Valores bioquímicos séricos de tilapia del Nilo (Oreochromis niloticus) en cultivo intensivo

The aim of the study was to evaluate the serum biochemical parameters of the Nile tilapia (Oreochromis niloticus), Thai Chitralada lineage, raised under an intensive pisciculture system and captured by the cast net technique. Blood samples from 40 individuals were obtained by caudal venopuncture. Mean body weight was 453 ± 52 g. The serum biochemical parameters evaluated were total protein, albumin, globulins, acid uric, creatinine, urea, calcium, inorganic phosphorus, Ca/P ratio, alkaline phosphatase, and magnesium. In general, the data showed similar parameters in comparison to those established for scale fish, exception of the acid uric.

Uso de marcadores parasitológicos e imunológicos na seleção de ovelhas resistentes às parasitoses gastrintestinais

This work was conducted to verity the possibility to identify adult sheep that are resistant to parasites by using a parasitological marker (direct), immunological markers (indirect) or by the association of both types of markers. Twenty ewes were sampled monthly for blood and faeces, from July of 1998 to June of 1999. Faecal egg counts (FEC) was chosen as parasitological marker. The number of peripheral eosinophils, IgE and IgG anti-Haemonchus contortus were used as immunological markers. Sheep could be classified as resistant or susceptible by FEC. Both peripheral eosinophils and specific IgE data could be joined to FEC in order to identify resistant or susceptible animals. The number of peripheral eosinophils was the only immunological maker that was able to classify high and low FEC ewes in two different groups.

Parâmetros bioquímicos de avaliação da função renal e hepática de equinos com cólica submetidos a laparotomia, sobreviventes ou não

We examined 46 adult horses - six healthy, as control, (group 1) and 40 horses with colic submitted to treatment by laparotomy. Twenty animals had no postoperative complication (group 2), and twenty died or were euthanized from seven to ten days after the surgery (group 3). There was an increase in serum urea and creatinine concentration and AST, FA and GGT activity of animals from group 1 and group 2, indicative of renal and hepatic injury. The changes were associated with dehydration and endotoxins. Depending on the severity of the colic, animals may develop kidney and liver failure.

Indicadores bioquímicos séricos e do líquido peritoneal de equinos submetidos à obstrução intestinal

Twenty-four horses were distributed into four different groups, instrumented control (GI), duodenum obstruction (GII), ileum obstruction (GIII) and large colon obstruction (GIV). Serum and peritoneal fluid analysis of aspartate aminotransferase, creatine kinase, lactate dehydrogenase, alkaline phosphatase, inorganic phosphorus and lactate were measured. Samples were collected one hour before the surgical procedure (T0); 3 hours after the obstruction (T3ob), 1, 3, 12, 24, 120 and 168 hours after the beginning of reperfusion/deobstruction. Duodenal (GII) and ileum (GIII) obstructions changed serum and peritoneal fluid biochemical analysis. However, only lactate, lactate dehydrogenase, creatine kinase and inorganic phosphorus concentrations were abnormal in peritoneal fluid three hours after the obstruction. The biochemical analysis of peritoneal fluid allowed a faster diagnostic of intestinal alterations than the serum analysis; hence it should be prioritized when pre-operatory colic assessment is carried out.

Glicemia, proteinograma e perfil de alguns componentes bioquímicos séricos de cabritos da raça bôer

The newborn goat kids suffer several adjustments to life outside the uterus that affect different body functions that they need to produce heat, muscle activity and start searching for food. All these events lead to changes in several blood constituents such as proteins and serum biochemical parameters. Other studies have shown these variations, but not extend beyond the neonatal period to phase in young animals. The aim was to test the hypothesis that there is variation of the protein profile, and biochemical components of blood glucose in goat kids from birth to 75 days of life in terms of adaptation to extra uterine life. To achieve these objectives have been collected blood samples from 25 goats born by normal delivery, regardless of their sex. The variables serum total protein (TP), albumin, α-globulin, β-globulin, γ-globulin, which includes the immunoglobulin G (IgG), aspartate (AST), alkaline phosphatase (ALP), gamma-glutamyltransferase (GGT), creatinine and urea, and glucose were determined at times zero (immediately after birth), two, seven, 15, 30 and 75 days old. We observed significant differences in all variables between times, but only the creatinine concentration was higher than those of other moments in time zero and two days old, probably due to immaturity of renal function in newborn animals. The blood constituents of the kids had variations in the study period, related to physiological and nutritional causes.

Glicemia, proteinograma e perfil de alguns componentes bioquímicos séricos de cabras da raça bôer no pós-parto

The objective was to test the hypothesis that there is variation of some protein components, biochemical and glucose from the blood of goats in the postpartum period. ElevenBoer goats were used to evaluate the serum following variables: total protein (TP), albumin, α-globulin, β-globulin, γ-globulin, immunoglobulin G (IgG), aspartate (AST), alkaline phosphatase (ALP), gamma-glutamyltransferase (GGT), creatinine, urea and glucose. These components were determined in moments zero (immediately after delivery), two, seven, 15, 30 and 75 days postpartum. The β-globulin, IgG, creatinine and urea from the goats did not show significant variations, the blood glucose at time zero was greater than the baseline values due to physiological stimulation of glycogenesis determined by the increase of cortisol in delivery. The blood constituents of goats showed variations in the period to 75 days postpartum as a result physiological causes related to delivery and postpartum.

Aspectos fisiológicos e bioquímicos de cultivares de soja submetidos a déficit hídrico induzido por peg 6000

In soybean culture water deficit is one of the most limiting factors to the maximum yield obtained. Genotypes identification with drought tolerance capacity is fundamental to solve this problem. The objective in this paper was analyze the physiological quality and physiological and biochemical responses of soybeans cultivars (MG/BR 46 Conquista, UFUS Carajás, UFUS Impacta, UFUS Riqueza and UFUS Xavante) submitted to water stress with PEG 6000 solutions in different levels of osmotic potentials (0; -0,1; -0,2; -0,3 and -0,4 MPa). Physiological quality of cultivars were evaluated by seedling length test and fresh and dry biomass. The biochemical responses were evaluated by detection of indol-acetic acid (IAA), by saccharose content and seedling water transportation. UFUS Riqueza presented the best performance in physiological quality tests, saccharose content, absorption and water absorption velocity in seedling. UFUS Xavante showed the highest IAA's concentration and the greater weight of seedling in water transportation test.

Efeitos da polpa do fruto de annona crassiflora mart., nos parâmetros bioquímicos e na carcinogênese de colon de ratos

A. crassiflora Mart. a Brazilian savannah fruit, is a source of phytochemical compounds that possess a wide array of biological activities, including free radical scavenging. This native fruit proved to potentialize the mutagenic process in previous in vivo investigations. The aim of the present study was to investigate the effects of A. crassiflora Mart. pulp intake on colonic cell proliferation and on the development of Aberrant Crypt Foci (ACF) in male Wistar rats. The animals were fed with either a commercial diet or a diet supplemented with A. crassiflora Mart. pulp mixed in 1%, 10% or 20% (w/w) for 4 weeks or 20 weeks. The carcinogen 1,2-dimethylhydrazine dihydrochloride (4 doses, 40 mg kg-1 each) was used to induce colonic ACF. After euthanasia, the blood, liver and colon samples were collected for biochemical determinations, oxidative stress or ACF development analysis, respectively. Immunohistochemical analyses of the colonic mucosa were performed using antibodies against proliferating cell nuclear antigen (PCNA) in normal-appearing colonic crypt and β-catenin in ACF. There was no ACF development in the colon from groups treated with A. crassiflora Mart. pulp. Also, the biochemical and oxidative stress analysis, PCNA labeling and ACF development (number, multiplicity or cellular localization of β-catenin) were unchanged as a result of marolo pulp intake. Thus, the present results suggest that A. crassiflora Mart. pulp intake did not exert any protective effect in the colon carcinogenesis induced by DMH in rats.
