    Notes: [Auszug] Sodium and potassium analysis. These ions were determined by comparison against known concentrations in the Toner-Pitts flame photometer. This sensitive instrument balances a specific lithium ion concentration against the sodium or potassium ion, and the result is found photometrically through ...

    Notes: [Auszug] THERE have been no general investigations of the ascorbic acid levels in the tissues of guinea-pigs nor of their depletion on scorbutigenic diets since the comprehensive report of Penney and Zilva in 19461. Reports on the effects of several substances such as ACTH and insulin on ascorbic acid ...

    Notes: Ten placentae with massive subchorionic thrombohaematomas are reported. This lesion, which is composed of maternal clotted blood, separates the chorionic plate of the placenta from the villous chorion and is traversed by the main cotyledonary branches of the fetal circulation. In some instances it dissects into the layers of the chorionic plate. In anatomical terms it is identical to the lesion which has been described in early pregnancy under the title of Breus’ mole. Previous reports suggested that the lesion was confined to early pregnancies and was a consequence of fetal death. In our series all ten placentae were from pregnancies of at least 25 weeks' maturity and six were more than 30 weeks. Seven infants were liveborn and three survived the neonatal period. Differential diagnosis is discussed along with aetiology, which is still obscure although earlier theories implicating fetal death may be discounted.

    Notes: [Auszug] Following closure of the blastopore, the Fundulus embryo is essentially two compartments. The first is the yolk, which is entirely surrounded by the second, the embryo proper. This latter is not really homogeneous, for it consists of the syncytial peri-blast, in direct contact with the yolk, and ...
