Experiments were performed to compare the effects of cholesterol feeding in (a) control rabbits, (b) alloxan-diabetic rabbits, and (c) rabbits injected with alloxan while the pancreas was temporarily occluded from the circulation. The alloxan-diabetic rabbits consumed significantly higher quantities of cholesterol and food and had serum cholesterol and lipoprotein (S(f) 5-9 and S(f) 16-30) concentrations significantly increased over the control levels. They failed to show a commensurate increase in the degree of atherosclerosis. Rabbits in which the diabetogenic action of alloxan was prevented by temporary occlusion of the pancreas from the circulation during its administration developed grades of hypercholesterolemia, hyperlipoproteinemia, and atherosclerosis not significantly different from the controls. The results are interpreted as indicating that the effects of alloxan on tissues other than the pancreas do not protect against experimental atherosclerosis produced by cholesterol feeding.

Objective: This study aims to utilize bioinformatics and network pharmacology to identify the active components of Bushen Tiansui decoction (BSTSD) and elucidate its molecular mechanisms and targets in promoting delayed fracture healing.
Materials And Methods: Using various databases and tools, we identified 155 active compounds within BSTSD's herbal components. Key compounds such as eriodictyol and β-sitosterol were noted for their significant anti-inflammatory, antioxidant, and immunomodulatory effects, which are crucial for promoting fracture healing.

Cataracts are significant causes of blindness, closely linked to prolonged hypercholesterolemia. While saffron has the potential for eye health, its effects on lens lesions remain understudied. This study aimed to investigate the effect of saffron on the lens changes in atherosclerotic-induced New Zealand white rabbits (NZWR).

Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality globally, with oxidative stress playing a pivotal role in its progression. Free radicals produced via oxidative stress contribute to lipid peroxidation, leading to subsequent inflammatory responses, which then result in atherosclerosis. Antioxidants inhibit these harmful effects through their reducing ability, thereby preventing oxidative damage.

The importance of ferroptosis in the occurrence and progression of atherosclerosis is gradually being recognized. The stimulatory G protein α subunit (Gsα) plays a crucial role in the physiology of endothelial cells (ECs). Our previous study showed that endothelial Gsα could regulate angiogenesis and preserve endothelial permeability.
