    Preliminary observations on nitrogen transport during summer in a small spring-fed Ontario stream (1976)

    Notes: Abstract Nitrogen transport in a 2 km-long, spring-fed stream was studied during the summer months by analyzing weekly water samples from four stations. The water at the spring had a consistently high level of nitrate-N ranging from about 7 mg/l in late spring to about 3 mg/l in early fall. However, over the length of the stream, 60% (about 97 kg) of the incoming nitrate-N is lost from the water during the summer period. The loss, which does not appear to be attributable to the uptake by aquatic macrophytes or to immobilization, is thought to result from denitrification.

    Immunocytochemical localisation of prolactin and growth hormone in the perinatal sheep pituitary (1979)
    Springer
    Cell & tissue research 197 (1979), S. 501-514 
    Details
    ISSN: 1432-0878
    Keywords: Prolactin cells ; Growth hormone cells ; Secretory granules ; Size range (quantitative analysis) ; Perinatal sheep pituitary

    Topics: Biology , Medicine
    Notes: Summary The peroxidase anti-peroxidase immunocytochemical staining technique has been used to identify prolactin and growth hormone cells in pituitaries from fetal and neonatal sheep. The size of the secretory granules in these cell types has been measured using the image analysing computer Quantimet 720. The area size distributions of the fetal prolactin and growth hormone granules were compared with those in the neonate and the adult. It appears that the gestational age of the fetus may influence the size range of prolactin secretory granules.
