This study investigated the effect of prostaglandin E1 (PGE-1) treatment on the biochemical and histopathological changes in a model of nephropathy that was induced using renal microembolism in rats. Wistar rats were assigned to three groups: a control group (C, normal), a renal microembolism (RM) group, and a renal microembolism treated with PGE-1 (RM + PGE-1) group. The renal microembolism was induced by an arterial injection of polymethylmethacrylate microbeads into the remaining kidney of nephrectomized rats.

The aim of this study was to investigate some biochemical parameters of renal function and the vascular, glomerular, tubular, and interstitial manifestations in the progression of nephropathy induced by renal microembolism. Renal microembolism was induced by the arterial injection of polymethacrylate microspheres in the remnant kidney of nephrectomized rats. Animals 110-120 days old were randomly divided into three groups: the control group (C; normal), the nephrectomized group (S; nephrectomized that did not undergo renal microembolism), and the model group (M, nephrectomized animals that underwent renal arterial microembolism).

Fish oil (FO) is a natural source of omega-3 fatty acids, with well-established beneficial effects in inflammatory diseases when FO is orally administered. This study investigated the effects of a topically applied FO preparation (FOP) on phenol-induced ear edema and evaluated the percutaneous penetration of FOP in ear tissue. After applying phenol, groups of mice received FOP on the ear.

We report the case of a woman who was diagnosed with a pulmonary artery aneurysm that was caused by Behçet's disease. The patient was initially diagnosed with community-acquired pneumonia and then pulmonary thromboembolism and aneurysm of the right pulmonary artery segmental branch was confirmed. The initial treatment consisted of anticoagulant drugs.

Curcumin is the main curcuminoid found in turmeric rhizomes and is a strong candidate to formulate foodstuff with specific properties. Among various bioactive properties of curcumin, its antiinflammatory activity is remarkable; on the other hand, its low water solubility leads to low absorption. Thus, new formulations need to be developed to improve its efficacy, and encapsulation is a promising alternative strategy in this regard.

Article Synopsis
  • The study assessed the effectiveness of oral medications—indomethacin, ibuprofen, and paracetamol—for closing patent ductus arteriosus (PDA) in premature babies with significant health issues.
  • Indomethacin was found to be highly effective, closing the ductus in 87.5% of cases with a rapid recovery time, while ibuprofen and paracetamol were not effective on their own in these circumstances.
  • Even when ibuprofen or paracetamol were used first, some neonates could eventually successfully close the ductus with indomethacin later, though diuresis decreased in those treated with indomethacin.

Article Synopsis
  • - This study assessed the effects of anethole on inflammation and joint damage in rats with adjuvant-induced arthritis (AIA) by administering varying doses of anethole over 21 days.
  • - Results indicated that anethole significantly reduced paw swelling, decreased the number of inflammatory cells, and lowered cytokine and nitric oxide levels, with the highest dose (250 mg/kg) proving most effective.
  • - Histological analysis showed that anethole treatment led to less cartilage damage and inflammatory infiltration, suggesting it could be a promising treatment for inflammatory arthritis.

The hepatotoxicity induced by APAP is caused by the excessive production of N-acetyl-para-benzoquinone imine (NAPQI), which, when reacting with hepatic proteins proved to cause irreversible lesions. Associated with this process, an intense inflammatory process is also evidenced, characterized by the increased cell influx and production/release of inflammatory mediators. Trans anethole, an aromatic compounds has been showed anti-inflammatory efficacy by inhibit the cellular recruitment and synthesis/releases of many proinflammatory mediators such as prostaglandin (PGE), cytokines (TNF, IL-1) and nitrico oxide (NO).

Objective: To identify whether Canova medication changes TNF-α and IL-10 serum levels in mice infected with Trypanosoma cruzi Y strain.

Methods: Animals were divided into five groups: non-treated infected animals (I); benznidazole-treated infected animals (Bz; 100 mg/kg body weight, single daily dose by gavage); Canova medication (CM) treated infected animals (CM; 0.2 mL/animal, single daily dose by gavage); benznidazole- and Canova medication-treated infected animals with the above-mentioned dose (Bz+CM); and non-infected animals (C).

Article Synopsis
  • The study aimed to assess the impact of hydroethanolic yacon extract on high blood sugar levels in diabetic neonatal rats induced by streptozotocin (STZ).
  • After administering the extract for 14 days, results indicated a significant reduction in glucose levels in fed diabetic rats, while not affecting fasting glucose levels in either diabetic or normal rats.
  • Phytochemical analysis revealed beneficial compounds within the extract, suggesting it may enhance insulin sensitivity and reduce hyperglycemia without adverse effects on body weight or liver health.

This study was aimed to investigate the effect of Silymarin (SLM) on the hypertension state and the liver function changes induced by acetaminophen (APAP) in spontaneously hypertensive rat (SHR). Animals normotensive (N) or hypertensive (SHR) were treated or not with APAP (3 g/kg, oral) or previously treated with SLM. Twelve hours after APAP administration, plasmatic levels of liver function markers: alanine aminotransferase (ALT), aspartate aminotransferase (AST), glucose (GLU), gamma glutamyl transferase (γ-GT), and alkaline phosphatase (ALP) of all groups, were determined.

Fruits of Pterodon pubescens Benth have been used traditionally for the treatment of rheumatism, sore throat, and respiratory disorders, and also as anti-inflammatory, analgesic, depurative, tonic, and hypoglycemic agent. The study was aimed at evaluating the anti-inflammatory activity of the hexane fraction of an ethanolic extract of P. pubescens fruits.
