The expression of the estrogen receptor alpha (ERα) was investigated in domestic cat ovaries and uteri by mean of immunohistochemistry, using monoclonal antibody against ERα. The stages of the oestrous cycle were determined by vaginal cytology and serum steroid levels which were taken before operation. In the uterus, positive staining was found in the nuclei of all uterine cell types in different proportions and staining intensity. During oestrous, the staining intensity and the proportion of positive cells were highest in the epithelium (both the surface epithelium and the glandular epithelium) as well as in the myometrium. At dioestrous, ERα expression …

An immunohistochemical examination of aborted bovine tissues, collected from two dairy farms that had a high abortion rate (7%), detected the organism Neospora caninum (NC). Five out of 12 aborting cows (41.7%) were seropositive to NC using a competitive ELISA test. Neospora-tachyzoites were detected in the placenta of a seropositive aborting cow. Neither NC parasites nor cysts were detected in other fetal tissues. The identification of the Neospora-parasite and a high percentage of Neospora seropositive aborting cows, suggested NC as the possible cause of abortion. This is the first identification of the NC parasite in Thailand.

Ovarian steroid hormones are known to be an important modulator in the regulation of reproductive function in the female. The levels of oestrogen and progesterone have been well documented whilst interacting during the entire oestrous cycle but their specific receptors in the target cells are less understood. Therefore, a comparative study of oestrogen (ER) and progesterone receptors (PR) at certain oestrous stages should be of help in the prediction of their interaction in specific uterine compartments. Tissue samples were collected at different stages of the oestrous cycle: oestrus (n=3), early dioestrus (n=3) and late dioestrus (n=3). They were fixed in …
