ANTIOXIDANT ROLE OF ASCORBIC ACID IN OXIDATIVE STRESS INDUCED BY STERENOUS EXERCISE
Strenuous exercises greatly increase oxygen consumption in the whole body, especially in skeletal muscles. Large part of oxygen consumption is reduced to H2O and ATP, but smaller part (2-5%) results in an increased leakage of electrons from the mitochondrial respiratory chain, forming various reactive oxygen species-ROS (02, H2O,iOH). These free ra- dicals are capable of triggering a chain of damaging biochemical and physiological reactions (oxidative stress, lipid peroxi- dation), as a base for skeletal muscles damage after exercise. MDA (malondialdehyde) is a marker of exercise induced lipid peroxidation process. L-ascorbic acid is a major aqueous-phase antioxidant. To estimate antioxidant role of ascorbic acid we use rate between dehydroascorbate and ascorbate. In this paper those markers of lipid peroxidation (MDA, MDA ind, % ind MDA), and ascorbic acid status (ascorbic acid Asc, ascorbat A, dehidroascorbat DHA, DHA/A) were determinated in 30 stu- dents, in rest and after treadmill running protocol (Bruce Treadmill Protocol). It was found that after the treadmill test, plas- ma MDA level had increased from 3,04 to 4,39 M/L (p<0,0001) and % ind MDA decreased significantly from 35% to 24,7% (p=0,0003). Plasma ascorbic acid was also found to be higher after the treadmill test comparing to rest level (from 55,4 to 67,6 μM/L). DHA/A level in rest was 1,62 and after treadmill test it increased to 2,05 (p=0,0014). These results suggests that strenuous exercise increased process of lipid peroxidation (MDA †, % ind MDA), but in the same time incre- ased ascorbic acid level in plasma and DHA/A rate indicates stronger activation of nonenzymatic antioxidant defense system.

MUTUAL RELATION CHRONICAL COMPLICATION OF DIABETES MELLITUS TYPE 2 IN THE SCOPE OF TESTED GROUP
Diabetes mellitus with its own chronical complication is the cause of the large procent morbidity and mortality between population. World Health Organisation (WHO) has announced that so far involved 150 millions peoples, so the prevention chronical complication this illnesses priority. By this work, I want to rescript signification connection microangiopathy chronical complication with macroangiopathy chronical complication of diabetes mellitus. Handled 60 patients with diabetes mellitus type 2. Patients divide in IV groups forms on concentration HbA1c. Retinopathy most often microangiopathy chronical complication of diabetes, in the meaning of being united with other complication, most expressed are the connection some with microangiopathy complication: angiopathy (R=0.71; p<0.001), then nephropathy (R=0.60; p<0.001) and the end neuropathy (R=0.44; p<0.001).

EFFECT OF ACUTE POISONING WITH ORGANOPHOSPHATE COMPOUNDS ON HYDROELECTROLITIC AND ACIDE-BASE STATUS OF CHILDREN'S
Acute organophosphate (ÎÐ) poisoning is an important cause of morbidity and mortality in children especially in the developing countries. Published studies work have been reported on acute childhood poisoning has focused mainly on the epidemiological trends, with little information about alteration in electrolitic and acid-base equilibrium and other disturbance and on the management of the poisoned children. Hypovolaemia, electrolyte derangements and acidosis are major predisposing factors for development of complications. Metabolic acidosis is one of the major causes of death in patients poisoned with OPC acutely. We suggest that children's with acute OPC poisoning should be screened for electrolyte and metabolic acidosis with blood gas analysis.

CEPHALOSPORINS AND NEPHROTOXICITY
Cephalosporins are bactericidal antibiotics that are active against a wide variety of Gram(+) and Gram(-) aerobic bacteria, along with a few anaerobic species. Adverse effects of cephalosporins are uncommon and reversible. Cefalotin and cefaloridine exhibit a nephrotoxic effect and might cause renal tubule necrosis. No data about the nephrotoxicity of cefotaxime and ceftriaxone has been presented in literature so far. When cephalosporins are applied via intramuscular injection a local reaction is possible, whereas with IV administration thrombophlebitis develops in about 5% of all cases. Hypersensitivity reactions, as well as some hematological disorders (thrombocytosis, leukopenia, neutropenia) might also occur. Cephalosporins were found to sometimes cause an augmentation of transaminase (AST, ALT), alkaline phosphatase, and, less frequently, bilirubin levels, too. The goal of this study was to evaluate the creatinine values in the serum of patients hospitalised in Kosovska Mitrovica Health Centre. The values were determined before, within and after 7 days of cephalosporin administration (cefotaxime 2x1000mg IM; ceftriaxone 2x1000mg IV). Data concerning certain hematological and biochemical variables will be presented as well. Creatinine levels were measured by the Jaffe reaction method. Both cefotaxime and ceftriaxone yielded a statistically significant increase of the serum creatinine values. As these cephalosporins do not show a nephrotoxic effect, the increase can be explained by the interference of sodium picramate, a byproduct of the Jaffe reaction which is produced regardless of whether the process is manual or automated.

THE IDENTIFICATION OF MORPHOLOGICAL CHARACTERISTICS RELATED WITH HORIZONTAL BODY AXES OF HANDBALL AND FOOTBALL PLAYERS
Many research projects that deal with the transformations of morphological characteristics have pointed out their extensive complexity, considering the fact that they are the result of genetic factors (endogenic influence) as well as factors pertaining to the environment (exogenic factors), where it is necessary to point out that the influence of genetic factors is not the same for all of the latent morphological dimensions. Òhe different positions of the biacromial and bicristal range in the latent and taxonomic structure of morphological characteristics that have contributed to the actualization of the problem of the relation between the first and second horizontal axis of the body, as well as their relations to the other components of morphological status. Taking that viewpoint, we defined the aim of this research to identify those morphological characteristics which are to the greatest extent related to the development of the horizontal axes. Using a sample of 130 athletes, handball players (N=70) and soccer players (N=60), aged 16 to 27, all of whom play in national leagues, and using a system of 21 anthropometric variables, we analyzed the relations between the first and second horizontal axis of the body, and their connection to the development of the remaining morphological characteristics. The first horizontal axis was defined as the biacromial range and the other as the bicristal range, while the remaining morphological characteristics were defined as the 19 standard measurements of longitudinal and transversal dimensionality, volume and body mass, and subcutaneous fatty tissue. When calculating the connection between the first and second horizontal axis and the remaining variables of the morphological system, we used the Pearson correlation coefficient. In addition, we calculated the dimorphism index for the biacromial and bicristal range as the point of the biserial correlation between the peripheral types of sport and every horizontal axis. It has been determined that in the case of handball players, it is possible to talk of biacromial and bicristal variants of an ectomesomorphic body type, while in the case of soccer players, of a biacromial variant of an ectomorphic type and a bicristal variant of an endomesomorphic body type. Both in the case of the biacromial and bicristal range, the dimorphism is pronounced among athletes who belong to different populations.

CLINICAL USE OF CLOPIDOGREL IN ACUTE CORONARY SYNDROME
Acute instable atherosclerotic plate in the basis of the pathophysiology of the acute coronary syndrome and it is divided on two big groups: a) acute coronary syndrome without ST elevation (NONSTEMI) and b) myocardial infarction with ST elevation (STEMI). Clopidogrel belongs to the group of antiaggregation drugs which inhibit ADP receptors and on that way prevent platelets aggregation. The clinical confirmation of the clopidogrel efficiency is confirmed trough 4 big clinical studies: CAPRIE, CURE, COMMIT/CCS 2 and CLARITY-TIMI 28 studies. In CAPRIE study, clopidogrel showed moderate but significant advantage comparing to aspirin in prevention of the secondary ischemic cerebrovascular stroke and myocardial infarction. The results of CURE study showed that doubled combined therapy with clopidogrel and aspirin brought the reduction of the relative risk of cardiovacular events with patients with acute coronary syndrome without ST elevation. The results of this study showed that the group of patients which received clopidogrel beside aspirin and thrombolytic therapy it came to the reduction of the occluded arteries. In COMMIT were also involved the patients with the acute myocardial infarction with ST elevation. Total number of lethal cases of the repeated myocardial infarctions or acute brain stroke was smaller in a group which was receiving clopidogrel beside thrombolytic therapy and aspirine in comparison with the placebo group. The results of CLARITY and COMMIT studies gave us recommendation that patients with acute myocardial infarction with ST elevation which have thrombolytic therapy or percutaneous coronary intervention should receive clopidogrel as well.

THE ALERGIC INFLAMMATION OF RESPIRATORY TRACT (INFLAMMATION IN CONTINUITY)
Allergic disease are actual pathologic condition in medicine. From this diseases can get ill people of any age, both sex, and the number of patients with allergic diseases rapidly increase in countries of progressive world. This disease are wide - spread, with tendency of increase, and they can have fatal result in extreme cases. Because of high prevalence of morbidity and complications they have, allergic diseases are health problem. According to World allergic organization, more than 40 % of population in world will be atopic. In our environment this diseases are increasing, because of bad ecological condition from one side, and from the other side of genetic influence, and on the top of ladder are allergic diseases of respiratory system. The mayor key process in atopia is continuous and plentiful production of IgE antibody.

GOITERS NODES THYROID GLAND AS A RESULT OF MODIFIED APOPTOSIS AND METHODS FOR DETERMINING
Hyperplasia in goiter may be associated with altered apoptosis thyrocytes. There are numerous techniques for the detection and quantification of apoptosis. Some of them were light microscopy, electron microscopy, flow cytometry, studying the activities of caspase, DNA fragmentation and so on. In patients with multinodular endemic goiter after six months of iodine load, number of apoptotic thyrocytes increased by ten times, Bcl-2 is missing and Bax appeared in thyrocytes. Excess iodine in molecular form causes apoptosis in thyrocytes creating free radicals, mitochondrial damage and release of cytochrome c. Research shows that the level of sFas in the serum of patients with multinodular goiter increased compared to normal controls, it can still point to the reduced expression of Fas protein on the surface of cells that then leads to increased thyroid cell proliferation. Further study of apoptosis in goiter combined morphological and biochemical methods are important for better diagnosis and treatment of diseases.
