    Notes: Abstract Keratinocytes were cultured on fibroblast-free dermal substitutes made of type I collagen film (collagen dermal substitute) and an extracellular matrix gel film (matrix dermal substitute), each of which was laid on a lyophilized type I collagen sponge. The morphology of the basal keratinocytes in these three-dimensional culture models of the skin was studied ultrastructurally and immunohistochemically to assess their differentiation to basal cells. The basal keratinocytes in the artificial epidermis cultured on the collagen dermal substitute showed poorly organized tonofibril networks and desmosomes. Neither the tonofibril-hemidesmosome complex nor the lamina densa were detected along the interface, where many cytoplasmic projections of basal keratinocytes were noted. There were no detectable antigens of type IV or VII collagen, LDA-1, or laminin in the interface. Bullous pemphigoid (BP) and 1-2B7B antigens and integrins were expressed along the cytoplasmic membrane and the projections of the basal keratinocytes. A high molecular weight keratin (keratin 1, 68 kDa, 34ΒB4) was detected only in part of the uppermost layers of this artificial epidermis. In contrast, basal keratinocytes in the artificial epidermis on the matrix dermal substitute developed tonofibril networks radiating to desmosomes and hemidesmosomes, under which a primitive lamina densa was present. Basement membrane zone antigens, such as type IV and VII collagens, LDA-1 and laminin were noted along the interface as were 1-2B7B and BP antigens and integrins. Laminin and type VII collagen were also detected along or in the membrane of the endoplasmic reticulum of basal keratinocytes. The high molecular weight keratin was detected in the suprabasal layers of this artificial epidermis, but the basal keratinocytes lacked expression of this epitope as does epidermis in vivo. The artificial epidermis cultured on the matrix dermal substitute had a basal layer of keratinocytes that could be characterized as basal cells, forming junctional structures resembling those of epidermis in vivo.

    Notes: Summary The delay effect on the flap was studied through observation of the vascular changes in the flap which occurred during the course of the delay. 5 mm × 10 mm flaps were prepared on the distal part of the rabbit ear where the cartilage and subcutaneous tissue are very thin. The flaps were raised from the perichondrium and sutured back into their original site. Using a microscope, vascular changes in the flaps in the course of the delay were examined through transmission ray without any medication. Although the vascularity was indistinct due to edema for 3–4 days after raising the flap, longitudinal vessels emerged when the edema subsided. After 2–3 weeks of the longitudinal pattern, the flap vascularity then gradually returned to the original pattern. If the sectioned large transverse vessels again became anastomosed across the vertical incisions, the longitudinal pattern quickly disappeared. Computer analyses were further made on the changes in the vascular pattern, which were photographed at a set interval. It was shown that these visible changes were mostly not derived from neovascularization, but rather a result of dilatation of preexisting vessels, mostly the small ones less than 0.3 mm in diameter.

    Notes: Summary Over the past 5 years, 134 digits were replanted in 85 patients. In 9 patients — 10 digits (11%) — the causation of injury was a motorcycle chain. The significant incidence of this type of injury has prompted us to report the replantation results. Hopefully, this might be used to caution the public against cleaning the chain while it is in motion. The sites of amputation were 5 in Tamai's Zone I and 5 in Tamai's Zone II. All amputated parts were distal to the DIP joint. The digits were replanted with anastomosis of both the artery and the vein. Eight out of the 10 replanted digits survived to give a success rate of 80%. There was no statistical difference between this rate and that for all other replanted digits resulting from various causes in Zones I and II, i.e. 86%. The high success rate suggests that replantation of the chain-amputated digits should be recommended, and the apparently poor conditions of the crush injury are no contraindications for surgery.

    Notes: Summary A wound speculum, or an operator-controlled wound retractor, was devised to facilitate surgery in a narrow and deep field. It is specifically designed to make hemostasis and suturing easy as well as accurate. The blades of the speculum are teflon-coated for electrical insulation on electrocoagulation, and made in the shape of a frame with a narrow opening at the side for the convenience of suturing.
