In the first case the standing stock of atretic
follicles (Ia) was measured as prevalence (proportion of fish containing alpha atretic
follicles) and relative intensity (Ia/whole body weight g) as described previously (Witthames and Greer-Walker, 1995).
The occurrence of oocyte atresia in spent oocytes or oocytes that had been spawned was determined by counting the number of atretic
oocytes present in the tissue sample of whole oocytes.
or spent No spermatogenesis occurring but some residual spermatozoa in shrunken lobules and ducts.
The occurrence of atretic
oocytes was highest in May and became lower as the season progressed until the end of the spawning season.
While maintaining the balance, it has shown promising results in preserving the number of primordial, primary and secondary follicles; however, it has not been able to reduce the number of atretic
follicles within CYP exposed ovaries.
According to HE staining of slices of the right ovary, it was found that the ovarian tissue was destroyed and there were few structurally complete follicles and abundant atretic
follicles in the 0 mg/kg curcumin group compared to the normal control [Figure 1];[Table 3].
Diagnosis of germinal cells in different stages of oocyte development, postovulatory follicle complex (POC) and atretic
ovarian follicles of Serrasalmus marginatus on the Parana River floodplain.
Sections were examined by using calibrating ocular graticule for the number and diameter of primary, antral and atretic
follicles and number and size of the ovarian cysts, by the method described earlier.
However, these authors reached their conclusion by analyzing the oocytes stages present, tunica appearance, and presence or absence of atretic
, rather than attempting to count cell numbers per stage, as was done in the present study (McBride, personal communication, May 19, 2016).
It has been suggested that these cysts arise from an abnormal response of atretic
follicles in the ovaries to circulating Beta-hCG, which may or may not be high.
2) Papules or nodules around aplasia cutis may be associated with more significant neural tube anomalies, including congenital ectopic meningeal tissue, also termed atretic
or rudimentary meningoceles.
In the 4 individuals classified as late-stage transitional fish, degenerating or atretic
oocytes in the presence of maturing testicular tissue at differing stages of development were observed (Fig.
