Composition capable of achieving sun protection and preventing infection of mosquito-borne viruses such as Zika virus

Abstract

The invention belongs to the technical field of formulas of medicinal preparations, particularly relates to a composition capable of achieving sun protection and preventing infection of mosquito-borne viruses such as the Zika virus, and provides an external cream or ointment capable of achieving good sun protection and skin radiation damage repair effects and preventing invasion of mosquito-borne causative viruses such as the Dengue virus, the yellow fever virus, the West Nile virus, the Japanese B encephalitis virus and the Zika virus. Compared with an existing sun protection cream, natural antioxidants such as gossypol and ascorbyl fatty acid ester serve as main effective ingredients for sun protection and skin radiation damage repair and are assisted by glyzinc and zinc oxide, so that the external cream or ointment is safer and more effective; meanwhile, with the mosquito-repellent effect of mosquito repellent and the antiviral activity of gossypol, the risk that mosquito-borne causative viruses such as the Zika virus invade the human body through the skin in a mosquito biting mode is eliminated, and diseases spread by mosquito-borne viruses can be effectively prevented; the external cream or ointment has broad application prospects in the health field.

Description

technical field [0001] The invention belongs to the technical field of formulations of pharmaceutical preparations, in particular to a composition capable of sun protection and preventing mosquito-borne virus infection such as Zika. Background technique [0002] Skin, one of the most important organs of the human body, can block foreign invasion. The skin is the largest organ of the human body. It is located on the surface of the body and consists of three layers: the epidermis, the dermis, and the subcutaneous tissue. The skin covers the whole body, and it protects various tissues and organs in the body from physical, mechanical, chemical and pathogenic microorganisms. Although our skin has a strong ability to resist the stimulation of external adverse factors and rapid self-repair, if our skin is exposed to radiation beyond the tolerance limit and does not pay attention to strengthening protective measures, a series of skin damage will still occur. question.

AI Technical Summary

Problems solved by technology

[0010] Current research shows that the symptoms of most patients infected with Zika virus disease are not serious, and generally have fever, rash, conjunctivitis, muscle or joint pain, etc. There is epidemiological evidence that Zika virus infection may lead to "Guillain-Barré syndrome", and pregnant women may infect fetuses through amniotic fluid and placenta after infection, which may cause fetal nervous system development abnormalities, such as fetal microcephaly

Guillain-Barré syndrome and microcephaly are important reasons for the high international attention to Zika virus infection. These two complications have a poor prognosis and will bring a heavy burden to the patient's family

So far, humans do not have a vaccine for prevention or specific drugs for treatment of Zika virus infection
