Flowers smell thanks to the phytoncides contained in essential oils. Phytoncides- special substances that are produced by the plants themselves to protect against diseases and insect pests. The term is derived from the Greek words fiton - plant and cedere - to kill. These protective substances inhibit the growth of bacteria and kill germs. At different types plant phytoncides have a different chemical composition.

It can be organic acids, essential oils (like marigolds). Most phytoncides are volatile and are released only by living plants. It is necessary to harvest herbs in a certain period in order to preserve phytoncides. After cutting, only a wild-growing peony retains the ability to produce phytoncides from flowers.

Essential oils act as regulators of transpiration - the evaporation of water by plants. Evaporating, essential oils surround the plant with an invisible cloud and protect it from overheating during the day and from hypothermia at night. Air mixed with essential oil vapor is less permeable to heat rays. Many have an aroma, but it is not always pink, there are roses with an atypical aroma for her, for example, hycinth, musky or violet.

The smells of some plants repel insects, even cattle bypass strong-smelling herbs. Due to their aroma, such plants are better preserved and win the struggle for existence.

Stomach cancer is one of the most common oncopathologies, the main danger of which is that it is rarely detected in our early stages. The fact is that this disease often does not have pronounced symptoms at the beginning of development, and the majority of the population simply does not pay due attention to preventive examinations. Therefore, stomach cancer is detected in the vast majority of cases at 3-4 stages.

In this case, you should not rely on domestic medicine, which relies on somewhat outdated treatment methods with insufficiently high efficiency and serious side effects. Even the best oncologists are limited both by outdated diagnostic and treatment hardware and by available pharmacological agents.

Therefore, in case of detection of stomach cancer, you should not tempt fate - it is better to raise funds for treatment in Israel.

Simple statistics - about 80% of patients diagnosed with stomach cancer (in some clinics, this figure reaches 90%), treated in Israeli clinics, demonstrate a five-year survival rate. Even the most severe cancer patients oncologists in this small country significantly prolong life and improve its quality.

Stomach cancer is a dangerous oncological disease, the treatment of which has a rather severe effect on the body. Even if it is possible to do without a complete or partial resection of the stomach, chemotherapy and radiation affect almost all organs and systems of the human body. If there was a significant surgical intervention (removal of the stomach partially or completely), the rehabilitation period can be especially difficult.

In Israeli clinics for the rehabilitation of patients after treatment of stomach cancer, special attention is given. After all, it depends on this period whether the cancer will recede forever, or a relapse will occur. In addition, aggressive treatments can have long-term side effects, and quite serious ones. The rehabilitation period under the supervision of Israeli doctors also allows minimizing their influence.

How is rehabilitation after stomach cancer in Israeli clinics?

Since each case of the disease is unique, the rehabilitation strategy, like the therapy strategy, is developed individually for each patient.

Patients diagnosed with stomach cancer usually need help to restore appetite, as well as general strengthening of the body, which often suffers from cachexia (exhaustion) due to cancer. In the case of surgical intervention, the elimination of pain syndrome is also required. Another important point is psychological rehabilitation.

Israeli clinics use the Fast Track rehabilitation technique. Its basis is intensive rehabilitation within the walls of a medical institution, which allows minimizing the time spent in the hospital walls. Therefore, the average rehabilitation course is only 10 to 14 days.

Stomach cancer is a severe and dangerous pathology of the digestive system, in which a special diet must be strictly observed. It is necessary to change approaches to nutrition immediately after the detection of the disease. But especially strict adherence to the diet will be required after surgery, especially if there has been a partial or complete resection.

Compliance with the diet is an important auxiliary factor on which the recovery of the patient depends. Failure to comply with the diet can significantly worsen the state of health.

Rules for eating with stomach cancer

In order to remove the load from the digestive system and stomach as much as possible, it is necessary:

• - observe the regimen of frequent meals in strictly metered small portions - from 5 to 6 times a day;
• - products must have a puree consistency: they must be wiped, ground or crushed in another way;
• - the time intervals between meals should be the same;
• - you can not eat excessively hot or, on the contrary, cold food - only warm;
• - dishes must be prepared right before consumption in the amount of one serving - food cannot be stored;
• - dishes must be boiled or steamed - all fried is strictly prohibited;
• - plant foods should prevail in the diet;
• - fatty foods are prohibited;
• - salt should be replaced with herbal seasonings.

Chemotherapy is one of the classic methods of treating oncopathologies, including stomach cancer. This technique is the use of cytostatic drugs. As a rule, it is included in the treatment protocol for gastric cancer as an adjunct to surgery, but can also be used as monotherapy.

Chemotherapy performed in Israeli clinics can significantly reduce the growth rate of neoplasia and the spread of cancer cells throughout the body. This technique can be used before surgery (in order to reduce the mass of the neoplasm), after surgery (to prevent recurrence by destroying the remaining cancer cells) or during surgery (HIPEC technique).

Types of chemotherapy in Israeli clinics

In Israeli clinics, systemic chemotherapy and HIPEC are most often used to treat gastric cancer.

Systemic chemotherapy is the treatment of a cancer patient by introducing cytostatics into the body according to a certain scheme. It can be done with oral medications, injections, pumps, or drips. Most often, chemotherapy is performed on an outpatient basis, in cycles repeated every few months (three cycles before surgery, three after). One cycle usually lasts about three weeks.

Oral medications (such as capicetabine) are taken by mouth as tablets on a schedule approved by your doctor. Intravenous infusions are carried out through cannulas, a PICC line implant, or a central catheter. Most often, both oral and intravenous administration of cytostatics are involved, since, as a rule, not one drug is prescribed, but a combination of them.

Hello everyone! I do not know what to do. Yesterday I watered my violets with diluted Schultz. Today it is impossible to enter the kitchen because of the unpleasant smell. What to do with it, will it disappear after the earthen clod dries out? I look forward to your advice.

Hello, Elena! Herself

Hello, Elena! I myself used this fertilizer myself before and was very pleased with it, with everything except the price, so now I already use others. Bad smell never had pots. I think you should make sure that it smells from them, maybe the source is different? If, nevertheless, the smell comes clearly from the pots, then look at the expiration date of the fertilizer, perhaps this is the case. What does the fertilizer itself smell like? What soil mix do you have? Maybe some kind of reaction went, which, to be honest, seems very strange to me, but probably possible. Besides, are you sure it's the real Schultz? How do the fiaks themselves feel? I don't know if the smell will go away long time who used this fertilizer, never encountered anything like it.

I watered the children with fertilizer

I watered the violets with fertilizer on the violets that stand on the window and the adult violets on the rack. The soil is the same for everyone - peat with agroperlite and vermiculite. And it's not the first time I've watered it like that. But now this stench has appeared. Took the kids out to the balcony. Date of manufacture 2011, everything is in order with the deadline. Schultz ordered in Russia in the online store "Fertilizers from Natalia".

For me, the worst thing is that if the smell does not disappear, then the husband will throw away all the violets. After all, we have two children and it is not known how the stench affects the body.

Lena, I also use

moderator

Lena, I also use Schultz and for a very long time. There was never any strange smell. Violets grow both on the wick and on regular watering. I don't even smell wet soil. Maybe the reason lies in something else. How do you breed him? Maybe more concentration?

It seems that you yourself provoked this smell. Any fertilizer is not kept diluted - it is diluted, spilled, and if there are leftovers, then, alas, it is necessary to pour it out. When I water my violets, I first dilute them with 1 liter of water, but personally I do it as indicated in the instructions, and the violets feel comfortable, no overfeeding. Of course, one liter is not enough for me to water the entire collection, so I plant the last portion judging by how many rosettes I have left to water, and if I need another half a liter of water, then I drip 3 drops, etc., that's all. Read the annotation of any fertilizer, stimulant, etc., everywhere it is indicated that it is IMPOSSIBLE to keep a diluted solution for more than a day !!! And you have a month, here not only the smell is possible, but poison for the violets (of course, let them endure this watering without loss). So calm down, but it is better to transplant violets as soon as possible, and then there will be no smell from violets in your apartment and you will also have no reason to part with violets. I think the more experienced ones will also advise you that it is better to transplant violets as soon as possible in order to get rid of the smell and the last such watering.

Natalia, baby violets I

Natalya, I have already transplanted the violets and brought them to the balcony. I also put flowering ones there, which I also watered with this solution. It doesn't get any nicer in the kitchen. The sun is in the windows - the smell is sharper. I already think that someone climbed under the suspended ceiling and died. There is a distinct musty smell. I had hamsters as a child and sometimes they would run away and never come back, and the neighbors who lived a few floors above us complained about bad smell in the apartment. Maybe this is the situation here. In the evening, my husband will come and sniff everything out. For the most important thing to prove that it is not from the flowers stink.

Elena sniffed everything.

Elena sniffed everything. The kids were at the window. The ones on the left smelled of earth. And the rest don't. I came to the conclusion that the damp earth absorbed the smell. It is above the violets under the stretch ceiling that it stinks strongly. Still, it's not a treat. Thank you all very much for your advice! Reassured me.

Hello, I'm sharing

Hello, here I share the reason for the appearance of a terrible smell.

2-3 times a year we buy carcass pork. this time they took half a carcass and it was very late to do something with it (2nd hour in the morning). My husband removed the bottom containers from the refrigerator. He put meat in the cold room. The blood entered the condensate drain and then into the evaporator. That's where it stinks!!!

Maybe someone will think that I am an alarmist. But when it comes to violets - to be or not to be - then all means are good! So I began to analyze, and ask all of you for advice.

That's how it happens!

Lenochka, hurrah! violets

Lenochka, hurrah! Violets are completely rehabilitated, I'm so happy for them! And if you threw them away, and then the cause of this trouble was found out? How to live with this injustice to violets?

That is why the death penalty was abolished in order to eliminate possible errors.

Here you see how

Here you can see how it all turned out. But it is good, of course, that the violets most likely did not suffer and will remain at your home. Apparently, really someone or something fell under stretch ceiling and gave you a lot of trouble and trouble. But for the future - do not leave the prepared solution, pour out the remnants. Good luck to you and lush flowering Your subordinates.

The reasons why all varieties of flowers have certain smells have been studied for many decades. There are several versions explaining this effect. The most common opinion is the influence of aroma on the attraction of insects that are actively involved in the pollination of flowers. Active participation in the pollination of flowers

The main reason for the occurrence of a particular aroma in a flower is the high content essential oils in petals. The set of elements differs depending on the variety of the plant, so the smell of different flowers is different from each other. Under the influence of air temperature or due to the moistening of the petals, essential oils begin the evaporation process. This process produces a characteristic aroma.

Particles of essential oils swirl around the plant for a long time. That is why people prone to allergic reactions try to avoid close contact with flowers. Otherwise, the smallest droplets of evaporating substances enter the respiratory tract and cause tears, runny nose or even suffocation.

Essential oils are found not only in petals, but also in leaves, shoots and even tree bark. As a result of the interaction of the existing components, different

People divide the smells of flowers into several categories - pleasant and unpleasant, sweet and tart. Some plants are very popular as a gift precisely because of their aroma. The function of smell is completely different.

The main purpose of fragrance for a flower is to attract the attention of insects. According to statistics, most flowering plants pollinated precisely thanks to winged helpers. Only a small number of them are able to self-pollinate or transmit their pollen through the air.

Essential oils become not only the causes of odors, but also play the role of reliable protection of the flower. The fact is that their particles for a long time remain around the bud in the form of a thin veil, which prevents excessive overheating or hypothermia of the petals. Volatile oils are complex chemical compounds with different compositions and properties.

The smell of some flowers changes during the day. There are plants that, for example, are distinguished by a particularly rich aroma only at night. This is due to the way of life necessary for pollination of insects.

Some flowers have a completely unattractive aroma. However, for a separate category of insects, it is the most effective beacon, and they take an unpleasant smell for products from their main diet.
