Abstract
Surgically perforated stomach (since direct injury in rats until persisting defect and huge adhesions (day 1, day 7)) fairly represent an unresolved cytoprotection issue, and thereby, we focused resolving of the immediate triad, particular vascular failure (vessels 'disappear'/empty), prolonged bleeding, debilitated defect large widening. Agents (mg/kg) or saline (controls) were given at 1 min post-injury as an abdominal bath (10 ml/rat throughout 2 min). Within 1 - 15 min post-injury period, with cytoprotective BPC 157 (0.01 μg), the rapidly restored vessels 'run' (vessels filled/reappeared) toward the perforated defect, and there is less bleeding, and defect contraction; advanced perforated lesion healing (day 1) to complete healing (day 7), and less adhesions. With pantoprazole (10 mg), early (vessels (worsening), bleeding (prolongation), defect (attenuated widening)) effect means eventual lesions and adhesions severity as in controls. Ranitidine (10 mg) early effect (vessels (improvement), bleeding (less bleeding), defect (eliminated widening, defect not changed)) means final lesions attenuation, but not complete healing, less adhesions. L-NAME (5 mg) early (vessels worsening, less bleeding, attenuated defect widening) and final (lesions aggravation, more adhesions) effect, versus L-arginine (100 mg) early (vessels improvement, more bleeding, attenuated defect widening) and final (lesions attenuation, less adhesions) effect, combined few simultaneously occurring nitric oxide (NO)-system distinct processes. Finally, in the stomach tissue surrounding defect, increased malondialdehyde (MDA)- and decreased NO-values, BPC 157 reversed to the normal healthy values, and mRNA expression studies (Cox2, VEGFa, Nos1, Nos 2, Nos3, Nkap (NF-kappa-B-activating protein gene)), done at that very early post-perforation-time, indicate a way how BPC 157 may act beneficially in the perforated stomach lesion throughout NO- and prostaglandinds-system.

Abstract
Varicocele is frequent but correctable cause of male infertility. Varicocelectomy is the most commonly performed operative procedure for varicocele. Majority of varicocele patients do not have fertility problem, therefore surgical correction is not recommended in all prevalent cases. On the other hand, varicocele is a progressive condition in some cases and individual with varicocele is at risk for developing impairment which can ultimately lead to semen deterioration and consequent infertility. Selection of patients with varicocele that will progress and cause infertility is beyond our current diagnostic capabilities. Diagnostic assessment of varicocele depends on physical examination and scrotal ultrasound/doppler. Infrared digital thermography of scrotum is a non-invasive and objective diagnostic method for early varicocele detection by means of temperature measurement on the scrotal skin surface. The criteria for diagnostic use of scrotal thermography were recently presented. We hypothesize that the infrared digital thermography of scrotum could be the cornerstone in detection of varicoceles that tend to progress with impairment of semen quality and will require surgical correction, among all prevalent varicocele cases.

Abstract
The aim of this study was to assess scrotal thermography in diagnostics of varicocele and suggest potential diagnostic criteria. Twelve patients with clinically diagnosed varicocele were examined with scrotal infrared digital thermography, physical examination and ultrasound/doppler. The main outcome measure was evaluation of thermography diagnostic criteria for varicocele. Mean temperature at left pampiniform plexus was ≥ 34 °C in 83%, and at right pampiniform plexus in all cases was ≤ 34 °C. In 92% of patients, temperature at the left testicle was ≥ 32 °C, whereas at the right testicle it was >32 °C in 50% patients. Temperatures between left and right pampiniform plexus and between left and right testicle were significantly different with P < 0.0001 and P < 0.006 respectively. In all patients, temperature difference between pampiniform plexuses was ≥ 0.6 °C. In 92% of patients, temperature at left pampiniform plexus was equal or higher to thigh temperature with the mean temperature difference of 1.1 ± 1.1 °C. Temperature at right pampiniform plexus was colder than the thigh in 92% of patients. This study suggests diagnostic criteria of five thermographic signs to easily diagnose varicocele. Scrotal thermography presents feasible, short and low cost diagnostic method for varicocele. Further study on a larger number of patients and healthy participants is needed to evaluate sensitivity and specificity of this method.

Abstract
The promotion of tumor growth is due to a combination of several mechanisms, including angiogenesis and the abundance of cell-derived inflammatory cytokines. The aim of this study was to investigate the serum levels of interleukin 17 (IL-17) and the expression of p53 and Vascular Endothelial Growth Factor (VEGF), in order to determine the relationship between these markers and serum IL-17 levels in patients with colorectal carcinoma. Serum levels of the proinflammatory cytokine IL-17 in patients with colorectal carcinoma (CRC) (n=40) and in a healthy group (n=37) were analysed by ELISA. Surgically resected specimens of 59 colorectal carcinomas were studied by immunohistochemical staining for VEGF and p53. Analyses by ELISA showed significantly higher IL-17 serum levels in patients with colorectal carcinoma than in control subjects (IL-17; mean 128.52+/-47.62 pg/ml vs. mean 101.91+/-22.46 pg/ml; p=0.022). We also found an inverse correlation between p53 expression and the level of IL-17 in the serum of patients with CRC. In fact, the serum concentration of IL-17 was significantly higher in patients who did not express p53 (p=0.023). There was no significant correlation between the expression of p53 and VEGF. However, concomitant expression of VEGF and p53 showed a significant correlation with the histological and nuclear grade of the carcinoma. The data presented in our study indicate that IL-17 might act as a valuable tumor marker in patients with CRC and that combined analysis of p53 and VEGF expression might provide additional information about tumor features.

Abstract
Chondrocytes present in articular cartilage survive as a resident cell population throughout the lifespan of the individual organism. However, articular chondrocytes as other cells also undergo apoptosis and there is an ever increasing list of diverse stimuli that can induce this phenomenon in vitro. Our main interest was to investigate potential cytotoxic effects of vitamin C (L-ascorbic acid) on human articular chondrocytes. The present study suggests that vitamin C can induce apoptosis in a cell culture of chondrocytes after 18 h of cultivation. Apoptosis-inducing activity of L-ascorbic acid is dose dependent and significantly affected by the presence of serum. The increased number of vitamin C induced apoptotic cells was associated with DNA fragmentation and morphological changes of the cells.

Abstract
To study the effect of age and antigenic priming on the development of gingivitis, 33 healthy rats were placed in contact with Streptococcus mutans, Actinomyces viscosus, Fusobacterium nucleatum, and Bacteroides gingivalis. On days 0, 3, 7, and 14 after inoculation, the gingival condition was judged clinically and histologically, and serum antibody titers against the bacteria were measured. The rats were divided into three groups: 1 month old, 3 months old, and 3 months old immunized. None of the young rats developed gingivitis during the experiment, whereas half of the adult and all of the adult immunized rats bled on probing on days 7 and 14. In general, antibody titers against the bacteria were low in young rats, moderate in adult rats, and high in adult immunized rats. These results indicate that adult rats react stronger to plaque antigens than young rats and that previous contact with the antigens increases the reaction.
