The total ion chromatogram (TIC) extracted from GCFID of oily sludge from T1 to T6 composed of n-alkanes ranged from nC10 to nC34 with traces of isoprenoids such as pristane and phytane.
For each station, the individual n-alkane concentrations, the isoprenoids ( pristane and phytane) concentrations, the total resolved aliphatic (rAH), the unresolved complex mixtures (UCM), and the total aliphatic (TAH) fractions were calculated.
Mice were separated into two groups: pristane induced lupus (PIL) group which received a single intraperitoneal injection of 0.5 mL of pristane (2, 6, 10, 14-tetramethylpentadecane) and healthy control (HC) group which received phosphate-buffered saline injection in a different cage.
Arthritis developed within two weeks after a single pristane injection which is assessed through total leukocyte count.
Arthritis developed in Group B, C and D within two weeks after a single intra-dermal injection of pristane. Body-weight measured on electronic balance in grams and clinical score of inflammation scored on macroscopic scoring system were monitored on every alternate day while total leukocyte count and differential leukocyte count were taken at day 0, 16 and 30.
