Purpose: Male infertility is a serious problem, and its prevalence has been increasing. Therefore, we investigated the safety of a new herbal formula and its effects on sperm quality.
Materials And Methods: An in vitro cytotoxicity test in TM3 Leydig cells was performed to evaluate cell viability after administration of five types of herbs separately and of a new herbal formula containing these five. An in vivo test in male mice was performed to evaluate the influence of the new herbal formula on the reproductive organs and sperm quality. After the 8- and 28-day oral administration of the new herbal formula, the weights of the reproductive organs were measured and the sperm count and motility were evaluated.
Results: In the in vitro cytotoxicity test, less than 80% cell viability at concentrations of 500 mg/L and 1,000 mg/L of Rubus coreanus Miquel and Cuscuta chinensis Lam was observed. However, more than 80% cell viability was observed at all the tested concentrations of the new herbal formula. After the 8- and 28-day oral administration, there were no considerable changes in body weight. The weights of the testes, epididymis, and seminal vesicles after the 8- and 28-day oral administration were similar to those of the control. The sperm count and activity were significantly improved compared with those of the control group at 8 and 28 days after 100, 200, and 400 mg of oral administration.
Conclusions: The safety of the new formula and its positive effect on the sperm quality were observed after the oral administration of the formula.

Blood stasis-heat syndrome is one of the common syndromes of ischemic stroke, which is manifested as syndromes of blood stasis and heat during the pathological progression of patients with ischemic stroke, but there is a lack of systematic research on its biological essence. Thromboinflammation reaction is a newly proposed pathological mechanism highly associated with thrombosis and inflammatory reaction, and it refers to the fact that under the mediation of von Willebrand factor(vWF) and the kallikrein-kinin system, thrombosis and inflammatory reaction interact with each other. Activation of T cells and neutrophils further aggravates thrombosis and worsens the pathological progression of ischemic stroke.

This study aimed to investigate the potential mechanism and the compatibility significance of Tanyu Tongzhi Formula in treating atherosclerosis(AS) in mice based on the transforming growth factor-β(TGF-β)/Smad2/3 signaling pathway. Eight C57BL/6J mice were as assigned to a normal control group and fed a regular diet, while 35 ApoE~(-/-) mice of the same strain were fed a high-fat diet for 8 weeks to establish an AS model. The model mice were randomly divided into a model group, a Tanyu Tongzhi group(18.
