Correlation ofβ-lipoprotein levels and serum cholesterol concentration

Zusammenfassung Mit Hilfe der immunologischen Methode wurden der-Lipoproteinspiegel wie auch der Serum-, Cholesterol- und Triglyceridspiegel von 161 Erwachsenen bestimmt. Der Gehalt an Cholesterol und Triglyceriden stand in direktem Verhältnis zum-Lipoproteinwert, wobei jedoch Unsicherheit in der Voraussage der Hypercholesterolaemie auf Grund der Hypertriglyceraemie besteht.     

Lack of effect of exercise on serum cholesterol levels in two types of experimental obesity

Résumé Divers auteurs ont supposé récemment que la pratique journalière d'exercices physiques peut abaisser le taux du cholestérol du sang. Cette hypothèse a été testée chez des souris normales et chez des souris représentant deux classes d'obésité: des souris porteuses du syndrome héréditaire d'obésité-hyperglycémie (qui est accompagnée d'une hypercholestérémie génétique), représentant l'obesité «de métabolisme», et des souris rendues obèses par les lésions hypothalamiques causées par l'administration d'aurothioglucose, représentant l'obésité «de régulation». Trente jours d'exercice (une heure de course sur tapis roulant par jour) n'eurent aucun effet sur le taux du cholestérol du serum ni chez les souris normales, ni chez les deux groupes de souris obèses, et ceci en dépit du fait que la durée et l'intensité de l'exercice quotidien étaient suffisantes pour réduire de façon significative le poids des souris obèses.

Serum cholesterol levels in germ-free chickens

Résumé On démontre qu'il n'y a pas de différence entre le cholestérol du sérum de poulets élevés dans des conditions aseptiques et ceux élevés dans des conditions normales et soumis à un régime sans cholestérol. Les poulets sans bactéries croissent mieux que les poulets normaux.      

A qualitative difference between certain H-2 and Non-H-2 antigens responsible for a similar graft-rejection rate

Zusammenfassung Gezeigt wird, dass «schwache» Histokompatibilitätsantigene weniger sensibilisieren als «starke», auch wenn beide eine quantitativ ähnliche Transplantationsbarriere darstellen. Auf qualitative Unterschiede zwischen diesen Antigenen nach Vorbehandlung des Rezipienten mit lebenden Milzzellen von Mäusen wird hingewiesen.     

Influence of glutathione on serum cholesterol in rabbits

Zusammenfassung In Kaninchen erfolgt auf intramuskuläre Injektionen von 0.1 g reduziertem Glutathion nach 24 h ein hoch signifikanter Anstieg des Serumcholesterins. Kleinere Dosen, oder orale Verabreichung von 0.1 g, haben keine derartige Wirkung.Oxydiertes Glutathion,dl-Cystein und Glykokoll zeigen bei Kaninchen keinen eindeutigen und unmittelbaren Einfluss auf Serumcholesterin.

Serum cholesterol levels in a nigerian population sample

Summary Serum cholesterol was determined in 104 healthy Nigerians (57 males and 47 females). The average cholesterol concentration was 187±72.8 mg/100 ml (mean±SD) with a range of 60–480 mg/100 ml. Cholesterol levels were higher in males than in females and increased with age. Distribution of cholesterol level was generally skew to the left.Acknowledgment. I am grateful to Mr S. O. Oguike an Mr O. Uzoechi for technical assistance. I also thank Dr. E. O. Anosike for his help in arranging for the subjects of study.     

Effect of dibenzyline on serum cholesterol in rabbits

Zusammenfassung Im Gegensatz zu den Beobachtungen, die zeigten, dass adrenergische Substanzen Serumlipoide einschliesslich Serumcholesterin erhöhen, wird in kurzfristigen Versuchen an Kaninchen eine etwas unregelmässige Senkung des Serumcholesterins nach Injektion von Noradrenalin und keine signifikante Beeinflussung des Serumcholesterins nach Injektion von Serotonin gefunden. Dibenzylin erhöhte in kurzfristigen Versuchen das Serumcholesterin ausgesprochen signifikant.

Serum cholesterol levels in a Nigerian population sample

Serum cholesterol was determined in 104 healthy Nigerians (57 males and 47 females). The average cholesterol concentration was 187 +/- 72.8 mg/100 ml (mean +/- SD) with a range of 60-480 mg/100 ml. Cholesterol levels were higher in males than in females and increased with age. Distribution of cholesterol level was generally skew to the left.     

Familial association in serum IgE levels

Summary The serum IgE levels measured by RIST correlated closely with those obtained by the single radioimmunodiffusion method. Values for husband and wife were closely related as were those between father and daughter but in contrast to previous observations no significant relationship existed between IgE levels for mother and son.Acknowledgments.

Effect of preoperative stress on serum cholesterol level in humans

Summary Effect of preoperative stress on serum cholesterol level in 65 patients of different age groups in a surgical ward, has been studied. In all age groups, statistically significant rise of cholesterol in serum preoperatively was noticed as compared with serum cholesterol level at the time of discharge from hospital. The preoperative rise of cholesterol varied from 39 to 56.9% in this series. These findings support previous reports of the effect of mental tension on serum cholesterol level.Authors acknowledge with pleasure the useful discussions with Dr A. K. Ganguly, Prof. of Physiology, Government Medical College, Surat, Dr T. H. Rindani, Medical Director, Jaslok Hospital, Bombay. Statistical analysis by Shri P. Gopinath and technical assistance of Shri N. T. Pabani.

Emblica officinalis reduces serum,aortic and hepatic cholesterol in rabbits

Summary Emblica officinalis reduced serum cholesterol (p<0.001), aortic cholesterol (p<0.001) and hepatic cholesterol (p<0.001) significantly in rabbits.Emblica officinalis did not influence euglobulin clot lysis time, platelet adhesiveness or serum triglyceride levels.     

Emblica officinalis reduces serum, aortic and hepatic cholesterol in rabbits

Emblica officinalis reduced serum cholesterol (p less than 0.001), aortic cholesterol (p less than 0.001) and hepatic cholesterol (p less than 0.001) significantly in rabbits. Emblica officinalis did not influence euglobulin clot lysis time, platelet adhesiveness or serum triglyceride levels.     

The effect of pressure changes on esterification of cholesterol and hydrolysis of cholesterol esters in rat aorta and serum

Zusammenfassung Experimente in vitro zeigen, dass unter Überdruck von 200 mm Hg die Hydrolyse von Cholesteropalmitat in den Aorten und im Blutserum von Ratten gehemmt wird: Die Esterifikation von Cholesterin, in Aorten ebenfalls erniedrigt, zeigt im Serum einen deutlichen Anstieg.
