Dipeptidyl peptidase IV is ecto-enzyme which is present on the cell surface of large number of cells and particularly of T-lymphocytes. It takes part in immune reactions and regulation of immune response, while antigen stimulation of cells increases percentage of expression of DPPIV on their cell surfaces. Since the immune response is different for chronic tonsillar disease of tonsilla palatine, idiopathic tonsillar hyperplasia ITH and recurrent tonsillitis RT, and considering the fact that DPPIV takes part in activation of T and B-lymphocytes stimulated by antigen, we presume that different activities of DPPIVexist in tonsillis and blood of persons diseased of different types of chronic tonsillitis, ITH and RT. The main goals of research are determination of activities of DPPIV on lymphocytes of tonsillas and serum of persons diseased of ITH and RT as well as histochemical and immunohistochemical determination of DPP IV localisation on lymphocytes of examed tonsillas. Two groups of patients are included: nineteen persons with ITH and thirteen persons with RT, while the control group was contained of thirty nine persons with diagnosis systematic lupus erythematosus (SLE) and fiftteen health persons. The research was done on 32 tonsillas created by tonsillectomia of persons with ITH and RT and 86 blood samples of all 86 persons. The results of research show histochemical localisation of enzyme activity of DPPIVin T-dependent zones of tonsilla and it is originating from activated T-lymphocytes. The enzyme activity of DPP IV on tonsillar lymphocytesis is higher in case of IHT compared with RT. By this research we conclude that deifferent activity of DPPIV on tonsillar lymphocytes for ITH and RTpresumes the difference of immuno response of tonsillas during these tonsillar diseases.

Anorectal abscesses and fistulas are problems that are commonly encountered together. Occasionally, their management can prove to be formidable, constantly challenging the clinical and surgical skills of the practicing surgeon. This article reviews the etiology, presentation, and treatment of anorectal abscesses and fistulas.

Parameters of anaerobic capacity were investigated in the group of 90 young subjects classed into diferent groups depent on their physical fitness. The group consisted of 30 wrestlers, 30 rowers and 30 students. Basic antropometric parameters were taken for each person and than Wingate anaerobic test was administrated. The aim of this investigation was to measure anaerobic parameters and determine weather there was a difference among sportsman and non sportsman. All parameters of Wingate test (anaerobic power, explosive power, anaerobic capacity) were significantly higher in the group of sportsman. (p0.05) Also, the highes values od anaerobic parameters were detected in the group of wrestlers, since this is typicaly anaerobic sport. The lower values were measured in the group of non sportsman, as expected.

There are different reports regarding the characteristics of examined quality of life (QOL) in patients with combined coronary and valvular surgery. Objective was to compare the quality of life changes after isolated coronary and associated coronary and valvular surgery. From February to May 2002, we prospectively studied 243 consecutive patients, who underwent elective CABG. The Nottingham Health Profile Questionnaire part I (NHPpart I) was used as a model for QOL determination. NHPpart I contains 38 subjective statements divided into six sections: physical mobility (PM), social isolation (SI), emotional reaction (ER), energy (En), pain and sleep. The scores ranged from zero to 100, by adding the item weight, determined by Thurstone method of paired compares, to every positive answer. We distributed the questionnaire to all patients before and six months after CABG. Two hundred twenty six patients filled in the postoperative questionnaire. An isolated coronary heart disease was present in 218 patients (89.71%), and associated coronary and valvular disease in 25 patients (10.29%). Preoperatively, there is no difference in QOLamong the examined groups. After operation, quality of life was improved in 84.65% (171/202) of patients using coronary surgery and in 79.17% (19/24) of patients using combined (coronary and valvular) surgery. Quality of life was statistically improved in the first group of patients in all sections, and in the second group of patients in 4 sections (PM, En, pain and sleep) (p<0.05). There is no significant correlation between the quality of life changes after operation and the type of surgical procedure. By univariate and multivariate logistic regression, combined procedure distinguished as the independent predictor of QOL worsening in the ER section (p=0.012, OR=3.62, 95% CI 1.32-9.92). Six months after CABG quality of life was significant better in most of patients in both studied groups. Associated coronary and valvular surgical intervention distinguished as the independent predictor of quality of life worsening in the ER section.

In essential hypertension, hemodynamic changes in systolic and diastolic function acompany left ventricul hypertrophy ussualy. Both of these cardiac function can be detected with echocardiography and were measured during this study. 23 patients with moderate essential hypertension were treated with cilazapril plus small doze of diuretic (hydrochlorothiazide) once daily for 120 days. On the begining we found diastolic disfunction, but after the treatment there was a significant improvement in isovolumic relaxation time, early diastolic filling pattern and normalized left ventricular early/ atrial filling ratio. Cilazapril + diuretic combination in a dose once daily controlled blood pressure satisfactory, too. Parameters of systolic function were in the normal levels and there were no significant changes between the two determinations. Thickness of the interventricular septum and posteroinferior wall did not change significantly after 16 weeks of therapy, probably because of too short time of investigation.

The injuries of genital organs are commonest today regarding to the fact that there are different kinds of firearms and contact mines, although testicles are well protected in thigh area. In cases where we have maximum testicles injuries the conservative surgical treatment should be applied, considering the fact that testicles have great power of "restitucio ad integrum".

In well organized societies, accept of material and technical progress, planning of the family and existing of human resources is of great importance. Every civilized society is tancing care of human potential, planning and progress, eather to stimulate or control of natural increase are bringing the suitable demographics of standards. With better family planning asspecially motivatiy the couples to decide for reproduction and delivering of optimal namber of children in optimal period between deliveries and in optimal ages, brings to decreased mortality among new-borns, and also their mathers. 

It is known that the intoxication with heavy metals and pesticides is most often unmedical poisoning. In contrast to other heavy metals, for example: mercury, lead, cadmium and zinc, toxic copper activity and the mechanism of its effect are not known enough and they are not yet explained. Because of that, the aim of this work was ( with acute dog intoxication with copper sulfate ) to contribute to better clearing of biochemical mechanism as a result of copper toxical effect and to make analysis of its tissue distribution. Researching was done on adult dogs, both sexes, different races and body mass of 14- 20 kg, who were given a 10% water solution of copper sulfate in the dosage of 33mg/b.m. divided into 5 equal doses. The analysis of biochemical blood structure took the following things: total proteins, albumins, globulins, total lipids, chole2+ sterol, glucoze, transaminase (AST,ALT), catalase, peroxidase, vitamin C, proteine SH, the contretation of Cu in the serum 2+ and the content of Cu in the tissues. The results are presented in the charts and graphic presentation. All these changes can be the important directions in an biological monitoring as a biochemical indication of copper pollution in the surroundings.

Perinatal infection occurs as a consequence of the intrauterine (congenital) infection, intrapartal infection, or the
newborn infection in the course of its nursing. Congenital cytomegalovirus infection is a most frequent intrauterine infection. The prevalence of congenital CMV infection given by different authors varies significantly, but the majority of them
mention that it is in the range from 0.5 to 2.5 % of the number of the live-born. Significance of this disorder is underlined by
the fact that about 20% of intrauterine infected newborns have later serious problems in their development. The signs of fetal
impairments with congenital CMV infection can be noticed with about 10 % of the infected newborns at the very birth. The
mortality rate among these newborns is high even about 30 % of them exhibit heavy signs of the disease and die very soon
after the birth. Even with 70 % of the newborns with the symptoms of congenital CMV infection it is possible to notice at the
birth the presence of the symptomatology related to CNS, and this is of predicative significance for the later unfavorable
development of the infant. It should be pointed out that, in contrast to intrauterine infection, which provenly yields to fetal
impairments, there are no reliable data that would point to undesired outcomes of intra- or postpartal infections. The work
gives a survey of contemporary knowledge about cytomegalovirus infection in perinatology, as well as about the possibilities of its diagnosis and treatment.

Nuclear magnetic resonance (NMR) or magnetic resonance imaging (MRI) today is the most powerful review method of a human body. Method is based on effect strong magnetic field and on demonstration of natural physical characteristics of nucleus. Hydrogen atom is a part of almost every compound in our body (water, lipids, proteins and nucleid acids).
When we exposed body to strong magnetic field hydrogen nucleus orients in direction of field, which cause resonance and
6 8 emission of radio signals. Resonance frequency for MRI is in range from 10 Hz to 5x10 Hz, which is equal to energies from -28 -25 6x10 J to 3x10 J.
