The Administration of Cortisone to Female B6A Mice During their Immune Adaptive Period Causes Anovulation and the Formation of Ovarian Cysts

Autor: Sandra D. Michael, Keith Tung, Saureen Shah, Saichol Kunaporn, John C. Chapman, Soohong Min

Publikováno v: American Journal of Reproductive Immunology. 48:184-189

Problem Female mice that are injected with estradiol-17beta (E2) and testosterone during the 7-day immune adaptive period are infertile at adulthood. To determine whether the resultant infertility can be caused by steroids other than estrogens/ andro

The Differential Effect of Injecting Estradiol-17beta, Testosterone, and Hydrocortisone During the Immune Adaptive Period on the Fertility of Female Mice

Autor: Saichol Kunaporn, Sandra D. Michael, John C. Chapman, Soohong Min, Anastasia Kaiki-Astara, Saureen Shah

Publikováno v: American Journal of Reproductive Immunology. 46:288-297

PROBLEM: Female mice injected with estradiol-17β (E 2 ) and testosterone during the immune adaptive period are infertile as adults. Study 1 examined the effect of the day of injection of E 2 and testosterone on the incidence of infertility in two st

Female House Mice Develop a Unique Ovarian Lesion in Colonies That Are at Maximum Population Density

Autor: John C. Chapman, Mary Ann Pawlikowski, Norie Yasukawa, Sandra D. Michael, John J. Christian

Publikováno v: Proceedings of the Society for Experimental Biology and Medicine. 225:80-90

Colonies of house mice reach maximum population density in 120–180 days, irrespective of cage size and initial number of colonizing animals. Reproduction ceases because the females become aggressive and unreceptive to mating. The aggressive behavio

Alteration of Cytokine Production in Follicular Cystic Ovaries Induced in Mice by Neonatal Estradiol Injection

Autor: ROHINI R. DESHPANDE, JOHN C. CHAPMAN, SANDRA D. MICHAEL, MING-DER Y. CHANG

Publikováno v: American Journal of Reproductive Immunology. 44:80-88

Problem Neonatal estradiol injections in mice lead to follicular cystic ovaries that are similar to ovaries in patients with polycystic ovarian syndrome (PCOS). The present study examined ovarian cytokine production following neonatal estradiol injec

The Anovulation in Female Mice Resulting from Postnatal Injections of Estrogen is Correlated with Altered Levels of CD8+ Lymphocytes

Autor: Sandra D. Michael, John C. Chapman, Rohini R. Deshpande

Publikováno v: American Journal of Reproductive Immunology. 38:114-120

PROBLEM: Injections of estradio1-17β (E 2 ) are known to both induce anovulation and alter lymphocyte maturation in female mice. The current study examined whether the two events are related. METHOD OF STUDY: Female (C3H/HeJ x 129J)F 1 (C31) mice we

Changes in Mitochondrial and Microsomal 3β-Hydroxysteroid Dehydrogenase Activity in Mouse Ovary over the Course of the Estrous Cycle1

Autor: Sandra D. Michael, John C. Chapman, Timothy B. Waterhouse

Publikováno v: Biology of Reproduction. 47:992-997

3 beta-Hydroxysteroid dehydrogenase (HSD) is located in the endoplasmic reticulum and mitochondria. To determine whether the separate enzymes play different roles in steroidogenesis, the specific activity (SA) of both were measured at four different

Cell-mediated and neural control of morphostasis

Autor: Presl J, Sandra D. Michael, Antonín Bukovský

Publikováno v: Medical Hypotheses. 36:261-268

Morphostasis refers to the maintenance of the differentiated state of tissues in an adult individual and it represents a basal event of homeostasis and the organism's existence. Most of the cells in the body are arrested in their differentiation at a
