[Q]: Abstract: In two typical cases of calcaneal fracture dislocation, the primary fracture, which runs forward and medially from a point behind the sustentaculum tali, is associated with inversion of the hindfoot. The calcaneus splits into a small anteromedial and a larger posterolateral fragment. Rupture of the lateral collateral ligament allows the posterolateral calcaneal fragment to move laterally to lie immediately subjacent to the distal fibula. Closed reduction is impossible. Open reduction of this rare fracture dislocation is essential. A lateral approach to the calcaneus is generally sufficient, but a second medial incision may be required.

[Q]: Abstract: A reverse hemolytic plaque assay for detecting casein release from individual mammary cells in culture was developed as a bioassay for PRL. Treatment with rat PRL caused dose-related increases in the percentage of mammary cells that released casein and the average size of casein plaques that formed. The assay exhibited exquisite sensitivity (156 fg rat PRL per assay slide) and could be used to evaluate the biopotency of PRL released from individual cells. By combining this "plaque bioassay" with a standard plaque assay for measuring the secretion of immunoreactive PRL, it was possible to compare the bio- and immuno-potencies of hormone released from the same pituitary cells. The results of three separate studies revealed major differences among PRL secretors in these potency estimates. Given the existence of PRL variants with different biological and immunological efficacies, these findings suggest that PRL cells differ from one another in the molecular form(s) of hormone released.

[Q]: Abstract: The role of the epithelium has been studied in the contractile responses of rat trachea. The different modulations observed are discussed in respect to vagal components of the epithelial layer. Responses of rat trachea to immunologic stimulation are shown to be dependent on the presence of the epithelium, which prolongs the relaxation stage without affecting the contractions. This prolongation is abolished by neonatal capsaicin pretreatment, whereas substance P induces a significantly greater relaxation of serotonin-precontracted intact than deepithelialized trachea. Serotonin concentration-response curves are shifted to the right in intact preparations, which is partly reversed by neonatal capsaicin pretreatment, but a hyporeactivity of the tissue exists. A relaxing factor released by the epithelium is hypothesized, possibly dependent on substance P-ergic innervation. Muscarinic cholinergic innervation slightly modulates the contractions but not the relaxations in antigen-induced responses, independently on the presence of the epithelial layer. 4-Aminopyridine induces epithelium-dependent potentiations of contractions to antigen and to serotonin, which involves acetylcholine at one step of the reaction cascade. Epithelial-dependent contracting and relaxing factors are thus suggested in rat trachea.
