Abstract:

It has been shown that some of the mycotic infections especially systemic mycoses show increased male susceptibility and some steroids have been known to influence the immune response. Researchers found that some fungi including yeasts use "message molecules" including hormones to elicit certain responses, especially in the sexual cycle, but until recently no evidence was available to link specific hormonal evidence to this pronounced sex ratio. More evidence needed to demonstrate that a steroid (s) might in some manner influence the pathogenicity of the fungus in vivo. Therefore, the aim of this review paper is to shed some light on this subject along with effort to make mycologists more aware of this research as a stimulus for the explore of new ideas and design further research in this area of medical mycology.

Systemic Mycoses

I was particularly hopeful that a more illuminating discussion of the application of lasers to medicine would be given in Chapter 6. The topics involved are: Eye Surgery (primarily welding of detached retinas), Lasers in Dentistry, and Lasers and Skin (treatment of skin cancers). There are also brief sections on "Protecting the Eye" and use of lasers in "Medical and Biological Research." Here a...

Antifungal Susceptibility Testing for Systemic Mycoses

Introduction Compared to antibacterial drugs, antimicrobial agents available for treatment of invasive fungal infections are sparse. Amphotericin B (polyene) was the first drug introduced in the 1950s, followed by flucytosine (pyrimidine) in the 1970s, and first-generations azoles (fluconazole, itraconazole) in the 1990s. Triazoles (voriconazole, posaconalzole) and echinocandins (caspofungin, m...

Guanyl nucleotides modulate binding to steroid receptors in neuronal membranes.

The recently characterized corticosteroid receptor on amphibian neuronal membranes appears to mediate rapid, stress-induced changes in male reproductive behaviors. Because the transduction mechanisms associated with this receptor are unknown, we performed radioligand binding studies to determine whether this steroid receptor is negatively modulated by guanyl nucleotides. The binding of [3H]cort...

Steroid receptors in meningiomas.

Cytosolic estrogen (ER), progesterone (PR), androgen (AR) and glucocorticoid receptors (GR) were evaluated in 10 meningiomas using a dextran charcoal coated method. We consider as positive specific receptor values greater than or equal to 10 fMol/mg protein. In this study 20% of the meningiomas contained very low titers of specific ER. PR was detectable in 90% of the tumors, at high levels. The...

Immunotherapy in patients with systemic mycoses: a promising adjunct.

Evidence from several in vitro and animal model studies suggests a modulatory role of haemopoietic, T(H)1 and T(H)2 cytokines in host defence against fungi, and highlights their potential utility as adjunctive therapy for management of systemic mycoses (SM). However, there are limited clinical data to support the use of cytokines in prevention and treatment of SM. Thus, at present no adjunctive...
