Tumor therapy statistics and profiles of six (tumor cryotherapy) _ Ganoderma green tea

Category: "cancer" tumor cryotherapy cryotherapy is also called hypothermia, is one of the tumor physiotherapy. Can quickly produce ultra machine, cool lesion, pathological tissue degeneration, necrosis or shedding so as to achieve the goal of treatment for cancer. Cryotherapy as an emerging medical technologies in the treatment of benign and malignant tumors has been rapid development. freezing can save organizations under certain conditions and at the same time can damage tissues, freezing treatment is the use of the latter. Freezing causes the main principles of the biological cell death are: (1) the formation of ice crystals and ice crystals in frozen cells when mechanical damage. After freeze melts, in particular the slow melting nature makes the cells gathered into small ice crystals in ice crystals, cell destruction. (2) gradually concentrated frozen extracellular fluid, inside and outside the cells induced by osmotic pressure differences, cells by intracellular fluid extravasation of dehydration and wrinkling. (3) cell dehydration, wrinkling and electrolyte concentrations increase, the activities of frozen interference, causing cell toxicity and injury. (4) when frozen cell PH value lowering, acidic, exacerbated by protein denaturation. (5) membrane lipoprotein degeneration caused by freezing, so that the rupture of membranes. (6) to freeze living tissue can cause small blood vessels constrict, melts, small blood vessels expand, penetration increases, slow blood flow sedimentation. At the same time. Frozen capillaries quickly when tethered, microcirculation stops, causing ischemia. to sum up, freeze causing the death of cells is the combined result of a number of factors. Liquid nitrogen is by far the broadest application of cryotherapy in the refrigerant, its low boiling point (-196 ' c), the use of safety, sources widely. Addition to solid state carbon dioxide, nitrous oxide, chlorofluorocarbons, hyperbaric oxygen, liquid oxygen, nitrous oxide, also can be used as refrigerants for medical use. Clinic for the treatment of tumors of the frozen liquid nitrogen freezer, high pressure oxygen "cool tool", thermoelectric device, and so on. Frozen for clinical at this time there are basically 5 types: (1) exposure to freezing: frozen heads at the surface gently pressurized frozen tumor. (2) into the frozen: Insert needle frozen head tumour, to achieve the deeper parts of cancer treatment. (3) funnel into: such as liquid nitrogen cavity through a funnel into cancer. (4) the direct spray: spray the liquid nitrogen directly in the disease area, suitable for large, rugged surface area of diffusion of superficial tumors. (5) the cotton swabs or cotton balls dipped dips hemangiomas and papillomas by; white spots, warts, etc, choose the corresponding size of disinfection of cotton swabs, immersion foot of liquid nitrogen, namely vertical touch focus, scope and depth control due to freezing, scarring after healing light. freezing time depends on method of freezing and the size of the tumor, typically 30 seconds to 30 minutes, usually freeze freezing effect of 15 minutes to reach the maximum 80% a cent. now freezing treatment in the clinic is mainly used for skin, head and neck, such as the five sense organs, rectum, cervix, bladder and prostate tumors of superficial or easy to directly contact. In recent years for the liver, lungs, kidneys, pancreas and other organs of tumor cryotherapy is also actively exploring. Tumor cryotherapy of the most notable feature is the extreme low temperature in specific areas within quick reach, resulting in a perimeter of clear and predictable range of frozen necrosis. Operation of cryotherapy more secure, easy and pain-free, contraindications less, no or few bleeding; frozen tissue reactions after the lighter, fix fast, and scar healing well, sore face without skin graft, few remnants of dysfunction. Even if close to the tumor blood vessels and nerves are frozen, thawed after rupture of blood vessels often can be complex-pass without, under certain conditions, mostly non-permanent paralysis. Freezing is also likely to have immunity, as well as through freeze prevents cancer cell proliferation in the operation, freezing treatment of superficial tumors can not only destroy the tumor and able to maintain maximum organizational shape and the organ. Operative parts cannot be reached, drugs or radiation, surgery and treatment of malignant tumors of the failed, frozen preferred therapy can be done, for recurrent cancer, as a method of treatment �C, refrigeration can improve the symptoms and relieve the patient's pain. cryotherapy is a local treatment, has its limitations. On the treatment of cancer is only partial, rather than a regional (, including the lymphatic system) in tumor eradication. Freeze damage to certain malignant tumor is still have questions. Cryotherapy equipment also need improvement. Cryotherapy techniques would need to be further improved, but as cryotherapy-portal includes a number of unique properties of surgical techniques, the treatment of cancer has a broad development prospects.
