    Notes: Summary The generation of osteoclasts in cultures of cat bone marrow was completely inhibited for 4 weeks with 10−6M hydrocortisone (HC) and partially inhibited with 10−7 to 10−9M in a dose-dependent fashion. This effect was completely reversible when cultures were exposed for only 2 weeks to 10−9 or 10−8M HC. However, cultures in which higher concentrations (10−7 to 10−5M) were maintained for the same period did not show complete recovery in terms of numbers of osteoclasts and number of nuclei per cell after withdrawal of HC, suggesting that precursor cells of osteoclasts were also damaged by HC. To study the effects of HC on osteoclasts already present in the cultures, 10−6M was added to 4-week-old untreated cultures. The number of osteoclasts decreased rapidly and a gross morphological response was also apparent (rounding of the cells leading to detachment from the substratum and inhibition of cell fusion), indicating that the generation as well as the survival of osteoclasts in vitro are sensitive to HC. The morphological changes observed under optical and electron microscopy correspond to those of the reported inactive form of osteoclasts, and suggest that their function may also be altered by HC.

    Notes: Abstract: A sensitive radioisotopic assay has been used to examine the kinetic properties and regulation of biosynthesis of glutamine synthetase in C-6 glioma cultures. The Km values for glutamate, MgATP, and ammonium ion were 5mM, 14 mM, and 0.042 mM, respectively, when measured at the pH optimum of 7.2. There was an absolute requirement for a divalent metal ion, with 15 mM- Mg2+ being the preferred ion at pH 7.2. Activity was completely inhibited after 30 min with 8 mM-L-methionhe sulfoximine. The addition of 1 μM-cortisol to C-6 cultures caused a two to threefold increase in glutamine synthetase specific activity over a 96-h period, while dexamethasone at the same concentration elevated the level some 7-10-fold. This was specific for glucocorticoids, as other steroid hormones or catecholamines did not significantly affect glutamine synthetase specific activity. Cycloheximide (30 μM) or actinomycin D (0.01 μg/ml) blocked the hormone response. The continued presence of hormone was required in order to maintain an elevated enzyme level. The results suggest that glucocorticoids act to induce glutamine synthetase by stimulating new enzyme synthesis.

    Description / Table of Contents: Résumé Les auteurs décrivent une méthode d'évaluation globale du pied, tant avant qu'après correction chirurgicale, chez des adolescents porteurs d'hallux valgus. Elle nécessite une série d'études des caractéristiques cliniques, photographiques et radiologiques, ainsi qu'une évaluation dynamique de la marche à l'aide d'un plateau de force. Cette méthode a été utilisée pour estimer avec exactitude les modifications survenues sur 36 pieds après que l'hallux valgus ait été traité par une variante de l'ostéotomie oblique du premier métatarsien décrite par Wilson, qui consiste en une résection d'un coin osseux suivie de fixation par une vis. Durant les six premiers mois post-opératoires, on note un déplacement de l'appui de l'avant-pied vers le dehors et une diminution de la charge au niveau des orteils, mais il y a une tendance à revenir à la répartition pré-opératoire de l'appui au cours des quatre années suivantes. La persistance du déplacement externe de l'appui semble résulter de la surélevation de la tête du premier métatarsien, conséquence du raccourcissement de cet os créé par l'ostéotomie. Ceci peut être évité en abaissant délibérément la première tête métatarsienne lors de l'opération et en fixant les fragments par une vis dans la position désirée.
    Notes: Summary A comprehensive method of evaluating the feet of patients with adolescent hallux valgus both before and after surgical correction is described. Serial clinical, photographic and radiological studies were made and a dynamic assessment of gait was carried out using a load-sensitive walkway. Observations were made on 36 feet in which hallux valgus was treated by a modification of the Wilson oblique metatarsal osteotomy, with removal of a wedge of bone and screw fixation. In the first six months after operation, there was a lateral shift of the weight-bearing pattern in the forefoot and less weight was taken on the toes, but there was a tendency to return to the pre-operative distribution of weight during the next four years. Persistence of the lateral shift of weight-bearing appeared to result from elevation of the first metatarsal head secondary to shortening of the first metatarsal during the osteotomy. This can be avoided by deliberate depression of the first metatarsal head at the time of operation and fixation of the fragments in the required position with a screw.

    Notes: Abstract In a previous article describing the anteroposterior angled caudad view the authors described a technique to more clearly evaluate the posterior elements of the lumbosacral spine, especially the articular facets, using standard radiographic techniques. This article details the specific pathology which can be evaluated. Multiple cases and examples of the view are given and comments regarding calcifications of the capsule of the articular facets and findings in trauma and post-surgical changes are described.

    Notes: Abstract Liposomes containing cortisol palmitate showed greater anti-inflammatory activity than water soluble cortisol succinate, following intravenous injection into rats, as sssessed by inhibition of (a) carrageenan-induced paw swelling, and (b) inflammatory responses in subcutaneous sponge implants impregnated with heat-killedMycobacterium tuberculosis.

    Notes: Abstract Brief and impulsive signals of uncertain origin appear regularly on records from Ocean Bottom Seismographs (OBS) of several institutions. These signals have been recorded on nearly all deployments of the Texas OBS, including sites at depths greater than 7000 m. At some sites, they account for over 90% of the events recorded. They are of short duration (usually 0.5–4.0 s) and have a characteristic frequency (usually in the range of 4–18 Hz) that differs from site to site. When networks of OBS instruments are deployed, the signals are not recorded simultaneously by different instruments. Neither the frequency content nor the distribution of durations of these signals is similar to what is observed for known earthquake events. We present evidence suggesting that the signals are of biological origin, perhaps caused by animals touching the OBS units. (1) The distribution of these signals on instruments deployed at depths shallower than 1000 m shows a 24 h periodicity, while there is a 24 h periodic pattern on instruments deployed at sites deeper than 1000 m (where there is no visible light). (2) The frequency of occurrence of signals is similar to the vertical distribution of biomass in the oceans, i.e., they appear most frequently on OBS instruments deployed at very shallow depths. (3) Biological material has been found attached to several OBS units upon recovery.
