A certain marine catenate dinoflagellate tentatively applied for detecting carcinogens
Autor: Tomoki Yano, Jiann-Chu Chen, Shinya Ishio
Publikováno v: NIPPON SUISAN GAKKAISHI. 43:277-288
A marine catenate dinoflagellate having been tentatively applied by the present authors for detectiong carcinogens has been regarded to be Polykrikos schwartzi BUTSCHLI. However, this species does not belong to the genus Polykrikos for reasons that i

Effects of water hardness on the toxicity and accumulation of cadmium in eggs and larvae of medaka Oryzias latipes
Autor: Hisaki Nakagawa, Shinya Ishio
Publikováno v: NIPPON SUISAN GAKKAISHI. 55:321-326
Effects of water pH on the toxicity and accumulation of cadmium in the eggs and the larvae of Oryzias latipes were studied. Within the range of pH 4.5-7.0, the toxic effects of Cd2+ on the eggs increased in groups with a lower pH. On the contrary, th

Study on the scarcity of red tide in the eutrophicated waters of Ariake Bay. III. Conversion of AlPO4-P to Fe-bound P in sea sediments
Autor: Shinya Ishio, Masato Kuwahara, Hisaki Nakagawa
Publikováno v: NIPPON SUISAN GAKKAISHI. 52:901-911
Fe-bound P in the sediment was suspected to be the cause of the frequent red tide in Hakata Bay in summer, because it releases PO43- into the upper water when H2S is generated in the sediment. Thus, the contents of Fe-bound P were measured by applyin

Toxicity of cadmium and its accumulation on the egg and larva of Medaka Oryzias latipes
Autor: Shinya Ishio, Hisaki Nakagawa
Publikováno v: NIPPON SUISAN GAKKAISHI. 54:2153-2158
Toxicity and accumulation of cadmium to the eggs and larvae of medaka Oryzias latipes were examined in cadmium concentrations of 0.1-4.0 ppm. The eggs were not adversely affected by the cadmium concentrations of 0.1-2.0 ppm, but their hatchability si

Steroid hormone metabolites in fish urine. I. Identification of androsterone, etiocholanolone, and dehydroepiandrosterone isolated from the urine of carp
Autor: Shinya Ishio, Tomoki Yano
Publikováno v: NIPPON SUISAN GAKKAISHI. 44:1023-1028
The analysis of human urinary steroid metabolites has been widely used to diagnose the functional diseases of adrenal cortex, testis, ovary, and pituitary. This method may be applicable to elucidate some physiological effects of agricultural chemical

Study on the scarcity of red tide in the eutrophicated waters of ARIAKE bay - I. Dissolution of phosphate ion from bottom mud by hydrogen sulfide
Autor: Shinya Ishio, Keizo Kondo
Publikováno v: NIPPON SUISAN GAKKAISHI. 46:977-989
Soluble sulfide such as hydrogen sulfide was made clear to be able to become the cause of the dissolution of phosphate ion from sea bottom mud. The phosphate which is capable of liberating phosphate ion from the bottom mud into water when met with so

Study on the scarcity of red tide in the eutrophicated waters of Ariake Bay - V. Separation of dinoflagellate growth inhibitor from sea sediment
Autor: Hisaki Nakagawa, Shinya Ishio, Takashi Nishimoto
Publikováno v: NIPPON SUISAN GAKKAISHI. 54:1175-1181
In order to isolate dinoflagellate growth inhibitor (DGI) which was indicated to distributes broadly in the sediments of Ariake and Hakata Bays, the acetone extract was prepared form the sediment of the most eutrophicated point in Hakata Bay. The ext

Steroid hormone metabolites in fish urine. III. Corticosteroid metabolites in carp urine
Autor: Tomoki Yano, Shinya Ishio
Publikováno v: NIPPON SUISAN GAKKAISHI. 44:1405-1410
The present study deals with the identification of corticosteroid metabolites in the urine of carp, Cyprinus carpio. Samples of carp urinary steroids obtained by β-glucuronidase hydrolysis were converted to methoximetrimethylsilyl (MO-TMSi) derivati
