Periodicity in tree rings from the corn belt     

Meko DM  Stockton CW  Blasing TJ 《Science (New York, N.Y.)》1985,229(4711):381-384

Previous tree-ring studies indicated that the total area affected by drought in the western United States has rhythmically expanded and contracted over the past 300 years, with a period near the 18.6-year lunar nodal and 22-year double-sunspot cycles. Recently collected tree-ring data from the U.S. Corn Belt for the years 1680 to 1980 were examined for evidence of either of these cycles on a regional scale. Spectral analysis indicated no periodicity in the eastern part of the Corn Belt, but a significant 18.33-year period in the western part. The period length changed from 17.60 to 20.95 years between the first 150 years and the last 151. High-resolution frequency analysis showed that the structure of the 18.33-year spectral peak was complex, with contributions from several frequencies near both the lunar nodal and double-sunspot periods. A t-test of difference of means in reconstructed annual precipitation weakly corroborated a previous finding of an association between drought area and the phase of the double-sunspot cycle. Both the high-resolution frequency analysis and the t-test results indicate that the periodic component of drought near 20 years is too weak and irregular to be of use in drought forecasting for the Corn Belt.  相似文献   

Plasma cell sarcoma in a cat     

Mitcham SA  McGillivray SR  Haines DM 《The Canadian veterinary journal. La revue veterinaire canadienne》1985,26(3):98-100

Lytic lesions occurring in conjunction with plasma cell sarcoma (multiple myeloma) have rarely been reported in cats.

A plasma cell sarcoma was diagnosed in a 13 year old castrated male Siamese cat with hind limb paresis resulting from osteolysis of the second lumbar vertebra. Serum electrophoresis showed a monoclonal gammopathy. A uniform population of plasma cells was found in and around the second lumbar vertebra and in the bone marrow of the femora, humeri, pelvis and the fifth lumbar vertebra. The neoplastic cells were identified as IgA and kappa chain specific by direct immunofluorescence.

Observations on an outbreak of foot abscess in sheep     

West DM 《New Zealand veterinary journal》1983,31(5):71-74

An outbreak of ovine interdigital dermatitis and foot abscess in which approximately a third of 300 Perendale ram hoggets had acute lameness was investigated. Both foot infections occurred simultaneously in the flock, and ovine interdigital dermatitis preceded the occurrence of foot abscess in seven instances. It was suggested that the behaviour pattern and sexual activity of the young rams predisposed them to ovine interdigital dermatitis and foot abscess. Although no controlled trials were conducted, the lame sheep responded well following the combined therapeutic measures of dry surroundings, formalin footbathing and selected antibiotic therapy.  相似文献

Observations on three outbreaks of Leptospira interrogans serovar pomona infection in lambs     

Vermunt JJ  West DM  Cooke MM  Alley MR  Collins-Emerson J 《New Zealand veterinary journal》1994,42(4):133-136

Sickness and deaths associated with leptospirosis were reported in three lamb flocks in the Manawatu region. The clinical, pathological and serological features of Leptospiru interrogans serovar pomona infection are described. The mucous membranes of affected animals were pale and jaundiced. Haemoglobinuria, haemoglobinaemia and centrilobular hepatocellular necrosis were also consistent findings. All clinically sick lambs had very high titres in the microscopic agglutination test for L. pomona. Circumstantial evidence of pigs being the source of infection was found in one of the three cases.  相似文献

Suspected photosensitisation in lambs grazing birdsfoot trefoil (Lotus corniculatus)     

Stafford KJ  West DM  Alley MR  Waghorn GC 《New Zealand veterinary journal》1995,43(3):114-117

Suspected photosensitisation occurred in three groups of lambs grazing birdsfoot trefoil (Lotus corniculatus c.v. Grasslands Goldie). In one group, sucking lambs aged about 10 weeks, grazing birdsfoot trefoil, developed skin lesions while lambs of a similar age and from the same flock grazing lucerne (Medicago sativa) or a mixed sward of both species showed no signs of photosensitisation. Affected lambs had lesions on their backs and ears. In a few animals the tips of the ears were shortened by 2-3 cm. In the affected lambs, serum liver enzymes (gamma-glutamyltransferase, glutamate dehydrogenase), bilirubin and serum Vitamin B12 levels were within the normal range. At necropsy, no significant pathological changes were detected in the liver and histological changes in the skin were consistent with primary photosensitisation. In the second group, three of 80 weaned lambs grazing the same birdsfoot trefoil at a restricted intake were affected in the same manner as the first group. In the third group, 15 animals from 28 sets of sucking twin lambs were also affected. In only two sets of twins were both lambs affected. None of the ewes grazing with the lambs in the first or third groups showed any clinical signs of photosensitisation.  相似文献
