The aim of this study was to investigate whether bovine faeces could replace rumen liquor collected from fistulated sheep in the determination of organic matter digestibility (OMD) of forages in vitro. The first experiment compared two inocula that had been prepared by mixing 83 and 333 g of cattle faeces with 1 litre of artificial saliva according to the first stage of the in vitro technique of Tilley and Terry (Journal of the British Grassland Society,18, 104–111, 1963). Inocula made from 333 g of faeces gave higher values of OMD than that prepared from 83 g of faeces and was used in subsequent studies. When a 48‐h acid pepsin digestion, the second stage of the
Tilley and Terry (1963) technique, was included, the OMD values and the ease of filtering of undigested residues were increased. The second experiment compared digestibility determined with inocula produced from faeces with that produced from rumen liquor. The OMD of a ryegrass hay determined with an inoculum prepared from faeces was 0·468 compared with 0·528 when using an inoculum prepared from rumen liquor. The third experiment investigated the accuracy of estimating the OMD of eight contrasting forages determined using rumen liquor from three sheep (y) and faeces from two cows (x). All regressions were significant (P < 0·001) and had residual standard deviations (r.s.d.) of between ±0·019 and ±0·022. The final study compared faeces collected from cattle fed with either hay or concentrates. The OMD of forage was higher from the hay‐fed animals, but the r.s.d. values of the regressions were similar. It was concluded that cattle faeces shows potential as an alternative to rumen liquor collected from rumen‐fistulated sheep for use in the in vitro digestibility assay of forages.
The crude ethanol and methanol extracts of Tamarindus indica seeds have been investigated to evaluate their antibacterial and cytotoxic potentialities. Extracts were screened for their antibacterial activity against both gram positive and negative bacteria primarily by disc diffusion method and then minimum inhibitory concentration (MIC) assay. Besides the cytotoxic activity were screened by using brine shrimp lethality bioassay. The average zone of inhibition for ethanol extract of seeds of tamarind was ranged from 7.5 - 13.5 mm for 500 μg/disc. And for methanol extract the zone of inhibition was ranged from 6.5 - 13.25 mm for 500 μg/disc. From MIC assay minimum inhibitory concentration was found 1.25 mg/ml for ethanol and 0.625 mg/ml for methanol extract. The minimum bactericidal concentration was found 2.5 mg/ml for ethanol and 1.25 mg/ml for methanol extract. Compared to vincristine sulfate (with LC50 of 0.99 μg/ml) both ethanol and methanol extract of T. indica seeds showed toxicity lower than 100 μg/ml and greater than 30 μg/ml. The study confirms greater antibacterial activity of T. indica seed extracts with moderate cytotoxic activity. This study thus demands isolation of active principles and thorough bioassays.

Femoral shaft fracture is an uncommon birth trauma. Bryant's Traction followed by spica cast is an acceptable method of treatment of femoral shaft fracture 0-18 month's age group. Here we treated 30 cases of neonatal femur fracture during birth with only Bryant's Traction of both legs for 3 weeks in hospital. We retrospectively reviewed all neonatal femur fractures occurred during birth admitted in FMCH during a two and half years period. All patients were followed up monthly for 3 months and 6 monthly for 2 years. All fractures healed satisfactorily clinically and radiographically and with no residual deformity, limb length discrepancy or functional impairment. Parents were highly satisfied with the method and its result. It is very simple method and could be safely carried out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
