Einfluß von oxidierten Ölen/Fetten sowie α-Tocopherol- und Antioxidantienzulagen auf das Wachstum und die Vitamin E- und A-Gehalte in Geweben von Masthühnerküken

Oxidized Oils/Fats and α-Tocopherol and Antioxidants Increase on Growth and Vitamine E and A Contents in the Tissue of Fat Pullet Chickens Fat contents in mixed food for fat pullet chickens lead to the assumption that the fat will be perished within a very short time whereby negative consequences for the fat soluble vitamines E and A must be expected, too. During three feeding tests with each at 20 groups of 9 animals in each group fresh and oxidized fat (lard, animal mixed fat) or oil (refined soya bean oil) was added to the feed basic mixture at an amount of 10%. Various α-tocopherolacetates (α-TA) increases (0, 25, 50, 75, 100 mg/kg feed) and various synthetic antioxidants (EMQ, BHT, LOXIDAN-TD 100) in combination with 25 or 50 mg α- TA were added to feed mixtures in 3 tests. The determinations of vitamin E and A in blood plasma, in the fat of the subdermal fatty tissue and of the liver took place by high pressure liquid chromatography. The vitamine A content in the livers decreased significantly by the oxidized fats/oils. If the ratios contained antioxidants in addition, statistically secured higher vitamine A data in this organ were found.     

Plasma arc systems for waste treatment and metal recovery

Plasma torches are being used for treating very difficult wastes,for recovering metal values from metallurgical wastes, and for making high-quality ingots and powder in the special metals industry. This article discusses the process requirements and the state of the art for plasma arc systems in each of these fields.     

Aneuploidy index in blood: a potential marker for early onset, androgen response, and metastasis in human prostate cancer

OBJECTIVES: To investigate whether the frequency of chromosome abnormalities in peripheral blood lymphocytes defined as the aneuploidy index in blood (AnIB) can be used as a clinical marker of early age onset, androgen response, and metastasis in human prostate cancer. METHODS: Peripheral blood samples were collected from 80 patients with prostate cancer, and chromosome preparations were made from 72-hour cultures after mitotic block. The AnIB of 59 informative cases was compared with several parameters, including age at disease onset, Gleason grade of tumor, clinical stage of tumor, metastasis, and prostate-specific antigen (PSA) level. RESULTS: Patients with AnIB levels greater than 3 had a significantly higher incidence of metastasis (P = 0.022), androgen-independent disease (P = 0.002), and early age at disease onset (age at diagnosis less than 65 years) (P = 0.002) compared with the patients with lower AnIB (less than 3) levels. In addition, patients with AnIB levels greater than 5 had higher PSA levels (greater than 20 ng/mL) (P = 0.029) than patients with AnIB levels less than 5. CONCLUSIONS: Chromosome abnormalities can be detected in the peripheral lymphocytes of patients with prostate cancer, and AnIB can be used as an early diagnostic and predictive marker for prostate cancer metastasis and androgen-independent disease.
