Efeito da ovariectomia em novilhas Nelore x Angus, Bos taurus indicus x Bos taurus taurus sobre os ganhos de peso

This study aimed to evaluate the weight gain in cross breed heifers Nelore X Angus, spayed and nonspayed, kept on pasture and confinement. The animals were allotted in two groups as follows: group I consisted of 30 nonspayed heifers with 18 months old. Group 2 was composed of 30 spayed heifers with 18 months old. The animals were allotted in pasture of Brachiaria decumbens and weighted at 39 and 75 days. Significant difference was observed between the average daily gain of the two groups - G1 and G2 (75(th) day), respectively (0.51 kg and 0.65 kg; P<0.0 1). The following day (761 day), all animals were allotted and kept on confinement during 144 days. Significant difference was observed between the average daily gain of the two groups - G I and G2 (1441 day), respectively (0.73 kg and 0.58 kg; P<0.0 1). The results of this experiment show that spayed heifers presented a higher daily gain on pasture.

Análise histomorfométrica da influência do Alendronato sódico no processo de reparo ósseo em tíbia de ratas submetidas a ovariectomia

The sodium alendronate (AS), considered as inhibitor in the osteoclasts- mediated bone resorption, promotes final effect of inhibition of resorption and increases bone mass. The objective of this research was to assess, by histomorphometry, the effect of sodium alendronate in repair bone of ovariectomized rats, in which there was performed a bone defect in the right tibia. The treated rats received a subcutaneous injection of sodic alendronate once a week, at 0.7 mg / kg, diluted with saline solution; the controls received the same volume of saline solution. In the periods of 16, 30 and 44 days after the first dose of AS, the animals were sacrificed, the right tibia was removed and processed for histomorphometric analysis. Four non-serial fields were used for the density volume quantification utilizing an integrative eyepiece with 25 points, totalizing 100 points per animal. Based on the results, the present study concludes that the ovariectomy induced osteoporosis and that the AS stimulated the bone formation. In addition, the ovariectomy decreased the estrogen levels. However, this procedure did not significantly influence the action of sodic alendronate.

Manifestação incomum de paralisia de membros pélvicos em felino com hidronefrose decorrente de ovariectomia - Relato de caso

This study describes the occurrence of iatrogenic hydronephrosis in left kidney with compression of the abdominal aorta in persian cat and paralysis of hind limbs. The animal had slight dehydration, pale mucous membranes, cold extremities and cyanotic, absence of bilateral femoral artery pulse, and absence of superficial and deep pain, and presence of a mass of firm consistency with six centimeters in diameter, on abdominal palpation. Performed exploratory celiotomy, there was increased left kidney compressing the abdominal aorta and dilation of the cranial left ureter attached to the uterine horn by means of ligation with nonabsorbable. After nephrectomy, it was observed the restoration of local circulation. The animal died after eight hours.
