    A mechanism of “red-tide” formation (1982)
    Springer
    Marine biology 70 (1982), S. 267-273

    Notes: Abstract Three semi-continuous culture experiments were conducted by using natural algal populations [dominants: Skeletonema costatum, Thalassiosira sp., Gymnodinium sp., Heterosigma sp. (formerly called Olisthodiscus luteus) and Eutreptiella sp.] collected from Tanigawa Harbor, Japan, where red-tides occurred occasionally. The effects of macro- and micro-nutrients onto the growth of different species of algae were specifically evaluated by a dialysis bag culture technique. Two types of responses for nutrients were clearly observed; macro- and micro-nutrient dependency. The former group includes S. costatum, Thalassiosira sp. and Eutreptiella sp. which mainly stimulated their growth by macro-nutrients. Heterosigma sp. was in the latter group which was stimulated by micronutrients. Gymnodinium sp. showed an intermediate type. A red-tide of Heterosigma sp. formed during the experiment in the harbor and is discussed with the results of the present culture experiments and some field observations.

    Abundance and life history ofNeomysis intermedia Czerniawsky in Lake Kasumigaura (1982)

    Notes: Abstract Weekly observations ofNeomysis intermedia in Lake Kasumigaura showed two major peaks in abundance during spring and autumn (more than 104 individuals m−2) and minimum levels in summer and winter (less than 103 individuals m−2). Their increase in abundance followed a high egg ratio, suggesting that the increase in abundance was caused by a high reproductive rate. Major contributors to mysid population decreases include fish predation and commercial fisheries, and possible horizontal migration of the mysids. N. intermedia showed two types of life history in the lake. One type (overwintering generation) has a life span of about 6–7 months and produces about 27 eggs per brood. Another, appearing from spring to autumn, matures in 3–6 weeks at a smaller size, and produces 12 eggs per brood. The reproductive season ofN. intermedia was continuous from March through November.

    Hepatic tyrosine aminotransferase in tyrosinaemia type II (1982)
    Springer
    Journal of inherited metabolic disease 5 (1982), S. 229-230

    Topics: Medicine
    Notes: Abstract Tyrosinaemia type II (Richner-Hanhart's syndrome), first reported by Wadmanet al. (1968), is characterized by a highly elevated level of tyrosine in blood and corneal ulcer, dermal hyperkeratosis and mental retardation. Fellmanet al. (1969) showed that this disease was caused by the defect of the cytosolic tyrosine aminotransferase of the liver. We now report a case of this disease with enzymological studies of the biopsied liver.
