Felodipine is a calcium channel blocker with antioxidant and anti-inflammatory properties.Researchers have stated that oxidative stress and inflammation also play a role in the pathophysiology of gastric ulcers caused by nonsteroidal anti-inflammatory drugs. The aim of this study was to investigate the antiulcer effect of felodipine on indomethacin-induced gastric ulcers in Wistar rats and compare it with that of famotidine. The antiulcer activities of felodipine (5 mg/kg) and famotidine were investigated biochemically and macroscopically in animals treated with felodipine (5 mg/kg) and famotidine in combination with indomethacin. The results were compared with those of the healthy control group and the group administered indomethacin alone. It was observed that felodipine suppressed the indomethacin-induced malondialdehyde increase (p< 0.001); reduced the decrease in total glutathione amount (p< 0.001), reduced the decrease superoxide dismutase (p< 0.001), and catalase activities (p< 0.001); and significantly inhibited ulcers (p< 0.001) at the tested dose compared with indomethacin alone. Felodipine at a dose of 5 mg/kg reduced the indomethacin-induced decrease in cyclooxygenase-1 activity (p< 0.001) but did not cause a significant reduction in the decrease in cyclooxygenase-2 activity. The antiulcer efficacy of felodipine was demonstrated in this experimental model. These data suggest that felodipine may be useful in the treatment of nonsteroidal anti-inflammatory drug-induced gastric injury.

Aim: This study aimed to evaluate the relationship between uric acid variability and cardiovascular risk factors, primarily albuminuria and blood lipids, in patients with diabetes. Material and Method: Data from 174 patients with diabetes whose biochemical parameters were examined at least once a year were collected over the course of five years of regular follow-up. The five-year averages and standard deviations of each parameter for each person were calculated. The adjusted standard deviation for each parameter was considered as a measure of individual variability. The patients were divided into two groups according to the median of the mean uric acid and the median of the adjusted standard deviation of uric acid. Results: Between low and high uric acid variability groups, while there was no statistically significant difference for the mean values of following parameters, there was a difference in the variability of glucose (p=0.010), HbA1c (p=0.016), total cholesterol (p=0.008), and low-density lipoprotein-cholesterol (p=0.002). Moreover, there was difference in mean albuminuria (p= 0.019), albuminuria variability (p=0.040), mean triglyceride (p=0.011), triglyceride variability (p=0.018), and mean high-density lipoprotein-cholesterol cholesterol (p=0.008). Conclusion: Clinicians should pay attention to uric acid variability in addition to basal uric acid levels since it is associated with albuminuria, an atherogenic lipid profile, renal functions, and the variability of these parameters, independent of HbA1c and glucose levels.

Amaç: Bu çalışmada, obez hastalarda retinal mikrovasküler yapısında meydana gelen değişiklikleri değerlendirmeyi ve bu değişikliklerin klinik özelliklerle ilişkisini belirlemeyi amaçladık. Gereç ve Yöntemler: Tüm katılımcılarda kolesterol, açlık kan şekeri, açlık insülini,CRP ve HbA1C düzeylerini içeren biyokimyasal incelemeler yapıldı. Plazma aterojenik indeksi(AI) plazma trigliserid (TG) düzeyinin yüksek yoğunluklu lipoprotein (HDL) düzeyine oranının logaritması [log (TG/HDL-K)] olarak hesaplandı. Vücut Kitle İndeksi (VKİ) ≤25 kg/m2 olan hastalar kontrol grubuna dahil edildi. Obez hastalar VKİ'lerine göre üç gruba ayrıldı: grup 1 (VKİ: 30-34,99 kg/m2), grup 2 (VKİ: 35-39.99 kg/m2) ve grup 3 (VKİ ≥ 40 kg/m2) . Optik koherens tomografi anjiografi (OKT-A) ile foveal avasküler zon (FAZ), makulada yüzeyel ve derin kapiller pleksusun damar dansitesi (VD) ile radial peripapiller kapiller pleksus VD ölçüldü. Bulgular: Çalışmaya 27 kontrol ve 83 obez hasta olmak üzere toplam 110 hasta dahil edildi. Kontrol vakalarına kıyasla obez hastalarda HbA1C, açlık insülini, HOMA-IR, C-reaktif protein ve AI seviyeleri anlamlı derecede yüksekti. Obez hastalarda retinanın yüzeyel (p=0,003) ve derin (p=0,001)VD'leri anlamlı olarak azaldı ve FAZ anlamlı olarak arttı (p=0,032). Klinik özellikler ile OKT-A bulguları arasında yapılan korelasyon analizinde yüzeyel ve derin VD'ler yaş, VKİ, HbA1C ve AI ile ters orantılıydı. Sonuç: Obez hastalarda retina yüzeyel ve derin VD'leri azalmıştı ve retinal VD'ler ile yaş, VKI, HbA1C ve AI arasında ters bir ilişki vardı.
