ABSTRACT It is well known that several plant extracts have a lactogenic effect. This response may be induced through the stimulation of prolactin release from lactotrope cells. A partial purification of the active compound indicated that it is rich in pectin and β-glucan. These materials stimulate secretion of prolactin from hypophyseal fragments. In the present study, the effect of β-Glucan on the secretion of prolactin from GH3/B6 pituitary tumor cells has been investigated. These cells are good tools for studying the direct effect of β-glucan on prolactin secretion. The different concentrations of β-glucan (50, 100 and 200 µg/ml) increased secretion of prolactin within 24 hours of incubation in GH3/B6 media. Moreover, the secretion of prolactin was significantly elicited at 100 and 200 µg/ml of β-glucan incubation after 48 hours. These results suggest that β-glucan can affect the synthesis and/or release of prolactin, a hormone that plays many important physiological roles from GH3/B6 pituitary tumor cells.

    ABSTRACT: Lyophylized beer and extracts of plants used to prepare beer have been administered orally to mature virgin rats and intravenously to ewe. After four days of treatment, beta-casein estimated by a radioimmunoassay was present in the mammary glands of the rats to which beer or barley extracts were given. Injections of lyophilised beer, barley or malt extracts triggered the release of prolactin in ewe whereas hop extracts were inactive. The active compound present in beer barley and malt, was insolubilized in 50% ethanol and it is in the aqueous phase in chloroform extraction. The active preparation contained essentially polysaccharides. This suggests that the lactogenic principle belongs to this class of macromolecule.

    ABSTRACT: Pectins from apple, citrus and sugar beet injected intravenously to ewes markedly stimulated blood prolactin, growth hormone (GH) and cortisol. Pectic acid and polygalacturonic acid exhibited the same property. A preparation of oligogalacturonic acid with a polymerisation degree of 12 to 13 was also active, whereas oligomers with a smaller degree of polymerisation (congruent to 10) were devoid of activity. Pectic acid administered orally to mature virgin rats induced the accumulation of beta-casein in mammary gland. Pectins and some of their derivatives therefore had a lactogenic property and their effect probably resulted from a capacity to trigger lactogenic hormone secretion.

    ABSTRACT: Aquous extracts of brewery draff injected intravenously into ewes and cows induced prolactin and growth hormone (GH) secretion. The same draff added to the feed of cows appeared to be unable to significantly stimulate the blood level of prolactin and GH. In these experimental conditions, milk production was not enhanced by draff. Pure beta-glucan extracted from barley also stimulated hormone secretion when administered by the intravenous route. Barley, bier and draff therefore contain a beta-glucan-like factor which stimulates lactogenic hormone secretion. The amount present in draff is probably unable to cause an increase in hormones when administered orally. Hence, the well-established stimulatory effect of draff on milk production results from their nutritive value rather than from their ability of modulating the endocrine system.
