<"Burn" Topic Continued from Last Year!> I hope you all had a happy winter break. For me, work starts on January 3rd on Tuesday. I hope my persistence on this question about thermal burns is not annoying anyone.

The red is definitely due to the immune response. It is part of the inflammatory reaction. Is the 'whiteness' due to the immune response? I doubt it but I could be wrong. As I said, my burn injury [from touching a hot plate] looked white. I am not sure why the injured skin looked white. My thinking is that the heat damaged the dermal pigments in that area. Once again, I could be wrong. > In answer to your question about what would happen to your burnt > tissues in a week, it would turn black and begin to smell very bad as > bacterial decomposition sets in. I am aware of this. However, in my rules, infection or microbial decomposition canNOT occur. So if there was no bacterial [or any microbial] decay, how would the burn look like? Under my -- too good to be true in today's technology -- rules, inflammatory reactions also canNOT occur. So how would the burn look like? > See "gangrene" and "frostbite" for > what happens to dead tissue as a function of time. Already know about this. However in my rules, this would not occur. The injured tissue would either remain a "fresh" wound for life OR it would spring back to a normal and un-injured state as soon as direct contact with the open flame is stopped. > PD > > Of course, burning the skin would effect the rest of the > > body.

If you're going to come up with such a totally fabricated scenario in which you are making up your own rules, you can probably justify any colour of the rainbow.

ahahahaha.... Why are you obsessing with this? Turn it into fun!: Do an experiment and then obsess enjoying it, getting your answers first hand: Fry an egg!... Ever heard of egg-white? ...observe, conclude, eat! Fry a fresh, transparent fish- or shrimp piece. ...observe, conclude, eat. First the transparent proteins denaturate/coagulate and turn white. Then keep frying and its glyco/sugar type components caramelize and turn brown, and upon further frying they "char" into black stuff, wherein an early stage of it (under certain conditions) makes the fabeled "Dulce-de-Leche" -- for the palate -- ahhhh... mmmhh... mmmh... ahhh... generated by the Maillard-Strecker reaction as in the 97,100 google hits for "Maillard reaction" with the executive recipe in http://www.milk.com/recipes/dessert/dulce-de-leche.html which creates this delectable dessert that contains... (so the enviro-shits will warn you -- to spoil your fun and joy)... these mutagenic Furanoses, Pyrazines and Aldehydes and Acrylamide... ahahaha.... but be macho make yourself a batch of "Dulce-de-Leche" and test whether you have succumbed to the sick, paranoid and fucked up propaganda of the enviro turds and whether these green shits have been able to even ruin your desserts..........ahahahahaha.....AHAHAHA..... Enjoy chemistry...... but fuck enviros! ahahahaha.......ahahahanson > "Radium" <glucegen1@excite.com> wrote in message news:1136143280.750000.71290@o13g2000cwo.googlegroups.com... > <"Burn" Topic Continued from Last Year!> > > Is the 'whiteness' due to the immune response?
