    Notizen: The pathogenicity of Acremonium cucurbitacearum to 31 cucurbits, 18 crop plant species, and 15 weed species was evaluated under greenhouse conditions. This study demonstrates that many other cucurbits in addition to muskmelon and watermelon can potentially serve as hosts of A. cucurbitacearum. Using a disease severity index (DSI), all muskmelon and watermelon cultivars were ranked as susceptible or highly susceptible, with the exception of honeydew cultivar TAM Dew Improved, which ranked resistant in one study. Highly resistant cucurbits included Cucurbita maxima (autumn squash), Luffa acutangula, L. aegyptiaca (sponge gourd) and Benincasa hispida (ash gourd). Cyclanthera pedata and Cucumis miriocarpus were rated as resistant. The percentage recovery of A. cucurbitacearum ranged from 8% to 100% and tended to be higher in plants with a higher DSI. Other crops and weed species common to muskmelon production fields are not likely to be involved in the perpetuation or propagation of the fungus.

    Notizen: Summary Changes in α-amylase (α-1,4-glucan-4-glucanohydrolase, EC 3.2.1.1) of parotid gland were investigated during postnatal development of the rat. Modifications in amylase activity after birth allow the distinction of three stages which can be correlated with the morphologic development of the parotid gland. Significant sexual differences in the evolution of α-amylase activity were found. During the first stage (from birth to the 20th day) there is a higher increase in females, while males have a more pronounced increment in the second stage (from the 20th to the 30th day). By means of gel electrophoresis of parotid extracts, four molecular forms of amylase can be separated. The slowest migrating band (Form 1) is not detected at the initial stage.

    Notizen: Abstract. A case of unusual longevity to the age of 58 years is reported for a female patient with complete transposition of the great arteries. The association with a wide atrial septal defect with intact interventricular septum may have contributed to the long survival without surgery. Factors determining intercirculatory mixing and systemic oxygen saturation may be the high pulmonary flow, the location of the anatomic communication, sufficient hemoglobin concentration to allow an adequate level of systemic resistance and recirculated systemic flow, and the belated development of pulmonary vascular disease.

    Notizen: Summary The effect of gonadectomy (at the 10th day of life) and treatment with sexual steroids (during the first month) upon development of alpha-amylase activity in rat parotid gland has been studied. Alpha-amylase specific activity of parotid glands from 20-day-old orchidectomized rats and from 25-day-old ovariectomized animals was significantly higher than that of intact male and female rats of the same age respectively. Spayed males treated with testosterone (10 μg/day on the 13th, 15th, and 17th day) and ovariectomized rats treated with oestradiol (2.5 μg/day from the 16th to the 22nd day) showed values of enzymic activity similar to those of normal animals. Results indicate that oestradiol and testosterone have an inhibitory effect upon the increase of alpha-amylase activity in parotid gland during a very defined period of development.

    Notizen: Abstract Analysis of scientific production is made in the domains of vaccines for the period 1990–1995, including eight Iberian-American countries. To attain the results, different indicators were applied such as: collaboration rate, activity index and representation techniques, using a cluster analysis and multidimensional scaling. Similarities between countries are represented according to their activity index in the subject field. Results show a discontinuity in the scientific production over the years, where each country has a peculiar behavior.
