The Effects Of 712-Dimethylbenz (A) Anthracene On Ovarian Steroidogenesis And Uterine Growth In The Mouse, Jeffrey Lynn Clark
The Effects Of 712-Dimethylbenz (A) Anthracene On Ovarian Steroidogenesis And Uterine Growth In The Mouse, Jeffrey Lynn Clark
Biological Sciences Theses & Dissertations
It has been previously demonstrated that 7,12-dimethylbenz(a) anthracene (DMBA) is an initiator of ovarian granulosa cell tumors. It is also known that DMBA leads to destruction of primordial oocytes, and that tumor induction may involve the interaction of pituitary gonadotropins. However, the effects of DMBA on ovarian steroidogenesis and uterine growth in relation to the tumorigenic process have not been investigated. Therefore, the present study was conducted to examine these parameters using adult C57Bl/6N mice treated in proestrus and diestrus II with 0.1 ml corn oil with or without 1.5 mg DMBA and killed 44 hours later. The uteri and …
Structural Studies Of Preimplantation Rabbit Embryos Using Ftir Atr, Amy R. Moler-Booth

FTIR was used in conjunction with a surface selective technique, known as attenuated total reflectance (ATR), to study the infrared spectra of preimplantation rabbit embryos. The rabbit embryos ranged in aged from 3 to 6 days. Since an embryo is mostly water, deuteration of the embryo was necessary to eliminate the intense water background present in the mid-infrared region. A set of spectral standards were tested, in order to identify the bands seen in embryo spectra. By analyzing and comparing the spectra from 3, 4, 5 and 6 day embryos, differences could be noted. In particular, bands defined as Amide …
