RESUMEN
The methanol extract of Inula viscosa (IVM) was investigated for its antioxidant potential using the DPPH and ABTS radical scavenging as well as iron chelating assays (ICA). The total phenol (TPC) and flavonoid contents (TFC) of IVM were determined using the Folin-Ciocalteu and aluminum trichloride methods, respectively. Antimicrobial activity of different concentrations of I. viscosa methanol extract was investigated by disc diffusion and broth microdilution method. The IVM extract was found to be containing TPC (236.78 ± 7.63 mg GAE/g) and TFC (94.36 ± 1.86 mg QE/g). Antioxidant activity IC50 values for the DPPH, ABTS and ICA assays were found to be 277.7 ± 3.68, 2.44 ± 0.02, and 222.1 ± 0.71 µg/mL, respectively. The MIC values of the IVM on the tested microorganisms ranged from 0.48 to 7.81 mg/mL. Furthermore, IVM extract was demonstrated 18.32 ± 1.37%, 23.06 ± 1.05%, 4.72 ± 0.13%, 15.13 ± 0.37% and 37.64 ± 4.02% inhibition against tyrosinase, α-amylase, α-glucosidase, AChE and BChE, respectively. In the results of LC-MS/MS analysis, acacetin, quercetin, chlorogenic acid and protocatechuic acid were determined as most dominant compounds. These findings suggested that this plant may be a natural resource for creating novel medicinal compounds.
RESUMEN
Background/aim: Determining the epidemiological characteristics of M. bovis strains isolated from human and animal tuberculosis cases will assist in taking more appropriate and effective control measures in controlling tuberculosis originating from animal Materials and methods: In this study, 32 M. bovis isolates of animal origin and 10 of human origin were isolated and identified in the Çukurova region between March 2011 and June 2012. The 12-locus MIRU-VNTR and spoligotyping methods were used. Results: Six different patterns were determined by spoligotyping and 10 by MIRU-VNTR. When both methods were used together, the number of patterns was found to be 28; MIRU4, MIRU26, MIRU31, and MIRU40 had the highest locus discrimination powers by MIRU-VNTR. The isolates concentrated in the SB0120 pattern at the rate of 42.85% in spoligotyping. By the same method, it was seen that 7 isolates were M bovis ssp. caprae pattern and 2 human isolates were M. bovis BCG pattern. Nevertheless, spoligotyping and MIRU-VNTR patterns showed that 5 M. bovis isolates of human origin were 100% compatible with isolates originating from cattle. Conclusion: In this study, we determined that the use of spoligotyping and MIRU-VNTR methods together was found to be more sensitive in the epidemiological analysis of M. bovis isolates.

In this study, female rats induced with chemical cystitis were administered the hormone human choriogonadotropin (HCG), and it was aimed to reveal the usefulness of HCG in the treatment of interstitial cystitis/bladder pain syndrome. The materials for this study were 32 Wistar albino female rats. The study groups were formed as follows: the cystitis group (Group 1), the cystitis + HCG protection group (Group 2), the cystitis + HCG treatment group (Group 3), and the control group (Group 4), with eight rats in each group. In this study, blood and urine samples were taken from the rats, they were euthanized, and their bladders were removed for glutathione, malondialdehyde, tumor necrosis factor alpha, and interferon gamma measurements. It was observed that tissue damage in Group 2 was lower than that in the other two groups. Glutathione levels in Groups 2 and 4 were significantly higher than in Groups 1 and 3 (p = 0.01). Malondialdehyde levels of Groups 2 and 4 were significantly lower than the values in Groups 1 and 3 (p < 0.001). When the cystitis groups were compared in terms of their interferon gamma and tumor necrosis factor alpha levels, the lowest interferon gamma and tumor necrosis factor alpha levels were detected in Group 3. It was found that HCG has positive effects on experimental cystitis in rats. This study revealed that HCG should be researched as a therapeutic agent and formed a step for studies to be carried out on this subject.

The objective of our study was to compare the serum concentrations of procalcitonin (PCT), neopterin, tumor necrosis factor alpha (TNF-α), prostaglandin E2, malondialdehyde, interleukin 8, and gamma interferon (IFN-γ) in neonatal calves with septicemic colibacillosis (n = 15) with healthy controls (n = 15). Septicemic colibacillosis was diagnosed based on clinical signs and the isolation of Escherichia coli from heparinized blood in clinically suspected cases. PCT, neopterin, TNF-α (p < 0.05), and IFN-γ concentrations in calves with septicemic colibacillosis were significantly higher than in the healthy controls (p < 0.01). Serum PCT concentrations were ~4 times higher in the calves with septicemic colibacillosis than in the healthy calves, suggesting that PCT could be a useful marker of septicemic colibacillosis in neonatal calves.

BACKGROUND: Crimean-Congo hemorrhagic fever (CCHF) is known to be associated with cardiac damage. Brain type natriuretic peptide (BNP) is secreted from stressed myocardium. OBJECTIVES: This study investigated that BNP levels in CCHF and its association with clinical course of disease. METHODS: Consecutive CCHF diagnosis confirmed patients were enrolled to the study. Results of patients were compared with age-sex-matched healthy volunteers. Blood samples for BNP levels were collected from the patients during emergency room applications. Mortality, hospitalization duration and other disease severity predictors (thrombocyte count, hemoglobin, white blood cell count, alanine aminotransferase, aspartate aminotransferase, prothrombin time, lactate dehydrogenase, international normalized ratio, activated partial thromboplastin time) were recorded. These parameters' correlations with BNP levels were analyzed. RESULT: Forty-three CCHF patients and 28 control subjects recruited to the study. Groups were similar for age and gender. There was no mortality. Levels of BNP were found to be significantly higher in patients than control subjects (100.4±45.4 vs. 78.0±40.4, P=0.033). But BNP levels were not correlated with duration of hospitalization and disease severity predictors (P > 0.05). CONCLUSIONS: This study showed that BNP levels are modestly increased in CCHF but this increase does not correlated with disease severity predictors.
RESUMEN
BACKGROUND: Apoptosis is a main regulator in responses of cellular immunity throughout systemic viral infections. Perforin, soluble Fas ligand, caspase-3 and caspase-cleaved cytokeratin-18 (M-30) are mediators of apoptosis. The aim of this study is the evaluation of Crimean-Congo hemorrhagic fever (CCHF) disease changes in the levels of these apoptotic markers and the relation of these changes with disease severity. METHODS: Forty-nine hospitalized children with CCHF and 36 healthy controls were enrolled in this prospective study. The CCHF patients were classified into 2 groups based on disease severity (severe group and nonsevere group). Demographic characteristics and clinical and laboratory findings of all patients were recorded on admission. RESULTS: Serum perforin, caspase-3 and soluble Fas ligand levels were found to be significantly higher both in the severe and nonsevere CCHF groups than the healthy control group (P < 0.05), but there was no significant difference in these apoptotic markers between severe and nonsevere CCHF groups (P > 0.05). In addition, serum M-30 levels did not differ significantly among all groups (P > 0.05). There was a positive correlation between serum values for perforin, caspase-3 and M-30 and the disease's severity criteria such as aspartate aminotransferase and/or alanine aminotransferase. The serum levels of all these markers were negatively correlated with disease severity criteria such as the platelet count. CONCLUSIONS: In this study, we concluded that the interactions of cytolytic granules containing perforin and caspase cascade and Fas-FasL may play an important role in the pathogenesis of CCHF in children.

BACKGROUND/AIMS: Patients with ulcerative colitis still need effective therapy without major side effects. It has been found that strontium can suppress NFκB activation induced by TNF-α. This opens a gate to a new anti-TNF agent which is cheap and can be given orally. We for the first time aimed to investigate the effect of strontium chloride (SrCl2) on inflammation in experimental colitis. METHODS: Thirty female Wistar albino rats were divided into 5 groups each containing 6 rats. The rats in groups 1 and 2 served as the healthy control and colitis group, respectively. The rats in groups 3, 4, and 5 had colitis and received 40 mg/kg SrCl2, 160 mg/kg SrCl2, and 1 mg/kg prednisolone by oral gavage, respectively. The rats were sacrificed for histological evaluation and determination of serum neopterin, TNF-α, and IFN-γ levels. RESULTS: The neopterin, TNF-α and IFNγ levels of group 2 was significantly higher than the other groups. The neopterin, TNF-α, and IFN-γ levels of controls and other treatment groups were comparable. There were a significant difference in macroscopic and microscopic healing between group 2 and other groups histologically. But there was not a significant difference within treatment receiving groups. CONCLUSION: SrCl2 had comparable therapeutic efficiency with prednisolone.
