In this study, diI (1, 1, dioctadecyl-3, 3, 3', 3'-tetramethyl-indocarbocyanine perchlorate) as a derivative of the carbocyanine dye, a fluorescent lipophilic substance, was applied in fixed tissue for tracing the neuronal connections of the deep layers of the tectum with some mesencephalic nuclei in pigeons (Columba livia). The results indicate that the deep layers (II h - III ) of the tectum receive their neuronal inputs from the nucleus isthmi pars magnocellularis (Imc), the nucleus nervi oculomotorii, pars ventralis (OMv) and the nucleus mesencephalicus lateralis, pars dorsalis (MLd). A comparative analysis has been earned out between the results of this study and those obtained with CB-HRP.

Degradation of indole by an indole degrading methanogenic consortium enriched from sewage sludge proceeded through a two step hydroxylation pathway yielding oxindole and isatin. The ability of this consortium to hydroxylate and subsequently degrade substituted indoles was investigated. Of the substituted indoles tested, the consortium was able to transform or degrade 3 methylindole and 3 indolyl acetate.

Degradation of indole by an indole degrading methanogenic consortium enriched from sewage sludge proceeded through a two step hydroxylation pathway yielding oxindole and isatin. The ability of this consortium to hydroxylate and subsequently degrade substituted indoles was investigated. Of the substituted indoles tested, the consortium was able to transform or degrade 3 methylindole and 3 indolyl acetate. Oxindole, 3 methyloxindole, and indoxyl were identified as degradation metabolites of indole, 3 methylindole, and 3 indolyl acetate, respectively. Isatin (indole 2, 3 dione) was produced as an intermediate when the consortium was amended with oxindole, which provided the evidence that degradation of indole proceeded through successive hydroxylation of the 2 and 3 positions prior to ring cleavage between the C 2 and C 3 atoms on the pyrrole ring of indole. The presence of a methyl group ( CH 3 ) at either the 1 or 2 position of indole inhibited the initial hydroxylation reaction. The substituted indole, 3 methylindole, was hydroxylated at the 2 position but not at the 3 position and could not be further metabolized through the oxindole isatin pathway. Indoxyl (indole 3 one), the deacetylated product of 3 indolyl acetate, was not hydroxylated at the 2 position and thus was not further metabolized by the consortium. When an H atom or electron donating group (i.e., CH 3 ) was present at the 3 position, hydroxylation proceeded at the 2 position, but the presence of electron withdrawing substituent groups (i.e., OH or COOH) at the 3 position inhibited hydroxylation.

The interaction beteen skatole and α-Amylase was studicd by ultraviolet spectroscopy and fluorescence spectrometry.The Stern-Volmer plots showed that the quenching of skatole to α-Amylase was probably a static quenching process.The combination constant KA(4.61×103)and the number of combination sites n(0.83) was educed by graphical chart of lg[(F0-F)/F]versus lg [Q].

利用利紫外差光谱、荧光光谱研究了3-甲基吲哚(粪臭素)与胰α-淀粉酶的相互作用。Stern2—Volmer淬灭曲线显示粪臭素对胰α-淀粉酶的荧光猝灭是静态猝灭。以lg[(F0-F)/F]对lg[Q]作线性拟合得出其结合常数KA=4.61×103(mol/L)-1,与结合位点数n=0.83。
