The antioxidant and anti-inflammatory effects of Dex and MgSO ameliorated the detrimental effects of HCI-induced ALI. However, adverse effects on hemodynamics and lung damage were observed when the two drugs were administered together.

TurkeyCarvacrol prevents methotrexateinduced renal oxidative injury and renal damage in rats AbstractPurpose: e purpose of this study was to investigate the e ect of carvacrol (CAR) on methotrexate (MTX)-induced renal damage in rats.Methods: Twenty-four male rats were equally divided into three groups: group I, control treatment; group II, MTX-treated; and group III, MTX+CAR-treated. A single dose of CAR (73 mg/kg) was administered intraperitoneally to group III on the rst day of the experiment and a single dose of MTX (20 mg/kg) was administered intraperitoneally to groups II and III on the second day of the experiment. Blood samples and kidney tissue were obtained from each animal on day 8 for the measurement of malondialdehyde (MDA), total oxidant status (TOS), total antioxidant status (TAS), and oxidative stress index (OSI). Light microscopy was used for histopathological examination of kidney specimens.Results: MDA, TOS and OSI levels were signi cantly greater in the group receiving MTX alone relative to the control animals, while the TAS level was signi cantly reduced in the MTX group compared with the control group. e administration of CAR was associated with signi cantly decreased MDA, TOS, and OSI levels and increased TAS levels relative to the rats treated with MTX alone. Animals treated with CAR exhibited decreased tubular degeneration and architectural impairment relative to animals treated with MTX alone; however, the di erence in histological scores did not meet the threshold of statistical signi cance. e folic acid antagonist methotrexate (MTX) is used clinically to inhibit the synthesis of purines and pyrimidines [1]. MTX is commonly used at high doses to limit the growth of malignancies, but may also be used at low doses in in ammatory diseases, including psoriasis and rheumatoid arthritis, to inhibit the proliferation of in ammatory leukocytes [2][3][4]. MTX remains an essential component of modern clinical therapy for acute lymphoblastic leukemia and is the primary treatment for malignant gestational trophoblastic disease [5]. In addition to anti-proliferative activity, MTX has antiin ammatory and immunomodulatory properties; however, cytotoxic e ects and other side e ects limit the e cacy of MTX as an anti-in ammatory. Signi cant side e ects of MTX have been described in several organ systems. In particular, MTX has a detrimental e ect on kidney function [6]; however, the mechanism of MTX-induced toxicity remains unclear. More than 90% of MTX is ltered by the kidneys [7] and MTX treatment is known to cause renal failure at high doses [8]. Renal impairment can result in altered metabolism of MTX, delayed drug excretion and, subsequently, systemic toxicity. e toxic e ects of MTX are typically treated through hydration and alkalinization of the patient; however, these methods are insu cient to prevent all instances of MTX toxicity. Reactive oxygen species (ROS) have been implicated in the pathogenesis of MTX-induced renal damage [9,10]. MTX produces free oxygen radicals, resulting in enhanced li...

BackgroundThis study was designed to evaluate the effects of carvacrol (CRV) and pomegranate extract (PE) on methotrexate (MTX)-induced lung injury in rats.Material/MethodsA total of 32 male rats were subdivided into 4 groups: control (group I), MTX treated (group II), MTX+CRV treated (group III), and MTX+PE treated (group IV). A single dose of 73 mg/kg CRV was administered intraperitoneally to rats in group III on Day 1 of the investigation. To group IV, a dose of 225 mg/kg of PE was administered via orogastric gavage once daily over 7 days. A single dose of 20 mg/kg of MTX was given intraperitoneally to groups II, III, and IV on Day 2. The total duration of experiment was 8 days. Malondialdehyde (MDA), total oxidant status (TOS), total antioxidant capacity (TAC), and oxidative stress index (OSI) were measured from rat lung tissues and cardiac blood samples.ResultsSerum and lung specimen analyses demonstrated that MDA, TOS, and OSI levels were significantly greater in group II relative to controls. Conversely, the TAC level was significantly reduced in group II when compared to the control group. Pre-administering either CRV or PE was associated with decreased MDA, TOS, and OSI levels and increased TAC levels compared to rats treated with MTX alone. Histopathological examination revealed that lung injury was less severe in group III and IV relative to group II.ConclusionsMTX treatment results in rat lung oxidative damage that is partially counteracted by pretreatment with either CRV or PE.

Purpose:Bladder tumors are rare in children and adolescents. For this reason, the diagnosis is sometimes delayed in pediatric patients. We aimed to describe the diagnosis, treatment, and follow-up methods of bladder urothelial neoplasms in children and adolescents.Materials and Methods:We carried out a retrospective multicenter study involving patients who were treated between 2008 and 2014. Eleven patients aged younger than 18 years were enrolled in the study. In all the patients, a bladder tumor was diagnosed using ultrasonography and was treated through transurethral resection of the bladder (TURBT).Results:Nine of the 11 patients (82%) were admitted with gross hematuria. The average delay in diagnosis was 3 months (range, 0–16 months) until the ultrasonographic diagnosis was performed from the first episodes of macroscopic hematuria. A single exophytic tumor (1–4cm) was present in each patient. The pathology of all patients was reported as superficial urothelial neoplasm: two with papilloma, one with papillary urothelial neoplasm of low malignant potential (PUNLMP), four with low grade pTa, and four with low grade pT1. No recurrence was observed during regular cystoscopic and ultrasonographic follow-up.Conclusions:Regardless of the presence of hematuria, bladder tumors in children are usually not considered because urothelial carcinoma in this population is extremely rare, which causes a delay in diagnosis. Fortunately, the disease has a good prognosis and recurrences are infrequent. Cystoscopy may be unnecessary in the follow-up of children with bladder tumors. We believe that ultrasonography is sufficient in follow-up.

Infantile fibrosarcoma is a very rare soft tissue tumor that originates most commonly in the body and extremities. We present a neonate with an infantile fibrosarcoma that originated in the ileocecal region and was detected incidentally without symptoms. This is the first case of fibrosarcoma reported in the ileocecal region.
