Acupuncture for infertility: is it an effective therapy? / 中国结合医学杂志

Acupuncture has been used to treat infertility extensively, including ovulatory dysfunction, in vitro fertilization and embryo transfer (IVF-ET), and male infertility. This review summarizes the recent studies which investigated the role of acupuncture in infertility. In conclusion, most of the existing studies suggest a positive effect of acupuncture in infertility treatment. Firstly, acupuncture may improve ovulation by modulating the central and peripheral nervous systems, the neuroendocrine and endocrine systems, the ovarian blood flow, and metabolism. Secondly, acupuncture can improve the outcome of IVF-ET, and the mechanisms may be related to the increased uterine blood flow, inhibited uterine motility, and the anesis of depression, anxiety and stress. Its effect on modulating immune function also suggests helpfulness in improving the outcome of IVF-ET. Finally, the studies suggest that acupuncture plays a positive role in male infertility, the mechanism of which is not yet clear. Even though a positive effect of acupuncture in infertility has been found, well-designed multi-center, prospective randomized controlled studies are still needed to provide more reliable and valid scientific evidence. Furthermore, it is urgent and necessary to clarify the mechanism of acupuncture for infertility.

Immunity to the 60kD heat shock proteins

A brief review on the role of the heat shock proteins (hsp), their common properties and possible consequences for early pregnancy development is described. The 60kD hsp plays an important role as immunogenic antigen of many microbial pathogens and possibly in postinfectious autoimmunity. The immune responce to hsp may cause pregnancy failure. The consequences of previous sensitization to microbial hsp and the effects of human autoantibodies to hsp, are demonstrated in a mouse embryo culture model.

O papel das Heat Shock Proteins no entendimento das infeccoes ginecologicas / The hole of heat shock proteins regards to gynecological infections

Os autores enfocam a importância da biologia molecular no avanço do entendimento dos processos fisiopatogênicos das doenças infecciosas. A Heat Shock Proteínas, tidas como importante mecanismo de defesa celular quando estas estäo submetidas ao estresse, säo descritas em detalhes, classificando-as e dando suas principais funçöes. Os efeitos destas proteínas no organismo humano foram considerados, mostrando-se como hipoteticamente o aumento de sua produçäo, poderia ajudar o indivíduo em determinadas circunstâncias, favorecendo o combate de algumas infecçöes e eventualmente, potencializando a recuperaçäo celular. As situaçöes desfavoráveis também foram destacadas, uma vez que mais esporadicamente, em alguns casos, pode haver possíveis reaçöes imunogênicas cruzadas, levando ao aparecimento de doenças crônicas
