ABSTRACT
La miomectomía histeroscópica es una técnica que produce muy buenos resultados en el tratamiento de los miomas submucosos controlando las hemorragias uterinas disfuncionales. Además produce menores costes y una recuperación más rápida que las técnicas convencionales. Es importante para asegurar la efectividad de esta técnica una selección adecuada de las pacientes y una correcta clasificación de los miomas. Se deben tomar precauciones para minimizar los riesgos de la ténica que en ocasiones pueden ser muy graves. A continuación realizamos una revisión de las indicaciones, contraindicaciones, condiciones y diferentes técnicas de la miomectomía histeroscópica
The histeroscopic myomectomy is a good and effective procedure for the treatment of submucous myomas controlling abnormal uterine bleeding. It also offers economic savings and a quicker recovery. It is important for the effectiveness of the procedure to make a correct patient selection and to use standard methods to clasificate myomas. Precautions should be taken to minimize complications because they can be life threatening. In this article we make a review of the indications, contraindications, conditions and different techniques of the hysteroscopic myomectomy

La histeroscopia es una técnica con una tasa de complicaciones baja, que la convierten en un método diagnóstico y terapéutico seguro y con una alta tolerabilidad. A pesar de ello, debemos conocer los riesgos que comporta, comprender su naturaleza y analizar estrategias para evitar su aparición
Hysteroscopy is a technique with a low incidence of complications. In fact, it is a safe diagnostic and surgical procedure. Despite of this, we must have knowledge of them to be able to increase the quality management of operative hysteroscopy

Las indicaciones para los procedimientos histeroscópicos en ginecología son varias, sencillas y claras. Se considera una técnica fundamental hoy en día, no sólo para visualizar el canal endocervical y la cavidad uterina, sino porque también permite el tratamiento de diferentes patologías, ya sea de manera ambulatoria o en quirófano. En cuanto a sus contraindicaciones, su número es limitado
The indications for the hysteroscopy procedures in gynaecology are different, simple and clear. It is considered to be a fundamental technique nowadays, not only to visualize the endocervical channel and the uterine cavity, but because also it allows the treatment of different pathologics, in outpatient way or in surgical suite

A study of age-related changes in carcass traits and meat quality characteristics of Longissimus dorsi (LD) and Biceps femoris (BF) of free-ranged Iberian pigs was carried out to check whether the slaughter age used in the traditional management system of Iberian pigs is adequate. There was a great increase in live and carcass weight during fattening, principally due to an increase in fat deposition, as could be deduced from the percentage of dissectible fat and the backfat thickness. However, intramuscular fat in LD and BF showed only slight changes during the fattening. Myoglobin content tended to increase throughout lifetime in both muscles, whereas water-holding capacity decreased in intermediate ages and showed the highest values in the oldest animals. Total collagen content did not vary during lifetime; on the other hand, insoluble collagen increased from 7 to 77% of total collagen. It can be concluded that the traditional management system of Iberian pigs can be improved by fattening the pigs at a younger age, without negative consequences on the meat quality.
ABSTRACT
Observations on craniofacial axes and angles were made on fifty dogs belonging to five breeds, by means of radiological techniques (lateral radiographs) and biostatistical methods. The craniofacial angles were found to be 25-26 degrees (greyhound), 19-20 degrees (pointer), 20-21 degrees (German shepherd), 13-14 degrees (boxer) and 9-10 degrees (Pekinese). Shortening of the head in brachycephalic dogs implies a more perpendicular development of the cranium relative to the facial axis. The possible application of these data in the determination of morphological types in many fields is discussed.

One hundred forty four ovine embryos and feti were used in an investigation to determine mathematical models describing the histomorphometric growth of tissues and compartments of the ruminant stomach. The results indicate that during prenatal life the diameter of the gastric chambers increase more slowly than the length. The tissue layers of the gastric walls, particularly the muscular tunic of all compartments demonstrated a uniform tendency toward more rapid development than the compartment walls proper.

Histomorphometric analyses were carried out on 64 embryos and fetuses and on 20 sheep (early postnatal to adult age). Histodifferentiation of the abomasum took place at 33 days of fetal life, with the appearance of abomasal villi at 53 days. By 64 fetal days, the epithelium had changed from pseudostratified to simple mucous cylindrical. Acidic glycoproteins appeared at 46 fetal days. Neutral glycoproteins did not appear until later stages of development, near birth. We believe that the configuration of a simple epithelium with acidic secretion is enhanced at birth by the secretion of neutral glycoproteins which act as a buffer against acidic substances, and particularly against the abomasal acidity during lactation. Growth curves and formulae were set out for each tissue layer.

A radiological investigation of the sternum of the sheep demonstrated distinct growth phases. Forty Merino sheep of mixed breeds were distributed into 4 age groups of 0, 45, 105 and 270 days. Each animal was radiographed in sternal and lateral recumbency. Measurements were made from the radiographs. The sternebrae are rectangular in newborn and become concave in adult. The curvature of the sternum is 16 to 17 degrees at day 0 and 27-28 degrees at day 270. The nucleus of ossification was seen in all sternebrae at 45 days of age, they were present only in the most caudal sternebrae at 105 days.

A study was made of 160 long bones taken from 40 native Merino sheep of both sexes. These animals, which represented uniform growth (mean growth-curve values), were divided into four groups which were slaughtered consecutively at 0, 45, 105 and 270 days old (0, 6.4, 15 and 38.5 weeks, respectively). The following bones were studied; humerus, femur, tibia and os coxae. Thin lamellae taken from the metaphyses of the bones obtained were fixed, decalcified and stained with hematoxylin-eosin to assess the development of the various components of growing bony tissue. The bones studied followed the same maturation pattern; the os coxae proved to be the best histological indicator in differentiating the age of the animals studied.

The volumetry of the cranial cavity of 30 galgo hounds (15 males and 15 females) has been studied by computerized axial scanning tomography and biostatistical methods. The serial tomodensitometric sections of heads were 5 mm thick and 5 mm distant, taken in sagittal and transverse planes. Results demonstrate a sexual differentiation, with a security of 99.99%. The discussion turns to zootechnical and osteoarcheological applications.

In order to carry out this study, 62 embryos and fetuses of Friesian cows were used, and every stomach was dissected and subjected to the usual laboratory procedures. After obtaining each preparation all the histological and metrical changes that took place in the wall of the viscus during its development are described. The compartments are histologically differentiated into three stages: in the first one there is no compartment differentiation: in the second one, the rumino-reticulum, omasum and abomasum have differentiated; and in the third one every compartment is differentiated. In group 16, (78 days of gestation), a decrease in thickness of the muscular layer of all compartments, parallel to the histological differentiation has been observed.
