    Fine Structure of Penetration of Cultured Cells by Isospora canis Sporozoites (1978)

    Notes: SYNOPSIS Monolayers of Embryonic Bovine Trachea (EBTr) cells were inoculated with Isospora canis Nemeséri spcrozoites. As penetration commenced, they were fixed, stained with OsO4-ruthenium red, dehydrated, embedded and sectioned in situ. Examination by electron microscopy revealed that host cell membranes remained intact during penetration. The sporozoites caused an invagination of the cell's plasmalemma until the parasites were entirely within the cell, after which the invagination was sealed by short pseudopodia enclosing the parasite within a membrane-lined vacuole inside the cells. Rhoptries and micronemes, which appeared as branched elements of the same network, became less tortuous near the conoid and often became empty or partially empty during penetration. Concurrent with the appearance of these partially empty rhoptries, vesiculations were seen in the host cell cytoplasm opposite the apical tip of the sporczoite. Constrictions of the sporozoite during entry were probably due to bands of microfilaments beneath the plasmalemma and elsewhere in the cytoplasm of the host cell.

    Ultrastructural features of neuromuscular junctions in the stapedius muscle of Gallus gallus (1978)
    New York, NY : Wiley-Blackwell
    Journal of Morphology 158 (1978), S. 361-365

    Notes: The ultrastructure of neuromuscular junctions in the twitch fibers of the stapedius muscle of Gallus gallus (domesticus) was investigated as part of a series of neurophysiological studies. Among the morphological features observed were elongated end-plates with numerous large and clear synaptic vesicles mixed with larger dense core vesicles and irregular or aperiodic “active sites” in the presynaptic membrane where synaptic vesicles were focused. The most remarkable features of these junctions were large synaptic clefts (50-80 nm) and the absence of junctional folds in the sarcolemmal surface. Unlike the large periodic junctional folds seen in the neuromuscular junctions of frogs and in the fast twitch fibers of the mammalian stapedius, the preparations studied only show small aperiodic invaginations (primitive folds) in the postsynaptic membranes. This morphological feature remains essentially constant from newly hatched to adult chickens. While these smooth junctions are consistent with earlier findings of inconspicuous junctional folds in the twitch fibers of the chicken posterior latissimus dorsi they are unlike those seen in the fast twitch fibers of the mammalian stapedius muscle, or other twitch fibers in general. The morphological findings of the present study may also suggest that the simple, unmodified neuromuscular junctions in the stapedius of Gallus may be a useful preparation for studies of synaptic membrane structures that employ the freeze-fracture technique.

    New Light on Mao: 3. Quemoy 1958: Mao's Miscalculations (1975)

    Notes: Not since the acquisition of the classified military periodical Kung-tso t'ung-hsün has the outside world been given so rich a store of material on the inner rationale behind Chinese foreign policy as is provided by the two volumes of Cultural Revolution compilations, Mao Tse-tung ssu-hsiang wan-sui. Although these documents cannot be authenticated as to accuracy of transcription and are obviously selective as well as edited, they nonetheless provide a wealth of insight into Mao's views on China's external affairs. In particular they throw new light on the 1958 Quemoy crisis with surprisingly frank admissions of miscalculation on Mao's part, both in terms of his objective in the bombardment and his underestimation of the American response thereto.
