Higher Doses

Nutritional supplements containing soybean phytoestrogens, the isoflavones genistein (G) and daidzein (D), are increasingly used as alternative therapy for osteoporosis, cancer, and cardiovascular and other diseases with a frequency that increases with advancing age. In this study we examined the effects of subcutaneous administration of either G or D on serum lipid levels in orchidectomized (Orx) and intact (IA) middle-aged male rats, which are experimental models of andropause. Sixteen-month-old Wistar rats were treated with 10 mg/kg and 30mg/kg of either G or D. The control groups received testosterone, estradiol, or vehicle for 3 weeks, after which the total serum cholesterol (TC), low-density lipoprotein (LDL-C), high-density lipoprotein (HDL-C), and total triglycerides (TT) were measured. Compared with the matching vehicle-treated controls, the higher doses of G and D and testosterone treatment significantly ( P < 0.05) lowered the TC and lipoprotein cholesterol levels. The greatest effect was observed regarding LDL-C in both Orx and IA males after G and D treatments, in which LDL-C decreased by more than 30%. The lower isoflavone doses induced a significant cholesterol-lowering effect ( P < 0.05) only in the Orx group. Like the estradiol treatment, the higher doses of G and D increased the TT levels in both rat models by more than 50% ( P < 0.05). The lower doses of isoflavones increased TT only in the Orx group. In male middle-aged rats, injections of higher doses of G and D decreased the serum cholesterol levels, as did testosterone injection, and brought about an increase in serum triglycerides similar to that observed after estradiol treatment.

Cholesterol Levels

The increased level of LDL-c in the serum has a high risk and the increased serum HDL-c level has a low risk for the development of atherosclerosis. The effect of Nigella Sativa on levels of cholesterol fractions were determined in this study on rats. Methods: 24 albino rats of 08 weeks age having equal number of males and females were kept at optimum atmospheric condition. The blood samples were taken at the start and different control and experimental diets were given for 24 weeks. The experimental diets were added with Nigella Sativa as 30 mg/kg body weight. The blood samples were taken at the end of study. The blood samples drawn at the start and end of the study were estimated for serum cholesterol. The results of control and experimental groups were compared. Results: Total serum cholesterol in the control group showed increase from 8.3±3.30 to 13.96±9.3 at 24 weeks. The serum HDL cholesterol showed increase from 44.4±6.12 to 80.45±5.95 level at 24 weeks. The serum LDL cholesterol showed increase from 8.3±3.30 to 13.96±9.3 at 24 weeks. The total serum cholesterol in experimental group was increased from 76.9±6.5 to 117.5± 6.65 at 24 weeks. The serum HDL cholesterol levels was increased from 41.7±4.9 to 83.42±5.92 at 24 weeks as compared with control group. The LDL cholesterol levels were decreased from 12.7±6.9 to 8.5±7.8 at 24 weeks. Conclusions: This study shows significant decrease in serum low density lipoprotein cholesterol level, and increase in serum high density lipoprotein cholesterol levels.

Egg Yolks

Magnesium/phosphotungstic acid was confirmed as specific for precipitation of chylomicrons, low-density and very low density lipoprotein particles in serum from healthy volunteers who were either fasting or who had eaten egg yolks or a salmon sandwich containing Flora margarine 2 hours previously. In eight subjects who ate salmon sandwiches that contained butter or Flora margarine, neither the total cholesterol nor the high-density lipoprotein (HDL) cholesterol differed significantly from the fasting level over 7 hours. In eight subjects, egg yolks also did not alter significantly either the total serum cholesterol or the HDL cholesterol at ½, 1, 1½, 2, 5, and 7 hours after eating. Patients may be screened for HDL cholesterol and total cholesterol estimation when not fasting. However, individual subjects showed variation in their total cholesterol and, particularly, HDL cholesterol over a three-month period. Replicate analysis of HDL cholesterol may be required for its complete assessment.
