[Methods]30 SD rats were randomly divided into 3 groups according to their weight and were exposed to toluene of different concentrations(0,130 and 1 300 mg/m3 respectively) for 2 and 24 hours,then the serum and ovary of the rats were collected; Radioimmunoassay was applied to determine the sex hormone(E2 and P4) in serum; the ovary samples were stained with HE and the number of follicles was calculated.
A trend to increase in the ovarian relative weight and mature egg size with age has been revealed.
Two species with a wide range (perch and bream) demonstrated a tendency to decrease in the ovarian relative weight and increase in the definitive oocyte weight in females of populations living in the geographical center of the range.
The thermostable fraction of serum samples from patients with ovarian, uterus, and breast cancers and benign ovarian tumor was analyzed using two-dimensional electrophoresis combined with MALDI-TOF(-TOF)-mass spectrometry.
Of them, α-1-acid glycoprotein and clusterin are expressly down-regulated in breast cancer, whereas transthyretin is decreased specifically in ovarian cancer.
Frequencies of Single-Nucleotide Polymorphisms and Mutations in the BRCA1 Gene in Patients with Hereditary Breast or Ovarian Can
The ovary is trilocular with axile placenta, and the ovules are bitegmic, tenuinucellate, and anatropous.
A gradual increase in the content of the active and storage forms of the hormones from the ovary to the ovule was revealed.
Effect of Estradiol Dipropionate on Protein Synthesis in Oocytes and Ovary of the Sea Urchin Strongylocentrotus intermedius at D
We studied protein synthesis in the oocytes and ovary of the sea urchin Strongylocentrotus intermedius at different stages of the reproductive cycle after treatment with estradiol dipropionate.
After estradiol dipropionate treatment, the inhibitors of protein synthesis, puromycin and actinomycin D, decreased the intensity of 3H-leucine incorporation in the oocytes and protein synthesis in the ovary.
