    Notes: Summary Sixty dogs with experimental subarachnoid haemorrhage (SAH), repeated SAH, and subarachnoid fibrosis (examined three weeks and three months after SAH, and treated with urokinase or dexamethasone) were examined by scanning electron microscope (SEM). The authors observed the resting and activated macrophages, the erythrophagocytosis, and giant cells in the subarachnoid space after SAH. They consider that the macrophages play an important role in the formation of subarachnoid fibrosis, similar to the role of macrophages in fibrosis in other sites.

    Notes: Summary Scanning electron microscopic observations of the subarachnoid space were made in dogs focussing upon the fibre components in both the normal subarachnoid space and in areas of post-haemorrhagic fibrosis. It was concluded that the fibrous tissue originates from the arachnoid membrane itself, while organized haematoma is considered to form a component of the fibrosis. Perfusion of the subarachnoid space of dogs with a solution of 0.1% Toluidine Blue was also done. This showed that cerebrospinal fluid (CSF) is carried from the subarachnoid space directly to the dural sinuses through a fine string-like structure, which is conceivably one of the collateral CSF absorptive pathways.

    Subarachnoid haemorrhage and communicating hydrocephalus scanning electron microscopic observations (1979)

    Notes: Summary Scanning electron microscopic changes in the subarachnoid space after subarachnoid haemorrhage are described. The obstructive changes were classified into five grades ranging from patency to total obstruction. We report a correlation between communicating hydrocephalus and obstruction above grade 3 in the parasagittal region (p 〈 0.01) and the lateral cerebral fissure (p 〈 0.05).

    Changes in the subarachnoid space after experimental subarachnoid haemorrhage in the dog: Scanning electron microscopic observation (1977)

    Notes: Summary The possible changes in the subarachnoid space after subarachnoid haemorrhage were studied in animals by using a scanning electron microscope (SEM). About 1 ml/kg of autogenous blood was injected intracisternally in 36 adult mongrel dogs to investigate changes in the subarachnoid space, over periods ranging from immediately after the injection to as long as 6 months. We have come to the conclusion that the injected blood disappears in about one to two weeks; the fibrosis or thickening of the arachnoid membrane appears in one to three weeks, and then returns to normal in a month in instances of rapid recovery, but there are some cases in which fibrosis persists for a long period and becomes chronic. The fact that an increase of fibrous tissue was found in the parietal region, where the injected blood had hardly reached, appears to indicate that the fibrosis is not always limited to the site of the haemorrhage but can occur in remote regions. We also discuss the usefulness of the SEM in the observation of the subarachnoid space, and the finding that vascular specimen preparations can be made by perfusing the brain with 2–10% phosphate-buffered formaldehyde solution.

    High-spin states in107Sn (1993)

    Notes: Abstract High-spin states in107Sn were studied using the reaction54Fe(56Fe, 2pn)107Sn. An odd-parity band was identified as based on thevh 11/2 orbit by measuring theγ-ray linear polarization. Also were confirmed the excited states based on thevd 5/2 andvg 7/2 orbits. The halflives of the 17/2+ and 11/2− states were measured to be 0.25(4) ns and 28(11) ps, respectively. The experimental level structure and its interpretation were in good agreement with a shell model calculation.

    Notes: Abstract High spin states in the isotopes105,103In have been studied by in-beamγ-ray techniques. The reaction51V(58Ni, 2p 2n) populated those states in105In. A measurement of the linear polarizations ofγ-rays has revealed a negative-parity band in105In. The reaction48Ti(58Ni,p 2n) produced the isotope103In, which has showed an yrast spectrum similar to that observed in105In. The lifetimes of the 19/2+ and 17/2+ states in107,105In have been measured by the recoil distance method;T 1/2(19/2+)=27±4 ps andT 1/2(17/2+)=1.1 −0.3 +0.6 ns for107In,T 1/2(19/2+)=4±2 ps andT 1/2(17/2+)=0.33±0.10 ns for105In.

    Nuclear structure of the yrast 6+, 10+ and 14− states in106Sn (1994)

    Notes: Abstract The nuclear precession of106Sn in the 6+ state was measured relative to that of108Sn by the IPAD method: θ(6+;106Sn)/θ(6+;108Sn)=1.06(33). Available data on the 6+ state in108Sn giveg (6+;106Sn)=− 0.14(9), which is consistent with the seniority ν=2 configuration: ({ie133-01}). B(E2; 10+→ 8+) was measured to be 6.4(10) W.u. for106Sn and 0.62(5) W.u. for108Sn. This difference could not be explained by the ν≦4 configurations. The {ie133-02}→13− transition turned out to be an M1/ E2 mixed transition and so the yrast I=14 state was identified with a state of the νh11/2 band.
