Need of an Ancient Roots to Modern Medicine in the Treatment of Cancer- A review
No full textThe already available expensive conventional therapies for cancer like chemotherapy and radiotherapy have a number of side effects such as myelosuppression and neurological, cardiac, pulmonary, and renal toxicity, which pose serious harm to the quality of life. Therefore, there is a need to develop treatment options that include more potent and less toxic anticancer drugs as compared to existing drugs. Studies have shown that regular consumption of fruits and vegetables because of phytochemical compounds extracted from them inhibiting the activity of antioxidant and free radicals which in turn showing anti-cancer activities. More recent semi-synthetic analogues of these agents are vinorelbine (VRLB) and vindesine (VDS). These agents are primarily used in combination with other cancer chemotherapeutic drugs for the treatment of a variety of cancers. VLB is used for the treatment of leukaemia, lymphomas, advanced testicular cancer, breast and lung cancers, and Kaposi’s sarcoma, and VCR, in addition to the treatment of lymphomas, also shows efficacy against leukaemia, particularly acute lymphocytic leukaemia in childhood. VRLB has shown activity against non-small-cell lung cancer and advanced breast cancer. Therefore there is need of developing cell cycle-based, mechanism-targeted ancient based modern cancer therapies that emulate the body\u27s natural process in order to stop the growth of cancer cells. This approach can limit the damage to normal cells and the accompanying side effects caused by conventional chemotherapeutic agents. This review focuses on the role of ancient medicine in modern research and anticancer drug development. The current findings and known anticancer agents from natural sources are discussed, and recent therapeutic advances in this field are presented

Assessment of the antibacterial activity of four essential oils and the biobactericide Neco.
No full textThe purpose of this study was to assess in vitro the activity of four essential oils (Cymbopogon citratus, Eucalyptus citriodora, Lippia multiflora, Melaleuca quinquenervia) and the biobactericide Neco® on Gram-positive bacteria. The aromatogram and antibiogram were assessed by the agar well diffusion method and the Muller Hinton disk-agar diffusion method, respectively. Also, the minimum inhibitory concentration and the minimum bactericidal concentration were determined by the microdilution method in liquid medium. The aromatogram showed that the biobactericide Neco® induced the largest inhibition diameters (34.53 ± 11.82 - 43.92 ± 5.38 mm) of all strains combined, followed by the essential oils of Eucalyptus Citriodora (30.01 ± 3.02 - 41.89 ± 1.77 mm) and Lippia multiflora (20.72 ± 4.72 - 37.61 ± 2.80 mm). However, the essential oils of Melaleuca quinquenervia (19.99 ± 3.93 - 26.20 ± 13.27 mm) and Cymbopogon citratus (13.52 ± 3.59 - 29.08 ± 2.35 mm) had the smallest inhibition diameters. Moreover, the comparison of the activities of the aromatogram and antibiogram revealed generally that activities were higher with essential oils than with antibiotics. At the end of this study, the essential oils of Cymbopogon citratus, Eucalyptus citriodora, Lippia multiflora, Melaleuca quinquenervia and the biobactericide Neco® had an antibacterial activity on Gram+ bacteria
Analgesic and acute inflammation properties of the aqueous extract of dried leaves of Paullinia Pinnata (Sapindaceae) Linn
No full textInflammation is frequently associated with pain. Plants continue to be major resources for therapeutic compounds against various diseases including inflammation and pain. Paullinia Pinnata is used to treat several diseases, including rheumatism and abdominal pain. This study was undertaken to assess the analgesic and anti-inflammatory effects of Paullinia Pinnata. The analgesic activity was evaluated by using behaviour pain model in mice. The anti-inflammatory activity was carried out by using carrageenan, dextran, histamine and serotonin induced inflammation in rat. The extract was administered orally at a dose of 200 and 400 mg/kg. The results showed that the extract significantly (P< 0.001) reduced the number of writhing induced by the acid acetic. The aqueous extract reduced significantly (P< 0.001) the paw licking time in formalin model. The effect of the extract (200mg/kg) was significantly (P< 0.001) reduced in the presence of naloxone, during the inflammatory phase. In addition, the extract significantly (P< 0.05) increase latency time at all point time and all doses on nociception induced by hot plate. Concerning inflammation induced by carrageenan and dextran, the extract significantly (P< 0.001) inhibited oedema during the experimental time at the dose of 200 mg/kg. The results suggested that Paullinia pinnata aqueous extract possess analgesic activities which may interfere in both peripheral and central pathway. The anti-inflammatory activities may be mediated by either inhibiting or by blocking the release of vasoactive substances like histamine, serotonin, kinins and prostaglandins. These results justify the traditional use of the plant in the treatment of pain and inflammation

Antimicrobial activity of marine algal extracts
Full text linkTotal, hydrophilic and lipophilic extracts of 21 marine algae species (2 species of Chlorophyta, 11 of Phaeophyceae and 8 of Rhodophyta) collected along the coast of Russian Far East were screened for antimicrobial activities (against Staphylococcus aureus, Escherichia coli and Candida albicans). Among the macroalgal extracts analyzed, 95% were active against at least one of studied microorganisms, while 80% of extracts were active against two or more test strains. Broad-spectrum activity against three studied microorganisms was observed in the 35% of extracts from tested species of marine seaweeds. The results of our survey did not show clear taxonomic trends in the activities of the total extracts and their hydrophilic fractions against the studied microorganisms. Nevertheless, lipophilic red algal extracts had both the highest values and broadest spectrum of bioactivity among all survey algal extracts. More over, lipophilic extracts from red algal exhibited the highest activity against fungus C. albicans among tested algal extracts

Bone regenerative effect of aqueous Cynanchum wilfordii extract in receptor activator of nuclear factor-κB ligand-induced osteoclast differentiation and estrogen deficiency-induced osteoporosis
No full textOsteoporosis increases with age, most frequently in postmenopausal women because of reduced ovarian hormone levels. Furthermore, estrogen deficiency impairs trabecular metaphyseal bone. Although efficacious, long-term hormone replacement therapy (HRT) has estrogen-like side effects including breast and endometrial cancers, and non-hormonal or herbal therapies may be safer alternatives. Therefore, the aim of this study was to investigate the effects of aqueous extracts of Cynanchum wilfordii (CWW) on receptor activator of nuclear factor-κ B (NF-κ B) ligand (RANKL)-induced osteoclast differentiation in vitro and ovariectomy-mediated osteoporosis in vivo. CWW inhibited RANKL-induced osteoclast formation and tartrate-resistant acid phosphatase (TRAP) activity in primary mouse bone marrow-derived cells. We investigated the osteoprotective effect of CWW in an ovariectomized (OVX) Sprague-Dawley rat model treated with vehicle (OVX/vehicle), 17β-estradiol (OVX/E2), or three CWW doses (100, 200, and 400 mg/kg). After a 24-week treatment, the body and uterus weights were not affected except in the OVX/E2 group. Additionally, bone mineral density (BMD) and histological analyses showed that the BMD of the femurs of CWW400-treated rats was significantly higher than that of the OVX/vehicle rats, and comparable to that of the OVX/E2 group rats. Serum levels of bone turnover markers alkaline phosphatase (ALP), osteocalcin, collagen type I C-telopeptide, and TRAP significantly decreased in the CWW400 group. Our results show that compared to the vehicle, CWW had a significant anti-osteoporotic effect in the OVX model. Taken together, CWW exhibited inhibitory effects on osteoclastogenesis in vitro, and we confirmed its in vivo efficacy in the prevention of osteoporosis
