[High performance liquid chromatography identification of chloracetophenone in ocular tissues in burns induced by gas balloons (an experimental study)].

The kinetics of chloracetophenone (CN) in rabbit eyes was studied by high-performance liquid chromatography on a model of experimental third-degree burn. By the end of the first hour after exposure to the lacrimate, CN content was high in all the studied tissues: 28.5 +/- 0.563 x 10(-1) mg/kg in the cornea, 5.08 +/- 0.193 x 10(-1) mg/kg in the anterior chamber humor, and 3.26 +/- 0.123 x 10(-1) mg/kg in the vitreous. After 6 h the content of the irritant dropped almost threefold and was 8.5 +/- 0.403 x 10(-1) mg/kg in the cornea, 1.23 +/- 0.062 x 10(-1) mg/kg in the anterior chamber humor, and 0.017 +/- 0.006 x 10(-1) mg/kg in the vitreous. By the end of 24 h these values were 6.6 +/- 0.221, 1.46 +/- 0.123, and 0.015 +/- 0.005 x 10(-1) mg/kg, respectively, and by day 14 only trace amounts of CN were detected. Hence, CN in the Cheremukha gas balloons can penetrate into the inner structures of the eye and cause severe injuries. Persistence of CN for up to 14 days disordered the metabolic processes and anatomy of the eye. High content of CN during the first 7 days after burn requires adequate pathogenetic therapy.

[Experimental implantation of the "Ufalens" artificial lens in primary surgical treatment].

Described in the paper is the response of eye tissues in extraction of traumatic cataract with IOL implantation observed in primary surgical treatment of penetrating corneal wounds. Experiments were made on 60 rabbits (120 eyes). 5 mm-long penetrating corneal wounds located in the optic zone with damaged lens were modeled in the experimental group (30 rabbits, 60 eyes). The wound was surgically treated in 24 hours: traumatic cataract was extracted and posterior-chamber IOL was implanted ("Ufalens-1" manufactured at the UFA Research institute of eye diseases). Thirty rabbits (60 eyes) were in the control group: transparent lens was extracted in them and IOL (same model) was implanted. The animals were taken out of the experiment by air embolism on days 3 and 7 and in 1, 3 and 7 months. Tinting with hematoxylin or eosin was used to ensure plain histological examination. The stages of histological treatment of tissues were carried out according to the standard method. A conclusion was made on the basis of research results that the implantation of "Ufalens-1" in primary surgical treatment of eyeball wounds with damaged lens does not have any essential clinical or morphological impact on the severity of the postoperative period and can be recommended as a method of medical rehabilitation of victims for use at specialized ophthalmologic clinics.

[Diagnosis and treatment of children with acute inflammatory diseases of the orbit].

The role of computer tomography within the differential diagnosis of acute inflammatory lesions of orbit tissues as well as an appropriate tactics of treatment were evaluated. Computer tomography, "Somafom AR-T", 512 x 512 pix matrix, Siemens (Germany), was made in the axial and coronary projections to delineate the inflammatory zone. The findings of computer tomography denoted explicitly the spatial features of pathology within the orbit with anatomic structures. In periostitis and reactive edema in retrobulbar fat of the orbit, the treatment of patients was conservative made jointly with otolaryngologist. Orbitotomy with drainage or with lancing of affected sinuses was made in abscess and phlegmon of the orbit. There was a complete recovery in a majority of patients with acute diseases of the orbit; they preserved their functions of the organ of vision and of its appendages. Therefore, computer tomography is a valuable and highly effective examination tool within the differential diagnosis of acute inflammatory diseases of the orbit. The diagnosis and treatment of such diseases call for a board of doctors including ophthalmologist, otolaryngologist and oral surgeon.

[An experimental-clinical study of the effectiveness of kerakol in the treatment of corneal burns and mechanical injuries ].

Kerakol efficacy in experimental burn and mechanical injuries was studied. The drug was shown to stimulate repair processes in the cornea, promoting an earlier differentiation of epithelial cells and their layers. Corneal stroma repair manifested by an earlier maturation of collagen structures with their correct orientation. Clinical trials showed kerakol efficacy in the treatment of corneal burns and injuries.
