ISSN: 1438-2385Source: Springer Online Journal Archives 1860-2000Topics: Process Engineering, Biotechnology, Nutrition TechnologyDescription / Table of Contents: Summary Concentrated permeate (27% TS) was prepared by ultrafltration of skim milk and concentrated by reverse osmosis and vacuum evaporation. The whole strawberry fruit was homogenized and added to concentrated permeate at the rate of 1:3 and left to settle, and the clear supernatant liquid was separated. Artificial colour was added and the mixture was spray-dried. Cane sugar and citric acid were added to the powder at the rate of 25:1:25 and product was packed in polyethylene bags and stored in air-tight containers. The changes in the physical properties, chemical composition and vitamin contents of the powdered beverage were followed when fresh and after 3 and 6 months of storage. Also organoleptic properties of the powder formed were assessed by a taste panel of the reconstituted beverage (15% TS). The results obtained clearly indicate the possibility of producing an acceptable beverage based upon strawberry permeate blends in dried form.Notes: Zusammenfassung Konzentriertes Permeat mit 27% Trockensubstanz wurde durch Ultrafiltration aus Magermilch und durch Umkehrosmose und Vakuumverdampfung eingedickt. Die ganzen Erdbeerfrüchte wurden homogenisiert und zu dem Permeat-Konzentrat im Verhältnis 1:3 zugesetzt; Absatz und überstehende Flüssigkeit wurden beseitigt, künstlicher Farbstoff wurde zugesetzt und die Mischung sprühgetrocknet. Weiterhin wurde Rohzucker und Citronensäure zum Pulver im Verhältnis 25:1:25 zugesetzt und in Polyethylenbeutel verpackt und in lichtdichten Behältern gelagert. Die Veränderungen in den physikalischen Eigenschaften, in der chemischen Zusammensetzung und der Vitamingehalt wurden frisch und nach drei bzw. sechs Monaten Lagerung bestimmt. Ebenso wurden die sensorischen Eigenschaften des Pulvers in einem Getränk mit 15% Trockenmasse durch Prüfergruppen verfolgt. Die Ergebnisse zeigen klar auf, daß brauchbare Getränke mit Erdbeeren in Permeat-Mischungen in getrockneter Form herzustellen möglich sind.Type of Medium: Electronic ResourceURL: -
5Articles: DFG German National LicensesEffect of some central nervous system acting drugs on rat brain and liver monoamine oxidase activityStaff View
ISSN: 1420-908XSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract A number of central nervous system acting drugs were administered to male rats. At certain time intervals after the administration of these drugs, the rats were sacrificed. Liver and brain monoamine oxidase (MAO) activities were determined. The drugs employed were: ethyl alcohol, cognac, hexobarbital, diazepam, imipramine and chloralose. Results obtained indicated that the liver MAO activity was not altered by any of these drugs. Brain MAO activity, contrary to in vitro studies, was increased by alcohol and cognac. The increase was not due to a direct effect of alcohol on the enzyme activity, since the in vitro addition of equivalent concentrations of alcohol, as those calculated to be present in vivo, to brain homogenates resulted in a decrease rather than an increase in activity.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-1912Keywords: Schistosomiasis ; Tartar Emetic ; Lucanthone ; Niridazole ; MetabolismSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Summary Schistosomal infection in mice caused an inhibition of the hepatic drug metabolizing enzyme activities. The magnitude of inhibition was not the same for all enzyme activities measured. MMAA and paraoxon metabolizing activities were only moderately affected. Treatment of infected mice with schistosomicidal drugs produced a dramatic reversal of the inhibition in cases of MMAA and paraoxon metabolizing enzymes, the 2 activities mostly affected by schistosomal infection. On the other hand, the reversal of inhibition was not statistically significant in the other 2 enzyme activities. Comparing the effectiveness of the different schistosomicidal drugs in reversing the inhibition produced by schistosomal infection, lucanthone HCl was found to be inferior to the other drugs used, namely, tartar emetic, stibophen and niridazole.Type of Medium: Electronic ResourceURL: -

ISSN: 1612-4766Source: Springer Online Journal Archives 1860-2000Topics: BiologyAgriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Abstract The essential oils of four medicinal plants belonging to Lamiaceae were explored for phytonematode control. The four oils inhibited (P〈0.05) nematode motility butMentba spicata was generally more effective in reducing the numbers of active nematodes followed byThymus vulgaris, Majorana bortensis andMentba longifolia. The main corresponding compound of each oil, determined by GLC analysis, was carvone (58.14%), P-cymene (40.5%), terpinen-4-ol (41.6%) and carvone (70.36%). Soil stages of the reniform nematode were more affected by the oil than those of the ring and lance nematodes. When transferred to water, the total nematodes that regained their activeness ranged from 12% forT. vulgaris to 60% forM. longifolia. The four 0.1 oil solutions inhibited more than to about 3.5% at the control. The content of oxygenated compounds in these oils ranged from 45.79% to 96.5% and may be partially responsible for the nematicidal effects.Type of Medium: Electronic ResourceURL:
