Artery proteoglycan-lipoprotein binding characteristics were determined using intact, high molecular weight chondroitin sulfate proteoglycans (CS-PG) isolated from grossly appearing normal aortas of atherosclerosis susceptible WC-2 pigeons and plasma lipoproteins from normolipemic, randomly bred White Carneau pigeons. Optimum formation of particulate proteoglycan-lipoprotein complexes occurred in 5 mM Tris, 6 mM KCl, 4 mM CaCl2, 1 mM MgSO4, pH 7.2. The binding of CS-PG was specific for low density lipoprotein (LDL) and not high density lipoprotein (HDL). The relative importance of the intact monomeric structure of the PG was suggested in studies where glycosaminoglycan chains isolated from the PG monomer possessed less than 1% of the binding reactivity of the intact PG. The core protein prepared from the CS-PG monomer formed no measurable particulate complex.

Numerous clinical reports suggest the beneficial effects of chelation therapy for the treatment of atherosclerosis. However, the results of these studies are inconclusive and controversial. The purpose of this present study was to examine the prophylactic and therapeutic effects of chelation liquid (CHL) in experimental atherosclerosis. Twenty New Zealand white rabbits were fed a 1% cholesterol-supplemented diet for 45 days. In the prophylactic phase of the study subcutaneous 300 mg EDTA + 500 mg magnesium sulphate (MgSO4) injections (five rabbits) and isotonic saline (five rabbits) were given to test and control groups, respectively, along with cholesterol rich diet. The CHL treatment ameliorated the rise of serum cholesterol and serum triglyceride concentrations, lowered serum calcium concentrations and reduced the aortic atheroma. In the therapeutic phase of the experiment the cholesterol diet was stopped and the remaining 10 animals were returned to normal diet. Five of these rabbits were given CHL injections and other five animals were given isotonic saline injections for 121 days. Although the level of cholesterol and triglyceride were not significantly different in the two groups, the serum calcium concentration and the percentage of the area of flate aortic specimen occupied by atheroma were significantly lower in the CHL treated rabbits as compared to controls. It is concluded that CHL injections have a definite prophylactic effect on atherogenesis in the cholesterol-fed rabbit, and may have some therapeutic value in the regression phase. Further confirmatory studies are suggested.

The hypertensive disorders of pregnancy remain a leading cause of maternal and perinatal morbidity and mortality in Europe and North America. Pre-eclampsia, which is proteinuric gestational hypertension, accounts for the majority of the excess risks and is defined by the maternal syndrome. The maternal syndrome of pre-eclampsia is characterised by a systemic inflammatory response and its sequelae. Systematic multisystem evaluation of pre-eclampsia, evidence-based antihypertensive therapy, and the use of MgSO4 to prevent and treat the seizures of eclampsia can reduce maternal risks. For mild-to-moderate pregnancy hypertension, maternal risks are small, and there may be adverse perinatal consequences of blood pressure normalisation. Early-onset and severe pre-eclampsia predict an excess risk of later cardiovascular morbidity and mortality. Both Chlamydophila pneumoniae and cytomegalovirus have bee associated with pre-eclampsia and atherosclerosis, and may provide a mechanistic link between pre-eclampsia and the recognised cardiovascular risk. Women with a history of either early-onset and/or severe pre-eclampsia should be considered to be at increased risk for later cardiovascular disease, and it may be prudent for them to have regular lipid profiles and tests for urinary microalbumin excretion.

Magnesium (Mg) deficiency is known to promote vascular and cardiac dysfunctions such as atherosclerosis. This study investigated the effect of oral MgSO4 therapy to improve lipid profile and serum oxidized LDL level and its receptor (LOX1) in moderate coronary atherosclerotic patients. In this randomized double-blind placebo-controlled clinical trial study, 64 patients with moderate coronary artery disease were selected according to angiography findings. Participants were divided into 2 groups including Mg-treated (n = 32) and placebo (n = 32) The patients received either placebo or MgSO4 supplement capsule, containing 300 mg MgSO4 for 6 months on a daily basis. Lipid profile, HbA1c, 2h postprandial (2hpp) blood glucose, fasting blood sugar, serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), oxidized low-density lipoprotein, and lectin-like ox-LDL receptor 1 (LOX1) concentrations were measured at baseline and every 3 months. HbA1c, serum LOX1, and oxidized low-density lipoprotein concentrations were significantly lower in the Mg-treated group than the placebo group 3 months after MgSO4 administration. 2hpp, serum low-density lipoprotein cholesterol, SGPT, SGOT levels, and HbA1c levels significantly improved in the Mg-treated group compared with the placebo-received group. Overall, the results of this study showed that magnesium treatment improved some of the major risk factors of atherosclerosis. According to the results of liver function tests (SGOT and SGPT), magnesium therapy seems to be safe in patients with moderate atherosclerotic plaque. Therefore, it is suggested that magnesium to be used along with other atherosclerosis control drugs.
