SINAIS CLÍNICOS DO LINFOMA CANINO
O linfoma é uma neoplasia com origem nos tecidos linfóides sólidos e bastante freqüentes
em cães. O objetivo deste trabalho foi descrever os sinais clínicos dos cães com diagnóstico linfoma
citológico e/ou histopatológico, atendidos no Hospital Veterinário da FMVZ de Botucatu - SP. Os dados
obtidos foram retirados dos prontuários de 54 cães com linfoma, atendidos num período de 28 meses
(fevereiro de 1997 a maio de 1999) no referido hospital. A manifestação clínica mais comum foi
linfoadenopatia generalizada em 87,04% dos cães. Os sinais clínicos também incluíram apatia (68,52%),
perda de peso (68,52%) e hiporexia (42,59%). Os resultados permitem concluir que os sinais clínicos
do linfoma canino são variados e inespecíficos.
Clinical signs of the canine lymphoma
Abstract
Canine lymphoma, one of the most frequently detected tumors in dogs, is a neoplasia
originating in lymphoid tissues. Over a period of 28 months (February 1997 - May 1999), 54 dogs with
diagnosis of lymphoma were evaluated at the Veterinary Hospital of Botucatu, SP. The objective was to
describe the clinical findings of dogs with lymphomas. Lymphadenopathy was the clinical finding of
highest incidence (87.04%) among the animals studied. Apathy (68.52%), weight loss (68.52%) and
hyporexia (42.59%) were the most frequent clinical findings. We conclude that the clinical findings vary
as a function of anatomical classification and clinical staging of the tumor
LINFOMA CANINO ACHADOS CLÍNICO-PATOLÓGICOS
O linfoma é uma neoplasia com origem nos tecidos hematopoiéticos sólidos e é um dos
tumores mais freqüentes em cães. Os resultados dos exames laboratoriais obtidos foram retirados
dos prontuários de 54 cães com diagnóstico de linfoma, atendidos num período de 28 meses (fevereiro
de 1997 a maio de 1999) no Hospital - Botucatu SP. O objetivo foi descrever as alterações
hematológicas, do exame de urina e do perfil bioquímico sérico nestes cães. As alterações
hematológicas mais freqüentes foram anemia e leucocitose, que ocorreram em 44,44% dos casos.
As alterações do exame de urina e do perfil bioquímico sérico foram infreqüentes. O aumento sérico
da bilirrubina e das enzimas hepáticas sugerem invasão do fígado por células neoplásicas. A
hipercalcemia e hiperglobulinemia foram as síndromes paraneoplásicas suspeitas neste estudo.
Conclui-se que os achados bioquímicos e hematológicos do linfoma canino são inespecíficos e
variados.
Clinical pathologic alterations - canine lymphoma
Abstract
Canine lymphoma, one of the frequently detected tumors in dogs, is a neoplasia
originating in lymphoid tissues. Over a period of 28 months (February 1997 - May 1999) the hematologic,
urinalysis and biochemical alterations of 54 dogs with a clinical diagnosis of lymphoma were evaluated
at the Veterinary Hospital - Botucatu, SP. Anemia and leukocytosis were the most frequent hematological
changes occurring in 44.44% of the cases. Changes in the routine urinalysis or serum clinical chemistry
were infrequent. Increased serum levels of bilirubin and liver enzymes suggest invasion of the liver by
neoplastic cells. Hypercalcemia and hypergammaglobulinemia were suspected as paraneoplasic
syndromes in this study. We conclude that the biochemical and hematological findings of canine
lymphoma are nonspecific and variable
Clinical changes in cats submitted to experimental hyperthyroidism
A relação do hipertireoidismo experimental com parâmetros clínicos foi avaliada em
gatos machos e fêmeas, intactos e mantidos em estado hipertireóideo por um período de 42 dias.
Os parâmetros estudados foram consumo diário de água e ração, débito urinário, o volume fecal,
peso corporal, temperatura corporal, coloração de membranas mucosas, palpação de linfonodos
superficiais, palpação da glândula tireóide, pulso femoral, auscultação cardíaca e respiratória,
freqüência cardíaca e respiratória e palpação abdominal. Correlacionou-se as variáveis com os
níveis de T3 total, T4 livre e total. O excesso dos hormônios tireoidianos acompanhou aumento da
freqüência cardíaca, polifagia, polidipsia, perda de peso e aumento do volume fecal nos gatos
estudados.The interrelation between experimental hyperthyroidism andclinical changes was
studied in adult intact cats kept under hyperthyroidic state for 42 days. Clinical aspects evaluated
were dairy food and water intake, urine output and fecal volume, body weight, temperature,
mucous membranes colour, palpable lymphnodes, thyroid gland palpation, abdominal palpation,
and cardiac and respiratory frequencies. These characteristics were correlated with free and
total T4 and total T3 serum concentrations. Excessive circulant thyroid hormone levels resulted
in increased cardiac frequency, polyuria, polidipsia, weight loss and increased fecal volume in
the studied cats
On the linear forms of the Schrodinger equation
Generalizing the linearisation procedure used by Dirac and later by
L\'evy-Leblond, we derive the first-order non-relativistic wave equations for
particles of spin 1 and spin 3/2 starting from the Schrodinger equation

Thermostatistics of deformed bosons and fermions
Based on the q-deformed oscillator algebra, we study the behavior of the mean
occupation number and its analogies with intermediate statistics and we obtain
an expression in terms of an infinite continued fraction, thus clarifying
successive approximations. In this framework, we study the thermostatistics of
q-deformed bosons and fermions and show that thermodynamics can be built on the
formalism of q-calculus. The entire structure of thermodynamics is preserved if
ordinary derivatives are replaced by the use of an appropriate Jackson
derivative and q-integral. Moreover, we derive the most important thermodynamic
functions and we study the q-boson and q-fermion ideal gas in the thermodynamic
limit.Comment: 14 pages, 2 figure
