    Ovarian structure and batch fecundity in Lophiomus setigerus (1998)

    Notes: The ovarian structure and batch fecundity of anglerfish Lophiomus setigerus were examined from specimens collected in the East China Sea during March 1991 to September 1995. The right and left ovarian lobes were connected at their posterior ends. Stalk-like ovigerous lamellae protruded from the ovarian wall. During the spawning season, gelatinous material was secreted from the epithelia of both the ovigerous lamellae and ovarian wall, and these epithelia showed morphological changes accompanying the ovarian maturation cycle. Tertiary yolk, migratory nucleus, and mature stage oocytes occurred in the ovaries between May and November, when females with postovulatory follicles and developing vitellogenic oocytes were collected also. These results suggested an extended spawning season during which females undergo repeated spawnings. When the most advanced oocytes attained the secondary yolk stage, they formed a batch that separated from the adjacent group of smaller oocytes. Batch fecundity (F) in 20 females with secondary yolk stage ovaries was related to total length (LT, mm) as F= 556.2 LT1.157 (300≤LT≤396).

    Reproductive cycle and sexual maturity of the anglerfish Lophiomus setigerus in the East China Sea with a note on specialized spermatogenesis (1998)

    Notes: The reproductive cycle and sexual maturity of the anglerfish Lophiomus setigerus were examined. Spermatids were released from the germinal cysts into the lumina of the seminal lobules, and both spermatids and spermatozoa were present in the lumina of the seminal lobules and sperm ducts. Spermatogenesis and vitellogenesis occurred throughout most of the year. The testes of males were full of spermatozoa throughout the year, with spawning from May to November. Males and females reached sexual maturity at a mean total length and age of 178 mm, 3.3 years and 303 mm, 6.1 years, respectively. There were clear seasonal cycles in the gonadosomatic index (IG) and hepatosomatic index (IH) in females. The mean IG of females increased rapidly with ovarian development while the mean IH decreased from the middle of vitellogenesis to final maturation. Mean values of IG and IH in males increased with testicular development.

    Multilineage involvement and erythropoietin-"independent" erythroid progenitor cells in a patient with systemic mastocytosis (1998)
    Springer
    Annals of hematology 77 (1998), S. 183-186

    Notes: Abstract  We report on a patient with systemic mastocytosis with an activating point mutation of the c-kit gene. This mutation was identical to the c-kit mutation recently described by other groups. Additionally, we found that in this patient the mutation was also present in myeloid and erythroid lineages, indicating a multilineage involvement and suggesting a clonal origin of the disease similar to that described in other myeloproliferative disorders. The erythroid involvement was further demonstrated by the presence of erythropoietin-"independent" erythroid progenitor cells.

    Neuroradiological findings in the carbohydrate-deficient glycoprotein syndrome (1995)

    Notes: Abstract The carbohydrate-deficient glycoprotein syndrome is a newly recognised genetic disorder characterised by mental retardation, liver disfunction during infancy, cerebellar ataxia and atrophy, polyneuropathy, growth retardation, stroke-like episodes, and the appearance of carbohydrate-deficient fractions of multiple glycoproteins in the serum. The neuroradiological findings have been known as features of olivopontocerebellar atrophy. However, whether the abnormalities in the cerebellum and brain stem progress after birth is not known. We have carried out serial CT and MRI on three Japanese patients with this syndrome at different ages. A small cerebellum, with peculiar enlargement of the cisterna magna, and a small brain stem are present in infancy and atrophy of the anterior vermis and from before backwards in the cerebellar hemispheres seem to progress throughout early childhood.
