Traumatic extraction of permanent teeth (avulsion completa) is a serious teeth injury with uncertain outcome and it requires dentist's on duty fast and adequate reaction. In this study a complete therapy plan for eleven year old girl, who came to the Clinic because of avulsed teeth 11, third class fracture of tooth 12 and second class fracture of tooth 21, was showed. After clinical examination and upper frontal region X-ray, we started with replantation of the tooth 11, as well as with wirecomposite splint placement. After successfully done replantation and injured teeth endodontic treatment, prosthetic sanation of the patient was done. In this study, clinical picture of the patient one year after the injury was also showed.

Periodontal disease is a chronic inflammatory disease that is largely attributable to infections with gram-negative bacteria and is characterised by both gingival inflammation and alveolar bone resorption. Beside macrophages, the second most common cells of the gingival inflammatory infiltrat are mast cells. Mast cells are heterogenous cell population which live from six months to one year. These cells are activated by differnt immunologic and non-immunologic signals. Activated mast cells can secrete a range of substances that regulate angiogenesis, tissue remodeling and wound healing, which include both degradation and synthesis of tissue components. Apart from that, mast cells have an important role in phagocytosis, antigen processing and presentation to T-cells. It is confirmed that gingival mast cells can express matrix metalloproteinases (MMPs) and the tissue inhibitors of metalloproteinases, TIMP-1 and TIMP-2. This indicates that mast cells are likely to play an important role in inflammation and tissue degradation in periodontal diseases.

Allergen-specific immunotherapy (SIT) is the practice of administering gradually increasing quantities of an allergen extractto an allergic subject to ameliorate the symptoms associated with the subsequent exposure to the causative allergen. The major objectives of SIT in alergy disorders are, in the short term, to reduce the allergic triggers precipitating symptoms, and, in the long term, to decrease allergy inflammation and nonspecific bronchial hyperreactivity when bronchial remodeling is not prominent. The mechanisms of SIT are complex but it was convincingly shown to act by modifying Th2 cell responses either by immune deviation (increase in Th0/Th1) or T cell anergy (decrease inTh2/Th0) or more likely both. Specific immunotherapy is the only treatment that may alterthe natural course of allergic disease.

In this work we present a basic aspects of ionising radiation (afterward of depleted uranium), this effects to human organism, esspecially on radiobiological, health effects on human skin. Health effects ionising radiation on skin depends of its doses. High doses given stron reaction, already in a few days after radiation, and later manifestations arise after longer exposition lower doses this radiation. In this work we present a basics pathophysiological aspects, without specifical clinical manifestations of radiation dermatitis.

Eosinophilic Granuloma (EG) represent the most benign and localized form of the three Langerhans cell histiocytosis syndromes. In bone, it is a tumor-like proliferation Langerhans cells. Intraosseous EG lesions can be solitary or multifocal. EG accounts for 60-70 % of Langerhans cells histiocytosis cases. The authors are describle a 21 year-old men with Eosinophilic granuloma. The disease had a rarely course with disorders multiple lesions in bones

Sjögren'ssyndrom is autoimmune disorder where cells of immune system afack and destroy eccrine glands which produce tears and spit. We have a patients with following problems: dryness of the bucal lining and conjunctiva, dysphagia of solid food, paint in joints amd muscles, hand sensitivity to coldness.

The biggest Serbian medival hospital had founded Stefan Urosh III Nemanjich in the monastery named Dechani. In 1340, it had been founded the hospital of the emperors Dushan in monastery of St.Arhangel near tawn Prizren. By liberation of the province Kosovo and Metohija from the Turkish rule and by united with Serbia,the health had been diveloping in this region. In 1922, it had been founded the state hospital in 1931. Governor, and in 1938, this hospital had the 120 beds and three laboratory rooms for analyses of blood and of urine. In 1924, it had been formed the first bacterologist station in Prizren. In 1928, it had been formed the State childrens home which is in 1929. had been become public health station with the general school ambulanta first aid station,bathroom and laboratory. In 1927. it had been working the Polyclinic in Prishtina were theyhad been carrying on the laboratory analyses.In these health resorts in the province of Kosovo and Metohija have been carrying on the analyses of blood, urine and of bowel as and the microscopy of preparation to malaria and it has been carrying on the education of skilled workers for these analyses. After the Second World war it had been carrying on the education of laboratory technians it the courses and by opening of laboratories in hospitals and health stations in Kosovo and Metohija the specialization of medicine biochemistry have been ending a lot of pharmacists who give a famous contribution to the development of biochemistry in this territory.

Transition of xenobiotics from blood into brain tissue is limited by the blood-brain barrier (BBB), a very selective functional barrier that excludes penetration of various substances, while allowing essential nutrients to enter into CNS. Transport of drugs through the intact BBB depends of their physico-chemical characteristics, the way of drug application and of anatomical and functional integrity of the barrier. The aim of this work was to examine penetration of quinine and lysinacetylsalicilate in vivo through the rat BBB, after the intraarterial injection via the a. axillaris in the course to CNS. The
experiment was done on anaesthetized Wistar rats, body weight 200-300 g. Test animals received injection of quinine (25 mg/kg) or LAS (90 mg/kg). Blood from the left jugular vein and brain samples (brain stem, cerebellum, right and left cerebral hemispheres) were taken in four minutes period. Quinine concentrations in rat brain were higher than in blood (ratio between blood/brain concentration was <1) while LAS concentrations in blood were permanently higher, according to their liposolubility. Maximal concentration in the brain tissue of both drugs are time dependent which indicated the useness of an active transport

Glucagon is polypeptide hormone derived from pancreas which in addition to its metabolic actions has also certain cardiovascular stimulatory effects. We've explored the effects of glucagon on hemodynamic variables (mean arterial pressure, heart rate and central venous pressure) and on catecholamine level and the electrolite level in the kanine sera. It was estimated that glucagon expressed the positive chronotropic effect and significantly lowers the central venous pressure while inconsiderably inceases mean arterial blood pressure. It also leads to transient (short-lasting) hipokaliemia and nonsignificant hipocalcemia. As the result of the action of the glucagone, the serum adrenaline concentrations were significantly increased while the serum noradrenaline concentratios were significantly decreased

Ocular changes at the patients on dialysis are numerous but unique,too. They are caused by primary end-stage renal disease, influence of dialysing itself and regular co-morbid condition. Purpose of this study is to indicate specific ocular finding among patients who are on dialysis. This prospective study assessed 81 patients on regular, chronic dialysis. They underwent complete ophthalmologic examination. The most common findings were the following: conjunctival calcification (53 eyes), cataract (43 eyes) and retinal microangio-pathies(atherosclerotic, hypertensive and occlusive-in total 168 eyes). All findings mentioned above were statistically significant (p<0. 001) regarding to normal population. Ophthalmologist must be familiar with those abnormalities what is necessary for pointing out on special systemic co-morbid condition at the patients on dialysis.
