Volatile constituents of the scent gland reservoir ofAspavia acuminata

Summary Volatile components of the scent gland complex of the adult bug ofAspavia acuminata, an agricultural pest from Nigeria, have been identified by the technique of combined gas chromatograph-mass spectrometry. Of specific interest is the presence in the gland reservoir of hex-2-enal, 4-oxo-hex-2-enal and 4-oxo-oct-2-enal.The author is grateful to the Bayero University Research and Higher Degrees Committee for financial support, Dr B. W. Staddon for his valuable assistance, Dr D. E. Games for arranging mass spectral facilities.

Comparison of the time courses of luteinizing hormone (LH) secretion rates during continuous stimulation by LH-releasing hormone (LH-RH) in vivo and in vitro

The patterns of LH secretion during constant stimulation of the pituitary glands of estradiol-treated ovariectomized rats with a maximally stimulating amount of LH-RH in vivo and in vitro correspond with each other qualitatively and quantitatively. In vitro the changes with time of the LH secretion rate are somewhat retarded, especially the occurrence of desensitization.
