For the baby to grow up healthily, expectant mothers will supplement various nutrients during pregnancy, DHA is one of a kind. DHA is a major element in the growth and maintenance of the nervous system cells, and is an important constituent of the brain and retina. It contains up to 20% in the human cerebral cortex, and the largest proportion in the retina of the eye, accounting for about 50%. Therefore, Fetal infant intelligence and vision development are crucial. Pregnant mothers can ingest DHA in the following ways: 1. Fish and seafood are important sources of DHA Fish and seafood are undoubtedly the best and most recommendable sources of DHA. Fish and seafood not only contain DHA, but also provide high-quality protein, vitamin A, iron, zinc, iodine and other nutrients, is an important part of the dietary structure during pregnancy. But to remind mothers that they are crabs, soft-shelled turtles, sharks, big-eared oysters, swordfish, square fish, and fish. Expectant mothers are not allowed to eat. Pregnant mothers who are allergic to seafood should also pay attention. 2. α-linolenic acid in edible oil In vivo, DHA can be synthesized and the raw material for the synthesis of DHA is α-linolenic acid. However, α-linolenic acid cannot be synthesized and must be provided by food. The most abundant foods containing α-linolenic acid are linseed oil and perilla seed oil, which are mostly in the range of 50% to 60%. Soybean oil and rapeseed oil also contain about 7% and 8% of α-linolenic acid, while peanut oil and corn oil contain very little α-linolenic acid. Alpha-linolenic acid is also rare in other foods. 3. DHA in pregnant women's milk powder Many pregnant mothers drink pregnant women's milk powder during pregnancy. The nutritional value of pregnant women's milk powder is better than that of ordinary milk. Because pregnant women's milk powder contains several special nutrients to meet the needs of pregnant women, milk powder is not added to all pregnant women's milk powder. Pregnant mother in the purchase is to see the nutritional formula table. 4. Specialized DHA nutritional supplements Theoretically, specialized DHA supplements such as fish oil and algae oil are the most reliable sources. However, we must choose a product with reliable quality and name. Experts from Jilin Guojian Maternity Hospital reminded that DHA is a nutrient that plays an important role in the growth and development of infants and young children and maintains normal human health. However, it requires a reasonable intake as other nutrients, and not so much. Mothers are best obtained through food. 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).
