Biosynthesis of Prostaglandins from Arachidonic Acid in Guinea Pig Lung
The prostaglandins constitute a class of physiologically active compounds with a widespread occurrence in animal tissues (see References 2 and 3). Previous studies have led to the determination of their structures (4-S), and more recent investigations have shown that they can be formed enzymatically from the essential fatty acids (7,8). It was thus shown that in homogenates of vesicular glands ...
متن کاملRelaxant effect of pioglitazone on the guinea-pig isolated trachea through the modulation of endogenous prostaglandins
Thiazolidinediones are commonly used anti-diabetic drugs. Owing to the anti-inflammatory action of TZDs as a result of there action on the PPAR gamma receptor and a proposed action on the prostaglandins, these drugs can be tried in the acute exacerbations of COPD that are also commonly found among diabetic patients. An experimental study of one week was carried out at animal house of Army Medic...
متن کاملKaryotype of Hairless Guinea pig
Chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. Chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and G banding techniques. The chromosomes diploid number was 2n= 64 and polymorphism of three type chro...
متن کاملActions of arachidonic acid on contractions and associated electrical activity in guinea-pig isolated ventricular myocytes.
The actions of arachidonic acid (AA) were investigated in guinea-pig isolated ventricular myocytes. Exposure of myocytes to 10 microM AA reduced the amplitude of contractions and calcium transients accompanying action potentials at a frequency of 1 Hz. AA (10 microM) also reduced the amplitude of calcium currents recorded under voltage-clamp conditions. The suppression of contraction by AA was ...
