Ultrastructural aspects of human cystic duct epithelium as a result of cholelithiasis and cholesterolosis

“…Because several authors (Daignault et al, 1988;Hould et al, 1988;Singletary et al, 1986;Yamamoto et al, 1990) have demonstrated the high level of receptors for sex hormones throughout the biliary system, including the gallbladder and the cystic duct, it is possible to refer to our hypothesis (Gilloteaux et al, 1994) whereby we proposed that the gallbladder surface epithelium morphology is influenced by female sex steroids and, hence, would alter its morphology in a similar manner as the endometrial epithelium. Therefore it is not surprising to detect bulging, excrescences, and sloughings of the apical aspects of epithelial cells in a manner similar to that reported previously (Gilloteaux et al, 1992(Gilloteaux et al, , 1993a and similar to that which has been noticed in the endometrium of the Syrian hamster (Gilloteaux and Steggles, 1986) and human (Wessel, 1960;Wetzstein and Wagner, 1960;Wynn and Wooley, 1967) under the periodic or chronic influence of sex hormones. In addition to influencing functional epithelial morphology of the gallbladder, sex steroids may also affect cystic duct motility and metabolism.…”

Apical excrescences in the gallbladder epithelium of the female Syrian hamster in response to medroxyprogesterone

“…8) do not show characteristic mucinous granules of goblet cell surfaces, thus leading to the speculation that this could be a remnant of cell discharge or an intermediate stage of the surface healing process. Apical excrescences demonstrated in this report are homolgous to the apocrine-like secretory events observed in the hamster (Gilloteaux and Steggles, 1986) and human endometrium (Wessel, 1960;Wynn and Wooley, 1967). Interestingly, similar events are observed in human gallbladder (Lopez et al, 1982) and in teleostean gallbladders (Viehberger, 1982).…”

Ultrastructural Changes in Human Endometrium at Different Phases of the Menstrual Cycle and Their Functional Significance

“…nucleolus [Clyman, 1963a, b;Terzakis, 1965;Wynn and Woolley, 1967;More and McSeveney, 1980] and of other organelles, particularly lysosomes and mitochondria Merker et al, 1968;Armstrong et al, 1973;Worth and Lucas, 1978;Coaker et al, 1982], Some other authors have described the changes occur ring during the menstrual cycle [Wessel, 1960;Wynn and Harris, 1967;Sengel and Stoebner, 1970a, b;Hopwood and Levison, 1976;Davie et al, 1977], Each of the above authors dealt with only one aspect of the endometrial cells, but a complete account of the whole cycle has not been given. There fore a review of the structural features and of their functional implications for the human endometrium in the light of the recent knowledge of the functioning of organelles will provide insights into various disorders, par ticularly those associated with the use of contraceptives.…”
