Abstract
Preservation of preantral follicles becomes very important to ensure follicle quality at the onset of cryopreservation or in vitro culture. However, for domestic animals, the ovarian donor of preantral follicles for in vitro studies is commonly encountered far away from reproduction laboratories. We investigated the effectiveness of coconut water and Braun-Collins solutions on the preservation of goat preantral follicles. At the slaughterhouse, the ovarian pair of each animal was divided into 19 fragments. One ovarian fragment was immediately fixed (Control - Time 0). The other 18 fragments were randomly distributed into tubes containing 2 mL of coconut water or Braun-Collins solution at 4 degrees, 20 degrees or 39 degrees C and then stored for 4, 12 or 24 h. Histological analysis showed that the storage of ovarian fragments in coconut water and Braun-Collins solutions at 20 degrees or 39 degrees C for 12 or 24 h significantly reduced (P < 0.05) the percentage of morphologically normal preantral follicles when compared with the control. However, storage in coconut water at 20 degrees C for 4 h and in both solutions at 4 degrees C kept the percentage at control values. Ultrastructural analysis of follicles exposed to the stated conditions confirmed the integrity of preantral follicles stored at 4 degrees C in Braun-Collins and coconut water solutions for up to 12 and 24 h, respectively. Reduced cellular metabolism at 4 degrees C may explain why the best preservation of preantral follicles was at 4 degrees C, which may suggest a useful method for ovary transport in the future.

Abstract
Malaria parasites digest haemoglobin and detoxify the free haem by its sequestration into an insoluble dark-brown pigment known as haemozoin (Hz). Until recently, this pigment could be found only in Plasmodium parasites. However, we have shown that Hz is also present in the midgut of the blood-sucking insect Rhodnius prolixus [Oliveira et al. (1999) Nature 400, 517-518]. Here we show that Hz synthesis in the midgut of this insect is promoted by a particulate fraction from intestine lumen. Haem aggregation activity is heat-labile and is inhibited in vitro by chloroquine (CLQ). Inhibition of Hz formation in vivo by feeding insects with CLQ leads to increased levels of haem in the haemolymph of the insect, which resulted in increased lipid peroxidation. Taken together, these results indicate that a factor capable of promoting Hz crystallisation is present in R. prolixus midgut and that this activity represents an important physiological defence of this insect against haem toxicity.

Abstract
Some triterpenes and iridoids were previously isolated from the stem bark of Himatanthus sucuuba. The latex from Himatanthus sucuuba is used in popular amazonian medicine as an anti-inflammatory remedy. Fractions of the latex were pharmacologically evaluated with a view to verify this popular use in the carrageenan-induced rat paw edema and in the acetic acid-induced mouse constriction tests. The hexane fraction inhibited the edema formation by 35.9% at a dose of 200 mg/kg (p.o.) but no activity was observed at 100 mg/kg (p.o.). The triterpenes present in the hexane fraction were identified as lupeol acetate, alpha-amyrin and lupeol cinnamates. The fraction containing only cinnamates inhibited the edema and the abdominal constrictions by 50-40% and 57.9%, respectively, at 100 mg/kg (p.o.). Among all the fractions studied, the fraction containing only cinnamates showed the greatest anti-inflammatory activity which suggests that these compounds were responsible for the previously described activity of the crude extract.

Abstract
The inflammatory response induced by the implant of a suture thread in Peripatus acacioi muscle was characterized under light and transmission electron microscopy (TEM). After 24 and 48 h granulocytes were observed migrating through the connective tissue toward the suture thread. These cells contain cytoplasmic eosinophilic granules as well as free granules near to the thread. There were few spherule cells with eccentric smooth kidney-shaped acidophilic nuclei and basophilic granules. Cells with intermediary characteristics as well as cells with a central basophilic nucleus with scarce acidophilic cytoplasm devoid of granules were also found. Under TEM, the granulocytic coelomocytes show small and homogeneous electron dense granules, while the spherule cells possess spherules that can be heterogeneous, granular, or with myelin figures. An acute induced inflammatory process is described for the first time in Onychophora and contributes to the scarce available literature on the function of the coelomocytes within this group.

Abstract
The femoral or cloacal region of many species of lizards and amphisbaenians exhibits epidermal glands. The pores of these glands are plugged with holocrine solid secretions that serve as semiochemical sources. Many authors assume that these glands are mainly associated with reproduction and demarcation of territory. The structure of precloacal glands in Amphisbaena alba was previously studied by Antoniazzi et al. (Zoomorphology 113:199-203, 1993; J. Morphol. 221:101-109, 1994). These authors suggested that as the animal moves inside tunnels, the secretion plugs are abraded against the substrate, releasing a secretion trail. Some aspects of the plug were difficult to interpret in fine sections due to the dense and brittle nature of the plug. The morphology of the trail, and the manner of deposition on the substrate, have never been reported. This study presents a primarily scanning electron microscopic description of A. alba precloacal glands and of the secretion plugs. It also demonstrates experimentally the formation of the trail and its fine morphology. The results show that when the plugs scrape against the substrate, their constitution helps them to fragment into tiny pieces, which are spread on the ground, thus forming a trail. Each one of the fragments corresponds to a secretion granule of the precloacal gland's secretory cells. In this way, the trail might have an extensive area for volatilization of semiochemicals, constituting an efficient means of intraspecific communication inside the tunnels.

Abstract
The purposes of this study were to estimate the population of caprine preantral follicles, and to evaluate quantitatively and qualitatively the efficiency of a specific mechanical method for the isolation of preantral follicles from mixed breed goats at different reproductive stages. On average, 37,646+/-4277 preantral follicles were present in goat ovaries, and 13,631+/-2399 preantral follicles were obtained after isolation. The number of preantral follicles isolated or in situ was not significantly affected by the reproductive stage. The mean recovery rate per ovary ([number of isolated follicles/number of in situ follicles] x 100) of isolated follicles was 36.2%. The distribution of follicles in situ was 67.8% primordial, 25.8% primary and 6.4% secondary; the respective distribution after isolation was 93.8%, 5.2% and 1.0%. In this study, many polyovular follicles were also observed, mainly in prepubertal goat ovaries. Histological analysis showed that few preantral follicles were atretic in situ (4.83%+/-0.35) or after the isolation procedure (4.67%+/-0.65) in the three reproductive stages. The percentage of atretic follicles was not affected either by the mechanical method or by the reproductive stage. It is concluded that a large number of preantral follicles can be successfully isolated mechanically, with a high recovery rate and a low rate of follicular atresia, irrespective of the reproductive stage of the caprine female.

Abstract
In Chile swine trichinosis has presented a progressive decreasing in the last two decades of XX century. T. spiralis pig infection descended from an average of 0.683 per 1000 in 1980-1984 to 0.315 in 1985-1989 and to 0.115 in 1990-1996. In the particular case of Metropolitan Region this decreasing has been more marked: from an average of 0.058 per 1000 in 1990-1994 to 0.003 in 1995-1999. Between the end of June 1999 and middle January 2000 in Metropolitan Region abattoirs T. spiralis was detected in 15 (4.9%) out of 306 swine from two pigsties located in El Monte (E.M.) and Padre Hurtado (P.H.) 45 and 30 km south-west from Santiago. In the same period another four pigs from the same premises were found infected in abattoirs of other regions. During inspection visits it was stated that both pig farms had deficient sanitary conditions. Phototrichinoscopy was positive in three out of five Rattus norvegicus collected in E.M. In pigsty PH the examination of diaphragm samples of 25 dogs and 17 cats resulted negative. In the premises originating T. spirali infected swine the Metropolitan Environmental Health Service Abattoirs Program carries out an epidemiological vigilance consisting in the follow-up of animals destined for slaughtering in order to initiate prophylactic actions oriented to eliminate eventual sources of trichinosis infection for human and rearing pigs.

Abstract
The present work investigated the effect of the interval of serial sections of ovarian tissue on the number of isolated preantral follicles in the goat. Goat ovaries were cut in the tissue chopper at eight different intervals. The quality of isolated follicles were evaluated by histology and transmission electron microscopy. Best results were obtained when the ovaries were cut in the tissue chopper at intervals of 75.0 microm (9664 preantral follicles per ovary). Histochemical and ultrastructural analysis showed that the follicular morphology was preserved after mechanical isolation as demonstrated by the normality of oocytes and granulosa cells as well as by preservation of basement membrane. The percentages of isolated primordial, primary and secondary follicles were 96.3%, 2.5%, and 1.2% and their average diameters were 21.5, 34.7 and 65.3 microm, respectively. It was concluded that the interval of serial sections of ovarian tissue in the tissue chopper affects the number of isolated preantral follicles, and that the follicles remained intact after mechanical isolation in goats.

Abstract
The existence of phagocytes in the Amphioxus is a matter of debate since early studies of Metchnikoff, who could not induce inflammation in this animal. To reinvestigate this important phenomenon, we sectioned the distal portion of the animal and analyzed, by morphological methods, the presence of phagocytes in the wound. The analysis of the wound by optical and electron microscopy did not detect cells with morphological characteristics of phagocytes in it. The wound is completely covered by the external cuticle of the animal 24 hr after the lesion was made. A second section of the animal leads to abnormal healing of the lesion. The insertion of a surgical silk thread in the muscle of the animals results--after 13 days--in a collection of cells surrounding the foreign body. The ultrastructural analysis of these cells showed they are endothelial cells rather than specialized phagocytes. Yet, the Amphioxus is able to mount an allograph rejection when the animals are tied together by suture. This intriguing capacity of the Amphioxus to cope with tissue healing, infection, and other pathologies without phagocytes is discussed.

Abstract
With the objective of measuring alveolo-capillary permeability, a diprophylline solution (molecular weight 254 D) was instilled as a bolus. Instillation was performed through distallized impacted fiber bronchoscope and 3 normal volunteers and 3 patients with pulmonary fibrosis were evaluated. Blood samples were collected at regular intervals with subsequent pharmacokinetic study, mainly aimed at determining absorption kinetics. This technique enabled us to distinguish the two groups of individuals which had different absorption rates. In controls, kinetics apparently followed a simple, one compartment model for absorption, which was slower and occurred to a lesser extent. Patients with a pulmonary fibrosis had a faster and higher degree of absorption, with a larger plasma Cmax. In the latter group two-compartment kinetics for absorption was found. We conclude that absorption kinetic parameters can disclose data on structural integrity of epithelia and possible lesions of the lung interstitium.

Abstract
Congenital dislocation of the knee (CDK), first described in 1922, is a rare condition sometimes associated with other congenital malformations. There is a total anterior dislocation with recurvatum and upward displacement of the proximal tibia. This review covers our ten year experience at the hospital San Juan de Dios, in Caracas, Venezuela, a children's hospital with three orthopaedic services. We have seen 22 affected knees in 14 patients. Newborn patients were treated on traction until reduction was achieved, followed by serial plaster of Paris casts until, optimally, 90 degrees of flexion was gained. Surgical treatment was used if conservative treatment had failed after six months, or if the patient first presented after the age of 12 months. All our patients were eventually able to walk, three with the assistance of calipers. Some limitation of knee flexion was commonly seen. The best results were achieved when treatment was started early.

Abstract
Immunohistological analysis of bronchial biopsy specimens from nine patients with bronchiectasis and four control subjects was performed with a panel of monoclonal antibodies selected to show lymphocyte and macrophage subsets and signs of cellular activation. The cells taking part in the inflammatory response in the bronchial wall of patients with bronchiectasis were almost exclusively mononuclear cells, most of them T lymphocytes. B lymphocytes were observed in biopsy specimens from only two out of nine patients. CD8+ T cells outnumbered CD4+ cells in all patients in a ratio ranging from 2:1 to 10:1. Most T lymphocytes also strongly expressed CD7 antigen and a proportion of them expressed HLA-DR. Most of the lymphocytic infiltration occurred just beneath the basement membrane of the epithelium, though intraepithelial and submucosal infiltration was also seen. Non-lymphoid mononuclear cells expressing the phenotype of dendritic cells and macrophages were found dispersed throughout the infiltrate, most of them expressing HLA-DR. These observations support the hypothesis that cell mediated immunological reactions contribute to the inflammation associated with bronchiectasis.

Abstract
Uterine activity was measured by monitoring intrauterine pressure changes using ballon-tipped catheters placed in the lumen. An infusion rate of Na(2)EDTA of 35 mg/Kg/h gave a chelation rate equivalent to the rate of calcium mobilisation, and when infused at a level greater than this, resulted in a reduction in plasma calcium concentrations and a concomitant reduction in uterine activity. In three of the four sows infused intrapartum, there was complete cessation of uterine activity; however, plasma calcium concentrations of less than 6 mg 100 ml resulted in a reduction in uterine activity at this stage of parturition. The uterus of the sow post-partum appeared to be more sensitive to the effects of hypocalcaemia with reduced uterine activity when plasma calcium concentrations fell below 8.2 mg 100 ml and complete cessation of activity between 6 and 7 mg 100 ml . Although there was evidence of a delay in the expulsion of piglets in the hypocalcaemic sows, there was no evidence of an increased number of stillborn piglets compared with the two control sows.

Abstract
The effect of a distinctive first-trial cue on the degree of spontaneous recovery of moderately mentally retarded adults was investigated. The group given the cue showed more recovery of the operant response than did control groups for disinhibition on unextinguished discriminative stimulus. The group receiving the conventional procedure to produce spontaneous recovery, however, displayed significantly greater recovery than did any of the other groups. There was thus limited support for the hypothesis that cues associated with the first trial of a training session have greater significance for learners than do other cues.
