    Notes: Summary The development of substance P-like immunoreactivity (SPLI) in the goldfish brain was studied by means of the indirect peroxidase-antiperoxidase technique and an antibody to substance P. By 80 h after fertilization, the first SPLI-cell bodies appear in the ventricular zone of the future diencephalon and the first SPLI-fibers appear in the olfactory bulbs. Two days after hatching (which occurs at 100 h after fertilization), SPLI fibers connecting the olfactory bulbs and hypothalamus are seen. In the optic tectum SPLI-fibers appear for the first time 5 days after hatching. In the brain stem, SPLI-cell bodies appear in juvenile animals 40 days after hatching. The highest number and intensity of SPLI-cell bodies and fibers are found in the area postrema. SPLI-cell bodies are also seen in the gustatory nucleus, nucleus ambiguus, reticular formation of the medulla, dorsal motor nucleus of the vagus and commissural nucleus of Cajal. The significant information gained from the present study is: 1. The rostro-caudal sequence in which the SPLI appears in the developing nuclei of the goldfish brain 2. The reduction of SPLI-cell bodies in some nuclei with age Thus, in the brain stem, SPLI-cell bodies that were labeled in juvenile goldfish were not seen in adults. This might be due to changes in the rate of axonal transport, changes of the SP phenotype during development or cell death. The developmental sequence and relative timing in which SPLI-cell bodies appear in the goldfish, rat and mice are similar.

    Excess enthalpies of mixing tetrahydrofuran and tetrahydropyran with some chloroalkanes at 26.9°C (1993)

    Notes: Abstract Excess enthalpies of mixing H m E of tetrahydrofuran and tetrahydropyran with trichloromethane, tetrachloromethane, 1,2-dichloroethane, 1,1,2-trichloroethane and 1,1,2,2-tetrachloroethane have been determined at 26.9°C and are found to be negative over the entire composition range for both sets of the ether mixtures. H m E decreases in the sequence; dichloroethane 〉 tetrachloromethane 〉 trichloroethane 〉 trichloromethane 〉 tetrachloroethane. The results are explained on the basis of strong O...H-C and weak Cl...O specific interactions. Flory's theory has been used to correlate the experimental data with good agreement found between the theoretical and experimental values of H m E .

    Excess molar volumes of methyl tert-butyl ether with chloroalkanes at 30°C (1992)

    Notes: Abstract Excess molar volumes are reported for binary mixtures of methyl tert-butyl ether with trichloromethane, tetrachloromethane, 1,2-dichloroethane, 1,1,2-trichloroethane, 1,1,2,2-tetrachloroethane, or 1,1,1,2,2-pentachloroethane at 30°C over the entire composition range of the mixtures. Excess volumes for all the mixtures are found to be negative. A qualitative interpretation of the results in terms of O−H−C and Cl−O interactions is presented. The Prigogine-Flory-Patterson theory has been used to analyze the results.

    Excess enthalpies of di-n-butyl ether and methyl-tert-butyl ether with chloroalkanes at 26.9°C (1995)

    Notes: Abstract Excess enthalpies of di-n-butyl ether and methyl-tert-butyl ether with trichloromethane, tetrachloromethane, 1,2-dichloroethane, 1,1,2-trichloroethane and 1,1,2,2-tetrachloroethane have been determined at 26.9°C. Excess enthalpies H m E for all (except di-n-butyl ether + dichloroethane and + trichloroethane) of the binary mixtures are found to be negative. Enthalpies are generally more negative for mixtures containing methyl-tert-buthyl ether. The results have been compared with our earlier data on tetrahydrofuran and tetrahydropyran with chloroalkanes.
