ABSTRACT: Recently, a serious disease spread extensively in aquaculture sites of the ascidian Halocynthia roretzi in Korea. To understand circumstances of ascidians in Korean aquaculture sites, residue levels of organotin compounds were analyzed, and detection of a marine birnavirus (MABV) in tissues of H. roretzi was attempted. Korean H. roretzi showed high concentrations of butyltins (mono, di, and tributyltins), especially in the gill, hepatopancreas, and digestive tract. However, there was no significant difference in the residues of butyltins in the hepatopancreas between diseased and non-diseased ascidians. The positive rate of MABV detection was high in the hepatopancreas, but also no significant difference was observed between diseased and non-diseased individuals. These observations suggest that an accumulation of tributyltin and a latency of MABV in H. roretzi tissues does not directly relate to the occurrence of the disease. 相似文献

To clarfity whether polyunsaturated fatty acid (PUFA) oxidation is involved in the mechanism of acetaminophen (APAP)-induced apoptotic cell death, the production and localization of PUFA oxidation markers N(ε)-propanoyl-modified lysine, N(ε)-hexanoyl-modified lysine, 4-hydroxyhexenal-modified histidine and crotonaldehyde-modified lysine were evaluated in the development of APAP-induced liver injury. The immunoexpression of these markers in the liver was examined up to 24 hr post-APAP intraperitoneal injection in rats (1 g/kg body weight). The histopathological changes in the liver appeared 3 hr after APAP injection and became exacerbated with time. Proapoptotic protein Bax immunoreactivity was first detected in the degenerative hepatocytes 3 hr after the injection and areas positively immunostained for Bax reached a peak level at 6 hr, and then decreased at 12 and 24 hr. There was a significant increase in the TUNEL-positive rate at 12 and 24 hr. Immunohistological expression of all these oxidation markers was first detected in the degenerative hepatocytes 3 hr after the injection, and earlier than the occurrence of hepatocyte apoptosis. Immunohistochemical expression of these markers were observed in almost all degenerative hepatocytes 3-24 hr after APAP injection. Areas positively immunostained for these markers reached a peak level at 6 hr, and then decreased at 12 and 24 hr. The results thus suggest that the generation of PUFA oxidation markers may be the signature of early events preceding the induction of liver cell apoptosis and thus useful for early detection of oxidative stress-related liver cell injury. 相似文献

The lumber from sugi plantations in Japan displays large intra- and intertree variation in mechanical properties, even within
a stand. These variations seem to be induced by the effects of the characteristics of cultivars as well as the effects of
growth traits on mechanical properties. Therefore, the effects of growth traits on mechanical properties per cultivar need
to be precisely examined. In this study, we focused on the effects of growth traits, especially height-to-diameter ratio (H/D
ratio), on stem stiffness per cultivar. Sixteen cultivars were classified into three groups according to the relationships
between stem stiffness and growth traits. In cultivars that showed a close correlation between growth traits and stem stiffness,
it was assumed that stem stiffness could be controlled to a certain extent by silvicultural practices using the H/D ratio
as an indicator. In cultivars that showed a weak correlation between growth traits and stem stiffness, selecting cultivars
for the production of logs with higher mechanical properties seemed to be effective; in this study, Kumotoshi, Tanoaka, and
Edanaga were found to be suitable. Tree age and site index may be important factors for producing wood with higher mechanical
properties. 相似文献

Reactions involved in blue-green discoloration in a mixture of onion (Allium cepa L.) and garlic (Allium sativum L.) were investigated. Vivid-blue color was successfully reproduced by using a defined model reaction system comprising only trans-(+)-S-(1-propenyl)-L-cysteine sulfoxide (1-PeCSO) from onion, S-allyl-L-cysteine sulfoxide (2-PeCSO) from garlic, purified alliinase (EC 4.4.1.4), and glycine (or some other amino acids). Four reaction steps identified and factors affecting the blue color formation were in good agreement with those suggested by earlier investigators. When crude onion alliinase was used in place of garlic alliinase, less pigment was formed. This result was explained by a difference in the amount of thiosulfinates, colorless intermediates termed color developers, yielded from 1-PeCSO by these enzymes. 相似文献

Previous studies have shown the physiological significance of dietary conjugated linoleic acid (CLA) in various experimental animals and in human beings. One of the important problems to better elucidate is the difference between triglyceride (TG) and free (FFA) dietary CLA. Here, using splenocytes, this study assesses how TG- and FFA-CLA modulate immunoglobulin and various cytokine productions. In this study, C57BL/6N mice were fed an experimental diet containing 0% CLA, 0.1 or 1% FFA-CLA, or 0.1 or 1% TG-CLA for 3 weeks. The production of immunoglobulin tended to be up-regulated by 1% FFA-CLA. As a result of protein array analysis using the supernatant from splenocytes cultured with no CLA, 1% FFA-CLA, and TG-CLA, some cytokine production was shown to be remarkably regulated by dietary FFA- and TG-CLA. A total of 32 cytokines were examined, and 11-14 produced cytokines that were 2-fold up-regulated as compared with control for FFA- or TG-CLA, respectively. Especially, the production of IL-9 and MCP-5 and other cytokines was remarkably up-regulated by both FFA- and TG-CLA. In addition, seven cytokines were 2-fold down-regulated by TG-CLA. These data show that there is a slight but significant difference between the functionalities of FFA- and TG-CLA. 相似文献

High-resolution images of the surface of asteroid Itokawa from the Hayabusa mission reveal it to be covered with unconsolidated millimeter-sized and larger gravels. Locations and morphologic characteristics of this gravel indicate that Itokawa has experienced considerable vibrations, which have triggered global-scale granular processes in its dry, vacuum, microgravity environment. These processes likely include granular convection, landslide-like granular migrations, and particle sorting, resulting in the segregation of the fine gravels into areas of potential lows. Granular processes become major resurfacing processes because of Itokawa's small size, implying that they can occur on other small asteroids should those have regolith. 相似文献

We evaluated the anti-tumor activities of the oral administration of fucoidan extracted from Cladosiphon okamuranus using a tumor (colon 26)-bearing mouse model. The materials used included low-molecular-weight fucoidan (LMWF: 6.5–40 kDa), intermediate-molecular-weight fucoidan (IMWF: 110–138 kDa) and high-molecular-weight fucoidan (HMWF: 300–330 kDa). The IMWF group showed significantly suppressed tumor growth. The LMWF and HMWF groups showed significantly increased survival times compared with that observed in the control group (mice fed a fucoidan-free diet). The median survival times in the control, LMWF, IMWF and HMWF groups were 23, 46, 40 and 43 days, respectively. It was also found that oral administration of fucoidan increased the population of natural killer cells in the spleen. Furthermore, from the results of the experiment using Myd-88 knockout mice, it was found that these effects are related to gut immunity. These results suggest that fucoidan is a candidate anti-tumor functional food. 相似文献
