ABSTRACT
Drug resistance in bacteria is becoming an alarming problem in recent years. Post-antibiotic era is not so far. The need for novel antibiotics, chemotherapeutic agents and agrochemicals are utmost. Endophytes are microorganisms that reside in the tissues of living plants which are relatively unstudied and are potential sources of novel natural products for exploitation in medicine, agriculture and industry. The endophytes of medicinal plants participate in biochemical pathways and produce novel bioactive compounds. The aim of the study was to isolate, identify and to assess antibacterial activity of endophytic bacteria from leaves of Acacia catechu. 18 endophytic bacteria had been isolated and identified by sequencing 16S rRNA gene. The isolated endophytic bacteria were identified as Bacillus humi. Considerable in vitro antibacterial activities against a panel of human pathogenic microorganisms (Staphylococcus aureus, Streptococcus pyogenes, Bacillus cereus, Klebsiella pneumoniae, Salmonella Typhimurium and Escherichia coli) were recorded. Among 18 isolates, 15 isolates had shown inhibitory activity against Staphylococcus aureus and Salmonella Typhimurium and 10 isolates had shown inhibitory activity against Klebsiella pneumoniae
ABSTRACT
ABSTRACT Background Post-operative pain is the major consequence of Ksarasutra, Seton technique employed in Ayurvedic management of Low anal fistula. Surgeons are forced to prescribe Opioids and NSAIDs with pronounced untoward effects. Non pharmacological measures like Balneotherapy are used to improve circulation and relieve spasm in contemporary sciences. Aim To compare the efficacy of Khadira (Acacia catechu) and Sphatika (Potash alum) hot sitzbath with plain hot sitzbath in patients of low anal fistula treated with Ksarasutra. Method The study was single blind, double armed; prospective, randomized control clinical trial in which 30 patients were randomly allocated into two groups of 15 each on the basis of inclusion and exclusion criteria. Group A received hot sitzbath using Acacia catechu and alum infusion twice daily for 21 days. Group B received hot sitzbath using warm water for 21 days. The assessments were made on pain, post-surgical satisfaction burning sensation, tenderness, discharge, constipation, itching and incontinence. Result The disease was prevalent in the 4th decade of life, more in males (86.67%) involved in sedentary work (53.33%) residing in urban domicile, consuming mixed diet (100%). Both groups showed statistically significant improvement in outcome measures like pain, burning sensation, tenderness, discharge, constipation and itching. Conclusion On comparative analysis Acacia and Alum hot sitzbath was more effective in outcomes like pain, surgical satisfaction, burning sensation and discharge. There was no difference in the effect of both interventions with respect to outcome measures like constipation, itching and incontinence.

ABSTRACT
Background: Acacia catechu has been widely used in Ayurveda for treating many diseases. Its heartwoodextract is used in asthma, cough, bronchitis, colic, diarrhea, dysentery, boils, skin afflictions, sores and forstomatitis. The decoction of heartwood is used for drinking purpose in southern part of India especiallyin Kerala.Objective: The current study was carried out to evaluate immunomodulatory effects of heartwood extracts of A. catechu in Swiss albino mice.Material and methods: In vivo immunomodulatory activity was analyzed by hemagglutinating antibody(HA) titer, plaque forming cell assay and delayed type hypersensitivity (DTH). In vitro immunomodulatory potential of the extracts was studied using peritoneal macrophages and splenocytes from mice.Effect of extracts on phagocytic activity of macrophages was analyzed by nitroblue tetrazolium (NBT)reduction assay and cellular lysosomal enzyme assay. Anti-inflammatory activity was studied by nitricoxide (NO) assay and production of TNF-a and IL-10.Results: A dose dependent increase in antibody titer was observed with extracts treatment. Treatmentwith extracts produced an enhancement in the number of antibody producing cells in the spleen. DTHreaction was significantly decreased with extracts treatment. An increased phagocytic response wasshown by peritoneal macrophages on treatment with the extracts as evidenced by its effect on NBTreduction and cellular lysosomal enzyme activity. The extracts inhibited the release of pro-inflammatorycytokine TNF-a and the production of NO. IL-10 production was significantly increased after extracttreatment.Conclusion: The results of the present study indicate the immunomodulatory effects of A. catechu extracts on humoral, cell mediated and non-specific immune functions.© 2017 Transdisciplinary University, Bangalore and World Ayurveda Foundation.

ABSTRACT
Background: Impaired and aberrant wound healing imposes a huge financial burden and places an enormous drain in health care resources in the developed world and an insurmountable problem in the developing countries too. In this study, authors have compared the wound healing effect of topical application of Acacia catechu extract with silver sulfadiazine in excisional wound model in guinea pigs.Methods: Twelve guinea pigs were randomly divided into two groups (n=6). The wound healing was observed in excision model. The standard group is treated with silver sulfadiazine (group 1) and the test group with Acacia catechu extract (group 2). The mean wound size expressed in mm2 and the mean percentage of the wound healed was measured on day 0, 4, 8, 12, 16 and 19. Biopsy was done on day 21 for histopathological examination (HPE).Results: Statistical analysis was done by using unpaired t test for between the groups comparison and by using paired t test for within the group comparison. The mean percentage of the wound healed with-in the groups was found to be statistically highly significant (p value <0.001) and in between the groups was found to be statistically non-significant (p value >0.05). A comparable increase in collagen content and granulation tissue was found on HPE in both the groups on day 21.Conclusions: Wound healing effect of the Acacia catechu extract is equal to and comparable with that of silver sulfadiazine.
ABSTRACT
ABSTRACT Oxidative stress, being the main cause of most of the human diseases, has always been the highlight of research worldwide. This stress can be overcome by administration of natural polyphenols. The Acacia catechu Willd. has many refrences available in Ayurveda as important disease curative plant. Its leaves are investigated for ameliorating oxidative stress in present work. Leaves of A. catechu were extracted with 80% methanol to get methanol extract (AME). It was assessed for antioxidant activity using DPPH, ABTS, CUPRAC, ferric ion reducing, superoxide scavenging and peroxyl radical scavenging assays. DNA protective activity was also investigated using plasmid nicking assay. Further, antiproliferative activity was determined using MTT assay in various human cancer cell lines. The quantification of polyphenols was done by UHPLC analysis. Results confirmed that polyphenols of A. catechu were successful in normalizing oxidative stress. AME was found to be most effective in scavenging ABTS radicals while least effective in scavenging ferric ions. UHPLC analysis showed abundance of ellagic acid, rutin and quercetin in AME. Further, AME showed maximum antiproliferative activity against Hep G2 cancer cells. It is concluded that the polyphenols from A. catechu effectively remediates oxidative stress and hence can be used in curing numerous dreadful diseases.

ABSTRACT
The immunomodulatory effect of aqueous extract of Acacia catechu commonly known as Katha or Karangali was studied at two doses of 5 mg/kg and 50 mg/kg orally. The effect was studied in neutrophil adhesion test, mice lethality test, carbon clearance assay, cyclophosphamide induced neutropenia, serum immunoglobulin levels and the heamagglutination test. Acacia catechu extract showed an increase in the neutrophil adhesion to the nylon fibres, produced a significant increase in the phagocytic index and a significant protection against cyclophosphamide induced neutropenia indicating its effect on cell mediated immunity. On the other hand, Acacia catechu extract produced a significant increase in the serum immunoglobulin levels, increase in the haemagglutination titre values and decreased the mortality ratio in mice, suggesting its effect on the humoral arm of the immune system. From the above results, it was concluded that the aqueous extract of Acacia catechu has a significant effect on both cell mediated and humoral immunity.
