Background: Typhoid is a vital health hazard globally but its incidence is greater in developing compared to developed countries owing to low sanitation, poor hygiene practices, unsafe food and drinking water. Objective: This study was designed to determine the changes in renal parameters associated with male and female Typhoid patients. Materials and Methods: A hundred and twenty male and hundred and twenty female Typhoid patients were divided into four groups made up of sixty Typhoid positive male, sixty Typhoid negative male, sixty Typhoid positive female and sixty Typhoid negative females. The renal parameters were evaluated using Spectrophotometer. The results were analyzed using statistical package for social science version 20 statistical software. Results: The result of renal changes associated with male and female Typhoid fever patient showed insignificant increase (p < 0.05) in Total serum Protein and significant increase (p < 0.05) in Creatinine level of both male and female patient compared to their control. It showed insignificant increase (p < 0.05) in potassium ion and sodium ion of the Typhoid positive male patient, significant decrease in sodium ion and insignificant decrease in potassium ion of the Typhoid positive female compare to their controls. Similarly, the result of the Typhoid positive male patients showed significant increase (p < 0.05) in Chloride ion and insignificant decrease (p < 0.05) in Chloride ion of Typhoid positive female compare to their control. Furthermore, it showed insignificant decrease (p < 0.05) in Urea level of the Typhoid positive males and insignificant increase (p < 0.05) in Urea level of the Typhoid positive females. Conclusions: Renal parameters as a tool for examining cases of early typhoid infections may aid in detecting early complications related to typhoid fever so as to aid in patients care and avert death that may come from such complication.

Equilibrium Effect

1. Calculations from the Fick diffusion law are shown to predict that membrane equilibria should be established during the course of ultrafiltration. 2. It is shown that the chloride ion is more concentrated and the sodium ion less concentrated in the ultrafiltrate than in the plasma from which the ultrafiltrate was derived. 3. It has been found that by increasing the base bound by protein through a reduction in the bicarbonate content the difference between the plasma concentration and the ultrafiltrate concentration for the several ions studied increases. 4. Calculations from the Donnan equation as to the magnitude of the change in base bound by protein at differing hydrogen ion concentrations are in substantial agreement with the observed values, thus rendering it probable that the membrane equilibrium effect is responsible for the change in distribution ratios observed. 5. It is pointed out that the observed difference in the distribution ratio of cations from that of the chloride anion is probably to be explained by the influence of protein in lowering the activity coefficient of cations when on the alkaline side of the isoelectric point. 6. It is pointed out that account must be taken of these observations in any consideration of the rôle of ultrafiltration in the production of any secretion or body fluid.

Проведено исследование фазовых равновесий в тройной системе Sn–As–P в области высокой концентрации летучих компонентов. Методами рентгенофазового и дифференциального термического анализа изучены сплавы политермического разреза SnAs–P. Показано, что растворимость фосфора в моноарсениде олова в направлении этого разреза менее 0.05 мол.д. фосфора. Построена Т-х диаграмма политермического сечения SnAs–Р. Наличие на Т-х диаграмме горизонтали при температуре 827±2 К соответствует реализации в системе Sn–As–P нонвариантного перитектического равновесия L + (d) ↔ b + g , где (d), b и g – трехкомпонентные твердые растворы на основе As1-xPx, SnAs и SnP3 соответственно     REFERENCES Zhang W., Mao J., Li S., Chen Z., Guo Z.
