[Use of partly hydrolyzed and untreated straw meal in the feeding of breeding sows. 4. Influence on embryonic mortality and fertility]. / Untersuchungen zum Einsatz von teilhydrolysiertem und unbehandeltem Strohmehl in der Fütterung von Zuchtsauen. 4. Mitteilung. Einfluss auf die embryonale Mortalität und Fruchtbarkeitsleistung.

The influence of a supplement of variously treated straw materials to a ration to dry concentrate (= 1), (untreated = 2, steamed = 3, HCl-treated = 4 and partly hydrolysed = 5) during gestation on fertility and rearing performance, the embryonic survival quota of fertilized ova as well as on some selected metabolites in the blood serum was studied in 3 experiments. The integration of untreated straw meal resulted in significantly diminished performances in comparison to test groups 1 and 5 in all tested parameters of fertility and rearing performance (weight of litter). The best results were achieved in all experiments with rations of concentrate and partly hydrolysed straw meal. The individual test groups the following performance values (number of piglets born alive, weight of litter in kg) were achieved: 1 = 9.3, 12.3; 2 = 6.5, 8.2; 3 = 7.5, 9.6; 4 = 8.6, 12,4; 5 = 10.6, 14.4). Ration specific reactions could only be proved for the parameters glucose and urea out of the metabolites (insulin, glucose, cholesterol, urea tri-iodine thyronine and thyroxine).

[Effect of the propellants O2 and CO2 on the efficacy of oral irrigation]. / Einfluss der Treibgase O2 and CO2 auf die Effektivität der Mundduschbehandlung.

The therapeutical results obtained with oral irrigations when O2 or CO2 was used as a propellant air compared with those achieved with compressed air. The assessment of the therapeutical success was based on the periodontal disease index according to Kötzschke and the exsudate heights according to Egelberg. A significant improvement in the periodontal condition was stated in all three groups of patients. Though only the exsudate values for the O2 group were significantly better than those for the compressed air group, being the only difference between the groups which was significant, the greater efficiency of the O2 and CO2 application (compared to compressed air application) is, nevertheless, obvious and interpretable. The therapeutical results obtained permit the statement that a technically perfect device and the further increase of the partial pressure of O2 or CO2 in the irrigation fluid will lead to even better therapeutical results, for which purpose the suggestions given should be considered in establishing the indication. The favourable results achieved with compressed air testify to the beneficial action of each irrigation or spray treatment.

[The quantitative determination of gingival sulcus fluid by means of filter paper strips--an objective measure in the evaluation of success of periodontal treatment?]. / Die quantitative Bestimmung der gingivalen Sulkusflüssigkeit mittels Filterpapierstreifen--ein objektiver Massstab bei der Erfolgsbewertung der Parodontalbehandlung?

The success of various periodontal treatments can be demonstrated by the quantitative determination of the gingival sulcus fluid if these treatments improve the peripheral blood supply. Compared to the manual method of determining the diffusion height of the exudate prior and after periodontal therapy (the extent of exudate reduction being used as a criterion for the degree of regression of the inflammatory circulatory disorder), the photometric-planimetric techniques yield exacter and even more favourable results. Due to its easiness and rapidity, the measurement of the diffusion height of the exudate is, as an additional control examination, useful in assessing the success of periodontal treatment.
