Tissue reaction around Schistosoma japonicum eggs was studied after implantation into 3 strains of mice. When freshly laid eggs were implanted into the livers of C57BL/6, CBA/J, and BALB/c mice, the tissue reaction, which could be divided into 3 stages, i.e., abscess formation, inflammatory stage, and fibrous stage, differed in persistence and reactivity… (More)
Fresh eggs, laid bySchistosoma japonicum adult worms in vitro or recovered from tissue after trypsin digestion, as well as non-viable lyophilized eggs were injected into mice via the cecal vein. The freshly laid eggs induced a marked, maximal reaction at 2 weeks after implantation. This reaction was indistinguishable from that seen early in naturally… (More)
This study indicated that the injection of LHRHa was effective for induction of ovulation, and that artificial fertilization should be carried out immediately after ovulation to obtain good results.
The reproductive cycle of devil stinger was investigated by histological observation and hormone analysis. The gonadal development of devil stinger starts between January and February. Spawning season of the fish is from May to August, with peaks from May to June.
Hepatic, pulmonary, and intestinal granuloma formation was comparatively studied in mice implanted with freshly laidSchistosoma japonicum eggs. The liver and the lung showed similar kinetics of tissue reactivity, with the magnitude in the lung being of a significantly lower degree. When the footpad-swelling test was performed, the delayed-type… (More)
Lunar-related spawning in honeycomb grouper was investigated by histological and behavioral analyses. Ovarian development and spawning of the fish were related to lunar periodicity. And also the fish migrated to out side of the reef area and spawned for a few days after the full moon.
The cDNA for glycoprotein hormone (GPH) α-subunit, β-subunits of the FSH (GtH I) and LH (GtH II) were isolated, cloned, and sequenced from sevenband grouper pituitary using RACE PCR. These results show that sevenband grouper has two different types of gonadotropins FSH (GtH I) and LH (GtH II), as other teleosts.
Using a liver model, various granulomatous responses against Schistosoma japonicum eggs were studied in C57BL/6 mice immunized with tissue-extracted eggs prior to challenge implantation with freshly laid eggs. In mice receiving two ip injections of 20,000 eggs, there was little effect on early granuloma formation. Three weeks after implantation, however,… (More)
