Demonstrated suppressive effect on five viruses that cause summer cold and measles

Summer colds, such as pool fever, herpangina, and hand-foot-and-mouth disease, are a viral infection that spreads from the rainy season to the summer, especially in children whose immunity is weaker than adults. Adenovirus, enterovirus, echovirus, and coxsackie virus have been identified as the four main causes of these summer colds. In addition, measles that spread from spring to summer has a very strong infectivity due to the measles virus.

Winter cold / flu

Colds and the flu are both caused by viruses. It has been demonstrated that the streamer technology has an inhibitory effect on the virus and also on the RS virus.

There are three types of influenza virus: type A, type B and type C. Among them, type A has particularly strong symptoms such as high fever. It is so infectious that it spreads quickly and is therefore called a threat flu virus.

0157

It has been proven that the active species produced by the streamer technology decompose and neutralize O157 when it comes into contact with O157, which causes food poisoning. Furthermore, this time, it was proved that the suppression performance was increased 18 times by operating two streamer units.

O157 was irradiated with a streamer for 1, 2, 3, 4, and 8 hours, and the cells were inoculated into the cultured cells, and the residual state of O157 due to the difference in the time of irradiation with the streamer was observed.

O157, both toxin and infectious

O157 produces a strong toxin called verotoxin, which causes abdominal pain, bleeding diarrhea, and vomiting. It is one of the most dangerous bacteria that can become severe and kill lives when infected by infants and the elderly. In addition, O157 is highly infectious, and general food poisoning does not occur unless about 1 million bacteria enter, whereas O157 causes food poisoning with as little as about 100 bacteria.

Norovirus

It has been proven that the active species produced by streamer technology can degrade and neutralize norovirus when it comes into contact with norovirus, which causes food poisoning. Furthermore, this time, it was proved that the suppression performance was approximately doubled by operating two streamer units.

The survival rate of norovirus 4 hours after irradiation of the streamer was 1.3% for one unit operation and 0.6% for two units operation, confirming about twice the suppression performance.

Test method

Use mouse norovirus [mouse norovirus] ① A virus belonging to the genus Norovirus of the Caliciviridae family (single-stranded RNA virus, plus sense, no envelope) ② A closely related virus belonging to the same virus genus as the human norovirus May be used as a substitute for virus. 3) Increase in mouse macrophage-like tumor cell line RAW264 cells. ● MNV-S7 strain (Toya et al., Genbank accession no. AB435515) was used in this experiment. (Purchased from cell bank). D-MEM / Ham's F-12 (containing phenol red, HEPES, sodium pyruvate) was used as the culture solution.

Beware of winter! Food poisoning due to norovirus

Bacterial food poisoning is more common in summer, when it is easy for bacteria to multiply, but viral food poisoning increases in winter, as viruses prefer cold and dry environments. Among them, food poisoning due to norovirus is overwhelmingly common. Norovirus is highly infectious and often spreads at a stretch, resulting in more outbreaks and patients than in summer. Norovirus accounts for more than half of the annual number of food poisoning cases.

Reason for unpleasant odor from inside air conditioner

Due to the structure of the air conditioner that operates while inhaling the air in the room, dirt and dust easily accumulate inside the air conditioner, and there is an environment where mold and the like are easily generated by condensation. Dust is a nutrient source of mold, and the fungi that feed on the mold cause the odor-causing bacteria inside the air conditioner.
In order to prevent odor-causing bacteria inside the air conditioner, the filters and flaps are frequently cleaned, and after cooling operation, the air is blown for about one hour to dry the inside of the air conditioner. Let's take measures that we can do.

Fresh dry smell of laundry

It is known that Moraxella bacteria are the causative bacteria of unpleasant raw odor that occurs when clothes are dried in the room. It was confirmed that the streamer technology decomposes and removes the bacteria that cause this dry odor.

Test method

A sample containing 2 ml of the test bacterial solution in a Petri dish (φ60 mm) was used as a sample, and allowed to stand still in a streamer generator. Check. The streamer generator and test bacteria are provided by Daikin. The number of measurements was three.

In order to control the unpleasant odour, you should dry it within 5 hours!

The most important thing to avoid generating unpleasant odour is "time from washing to drying." Moraxella bacteria grow explosively after about 5 hours, so if they can be dried within 5 hours, fresh odour can be suppressed to some extent.
So what I want to hold down is the trick of drying the room. First, it is important to dry in a well-ventilated place. I think that there are many people hanging on the curtain rails, but it is the most unfavorable place because there is a lot of moisture near the windows and many germs.
And one way to dry it. You can quickly dry the clothes by hanging the longest thing on the outside of the clothes hanger and the short thing in the middle, "Arch drying", or by hanging only the sleeves of the long-sleeved shirt on another hanger. . Considering the growth of bacteria, it is recommended to use a dehumidifier or air conditioner with an air purifying function. This way, you can control the dry odour with a little effort.

16 types of pollen

Streamer technology has been confirmed to suppress 16 types of pollen (cedar, cypress, rice, Japanese pampas grass, hosomugi, oooagaeri, harugaya, kamogaya, Japanese red pine, black pine, mugwort, S. kawadachi, ragweed, kanagura, birch, ginkgo). 

In fact, pollen are found throughout the year

Spring may have the image of a pollen season, but this is due to the fact that the most susceptible cedar pollen begins to fly in early spring. However, in practice, from Hokkaido to Okinawa, a wide variety of plants emit pollen throughout the year, so it is important to provide care throughout the year. First of all, let's grasp the type of pollen and the season of scattering to help prevent it.
Also, depending on the weather and the region, pollen scattering peaks occur twice a day. The first peak is from morning to afternoon. This is because pollen scattered from the mountains in the early morning flows into urban areas. And the second peak is evening. When the temperature drops, convection of air occurs, causing pollen to fall or pollen that had fallen on the ground to fly up. Both are during the time when there are many human movements, so be sure to take measures to prevent pollen such as wearing a mask.

Perennial allergy

Streamer technology has been shown to break down house dust (mite dust and carcasses) that can cause perennial allergies. In addition, when allergic allergy and seasonal allergy are combined, the allergic symptoms worsen or are more likely to occur, but it was also found that this causative substance is decomposed at the same time.

Demonstration at Yamagata University under the supervision of Professor Shirasawa of Tohoku Bunka Gakuen University

Test method

Irradiation of streamer plasma was applied to the mite of Dermatophagoides pteronyssinus as a typical causative agent of perennial allergy and Japanese cedar pollen antigen as a causal agent of seasonal allergy. Allergen activity before and after irradiation is measured by ELISA (a method of detecting and quantifying the binding of an allergen to an antibody using an enzymatic reaction), and the inactivation rate (rate of losing the ability to cause allergy) is measured. 

Allergic rhinitis is the number one disease that reduces work productivity

There are many factors that reduce productivity at work, such as stress and migraines, but research has shown that the most productive factor is allergic rhinitis. If allergic allergies due to mites (funnels / carcasses) and seasonal allergies due to pollen overlap, allergic symptoms will worsen, and further decline in productivity is expected.

Relationship between mold and mite and allergy

Both mold and ticks prefer a humid environment, so they breed in humid periods. Moreover, since the mite in the room is fed by mold, ticks are more likely to occur in places where mold breeds. These molds and mite dungs ​​and carcasses can cause a variety of allergic symptoms, such as atopic dermatitis, asthma, rhinitis, and itchy eyes, by contacting or inhaling the skin.
