Plasma-HDL-cholesterol levels were determined in 104 patients (92 males and 12 females) with a mean age of 43 years (range 20-70 years). All were admitted to a clinic for alcoholics and had a mean drinking history of 13 years with a mean consumption of 48.2 l of pure ethanol per year. There was no correlation between HDL-cholesterol level and the total ethanol consumption in the year before admission or in the month before admission. However, weak negative correlations between HDL-cholesterol and smoking habits (r= -0.26, P less than 0.001) and body weight (r= -0.34, P less than 0.001) were found. In 40 patients the mean HDL-cholesterol level decreased from 1.94 +/- 0.75 mmol/l (SD) at admission to 1.29 +/- 0.36 mmol/l after 16 days of abstinence. Altogether, 33 (31.6%) of 104 patients had a HDL-cholesterol level above our reference value of 2 mmol/l while alanine aminotransferase (ALAT), aspartate aminotransferase (ASAT) and gamma-glutamyltranspeptidase (GGT) were increased in 49, 52.9 and 70.3%, of the cases respectively. Although screening programmes have shown an association between plasma-HDL-cholesterol and the number of drinks consumed per day, no such association could be found in a sample of alcoholics. Decrease of HDL-cholesterol during abstinence, however, seems to be a marker in alcoholics.

Twelve serum analytes [triglycerides, cholesterol, total and conjugated bilirubin, high-density-lipoprotein cholesterol (HDL-C), alkaline phosphatase (AP), gammaglutamyl transferase (GGT), aspartate aminotransferase (AST), alanine aminotransferase (ALT), beta-glucuronidase (beta-glu), alanine aminopeptidase (AAP), and 5'-nucleotidase (5'nuc)] were measured to investigate their correlation with exposure to polychlorinated biphenyls (PCBs) and 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT). The relationship between serum lipids, lipophilic toxicants, and the analytes was also evaluated. The beta-glu, 5'nuc, triglycerides, cholesterol, and total bilirubin correlated positively and significantly with log concentrations of serum total PCBs and 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene (DDE), a metabolite of DDT. The more highly chlorinated PCBs (Aroclor 1260) had significant, positive correlations with several serum analytes, but the less chlorinated PCBs (Aroclor 1242) correlated significantly and negatively only with HDL-cholesterol. Triglyceride- and cholesterol-rich lipoproteins were added to serum to determine the effects of lipids on these assays. Several were spuriously elevated. AP and beta-glu were not affected by lipoprotein addition with the methods used in this study. AAP was increased significantly only at triglyceride concentrations exceeding 400 mg/dl. Lipoproteins may be elevated because of deranged lipid metabolism in response to PCBs, or PCBs may be elevated because elevated lipoproteins are present, as in familial triglyceridemia, a relatively common dyslipoproteinemia. Because this relationship is not well understood with respect to cause and effect, we propose the further use in epidemiological investigations of assay methods that are little affected by blood lipids yet are correlated with PCB concentrations. Congener-specific quantification of PCBs would help elucidate the effects of PCBs on assays used to monitor health effects.

Blood analyses were performed concerning glucose, uric acid, potassium, total protein, s-GOT, S-GPT, total cholesterol, HDL-, LDL-cholesterol, triglycerides, iron, ferritine, iron binding capacity (IBC), hemoglobin, thiamine, riboflavin, ascorbic acid. Significant changes with regard to improving blood levels at the end of period L, compared with the initial position, could be registrated for the following parameters: uric acid, s-GPT, HDL-, VLDL-cholesterol, triglycerides, IBC, thiamine, ascorbic acid. In both periods, the food volumes actually eaten served basically for the comparison of clinical-chemical parameters. Only a few subjects with inconvenient blood levels had an inadequate intake of the nutrient that was to be correlated with a blood parameter. On the other hand, every blood parameter showed subjects with levels above the average of the group, but averaging, at the same time, far beyond the group's nutrient supply.

Data on blood lipids and liver function from 90 young women from a computer file on oral contraceptive users were analyzed. Subjects selected were 30 Bisecurin users, 30 Ovidon users, and 30 Anteovin users, aged 17-25, who had smoked 20 cigarettes/day or less. Triglycerides increased significantly (p0.001) at 1, 3 and 6 months for all groups. Total cholesterol also rose significantly for all groups at all time points. HDL rose significantly in Bisecurin and Anteovin users, and fell in the Ovidon group, at 6 months, and variable at other times. The liver enzymes GGT and GPT increased progressively, while AP fell. Laboratory values remained within normal limits. Varicose veins in 1 patient was the only complication. Side effects were listed with each pill formulation; Anteovin caused fewer side effects than the other pills.

The purpose of the study was to investigate the physiological assessment of a lacto-ovo-vegetarian diet, in comparison to a usual mixed diet and to analyse the effect of a lacto-ovo-vegetarian diet on nutritional status and blood parameters. Following an initial study, 34 resp. 33 subjects, three of them male took part in two investigation periods each lasting three weeks. During the first period (N) the subjects ingested the normal mixed diet, while in the second period (L) they were fed a lacto-ovo-vegetarian diet. The female subjects were aged 52.6 +/- 14.3 years, the male subjects 47.7 +/- 12.7 years. In both periods food supply ensued from the central kitchen of a nunnery. While preparing the meals, the food intake and the amount of nutrients was assessed with precise weighing methods. Also, the individual food consumption of the total subjects was estimated using food records. The nutritional physiological evaluation was based on the daily consumption of energy and nutrients to assess the nutrient supply, by means of the recommended dietary allowances of the German Nutrition Society. At the beginning of period N and both at the beginning and the end of period L, blood tests of the following parameters were performed: serum glucose, uric acid, and potassium, total protein, total cholesterol, HDL-, LDL-, VLDL-cholesterol, triglycerides, serum ferritin, serum iron, iron binding capacity, hemoglobin, s-GOT, s-GPT, thiamine, riboflavine, ascorbic acid. Measurements of body weight and height, body composition, skinfold thickness, circumferences, body surface, relative weight, blood pressure and sitting pulse rate completed the investigations. Furthermore, meal frequency and the daily individual energy requirement of the subjects were assessed by means of a diary of energy expenditure. On average, the daily energy consumption of women was 2020 +/- 611.3 kcal in period N, and 1970 +/- 592.4 kcal in period L. Consequently, there was a covering of energy requirements of 103% in period N and 99% in period L. Sources of energy consisted of 14% protein, 36.4% fat and 49.6% carbohydrates in period L, 13.6% protein, 39.6% fat, 44.7% carbohydrates and 2.1% alcohol in period N.

Hypolipidemic effects of gamma-oryzanol (OZ) and cycloartenol ferulic acid ester (CAF) on the hyperlipidemia induced by ingestion of a high cholesterol diet (HCD) in male Sprague-Dawley rats were investigated. The test drugs were given orally and intravenously, daily for 12 days with the HCD feeding. The oral administration with OZ and CAF at 100 mg/kg daily for 6 or 12 days did not apparently prevent the hyperlipidemia induced by HCD-feeding. The intravenous administrations with OZ and CAF at 10 mg/kg for 6 days significantly inhibited the increases in serum total cholesterol (TC), phospholipid (PL) and free cholesterol by HCD. OZ and CAF did not inhibit the decreases of TC in high density lipoprotein (HDL-TC) and HDL-PL by HCD. The increases of atherogenic index [( TC-HDL-TC]/[HDL-TC] and [PL-HDL-PL]/[HDL-PL]) with the HCD feeding were reduced by the intravenous administrations of OZ and CAF. Triglyceride, nonesterified fatty acid, lactate dehydrogenase and transaminase (GOT and GPT) markedly decreased below the control level by the intravenous administrations of OZ and CAF for 12 days. These results suggest that the intravenous administrations of OZ and CAF may have accelerated the excretion of lipids in the blood.

The effect of nicardipine on experimental hyperlipemia induced by a 1% cholesterol diet in spontaneously hypertensive rats (SHR) was investigated by the change of hemodynamics and the determination of lipid contents of the serum, liver, heart and aorta. Nicardipine increased liver weight and liver weight per body weight ratio, and it decreased heart and kidney weight significantly. Nicardipine inhibited the increase in blood pressure with cholesterol and normal diets. Nicardipine decreased heart rate in SHR fed the normal diet, and it inhibited the increase in heart rate in SHR fed the cholesterol diet. Serum lipid levels significantly increased with the cholesterol diet. Nicardipine significantly increased cholesterol in high density lipoprotein (HDL-C) and phospholipid in HDL (HDL-PL) with cholesterol and normal diets, and it decreased triglyceride and improved the atherogenic index "(total cholesterol-HDL-C)/HDL-C" with the normal diet. Serum GOT and GPT significantly increased with the cholesterol diet. Nicardipine significantly enhanced an increase in GOT and GPT levels with the cholesterol diet. Nicardipine increased phospholipid content in the liver, triglyceride in the heart, and it decreased total cholesterol in the aorta. A morphologic study showed a fatty liver in SHR fed the cholesterol diet, but nicardipine had no effect on the morphological changes in the liver, heart and aorta. These results suggest that nicardipine may prevent atherosclerotic degeneration by the inhibition of hypertension, increase in serum HDL and decrease in total cholesterol in the aorta.

The plasma lipid and apoprotein concentrations were monitored in a group of 12 patients with chronic alcohol abuse entering an abstinence program for 3 weeks. 6 of them had a normal liver function as expressed by the levels of liver enzymes gamma GT, GOT, GPT, while 6 had elevated plasma liver enzyme concentrations. None had evidence of either cirrhosis or alcohol hepatitis. Patients with abnormal liver enzymes had elevated HDL-cholesterol, apo AI and apo AII concentrations in plasma, with normal total cholesterol and apo 8 concentrations. In the group of patients with normal liver enzyme concentrations, the apoproteins and lipids did not significantly differ from the control group. In the course of the abstinence treatment a parallel decrease of apoproteins, HDL-cholesterol and liver enzyme concentrations was observed. The values normalized after 10-15 days. These data indicate that the effect of alcohol on the plasma apoprotein and lipids occurs mostly in the HDL fraction, that it correlates with the state of hepatic function and that it can be reversed by an abstinence treatment.

We investigated the effect of Probucol in preventing fatty liver in monosodium-L-glutamate (MSG) treated obese mice and control mice fed a high fat diet. MSG mice became significantly obese 9 weeks after birth with higher levels of serum blood glucose, total cholesterol, HDL-cholesterol, GPT, and cholinesterase, and had greater triglyceride contents in their livers relative to control mice. Morphologically, MSG obese mice also had a marked fatty liver. Administration of Probucol mixed with the high fat diet for 2 weeks significantly decreased the serum levels of total cholesterol and HDL-cholesterol, and liver triglyceride contents in both MSG and control mice. Morphologically, the livers were less fatty after Probucol treatment. These results suggest that Probucol prevents the development of fatty liver, and in addition reduces hypercholesterolemia.

Information on the stability of serum analytes during storage of serum or whole blood samples is often incomplete and sometimes contradictory. Using a widely available analyser (Hitachi 737/Boehringer), we therefore determined the effects of storage time and temperature on the measured concentrations of the following serum analytes: sodium, potassium, calcium, chloride, inorganic phosphate, magnesium, creatinine, urea, uric acid, bilirubin, cholesterol, HDL- and LDL-cholesterol, triacylglycerols, creatine kinase, aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltransferase, alkaline phosphatase, alpha-amylase, lactate dehydrogenase and cholinesterase. When separated serum was stored at + 9 degrees C for seven days, the mean changes in inorganic phosphate and lactate dehydrogenase exceeded significantly (p < 0.05 or 0.001, respectively) the maximum allowable inaccuracy according to the Guidelines of the German Federal Medical Council; all other quantities were sufficiently stable. In serum at room temperature, inorganic phosphate, uric acid, HDL-cholesterol and triacylglycerols increased continuously, whereas bilirubin, LDL-cholesterol, creatine kinase and aspartate aminotransferase decreased more than the guidelines permit during the storage period (p < 0.05 for aspartate aminotransferase, p < 0.001 for the other analytes mentioned). In whole blood stored for 7 days at + 9 degrees C, only the following serum analytes satisfied the stability requirements of the guidelines: calcium, urea, cholesterol, HDL-cholesterol, LDL-cholesterol, triacylglycerols, creatine kinase, gamma-glutamyltransferase and cholinesterase. When stored at room temperature, only sodium, uric acid, bilirubin, cholesterol, triacylglycerols, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, alpha-amylase and cholinesterase were still stable after 3 days. The data collected show that all quantities examined are sufficiently stable for four days in separated serum stored at + 9 degrees C.
