bicinctores: (1) No yolk deposition (quiescent); (2) Early yolk deposition with basophilic granules present in the ooplasm; (3) Enlarged preovulatory follicles (> 4 mm); (4) Oviductal
Four stages were present in the ovarian cycle (Table 1): (1) quiescent, no yolk deposition present; (2) early yolk deposition, with basophilic yolk granules in the ooplasm; (3) enlarged ovarian follicles > 4 mm diameter; (4) oviductal
eggs present in the oviducts.
A female in June contained damaged oviductal
eggs which were not counted.
Four stages were present: (1) quiescent (no yolk deposition); (2) enlarged follicles > 5 mm diameter; (3) oviductal
eggs or embryos; (4) oviductal
eggs and yolk deposition for a subsequent clutch.
Gross pathologic classifications were designated as follows: birds presenting with ovarian tumors only (class 1), those presenting with oviductal
and ovarian tumors (class 2), those with ovarian and oviductal
tumors that metastasized to the gastrointestinal tract (class 3), those with ovarian and oviductal
tumors that metastasized to the gastrointestinal tract and other distant organs (class 4), those with oviductal
tumors only (class 5), those with oviductal
tumors that metastasized to other organs with no ovarian involvement (class 6), and those with ovarian tumors that metastasized to other organs with no oviductal
involvement (class 7), including birds with gastrointestinal tumors and no reproductive involvement (gastrointestinal only) and those with no tumors (normal).
The zygotes were cultured in synthetic oviductal
fluid with a minor modification (mSOF) (Holm et al.
Females were classified as previtellogenic (without vitellogenic follicles), vitellogenic (with yellow follicles [greater than or equal to] 2 mm in diameter), and gravid (with oviductal
In this sense, the inner surface of the oviduct, as well as the oviductal
fluid have drastic effects on the aforesaid biological processes.
Enlarged follicles (> 5 mm) and/or oviductal
eggs were counted.
eggs or enlarged ovarian follicles (> 4 mm length) were counted.
4) In the early stages of disease before the tumor has spread, it may be possible to identify eosinophilic cytoplasmic granules of ovalbumin, which are characteristic of oviductal
In bovine oviductal
fluid, there are both sulfated GAGs, including chondroitin sulfate (CS), dermatan sulfate (DS) and heparin (HP), and the non-sulfated GAG hyaluronic acid (HA) (Hileman et al.
