The present study was performed to investigate the relevance of cholesterol levels of plasma lipoproteins [HDL (high-density lipoprotein), LDL (low-density lipoprotein), IDL (immediate-density lipoprotein), VLDL (very-LDL) and chylomicrons] determined by a novel HPLC method, with adiponectin, which is decreased in Type II diabetes and assumed to be involved in dysregulated metabolism and atherogenesis. Type II diabetic patients who were not treated with insulin, statins and fibrates were enrolled. Study subjects included Type II diabetic patients with normolipidaemia (DM-NL; n=15), type 4 hyperlipidaemia (DM-T4HL; n=13), Type IIa hyperlipidaemia (DM-T2aHL; n=15) and Type IIb hyperlipidaemia (DM-T2bHL; n=13). Fasting blood samples were collected. The serum adiponectin level was lower in DM-T2bHL than in any of the other groups. Cholesterol levels of each lipoprotein fraction, serum triacylglycerol (triglyceride), remnant-like particle-cholesterol, fasting plasma glucose, HbA1c (glycated haemoglobin), age, gender difference and BMI (body mass index) were incorporated into a stepwise regression analysis as independent variables. VLDL-cholesterol correlated inversely with adiponectin independently of age, BMI, gender difference and glycaemic control. Although the mechanisms remain to be explored, serum adiponectin was reduced particularly in Type II diabetics with type IIb hyperlipidaemia and correlated inversely with VLDL-cholesterol. Measuring VLDL-cholesterol may be helpful for understanding the pathological features of diabetic dyslipidaemia.

Markers of metabolic abnormalities are commonly found in rodents fed a fructose-rich diet. The purpose of this study was to determine whether the administration of a short-term standard diet to rats is able to improve the lipid profile altered by a fructose-rich diet. The male pups, immediately after birth, were divided in three groups according to the diet for 90 days. Standard diet: a standard diet for the whole experimental period; fructose (60% fructose-rich diet): fructose-rich diet during the entire experimental period; fructose/standard (FS): fructose-rich diet from the neonatal period up to 60 days of age and standard diet from 60 to 90 days of age. A fructose-rich diet from the neonatal period to 60 days reduced weight gain (P<0.05), as well as the weight of adipose tissues in all the regions analyzed (epididymal, mesenteric, retroperitoneal and posterior subcutaneous), and it altered the lipid profile (elevation of triglycerides, total cholesterol, low density lipoprotein (LDL) cholesterol and very low density lipoprotein (VLDL) cholesterol;P<0.05). When a standard diet was administered after the fructose-rich diet, it was able to partially reverse changes to the lipid profile, as total cholesterol levels were significantly different in all the groups (P<0.05), and triglyceride and VLDL cholesterol levels were similar between the control and FS group. In summary, a fructose-rich diet altered the lipid profile, and a standard diet can partially reverse the changed parameters in short term.

1. Plasma lipids and lipoproteins have been studied in control subjects and patients with various types of steatorrhoea. 2. Low plasma cholesterol levels were found in malabsorbers and were associated with decreased amounts of low-density lipoprotein (LDL) in males and high-density lipoprotein (HDL) in females. 3. Serum triglyceride levels were normal in males, but exceeded control values in some of the females, due to an increase in very-low-density lipoprotein. 4. LDL composition was abnormal in both male and female malabsorbers, with a decreased proportion of cholesterol ester and an increased proportion of triglyceride. There was also an increased proportion of triglyceride in HDL. 5. These findings show that malabsorption markedly influences not only the concentration but also the composition of plasma lipoproteins.

This study consists of two parts; the Part one is to evaluate the level of Blood glucose and lipid profile  among diabetic patients(121 patients) which are compared with non-diabetic subjects (60 persons)  and  part two is to correlate lipid profile with cardiovascular abnormalities among type II diabetic patients. The diabetic patients were collected from Jabir Aboeleiz Center for Diabetes (51.9±11.22 years). Sixty healthy non-diabetic subjects were chosen as controls (52.44±10.76years). Blood glucose, total cholesterol (TC), triglycerides (TG) and high density lipoprotein (HDL) were measured by enzymatic colorimetric methods in both groups, and low density lipoprotein cholesterol (LDL) was calculated for each sample. Among diabetic patients, there is high glucose level, serum total cholesterol, triglycerides and LDL cholesterol (p<0.5), while low level of HDL cholesterol was observed when compared to non-diabetic subjects. No statistically variation was found in the level of glucose and lipid profile between male and female diabetic patients. In our study, we have found that serum lipid - cholesterol, triglycerides and low-density lipoprotein - levels were significantly (p < 0.05) correlated to cardiovascular abnormalities, while HDL had shown a statistically non-significant correlation (p>0.05). The study concluded that higher level of cholesterol, triglyceride and LDL-cholesterol in diabetic patients compared to non-diabetic subjects with lower level of serum HDL-cholesterol in diabetic patient compared to non- diabetic subjects.Keywords: Diabetic, Insulin, Mellitus and lipid.

Significant Difference

The extent of lipoprotein glycation was assessed in 82 patients diagnosed as diabetes mellitus type II. Glycated lipoprotein levels in serum were determined by agarose gel film electrophoresis in 48 non-diabetic control subjects, 56 diabetics with complications and 26 diabetics with no complications. All glycated lipoproteins were higher in the patients when the diabetics were compared to the control group, but glycated very low-density lipoprotein (VLDL) was the only glycated lipoprotein fraction that was observed to be higher in the diabetic patients with complications compared to the patients without complications ( P < 0·01). Triglycerides and VLDL-cholesterol were also increased in the diabetics, but there was no significant difference in these variables when the patients without complications were compared to the control subjects. There was no difference in total cholesterol and low-density lipoprotein (LDL)-cholesterol levels of the diabetic patients compared to the controls.

SummaryHuman plasma lipoprotein fractions were prepared by flotation in the ultracentrifuge. Addition of these fractions to platelet-rich, platelet-poor and platelet-free plasma affected the partial thromboplastin and Stypven clotting times to various degrees. Addition of high density lipoprotein (HDL) to platelet-poor and platelet-free plasma shortened both the partial thromboplastin and the Stypven time, whereas addition of low density lipoprotein and very low density lipoprotein (LDL + VLDL) fractions only shortened the Stypven time. The additions had little or no effect in platelet-rich plasma.Experiments involving the addition of anti-HDL antibodies to plasmas with different platelet contents and measuring of clotting times produced results that were in good agreement with those noted when lipoprotein was added. The relation between structure and the clot-promoting activity of various phospholipid components is discussed.
