Serum lipid levels among Saudi school children in Jeddah

To determine serum lipid levels among Saudi school children in Jeddah, Saudi Arabia. The concentrations of serum lipids [total cholesterol, triacyiglycerol, HDL-cholesterol and LDL cholesterol] were measured in school children living in the Jeddah area, Saudi Arabia. A total of 495 blood samples were collected from healthy school children [290 males and 205 females]. The mean concentrations of total cholesterol in male and female subjects were found to be 4.33 +/- 0.07 and 4.32 +/- 0.08 mmol/L, respectively, whereas the triacyiglycerol concentrations were 0.99 +/- 0.05 and 0.93 +/- 0.05 mmol/L for male and female children. The mean concentration of serum HDL cholesterol in male children [1.17 +/- 0.04 mmol/L] was found to be significantly lower [p<0.01] than female children [1.29 +/- 0.05]. The mean concentrations of serum LDL-cholesterol in male and female children were found to be 1.76 +/- 0.07 and 1.65 +/- 0.08, respectively. Our results show a good average of lipid levels among Saudi school children in Jeddah area. This could be due to their good status of serum antioxidants of vitamins and micronutrients

effect of schistosoma mansoni infection on testicular lipid in mice

This study was performed to establish the changes in the level of some serum hormones [follicle stimulating hormone, FSH, leutinizing hormone, LH, and testosterone], as well as to determine the changes in the concentrations of some testicular lipid parameters [viz., total cholesterol and total triacylglycerols] of infected mice with Schistosoma mansoni for different periods of time. Electron microscopical studies were also performed to define any histological changes in the testis upon infection with S. Mansoni. The serum levels of gonadotropins [FSH, LH] showed no significant changes in infected as compared with control mice. On the other hand, the serum level of testosterone showed a significant decrease [P <0.001] in infected as compared with control mice starting from the 14th week post infection. Testicular lipids showed a significant increase [P <0.01] in the concentration of total cholesterol and a significant decrease [P <0.005] in the concentration of total triacylglycerols in infected as compared with control mice, especially at late stages of infection [14 - 20 weeks post infection]. However, electron microscopical studies showed nonsignificant histological changes in the testicular tissues of infected mice at different stages of infection
