When selecting black fungus strains, it is important to pay attention to several key factors to ensure quality and successful cultivation. First, check the label on the bottle to make sure it matches the strain you are looking for, as using the wrong strain can lead to poor results. The cultivation period should not exceed two months, and the bacterial age should be between 30 to 40 days from the date of inoculation. Also, inspect the cap or stopper to ensure it is intact and not broken or missing. The mycelium should appear white, with thick, short, and dense hyphae. If you notice any green, yellow, red, blue, or gray-colored hyphae, this is a sign of contamination, and the strain should be discarded immediately. A high-purity strain will have a clean and healthy appearance without any signs of infection. Another important factor is the presence of a black ear base inside the bottle. Ideally, there should be some visible black ear base between the material and the bottle wall. A small amount is normal, but an excessive amount may indicate over-cultivation. While such strains might produce early and numerous ears after inoculation, they often fail to grow well and result in low yields. Check for sediment at the bottom of the bottle. A qualified strain should have little to no brown residue or only light brown gum. If there is a significant amount of brown liquid present, this indicates that the strain is old and should not be purchased. For wood-based sclerotinia strains, the surface should be covered with fine hyphae, and you should not see any sawdust particles. When handling the strain, it should form solid blocks rather than being loose, which is a sign of good quality and proper development. If the cultivation time is too short or the temperature was too low during growth, the mycelium may not fully cover the bottle or may not have penetrated the wood chips. In such cases, it’s best to continue cultivating the strain at the optimal temperature before using it for inoculation. Always store the strain in a clean, dry, and dark place. Before inoculation, never remove the tampon, and avoid reusing bottles to prevent contamination. Ensuring proper handling and storage is crucial to maintaining the viability and purity of the strain. Sildenafil is a selective inhibitor of cyclic guanosine monophosphate (CGMP) - specific phosphodiesterase 5 (PDE5) and an oral drug for the treatment of ED. The physiological mechanism of normal penile erection involves the release of nitric oxide (no) during sexual stimulation. Nitric oxide activates guanylate cyclase in the smooth muscle cells of the corpus cavernosum, which leads to the increase of cGMP level, resulting in the relaxation of the smooth muscle in the corpus cavernosum, the expansion of the cavernous sinus and the inflow of blood. Erectile dysfunction is mainly due to the dysfunction of smooth muscle relaxation of corpus cavernosum. Sildenafil has no direct relaxation effect on human sponges in vitro, but can enhance the effect of nitric oxide by inhibiting the decomposition of cGMP by PDE5 in sponges. Sildenafil can inhibit PDE5, increase cGMP level, relax smooth muscle of corpus cavernosum and let blood flow into corpus cavernosum. Studies have shown that erectile response increases with the increase of dose and plasma concentration, and the efficacy can last for 4 hours (but is weaker than that at 2 hours).
