One of the best known crustacean hormones is the crustacean hyperglycemic hormone (CHH). However, the mechanisms involved in hormone release in these animals are poorly understood, and thus constitute the central objective of the present study. Different groups of crustaceans belonging to diverse taxa (Chasmagnathus granulata, a grapsid crab and Orconectes limosus, an astacid) were injected with serotonin, fluoxetine, or a mixture of both, and glycemic values (C. granulata and O. limosus) and CHH levels (O. limosus) were determined after 2 h in either submerged animals or animals exposed to atmospheric air. Both serotonin and fluoxetine caused significant hyperglycemia (P<0.05) after injection into the blood sinus of the two species, an effect enhanced... |

ABSTRACT: The primary hyperaldosteronism, an endocrine disease increasingly identified in cats, is characterized by adrenal gland dysfunction that interferes with the renin-angiotensin-aldosterone system, triggering the hypersecretion of aldosterone. Pathophysiological consequences of excessive aldosterone secretion are related to increased sodium and water retention, and increased excretion of potassium, which induce hypertension and severe hypokalemia, respectively. The most common clinical findings in cats include: polydipsia, nocturia, polyuria, generalized weakness, neck ventroflexion, syncope, anorexia, weight loss, pendulous abdomen and blindness. Diagnosis is based on the evidence of hormonal hypersecretion with suppression of renin release,... |

The aim of the present study was to observe the changes in the muscle tissue of rats after application of growth hormone (GH) and performing a strength training protocol (ST). In total, 40 male Wistar rats, 60 days old, were used, divided into four groups: control (C), control and application of GH (GHC), strength training (T), and strength training with the application of GH (GHT). The physical training protocol (PT) was composed of four series of 10 jumps in water, 3x/week, with an overload of 50 % of body weight for four weeks. GH was administered intraperitoneally at a dose of 0.2 IU/Kg to the GHC and GHT groups and saline (0.9 % sodium chloride) to the C and T groups. After four weeks of PT, the animals were euthanized and samples taken from the... |

Alternative methods to the utilization of laboratory animal blood and its by-products are particularly attractive, especially regarding hamsters due to their small size and difficulties in obtaining serial blood samples. Steroid hormone metabolite quantification in feces, widely used in studies of free-ranging or intractable animals, is a non-invasive, non-stressor, economical, and animal saving technique which allows longitudinal studies by permitting frequent sampling of the same individual. The present study was undertaken to determine the suitability of this method for laboratory animals. Estradiol and progesterone metabolites were quantified by radioimmunoassay in feces of intact, sexually mature female Syrian hamsters during the estrous cycle... |

Serial clinical, colpo-cytological and endocrinological examinations of two five-year-old females of the crab-eating dog (Cerdocyon thous), from the RIOZOO Foundation in the State of Rio de Janeiro - Brazil, were carried out over a 10-month period. Clinically healthy animals were kept in sand substratum enclosures, located 500m apart from each other. They were each housed with two males. The colpo-cytological technique employed for Cerdocyon thous used methods similar to those developed for domestic bitches. Unlike domestic dogs, blood cells were absent in all phases of the estrus cycle, including the pro-estrus phase. Differentiation of each type of vaginal cells during the estrus cycle phases in this species follows the same patterns shown by domestic... |

Proteolytic enzymes of hepatopancreas of six species of peneids (Penaeus kerathurus, P. japonicus, P. monodon, P. stylirostris, P. merguiensis and P. vannamei ) have been studied. Some of their physiological variations have been characterised. Increase in acclimation temperature of crustaceans enhances increase of specific activities of proteases. Variations of salinity does not modify specific activities, nor quantities of trypsin, nor electrophoretic patterns of these different proteases. |
