At the different concentration of the Weike of 1:200,1:280, 1: 400,1:800, at the different concentration of the Fanfuluyi of 1:320,1:600,1:800 and at the different concentration of the Qilu of 1:200,1:400 had complete inactivation to H5N1 Avian Influenza Virus in laboratory.
(3) inhibited I A inactivation, inactivation time constant from (42 2±10 1) ms to (81 9±35 0) ms( n=10,P< 0 05),half maxi inactivation voltage from (-87 5±12 6) mV to (-99 8±2 1) mV ( n=10, P< 0 01);
Conclusion: The bulk of Hepatitis B vaccine with 1/2000 and 1/4000 of the formaldehyde solution in the condition of 37℃ for 72 hours could inactivate measles virus and VSV virus effectively
1. After protection by 0.35mmol/L rutin, the cooperation treatment of 6 μg/ml AO and 4500J/m2 UVA irradiation could effectively inactivate the bacteriophage f2 in plasma and had little influence on the component of plasma.
1. 终浓度为6μg/ml的 AO 处理30min后,再经剂量为4500J/m2 UVA照射,血浆中f2噬菌体的灭活能达到6个对数级以上,在光淬灭剂(0.35mmol/L芸香苷)的作用下,血浆中主要蛋白的含量、分子量、生物活性无显著变化。
The results show that the best in the tested nanometer paints,was ZB—08 —12, whose inhibitory rate to Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, and Candida albicans were 82.20%, 87.86%, 53.06%, 63.20% and 88.76% respectively, and the average sorption rate and virucidal rate to parainfluenza virus were 87.50% and 99.60% respectively.
The kinetic constants, energies of activation and inactivation of the enzyme complex, and pH optimum (7.0 ± 0.1) at which this complex had the maximum proteolytic activity were determined.
Collectively, these studies identify the mechanism by which an important tumor suppressor gene, FHIT is inactivated specifically in human CRC contributing to our understanding of the mechanism of colorectal carcinogenesis.
Sulfotransferase 1A1 (SULT1A1) and UDP-glucuronosyltransferase 1A1 (UGT1A1) conjugate and inactivate both estrogens and their metabolites, thus preventing estrogen-mediated mitosis and mutagenesis.
The anionic derivative chitosan sulfate andN-succinate-6-O-sulfate did not inactivate the phage, did not influence bacterial growth, and did not inhibit the process of viral infection.
The hypothesis is discussed that the short-term reversible adhesion of cells is regulated with the involvement of a mixture of hydrocarbons, which inactivate the functional activity of bacterial adhesins, and proteases, which digest these adhesins.
We were the first to establish that PABA is an inducer of endogenous interferon and immunomodulator and displays a virucidal, synergistic antiviral effect when combined with chemical drugs and the properties of a direct anticoagulant.
Two strains of Capromyces Pleuropneumoniae were propagated in and passed through embryonated eggs for about 80 generations by means of yolk-sac inoculation. Both the strains retained their full virulence in the first 5-6 generations as titrated in goats. Formalized vaccine prepared from the embryonated tissue of the first 3-7 generations combined with aluminum hydroxide gel did not protect all of the goats vaccinated from artificial challenge. However, by continuously passing through embryonated eggs, both ...
It is well known that schizandra can markedly reduce the SGPT activity both in patients with hepaticdisease and in experimental animals, but the mechanism remains obscure.Our preliminary study in rabbits reveals that:Schizandra does not directly inactivate the SGPT activity to any significant degree nor does it reduce the permeability of the liver cell membrane for GPT release. In addition, schizandra does not markedly increase the SGPT clearance nor does it significantly protect the liver cell from CGl_4 i...
Summary Virus isolated from bovine with epizootic fever in Beijing has been identified as probable rhabdovirus on the basis of morphological and physico—chemical propertis, 76AM strain of bovine epizootic fever virus has been propagated in baby mice and then adapted in BHK_(21) (c13) cell line. Tne following properties of the virus have been charaterized: virions are bullet shapcd, measuring 85nm in diameter and 170nm in length, containing RNA. This virion with an envelope of 11 nm thickness and studded w...
