Background: In this study, we aimed to determine platelet indices such as platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), Plateletcrit (PCT) platelet count (PLT) in lung cancer cases, and evaluate any relationships between these parameters and stage or histologic types. Materials and Methods: This retrospective study covered 44 lung cancer patients and 47 healthy subjects. Platelet indices including PLT, PCT, MPV, PDW were estimated and compared with normal subjects. The results were evaluated statistically. Results: The PDW value was significantly higher in the cancer group compared to the control group; however, the values for PCT and MPV were lower. Conclusions: We suggest potential use of platelet indices in diagnosis of lung cancer.

Primer $Sj{\ddot{o}}gren's$ Syndrome (pSS) is an autoimmune/inflammatory illness. The platelet indices (PIs) indicate the inflammatory response and activity/severity of many diseases. A vitamin D deficiency is accompanied by the increased tendency of autoimmune diseases. This study investigated whether the vitamin D levels are related to the altered platelet indices in pSS. A total of 261 individuals were included in this analytical cross-sectional study. The laboratory data of pSS patients were evaluated and the relationship between the PIs and vitamin D status was examined. According to these findings, in patients with pSS, the vitamin D levels were lower than the healthy control group (P<0.05). The vitamin D levels were negatively associated with PDW (P=0.012), but positively correlated with PCT (P<0.001). The cut-off point was obtained with receiver operating characteristics (ROC) curves for PDW: 12.53 (AUC 0.921, sensitivity 90%, specificity 85%), for PCT; 0.29 (AUC 0.660, sensitivity 68%, specificity 55%). In multivariate linear regression analysis, the most significant parameters for the effects of PDW are the following: vitamin D (${\beta}=-0.373$; t=-2.626; sig.=0.013) and plateletcrit (${\beta}=-0.308$; t=-2.13; sig.=0.040). A vitamin D deficiency may be accompanied by changes in PIs in pSS. A higher PDW and lower PCT supports the underlying inflammation, which may be vitamin D related useful parameters to consider in approaching to pSS.

Background: Platelets are blood elements thought to play a role in the immune system and therefore tumor development and metastasis. Platelet activation parameters such as mean platelet volume (MPV), platelet distribution width (PDW), and plateletcrit (PCT) can be easily evaluated with the whole blood count and have been studied as markers of systemic inflammatory responses in various cancer types. Our aim in this study was to evaluate the correlation between endometrial pathologies and MPV, PDW and PCT. Materials and Methods: A total of 194 patients who presented to our clinic with abnormal vaginal bleeding were included in our study. The patients were divided into 3 groups (endometrial hyperplasia, endometrial cancer, control) according to their pathology results. The groups were compared for MPV, PDW, and PCT values obtained from the blood samples taken on endometrial biopsy day. Results: The endometrial cancer patients were the oldest group (p=0.04). There was no significant difference between the three groups in terms of white blood cell count (WBC), platelet count (PC), and hemoglobin (Hb) level. The highest MPV (p<0.001), PDW (p=0.002), and PCT (p<0.001) levels were in the endometrial cancer group, and the lowest levels were in the control group. Conclusions: The easy evaluation of platelet parameters in patients who are suspected of having endometrial pathology is a significant advantage. We found MPV, PDW, and PCT to be correlated with the severity of endometrial pathology with the highest values in endometrial cancer. Studies to be conducted together with different laboratory parameters will further help evaluate the diagnosis and severity of endometrial cancer and precursor lesions.

This study was designed to know the effect of kimchi on the hematological and immunological parameters in vivo and in vitro, respectively. To study the effects of kimchi on the hematological parameters, rats(S.D., male) were divided into 4 groups and fed diets containing of 3%, 5% and 10% kimchi or kimchi free diet(control) for 6 weeks. The results of CBC(complete blood cell) tests obtained from the bloods of rates were as follows ; In 10% kimchi group, the level of WBC(white blood cells), RBC(red blood cells), Hgb(hemoglobin), Hct(hematocrit) were increased significantly than those of control group(p<0.05). MCV(mean corpuscular volume), one of the red cell indices, was also increased significantly in the animals fed 10% kimchi(p<0.05). RDW(Red cell distritution width) and PCT(plateletcrit) was lowest in 10% kimchi group(p<0.05). To examine the effects of kimchi on immune cell growth in vitro, three types of mouse immune cells-spleen cells, bone marrow cells, thymus cells-were cultured with extracts of salted Chinese cabbage, fresh kimchi and fermented kimchi(for 1 week) for 12 or 20 days. Control was supplemented with PBS(phosphate buffer saline) excluding kimchi extract. The results of spleen cell, bone marrow cell, and thymus cell cultures showed similar tendency: control medium accelerated death of cells, extracts of salted Chinese cabbage reduced the rate of cell death, and extracts of fresh kimchi and fermented kimchi promoted cell growth. From these results, it could be suggested that kimchi possibly has an effect on the hematopoietic ability and increases immune cell development and growth in vivo.

Background: Mycobacterium avium subspecies paratuberculosis (MAP) causes a chronic and progressive granulomatous enteritis and economic losses in dairy cattle in subclinical stages. Subclinical infection in cattle can be detected using serum MAP antibody enzyme-linked immunosorbent assay (ELISA) and fecal polymerase chain reaction (PCR) tests. Objectives: To investigate the differences in blood parameters, according to the detection of MAP using serum antibody ELISA and fecal PCR tests. Methods: We divided 33 subclinically infected adult cattle into three groups: seronegative and fecal-positive (SNFP, n = 5), seropositive and fecal-negative (SPFN, n = 10), and seropositive and fecal-positive (SPFP, n = 18). Hematological and serum biochemical analyses were performed. Results: Although the cows were clinically healthy without any manifestations, the SNFP and SPFP groups had higher platelet counts, mean platelet volumes, plateletcrit, lactate dehydrogenase levels, lactate levels, and calcium levels but lower mean corpuscular volume concentration than the SPFN group (p < 0.017). The red blood cell count, hematocrit, monocyte count, glucose level, and calprotectin level were different according to the detection method (p < 0.05). The SNFP and SPFP groups had higher red blood cell counts, hematocrit and calprotectin levels, but lower monocyte counts and glucose levels than the SPFN group, although there were no significant differences (p > 0.017). Conclusions: The cows with fecal-positive MAP status had different blood parameters from those with fecal-negative MAP status, although they were subclinically infected. These findings provide new insights into understanding the mechanism of MAP infection in subclinically infected cattle.
