Abstract

This study aimed to explore effectiveness and related mechanisms of Polygala crotalarioides in treating erectile dysfunction (ED). Hydrocortisone was used to establish a kidney-Yang deficiency ED rat model. Levels of triiodothyronine(T3), thyroxine(T4), testosterone(T), estradiol(E2) and expressions of RhoA, ROCK1, ROCK2 were determined. Immunofluorescence staining was used to detect CD34 in penile tissues. Compared with normal rats, T3, T4, T, E2 levels in serum of ED rat model were significantly reduced (P < 0.05), while RhoA, ROCK1, ROCK2 expressions were significantly higher (P < 0.05). High- and medium-dose of Polygala crotalarioides significantly attenuated erectile dysfunction, but low-doses of Polygala crotalarioides were ineffective. High and medium dose of Polygala crotalarioides and sildenafil significantly increased weight of ED rats compared to Model group (P < 0.05). T3, T4, E2, and T levels in low-dose, medium-dose, and high-dose of Polygala crotalarioides group were increased compared to Model group (P < 0.05). Compared with Model group, RhoA, ROCK1, and ROCK2 expressions in penile tissue of rats in low-, medium-, high-dose of Polygala crotalarioides group were reduced (P < 0.05). High-, medium-, and low-dose Polygala crotalarioides significantly increased CD34 compared with ED rat (P < 0.05). In conclusion, Polygala crotalarioides attenuated erectile dysfunction and improved thyroid and gonadal function by regulating Rho/ROCK pathway in kidney Yang-deficiency ED rat.

期刊介绍： Tissue and Cell is devoted to original research on the organization of cells, subcellular and extracellular components at all levels, including the grouping and interrelations of cells in tissues and organs. The journal encourages submission of ultrastructural studies that provide novel insights into structure, function and physiology of cells and tissues, in health and disease. Bioengineering and stem cells studies focused on the description of morphological and/or histological data are also welcomed. Studies investigating the effect of compounds and/or substances on structure of cells and tissues are generally outside the scope of this journal. For consideration, studies should contain a clear rationale on the use of (a) given substance(s), have a compelling morphological and structural focus and present novel incremental findings from previous literature.
