Journal of Organic and Pharmaceutical Chemistry| Резюме: | Aim. To study the influence of physicochemical parameters of litholytic compositions on the degree of dissolution of phosphate calculi.Results and discussion. A number of factors affecting the effectiveness of litholytic compositions on dissolution of phosphate renal calculi have been studied. It has been shown that with increasing the temperature of the solution above 38.5°C the increase of the dissolution rate of the mineral component and denaturation of the protein matrix of the calculi are competitive processes. It has been determined that the degree of litholysis while increasing the speed of the calculus washing increases linearly. The optimal values of temperature, solution feed rate and complexon concentration for dissolution of renal calculi in vivo have been determined taking into account the physiological capabilities of the kidney.Experimental part. 73 native, surgically removed calculi were used in the experiment. The stratification of the calculus was visualized by staining with Kumassi R-250. The chemical and structural homogeneity of phosphate calculi was determined by analyzing their infrared spectra. IR spectra were obtained on a Specord M-80 spectrophotometer in KBr tablets. An ION 700 instrument (Eutec Instruments) was used to control the pH of the medium.Conclusions. It has been shown that taking into account the physiological capabilities of the kidney the temperature of litholysis solutions should not exceed 37.5°C, the optimum feed rate of the solution is 5 mL/min, and the effective complexon concentration is 0.02 – 0.20 mol/L.Received: 13.03.2020Revised: 05.05.2020Accepted: 29.05.2020 |
