The factors and mechanisms by infection of Oriental Tsutsugamushi caused disease are not well understood. The onset of tsutsugamushi disease is characterized by chilliness, fever, malaise, headache and generalized aching. Infection of tsutsugamushi is the cause of impairment of function of a major organ often complicate the picture and immediately change the prognosis for the worse. Tsutsugamushi disease is reported that this disease is characterized by the histopathogenesis of liver, kidney, heart, and lung, but the variation of biochemical components in serum of tsutsugamushi disease patient are not clear. We analyzed total protein (TP), albumin (AL), aspartic aminotranferase (AST), alanine aminotransferase (ALT), alkaline phosphotase (ALP), urea nitrogen (UN), creatinine (CRE), glucose (GLD), cholesterol (CHOL) and total bilirubin (TB) in sera of patients with tsutsugamushi disease. In comparison with reference, total protein and albumin were abnormally decreased in 19.6% and 39.2% of patients, respectively. AST, ALT, ALP, creatinine, UN, glucose, cholesterol and total bilirubin were abnormally increased in 94.1 %, 72.5%, 25.5%, 15.7%, 9.8%, 62.7%, 25.5% and 6.0% of patients, respectively. The patients showed abnormal relative rate of protein electrophoretic fractions to total protein in serum compared to them of reference were 43.1% (albumin), 12.9% ($\alpha_1$-globulin), 58.8% ($\alpha_2$-globulin), 60.8% ($\beta$-globulin) and 70.6% ($\gamma$-globulin), respectively. These data suggest that infection of Oriental Tsutsugamushi causes impairment of function of a major organ and abnormal serum protein electrophoresis fractions to tsutsugamushi patients.

The mechanisms by which leptospires caused disease are not well understood. A number of putative virulence factors have been suggested, but with few exceptions their role in pathogenesis remains unclear. In these days, many cases of leptospirosis are diagnosed by serological immunoassay. Leptospirosis is characterized by the histopathology of liver, kidney, heart, and lung, but the electrophoresis fractions of serum protein are not compared. We analyzed total protein, albumin, aspartic aminotranferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), creatinine and urea nitrogen (UN) in sera of patients diagnosed leptospirosis. Total protein and albumin were decreased in 18.5％ and 31.2％ of patients, respectively. AST, ALT, ALP, UN and creatinine were increased in 90.4％, 66.9％, 28.0％, 15.9％ and 10.8％ of patients, respectively. We performed cellulose acetate membrane electrophoresis (EP) on sera of patients increased both of AST and ALT, and of patients increased both of creatinine and UN. In patients increased both of AST and ALT, and in patients increased both of AST and ALT, the relative percentage of albumin to total protein in patient serum was dcreased in 89.1 ％ of patients. α₁-globulin, α₂-globulin, β-globulin and γ-globulin were increased in 85.1 ％, 75.2％, 33.6％ and 98.0％ of patients, respectively. In patients increased both of creatinine and UN, the relative percentage of albumin to total protein in patient serum was dcreased in 93.8％ of patients. α₁-globulin, α₂-globulin, β-globulin and γ-globulin were increased in 87.5％, 100％, 31.2％ and 93.8％ of patients, respectively. These data indicate that infection of Leptospira causes severe liver damage to most of leptospirosis patients, but doesn't cause renal damage to most of them. The relative rate of serum protein electrophoresis fractions to total protein are not identical with them of typical hepatitis patient.
