9. MLI in spectroscope

2. Blood : 6 tests
3 preliminary :
• kastle mayer  pink
(20 gm Koh __20gm zinc_ 2gm phenolphthalein _100 ml water )
• benzidine _ (benzidine in glacial acetic acid ) blue
• guciacum (guciacum resin in ethanol )  green
Peroxidase enzyme  oxidation of reagent in O2 source  colour
3 confirmatory :
• spectroscope (blood absorb light and give bands )_ distilled water1:10
2 bands (carboxy or oxy ) ___1 band (reduced Hb __( 4bands metHb )
_ 2( one thick )hemachromagen )))))
DON’T FORGET ( MLI)
• Teichmann s __ )hematine )_anhydrous glacial acetic acid_ rhombic
crystal
• takayama (haemochromagen ) __ 3v( NAOH _ Pyridine _ glucose )
7v (water ) needle shape crystales

8. Semen :
Florence  choline 1.5gm K iodide __2.5gm iodine __30ml water
Rhombic shape  small then enlarged  disappear  choline per iodide
Barberios spermin alcoholic solution of picric acid  needle shape crystal
