    Notes: SYNOPSIS. Of several methods developed for cryopreservation of Trypanosoma vivax, Trypanosoma congolense, and Trypanosoma brucei metacyclic forms in tsetse fly organs, as well as bloodstream forms in host blood, one proved the most satisfactory. In this method, infected fly proboscises and salivary glands were placed in glass capillary tubes containing fetal calf serum with 8% (v/v) glycerol as the cryoprotectant. The method for bloodstream forms involved the addition of glycerol directly to infected blood, which was then dispensed into capillary tubes. Next the tubes were placed in paper containers inside a glass test tube with a 5 mm thick plasticine jacket. The insulated assembly was suspended in the liquid nitrogen vapor phase in an LR-35 (Union Carbide) refrigerator for 45 min. Under these conditions, the cooling rate was 2 C/min. The frozen samples were transferred to permanent storage. The viability and infectivity of the preserved organisms were found to be satisfactory upon testing, and no antigenic changes were observed. Laboratory and field applications of the method are discussed.

    Description / Table of Contents: Résumé L'association du seul tamoxifen à la mastectomie pour traiter le cancer du sein décelé à un stade précoce a donné lieu à un essai controlé randomisé. Les résultats du traitement à 2 ans ont été publiés en 1983. Ceux qui ont été constatés après une survie de 6 ans font l'objet de ce rapport qui concerne 1285 malades âgées de moins de 75 ans. Les malades traitées avant la période qui précède la ménopause et qui présentaient un envahissement ganglionnaire de l'aisselle et celles traitées après la ménopause qui présentaient ou non une atteinte des ganglions ont été réparties au hasard en deux groupes. Les patientes du premier ensemble ont reçu 10 mg de tamoxifen 2 fois par jour pendant 2 ans, celles du second ont été soumises au traitement classique jusqu'au moment ou une récidive se manifestait. Quarante-six pour cent des malades incluses dans cet essai ont bénéficié du dosage du contenu récepteur oestrogénique de la tumeur (ER). L'essai a permis de constater une réduction hautement significative du taux de la mortalité concernant le groupe traité, 45 malades (34%) ayant échappé à la mort, par rapport au groupe de contrôle. Ces résultats paraissent indépendants de la ménopause, de l'état des ganglions et de la teneur en récepteur oestrogénique.
    Abstract: Resumen Un estudio prospectivo y al azar con tamoxifen como agente adyuvante único en cáncer mamario temprano, el cual fue informado en 1983, cuando el período de seguimiento era apenas de un promedio de casi 2 años, ha sido seguido ahora hasta un máximo de 6 años. Mil doscientos ochenta y cinco pacientes con edades de 75 años o menos fueron incorporadas al ensayo clínico. Mujeres premenopáusicas con ganglios axilares positivos y mujeres postmenopáusicas con ganglios tanto positivos como negativos fueron adjudicadas al azar para recibir tamoxifen 10 mg dos veces al día por 2 años, o al grupo control libre de tratamiento sistémico, el cual sólo fue administrado en el momento de un relapso. El 46% de las pacientes tuvieron determinaciones del contenido de receptores de estrógeno en los especímenes del tumor primario. Se observa un incremento en el período libre de enfermedad y una reducción altamente significativa en la tasa de mortalidad, con 45 muertes menos (34%) en el grupo que recibió tratamiento que en el grupo control. Tal beneficio parece ser independiente del estado menopáusico, del estado ganglionar o de los receptores de estrógeno.
    Notes: Abstract A randomized controlled trial of tamoxifen as a single adjuvant agent after mastectomy for early breast cancer, reported on at an average follow-up of almost 2 years in 1983, has now been followed up to a maximum of 6 years. One thousand two hundred eighty five patients aged 75 or less were entered into the trial. Premenopausal women with positive axillary nodes and postmenopausal women with both positive and negative axillary nodes were randomized to receive either tamoxifen 10 mg twice daily for 2 years or to the untreated control group with systemic therapy reserved until the time of relapse. Forty-six percent of the trial population had primary tumor specimens assayed for estrogen receptor (ER) content. There has been a highly significant reduction in death rate, with 45 (34%) fewer deaths observed in the treated group than in the control group. This benefit appeared to be independent of menopausal, nodal, or ER status.

    Notes: Abstract The polychlorinated biphenyl Aroclor® 1254 was released in an accidental leakage of heat-exchange fluid from an industrial plant, into the Escambia River, near Pensacola, Florida, USA. This material was carried downstream, and is now found in the fauna of Escambia Bay and its contiguous waters, prime nursery areas for fishes and invertebrates such as penaeid shrimp. The significance of pollution by this chemical was assessed by establishing toxicity levels, determining routes of entry, and investigating its movement and distribution in various tissues of shrimp under controlled conditions in the laboratory. Aroclor 1254 added to the water was toxic to the juvenile pink shrimp Penaeus duorarum at a concentration of 1.0 part per billion within 15 days, but was less

    Notes: If a paraboloid of revolution capable of reflecting monochromatic X-rays over its whole surface could be constructed it would have applications as a monochromator producing a parallel beam of considerable cross-section from a point source.

    Notes: The diffraction profile and its moments are obtained for particle-size broadening, the expressions being `exact' in the kinematic approximation for crystals of simple shapes (parallelepiped, tetrahedron, octahedron, sphere). A further term in the variance-range curve is obtained, depending on Mitra's parameter 34, for which the name `rotundity parameter' is proposed. The effect of a distribution of particle sizes is discussed; the Scherrer constant and the taper parameter are affected in a way already known, and M is unaffected.
