[A case of bow hunter's stroke caused by bilateral vertebral artery occlusive change on head rotation to the right].

We report a case of bow hunter's stroke caused by simultaneous bilateral vertebral artery occlusive changes at the right C3-4 and the left C1-2 level on head rotation to the right side. The pathogenesis and surgical treatment for this particular case are discussed. A 61-year-old male with cervical spondylosis repeatedly experienced vertebrobasilar insufficiency when he rotated his head over 60 degree from the mid-position to the right side.

Malignant fibrous histiocytoma of the pancreas.

An extremely rare case of malignant fibrous histiocytoma in the pancreas is reported. A 70-year-old man complained of upper abdominal discomfort. A tumor in the head of the pancreas was demonstrated by ultrasonography and computed tomography.

Prevalence of hepatitis C virus antibody in an area endemic for hepatitis B virus and human T cell leukaemia virus.

To clarify the prevalence of concurrent infection with hepatitis C virus (HCV), hepatitis B virus (HBV) and human T cell leukaemia virus (HTLV), we measured HCV antibody in the population of a district endemic for HBV and HTLV infection. Blood samples were collected in June 1990 from 579 inhabitants of four islands of Uwa Bay in the southwest of Ehime Prefecture in Japan. Anti-HCV antibody against C100-3 protein was detected using an enzyme-linked immunosorbent assay kit (Ortho Diagnostics).

[Inhibitory factors of calcium oxalate crystal growth in urinary macromolecules].

We studied the inhibitory effect of urinary glycosaminoglycans (GAGs), in the natural form, on calcium oxalate crystals. Control urine was collected from five healthy subjects and filtered by 5 microns and 0.22 micron membranes.

[A case report of a solid and cystic tumor of the pancreas in a 33-year-old woman].
