    Background: Acute lung injury is respiratory failure due to various causes. Increased inflammatory and oxidative processes are recognized to play an essential role in the etiology of ARDS. Abelmoschus esculentus is an herbal product used to treat various diseases due to its anti-inflammatory and antioxidant effects. We aimed to investigate whether Abelmoschus esculentus has an effect on acute lung injury. Materials and Methods: In this experimental study, we used the ethanol extract of Abelmoschus esculentus seed. It divided forty male Wistar rats into five equal groups: 1) control, 2) Abelmoschus esculentus, 3) lipopolysaccharide, 4) lipopolysaccharide+Abelmoschus esculentus, and 5) lipopolysaccharide+ Abelmoschus esculentus +dexamethasone groups. Results: In the lipopolysaccharide group, native thiol, total thiol, IL-10, and IFN-? levels significantly changed. Abelmoschus esculentus was effective when used with dexamethasone in increasing native thiol and total thiol values (p=0.008 and p=0.004, respectively). On the other hand, when Abelmoschus esculentus was used alone, it significantly increased IL-10 levels and decreased IFN-? levels in the lipopolysaccharide group (p=0.025 and p<0.001, respectively). Additionally, improvements were noted in histological findings of alveolar congestion (p=0.006), intra-alveolar hemorrhage (p=0.006), and intra-alveolar macrophages (p=0.001). Conclusion: Abelmoschus esculentus, with its anti-inflammatory effect, may represent a new potential for treating acute lung injury. © 2023 NRITLD, National Research Institute of Tuberculosis and Lung Disease, Iran.

    Breath-holding Spells: Etiological Factors, Laboratory Findings, and Rates of Response to Iron Therapy
    (2021) Hanci, Fatma; Türay, Sevim; Tirink, Omer Faruk; Kabakuş, Nimet
    Aim: In this study, we aimed to investigate the etiological factors, electroencephalographic (EEG) findings, rates of response to iron therapy, and factors affecting response to iron therapy in children diagnosed with breath-holding spells (BHS). Methods: The study included 136 children aged 1 to 48 months who received iron therapy after a BHS diagnosis at our pediatric neurology clinic between November 2015 and No¬vember 2019. Patient medical records (physical examination, laboratory and EEG findings, medical history, and effectiveness of iron therapy) were reviewed retrospectively. Results: Of all patents, 81 (59.6%) exhibited partial response (partial remission) to iron therapy (50% decrease in BHS frequency), 52 (39%) responded completely (complete remission), and 2 were unresponsive. Comparison of the patients with complete and partial remission revealed a higher rate of complete remission in girls. In addition, patients with complete remission had higher levels of hemoglobin, MCV, and ferritin than those with partial remission. Complete remission rates were also higher in patients with normal EEG findings. Conclusion: BHS in childhood is a benign, recurring, and non-epileptic disorder and its differentiation from epilepsy is important. Children with BHS respond well to iron therapy, which can be recommended even if the serum iron and ferritin levels are normal.

    The effect of Anatolian syrup on experimentally induced acetaminophen and lipopolysaccharide associated acute kidney injury
    (2022) Düzcü, Selma Erdoğan; Çetinkaya, Ayhan; Efe, Muhammet; Kayiş, Seyit Ali; Bekdaş, Mervan; Yoldaş, Meyri Arzu; Tirink, Omer Faruk
    Background: Acute kidney injury develops as a result of various etiologies and pathological mechanisms, with a high mortality rate. This study aimed to investigate the efficacy of Anatolian syrup on histopathological variables in experimentally induced acetaminophen and lipopolysaccharide associated acute kidney injury. Methods: In this study, 5 groups were formed using 40 male Wistar albino rats (200- 220g, 2-4 months old), as follows: Sham, acetaminophen (1 g/kg intraperitoneal (ip)), 3) lipopolysaccharide (5 mg/kg ip), acetaminophen (1 g/kg ip) + Anatolian syrup (15 days orally), and lipopolysaccharide (5 mg/kg ip) + Anatolian syrup (15 days orally).Tubular atrophy, tubular dilatation, cytoplasmic vacuolization in tubular epithelial cells, tubular epithelial cell necrosis, interstitial inflammation, congestion, hemorrhage, glomerular damage and loss of brushy border were evaluated histopathologically semiquantitatively using scoring from 0 to 5. Results: In histopathological variables, tubular atrophy, tubular dilatation, cytoplasmic vacuolization, necrosis, congestion, hemorrhage, glomerular damage, and loss of brushy border were significantly reduced in the acetaminophen + Anatolian syrup group compared to the acetaminophen group and in the lipopolysaccharide + Anatolian syrup group compared to the lipopolysaccharide group (p<0.001). Conclusions: The Anatolian syrup was shown to protect histopathological variables in kidney damage caused by acetaminophen and lipopolysaccharide.
