An ethno-medicinal investigation was conducted to highlights the traditional knowledge of medicinal plants being used by the tribe in West and South district of Tripura. This paper provides information about the different uses of plants used in their primary health care system. Tripura is a small north-eastern state of India and also a part of both Himalayan and Indo-Burma biodiversity region. It is a goldmine of medicinal plants and use of different plants in tribal traditional heath care systems has long history. Nineteen different tribes in Tripura, depend on natural resources at a great extent. This paper documented 113 medicinal plant species from 56 families along with their botanical name, local name, family name, habit, medicinal parts used, and traditional usage of application. The dominant families are Euphorbiaceae (7 species), Apocynaceae (6 species), Fabaceae and Rubiaceae (5 species each), Caesalpiniaceae, Asteraceae, Liliaceae and Verbenaceae (4 species each), Combretaceae, Labiatae, Malvaceae, Rutaceae and Zingiberaceae (3 species each). Tribes of Tripura have rich traditional knowledge on plant based medicine. Different parts of the plants in crude form/plant extracts/decoctions/infusion or pastes are employed in diverse veterinary and human diseases by the tribe’s of Tripura in daily life.  相似文献   

Coupling of action potential activity between unmyelinated fibers in the peripheral nerve of monkey   总被引：1，自引：0，他引：1  

R A Meyer  S N Raja  J N Campbell 《Science (New York, N.Y.)》1985,227(4683):184-187

Bidirectional coupling of action potential activity occurs between unmyelinated fibers in the normal peripheral nerve of monkey. The site of coupling is near the cutaneous nociceptive receptor associated with one of the fibers. This coupling could be due to an electrical synapse and could provide the basis for the flare associated with the axon reflex.  相似文献   

Cucumber performance is improved by inoculation with plant growth-promoting microorganisms     

Sang-Mo Kang  Ramalingam Radhakrishnan  Young-Hyun You  Abdul Latif Khan  Jae-Man Park  Soek-Min Lee 《Acta Agriculturae Scandinavica, Section B - Plant Soil Science》2013,63(1):36-44

We investigated the effects of inoculation of Rhodobacter sphaeroides, Lactobacillus plantarum, and Saccharomyces cerevisiae on cucumber plant growth promotion and on the contents of plant hormones, amino acids, and mineral nutrients. We showed that treatment with all three bio-inoculants significantly increased the shoot length, root length, shoot fresh weight, shoot dry weight, and chlorophyll content, via secretion of indole acetic acid and/or organic acids. Inoculation with R. sphaeroides had more favorable effect on plant growth than did inoculation with L. plantarum or S. cerevisiae, by significantly enhancing the gibberellin and reducing the abscisic acid contents. The results of amino acid analysis revealed that inoculation with R. sphaeroides, L. plantarum, and S. cerevisiae generally increased the contents of 17 amino acids, namely, aspartic acid, threonine, serine, glutamic acid, glycine, alanine, cysteine, valine, methionine, isoleucine, leucine, tyrosine, phenylalanine, lysine, histidine, arginine, and proline. With the exception of cysteine, all these amino acids were present in higher concentrations in plants inoculated with R. sphaeroides than in control plants or in plants inoculated with L. plantarum and S. cerevisiae. Furthermore, inoculation with R. sphaeroides significantly increased the calcium, potassium, magnesium, and phosphate contents. Our results suggest that the use of R. sphaeroides, L. plantarum, and S. cerevisiae in agricultural fields can improve plant growth. Moreover, inoculation of cucumber plants with R. sphaeroides regulates plant functional metabolites, thereby promoting plant growth.  相似文献   

Potential for nitrate reduction in wheat (triticum aestivum L.)     

P. Ananda Kumar  H.L. Grover  Y.P. Abrol 《Journal of plant nutrition》2013,36(5):843-852

Following the prevalent agronomic practice of applying N fertilizer in two splits at optimum levels recommended for maximum yield viz. 120 kg N ha, to two wheat (Triticum aestlvum L.) cultivars, which differ in in vivo nitrate reductase (NR) activity, it was observed that the activity is high in the first formed leaf blades and declines in the successively formed ones. Enhancement in the activity subsequent to incubation of excised leaf blades in NO₃ ^‐ suggests that the substrate (NO^‐ ₃) is limiting and that the leaf blades, particularly the upper ones, have the potential to reduce additional amounts of NO₃ ^‐. High NR cultivar has greater potential than the low NR cultivar. The studies suggest that it may be possible to increase the NO₃ ^‐ moles reduced and thus enhance the reduced N content in case the nitrogen is available at later stages of growth.  相似文献   

Influence of the antibacterial herbs, Solanum trilobatum, Andrographis paniculata and Psoralea corylifolia on the survival, growth and bacterial load of Penaeus monodon post larvae     

T. Citarasu  K. Venkatramalingam  M. Micheal Babu  R. Raja Jeya Sekar  M. Petermarian 《Aquaculture International》2003,11(6):581-595

The indiscriminate use of antibiotics and chemicals in shrimp hatcheries has led to biomagnification and that in turn could lead to rejection of a whole consignment. The application of the bioencapsulation technique as a tool for curative treatment in shrimp larvae was investigated. Herbs having antibacterial properties such as Solanum trilobatum, Andrographis paniculata and Psoralea corylifolia (methanolic extracts) were bioencapsulated in Artemia and fed to Penaeus monodon post larvae PL 1–25. The post larvae were reared in a medium inoculated with pathogenic bacteria such as Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella typhi and Vibrio sp. Post larvae reared in the non-inoculated water and fed with non-enriched Artemia exhibited 90% survival, highest specific growth rate (12.43%) and reduced bacterial load. P. monodon reared in the bacterial inoculated water and fed with the non-enriched Artemia exhibited the lowest survival (10–30%), specific growth rate (8.42–9.1%) and increased bacterial load (2.86 × 10³ to 3.76 × 10⁵ cfu/g). The methanolic extracts of the herbs helped to increase survival and specific growth rate and reduced bacterial load in the P. monodon culture system. Among the three herbal extracts, P. corylifolia enriched Artemia fed post larvae showed the tendency to higher survival (>50%), growth rate (11.5 averaged) and low bacterial load (1.12 × 10⁵ cfu/g). This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

A Shark Liver Gene-Derived Active Peptide Expressed in the Silkworm,Bombyx mori: Preliminary Studies for Oral Administration of the Recombinant Protein     

Yunlong Liu  Ying Chen  Jianqing Chen  Wenping Zhang  Qing Sheng  Jian Chen  Wei Yu  Zuoming Nie  Yaozhou Zhang  Wutong Wu  Lisha Wang  Inthrani Raja Indran  Jun Li  Lian Qian  Zhengbing Lv 《Marine drugs》2013,11(5):1492-1505

Active peptide from shark liver (APSL) is a cytokine from Chiloscyllium plagiosum that can stimulate liver regeneration and protects the pancreas. To study the effect of orally administered recombinant APSL (rAPSL) on an animal model of type 2 diabetes mellitus, the APSL gene was cloned, and APSL was expressed in Bombyx mori N cells (BmN cells), silkworm larvae and silkworm pupae using the silkworm baculovirus expression vector system (BEVS). It was demonstrated that rAPSL was able to significantly reduce the blood glucose level in mice with type 2 diabetes induced by streptozotocin. The analysis of paraffin sections of mouse pancreatic tissues revealed that rAPSL could effectively protect mouse islets from streptozotocin-induced lesions. Compared with the powder prepared from normal silkworm pupae, the powder prepared from pupae expressing rAPSL exhibited greater protective effects, and these results suggest that rAPSL has potential uses as an oral drug for the treatment of diabetes mellitus in the future.  相似文献   

An integrated multivariate approach to net blotch of barley: Virulence quantification,pathotyping and a breeding strategy for disease resistance     

Rajaâ Jebbouj  Brahim El Yousfi 《European journal of plant pathology / European Foundation for Plant Pathology》2010,127(4):521-544

Knowledge of pathotype diversity and virulence in local populations of Pyrenophora teres is a prerequisite to screening for durable resistance to net blotch. The current study aimed to quantify the virulence level of Moroccan isolates, identify and designate existing pathotypes, and select resistant genotypes. We developed a method for virulence quantification of P. teres isolates based on a conversion of infection responses into frequencies for use in correspondence analysis. Coordinates of the first axis of this analysis had a virulence spectrum and ranked isolates from virulent to avirulent. Mixed model analysis was also devised for virulence quantification. Coordinates of the first dimension of correspondence analysis were linearly correlated to BLUPs (Best Linear Unbiased Predictors) of the mixed model. A genotype by genotype by environment model (GGE) coupled with cluster analysis differentiated P. teres isolates into ten and nine pathotypes for net- and spot-forms respectively. Populations of these two forms were dissimilar in terms of classes of virulence. For P. teres f. maculata, avirulent, moderately virulent and highly virulent isolates represented one-third of the population, whereas 90% of P. teres f. teres population was composed of avirulent to moderately avirulent isolates. Barley differential sets were subsequently reduced to two new sets that simplified pathotyping through a key code based on resistant or susceptible reactions. Dendrograms of cluster analysis based on GGE analysis depicted the stability of a genotype’s reactions across all isolates, and using only resistant cultivars as sources of resistance to control net blotch disease would, based on this analysis, fail to control all pathotypes. Therefore, we propose an alternative breeding strategy to control net blotch effectively.  相似文献   

Epidemiological Investigation of Brackish Water Culture Systems in West Bengal,India     

R. Ananda Raja  A. Panigrahi  Sujeet Kumar 《Journal Of Applied Aquaculture》2013,25(1):49-59

An epidemiological investigation was done in brackish water culture systems in three coastal districts of West Bengal. A total of 198 farms were randomly surveyed with a structured questionnaire. The data showed that there was a significant difference in outbreak of white spot disease (WSD) (p < 0.01), shell-associated problems (p < 0.01), and gill-associated problems (p < 0.05) among the culture systems. Among all systems, stunted and uneven growth and white fecal disease (only in shrimp monoculture) were the dominant emerging disorders. WSD remained the most prevalent disease. Some farms tested (polymerase chain reaction [PCR]) positive for WSD, but the animals were apparently healthy. Chlorination, use of PCR screening, application of immunostimulants, and strict bio-security measures play major roles in containing disease outbreaks.  相似文献   

Polymorphism of growth hormone receptor (<Emphasis Type="Italic">GHR</Emphasis>) gene in Nilagiri sheep     

Amiya Ranjan Sahu  V. Jeichitra  R. Rajendran  A. Raja 《Tropical animal health and production》2017,49(2):281-285

The allelic variation in the regulatory sequence of growth hormone receptor (GHR) gene influences the growth traits of sheep. A study was carried out to find out the polymorphisms associated with exon 10 of GHR gene and its association with growth traits of Nilagiri sheep. The blood samples were collected from Nilagiri sheep (n?=?103) reared at Sheep Breeding Research Station, Sandynallah, Tamil Nadu, India. DNA was isolated using the phenol-chloroform extraction procedure and eight samples having amplified product of part of exon 10 (895 bp) sequenced. The results indicated transitions of nucleotide G>A at loci G177624A and G177878A. The genotyping frequencies estimated using the tetra-primer amplification refractory mutation system-PCR for GG, GA and AA were 0.262, 0.544 and 0.194, and 0.349, 0.505 and 0.146, respectively. The estimated allele frequencies of G and A nucleotides were 0.5340 and 0.4660, and 0.6015 and 0.3985, respectively, at loci G177624A and G177878A. The effects of both the mutations on growth-related traits viz., birth, weaning (3 months) 6, 9 and 12 months weight in Nilagiri sheep were found to be non-significant. This can be a novel approach to assess growth of sheep using the mutation in GHR gene. Thus, this approach can be useful for further investigation as a molecular marker associated with genetic improvement.  相似文献
