Introduction: In over of 99% cases of cervical cancer its appearing is preceded by persistent cervical epithelium infection caused by high-risk oncogenic types of human papillomavirus (HPV). The aim of the study was to examine the distribution of high-risk oncogenic HPV types compared to patohistological diagnoses of cervical diseases in women. Materials and methods: The study included 56 women with suspected premalignant and malignant cervical lesions, due to suspected colposcopic and cytological findings (Papanicolaou test). The HPV typing by "in situ" hybridization method on high-risk HPV types 16, 18, 31 and 33 was performed in all patients from cervical smear as well as cervical biopsy. Histological findings of cervical biopsy was a "gold standard" in the analysis of materials. Results: Histologically detected premalignant or malignant changes of the cervix were found at 34 (60.7%) of all 56 examined women: 17 of them had LSIL, 13 of them had HSIL, while 4 had squamous cell carcinoma. A positive HPV test had a 47 (84%) of them with a prove of the presence of one or more types of HPV. The most common type of virus was HPV 16 and it was detected in 27 (48.2%) women, followed by HPV 31 that was detected in 26 (46.4%) women, HPV 18 in 18 (32.1%) of women and HPV 33 in 4 (7.1%) women. The infection caused by oncogenic type HPV16 was significantly more frequent in patients with HSIL and cervical cancer (p<0,001), while the infection caused by oncogenic type HPV 31 was significantly more frequent in patients with LSIL and cervicitis (p=0,003). The distribution of HPV 18 and HPV 33 types was not statistically significantly different in patients with different histological findings (HPV 18, p = 0.41; HPV 33, p = 1.0). Conclusion: Based on our results we can conclude that there is a good correlation of HPV infection with pre-malignant cervical lesions and cervical cancer. The incidence of HPV type 16 infection increased with severity of cervical lesions and it is usually detected high-risk oncogenic type virus in women with severe cervical lesions type like HSIL and cancer are. HPV 31 is the most common high-risk type of HPV of mild type lesions, like LSIL and cervicitis are. We believe that women infected by high-risk oncogenic HPV types, although without histologically diagnose of cervical lesion, should be more frequent controle by colposcopy and cytology (Papanicolaou) test, because of possible disease progression to a more advanced level.

Najčešći maligni tumori kože epidermoidnog porekla su bazocelularni (BCK) i skvamocelularni (SCK) karcinom. U 90 % slučajeva nastaju na fotoeksponiranim delovima tela i direktno su povezani sa oštećenjima kože nastalim dugotrajnim izlaganjem UV zracima, obično kod osoba starijeg životnog doba i svetle puti. Od njihovih posledica godišnje u svetu umre 65000 ljudi. Najvažnija karika u sprečavanju nastanka ovih tumora jeste prevencija, dok njihovo rano prepoznavanje omogućava adekvatniji hirurški tretman sa poštedom okolnog tkiva. Osnovni cilj ovog rada je ispitivanje histopatoloških i kliničko-morfoloških karakteristika BCK i SCK kože glave. Analizom je obuhvaćeno 439 karcinoma (297 (67,7%) BCK, 126 (28,7 %) SCK i 16 (3,6%) BCK+SCK), među kojima je preko 60% dijagnostikovano kod muškaraca, najčešće u sedmoj i osmoj deceniji života, sa najvećom učestalošću BCK na nosu, odnosno na koži gornje polovine kože lica i SCK na usnama, odnosno na koži donje polovine kože lica. Svi karcinomi kože glave bili su češći na desnoj strani. Klinički i morfološki, najveći broj BCK manifestovao se ulceroznim oblikom prosečne veličine 1,2cm i mešanim histološkim tipom, a SCK vegetantnim oblikom prosečne veličine 1,55cm i histološki gradusom I. Najveći broj BCK i SCK bio je odstranjen u celini, za razliku od kombinacije ova dva tumora u kojima je u većini slučajeva bila neophodna i naknadna hirurška intervencija.

Starenje kože je spor, ali progresivan degenerativni proces. U literaturi se definišu dve varijante bioloških okolnosti starenja kože: jedna objašnjava prirodno, fiziološko starenje, u funkciji vremena, na genetskoj osnovi - hronološko ili intrinzičko starenje (engl.chronological/intrinsic skin aging ) koje se klinički zapaža kao glatka, tanka, fino naborana koža, a druga povezuje i analizira promene na koži nastale pod uticajem spoljnih činilaca, uglavnom UV zračenja, - tzv. solarno ili ekstrinzičko starenje (engl. photoaging / extrinsic skin aging). Normalno ili intrinzičko starenje je praćeno atrofijom epiderma i derma, destrukcijom kolagenih i elastičnih vlakana, uz poremećaj proliferacijske homeostaze brojnih ćelija i posledične pojave benignih i malignih lezija kože.

The process of multipotential lymphatic stem cell maturation and differentiation into immunocompetent T cells is accomplished by the expression and deletion of specific surface CD antigens. The CFU-Lstem cells enter the medulla of the thymus via a post capillary venule and then migrate to the periphery of the thymic lobule. The presence of CD2 and CD7 molecules on the cell surface indicates an early stage of differentiation. This is followed by expression of the CD1 molecule, indicating the midstage of Tcell differentiation. As maturation progresses, the cells express TCRs, CD3, CD4, and CD8 molecules. It seems that intensity of interreacion between TCR/co receptor molecule complex and self peptide/MHC complex determine the outcome of the thymocite selection process. If the lymphocyte recognizes self MHC and self or foreign antigen, it will survive the selection (positive selection); if not, death of the cell will occur. Cells that pass the positive selection test leave the cortex and enter the medulla. Here they undergo another selection process in which cells directed to selfantigen displayed by self MHC are eliminated (negative selection). Cells that survive that selection then become either cytotoxic CD8+ Tlymphocytes or helper CD4+ Tlymphocytes.

Dendritic cells (DCs) are antigen presenting cells which trace origin from bone marrow cells. These cells are discovered and described by Steinman i Cohn (1973) in peripheral lymphoid organs of mice. The cellular membrane of DCs are place of expression of plenty immunoregulatory molecules such as MHC class I and II, co stimulatory, and adhesion molecules, as well as many receptors for different cytokines. Armed on this way, DCs are one of the most effective antigen presenting and immunoregulatory cells. Moreover, role of DCs in development of immune reaction can be crucial due to they are one of the most important cellular “link” between native and adaptive immunity. DCs are engaged in mechanisms of antigen processing and presentation, induction of immune reaction, establishing immune tolerance and immune reaction regulation, balancing the immune reaction between autodestruction and protection of “self” cells. These functions makes that DCs play very important role in development of some pathological conditions and diseases such as autoimmunity, allergies and quality of anti-tumor and anti-microbe defense. Unbalanced immune reaction is hallmark of all cited diseases and immunopatological conditions, so that the function of DCs should be explored on the better way.

Adipose tissue secretes bioactive peptides, termed 'adipokines', which act locally and distally through autocrine, paracrine and endocrine signals. Those signals influences the answers of other tissues and organs including hypothalamus, pancreas, liver, sceletal muscles, endotel an immune system. Increased production of most adipokines impacts on multiple functions such as appetite and energy balance, immunity, insulin sensitivity, angiogenesis, blood pressure, lipid metabolism and haemostasis, all of which are linked with cardiovascular disease. Leptin is a critical mediatorof energy balance that relays information regarding the depletion or accumulation of fat stores to the brain. Althoughmany of leptin's effects result rb from a direct action ofleptin on hypothalamic neurons, the functional leptin receptor(long-form or lep ) is also found on many tissues outside the central nervous system (CNS), including immune cells. Obese individuals seem to be resistantto the hypothalamic effects of leptin (maybe because of defective blood-brain barrier transport), the catabolic pathways designed to reduce appetite and increase energy expenditure are not activated and excess body weight is maintained). Adipokines like adiponectin and leptin, at least in physiological concentrations, are insulin sparing as they stimulate beta oxidation of fatty acids in skeletal muscle. The role of resistin is less understood. It is implicated in insulin resistance in rats, but probably not in humans. Adiponectin and resistin are adipocyte-derived polypeptide hormones playing a role in metabolic homeostasis. Their plasma levels are inversely (adiponectin) or directly (resistin) correlated to obesity (and in a patients with type 2 diabetes mellitus) and they have opposite effects on insulin sensitivity. Adipocytes secretes also adipsin, factor B and factor C. In-depth understanding of the pathophysiology and molecular actions of adipokines may, in the coming years, lead to effective therapeutic strategies
