A análise morfométrica para avaliar a taxa de progressão da fibrose hepática na hepatite C crônica após o transplante renal: uma série de casos

The real role of renal transplantation in hepatic fi brosis progression caused by hepatitis C virus is still unpredictable. Histological evaluation of the liver is the best form to estimate fi brosis evolution, although semiquantitative analysis carries important limitations. Objective: To apply a morphometric quantitative assay on hepatic fi brosis progression in renal recipients with hepatits C. Methods: Thirty patients were initially evaluated, but only seven were included. They underwent the fi rst biopsy near the transplantation date and the second biopsy at least 4 years later. The immunosuppressant therapy adopted in all cases was azatioprine and micofenolate. Fibrosis progression rate (FPR) was calculated before and after the surgery date in each patient according to Metavir score and morphometric analysis. Results: The FPR calculated by Metavir score showed no statistical difference between pre- and post-transplantation (p=0.9). The FPR calculated by the morphometric analysis was 0.58 ± 0.78 before transplantation and 3.0 ± 3.3 after the surgery, with statistical signi- fi cance between these values (p=0.0026). Conclusion: In the sample assessed, the progression of hepatic fi brosis was documented and quantifi ed only by the morphometric analysis, which is as a promising approach to histological evaluation of these patients.

Diâmetro folicular e taxa de prenhez em protocolo de sincronização com GnRH ou Benzoato de Estradiol no dia 0 em vacas de corte

This work aimed to evaluate the pregnancy rate and follicular diameter using EB or GnRH on the insertion of progesterone implant (D0) in lactating beef cows. Two groups were tested in two experiments. In Exp. 1 were used 61 Nelore cows divided into two groups: G-BE (n = 32) and G-GnRH (n = 29), on D0 was inserted P4 implant (CIDR ) and applied 2 mL of BE (G-BE) or 2.5 mL GnRH (G-GnRH). In D9 was performed ultrasonography (U.S.) to measure the diameter of the dominant follicle (DF) present in the ovary and the implant was removed, with concomitant administration of 2.5 mL of PGF2a and estradiol cypionate (ECP ) followed by calves removal. After 48 hours all the cows were inseminated and the calves returned. In Exp. 2 50 cows were used following the same protocol described above, but the pregnancy was assessed without performing ovarian US. There was no difference (p>0.05) in pregnancy rate between treatments, BE (55%) or GnRH (41%), but the follicular diameter was significantly higher (p<0.05) in pregnant cows treated with EB (10.7 mm vs. 8.5 mm) and in cows treated with GnRH there was no difference (p>0.05) between pregnant and no pregnant cows (11.6 mm vs. 10.2 mm). We concluded the use of GnRH on D0 did not improve the pregnancy rate in lactating beef cows and follicular diameter was greater (p <0.05) in pregnant cows compared to non-pregnant only in G-BE.

Efeito do período pós-parto sobre a taxa de prenhez de vacas de corte submetidas à IATF (Inseminação Artificial em Tempo Fixo)

This work aimed to evaluate the influence of postpartum period (precocious - of 28 to 44 days and late - of 45 to 90 days) on the bovine pregnancy rate using fixed-time AI. For that, 678 cows were divided in two groups: precocious group (G-P, n=151) and late group (G-T, n=527). The animals received CIDR® + 2 mL of estradiol benzoate (BE) in the day zero (D0). After eight days (D8) the dispositive was removed and both groups received 2.5mL PGF2α, concurrent with PGF2α injection, they received either 1.5mL of eCG or temporary calf removal (RTB). In the next day (D9), the cows received 1 mL de BE and 24 hours later, the fixed-time AI was performed with Nelore bovine semen. The calves were returned to their mothers. The pregnancy rate was not different between the groups (p>0.05), G-P=40% and G-T=48%. The results indicate that females with less than 45 days of postpartum are able to hormone protocol of fixed-time IA.

Mobilização do solo, velocidade de infiltração de água e taxa de cobertura do solo na grama esmeralda, sob manejos mecanizados

The excessive compaction of the soil observed in sod production systems, affects the physical attributes of the soil, which can influence the water infiltration into the soil and hence the rate of soil cover by turfgrasses and time of the sod production. To minimize the effects of soil compacting, some producers use soil preparation equipment that raises the soil on the surface but does not cause excessive roughness which may harm the quality of the sod. Thus, the aim of the present study was to evaluate the infiltration rate and soil cover rate due to different management mechanized in the zoysiagrass sod production. The experimental design had random plots and four replications. The treatments consisted of five mechanized managements of soil: witness (without the use of equipment); coulter blade disc harrow used once (1CB), coulter blade disc harrow used twice (2CB), surface chisel used once (1C), surface chisel and coulter blade disc harrow used once (1C + 1CB). The treatments with 2CB and 1C + 1CB provided greater basic water infiltration speed in the soil and higher rate of soil cover by the turfgrass. The rate of soil cover by turfgrass is positively correlated with water infiltration rate at 133 and 226 DAP, demonstrating the influence of managements used in zoysiagrass sod production and the increment in the infiltration rate of water. Soil preparation utilizing coulter blade disc harrow used twice or surface chisel and coulter blade disc harrow used once is recommended under the conditions this study was done.
