Free transfers of the distal parts of the second toe for reconstruction of distal phalangeal losses of the fingers were successfully carried out. This method is believed to be the best for functional and cosmetic reasons, but major postoperative vascular problems exist. To overcome these problems, multiple vascular anastomoses were employed at operation. The indications for this method are limited in Japanese patients, and its use depends on the patient's age, sex, religious beliefs and the shape of the second toe.
A case of hepatic angiomyolipoma in a 61-year-old woman is reported. Findings on ultrasound (US), computed tomography (CT), and magnetic resonance (MR) imaging are presented and the usefulness of breath hold 2D FLASH Gd-dynamic imaging with fat saturation is discussed.
We isolated Gluconobacter oxydans T-100 that had an activity to produce 2-KLGA from D-sorbitol; however, the yield of 2-KLGA was quite insufficient. Therefore, enzymes involved in the biosynthesis of L-sorbosone and 2-KLGA, L-sorbose dehydrogenase (SDH) and L-sorbosone dehydrogenase (SNDH), respectively, were purified from G. oxydans T-100. A genomic library of G. oxydans T-100 was screened to clone both genes for SDH and SNDH based on their amino acid sequences. SNDH and SDH were encoded in sequential open reading frames with 1497 and 1596 nucleotides, respectively, which were verified by the expression in Escherichia coli. The amino acid sequence of SDH and SNDH showed close similarity with E. coli choline dehydrogenase (CDH) and betaine-aldehyde dehydrogenase (BADH), respectively, which cooperatively play a key role for conferring osmotic tolerance. Because the yield of 2-KLGA by G. oxydans introduced with the genes for SDH and SNDH were insufficient, replacement of the promoter with that of Escherichia coli tufB1 in combination with chemical mutagenesis by N-methyl-N'-nitro-N-nitrosoguanidine resulted in improvement of the production level.

We describe a case of cavernous hemangioma of the adrenal gland in which MR imaging showed low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, and dynamic MR imaging using Gd-DTPA showed late and delayed enhancement, allowing definitive diagnosis.
The ultrasound and color Doppler sonography characteristics of inflammatory pseudotumor (IPT) of the spleen are nonspecific, and thus preoperative diagnosis of the tumor is difficult. We describe a case of IPT of the spleen studied with ultrasound, color Doppler sonography, CT, and MRI, and we report the usefulness of US and MRI findings of the tumor.
