| Locally, mammalian herbivores may have significant effects on the abundance and fitness of plant species. This study focuses on the interaction between cuises (Microcavia australis-Rodentia-) and creosote bush (Larrea cuneifolia -Zygophyllacea-), which is a widespread and ecologically dominant evergreen shrub in the Monte Desert of Argentina. Specifically, we examined the probability of plants being gnawed by cuises in relation to branch diameter and distance to cuis colonies. Additionally, we assessed the effect of gnawing by cuises on branch condition, production of flowers and fruits and branch survival. In general, gnawing by cuises negatively affects creosote bush plants. The likelihood of being gnawed is higher for branches of smaller diameter and in... |

| ABSTRACT: The aim of this research was to study the development of the lung in Galea spixii , by gross anatomy, histological analysis and immunohistochemical techniques. Totally, 8 fetuses were used and allocated into three groups of age: Group I (33-35 days), Group II (38-40 days), and Group III (43-45 days) with given crown-rump - CR lenghts. According to the gross morphology, there were no differences in relation to the lung morphology among groups. In relation to lung maturation, the Group I showed early formation of the bronchi and bronchioles, which were richly surrounded by mesenchyme and small blood vessels, typical features of the pseudoglandular stage. Individuals from Group II showed higher amounts of tubular formations in the lung parenchyma... |

| Anaphylactic shock can be defined as an acute syndrome, and it is the most severe clinical manifestation of allergic diseases. Anaphylactoid reactions are similar to anaphylactic events but differ in the pathophysiological mechanism. Nitric oxide (NO) inhibitors during anaphylaxis suggest that NO might decrease the signs and symptoms of anaphylaxis but exacerbate associated vasodilation. Therefore, blocking the effects of NO on vascular smooth muscle by inhibiting the guanylate cyclase (GC) would be a reasonable strategy. This study aimed to investigate the effects of NO/cGMP pathway inhibitors methylene blue (MB), Nω-nitro-L-arginine methyl ester hydrochloride (L-NAME), and indigo carmine (IC) in shock induced by compound 48/80 (C48/80) in rats. The... |

| The Atlantic Forest small mammal land fauna, except bats, and the abiotic factors that might have an influence on its composition, were studied in the Itapevi County, State of Sao Paulo, a forested region, partly altered by antropic action, from January, 1995 to June, 1996. The trapping effort consisted of 2,888 trap-nights, resulting in a 4.6% trapping success and consisted of monthly trappings, for five consecutive days. During this period, 134 specimens were captured, of which 46.3% were Didelphimorphia and 53.7% were Rodentia. Eleven species were registered: two Didelphimorphia: Didelphis marsupialis (Linnaeus, 1758) and Marmosops incanus (Lund, 1841), and nine Rodentia: Akodon cursor (Winge, 1887), Bolomys lasiurus (Lund, 1841), Oxymycterus hispidus... |

| ABSTRACT The aim of this work is study the laparoscopic ovum pick-up (LapOPU) technique in spotted paca, describing surgery details, complications and oocyte recovery rate. Nine healthy adult non-pregnant captive females were used, in a total of 39 procedures. When the surgical plane of anaesthesia was achieved, the females were positioned at 20º Trendelenburg. Three 6mm trocars were placed on right and left inguinal and hypogastric regions. Abdomen was inflated with CO2 and the intra-abdominal pressure was stablished in 10mmHg. Follicular punctures were performed moving the ovaries with atraumatic forceps. For punctures, an 18-gauge 3.5 inch long needle attached to a vacuum system with pressure not exceeding 65mmHg was used. Oocytes were recovered into... |

| ABSTRACT The pelvimetry consists of the metric determination of the pelvis dimensions and its use is directly related to the reproduction. The cartilage closure time of the ossification centers varies according to the bone, some closing already in the uterine life and others remaining present for many years. The objective was to evaluate, radiographically, the pelvic diameters by pelvimetry during the first 24 months of life in pacas, the second lagest Brazilian rodent and an animal that has shown big recent scientific interest, aiming the estimated age determination. Twelve pacas were used, which were monthly radiographed up from birth until 24 months old, with the animals anesthetized. The pacas are dolicopelvic animals and with pelvis presenting strong... |
