| La boutargue est constituée par les ovaires salés et séchés des mulets à grosse tête (Mugil cephalus) et de la courbine (Argyrosomus regius) représente une ressource importante pour la région de Nouakchott et pour la Mauritanie. Pour déterminer la valeur énergétique dans les boutargues, nous avons effectué des dosages des protéines, des glucides, des lipides et des études analytiques des acides gras et des lipides. Les analyses ont révélé que la boutargue contient, par rapport aux autres éléments d’énergie, très peu de glucide : 3,29% dans la boutargue du mulet et 1,95% dans celle de la courbine. Alors que les teneurs en protéines et lipides sont importantes et sont respectivement de 44,44% et 31,68% dans la boutargue du mulet et de 55,11% et 15,86% dans... |

| 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... |

| 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 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... |

| The species, like other members of the Family Sparidae, has a hermaphroditic phase in its sexual development, affecting the population partially during the first period of life. The sexual differentiation mechanisms have been inferred by the way of macroscopic characterization and proportionality of the different stages observed during the first five year classes. The highest proportion of specimens with bisexual gonads is observed during the third year of life: from the macroscopical point of view, both sexes are equally developed or with predominance of the masculine crest; microscopically, both are functional and synchronous. The masculine portion demostrate a normal expulsion of germ cells and in the ovaric part post-ovulatory and atretic follicles... |

| 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... |

| Batch fecundity and spawning frequency of Argentine hake inhabiting Patagonian waters south of 41° S were estimated using monthly samples collected during the December 2000-March 2001 reproductive season and at the end of the March 2002 spawning period. Batch fecundity was fitted to a power function of total length and a linear function of ovary-free female weight with values ranging between 100,000 (32 cm total length) and 2,300,000 (87 cm total length) hydrated oocytes. Batch and relative fecundity showed variations during the spawning season with a marked decrease towards the end of the reproductive period (March). The spawning frequency, which ranged between 0.10 and 0.15, was estimated from the proportion of females with day-1 postovulatory follicles... |

| 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... |

| ABSTRACT Gossypol, a phenolic compound produced by the pigment glands of cotton, is known to affect male reproduction. In females, exposure to gossypol has been associated with interference with the estrous cycle and embryo development. In laying hens fed cottonseed, gossypol was found to reduce egg production and weight and to cause discoloration of the egg yolk and/or albumen. It is probable that gossypol directly affects ovarian follicles, but this has not been confirmed experimentally yet. Thus, the aim of the present study was to determine if gossypol affected cultivated ovarian follicles of the chicken. Ovarian follicles of adult female chickens were cultivated with different concentrations of gossypol (0, 5, 10 and 20 μg/mL) and classified according... |
