May mean platelet volume levels be a predictor in the diagnosis of pelvic inflammatory disease

SummaryBackgroundOur aim in this study was to investigate whether mean platelet volume (MPV) value could be used as an early marker to predict pelvic inflammatory disease (PID).MethodsOverall, 44 patients with PID and 44 healthy women were included in the study. The control group consisted of 44 women who applied to the clinic for a routine gynaecological check-up, without chronic disease or a history of medication use. Owing to the fact that it would affect thrombocyte function, women who have the following conditions were excluded from the study: women who were taking anticoagulant therapy, oral contraceptives, nonsteroid anti-inflammatory medications and who had chronic diseases. The leukocyte count, platelet count, neutrophil ratio and MPV values were collected from PID and the control group. C reactive protein values of patients with PID were also noted.ResultsMPV values in patients with PID were lower than those in the control group. This reduction in MPV is statistically significant when the PID patient group is compared with the control group (p < 0.001). A negative correlation was discovered between platelet count and MPV values (p = 0.019, r = − 0.425). Receiver-operating curve analysis pointed out that MPV has greater area under curve value than neutrophil rate, leukocyte and platelet count (0.73, 0.64, 0.72 and 0.49 respectively).ConclusionSince the MPV value was significantly decreased in patients with PID, it may serve as an additional and even more valuable marker than leukocyte count in the diagnosis of PID.ZusammenfassungGrundlagenZiel dieser Studie war es zu untersuchen, ob das mittlere Thrombozytenvolumen (MPV) als früher Marker einer Erkennung von Entzündungen im Beckenbereich verwendet werden kann.Methodik44 Patienten mit Entzündungen im Becken und 44 gesunde Frauen wurden in die Studie aufgenommen. Die Kontrollgruppe waren Frauen, die die Ambulanz der Klinik zur gynäkologischen Routineuntersuchung aufgesucht hatten. Um andere Einflüsse auf die Thrombozytenfunktion zu vermeiden, wurden Frauen, die unter oraler Antikoagulationstherapie standen, die orale Kontrazeptiva und/oder nicht-steroidale antiinflammatorische Medikamente nahmen oder die eine chronische Erkrankung hatten, nicht in die Studie aufgenommen. Die Leukozytenzahl, die Thrombozytenzahl, der Neutrophilen Quotient und die MPV Werte wurden bei beiden Gruppen erhoben. Bei der Patientengruppe wurden zusätzlich die CRP Werte gemessen.ErgebnisseDie MPV Werte bei den Patientinnen waren niedriger als in der Kontrollgruppe (p < 0,001). Es bestand eine negative Korrelation zwischen der Thrombozytenzahl und den MPV Werten (p = 0,019, r = − 0,425). ROC Analysen ergaben, dass die MPV eine größere Fläche unter der Kurve hatte als die Neutrophilen Rate, oder die Leukozyten- beziehungsweise die Thrombozytenzahl (0,73, 0,64, 0,72 und 0,49 respektive).SchlussfolgerungDa das MPV bei Patientinnen mit Entzündungen im Beckenbereich signifikant erniedrigt war, kann dieser Parameter als ein zusätzlicher und im Vergleich zur Leukozytenzahl sogar wertvollerer Marker bei der Diagnose von Entzündungen im Beckenbereich dienen.

Assessment of Apoptotic Activity Dysregulation and Oxidative Stress in the Development of Epithelial Ovarian Cancer: A Case-Controlled Descriptive Analysis

Aim: In the present study, we aimed to assess whether oxidative stress and apoptotic activity play a role in the development of epithelial ovarian cancer (EOC). Methods: The study group included patients with EOC (n = 26) and benign ovarian tumour (BOT) (n = 25), while 30 healthy women were employed as a control group. Venous blood samples were drawn to evaluate oxidative stress parameters and serum M30/M65 antigen levels before surgery. In addition, blood samples were taken for the second time on postoperative day 8 to analyse whether the postoperative tumour load was decreased. Results: When the groups were assessed regarding oxidative stress, the highest values were detected in patients with EOC. Serum M30/M65 levels were found to be higher in patients with EOC when compared to the other groups (p < 0.001). A significant decrease was determined in the M30/M65 levels of serum samples taken on postoperative day 8 from the patients in the EOC and BOT groups (p < 0.001). Conclusion: Our results suggest that dysregulation of apoptotic activity could be effective in the development of ovarian tumoural tissue, whereas oxidative stress could be effective in malignant transformation.

The effects of lycopene on intestinal injury due to methotrexate in rats

Objective: The aim of this study was to investigate the effects of lycopene (Lyc) on methotrexate (Mtx)-induced intestinal damage in rats. Method: Twenty-eight male Sprague Dawley rats were divided into four equal groups: control, Mtx, Lyc, and Mtx-L. Control group: Rats were given only the vehicle. Lyc group: Rats were given Lyc (10 mg/kg) with corn oil by oral gavage for 10 days. Mtx group: Rats were injected intraperitoneally with a single dose of 20 mg/kg of Mtx and given corn oil by oral gavage. Mtx-L group: Rats were treated with Lyc (10 mg/kg) for 10 days after a single dose of Mtx (20 mg/kg). All of the rats were euthanized using terminal anesthesia, and the intestinal tissues were removed for histological examination and for pro-inflammatory cytokine measurement (tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1β)), total oxidative status (TOS), total antioxidant capacity (TAC), and oxidative stress index (OSI). Results: Mtx administration increased histopathological damage and increased TNF-α, IL-1β, TOS, TAC, and OSI levels in the small intestine tissues. Lyc therapy applied to the Mtx-L group provided significant improvement in all parameters of histopathological damage to the small intestine and significantly reduced the levels of IL-1β, TOS, and OSI in the intestinal tissues. Conclusions: The results of this study indicate that Lyc might be useful for protecting intestinal damage induced by Mtx in rats by reducing the increased oxidative stress and pro-inflammatory cytokine (IL-1β) levels.

Effects of β-Glucan on Colon Anastomotic Healing in Rats Given Preoperative Irradiation

ABSTRACT Background: Radiation therapy is an essential therapeutic modality in the management of a wide variety of tumors. We aimed to investigate the short-term effects of pelvic irradiation on the healing of colon anastomoses and to determine the potential protective effects of β-glucan in this situation. Material and Methods: Sixty Wistar albino rats were randomized into three experimental groups: a control group (n = 20), an irradiation (IR) group (n = 20), and an irradiation+β-glucan (IR+β-glucan) group (n = 20). Only segmental colonic resection and anastomosis were performed on the control group. The IR group underwent the same surgical procedure as the control group 5 days after pelvic irradiation. In the IR+β-glucan group, the same procedure was applied as in the IR group after β-glucan administration. The groups were subdivided into subgroups according to the date of euthanasia (third [n = 10] or seventh [n = 10] postoperative [PO] day), and anastomotic colonic segments were resected to evaluate bursting pressures and biochemical and histopathological parameters. Results: Bursting pressure values were significantly lower in the IR group (p < .001). Malondialdehyde (MDA) levels were significantly higher in the IR group, whereas β-glucan significantly decreased MDA levels on the third PO day (p < .001). Granulation tissue formation scores were significantly lower in the IR+β-glucan group compared with the control group and the IR group (p < .001). Conclusions: The results of this study indicate that irradiation has negative effects on the early healing of colon anastomoses. The administration of β-glucan ameliorates these unfavorable effects by altering bursting pressures and biochemical parameters.
