Constituintes sangüíneos de vacas das raças Nelore (Bos indicus) e Holandesa (Bos taurus) e de bubalinas (Bubalus bubalis) da raça Murrah durante a gestação, no dia do parto e no puerpério

Blood constituents of Nelore, Hosltein and buffalo cows were determined during pregnancy, at the time of calving and at post-partum. It was verified that. 1. The pregnancy and post-partum periods had no influence in the erythrocyte values, but at calving the red blood cell counts and hemoglobin levels of Holstein and buffalo cows were lower than for Nelore cattle; 2. leukocyte counts were similar among groups; 3. total protein levels of Nelore cows were lower than Holstein and buffalo. The albumin levels were rite lowest at rite time of calving compared to late pregnancy; 4. glicose levels were lower ill buffalo cows during pregnancy as compared with Holstein cows. The glicemia of Nelore cows was lower as compared to Holstein cow's irt late pregnancy; 5. urea and creatinine levels were higher in buffalo cows than cattle. The urea and creatinine levels were greater in buffalo cows with maximum values at the post-partum and at the parturition, respectively; 6. bilirrubin levels were higher in bovine than buffalo cows; 7. aspartate aminotransferase activity was greater in buffalo cows and increased at the time of calving; 8. alkaline phosphatase activity was increased during pregnancy and decreased after the time of calving; 9. gammnglutamyltransferase activity,vas the highest for buffalo cows after calving; IO. calcium levels were the highest for Holstein cows at the post-partum and the phosphorus levels were higher in buffalo cows, which had the highest magnesium levels at the parturation.

Constituintes sangüíneos de bovinos lactantes, desmamados e adultos das raças Nelore (Bos indicus) e Holandesa (Bos taurus) e de bubalinos (Bubalus bubalis) da raça Murrah

Blood samples from lactating, weaned and adult Holstein-Fresiean and Nelore cattle and Murrah buffaloes were tested through the study of hemogram and serum constituents. Red cell and leukocyte counts, and blood pH, fibrinogen, glucose, calcium, and phosphorus levels were similar in cattle and buffalo. Total protein, urea, creatinine, hemoglobin, magnesium, iron and aspartato aminotransferase and alanine aminotransferase activities were higher in buffalo than cattle. Leukocyte counts were higher for weaned Holstein cattle than for Nelore cattle but similar to buffalo and Nelore cattle had the lowest neutrophil counts. Bilirrubin levels were lower for buffalo than for cattle. Phosphatase alkalyne activities were lower for weaned buffalo than for other animals. Gammaglutamyltransferase activities were the highest for lactating and weaned buffalo.

Decomposição de argilas em forno de microondas e determinação simultânea dos seus constituintes principais por espectrometria de emissão óptica em plasma indutivamente acoplado

ANALYSIS OF CLAYS BY INDUCTIVELY COUPLED PLASMA OPTICAL EMISSION SPECTROMETRY AFTER CLOSED-VESSEL MICROWAVE-ASSISTED ACID DECOMPOSITION. In this work a closed-vessel microwave-assisted acid decomposition procedure for clays was developed. Aluminum, Ca, Fe, K, Mg, Na, Si, and Ti were determined in clay digestates by inductively coupled plasma optical emission spectrometry. The most critical parameter for total decomposition of clays was the composition of the reagent mixture. The applied power and the heating time exerted a less critical influence. Best decomposition conditions were attained using a reagent mixture containing 4 mL aqua regia plus 3 mL HF and the heating program was implemented in 12 min. The accuracy of the results was demonstrated using two standard reference materials and a paired t-test showed a good agreement between determined and certified values at a 95% confidence level.

Constituintes de Sorocea bomplandii Baillon

The chemical investigation of the leaves of Sorocea bomplandii Baillon (Moraceae) led to the identification of pentacyclic triterpenes, fatty acid ester and isoprenoids. Chromatographyc comparison between the infusion S. bomplandii with that of Maytenus aquifolium - a Celastraceae with proved antiulcer activity - has shown that they have different compositions: the first one is based on sugars and the last one is based on flavonoid glycosides.
