    Notes: Seeds of six cultivars of white clover were sown in 1983 in slots in tares of permanent pasture in soil-filled tanks in spring and in small plots in the field during midsummer. The clover cultivars investigated were the large-leaved Olwin and Milk nova, the medium-leaved Grasslands Huia and Aberystwyth S100, and the small-leaved Kent Wild White and Aberystwyth S184. Seeds from an indigenous clover population were also sown in the tanks. All herbage was defoliated at three- to six-week intervals to simulate rotational grazing and assessments were made until autumn 1984.Leaf and stolon production and spread of stolons from the slots were more rapid in Milkanova, S184, Huia and Kent than in Olwen and S100 In the tanks, harvested yields of clover leaf and petiole were largest for Milkanova and Olwen and least for the indigenous population; both Olwen and S100 had a smaller percentage of their total weight outside the slot area than had the other varieties. In the field, Milkanova greatly out yielded all other varieties and S100 yielded the least, contributing 48 and 27%, resf actively, to total herbage yield. The yield of grass differed little between varieties in tanks but in the field it tended to be higher with the smaller than with the larger-leaved varieties. Total herbage yield was largest for Olwen and Milkanova in tanks and for Milkanova in the field. The greatest weight of stolons in tanks was produced by Olwen and in the field by Olwen and Kent, but the greatest length of stolons and number of nodes in both environments occurred in the smalt-leaved varieties, especially Kent. Least length of stolons and fewest nodes in the tanks were produced by Olwen and in the field by Milkanova.It was concluded that all the varieties investigated could be successfully slot-seeded into permanent pastures but that the choice of variety will depend on subsequent use and management of the resulting swards.

    Description / Table of Contents: Résumé Une série de 7 malades hyperparathyroïdiens qui présentaient des glandes parathyroïdiennes hyperfonctionnelles situées au sein de la thyroïde est présentée par les auteurs. Dans 7 cas sur 8, elles répondaient aux glandes parathyroïdiennes inférieures et ce fait est discuté en fonction de nos connaissances actuelles de l'embryologie. La présence d'une glande parathyroïdienne hyperfonctionnelle au sein de la thyroïde doit être envisagée en cas d'échec de la chirurgie parathyroïdienne. En fait quand une glande parathyroïde inférieure n'est pas retrouvée en cours d'intervention les auteurs recommandent d'inciser le pôle inférieur de la thyroïde et de pratiquer, si nécessaire, une lobectomie thyroïdienne.
    Abstract: Resumen La glándula paratiroides de ubicación anormal es una bien reconocida causa de fracaso en cirugía paratiroidea. Una de las anomalías más interesantes y provocadoras es la paratiroides hiperfuncionante intratiroidea. Se define la paratiroides intratiroidea como la glándula paratiroides, normal o anormal, que se encuentra totalmente ubicada en el interior de la tiroides y rodeada por parenquima tiroideo. Se presentan las características clínicas, quirúrgicas, y patológicas de 7 pacientes con hiperparatiroidismo, en quienes 8 glándulas paratiroides intratiroideas fueron halladas. Estos 7 casos representan 3.5% de 200 pacientes sometidos a exploración cervical por hiperparatiroidismo entre 1978 y 1984. Siete de las 8 glándulas fueron paratiroides inferiores, hallazgo que es discutido a la luz de conocimientos embriológicos actuales. La paratiroides hiperfuncionante intratiroidea no es una anomalía rara y es considerada como una potencial causa de fracaso en cirugía de paratiroides; por consiguiente, cuando en el curso de la exploración no se encuentre una de las paratiroides inferiores se debe incidir el polo inferior de la tiroides y, si necesario, realizar lobectomía.
    Notes: Abstract The details of 7 patients with hyperparathyroidism in whom 8 intrathyroid hyperfunctioning parathyroid glands were located are presented. Seven of the 8 glands were inferior parathyroids and this observation is discussed in the light of current embryological teaching. The intrathyroidal hyperfunctioning parathyroid is considered to be a potential cause of failed parathyroid surgery and, therefore, when an inferior parathyroid gland is missing, it is recommended that the lower pole of the thyroid be incised and, if necessary, a thyroid lobectomy performed.

    Notes: [Auszug] The cellular ageing process has been attributed to the accumulation of errors in cell control mechanisms with time, although the level at which significant errors occur and the type of error involved are subjects of speculation1'2. The possibility that ageing is associated with epigenetic errors ...
