Sri Rekha Vudara, Prasanna Krishna Vedagiri
Ischemia/Reperfusion (I/R) injury is one of the leading causes of acute kidney injury (AKI) which affects millions of people worldwide. I/R injury mainly occur after infraction, sepsis, and organ transplantation. The present study was conducted to evaluate the prophylactic effect of an ancient medicinal plant, Eclipta alba against experimentally induced bilateral renal I/R injury in rats. 15 male Sprague-Dawley rats were randomized into four groups which include control and two treatment groups which were treated with whole plant methanolic extract of Eclipta alba at graduated doses of 200 and 400 mg/kg/day through oral intubation for a period of 7 days. All the animals were subjected to ischemia for period of 45-min followed by 6 hours of reperfusion. At the end of reperfusion period, pathological alterations in kidney were evaluated by haematological and biochemical analysis in addition to the microscopical examination of kidney. Renal markers such as creatinine and blood urea nitrogen (BUN) were significantly decreased dose dependently in treatment groups when compared to control. Furthermore, there is an up regulation of haematological parameters such as Red blood cell count (RBC), White blood cell count (WBC) and Platelet count. Histopathology examination of I/R control group revealed severe haemorrhages and infract characterized by tubular degeneration, glomerular tuft retraction, thickening of glomerular basement membrane and there is marked endothelial swelling in all parts of cortex and medulla. Whereas, treatment with Eclipta alba at graded doses ameliorated the pathological effects of ischemic insult and there is a marked improvement in the integrity of the anatomical structure of the kidney, thereby, establishing the potential protective effect of the extract against the ischemia – reperfusion injury.

Boswellia dalzielii, the West African species of the frankincense tree, has several applications in ethnomedicine in the sub-region. The present work aims at evaluating the antioxidant and antiproliferative activities of Boswellia dalzielii stem bark. Antioxidant activity was evaluated through DPPH radical scavenging and ferric reducing antioxidant power (FRAP), which often correlates well with total phenolic and flavonoid contents. Antiproliferative activity was evaluated through growth inhibitory effects on Sorghum bicolor seeds. The dried, powdered stem bark of B. dalzielii was extracted with 70% methanol, yielding the crude extract that was partitioned successively into hexane and ethyl acetate; thereafter the aqueous mother liquor was also recovered. The ethyl acetate fraction, being most active in the bioassays, was subjected to Accelerated Gradient Chromatography (AGC) to give four sub-fractions (A-D). Phenolic content was found to be highest in sub-fraction C (481.20 ± 10.13 mg GAE/g) while flavonoid content was highest in methanolic extract (142.17 ± 4.82 mg RE/g). High antioxidant activities were recorded in the aqueous (IC50 1.58) and methanol extracts (IC50 1.99) using DPPH. FRAP assay gave high antioxidant capacity for aqueous extract (EC50 1.00) and sub-fraction D (EC50 1.25). In antiproliferative assay, sub-fractions C and D at 125 µg/ml gave the highest percentage inhibition (90%) followed by sub-fraction B (50%) at 250 µg/ml. These results show that the stem bark of Boswellia dalzielii has strong antioxidant and antiproliferative activities; justifying its application in ethnomedical practice and as a source of bioactive agents with potential to yield anticancer drug candidates.

Patil T R, Patil S T, Patil S, Patil A
Diabetes mellitus is a worldwide fast growing non infectious, metabolic disorder. Hyperglycemia of this disease favors various infections. The choice of non antibiotic, antidiabetic drug metformin to treat diabetes mellitus which has antimicrobial activity was found to decrease the incidence and the severity of infections resulting in to improved outcome. It was found that metformin has antimicrobial activity against many Gram positive and Gram negative bacteria, parasites, fungi and viruses. The most promising antimicrobial activity was found against mycobacterium tuberculosis. The possible mechanisms for this anti tubercular activity of metformin are activation of  AMPK and mitochondrial ROS production, acceleration of phagosome-lysosome fusion, improved immune response, increased CD 4 and CD 8 cells, rise in mycobacteria specific interferon secretion by CD 8 cells, reduced expression of inflammatory genes. Patients of diabetes mellitus with tuberculosis who received anti tubercular treatment along with metformin as an antidiabetic drug had better prognostic outcome than the similar group of patients who did not receive metformin. Metformin was also observed to increase survival in mice having endotoxemia  as a result  of the inhibition of mediators of the inflammation. Thus metformin was found to have promising antimicrobial activity which needs to be confirmed by meticulously planned human studies.
