Prostaglandins: methodology.

Prostaglandins

Knowledge of the structure and synthesis of antibodies (immunoglobulins) has developed to a remarkable degree in the last decade. Distinct classes of immunoglobulin (yG, yM, -yA, yD, yE, and their subgroups) have been identified and shown to consist of fixed numbers of light and heavy polypeptide chains organized in pairs. Each polypeptide has a segment of variable amino acid sequence; the spec...

Prostaglandins and glaucoma.

Human aqueous humour was found to contain a substance which contracted the rat stomach strip. The mean activity was significantly higher in specimens from open angle glaucoma cases than in specimens from patients with cataract. The pharmacological and chromatographic properties of the active material were studied in aqueous humour obtained from cadavers; activity seemed to be due to prostagland...

Gastrointestinal cytoprotection by prostaglandins.

Prostaglandins (PGs) are widely distributed throughout the gastrointestinal tract and affect a variety of gastrointestinal functions. The observation that PGs of the E and A series are potent inhibitors of gastric acid secretion and that PGs, especially the E compounds, are released into the gastric lumen during vagal or gastrin stimulation suggests a possible physiological role for these agent...
