The authors submit information on the contemporary state of epikeratophakia in the world. They mention its advantages, surgical technique and initial experimental results. They pay also attention to problems associated with its introduction into clinical practice in this country.
An experiment was conducted to verify the possibility to use the self-polymerizing metacrylate resin DURACRYL EXTRA, commonly used in dental prosthetics, for simple fixing of fractures in small animals. The metacrylate was placed in a very small distance from the bone and the generally available surgical materials were used to connect it with the bone fragments (Kirschner's wires and surgical wire). Tree types of diaphysial fractions of femur and humerus were evaluated in a group of rabbits, dogs and sheep. The histological study of the reaction of the adjacent soft and hard tissues to metacrylate in the stage of healing of fracture is documented by the normal course of the reparative processes with no signs of more serious non-adequate reaction. The method of using the resin is generally simple, inexpesive and has low requirements for the use of instruments. This promises broad use in practice in the treatment of other kinds of fractures, mainly in those cases where there is a lack of special equipment for the surgery of bones.
In this paper the haemocoagulative effect of the Vasolamin preparation was examined after intravenous application in cattle, sheep, and horses by means of tests. After a laboratory confirmation of the coagulative effect of the tested preparation we used it for the purpose of haemostasis in the clinical practice. After an administration of the preparation faster coagulation of the blood was observed in all examined animals. The setting in of the effect could be observed already after 5 minutes, the maximum effect was recorded between the 15th and 30th minutes after application, and the effect lasted, although gradually weakened, for one to two hours. In the case of bleeding clinical patients the application of Vasolamin was always successful.
