OBJECTIVE Stable animal models for refractory peripheral arterial disease are not established. A standardized animal model of hind-limb ischemia is required upon searching effective treatment for this condition. The aim of the study is to verify previously used hind-limb ischemia models to find a standard method. METHODS Using Balb/ca mice six various(More)
The substrate specificity of microbial transglutaminase (MTG) from Streptomyces mobaraensis (formerly categorized Streptoverticillium) was studied using a Streptomyces proteinaceous protease inhibitor, STI2, as a model amine-donor substrate. Chemical modification and mutational analysis to address the substrate requirements for MTG were carried out around(More)
A case of reconstruction of the upper lip with a bipedicled submental flap is described. Although the mobility of the flap was restricted, the arterial blood supply was abundant by altering the single-pedicled flap into a bipedicled flap. This flap is a good color and texture match to the face, and surpasses other flaps in reconstruction of the mustache or(More)
The internal jugular vein (IJV) is used as the optimal recipient for free-tissue transfer in reconstruction following modified radical neck dissection. Some reports documented rare cases of flap compromise following IJV thrombosis, but large sample studies are few. We present cases of emergent exploration and an analysis of factors to improve salvage rates(More)
Tail blood flow is crucial for dissipating body heat in rats. Angiographies are convenient tools to evaluate tail circulation. However, conventional angiographies do not have sufficient sensitivity or spatial resolution for small vessels. Recently, we developed a novel microangiographic system using monochromatic synchrotron radiation and a high-definition(More)
We report a case of a 39-year-old man with a severely deformed hand resulting from an injury sustained in a traffic accident at 2 years of age. A Marjolin ulcer appeared on the cicatricial area 3 years ago. After radical surgery for squamous cell carcinoma, we planned to realign the axis of the ulnarly flexed hand. Prior to surgery, we produced a solid(More)
We conducted an atmospheric pollen survey using a Durham sampler from 1983 through 1998 in Toyama City, Japan. We investigated yearly changes in the pollen season of Japanese cedar Cryptomeria japonica and analyzed the relationships between climatic factors and changes in the pollen counts. The results were as follows: (1) The first day of the Japanese(More)
