Rhizobium indigoferae sp. nov. and Sinorhizobium kummerowiae sp. nov., respectively isolated from Indigofera spp. and Kummerowia stipulacea. (1/12)
Forty-eight rhizobial isolates from root nodules of Indigofera and Kummerowia, two genera of annual or perennial wild legumes growing in the Loess Plateau in north-western China, were characterized by a polyphasic approach. Two main groups, cluster 1 and cluster 2, were defined based upon the results of numerical taxonomy, SDS-PAGE of whole-cell proteins and DNA relatedness. All the isolates within cluster 1 were isolated from Indigofera and they were identified as Rhizobium strains by 16S rRNA gene analysis. DNA relatedness of 29.5-48.9% was obtained among the cluster 1 isolates and the reference strains for defined Rhizobium species. Cluster 2 consisted of isolates from Kummerowia stipulacea and was identified as belonging to Sinorhizobium by 16S rRNA gene analyses. DNA relatedness varied from 5.2 to 41.7% among the isolates of cluster 2 and reference strains for Sinorhizobium species. Considering the existence of distinctive features among these two groups and related species within the genera Rhizobium and Sinorhizobium, we propose two novel species, Rhizobium indigoferae sp. nov. for cluster 1, with isolate CCBAU 71714(T) (= AS 1.3046(T)) as the type strain, and Sinorhizobium kummerowiae sp. nov. for cluster 2, with isolate CCBAU 71042(T) (= AS 1.3045(T)) as the type strain.

The chemopreventive effect of ethanol extract of Indigofera aspalathoides (EIA) on N-nitrosodiethylamine (DEN, 200 mg/kg)-induced experimental liver tumor was investigated in male Wistar rats. Oral administration of ethanol extract of Indigofera aspalathoides (250 mg/kg) effectively suppressed liver tumor induced with DEN as revealed by decrease in the levels of extend of serum glutamate pyruvate transaminase (SGPT), serum glutamate oxaloacetate transaminase (SGOT), alkaline phosphatase (ALP), total bilirubin, gamma glutamate transpeptidase (GGTP), lipid peroxidase (LPO), glutathione peroxidase (Gpx) and glutathione S-transferase (GST) with a concomitant increase in enzymatic antioxidant (superoxide dismutase and catalase) levels when compared to those in liver tumor bearing rats. The histopathological changes of liver sample were compared with respective control. Our results show a significant chemopreventive effect of EIA against DEN induced liver tumor.

A lignan and two acylphloroglucinols have been isolated from the ethyl acetate soluble fraction of the whole plant of Indigofera hetrantha. Their structures have been assigned on the basis of spectral analysis including 1D and 2D NMR techniques. Compounds 1-3 displayed promising inhibitory potential against enzyme lipoxygenase in concentration-dependent manner.

A large number of active principles from traditional medicinal plants have been reported to have chemopreventive properties. In the present study, therapeutic efficacy of an aqueous extract of Indigofera aspalathoides against growth of transplanted experimental fibrosarcomas in Wistar strain male albino rats was tested. Tumors which appeared about six weeks after implantation were highly localized and were maintained by serial transplantation. Rats were divided into four groups. Group I served as normal control animals. Group II were fibrosarcoma bearing animals. Group III were animals with fibrosarcoma treated with Indigofera aspalathoides aqueous extracts at a dose of 250 mg/kg. b. w. per day for 30 days. Group IV animals were treated with aqueous extract of Indigofera aspalathoides alone. Reduction in tumor weight was noted in Group III as compared to II. The levels of cytochrome C in liver and kidney, the levels of cytochrome P450 and cytochrome b5 in liver microsomes, phase I biotransformation enzymes NADPH-cytochrome P450, NADPH-cytochrome b5, and aniline hydroxylase, and the phase II enzymes glutathione-S-transferase and UDP glucuronyl transferase indicated that their modulation played a role in the therapeutic efficacy of Indigofera aspalathoides against experimental fibrosarcoma.

Methanol extract of Indigofera linnaei (MEIL) was investigated for antitumor, cytotoxic and antioxidant activities against transplantable tumors and human cancer cell lines. In vitro cytotoxicity was evaluated in HeLa, Hep-2, HepG-2, MCF-7, HT-29, Vero and NIH 3T3 cells by MTT assay and in vivo antitumor activity with Ehrlich ascites carcinoma (EAC) and Dalton's ascites lymphoma (DLA) tumor-bearing mice. Activity was measured by monitoring the mean survival time, effect on hematological parameters, antioxidant enzyme levels and solid tumor volume. The extract exhibited strong in vitro cytotoxicity against all the tested cancer cell lines, but it was found to be safe with normal cells. MEIL at the dose of 200 and 400 mg/kg, significantly increase the mean survival time (P<0.001), exerted a protective effect on the hemopoietic system, demonstrated in vivo antioxidant activity and significantly reduce solid tumor volume (P<0.01). These results show a significant antitumor and cytotoxic effect of MEIL against EAC, DLA and human cancer cell lines and support the ethnomedical use of Indigofera linnaei. (+info)I'm sorry for any confusion, but "Indigofera" is not a medical term. It is a genus of plants in the family Fabaceae, also known as the pea or legume family. The name "Indigofera" comes from the fact that some species of this plant are used to produce a blue dye called indigo.
While some plants in the Indigofera genus have been used in traditional medicine, there is no widely recognized medical definition specifically associated with Indigofera. If you have any questions related to a specific medical topic or condition, I would be happy to try and help answer those for you.
Neisseriaceae is a family of gram-negative, aerobic bacteria that includes several genera of medically significant organisms. The most well-known members of this family are Neisseria and Kingella, which include species that can cause various infections in humans.
The Neisseria genus includes several important human pathogens, such as N. gonorrhoeae (the causative agent of gonorrhea) and N. meningitidis (a leading cause of bacterial meningitis and sepsis). These organisms are typically found in the mucosal membranes of the respiratory and urogenital tracts.
The Kingella genus includes several species that can cause invasive infections, such as K. kingae (a common cause of bone and joint infections in young children) and K. denitrificans (which has been associated with endocarditis and bacteremia).
Overall, Neisseriaceae is an important family of bacteria that includes several significant human pathogens, many of which can cause serious and potentially life-threatening infections if left untreated.
Aniline hydroxylase is an enzyme that is involved in the metabolism of aromatic compounds, including aniline and other related substances. The enzyme catalyzes the addition of a hydroxyl group (-OH) to the aromatic ring of these compounds, which helps to make them more water-soluble and facilitates their excretion from the body.
Aniline hydroxylase is found in various tissues throughout the body, including the liver, lung, and kidney. It is a member of the cytochrome P450 family of enzymes, which are known for their role in drug metabolism and other xenobiotic-metabolizing reactions.
It's important to note that exposure to aniline and its derivatives can be harmful and may cause various health effects, including damage to the liver and other organs. Therefore, it is essential to handle these substances with care and follow appropriate safety precautions.
"Pseudomonas" is a genus of Gram-negative, rod-shaped bacteria that are widely found in soil, water, and plants. Some species of Pseudomonas can cause disease in animals and humans, with P. aeruginosa being the most clinically relevant as it's an opportunistic pathogen capable of causing various types of infections, particularly in individuals with weakened immune systems.
P. aeruginosa is known for its remarkable ability to resist many antibiotics and disinfectants, making infections caused by this bacterium difficult to treat. It can cause a range of healthcare-associated infections, such as pneumonia, bloodstream infections, urinary tract infections, and surgical site infections. In addition, it can also cause external ear infections and eye infections.
Prompt identification and appropriate antimicrobial therapy are crucial for managing Pseudomonas infections, although the increasing antibiotic resistance poses a significant challenge in treatment.
