Protamine Sulphate Hypersensitivity

Cardiovascular depressant effect of protamine sulphate: experimental study and clinical implications.

The mechanisms underlying protamine-induced hypotension and bradycardia were the subject of this investigation. Six groups of dogs with intact circulation were tested in controlled circumstances with various drugs. The following parameters were observed: femoral arterial pressure, central venous pressure, left ventricular pressure and its rate of rise, left ventricular contractile element veloc...

Comparison of intravesical application of chondroitin sulphate and colchicine in rat protamine/lipopolysaccharide induced cystitis model.

PURPOSE To investigate beneficial effect of the readily available colchicine through its intravesical application on protamine/lipopolysaccharide induced interstitial cystitis model in rat and to compare its efficacy to the chondroitin sulphate available for clinical use. MATERIALS AND METHODS Twenty-four Wistar female rats were assigned to control (C), interstitial cystitis (IC), chondroitin...

Assessment of a DNA vaccine encoding an anchored-glycosylphosphatidylinositol tegumental antigen complexed to protamine sulphate on immunoprotection against murine schistosomiasis.

Protamine sulphate/DNA complexes have been shown to protect DNA from DNase digestion in a lipid system for gene transfer. A DNA-based vaccine complexed to protamine sulphate was used to induce an immune response against Schistosoma mansoni anchored-glycosylphosphatidylinositol tegumental antigen in BALB/c mice. The protection elicited ranged from 33 to 44%. The spectrum of the elicited immune r...

Effects of protamine sulphate on spontaneous and calcium-induced contractile activity in the rat uterus are potassium channels-mediated.

Protamine sulphate (PS) effect on spontaneous and calcium-induced rhythmic contractions of isolated virgin rat uteri was studied. PS caused dose-dependent relaxation of both types of contractions (two-way ANOVA, significant dose effects). Pretreatment with NG-nitro-L-arginine methyl ester (L-NAME; 10(-5) mol/l), methylene blue (MB; 0.9 x 10(-6) mol/l) or propranolol (1.7 x 10(-5) mol/l) enhance...
