    Description / Table of Contents: Résumé Dans le cadre d'une étude micro-anatomique de l'angle ponto-cérébelleux, la vascularisation de 50 nerfs faciaux est examinée sous microscope opératoire après injection au latex coloré ou à l'encre de Chine. Cette étude permet aux auteurs de décrire un double apport artériel: l'un proximal, né au niveau du tronc cérébral, résulte de la confluence de 3 à 5 artérioles issues de l'ACiA ou de l'artère basilaire ellemême; l'autre distal, au niveau du méat acoustique interne, provient de l'artère labyrinthique. Ces deux systèmes artériels ne s'anastomosent pas entre eux à plein canal, mais par des capillaires d'un diamètre inférieur à 200 microns. Les auteurs en tirent argument pour estimer que certaines paralysies faciales post-opératoires survenant malgré la conservation anatomique du nerf, sont de nature ischémique.
    Notes: Summary The blood supply of 50 facial nerves was examined during a micro-anatomical study of the ponto-cerebellar angle using injections of colored latex or Chinese ink. The results indicate the presence of a double arterial blood supply: the proximal supply, rising at the level of the brain stem, results from the confluence of three to five arterioles originating from the anterior inferior cerebellar artery or from the basilar artery itself; the distal supply at the level of the internal acoustic meatus arises from the labyrinthine artery. These two arterial systems do not anastomose directly but by way of capillaries of less than 200 microns in diameter. From these findings the authors conclude that certain postoperative facial paralyses, which may arise in spite of the conservation of the nerve, are in fact ischemic in nature.

    Notes: Summary To determine if cGMP might function as a second messenger for insulin, anin situ liver perfusion system was established in which hepatic effects of insulin could be correlated with changes in cyclic nucleotides. Several combinations of insulin (10 mU/ml) and glucose (50 mg/ml) were infused (0.1 ml/min) for 30 min into fasted normal and diabetic rats with removal of a similar volume of blood. Samples of livers were removed at the beginning and end and at various times during the perfusion. In normal animals perfused with buffer alone, hepatic glycogen content fell. When glucose (with or without added insulin) was added to the perfusate, glycogen levels rose. With buffer alone, there was no change in the independent (I) form of glycogen synthase at 10 min but a modest increase at 30 min. With insulin and/or glucose, there was a large increase in the I-form of the enzyme at 10 min and a further rise at 30 min. Neither cGMP nor cAMP changed even though tissue samples were obtained at multiple times throughout the perfusion. Cyclic nucleotides were also measured in liver slices exposed to insulin (1 mU/ml) after 30 min of preincubation for stabilization. Although significant increases in cGMP were noted in the tissue exposed to insulin, similar significant rises also occurred in appropriately paired control slices. When glucagon was used in both thein situ perfusion and the paired liver slice systems, the expected rapid and large increases in cAMP levels occurred attesting to the validity of both approaches in evaluating hepatic cyclic nucleotide responses. These results plus the paucity of convincing data in the literature strongly suggest that cGMP can no longer be considered a candidate for the putative second messenger of insulin.

    Notes: Conclusion Our ongoing study shows that HSF cultures can be used as an in vitro model for AA metabolism studies. The incubation medium however has to be standardised in order to obtain comparable results. The addition of albumin to the medium is necessary for dissolution of different agents like ionophore, indomethacin or others and does not change the AA metabolism. Differences between different cell lines of healthy donors are under investigation but seem to be of minor importance when the skin biopsie is taken from the same place, whereas greater differences were observed between HSF cultured from arm or foreskin biopsies. Finally it could be proved that the cyclooxygenase pathway is more important than that of the lipoxygenase and that 11-HETE derives from the cyclooxygenase and not from the lipoxygenase activity. The main lipoxygenase product is 15-HETE.
