Improvement of Na+-K+ ATPase Activity and Gene Expression Associated with Glomerular Ultrastructural Protection in Diabetic Nephropathy by Acacia senegal: Role of Oxidative Stress Disturbances

Int. j. morphol; 42 (1), 2024
SUMMARY: This study assessed the effects of Acacia Senegal (AS) combined with insulin on Na+/K+-ATPase (NKA) activity and mRNA expression, serum glucose, renal function, and oxidative stress in a rat model of diabetic nephropathy (DN). Sixty rats were equally divided into six groups: normal control, norm...

Alterations of serum biochemical parameters and tyrosine phosphorylation in kidney and liver of chronic stress-induced rats

Braz. j. biol; 84 (), 2024
Chronic stress (CS) can contribute to dysfunction in several organs including liver and kidney. This study was performed to investigate the changes in serum biochemistry, histological structure, as well as in localization of tyrosine phosphorylated proteins (TyrPho) and Heat shock protein 70 (Hsp-70) in ...

The Localization of R-Spondin1 and R-Spondin 3 Peptides in Rat Hypothalamus: An Immunohistochemical Study

Int. j. morphol; 41 (6), 2023
SUMMARY: The R-spondin protein family is a group of proteins that enhance Wnt/b-catenin signaling and have pleiotropic functions in stem cell growth and development. In the literature reviews, there is no histomorphological study showing the localization and distribution of R-spondins in different hypoth...

Acidic Environment Induces Pyroptosis of NLRP3 Inflammatory Vesicle-Mediated Nucleus Pulposus Cells Through Up-Regulation of POSTN Expression

Int. j. morphol; 41 (6), 2023
SUMMARY: Intervertebral disc degeneration (IVDD) is induced by nucleus pulposus (NP) dysfunction as a result of massive loss of NP cells. It has been reported that the acidic microenvironment of the intervertebral disc (IVD) can induce NP cell pyroptosis, and that up-regulation of periostin (POSTN) expre...

Time - sensitive effects of Zhuang medicated thread moxibustion on estrogen level in female perimenopausal model rats

The present study was conducted to ascertain the estrogenic effect of Zhuang Medicated Thread Moxibustion (ZMTM) and explore its time - sensitive impact on estradiol (E2) in female perimenopausal rats. 40 female rats were randomized into four gr oups: the control, model, ...

The Effects of White Tea (Camellia Sinensis) and Infliximab Against Cisplatin- Induced Testicular Damage via Oxidative Stress and Apoptosis

Int. j. morphol; 41 (5), 2023
SUMMARY: Cisplatin (Cis) is an important chemotherapeutic agent used in cancer treatment. Males exposed to Cis were reported to exhibit testicular toxicity. Cis-induced testicular toxicity is mediated by oxidative stress, inflammation, testosterone inhibition and apoptosis. Accordingly, this study was co...

Uncontrolled Diabetes with Underlying Structural Changes in the Atrioventricular Node

Int. j. morphol; 41 (4), 2023
SUMMARY: Diabetic cardiomyopathy, characterized by diabetes mellitus (DM) -induced cardiac muscular abnormalities, is a strong inducer of impaired cardiac contraction and arrhythmia. Atrioventricular block, a serious type of arrhythmia resulting from interruption of cardiac impulse conduction via the atr...

Altered Chief Cell Morphology in the Gastric Gland of Streptozotocin-Diabetic Rats

Int. j. morphol; 41 (4), 2023
SUMMARY: Diabetes mellitus (DM) is a metabolic disorder with rising incidences worldwide. Gastric symptoms of DM have been reported, including nausea, vomiting, bloating, and epigastric pain. Moreover, acute to chronic gastritis and atrophic gastritis occur in DM can affect the chief cells of the gastric...

The Role of MMP-9 in Regulating Degradation of the Splenic Microvascular Basement Membrane Induced by High Altitude Hypoxia

Int. j. morphol; 41 (4), 2023
SUMMARY: To investigate changes of MMP-9 in the rat spleen and hypoxia-induced microvascular basement membrane under high altitude hypoxia. Thirty male specific pathogen-free Sprague Dawley rats were randomly divided into control and hypoxia groups, with 15 rats in each group. The rats in the control gro...

Changes in the Craniomaxillofacial Growth and Development of Sprague Dawley Rats Subjected to Permanent Experimental Unilateral Nasal Obstruction

Int. j. morphol; 41 (4), 2023
SUMMARY: Breathing is considered a vital function dependent on factors such as adequate permeability of the nasal route, which is linked to physiological functions, intellectual processes, and craniofacial growth. The aim of this study was to determine the changes in the craniomaxillofacial growth and bo...
