Use of Antibiotics in Companion Animals from 133 German Practices from 2018 to 2023.

: While antibiotic usage in farm animals has been systematically monitored and reduced in many countries, including Germany, data on companion animals such as dogs and cats remain scarce. To address this gap, a study was conducted in Germany to analyze patterns of antibiotic use in dogs and cats. : Antibiotic usage data were obtained from debevet, a cloud-based veterinary practice management software based in Berlin, Germany.

[Alveolar adenoma of the lung. Immunohistochemical characterization of type II pneumocytes].

The alveolar adenoma of the lung is a rare benign tumor in which the normal parenchymal architecture is imitated by a proliferation of both the alveolar epithelial cells and the mesenchymal septal cells. The first description, based on six cases, was published in 1986 by Yousem and Hochholzer. From their ultrastructural findings they presumed a type II pneumocytes differentiation of the epithelial cells.

Nitric oxide production by cells isolated from regenerating rat liver.

Nitric oxide (NO) production by cells of the regenerating liver was estimated from the amount of nitrite accumulated during 24 h in the culture media of hepatocytes, Kupffer cells and sinusoidal endothelial cells isolated at different times after partial hepatectomy (PHE). The time course of NO production was compared with the course of the proliferating activity of the same cells. During the time when liver cells pass through their first cell cycles, hepatocytes were the main producers of NO in the liver.
