Gelatin, as an amphoteric polyelectrolyte, can combine with cationic or anionic organic compounds by ionic bond. In this work, two binary quaternary ammonium salts have been prepared from 1,2-ethanediamine and 1,4-butanediamine. The viscosity of aqueous gelatin solution containing these two organic salts is studied systematically, which verifies the occurrence of the crosslinking between the gelatin and the binary quaternary ammonium salts. This crosslinking improves the thermal stability of the dried gelatin.

Background Dengue shock syndrome (DSS) is characterized bysevere vascular leakage and hemostasis disorder. It is the cause of death in 1 to 5 percent of cases. WH 0 management guidelines for resuscitation remain empirical rather than evidence-based.Objective To find out the alternative fluids to replace plasmaleakage in DSS.Methods We performed a prospective study and randomizedcomparison of plasma and gelatin solution for resuscitation ofIndonesian children with DSS. We randomly assigned 25 subjectswith DSS to receive plasma and 25 children to receive gelatinfluid. Statistical analyse were performed using chi-square test,Fisher's exact test, t test, Mann-Whitney test.Results The increment of pulse pressure width and the decrement of hematocrit in subjects treated with gelatin were higher than that of plasma atfour-hour therapy (P=0.002 and P=0.017). Only one patient died caused by unusually manifestation of DSS. The increment of body temperature in subjects treated with plasma was higher than that of gelatin at four-hour therapy (P=O.Oll). The decrement of platelet count in subjects treated with gelatin were less than that of plasma (P=0.018). The increment of diuresis rate in subjects treated with gelatin was higher than that of plasma at twenty-hour therapy (P<O.OOOl). The decrement of respiratory rate in subjects treated with gelatin was higher than that of plasmaat twenty-eight hour therapy (P=0.018). There was no differencein studied variables : total volume rate, blood pressure, pulse rate, re-shock rate, clinical fluid overload, allergy reactions, bleeding manifestations, and length of stay (P>0.05).Conclusions Gelatin solution can be used as volume replacementin resuscitation of DSS if blood plasma is not available especiallyat four-hour therapy.

In order to explain the interaction between collagen and nano-silver, gelatin solution was blended with nano-silver particles (AgNPs) with particle size 26 mm, and then the mixture was interacted under different time, pH and temperature. The changes in the process were measured by UV-Vis, fluorescence spectroscopy, dynamic light scattering and FT-IR. The results showed that the main type of reaction between gelatin and AgNPs was electrostatic interaction and the interaction was diffusive encounters. The particle size and distribution of nano-silver would not be affected by gelatin, however, there was dynamic fluorescence quenching of gelatin after nano-silver particle induced. The longer time and lower pH were beneficial for the interaction process while the interaction balanced after 60 min and pH 3.0 resulted in the most drastic interaction. Moreover, nano-silver would not impair gelatin structure during the interaction process. In short, the results in this work might be a foundation and reference for applying nano-silver in antibacterial leather producing.
