Abstract: A syringe dispenser may include a plunger having an outer threading, a barrel adapted to contain liquid or semisolid fluid or any other material to be dispensed and to receive the plunger, the plunger being movably attached to the barrel, and a nut having an inner threading. The nut may at least partly enclose the plunger and the barrel, such that the inner threading of the nut engages with the outer threading of the plunger. A stand, an application plate, and a method of dispensing a controlled and measurable amount of liquid or semisolid fluid from a syringe dispenser are also disclosed.

Abstract: A composition is described, which comprises a cationic, hydrophilic, amine containing cationic derivatives of native chitosan; bound to an anionic scavenger substance, which is either (a) selected from the group consisting of anionic ethylene amine compounds, tetraazacycloalkane-N,N,N,N-tetraacetic acids; and polymer derivatives of porphyrines, or, (b) in the case of use in an UV radiation absorbing formulation, an antiviral, antifungal or anti-inflammatory formulation, an endogenous compound wherein cationic derivatives of native chitosan are not covalently bound to DTPA or EDTA; the amount of EDTA exceeds 0.5 wight percent; and taurine and taurine derivatives are not present.
