It is believed that alcohol impairs the protective barrier of the peripheral nervous system order kamagra super 160mg on line, on the one hand order kamagra super 160mg amex, and can be a risk factor for development of chronic hyperglycemia purchase kamagra super with paypal, breaking the utilization of B vitamins. Timely correction of vitamin metabolism disorders, along with other therapeutic measures, can prevent the development of polyneuropathy or to facilitate its flow. Aim: to study aspects of pharmacotherapy of alcoholic polyneuropathy drug Neyromultivit®. All the patients underwent a thorough clinical and neurological examination with the study of anamnestic data. Polyneuropathy results confirmed data electroneuromyographic, was observed in 62 (71%) patients with alcohol dependence who were randomized into 2 groups: the main group (n = 30) received Neyromultivit® 1 tablet 3 times a day for 21 days, and a control group (n = 32) that received the standard vitamin therapy (B1, B6, B12) drugs administered parenterally. In the course of the study in both groups noted a decrease in the severity of pain (clinically and scales). No significant differences in efficacy and safety between the two groups of patients receiving Neyromultivit®, and a group of patients treated with vitamins parenterally received. The study showed the effectiveness of treatment of alcoholic polyneuropathy by Neyromultivit® when dosing regimen of 1 tablet 3 times daily for 21 days as an equivalent replacement of B vitamins for intramuscular injection. According to epidemiological studies worldwide nonallergic rhinitis affects about 450 million people. Nonallergic rhinitis is not-IgE-mediated disease with chronic nasal symptoms such as nasal congestion, rhinorrhea, sneezing. The study of modern pharmacotherapy nonallergic rhinitis according to current standards of care for patients with nonallergic rhinitis. The analysis of contemporary foreign literature on aspects of pharmacotherapy nonallergic rhinitis, standards of care for patients with rhinitis. For pharmacotherapy nonallergic rhinitis group of drugs used are nasal anticholinergics, nasal steroids, nasal sympathomimetics and systemic antihistamines. Among nasal corticosteroids are widely used beclomethasone dipropionate, budesonide, fluticasone propionate, mometasone, fluticasone furoate. Among the nasal anticholinergic agents according to foreign sources recommend nasal ipratropium bromide. Among the designated nasal sympathomimetic is oxymetazoline, xilometazoline, nafazoline, tramazoline, tetryzoline. Systemic antihistamines such as loratadine, dezloratadine, cetirizine, levocetirizine are used. For vasomotor rhinitis, drugs of choice are nasal anticholinergic and sympathomimetic drugs. For pharmacotherapy nonallergic rhinitis with eosinophilic syndrome, nasal corticosteroids and nasal sympathomimetic are recommend. The nasal corticosteroids, antihistamines, nasal anticholinergic and sympathomimetic drugs prescribed hormonal rhinitis. For the treatment of rhinitis occupational shows nasal corticosteroids and nasal antihistamines. Treatment of drug-induced rhinitis nasal corticosteroids is carried out, and the gustatory rhinitis used nasal anticholinergic drugs. Having analyzed the current foreign and domestic sources revealed that drug therapy used nonallergic rhinitis nasal anticholinergics, nasal steroids, nasal sympathomimetics, antihistamines. Polio is one of the most dangerous childhood diseases, which can lead to death or severe disability. Today, only two countries in the world Afghanistan and Pakistan are polio-endemic. To study the basic aspects of epidemiology, etiology, pathogenesis, clinical manifestations, treatment and vaccination of poliomyelitis. To completely eliminate the incidence of polio has been developed polio eradication strategic plan and the implementation of the final stage in the 2013-2018. Penetrating into the human body, the virus replicates in the oropharynx and the intestine, penetrate the regional lymph nodes. Approximately 1% of the virus from infected blood-brain barrier and overcomes affects nerve cells, predominantly large motor neurons of the anterior horns of the spinal cord and motor nuclei of the brain stem nerve that leads to the development of acute flaccid paralysis of muscles. In rare cases, viral destruction of bulbar cells leads to paralysis of the respiratory muscles and death. Vaccination of children for polio prevention is carried out according to the immunization schedule at ages 2 months, 4 months, 6 months, 18 months and 6 years and 14 years. Nowadays drugs received from natural plant materials occupy a leading position in present medicine and pharmacy. The main advantage of these phytodrugs compared to synthesized analogues is in the possibility of rational use among all groups of patients. And also it is worth noting that they function when there are strict contraindications to synthetic ones. That is why the search for effective and safe herbal medicines with a broad spectrum of pharmacological activity is so promising. Screening research and proving new-found effective dose of Salix bark extract on experimental anti-inflammatory activity using the model of acute edema. Anti-inflammatory effect of Salix extracts was demonstrated on normal model of acute inflammatory edema induced by subcutaneous phlogogenic agent – carragenan. The model describes the exudative phase of acute inflammation in the pathogenesis, where biogenic amines, prostaglandins and kinin–kallikrein system play the leading role. In order to eliminate the effects of fluctuations in hormonal levels the experiment was conducted in laboratory through applying to white male same age and weight (180-200 g) rats of the Wistar line. The substances were divided into doses according to animals‘ body weight and were injected intragastric in an hour after subcutaneous injection of 0. Anti-inflammatory activity is determined by the degree of reduction of edema in tested animals compared to control groups and expressed as a percentage. After the screening test the effective dose of Salix bark extract was found in dose 10 mg, in terms of the animal weight the dose was reduced to 2 mg on a rat. It caused inhibition of experimental edema in 55% compared to the compared preparation diclofenac sodium - 93%. The experimental results and argumentative analysis show that Salix bark extract is perspective in founding effective dose for further study of its specific pharmacological activity and safety. And it absolutely could be implemented into the practical medicine in future as effective and convenient way to overcome most dangerous diseases and even warn them at all. Acute kidney injury by the various chemicals with exogenous and endogenous origin is fairly widespread self-pathology, or is found in the complex pathological processes of multiple organ dysfunction syndrome, failure. Prognosis of acute kidney injury depends on its type: in pre-renal and postrenal - relatively favorable (full recovery of glomerular filtration rate reached more than 90% of cases, and the mortality rate is less than 7. Given that the majority of toxic substances cause the renal form of acute kidney injury, pathogenetic mechanism of which is to defeat the epithelium of the renal tubules from toxic metabolites and inhibition of cell respiration due to ischemia of the renal parenchyma, we investigated effects of reamberin on protein dynamics in serum and urine in experimental acute kidney injury. Acute kidney injury modeled using a single injection of a 50% aqueous solution of glycerol, intramuscularly at a dose of 10 ml/kg. Important links of the pathogenesis of this experimental model is the development of rhabdomyolysis, myoglobinuria with toxic both glomerular and tubular kidney apparatus. Reamberin experimental group was administered 14 days intragastrically at a dose of 5 ml.

Getting your hands on Cuttings and Seeds: The easiest way to start growing cactus is from cuttings. When you find it, dug it up and transplant it and then use it’s cuttings and seeds to grow more. Growing Tips for our Spiny Friends: Cacti are part of a larger group of plants called succulents. Through natural selection most Cacti species lost their leaves, which allowed too much evaporation in the desert. To protect themselves from the Sun and predators many species developed spines and hair, waxy skin, along with bitter alkaloids. Most Cacti do fairly well as house plants, but however they are quite slow growing. Be sure and save the sunniest spots in your house for your Cactus plants as they need lots of light. If you are going to grow some of your Cacti to flower, or for seeds, then don’t move them while in bloom. Don’t be in a hurry to scorch them under a hot July Sun, give them a month or more to get gradually get used to it. If after you put it outside your cactus starts to acquire a lighter green or tan tint, it is probably sunburned, move it to some shade. Watering: As a rule water your Cacti seldom, and be very careful not to over water. Cacti and other succulents prefer hot and dry conditions and a soil that affords good drainage and aeration. Let the soil dry out completely between waterings during the growing season, and water even less during the winter. When watering your Cactus don’t forget to use lukewarm water, cold water can shock the roots. A good way to test if your cactus needs water is to poke a small, clean redwood stake in the soil. Different Soil Types: A good soil mix is essential if you expect good growth and health for your Cactus. There are several good brands of commercially available Cactus soils that come prepackaged. For those of you who want to do it yourself, here are a few recommended soil formulas. Also add one Tablespoon each of ground bone meal and ground limestone per gallon of mix. If you are making your own soil it would be a good idea to sterilize the mixture by baking in an oven at 400 degrees F for 60 minutes. Fertilizing your Cactus: All mature actively growing cacti need to be fed occasionally. A commercial formula such as miracle grow or rapid grow can be used, but should be diluted to half strength. Regular Bone Meal, available at most Garden Centers, makes an excellent organic fertilizer. Don’t forget the macro-nutrients like Iron (Fe), Calcium (Ca), Sulfur (S), and Magnesium (Mg). Also important are the micro-nutrients Copper (Cu), Zinc (Zn), and Manganese (Mn). A location where the plant gets at least 4 hours a day of bright, direct sunlight is ideal. The best possible situation would be a South facing sliding glass door, and a reflective screen placed behind the Cactus to redirect and concentrate the light. Many Cacti have beautiful and fragrant flowers, but they can be quite hard to get to bloom. The optimal conditions to induce flowering are, a cooler temperature (especially at night), reduced day length (12 hours or less), and variations in nutrients (lower nitrogen levels). Try putting your Cactus in a dark, unheated garage (not below freezing) for a few weeks. Forcing can also be done inside, but you need a place next to lots of glass that stays cooler than the rest of the house. Planting/Transplanting: Cacti prefer to be in unglazed clay pots with a layer of course gravel and charcoal in the bottom. Most Cacti have far ranging lateral roots so a shallow, wide clay pot is preferred. Be sure not to put your cactus in too large a pot because that can lead to later problems. Avoid transplanting too many times as this can also shock the plant, pick one size and stick with it a while. When handling small Cacti, use a pair of tongs, and for larger ones, use a rolled up newspaper. Cactus spines can be very sharp and can penetrate gloves, as you may well become aware of. During dormancy water is not taken in as rapidly by the plants roots, nor does it evaporate as quickly, and the result might be root rot. If possible bring your cactus inside the house and place it by a sunny window so it can continue to grow (slowly) through the winter. Cacti are well suited to being packaged for extended periods without light or water, they will almost always arrive at your house in good condition. Since Cacti are tough and hardy, they don’t have to be shipped by an overnight service, like most tropicals. About a couple weeks before the first hard frost (see Farmer’s Almanac for dates) I make sure that the soil dries up completely (shielding the plants from rain if required). Then I just move the containers inside my garage to protect the cacti from freezing. The temperature in the attached, but unheated garage drops to about 38 degrees during the coldest part of Winter. The cacti remain sheltered in the garage, in total darkness, all Winter until I bring them out in the Spring after all danger of frost is past. I usually keep them under a shaded patio for a week or so, and slowly move them to partial direct sun, then full sun over the course of two weeks (they are subject to sunburn if exposed to direct sun immediately after emergence from the dark. I use Miracle Grow plant food (as directed for container plants, even though they are exposed to the rain outdoors. By July there is usually some good new growth which is very explosive in August and continues (slower) into late September. By late October the cycle continues and they are again placed in the dark shelter of a garage.
