Mast cells/eosinophilic granule cells of teleostean fish: a review focusing on staining properties and functional responses

“…Reviewers of the early literature on tissue mast cells seemed to have no doubt that mast cells were present in bony fish as well as in amphibians, reptiles, birds and mammals (Michels, 1938;Arvy, 1955b;Riley, 1959;Selye, 1965;Reite, 1972). During the following 20 years several investigators questioned the presence of true mast cells in fish (reviews by Ellis, 1977Ellis, , 1982Fänge, 1992).…”

The effect of sex and of sex and thyroid hormones on the induction of cancers in the salivary glands of rats.

“…The most obvious differences between male and female salivary glands are concerned with the volume and secretory activity of the tubules of the submandibular gland which in males greatly exceed those of females and which diminish after castration or hormonal treatments (Arvy et al, 1950;Grad and Leblond, 1949; Jacoby and Leeson, 1959;Lacassagne, 1940a, b;Shafer and Muhler, 1956). The male submandibular gland of mice also produces more of the nerve growth factor (Levi-Montalcini, 1965) and of the epidermal growth factor (Cohen, 1965) than the female, though the secretion can be stimulated in the female by testosterone.…”

“…In addition each of the four groups has been treated with testosterone, with stilboestrol or with testosterone plus stilboestrol. Because of the influence of the thyroid on the submaxillary gland (Arvy, Debray and Gabe, 1950; Arvy and Gabe, 1950a, b;Grad and Leblond, 1949; Hammett, 1923; Shafer and Muhler, 1956), we have also investigated the influence of L-thyroxine and of methylthiouracil on tumour induction in intact and castrate male and female rats. The sexual dimorphism of the salivary glands in rats and mice (Grad and Leblond, 1949;Jacoby and Leeson, 1959;Junqueira, Fajer, Rabinovitch and Frankenthal, 1949 ; Lacassagne, 1940a, b; Shafer and Muhler, 1953) has been established particularly with regard to the submandibular gland.…”

Hormonal relationships of mastocytogenesis in lymphatic organs

“…Correlations of the pineal body and thyroid have been examined by several authors (Arvy andGabe [1950J, Scepovic [1963], IIoranyi [1966], Ishibashi and Hahn [1966]) including ourselves (Csaba et al [1967]) and these relations appear to be satisfactorily verified. The thyroid has been found to affect the production of mast cells (Arvy and Gabe [1950], Conte et al [1954], Arvy [1955], Constantinides and Rltherdale [1957], Smith and Lewis [1958], Kelly and Bloom [1959], Poulsen [1959], J ozsa et al [1964]) either directly or through a TSlI-thyroid regulation system. Correlations between the thyroid and thymus have already been described (Conte el al.…”
