The gel used, as modulator is a soluble mixture of purified type A gelatin from porcine skin and a polysaccharide, type III carrageenan K in nanopure water [ 17 ] . Both components are commercially available for laboratory use (Sigma Chemical Co, St Louis, Mo).
Among anionic polymers considered as topical microbicides to prevent sexual transmission of HIV-1 {Carbomer 974P/BufferGel, carrageenan, CAP, cellulose sulfate, dextran/dextrin sulfate, poly(napthalene sulfonate) and poly(styrene-4-sulfonate)}, CAP formulated in a micronized form, is the only compound which has a capacity to remove from physiological fluids infectious virus by adsorption onto the micronized particles.
They include: (1) sulfate esters of polysaccharides {carrageenan [ 1 16 17 18 19 ] , cellulose sulfate [ 12 13 14 15 ] , and dextran or dextrin sulfate [ 1 2 3 4 5 6 7 8 9 10 11 ] }; (2) aryl sulfonates {poly(naphthalene sulfonate) [ 22 23 24 ] and poly(styrene-4-sulfonate) [ 20 21 ] }; and (3) aliphatic {Carbomer 974P/BufferGel [ 25 26 27 28 29 ] } and aromatic carboxylates {CAP [ 30 31 32 33 34 35 36 37 ] }. The anti-HIV-1 properties of these polymers are expected to depend on their complexation with virus proteins which is likely to occur mainly through the formation of salt linkages or ion pairs between oppositely charged groups on the polymers and virus proteins, respectively [ 56 ] . However, the anti-HIV-1 properties of these polymers may depend not only on their charge density, but also on the characteristics of their uncharged portions, which may be involved in hydrophobic and hydrogen bonding interactions which can elicit profound conformational changes in hydrophobic regions of proteins and cause disassembly of complex proteins consisting of subunits [ 57 ] . For these reasons it is not be expected that all anionic polymers, considered as anti-HIV-1 microbicides, would have similar biological activities.
Among the three polysaccharide sulfate esters (carrageenan, cellulose sulfate and dextran sulfate), cellulose sulfate appeared to be more effective against HIV-1 BaL than the other polymers.
Aristolochia rugosa and Aristolochia trilobata are recorded in a list of plants used worldwide and in the West Indies, Venezuela, South and Central America against snakebites and scorpion stings [ 51 52 24 43 40 53 ] . Caribs in Guatemala use Aristolochia trilobata root and tuber decoctions for stomach pains and use leaf tinctures for diarrhoea [ 55 ] . Aristolochic acid inhibits inflammation induced by immune complexes, and nonimmunological agents (carrageenan or croton oil) [ 56 ] . Aristolochic acid inhibits the activity of snake venom phospholipase (PLA 2 ) by forming a 1:1 complex with the enzyme [ 56 40 38 ] . Since phospholipase enzymes play a significant part in the cascade leading to the inflammatory and pain response, their inhibition could lead to relief of problems from scorpion envenomation [ 11 ] .
