| The morphology of the reproductive tract of Podisus nigrispinus (Dallas) females fed with Alabama argillacea (Hübner) larvae, artificial diet, Tenebrio molitor L. larvae or Musca domestica L. larvae were studied. The reproductive tract of females of this species presented yellow coloration and independent of the diet, each ovary had seven ovarioles joined through terminal filaments and forming a bunch shape structure. The histological data revealed that the ovary of P. nigrispinus was of meroistic telotrophic type, with each individual ovariole divided in a terminal filament, a tropharium (trophic chamber), a vitellarium, and a pedicel. The prey type affected the development and morphometry of these structures. Females of P. nigrispinus fed with 3rd or 5th... |

| The multidrug resistance (MDR) phenotype is associated with the expression of P-glycoprotein (Pgp), coded by the multigenic mdr family. Mice present the isoforms mdr1 and mdr3, which are responsible for multidrug resistance, and mdr2, that is involved in the transport of phospholipids. mdr1 expression has more recently been associated also with the secretion of steroid hormones. This work presents an RT-PCR analysis of the expression of mdr isoforms, in several organs of mice during different phases of the estrous cycle. Additionally, females were ovariectomized, submitted to different hormone treatments, and their uterus was analyzed for the expression of mdr isoforms. The results show that in the adrenal gland and ovaries mdr1 is the main isoform during... |

| The present work analyses and describes Merluccius merluccius ovarian cycle in the Bay of Biscay as an example of partial spawner. Three methods were employed: a macroscopic examination of about 10,000 ovaries -- a cytologic and histologic study -- an investigation of the size structure of the oocytes population of 63 ovaries. The author developed an original mathematical method for serial spawning demonstration. He demonstrates that hake is a partial spawner: a female usually rapidly spawns 4 or 5 times without ovaries rest. On this basis, he gives a new reference scale of the maturity stages of the ovarian cycle: after developing (II), ripe (III), running (IV), the partly spent ovary is named (II+); the repetitive sequence III-IV-II + characterize serial... |

| The present study was designed to determine the morphological and histological variations in the female palm squirrel's reproductive organs which inhabit croplands of central Punjab. 16 specimens were collected from 3 different locations of Faisalabad district during different months in order to collect their ovaries samples in order to determine the breeding phenology of this species. Body weight and external body measurements were recorded. Two adult females were autopsied each month and their ovaries were extracted. Tissue were prepared by the tissue paraffin technique and stained by H&E. Seasonal variations in the follicular size and shape were observed. Statistical analysis revealed that values of all parameters of ovaries were significantly... |

| In developing countries, herbal medicines have continued to remain significant and readily patronized. Numerous plants have been used historically to reduce fertility and modern scientific research has confirmed antifertility effect in some of the herbs tested. To investigate the effects of Abrus precatorius (AP) on the histology of the ovary, oviduct and uterus of female Sprague-Dawley (S-D) rat. A total of 40, 68 week old 4-day cycling female S-D rats were used. They were divided into the treatment, control and reversibility groups. The treatment and reversibility groups were fed oral AP seed extract (50 mg/kg b.w) for 32 days. A fraction of the rats in reversibility group was treated with distilled water for another 32 days. The control group were used... |

| The present study had the objective of analyzing morphometrically the occupied area by the ovarian follicles in ovaries of pinealectomized female rats. To do so, 24 albino female rats (Rattus norvegicus albinus) were used, which were equally divided in the following groups: Group I sham-pinealectomized rats and kept in the light/dark cycle (12/12 hours), for three months; Group II pinealectomized rats and kept in the light/dark cycle (12/12 hours), for three months; Group III pinealectomized rats and kept in the absence of light for three months; Group IV sham-pinealectomized rats and kept in the absence of rats for three months. The results showed that the groups I and IV presented, respectively, average of 19,00 and 25,00, while groups II and III... |

| The gonadal development assessment is a fundamental work in researching the reproduction of Peprilus medius, on the way to understand its population dynamics and to achieve a sustainable management of its fisheries. The diagnosis based on morphochromatic features is the quicker, more practical and cheaper method, and properly validated, it may be an accurate procedure. This is particularly useful in researches when it is required to provide prompt and accurate information to support decision-making for fisheries management, and during long-term fisheries monitoring to detect changes in reproductive patterns due to environmental anomalies. These are issues of concern in P. medius and other fishery resources. In this context, a scale that describes the... |
