On May, 29 director of the St.-Petersburg Biomedical center professor Andrey Kozlov participating in the 16-th international conference AIDS, Cancer and Public health informed, that the work on creation of the Russian HIV vaccine have turned the corner of clinical tests.
Scientists from Moscow, Saint Petersburg and Novosibirsk managed to develop antidote against virulent infection by a method of genetic engineering. Kozlov informed that in Saint Petersburg with the assistance of large American university centers and the USA National institute of health is created the necessary structure for clinical tests of vaccine.
This structure has everything necessary for tests: genic-virologic laboratories, capacities for production of necessary quantities of test samples of a preparation, and volunteers from risk groups.
However Professor Kozlov has noted that it is too early to talk about an unconditional victory over AIDS. In his opinion, development of effective means of struggle against this disease can take not one year.
As to the state financing of the further works, discussion of this question will begin this June.

The antibiotic used for treatment of serious infections, resistant to other antibiotics, can cause even more grave condition, a thrombocytopenia.
The main point of a condition is that together with massive not stopped bleedings, it causes reduction of thrombocytes, which help to stop bleedings.
Vancomycin is an antibiotic which is used for about 30 years and which is irreplaceable at treatment of serious infections which are too tough for other antibiotics. However, together with strong antimicrobial action it is able to cause serious side effects, such as hearing loss and damage of kidneys.
Senior researcher of Тhe Blood Center of Wisconsin’s Blood Research Institute, Wisconsin, the USA, Doctor Richard Aster, considers nevertheless, that results of work should not be an obstacle to an assignment of an antibiotic when it is the last hope in struggle against an infection.
Before the assignment of a preparation experts advise to take consultation with hematologist and to discuss with him an opportunity of the preparation assignment.

Surgeons of the Cedar-Sinai Medical center in Los Angeles had to transplant to the patient the “used” donor heart, which first owner died soon after the surgery.
The second recipient, whose name is not informed, had been in a waiting list of donor organs for some years. According to doctors, because of extraordinary big constitution of this patient, chances to find another suitable for him transplant were very insignificant. At the same time, the state of the man, who had syndrome of noncompact myocardium, worsened quickly and demanded immediate heart transplantation.
As informed in interview to Reuters director of Cedar-Sinai transplantation division doctor Lawrence S. C. Czer, the first recipient had lived with the donor heart about one week, and the reasons of his death had no relation to the operation.
According to Czer, the second heart transplantation was complicated by many factors. Two long periods of blood supply absence during both operations considerably increased risk of a unsuccessful outcome.
Nevertheless, the patient was successfully operated and quickly recovers. Now he has left the medical center, graft rejection is not observed.

Experts of the American company have created the superoxidized water which should replace medical products of healing, disinfectant and restoring action.
Development belongs to Oculus company. A key element of special water is a component named Microcin, which represents lattices from oxychloride ions - the charged molecules, which block a number of microbes.
New development is effective at the preventive of diabetes, an ulcer and thrombus. Also new water kills only alien micro-bodies and sick cells, and healthy cells are interconnected, therefore this method is harmless for them.
Experts of the company comment, that usual water also contains ions, hypochlorites and other elements, however their contents in it is not enough.
Now experts assure that the superoxidized water is able to kill 10 kinds of bacteria which are on one ot the other way connected to various diseases.
The company plans to present its invention at the International biomedical conference in Monte Carlo.

Ministry of Health warns people about the necessity to care for the health during the hot summer days - not to abuse solar bathing, do not drink cold beer, but to use mint broth in the evening.
According to long-term observations of physicians, with the coming summer season, especially in hot days, cases of serious diseases become more frequent, often with lethal consequences, because of unreasoned actions of people. High-risk group includes older persons, children and also those who suffer cardiovascular and lung diseases.
Therefore Ministry of Health recommends to avoid drinking cold beer in hot weather as it increases load on the heart, and offers mint broth in the evening, as it is known for its positive influence on the general state of an organism, nervous system and vessels, in particular.

Women who refuse to eat dairy products in order to grow thin are mistaken. American researchers have found out that calcium which is in a plenty contained in milk, helps to reduce weight and to fix the received results.
During the medical observation it was found out, that loss of weight directly depends on amount of calcium from milk. Women who consumed more dairy products and received calcium from milk within two years have lost more superfluous kilogrammes and more fat.
In opinion of one of the research authors, doctor Dorothy Tigarden, these data can be used to convince young women to eat well. In the age of 18-31 year when many start to grow stout, they need to be explained, that calcium not only strengthens bones, but also helps lose weight.
Scientists cannot explain the mechanism of calcium action yet. However they notice that these data corresponds to the information about calcium, obtained earlier.
At the moment American doctors consider, that a daily diet of young women should contain not less than thousand milligrams of calcium counting on two thousand calories.

Computer tomography treatment can lead to development of cancer diseases at patients.
The American roentgenologists warn that the patients, who undergo physical examination with use of a computer tomograph, hoping to find out a cancer tumor at an early stage, run the risk to earn a cancer as a result of examination.
According to the experts, using a computer tomography of all body, the patient receives the same doze of an irradiation that was received by the people who were in two and a half kilometers from epicenters of nuclear explosions in Hiroshima and Nagasaki.
The doze of the radiation during the full examination on a computer tomography 100 times exceeds a doze received, for example, during mammography - radiological examination of mammary glands.

Researchers have found out that the calcium contained in dairy products, can destroy a brain, informs The Sun.
Scientists believe, that this element can narrow blood vessels that leads to dementia at older persons. And vitamin D which promotes calcium assimilation and is important for formation of bones can only aggravate the situation.
Results of the research with the participation of older persons in the age from 60 till 86 years have shown that with other things being equal, people who used a lot of calcium and vitamin D had more tissue involvement in a brain.
Scientists believe that calcium precipitations block vessels and prevent blood from coming to a brain.
Doctor Martha Pain from Duke University in Northern California, who conducted the research, says: “The more researchers are worried about consequences of calcium surplus, especially when advertising induces to take it in big amounts”.

The amount of antidepressant prescriptions in the Great Britain in 2006 has reached 31 millions. Such information was published in the research of the British public organization Mind engaged in problems of mental health.
The exact number of the British regularly taking antidepressants remains unknown; however, experts consider that there are a few millions of them.
The last generation antidepressants are the so-called selective inhibitors of the return serotonin capture. Despite of the efficiency of these drugs, it is not recommend to take them for treatment of slight forms of depression because of dangerous side-effects: first of all, the increased susceptibility to a suicide and dangerous behavior of patients.
According to Mind’s data, consumption of these drugs in the Great Britain has increased by 10 % in comparison with the last year. The general number of drug prescriptions has increased by 6 %.
In opinion of the researchers, the responsibility for a developed situation lays on doctors who too willingly prescribe drug therapy, and seldom use alternative methods, such as psychotherapy and physical exercises which are also effective in treatment of slight forms of depression.

Sun-protection creams do not give a sufficient degree of skin protection and only dense fabrics, such as woolen and jeans, can rescue from cancer and other dangerous consequences of ultra-violet radiation, stated the Swiss scientists.
Scientists from Triemli hospital in Zurich have compared about 500 various researches of different skin protection means in an article on a website of the British medical magazine Lancet. They came to a conclusion, that the most inefficient of them is sun-protection cream. The cream can protect from solar burns and easy forms of skin cancer, but it does not rescue from most dangerous of them, such as melanoma.
Light linen and cotton fabrics also do not always cover sufficiently, and if they are light or damp, they can even lower a degree of protection. Basing on the results of the research scientists recommend fitting clothes from dense fabrics, for example jeans or woolen, wide-brimmed hats, - and if possible do not go out in the sun at all.
In their article scientists recognize, what not everyone will be ready to follow their recommendations.
“People shouldn’t misuse sun-protection creams trying to increase time of being in the sun “, - warn they.
Cancer Research UK recommends to stay in a shadow during the hottest time - from 11 o’clock in the morning up to 3 one o’clock in the afternoon, to wear sports shirt, a hat and solar glasses and to use at least SPF 15 cream.
