The objective of this study was to compare ileal and total tract nutrient digestibilities and fecal characteristics of dogs fed selected animal and plant protein sources incorporated into grain-based diets. Four crude protein sources--soybean meal (SBM), poultry meal (PM), poultry by-product meal (PBPM), and beef and bone meal (BBM)--were fed to four ileal cannulated dogs in a 4 x 4 Latin square design. Intakes of dry matter, organic matter, crude protein, and fat by dogs were similar. Total dietary fiber (TDF) intake was highest for the SBM treatment compared to other treatments. Ileal digestibilities of DM, OM, CP, fat, and TDF were not affected by treatment. Total tract digestibility of DM was lower for the BBM and SBM diets, while OM digestibility was lower for the SBM treatment only. Total tract CP digestibility was similar for BBM, PBPM, and SBM treatments and was higher for the PM treatment. As-is fecal excretion [g/d] was greater when dogs received the SBM treatment. Fecal output on a DM basis was higher for the SBM treatment compared to the other treatments. All diets were well utilized by the dogs as assessed by ileal and total tract digestibility data and fecal characteristics.  相似文献   

Hepatoprotective activity of Calotropis procera flowers against paracetamol-induced hepatic injury in rats   总被引：2，自引：0，他引：2  

Ramachandra Setty S  Quereshi AA  Viswanath Swamy AH  Patil T  Prakash T  Prabhu K  Veeran Gouda A 《Fitoterapia》2007,78(7-8):451-454

Hydro-ethanolic extract (70%) of Calotropis procera flowers was prepared and tested for its hepatoprotective effect against paracetamol-induced hepatitis in rats. Alteration in the levels of biochemical markers of hepatic damage like SGPT, SGOT, ALP, bilirubin, cholesterol, HDL and tissue GSH were tested in both treated and untreated groups. Paracetamol (2 g/kg) has enhanced the SGPT, SGOT, ALP, bilirubin and cholesterol levels and reduced the serum levels of HDL and tissue level of GSH. Treatment with hydro-ethanolic extract of C. procera flowers (200 mg/kg and 400 mg/kg) has brought back the altered levels of biochemical markers to the near normal levels in the dose dependent manner.  相似文献   

Progeny evaluation of Jatropha curcas and Pongamia pinnata with comparison to bioproductivity and biodiesel parameters

Progeny studies of Jatropha curcas and Pongamia pinnata were carried with respect to bioproductivity,pod and seed characters which is one of the selection methods in tree improvement programmes. Variations in bioproductivity and biodiesel parameters of both the plants were compared every 6 months for 4 years of investigation and analyzed by analysis of variance and correlation coefficient by Pearson’s method using software Graphpad instat 3.06(for Windows and Mac). P. pinnata has better germination rate(71.4 %), 100 pod weight(PW)(311.59 g) and 100 seed weight(SW)(173.46 g) as compared to J. curcas for germination rate(43.2 %), 100 PW(111.29 g) and 100 SW(67.46 g). P. pinnata has strong correlation for plant height to canopy growth(CG)(0.948), collar diameter(CD)(0.994), number of branches per plant(NBP)(0.995) and to number of leaves per branch(NLB)(0.862) as compared to J.curcas which showed good correlation among plant height to CG(0.976), CD(0.970), NBP(0.988), NLB(0.920) and to number of pods per branch(0.657). However, J. curcas depicted negative correlation for pod breadth to seed length(SL)(-0.447), seed breadth(-0.248) and to seed thickness(ST)(-0.364) and among the 100 PW to SL(-0.199), ST(-0.220) and to 100 SW(-0.704). About 4 kg of P. pinnata seeds were required for each liter of crude oil which yields896 ml of biodiesel on transesterification as compared to5.66 kg of J. curcas seeds for a liter of crude oil, producing about 663 ml of biodiesel. The quality of biodiesel meets the major specification of American Society for Testing and Materials(ASTM) standards for biodiesel. The crude glycerin and seed cake obtained as byproduct during biodiesel production were also measured which can be purified and used in composting, animal feeds, pharmaceuticals and cosmetic industries.  相似文献   

In vitro and in vivo pathogenicity studies of Pasteurella multocida strains harbouring different ompA   总被引：1，自引：0，他引：1

Pasteurella multocida is a pathogenic, Gram-negative bacterium that is commonly found as normal flora in nasopharynx of variety of wild and domestic animals. Numerous virulence factors have been described for P. multocida isolates which include adherence and colonization factors, iron-regulated and acquisition proteins, extracellular enzymes such as neuraminidase, lipopolysaccharide (LPS), capsule and a variety of outer membrane proteins (Omp). OmpA has a significant role in stabilizing the cell envelope structure by providing physical linkage between the outer membrane & peptidoglycan. It has been shown to mediate P. multocida -host cells interaction via heparin and/or fibronectin binding and therefore act as an important invasive molecule which could determine the final outcome of initial infection. Comparative nucleotide sequence analysis of ompA gene of P. multocida has revealed that despite extensive genetic diversity in ompA of P. multocida, most sequences could be classified into two major allele classes namely ompA allele (I) and allele (II). The P. multocida recovered from nasal cavity of bovine and belonging to two ompA classes were tested for their differential virulence. In vitro pathogenicity studies on Madin Darby Bovine Kidney (MDBK) cell line employing adhesion and invasion assays indicated that P. multocida strain with ompA (I) is more invasive than P. multocida strain with ompA (II). In vivo studies in mice further reiterated that the isolates harbouring ompA(I) were comparatively more virulent to isolates harbouring ompA (II).  相似文献   

Citrus pectin: characterization and inhibitory effect on fibroblast growth factor-receptor interaction.     

Y Liu  H Ahmad  Y Luo  D T Gardiner  R S Gunasekera  W L McKeehan  B S Patil 《Journal of agricultural and food chemistry》2001,49(6):3051-3057

This study was undertaken to characterize the pectin from four citrus species and to determine their in vitro inhibitory activities on the binding of fibroblast growth factor (FGF) to the FGF receptor (FGFR). Pectin from various parts of lemon, grapefruit, tangerine, and orange were isolated and characterized. Tangerine had the highest pectin content among the four citrus species. Segment membrane contained as much as or more pectin than flavedo/albedo. Anhydrogalacturonic content was highest in pectin from segment membrane of tangerine and flavedo/albedo of grapefruit. Lemon pectin contained the highest methoxyl content (MC), and grapefruit contained the largest proportion of lower molecular weight (<10000 Da) pectin. Tangerine contained the highest neutral sugar in both flavedo/albedo and segment membrane. The interdependency of heparin on factor-receptor interaction provides a means for identifying new antagonists of growth factor activity and thus for treatment of various diseases. These results showed that pectin significantly inhibited the binding of FGF-1 to FGFR1 in the presence of 0.1 microg/mL heparin. The pectin from the segment membrane of lemon was the most potent inhibitor. The inhibition activity was significantly correlated with sugar content, MC, and size of pectin. Kinetic studies revealed a competitive nature of pectin inhibition with the heparin, a crucial component of the FGF signal transduction process. The observation that the heparin-dependent biological activity of FGF signal transduction is antagonized by citrus pectin should be further investigated for the use of these pectins as anti-growth factor agents for potential health benefits.  相似文献   

Performance of wastewater stabilization ponds at different depths     

B. B. Hosetti  H. S. Patil 《Water, air, and soil pollution》1987,34(2):191-198

Investigations were made on wastewater ponds (cement cisterns) operated at 1.22, 1.83, and 2.44 m depths. Results revealed the layering of microorganisms at various depths. BOD and nutrient values and bacterial counts were maximum in the bottom layers and minimum at the surface in all the ponds. Concomitant with these variations, increases in pH and DO content were observed at the upper layers of the ponds. The activities of catalase, phosphatase, protease and amylase were directly related to microbial growth and activity. Low enzyme activity was recorded in the upper layers, whereas it increase with the increase in depth of the pond. From the present study, it is inferred that the pond depth could be increased beyond a generally acceptable value of 1.22 m particularly in tropical countries where enough light is available.  相似文献   

Variation in the ribosomal RNA units of the generaLens andCicer   总被引：2，自引：0，他引：2  

P. B. Patil  P. L. Vrinten  G. J. Scoles  A. E. Slinkard 《Euphytica》1995,83(1):33-42

Summary Investigation of the organization of the tandemly repeated 5S and 18–25S ribosomal RNA (rRNA) genes was carried out on members of the generaLens andCicer using restriction endonuclease digestion and Southern hybridization. The 5S rRNA unit (gene+spacer) inLens (0.38 to 0.50 kb) andCicer 0.50 to 0.44 kb) is the largest among the legumes. InL. nigricans andL. culinaris ssp.odemensis a second repeat size was detected. Restriction maps for the 18–25S units ofLens andCicer species were developed. The 18–25S rRNA unit varied from 8.3 to 9.8 kb inLens and 10.5 to 11.4 kb inCicer. The only detectable variability in theLens andCicer 18–25S rRNA unit was in the length of the intergenic spacer (IGS) region, except for a HindIII site in the IGS region ofL. nigricans ssp.nigricans and in allCicer species.Similarities in the size of both 5S and 18–25S rRNA units were noted betweenL. culinaris ssp.culinaris andL. culinaris ssp.orientalis, which supports previous evidence thatL. culinaris ssp.orientalis is the progenitor of the cultivated lentil. Differences in the arrangement of both 5S and 18–25S rRNA units were noted betweenL. nigricans ssp.nigricans andL. nigricans ssp.ervoides, indicating either divergent evolution of these subspecies or alternatively incorrect taxonomy.On the basis of the size of the 5S rRNA unit,C. bijugum, C. chorassanicum andC. echinospermum formed a group with a slightly smaller unit than the otherCicer species. Similarities in the length of both 5S and 18–25S rRNA units ofC. arietinum andC. reticulatum possibly confirmC. reticulatum as the progenitor ofC. arietinum. Cicer cuneatum has a smaller 18–25S rRNA unit than the otherCicer species as a result of a smaller intergenic spacer.  相似文献   

Effect of Boron on Seed Yield in Lucerne (Medicago sativa L.)     

S. M. Misra  B. D. Patil 《Journal of Agronomy and Crop Science》1987,158(1):34-37

The present study aimed at studying the effect of boron on pollen characteristics, translocation of water soluble sugars and its importance as a specific nutrient for seed production in lucerne. Aquous solutions of borax (0, 2500, 5000, 7500, 10 000 and 20 000 ppm) were sprayed at flowering stage. After 20 days, the fresh flowers were collected from the plants of all the treatments separately. The pollen was dusted on glass slides containing Muntzing's mixture for staining. After 6 hours, the data on pollen size, stainability and germination were recorded in 10 randomly selected microscopic fields. The estimation of water soluble sugars and boron content in flowers was done by standard methods. Data on grains per pod, grains per inflorescence and 1000 seed weight were recorded at seed maturity. With increasing rates of applied B, pollen germination, water soluble sugars, boron content and number of seeds per pod and per inflorescence increased but pollen fertility decreased. The pollen size and 1000 seed weight was not affected by boron concentrations. The results indicate that boron plays a definite role in increasing the seed yields through stimulating the physiological processes during reproductive phase.  相似文献   

Differential inhibition responses caused by DDT on oligomycin-sensitive Mg2+-ATPase activity: Nature of the requirements for DDT sensitivity     

T.N. Patil  Robert B. Koch 《Pesticide biochemistry and physiology》1979,12(3):205-215

Earlier communications from this laboratory have shown that DDT inhibited oligomycin-sensitive Mg²⁺-ATPase (EC 3.6.1.3) but that its active component, F₁, was not affected. In the present investigation evidence has been obtained to determine the nature of the requirements for DDT sensitivity. The results showed that DDT sensitivity was conferred to F₁ from pig heart mitochondrial preparations when it was bound to F₀ from the same preparation. The F₁ from house fly (Musca domestica L) thorax was able to bind to F₀ from pig heart. This combination showed similar sensitivity to that of the original F₁-F₀ combination from pig heart mitochondria. However, when F₁ from pig heart mitochondria was incorporated into F₀ depleted in oligomycin sensitivity-conferring protein (OSCP) from the same source, the resulting ATPase activity was insensitive to DDT. Addition of crude (50–200 μg) or purified (5–20 μg) OSCP in the above preparation restored DDT sensitivity. Presence of dioleyl or dipalmitoyl phosphatidyl choline or Triton X-100 in the reaction medium antagonized the DDT inhibitions. Depletion of phospholipids from submitochondrial membrane preparations (SMP) decreased ATPase activity. Addition of dioleyl or soybean phosphatidyl choline to this lipid-depleted preparation restored DDT sensitivity. Evidence presented suggests that DDT acted on F₁ in association with one or more membrane components and that OSCP and phospholipid were essential for DDT sensitivity.  相似文献
