The study was conducted to investigate the in vitro anti-glycation activity of Phyllanthus amarus plant extract. The above plant has been used for centuries for its useful health benefits in variety of inflammatory diseases. In current study, antioxidant, metal chelating and ferric ion reducing and antiglycation property was studied for the polysaccharides isolated from Phyllanthus amarus plant extract. At 25 μg/mL sugar concentration and Vitamin C, gave 57 % and 65 % inhibition in hydroxyl radical scavenging assay and in Antiglycation assay the extract and vitamin C showed 65% and 87% respectively. It also had metal ion chelating (PAPE 74%, Ascorbic acid 88%) and ferric ion reducing activity showed by PAPE IS about 68% when compared to standard metal ion chelator EDTA 90%. It inhibited fructosamine formation by 52% after 3 days of incubation. The above studies gave an opinion that the inhibition of glycation exhibited by extract was due to its free radical scavenging property but also due to the modification in the amino or carbonyl groups resulted in the inhibition of fructosamine formation. The polysaccharides of the extract may be donating the hydrogen atom to the free radical, and exhibiting the antioxidant activity. So polysaccharide isolated from Phyllanthus amarus plant may use in preventing many free radicals induced diseases and also in delaying or preventing complications of diabetes.

Bioenhancers are drug facilitator which do not show the typical drug activity but in combination to enhance the activity of other molecule in several way including increase the bioavailability of drug across the membrane, potentiating the drug molecules by conformational interaction, acting as receptor for drug molecules and making target cell more receptive to drugs and promote and increase the bioactivity or bioavailability or the uptake of drugs in combination therapy. The objective of the present study was to evaluate the antibacterial and activity of combination in Azadirachta indica extract with cow urine distillate and pepper extract against common pathogenic bacteria, a causative agent of watery diarrhea. It has been found that Indian indigenous cow urine and its distillate also possess bioenhancing ability. Bioenhancing role of cow urine distillate (CUD) and pepper extract was investigated on antibacterial activity of ethanol extract of Azadirachta indica. Antibacterial activity of ethanol extract neem alone and in combination with CUD and pepper extract were determined the ATCC strains against Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa and E-coli by cup plate diffusion method. Ethanol extract of neem has showed more effect on P. aeruginosa, E-coli than S. aureus and K. pneumonia with combination of CUD and pepper extract. CUD and pepper did not show any inhibition of test bacteria in low concentration. The antibacterial effect of combination of extract and CUD was higher than the inhibition caused by extract alone and is suggestive of the bioenhancing role of cow urine distillate and pepper. Moreover, inhibition of test bacteria was observed with less concentration of extract on combining with CUD

Silver nanoparticles (NP) offer many applications in the science and technology. Oral delivery of such tiny particles results in enhanced drug absorption, reduction in dose, and minimize adverse effects. This review focuses on the mainly on the effects in the gastrointestinal tract along with its in vitro and in vivo studies carried on the silver NP. In this review, we compiled some of the extensive research in the field of silver NP, highlighting some of the most recent trends in the area. Search was carried in English language using Science direct, PubMed, and Google scholar search engines. The effects of silver NP on gastrointestinal tract such as absorption, distribution, metabolism, and elimination were compiled in this review. In addition, selected in vitro and in vivo studies related to the same are discussed. The accumulation of silver NP leading to Arginia condition also emphasized in the study. Silver NP and herbal silver NP in oral delivery can be exploited for the further safer and effective treatment.

The study was done to investigate the in vitro anti-diabetic activity of Ethanol-water extract of Abutilon indicum plant leaves. The phytochemicals present in the extract was analyzed by using standard methods. In vitro antioxidant study was done using DPPH radical scavenging activity. The In vitro anti-diabetic studies were done by alpha amylase enzyme, alpha glucosidases enzyme inhibition studies and Glucose uptake in Yeast cells studies. The phytochemical analysis showed that the extract rich with proteins, polyphenols, flavonoids, alkaloids, tannins, polysaccharides. The in vitro antiglycation potential of extract was confirmed through alpha amylase enzyme, alpha glucosidases enzyme inhibition studies and Glucose uptake in Yeast cells studies. The results of the present study showed the significant antioxidant and antidiabetic activity. The potential pharmacological activity of Abutilon indicum might be the presence of phytochemicals.

The main objective of ocular drug delivery is to improve the currently available conventional dosage form and exploit newer drug delivery system, with the view to improve their therapeutic efficiency. Topical application of eye drops is quite common among the patients suffered from the eye diseases. Commonly used conventional eye drops shows low ocular bioavailability due to constant lachrymal secretion, tear turnover, blinking, reflex and rapid nasolachrymal drainage. Normal drainage of an instilled dose commences immediately on instillation and is essentially completed within 5 min (Achouri et al., 2013). Typically less than 5% of ocular bioavailability is achieved for eye drops due to the short precorneal residence times. Consequently, there is a need for frequent instillation of concentrated solutions to achieve the desired therapeutic effect. To overcome these problems various ophthalmic formulations, such as viscous solutions, ointments, gels, nanoparticles or polymeric inserts have been investigated (Patel et al., 2013). The corneal contact time has been increased to varying degrees by these vehicles. But, they have not been unanimously accepted, because of blurred vision (e.g. ointments) or lack of patient compliance (e.g. inserts). As a result, good ocular bioavailability following topical delivery of a drug to the eye remains a challenge and yet to be resolved (Li et al., 2010). In order to improve ocular bioavailability many research on drug reservoir system have been made. These reservoir systems are carrier of drug molecules and the controller of the drug release pattern. Cubosome is recently developed drug reservoir system and successfully used for ocular drug
