    Description / Table of Contents: Abstract Although still rare, pregnancy and delivery in women with spinal cord injuries is becoming more frequent (Table 2). In 85%–90% of patients with lesions above T6 symptoms of autonomic hyperreflexia (Table 1), especially paroxysmal and excessive increases in arterial blood pressure, may occur. In anaesthesising a 31-year-old paraplegic primigravida with a complete transverse spinal lesion at T4 for an elective caesarean section, no indication of hypertonic cardiovascular dysregulation either intra- or postoperatively was observed after repeated epidural administration of bupivacaine. Distinct intraoperative spasticity of the abdominal wall muscles was, however, not influenced by the dosages selected.
    Notes: Zusammenfassung Es wird berichtet über das geburtshilflich-anästhesiologische Vorgehen und den peripartalen Verlauf bei einer 31jährigen Erstgravida mit traumatischer Querschnittsläsion in Höhe Th 4 und klinischen Zeichen einer autonomen Hyperreflexie (AH). In der 37. Schwangerschaftswoche erfolgte eine primäre Sectio caesarea aus kindlicher Indikation. Hypertone Kreislaufdysregulationen im Rahmen von AH-Attacken wurden unter repetitiver Bupivacainanwendung über einen Periduralkatheter nicht beobachtet, eine ausgeprägte intraoperative Spastik der Bauchdeckenmuskulatur war mit den gewählten Dosen allerdings nicht zu beeinflussen.

    Notes: The pineal gland of the 13-lined ground squirrel (Citellus tridecemlineatus) has been examined at the light and electron microscopic level. This gland is composed of low-density parenchymal cells interspersed among which are occasional glial, vascular and neural elements. Punctuating the glandular parenchymal mass are prominent perivascular and intercellular spaces.The parenchymal cells possess numerous mitochondria and less prominent profiles of rough and smooth-surfaced endoplasmic reticulum. Golgi apparatus, microtubules and lipid droplets of varying size and electron density constitute regular cytoplasmic features, with dense-core vesicles being present occasionally. The parenchymal cells have numerous processes. One among these in each cell extends for several micra to terminate in a bulbous expansion containing both clear and dense-core vesicles and occasional electron-dense inclusions. These bulbous terminals are found within the perivascular and intercellular spaces where they course in close proximity to both other parenchymal elements and axon terminals. Glial cells and their processes invest the pineal periphery and incompletely separate the parenchymal cells.

    Notes: Orthotopic cardiac allotransplantation was performed on ten adult mongrel dogs. At the time of acute rejection (decline in QRS voltage to at least onehalf of the post-operative level) a cardiac biopsy was removed from the left ventricle of each dog and followed by 300 r of local x-irradiation on five consecutive days. After a full course of x-irradiation (1500r) to each dog a second biopsy was removed from the left ventricle. In this way, each dog acted as its own control in order to determine the effects of x-irradiation on cardiac transplants and the rejection phenomenon. The electron microscopic findings at the time of acute rejection involved primarily the myocytes and their cellular organelles in that the A, I, and Z bands were less distinct and there was significant enlargement and cytological distortion of the mitochondria, endoplasmic reticulum and T tubules. Endothelial hyperplasia of the smaller blood vessels was also more apparent in the pre-irradiation biopsies. Following irradiation the ultrastructural changes appeared to be reversed in six of the ten dogs; mitochondria and other organelles of the myocytes were more normal and the banding of the fibers was more distinct. Vascular alterations were less and the tissue approached normal cytological architecture. Pre- and post-irradiated cardiac tissues were not different in two animals and in two other animals the post-irradiated tissues appeared more abnormal than those showing acute rejection. Local irradiation as a method of immunosuppression in cardiac transplants is discussed.
