    Notes: The relationship between the conformability of adhesive tape, the mechanical property of the adhesive tape not to interfere with skin movement, and irritation of the skin was investigated. In order to assess the conformability of adhesive tape to the skin, a uniaxial method employing film strips connected to a strain gauge was used to measure the elastic properly of the skin, with or without application of various elastic tapes. The tension loaded on the strain gauge was measured while the skin was extended by 15% of its original length in a direction across the humeral axis on the flexor side of the upper right arm. The most elastic adhesive tape showed the best conformity to the skin. The same adhesive tapes were applied on the flexor side of both upper arms so that the tape held a piece of sanitary cotton in place for 24 h. Dermal irritation was not so remarkable in the skin under the inner part of the tapes. On the other hand, the skin reaction was much more severe on the skin under the edge portion of the applied tape which showed poor conformability to the skin. These findings seemed to indicate that the skin reaction was caused by localized distortion of the skin under the edge portion of the applied tapes, during movement of the underlying muscle. Actually, the distortion of the skin surface was great in the areas immediately outside the edge of the applied tape. In conclusion, adhesive tape conformable to skin movement reduced localized distortion of the skin during application, resulting in low irritation at the edge of the applied tape.

    Seasonal variation in adhesive tape stripping of the skin (1999)

    Notes: Background/aims: The seasonal variation in various properties of adhesive tapes on the skin was evaluated.Methods: In February, April, and August, five general-purpose adhesive tapes were applied on the forearms of 12 healthy male volunteers for 24 h. The dermal peeling force, the accumulation of fluid, the amount of stripped corneocytes, and the dermal reaction at 1 h after removal of the tapes were evaluated.Results/Conclusions: The various properties of adhesive tapes on the skin were closely related to the accumulation of fluid beneath the applied tape. Because the accumulation of fluid was significantly higher in summer than in winter, the dermal peeling force was lower in summer than winter. However, the number of stripped corneocytes and the dermal reaction of the inner area under the applied tapes were larger in summer than in winter. Though tha dermal peeling force, the accumulation of fluid, and the number of stripped corneocytes are generally considered as dermal irritation factors, the accumulation of fluid and the number of stripped corneocytes may exert a great influence on the seasonal variation in dermal irritation. On the other hand, the dermal reaction of the edge section had no tendency to vary with season. Because the edge reaction should be caused by interference with skin movement by the stiff backing or the adhesive, it seems to be uninfluenced by the accumulation of fluid.

    Time-dependent changes in dermal peeling force of adhesive tapes (1999)

    Notes: The dermal peeling force of acrylic adhesive tapes was evaluated in relation to the accumulation of fluid and the number of stripped corneocytes.〈section xml:id="abs1-2"〉〈title type="main"〉Methods:Two kinds of tapes that had different water vapor permeability were applied on the flexor side of both forearms in eight healthy male volunteers. The dermal peeling force was measured at 1, 4, 8 and 24 h after application of the tapes. Simultaneously, the electrical conductance of the skin beneath the applied tape and the total area of corneocytes stripped on the adhesive surface of the removed tape, instead of the adhesive area of the tape relative to the skin surface, were measured.〈section xml:id="abs1-3"〉〈title type="main"〉Results/Conclusions:The dermal peeling force of the permeable tape gradually increased and that of the occlusive tape decreased. The increase in the former could be caused by the increase in the adhesive area of the tape relative to the skin surface, and the decrease in the latter could be caused by reduction of the bonding force among the corneocytes themselves, according to hydration.

    The accessory optic system of the rabbit, cat, dog and monkey: a whole-mount HRP study (1988)

    Notes: Summary The three-dimensional fiber pathways of the accessory optic system in the rabbit, cat, dog and monkey were studied in whole-mounted preparations of the diencephalon and the midbrain, without sectioning, by anterograde labeling of retinal axons with horseradish peroxidase (HRP). HRP histochemical studies on alternate serial coronal sections were also performed. The rabbit accessory optic system exhibited two fasciculi (the inferior fasciculus, and the superior fasciculus consisting of the anterior fibers and the posterior fibers) and three terminal nuclei (the medial terminal nucleus, and the anterior and posterior porcions of the lateral terminal nucleus), but lacked the dorsal terminal nucleus. In the cat and dog, only the posterior fibers of the superior fasciculus were detected. The inferior fasciculus and the anterior fibers of the superior fasciculus were absent. The medial terminal nucleus and the posterior portion of the lateral terminal nucleus were commonly observed in the cat and dog. The cat accessory optic system possessed the dorsal terminal nucleus, and the dog accessory optic system possessed the anterior portion of the lateral terminal nucleus. The monkey (Macaca fuscata) accessory optic system consisted of the posterior fibers of the superior fasciculus, but blacked the inferior fasciculus and the anterior fibers of the superior fasciculus. Most of the posterior fibers terminated in the well-developed posterior portion of the lateral terminal nucleus located on the upper surface of the cerebral peduncle. A small number of posterior fibers projected to the poorly-developed medial terminal nucleus. Based on these findings, species differences in the mammalian accessory optic system were discussed.

    Serum Protein Exudation in Chronic Subdural Haematomas: a Mechanism for Haematoma Enlargement? (1998)

    Notes: Summary A study was conducted to investigate the role of serum protein exudation in the aetiology of chronic subdural haematoma (SDH). Scintigraphy after intravenous injection of 99mTc-labelled human serum albumin (HSA) was performed in three patients with chronic SDH and a patient with subdural effusion. In nother 60 haematomas, the amounts of total protein and albumin as indices of serum exudation were measured, and then compared among low-density, iso-density and high-density haematomas. Accumulation of 99mTc-HSA in the haematoma cavity was seen 6 h after isotope injection and became more evident at 24 h. However, the protein concentrations and albumin ratios in the haematomas exhibited a reciprocal relationship, suggesting that not all the protein in the haematomas was derived from serum exudation. The higher the total protein concentration in the haematoma became, the higher the haematoma density which was observed on CT. The albumin concentration in low-density haematomas was lower than that in iso-density and high-density haematomas, whereas no significant difference was seen between the latter two haematoma types. These results provide morphological evidence for serum protein exudation into the haematoma cavity, and therefore it is possible that serum protein exudation plays a role in the progression of chronic SDH and is related to changes in haematoma density on CT.

    Notes: Abstract We performed helical computed tomography with contrast injection into feeding arteries through a selectively introduced microcatheter to provide precise definition of the vascular and bony structure of the spine in patients with spinal arteriovenous fistula. This selective CT arteriography reliably showed structures including abnormal epi- and intradural feeding arteries, the fistula, perimedullary draining veins and surrounding vertebrae preoperatively with a minimal contrast medium load. This technique can facilitate safe, minimally invasive surgical obliteration of the fistula and a favorable outcome.
