Serum Protein and Immunoglobulin Levels among Nepalese Living in Southern Nepal

Objective: This study examined the levels of serum protein fractionation, immunoglobulin (Ig) and antistreptolysin O (ASO) of people (91 males and 84 females aged 10−68 years) living in the Terai region of southern Nepal, as there had previously been no information available about them. Methods: Blood samples were collected early in the morning after overnight fasting. Serum protein fractionation was carried out by cellulose-acetate electrophoresis. IgG, IgA, IgM and ASO were measured by immuno-turbidimetry with clinical kits. Results: The mean proportion of albumin (Alb) was rather low due to increased globulin (Glb). The Alb level of males was significantly higher than that of females, while the male γ-Glb level was significantly lower than that of females. The mean values of IgG, IgM and ASO for males were lower than those values for females, although the difference was significant only for the IgM value. The mean values of IgM for female age groups of 30-39 years or less were significantly higher than those for the corresponding male age groups. Age correlated positively with IgA, and negatively with ASO in both sexes. γ-Glb and IgG correlated significantly with TP, Alb, α1-Glb and IgA in both sexes. ASO correlated with β-Glb and IgA in males, and with γ-Glb and IgG in females. Conclusions: The fact that the level of γ-Glb, a major component of serum globulin, was high suggested exposure to a highly bacterial and viral environment. These results point to the need to prevent infectious diseases as well as improve their nutritional status, especially for children and young adults.

A Butter Diet Induces Higher Levels of n-3 PUFA and of n-3/n-6 PUFA Ratio in Rat Serum and Hearts than a Safflower Oil Diet

The effects of a 47-week diet of butter of safflower oil as fat in combination with casein or soy protein as protein were observed for the serum concentrations of lipids and fatty acid compositions in rat serum and heart. Serum total cholesterol (Chol) did not differ among the four experimental diet groups. In the butter groups, significantly higher low-density lipoprotein (LDL)-Chol and lower high-density lipoprotein (HDL)-Chol were observed than in the safflower oil groups (p<0.005, respectively). Higher levels of α-tocopherol were found in the butter groups than in the safflower oil groups (p<0.05) and in the casein groups than in the soy protein groups (p<0.01). In comparison with the safflower oil groups, the butter groups showed higher n-3 polyunsaturated fatty acids (PUFA) contents and lower n-6 PUFA contents in serum and the hearts (p<0.005).The ratios of n-3/n-6 PUFA in the butter groups in serum, 0.26 and 0.18, and in the hearts, 0.37 and 0.36, (butter-casein diet and butter-soy protein diet, respectively) were higher than those of the safflower oil groups of under 0.01 in serum and 0.02 and 0.03 in the hearts (safflower oil-casein diet and safflower oil-soy protein diet, respectively) (p<0.005). In the soy protein groups, higher n-3 PUFA contents in the hearts were found than those of the casein groups (p<0.05). This study suggested that the butter diet induces higher levels of n-3 PUFA and a higher n-3/n-6 PUFA ratio than the safflower oil diet in rat serum and hearts over a long feeding period.
