北疆冬景

冰天雪地的北大荒,让人听了都心冷胆寒,望而却步。可长年生活在这里的北大荒人天天和冰雪打交道,却'打'出了交情,难舍难分,赖以生存了。若离开了冰雪,他们的生活就失去了多趣和神奇,失去了诗情画意。用北大荒人的话说:'若没有冰雪,就像失去阳光和空气一样,没法活了!'何以这样说?走进他们的生活,就能窥豹一斑了。

ULTRASONOGRAPHIC FINDINGS IN CHOLECYSTOKININ-INDUCED PANCREATITIS IN DOGS

Pancreatitis can be induced in dogs by intravenous infusion of supraphysiologic doses of synthetic cholecystokinin octapeptide (CCK-8). Eight anesthetized female beagles were given either CCK-8 or saline in a randomized, blinded fashion and had abdominal ultrasonography to study the development of pancreatic lesions. Pancreatic lesions were apparent 2 hours after the start of CCK-8 infusion and included swelling, interlobular and subcapsular fluid accumulation and patchy hypoechogenicity of the gland parenchyma. CCK-8 had a variable effect on gallbladder emptying. No signs of biliary obstruction or duodenal lesions were identified. Dogs given CCK-8 had severe edematous pancreatitis at necropsy six hours after the start of the infusion. Compared to the oleic acid model of pancreatitis, CCK-8 infusion induces a rapid onset of pancreatitis and an ultrasonographic appearance that reflects diffuse edema of the gland. The short time-scale of the experiment may account for the relative absence of secondary lesions affecting the biliary tract or duodenum compared to the naturally-occurring disease.     

PREGNANCY IN SLAUGHTERED COWS IN NORTH-EASTERN AUSTRALIA

A total of 7495 postpuberal beef cows from herds in north Queensland and the Northern Territory were examined at abattoirs to define the extent of wastage due to the slaughter of pregnant cows. On the basis of examination of teeth most cows (57%) were considered mature (approximately 3.5 to 7 years) at slaughter; 14% were young (9 months to 3.5 years) and 29% were old (over 7 years). In herds where pregnancy diagnosis by rectal examination had not been used at time of culling, 71.6% of slaughtered cows were pregnant and 42% of these cows were in the second trimester. This high pregnancy rate was considered an important source of herd wastage. Pregnancy rate varied little with season, but the highest percentages of cows pregnant in the first and third trimesters were recorded in autumn and spring, respectively. Most cows found non-pregnant had active ovaries at time of slaughter. Anoestrus was observed to be most common in winter and in old cows. Lactational status was not recorded. Mean cold carcase weight of 4229 cows was 161 +/- 40 kg. Maximum carcase weight was observed in cows slaughtered at 4 to 6 years of age; old cows had the lowest carcase weight (147 +/- 31 kg) of the age groups considered. Highest (170 +/- 43 kg) and lowest (135 +/- 41 kg) carcase weights in relation to pregnancy or ovarian status were observed in non-pregnant/ovary-active and non-pregnant/anoestrus cows respectively. Carcase weight of cows in the third trimester (165 +/- 35 kg) was greater than in the second (161 +/- 35 kg) or first (157 +/- 36 kg) trimesters; difference between the first and third trimesters was significant (P less than 0.01).
