by probe pressure gives access to the portal system. Without prior probing, contrast medium injected locally into the apparent lumen does not reach the portal system.

    Notes: Summary Concentrations of transcortin binding sites and apparent dissociation constants for corticosterone have been measured in the blood of control and thyroidectomized chick embryos. The levels of corticosterone binding are quantitatively similar in normal and thyroidectomized embryos and vary in parallel during development.

    Notes: Abstract The cellular origin and kinetics of TXB2 and 6-keto PGF1α in carrageenan-induced pleurisy has been studied. Maximum levels of these prostanoids occurred 1 hour after induction of pleurisy. Mononuclear cells initially present in the pleural cavity synthesized TXB2 and 6-keto PGF1α from (14C) arachidonic acid. By contrast, PMN cells harvested 6 hours after the induction of inflammation did not produce 6-keto-PGF1α. Selective inhibition of thromboxane synthetase with drugsin vitro andin vivo increased the formation of 6-keto-PGF1α, the stable breakdown product of PGI2. This metabolic effect was parallel to an increase in the volume of exudate and in PMN migration. These results suggest that TXA2 seems to be implicated not only as a chemotactic agent but also as an antagonist of PGI2 vasodilator effects.

    Notes: Abstract Complex I, a key component of the mitochondrial electron transport system, is thought to have evolved from at least two separate enzyme systems prior to the evolution of mitochondria from a bacterial endosymbiont, but the genes for one of the enzyme systems are thought to have subsequently been transferred to the nuclear DNA. We demonstrated that the cellular slime mold Dictyostelium discoideum retains the ancestral characteristic of having mitochondria encoding at least one gene (80-kDa subunit) that is nuclear encoded in other eukaryotes. This is consistent with the cellular slime molds of the family Dictyosteliaceae having diverged from other eukaryotes at an early stage prior to the loss of the mitochondrial gene in the lineage giving rise to plants and animals. The D. discoideum mitochondrially encoded 80-kDa subunit of complex I exhibits a twofold-higher mutation rate compared with the homologous chromosomal gene in other eukaryotes, making it the most divergent eukaryotic form of this protein.

    Description / Table of Contents: Fragestellung: Die ständig wachsenden Erkenntnisse über die molekularen Ursachen vieler Augenkrankheiten eröffnen auch neue Therapiemöglichkeiten. Wie kann die fortschreitende Genotyp-Phänotyp-Korrelation für die Entwicklung einer Gentherapie genutzt werden? Material und Methoden: Der Gentransfer kann bei rezessiven Erkrankungen für den Genersatz, bei dominanten Erkrankungen für die gezielte Inaktivierung, bei degenerativen Erkrankungen für die Expression von sogenannten „rescue factors“ oder zur Apoptosismodulation, bei proliferativen Erkrankungen für die Expression von „suicide genes“ und bei immunologischen Erkrankungen zur Immunmodulation genutzt werden. Allen Strategien ist die Übertragung von Fremd-DNA in ein Zielgewebe des Auges durch ein Vektorsystem gemeinsam. Ergebnisse: Vor allem virale Vektorsysteme sind bereits für den Gentransfer am Auge untersucht worden: Adenovirus (AV), Adeno-assoziiertes Virus (AAV), Encapsidated adenovirus minichromosomes (EAMs), Herpes-simplex-Virus (HSV) und Lentiviren. Für den Gentransfer in die Netzhaut hat AAV zur Zeit das größte Potential. Die Transduktionseffizienz der Vektorsysteme, ihre Vor- und Nachteile, die verwendeten Tiermodelle und der Stand der Forschung werden diskutiert. Schlußfolgerung: Der Gentransfer ist auch in der Augenheilkunde ein vielversprechender aber immer noch experimenteller Therapieansatz.
    Notes: Background: Research into the molecular and genetic basis of disease is continually expanding. How does the increasing knowledge about the genetic basis of eye diseases contribute to the development of new therapeutic strategies? Materials and methods: Gene therapy, here defined as the introduction of genetic material into human cells, offers great opportunities. Gene transfer strategies can be used for gene replacement in recessive disease, gene inactivation in dominant disease, expression of “rescue factors” and apoptosis modulators in degenerative disease, “suicide genes” for example in proliferative diseases and expression of immunmodulatory factors in immunological disorders. Viral vector systems have been developed to introduce the gene of interest into the target cell. Results: Most of the published strategies include the use of vectors for gene transfer. Adenovirus (AV), adenoassociated virus (AAV), encapsulated adenovirus mini-chromosomes (EAMs), herpes simplex virus (HSV) and lentiviruses are the most frequently used viral vector systems to date. Their advantages and disadvantages, the in vivo models used for gene transfer in retinal degeneration, and the results obtained to date by different research groups in the field will be reviewed. Conclusions: Gene transfer into ocular tissues has been demonstrated with growing functional success and may develop into a new therapeutic tool for clinical ophthalmology.
