Radiographic Estimation of Pregnancy in Goats     

M. Saleh  A.S. Ahmed  A.H. Nono  H.M. Eissa 《Reproduction in domestic animals》1988,23(1):38-42

Contents: The onset and progression of goat fetal skeletal radio opacity were studied to identify the stage of pregnancy and the number of fetuses present. Lateral radiographs using 75 KVP, 200 Ma, 0.25 s and 100 FFD was found to be good values for detection of pregnancy in goats. Lengths taken for skull, femur and vertebral column of the fetus were used as a parameter for determination of the stage of pregnancy. Counting the number of fetal skulls were used for estimating the number of fetuses present. Accurate radiological diagnosis of pregnancy in goat was possible after 10 weeks of gestation .
Inhalt: Radiographische Bestimmung der Trächtigkeit bei der Ziege
Der Beginn und die Weiterentwicktung fötater Skelettbildung wurde radiologisch bestimmt, um das Stadium der Trächtigkeit und die Zahl der Föten zu ermitteln. Laterale Röntgenbilder wurden mit 75 KVP, 200 Ma., 0,25 Sek. und 100 FFD ermittelt, wobei sich diese Einstellung als günstig für die Trächtigkeitserkennung bei Ziegen erwies. Die Ermittlung der Schädellänge, des Femurs und des Rückenmarks beim Fötus wurden als Parameter für die Bestimmung des Trächtigkeitsstadiums benutzt. Die Zahl der Fötalschädel ergab die Zahl der Föten. Genaue radiologische Diagnose der Trächtigkeit bei Ziegen war ab etwa 10 Wochen der Trächtigkeit möglich .  相似文献   

Virulence, cytotoxic and inflammatory activities of Vibrio anguillarum and Aeromonas salmonicida isolated from cultivated salmonid fish in Sweden     

Karel Krovacek  Ahmed Faris  Laila Eriksson  Eva Jansson  Olle Ljungberg  Ingmar Mnsson 《Acta veterinaria Scandinavica》1987,28(1):47-54

Extracellular products in culture filtrates of Aeromonas salmonicida subsp. achromogenes and Vibrio anguillarum isolated from infected fish have been shown to possess skin inflammatory factor. The extracellular products from Vibrio anguillarum were cytotoxic in HeLa and CHO cells. In addition to the skin lesions, the culture filtrates of V. anguillarum caused necrotic reaction on the rabbit skin. Five of 6 strains of V. anguillarum were lethal to mice after intraperitoneal administration of 3×10⁷ CFU. Only 1 strain of 5 A. salmonicida subsp. achromogenes produced extracellular products which elicited cytotoxic effects in the CHO cells. None of the A. salmonicida subsp. achromogenes strains were lethal to mice. The cytotoxins were inactivated when heated at 65°C for 30 min. The results indicate that the thermolabile exotoxins are non-enterotoxic since they failed to stimulate fluid accumulation in the rabbit ileal loop and did not cause elongation of the CHO cells. The rounding off of CHO cells, as well as of HeLa cells indicate that the exotoxins may play an important role in fish diseases.  相似文献

Arteria maxillaris of the donkey (Equus asinus)     

M A Ahmed  H Anis  M S Moustafa 《Anatomia, histologia, embryologia》1984,13(4):333-340

Gross anatomical examination of the organization of the maxillary artery was carried out in 10 formalin embalmed, latex injected adult donkeys. The results indicate that although there are variations from other domestic animals, the distribution of this artery in the donkey is similar to that of the horse.  相似文献

Effects of Jatropha curcas on calves.     

O M Ahmed  S E Adam 《Veterinary pathology》1979,16(4):476-482

Jatropha curcas seed was fed to six calves at doses of 2.5, 1 and 0.25 g/kg once and to two other calves at 0.025 g/kg up to 14 days. The onset of toxic manifestations in the six calves was rapid and death occurred within 19 hours of administration. The two calves that received daily the lowest dose of J. curcas showed signs of poisoning and died within 10 to 14 days. The clinical signs of diarrhoea, dyspnoea, dehydration and loss of condition were well correlated with the pathological findings. There was an increase in aspartate aminotransferase, ammonia and potassium and a decrease in total protein and calcium in the serum of jatropha-poisoned calves.  相似文献

Abomasal cannulation in the milk-fed calf using a 7 mm polyurethane tube     

Ahmed AF  Constable PD  McCallister MM  Misk NA 《Journal of veterinary medicine. A, Physiology, pathology, clinical medicine》2005,52(1):39-42

The main objective of this study was to develop a simple and effective surgical technique for abomasal cannulation in neonatal calves. General anaesthesia was induced in 12, 3-day-old male dairy calves and a polyurethane cannula surgically implanted in the abomasal body (n = 12) and pyloric antrum (n = 6) through a right paracostal incision. Fifteen cannulae remained in situ from day 3 to 34 of life (mean: 29 days), and three cannulae were extruded 13-14 days after placement. Calves were clinically healthy and gained weight during the study. Cannulae were well tolerated by the calves and abomasal contents did not leak from the cannula sites. Necropsy examination revealed firm adhesions between the abomasum and parietal peritoneum at the cannula sites with no evidence of leakage or peritonitis. We conclude that surgical placement of polyurethane tubes designed for percutaneous endoscopic gastrostomy provided a useful method for cannulation of the abomasum of neonatal calves. The cannulation technique can be used for experimental studies, as well as for nutritional and fluid support of sick calves that cannot be managed by oral treatment.  相似文献
