In the process for preparing an intravaginal application system for the controlled release of substances, a milled sheet of silicone rubber containing the substances is inserted into one mold component of a split mold. The core of the system is arranged on this milled sheet and is covered with a second milled sheet of the same type. The mold is then closed and the milled sheets are vulcanized at a maximum temperature of 120.degree. C.

Process for preparing an intravaginal application system

Nose-clip for the prophylactic or therapeutic treatment of cattle, which comprises a bow whose ends are suitable for receiving active ingredients in the form of depot bodies, the receiving ends being either inclined towards each other and turned to face each other or the surfaces of the depot bodies being inclined towards each other and turned to face each other. The depot bodies may be divided into dimensionally stable, optionally elastic, applicators free from active ingredient, and dimensionally variable reservoirs containing the active ingredients, said reservoirs being connected with said applicators. The receiving ends and/or depot bodies may form an angle with the longitudinal axes of the ends of the bow.

Device for the prophylactic or therapeutic treatment of cattle

Depot body on the basis of silicone rubber for the protracting release of active ingredients which contains from 2 to 50 weight %, relative to silicone rubber, of a release-promoting substance or a corresponding substance mixture in dissolved form, and a process for the preparation of such depot bodies. These depot bodies are suitable especially for the application of active substance onto the mucous membrane of the nasal vestibule of cattle.

Depot body on the basis of silicone rubber and process for the

High-dosage, orally administrable antibiotic preparations containing an antibiotic agent of the cephalosporin type and 5 to 15 % of a mixture of auxiliary agents, and process for preparing them.
