[Behavioral response of cows after intrauterine application of disinfectants for treatment of endometritis]. / Das Verhalten von Kühen nach intrauteriner Applikation von Desinfizienzien zur Behandlung der Endometritis.

Seventy-five animals were investigated in an attempt to study the chronological process of response to vaginal irritation by application of disinfectants for endometritis therapy. Aqueous peracetic acid solutions and Lugol solution were used. Cows reacted to intrauterine application of disinfectant drugs with tail lifting, pressing and sometimes groaning as expression of pain. We tried to quantify this response by registration of these different signs longer than two hours after treatment. The responses are caused by reflux of solution from the uterus into the vagina. They were different and depending on reflux volume, used drugs and their concentration. In comparison to peracetic acid solutions, the application of Lugol with 0.5% iodine seemed to induce a more intensive response to application.

[Experimental studies of the effect of peracetic acid on the endometrium of cattle]. / Experimentelle Untersuchungen zur Wirkung der Peressigsäure auf das Endometrium des Rindes.

Histological investigations were made on uteri of 61 cattle (27 of them after intrauterine treatment). The response activated by 0.2% peracetic acid in the bovine endometrium was a primary inflammatory process, however, necrotising within clearly pronounced limits. Degenerative alterations were the major histological findings 35 minutes from application of 0.2% peracetic acid. They were recordable from the epithelium but at that point in time could easily affect the entire cellular stratum. Histopathological phenomena on the fourth day from application of 0.2% peracetic acid were clearly less strongly pronounced than on the third day. Histiocyte infiltrates of moderate and rarely high intensity reflected increased phagocytosis in the process of endometrial regeneration.

[Experiences in diagnosis and therapy of puppy diseases in the fist days of life]. / Erfahrungen in der Diagnostik und Therapie von Welpenerkrankungen in den ersten Lebenstagen.

In a survey covering 145 puppies in 60 litters diseases after parturition and within the first week of life are discussed. Problems in the diagnosis and therapy are correlated with further investigations, i.e. bacteriology, sensitivity tests and in some cases necropsy. Neonatal respiratory distress syndrome and bacterial infections have been found to be the most common diseases in the first days of life in puppies.
