Naringin and trimetazidine improve baroreflex sensitivity and nucleus tractus solitarius electrical activity in renal ischemia-reperfusion injury

Arq. bras. cardiol; 117 (2), 2021
Resumo Fundamento: O núcleo do trato solitário (NTS) é uma área do cérebro que desempenha um papel fundamental na regulação renal e cardiovascular através dos impulsos dos barorreceptores. Objetivos: O objetivo deste estudo foi avaliar o efeito da Naringina (NAR) e trimetazidina (TMZ), isoladam...

In vitro and in vivo antioxidant potentials of the methanolic crude extract from Inula glomerata Oliv. & Hiern (Asteraceae) and Salacia kraussii (Harv) Harv (Celastraceae)

Reactive oxygen species are implicated in multiple pathological conditions including erectile dysfunction. This study evaluated the in vitro and in vivo antioxidant potential of the methanolic extracts of Inula glomerata and Salacia kraussii. The plant materials were pulverized and extracted with methan...

Investigation of the protective and therapeutic effects of β-aminoisobutyric acid (BAIBA) and Thymoquinone in the diabetic nephropathy

In this study, against streptozotocin (STZ) induced diapetic nephropathy (DN); it is aimed to investigate the use of thymoquinone (TQ) and β-aminoisobutyric acid (BAIBA) and to compare the effects of these agents. With random selection of 35 male rats, five groups (seven rats in each group) were consti...

The study of Yangyinyiqi mixture anti bleomycin-induced pulmonary fibrosis on rats by intervening matrix metalloproteinase-9 and tissue inhibitors of matrix metallopreoteinases-1

To investigate effectsof Yangyinyiqi Mixture on pulmonary fibrosis caused by bleomycin. SD ratswere divided randomly into: model group(distilled water,1 mL·0.1 kg-1), dexamethasone acetate group (dexamethasone acetate, the dosage was reduced gradually), low-dose group (Yangyinyiqi Mixture, 11 g·k...

Small bronchiolar histopathological changes related to prolonged diabetes

Int. j. morphol; 39 (2), 2021
SUMMARY: Diabetes mellitus increases the risk of developing chronic obstructive pulmonary disease (COPD). The small bronchiole is a prominent site of airflow obstruction that causes increased airway resistance in patients with the COPD. Therefore, the histological and ultrastructural changes in small bro...

Different expressions of AQP1 and AQP4 in hyponatremic rat brain

Int. j. morphol; 39 (1), 2021
SUMMARY: The expression of aquaporin-1 (AQP1) in choroid plexus and aquaporin-4 (AQP4) in astrocyte of the hippocampal formation (HF) was studied in the rat to determine the role of AQP1 and AQP4 in the pathophysiology of systemic hyponatremia (SH). SH was induced by coadministration of dextrose solution...
