| induction of two forms of eel cytochrome p450 1a genes by 3-methylcholanthrene. | : in eel (anguilla japonica), exposure to polyaromatic hydrocarbons such as 3-methylcholanthrene leads to induction of two cyp1a enzymes, cyp1a1 and cyp1a6. we studied the time course and tissue specificity of induction of messenger rnas for cyp1a1 and cyp1a6 in eel by administering 3-methylcholanthrene intraperitoneally. in both cases, the drug induced a rapid increase of mrnas and biphasic expression. in the liver, mrna levels of cyp1a1 and cyp1a6 increased 22-fold at 3 hours and 27-fold at 6 ... | 1999 | 10489409 |

| protease activity appeared after trypsin treatment of the purified vitellogenin from eel anguilla japonica. | density gradient ultracentrifugation and anion-exchange chromatography combination were effective for the purification of the eel vitellogenin from the plasma of estradiol-treated eels. the vitellogenin was very high density glycolipoprotein (p = 1.27 g/ml) and its apolipoprotein was m(r) 196 k in both reduced and non-reduced conditions by sds-page. the major lipid component was phospholipid. the n-terminal amino-acid sequence of the vitellogenin was as follows: (ac)thr-pro-ala-leu/ala-asp-tyr. ... | 1996 | 8829806 |
| intestinal na+ and cl- levels control drinking behavior in the seawater-adapted eel anguilla japonica | to analyze drinking mechanisms in seawater teleosts, seawater-adapted eels were used as a model system. when the intestine of the eel was perfused with iso-osmotic mannitol, the eels drank sea water. however, when the perfusion medium was switched to iso-osmotic nacl, seawater drinking was depressed. this depression was observed even after blocking nacl absorption across the intestine by replacement of the perfusate with choline chloride or by treatment with furosemide, an inhibitor of nacl and ... | 1996 | 9318466 |
| morphogenesis of the brain in larval and juvenile japanese eels, anguilla japonica. | we compared the morphology, including relative volumes (rv), of some brain regions in leptocephalus larvae (10-30 mm in total length), glass eels (elvers), young, and immature pre-adults of the japanese eel anguilla japonica. the external brain shape of the leptocephali gradually changes from a laterally compressed one to a depressed elongated one. these changes are fundamentally due to biased growth of the telencephalon and optic tectum. the dramatic brain transformation progresses until the ju ... | 1996 | 8834783 |
| tocopherol levels in the plasma lipoproteins from japanese eel anguilla japonica. | the alpha- and gamma-tocopherol levels in the plasma of japanese eel (anguilla japonica) were 53.9 micrograms and 1.3 micrograms/ml of plasma, respectively. the alpha-tocopherol in the plasma was mainly distributed as very-low-density lipoprotein and low-density lipoprotein (ldl), while ldl and high-density lipoprotein constituted most of the gamma-tocopherol. a highly positive coefficient of correlation was observed between the alpha-tocopherol and lipoprotein contents in japanese eel plasma. | 1995 | 8611757 |
| spinal and parachordal neurons in the eel leptocephali, anguilla japonica revealed by labeling with a fluorescent dye. | the spinal and parachordal neurons innervating the trunk muscles and skin in the japanese eel leptocephali, anguilla japonica, were retrogradely labeled with a fluorescent dye, dii (1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate). the spinal motoneurons innervating the trunk muscles were located in the medioventral part of the spinal cord and were divided into two populations on the basis of their soma sizes and position. the sensory neurons were labeled in the well-developed ... | 1995 | 8584211 |
| the onset of spermatogenesis in fish. | under cultivation conditions, male japanese eels (anguilla japonica) have immature testes containing only spermatogonia together with inactive testicular somatic cells, leydig cells and sertoli cells. using a recently developed organ culture system for eel testes, we have shown that hormonal induction of spermatogenesis in eel testes involves gonadotropin stimulation of leydig cells to produce 11-ketotestosterone, a potent androgen in fish. in turn, 11-ketotestosterone activates sertoli cells to ... | 1994 | 7835154 |
| growth hormone (gh)-dependent hepatic gh receptors in the japanese eel, anguilla japonica: effects of hypophysectomy and gh injection. | control mechanisms of growth hormone (gh) receptors in the eel liver were examined by following the time course of changes in total (mgcl2-treated membranes) and free (untreated membranes) gh-binding sites after hypophysectomy and replacement therapy with homologous gh. both total and free binding sites decreased significantly 1 week after hypophysectomy. scatchard analysis indicated that the reduction in gh receptors was primarily due to a decrease in the number of binding sites, rather than to ... | 1992 | 1577242 |
| hormonal induction of all stages of spermatogenesis in vitro in the male japanese eel (anguilla japonica). | the importance of gonadotropins and androgens for spermatogenesis is generally accepted in vertebrates, but the role played by specific hormones has not been clarified. under cultivation conditions, male japanese eels (anguilla japonica) have immature testes containing only premitotic spermatogonia, type a and early-type b spermatogonia. in the present study, a recently developed organ-culture system for eel testes was used to determine in vitro effects of various steroid hormones on spermatogen ... | 1991 | 2062857 |
