's prevention and health care of first class prevention of gastric carcinoma
Though gastric carcinoma cause of disease final to expound strip takes some time, may get several main precautionary measures out of already according to existing research, in order to spare no effort to lighten the danger to the mankind of gastric carcinoma.
2.1 Block internal NOC to formate
Outside the body and animal's experiment has already been found, many kinds of nutrition in meal and it is not that the nutrition can inhibit NOC from formating strongly, reduce it and cause mutation, carcinogenic function, and have clear dosage reaction relations. Such as vitamin C, Vitamin E, some microelements and many acyl compound,etc.. NOC in human body blocked and studied and opened in 1981 by Ohshima and Bartsch. While experimenters take to suck 325mgNO3 - beet beetroot juice and 250mg proline, take 1g vitamin C or 500mg Vitamin E, the intersection of NPRO and person who discharge reduce notably in the 24-hour urine, vitamin C block rate reach 80%, Vitamin E 50%. A lot of scholars thereafter have proved the above-mentioned result. Leaf,et al. quantitative research shows, under controlling the meal strictly, after taking in 445mgNO3 - and 500mg proline every day, take 8.8mg vitamin C at the same time and inhibit NPRO from formating the result promptly. The discharging to number value and NPRO of vitamin C and NO3 - fine long hair More's ratio Quantity is presented and shouldered notably relevantly (r2 =0.96),The return equation is: NPRO (mmol day) =23.9-5.96log[VC(mmol) /NO3-(mmol) ]. But up to 1000mg vitamin C can't make, take in above-mentioned forebody discharge amount of NPRO reduce to the intersection of ins and outs and competence this behind the thing, this may relate to the fact that NOC of many routes formate the body. Vitamin C is blocked in the water looks effectually, the Vitamin E is opposite, it is relatively strong to inhibit the result in the lipoprotein looks, so both sharing will make better inhibition result. The field study of high-risk group of gastric carcinoma indicates, vitamin C of 100mg * 3 can be totally blocked in the body enhanced and inferiorly and nitrified function. Prove vitamin C, Vitamin E, zinc and selenium to the intersection of cancer of the esophagus and high person who take place a too high one inferior to nitrify function, have prominent blocking the result in the the intersection of people and colony already also.
2.2 reduces NO2 - content while drinking the water
NO2 - quantity that the mankind is taken in by the other environment directly is very small. The human body one NO2- main source to be reducing internal NO3 at meal,it is can reach 5% not to estimate. In NO3- crowd taller in intaking amount, this has already offered enough NO2- for formating NOC in the body. NO3 - content in gastric carcinoma, high crowd of taking place area of the cancer of the esophagus drink the water is obviously higher than the low taking place area, therefore NO3 - quantity drunk the water and taken in is quite high. It is inferior while nitrifying the course in the human body, it may be very different to come from NO3 - and NO3 - this meaning from fresh vegetables while drinking the water. Stomach inferior to nitrify competence depend on inferior to nitrify pharmaceutical (NA, a broad one include NO2 -, NO3 - the intersection of content and NO2-, NO,etc.) Nitrify inhibitor (NIA) with Asia Mole ratio. In not drinking the water except NA such as NO3 NO2-,last NIAs such as vitamin C, Vitamin E,etc. hardly, so getting more favorable extremely to it is inferior that if you can't nitrify, react. And the fresh vegetables have obvious inhibition NOC synthesis. It in addition reduce it drink the water it take in on NO3- method getting easier relatively,so not should consider first-selected precautionary measures. NO3 under drinking water that WHO recommend - a large amount of 50mg/L the most, this consider NO3 - function until human tumour have illness coming on yet. NO3 - maximum recommending amount will be dropped from 50mg/L to 25mg/L in Britain would drink the water in 1985.
