%0 Journal Article %T THE INFLUENCE OF Ca-ASCORBATE ON CHANGING THE ILEUM SENSITIVITY %A Voja Pavlovi£¿ %J Acta Medica Medianae %D 2004 %I The Faculty of Medicine in Nis %X In the case of previously mentioned Hartley guinea pigs, male gender, weight from 250 to 300 g, which lived under normal lab¡¯s conditions. The effect of different Ca-ascorbate concentrations was studied. Various Ca-ascorbate concentrations were used starting from 10-6 M to 10-1 M, while the sensitivity of thermal part of ileum was determined by Shultz-Dale¡¯s reaction.The samples of ileum treated by 10-5 M histamin and the received contraction has served as a maximal response (100%). Ileum sample was rinsed by Thyrode¡¯s solution, the media was exchanged by different contractions of Ca-ascorbate, and with the help of Shulzt-Dale¡¯s reaction, determined by the intensity of ileum contraction.The received results show that, with the growth of Ca-ascorbate concentration, from 10-6 M till 10-3 M. There is a mild growth of vitamin C concentration. This is in order to get 50% of response, and it¡¯s the greatest when 10-1 M Ca-ascorbate concentration is applied.These results show that the application of Ca-ascorbate lessons the sensitivity of thermal ileum part. %K Ca-ascorbic %K vitamin C %K asscorbic acid %K histamin %K ileum %K sensibilisation %K Schultz-Dale-ova reaction %U http://publisher.medfak.ni.ac.rs/2004-html/4-broj/UTICAJ%20CA-ASKORBATA%20NA%20PROMENU....pdf
