Methods
PatientsSix cases of PAD were enrolled, all male patients: 5 cases of TAO, and 1 of ASO. All the patients had a history of intermittent claudication, rest pain, non-healing ischemic ulcers, or all three, and were not candidates for surgical revascularisation. None of the patients had responded to conventional medical therapy for at least 8 weeks. Exclusion criteria were: diabetes mellitus with proliferative retinopathy; malignant disease; recent onset (within 3 month) of myocardial infarction or brain infarction; uncontrolled myocardial ischemia; persistent severe heart failure (ejection fraction <30%); hematological disease; current serious infectious disease; aged older than 80 years; and diseases with life expectancy of less than 1 year.

These results show that microscopic lymphatic vessel-isolated vein anastomosis is a minimally invasive operation, with good long-term effects, making it the treatment of choice for intractable secondary lymphedema of the lower extremities refractory to physiotherapy.
Two cases of necrotizing myelopathy were autopsied; one was complicated with lung carcinoma and the other with chronic type adult T cell leukemia (ATL leukemia). To our knowledge, they were the first cases of their type in Japan. In both cases, necrosis of the spinal cord was observed in the gray and white matter along most of its extent. Marked changes were found in the lumbar segment. The patients were not treated with intravenous cancer chemotherapy or irradiation. Immunohistochemical and electron microscopic examination revealed an extremely strong infection of herpes simplex virus (HSV) type 2. However, HSV type 1 and cytomegalovirus antigens were not detected.
A case of rapidly progressing ascending myelitis was necropsied. Necrosis was present throughout the whole length of the spinal cord and involved both the grey and white matter randomly. The perivascular lymphocytic infiltration in the spinal cord in the present case was more pronounced than that in the previously reported two cases of necrotizing myelopathy associated with malignancy. Using immunoperoxidase staining the presence of herpes simplex virus type 2 (HSV 2) antigen was demonstrated. Electron microscopic examinations revealed large numbers of HSV particles in the spinal cord. HSV 2 may be a common aetiological agent of necrotizing myelopathy and myelitis in Okinawa, an HSV 2 endemic area. In the present case, the necrosis was mainly found in the spinal cord but was also observed, to a very limited extent, in the brain.
The increased serum level of α-fetoprotein (AFP) in a case of renal cell carcinoma, a rare condition of AFP production by mesoderm-derived cells, was evaluated for its lectin reactivity by affinity electrophoresis, followed by the antibody-affinity transfer to nitrocellulose membranes for visualization of separated AFP bands. The AFP of this case was characterized by relative increases of concanavalin A-nonreactive AFP-C1 (60.4%), erythroagglutinating phytohemagglutinin-reactive AFP-P4 (37.8%) and AFP-P5 (46.3%) and Allomyrina dichotoma lectin-nonreactive AFP-A1s (66.7%), and by the total absence of lentil lectin-reactive components, AFP-L2 and AFP-L3. Thus, the lectin-reactive pattern of AFP markedly deviated not only from that of cord serum, but also from those of other malignancies and of fetal kidney cells in culture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
