Avaliação do perfil de citocinas séricas e óxido nítrico na hanseníase experimental murina

Hansen. int; 49 (), 2024
Introdução: a hanseníase é uma do-ença infecciosa crônica causada pelo Mycobacterium leprae (M. leprae), um para-sita intracelular obrigatório. Assim, a resis-tência do hospedeiro a esse patógeno depen-de da imunidade celular. O uso de modelos experimentais tem permitido...

Photobiomodulation effects on synovial morphology, iNOS gene, and protein expression in a model of acute inflammation

Acta cir. bras; 39 (), 2024
Purpose: To evaluate morphological aspects and inducible nitric oxide synthase (iNOS) gene and protein expression in a model of acute inflammation. Methods: Thirty-six female Wistar rats were assigned into three groups: control (saline, n = 12), sham (arthritis, n = 12), and PBM (arthritis and photobiomo...

Effects of curcumin supplementation on abdominal surgical wound healing

Acta cir. bras; 39 (), 2024
Purpose: To evaluate the effects of curcumin supplementation on abdominal surgical wound healing in rats using clinical, histological, and hematological parameters. Methods: Forty Wistar rats were randomly divided into two groups: the curcumin group, and the control group. The curcumin group received, i...

Ellagic acid protected the gingival tissue via fibroblast and epidermal growth factors in rats

Acta cir. bras; 39 (), 2024
Purpose: To investigate the effect of ellagic acid (EA) in gingival tissues injury in rats. Methods: Twenty rats were categorized into two groups. In burn group, an excisional wound area was created by removing a 4-mm diameter flap from the left molar region in the mucoperiosteal region of the gingiva. ...

Eucommia granules activate Wnt/β-catenin pathway, and improve oxidative stress, inflammation, and endothelial injury in preeclampsia rats

Acta cir. bras; 39 (), 2024
Purpose: Pre-eclampsia (PE) is a pregnancy-related complication. Eucommia is effective in the treatment of hypertensive disorders in pregnancy, but the specific effects and possible mechanisms of Eucommia granules (EG) in PE remain unknown. The aim of this study was to investigate the effects and possibl...

Temozolomide alleviates breast carcinoma via the inhibition of EGFR/ERK/ MMP-1 pathway with induction of apoptotic events

Acta cir. bras; 39 (), 2024
Purpose: To evaluate the chemotherapeutic activity of temozolomide counter to mammary carcinoma. Methods: In-vitro anticancer activity has been conducted on MCF7 cells, and mammary carcinoma has been induced in Wistar rats by introduction of 7, 12-Dimethylbenz(a)anthracene (DMBA), which was sustained for...

A microscope in your pocket: can smartphones be used to perform microsurgery?

Acta cir. bras; 39 (), 2024
Purpose: To evaluate the use of the latest generation smartphone camera in performing arterial microanastomosis in rats. Methods: Ten Wistar rats were divided into 2 groups and underwent anastomosis of the right carotid artery with the aid of magnification from a microscope (group M) and a smartphone cam...

Protective effects of hesperidin in gastric damage caused by experimental ischemia-reperfusion injury model in rats

Acta cir. bras; 39 (), 2024
Purpose: This study evaluated the protective effect of hesperidin on injury induced by gastric ischemia-reperfusion. Methods: Fifty male Sprague Dawley rats (250–300 g) were divided into five groups: control (C), sham (S), ischemia (I), ischemia-reperfusion (I/R) and hesperidin + ischemia-reperfusion (...

Antiosteoporosis effect of bryodulcosigenin on ovariectomy-induced osteoporosis in experimental rats

Acta cir. bras; 39 (), 2024
Purpose: Osteoporosis is a bone disease which commonly occurred in postmenopausal women. Almost 10 percent of world population and approximately 30% of women (postmenopausal) suffer from this disease. Alternative medicine has great success in the treatment of osteoporosis disease. Bryodulcosigenin, a pot...

Establishment and application of a new 4/6 infarct nephrectomy rat model for moderate chronic kidney disease

Acta cir. bras; 39 (), 2024
Purpose: To develop a new 4/6 infarct nephrectomy (INx) model rat mimicking moderate chronic kidney disease (CKD) and to evaluate its application. Methods: We modified the conventional 5/6 INx rat model to create the 4/6 INx model by ligating the renal artery branch to induce infarction of one-third of t...
