奶牛产后胎衣不下和子宫内膜炎是影响奶牛繁殖的重要因素。许多研究证明,患有这种疾病的奶牛,通常表现为发情延迟、受胎率低,从而降低了奶牛繁殖能力。对产后胎衣不下,阴道排泄物异常,子宫恢复异常的奶牛积极进行治疗是提高奶牛繁殖能力的有效手段。通常在奶牛产后直接向子宫投药,作用于子宫腔和子宫内膜的药物浓度比其它途径给药方式更高,维持时间更长。因此,实际工作中畜牧兽医人员常常采用子宫灌注法进行治疗。 相似文献

On the basis of a digital analysis of radiograms it was checked if, and to what extent, the extended loading of one of the sides of the body of racehorses leads to differences in the microstructure of the spongy bone of the bilateral pastern bones of the thoracic limbs. The research material consisted of radiograms of the pastern bones of the right and left thoracic limbs of racehorses. On the basis of computer image radiological analysis with the use of the "Trabecula,, programme, a quantative evaluation of the structure of the spongy bone of the pastern bones was conducted. It was noted that the differences between the right and the left pastern bones, despite extensive loading of the left thoracic limb, were not statistically significant as far as all studied parameters of the trabecula structure of the spongy bone were concerned. 相似文献

Uterine motility may have significance for the transportation of spermatozoa and the elimination of the ejaculate and inflammatory products after mares have been covered. The effect of some of the component stimuli of coitus on uterine contractions was investigated by using M-mode ultrasound. The number, amplitude and duration of the uterine contractions of each uterine horn and of the uterine body were measured in oestrous mares for four minutes before and four minutes after teasing by a stallion, mechanical stimulation of the vagina and cervix, the intrauterine infusion of 80 ml of sterile saline, the intrauterine infusion of 10 ml of sterile saline, the intrauterine infusion of 150 ml of sterile saline, and the transcervical passage of a uterine catheter. Teasing by a stallion did not affect the total number, mean amplitude or mean duration of the uterine contractions. Mechanical stimulation of the vagina and cervix increased the total number of uterine contractions, but did not affect the amplitude or duration of the contractions. The intrauterine infusion of 80 ml of sterile saline resulted in an increase in the total number of contractions and a significant increase in the mean amplitude and the mean duration of the contractions in the uterine horns but not the uterine body. The intrauterine infusion of 10 ml of sterile saline caused a significant decrease in the number of uterine contractions in the uterine horns, but had no effect on the contractions of the uterine body. The infusion of 150 ml of sterile saline reduced the number of contractions in the uterine horns but not the uterine body, and did not affect the mean amplitude and mean duration of the contractions. The transcervical insertion of a catheter reduced the number of contractions in the uterine horns, but did not affect the amplitude or duration of the uterine contractions. 相似文献

Bilateral orchidectomy caused a marked decrease in the concentration of testosterone in the bood plasma of boars already in the early post-castration stage of three hours after the operation. In the period from 3 to 207 days after castration, the pre-operation levels of plasma testosterone decrease by 84.4%, on an average. Adreno-cortical compensation of the concentration of the hormone did not occur in the post-castration period. The conclusion is that the levels of testosterone in the blood of boars are mostly of testicular origin and can be considered as the main criterion of the incretion function of the testes. The discussion concerns the practical importance of the determination of testosterone levels in the blood of boars for clinical evaluation of the hormonal function of the testes and for diagnostics of incretion hypogonodism. 相似文献

Eight healthy dogs of mixed breeds with short hair coats were used in this study. The skin and the hair of a small area on the left side of the saddle region were dyed 80 times once every day with a permanent hair dye, Clairol Hair Dye Flaxen Blonde. The dyed regions were red and dry toward the last two weeks of the experiment. None of the dogs had abnormal hair shedding. Four of the dogs were restless, and their epidermis were parakeratotic and hyperkeratotic.
The cuticular cells of the hair shafts of two dogs upon examination showed deep fractures at the lower part of the hair shaft. The fractures extended through the whole thickness of the cuticular cells leading to splitting of the hair shaft. Secondary hairs showed excessive peeling of their cuticle cells causing distortion and deterioration of the cortex of the hair. Cuticular cells of large numbers of hairs lost their apical parts and some of them were deformed due to partial dissolution attributed to the intensive use of the hair dye. The intensive usage of the hair dye on the compound type of hair coat of the dog caused damage to the hair shafts and to the skin in the form of irritation, dryness and parakeratosis of the epidermis. Also, some of the dogs became restless and hyperactive during the later part of the experiment. 相似文献

A 5-month-old castrated male mixed-breed dog was evaluated because of lameness of the right forelimb. Physical examination revealed pain on manipulation of the right elbow joint, and radiography revealed premature closure of the distal physis of the radius with subluxation of the right elbow joint. Corrective osteotomy of the radius was performed to increase the length of the radius and establish congruity of the elbow joint. Cancellous bone was obtained from the proximal portion of the humerus and used as a graft at the osteotomy site. The dog did well after surgery. Four months after surgery, the dog again was lame on the right forelimb. Physical examination revealed instability of the right shoulder, and manipulation of that area elicited signs of pain. Radiography revealed caudomedial subluxation of the right shoulder as well as deformity of the humeral head and hypoplasia of the greater tubercle. It was presumed that these changes were associated with collection of the cancellous bone graft during the initial surgery, which resulted in premature closure of the proximal physis of the humerus. To our knowledge, this is the first report of premature closure of the proximal physis of the humerus as a result of procurement of a bone graft. 相似文献

The maximum length and depth of the longitudinal section, and the maximum width and depth of the transverse section of the gall bladders of 32 dog cadavers were measured ultrasonographically; the contents of the gall bladder were then aspirated and its actual volume measured. The volume of the gall bladder was estimated from the ultrasonographic measurements by using formulae suggested for assessment of the volumes of the urinary bladder in human beings and the gall bladder of dogs, and these formulae were compared with a formula derived from the measurements made in this study. In 21 of the dogs, the measurements were repeated twice so that their reproducibility could be evaluated. All the formulae gave good estimations of the volume of the dogs' gall bladders, but the formula for the human urinary bladder volume was better than the other two. The actual volume of the gall bladder was related to the dogs' bodyweight. There were no significant differences between the repeated measurements of the maximum length and depth of the longitudinal section or the width of the transverse section of the gall bladder, but there were significant variations in the depth of the transverse section. 相似文献
