    Notes:
    Oocysts of Eimeria acervulina Tyzzer, 1929 were collected at the time of their first massive discharge into the chick intestine, and isolated in the cold by means of continuous centrifugal flotation in high-density media. Maximum numbers (90%) of sporoblastic oocysts were obtained by incubating at 30°C for 10 hr and sporulation was considered complete within 20 hr. The initial Qo2 (dry-weight basis) of 9.5 decreased linearly to 〈 i/3 this value in 20 hr, and more slowly thereafter to very low levels. The QCO2 was higher than Qo2 only during the first 10 hr. A 15% decrease in dry weight in 15 hr was due chiefly to disappearance of alkali-stable carbohydrate, probably identical with glycogen. In the later stages carbohydrate was resynthesized. Lipids were not oxidized during sporoblast formation, but disappeared rapidly betweem 10 and 30 hr. Total nitrogen remained constant, indirect evidence suggesting that protein was not used to supply oxidative energy The change-over from carbohydrate to fat metabolism corresponded with observed changes in the respiratory quotient, and also with near-completion of sporulation. Apparently carbohydrate provided the energy needed for the earlier stages of sporulation, whereas oxidation of lipids supported the teal stages as well as the metabolism during dormancy.

    Notes:
    Abstract Whole blood calcium activity, total plasma calcium, pH, pCO2, and plasma albumen concentrations were measured in ten patients undergoing cardiopulmonary bypass. Since calcium activity was the same before and after bypass, routine monitoring of calcium activity is only recommended when large blood transfusions are given. Depression of myocardial contractility post-bypass is rarely related to a low blood calcium activity.

    Summary The distribution of nerve growth factor-like immunoreactivity has been examined in the embryonic mouse with special reference to the CNS. The intensity of the immunoreactive stain was found to be greatest on embryonic days 15 and 16. The antigen is widespread and present in high concentrations in both the PNS and CNS. Most intense staining was detected in cranial nerve tracts, hippocampus, developing white matter of the spinal cord and tegmentum. Lower intensities were found within diencephalic regions, spinal cord grey matter, medullary fibre tracts and cerebellum. These results support the increasing evidence suggesting that the trophic molecule nerve growth factor has an important role to play in the development of central as well as peripheral neurons.

    Abstract Previous studies have demonstrated that various cell types can produce and secrete polyornithine-attachable neurite promoting factors when cultured. This study describes an endogenous source of polyornithine-attachable neurite promoting factors. The active material extracted from an avian smooth muscle, the expansor secundariorum, is able to enhance neurite outgrowth from embryonic chick sympathetic neurons when applied to a polyornithine substrate. Unlike other polyornithine attachable factors, the material is also able to support the neurons for at least 72 hr in the absence of any added survival factors. Partial purification of the active material was achieved by affinity chromatography on polyornithine-Sepharose. The findings support the proposal that neurite promoting factors may have a definite physiological role in addition to their well established in vitro activity.

    Notes:
    Summary The contractile properties of single rat cardiac cells isolated from normal and hypertrophied right ventricles have been investigated. These have been correlated with the isoenzyme composition of the whole ventricle. Right cardiac hypertrophy was induced by injecting rats with monocrotaline, an alkaloid which induces severe pulmonary hypertension. Ca2+ ATPase activity and myosin alpha-chain percentage were decreased in the hypertrophied right ventricle as compared with that of control rats. The contraction amplitude and speed of shortening of the isolated cells were measured using an inverted microscope, video camera, and edge detection device. Cells from the hypertrophied ventricle showed a significantly decreased contraction amplitude and speed of shortening in maximally activating concentrations of isoprenaline. A statistically significant correlation existed between myosin alpha-chain percentage and both contraction amplitude and speed of shortening in maximum isoprenaline. This was truc when all cells studied were included, as well as within the hypertrophy group. A similar, although not always statistically significant, correlation was observed when cells were maximally activated with calcium. These results suggest that changes in isomyosin pattern that occur in cardiac hypertrophy produce alterations in contraction amplitude and speed of shortening which can be detected in single cells isolated from the hypertrophied ventricles. Isolated cells appear to give responses representative of the function of the whole heart.

    Description / Table of Contents:
    Zusammenfassung Es wird eine Methode beschrieben zur kontinuierlichen Messung des extrazellulären Raumes in isolierter Ventrikelmuskulatur. Die Größe des Extrazellulärraumes variiert mit dem kontraktilen Zustand des Muskels. Eingriffe wie Stillstellung, Mangan und Azidose reduzieren die Kontraktilität und vergrößern den Extrazellulärraum. Barium, Ouabain und Hypoxie verursachen Kontraktur und verkleinern den Extrazellulärraum. Diese Änderungen sollten berücksichtigt werden, wenn intrazelluläre Elektrolyte in isolierten Ventrikelpräparaten bestimmt werden.
    Notes:
    Summary A method is described with which the extracellular space of isolated ventricular muscle can be measured accurately and continuously in the same muscle. The size of the extracellular space is shown to vary with the contractile state of the myocardium. Interventions such as quiescence, manganese and acidosis reduce myocardial contractility and increase the size of the extracellular space. Barium, ouabain and hypoxia cause contracture and reduce the size of the extracellular space. These changes should be taken into account when measuring intracellular electrolytes in isolated ventricular preparations.

    Notes:
    Abstract Myocytes from failing human ventricle contract and relax more slowly than those from non-failing. This has been suggested to result from the lowering of basal cyclic AMP level in failing myocardium, and the consequent withdrawal of a tonic lusitropic effect. We present data to support this hupothesis by demonstrating that the acceleration of contraction and relaxation by β-adrenoceptor stimulation is greater in myocytes from failing than nonfailing heart. This is despite the desensitisation of the inotropic effect of isorenaline in the same failing cells. Following β-adrenoceptor stimulation, speeds of contraction and relaxation are normalised in myocytes from failing heart, with final values not significantly different from non-failing.
