Objective: The persistence of this effort was to frame, evaluate and examine the impact of natural and semi-synthetic polymer in changing the release rates of matrix tablet loaded with diclofenac sodium. Materials and method: Matrix tablets of diclofenac sodium were made-up by varying the concentrations of both natural polymer i.e Guar gum and semi-synthetic polymer i.e HPMC K4M via straight compression method. Optimization of the tablet was completed by taking quantity of Guar gum and HPMC K4M in percentage as self-governing variable and cumulative percent of drug release at 2 hr, 6 hr and 12 hr as faithful variable using design expert Software. Optimized tablet was assessed for various pre and post compression limitations equated with marketed formulation. Drug release kinetics of the optimized tablet was evaluated by various representations of drug release kinetics. Result: The verdict of present investigation evidently designates that by using both natural and semi-synthetic polymer in a same tablet was given a noteworthy sustained release. The dissimilarity with the optimized formulation in software data...

Toxoplasmosis is a parasitic disease with global prevalence that is caused by a unicellular organism called Toxoplasma gondii. Given the high prevalence of the disease in the country, particularly in pregnant women, and severe complications of the disease for the fetus, congenital type, the disease consequences for patients taking medications that suppress the immune system as well as side effects caused by common treatment methods, discovery of new drugs with minimal side effects seems to be necessary. In this study was an attempt to investigate the effect of tylosin on toxoplasma in-vivo environment. 200000 parasites (tachyzoite form) were subcutaneously injected to 60 Balb/C mice that were divided into 6 groups (each consisting of 10 samples). Tylosin with four different concentration levels (10-80 mg/kg) was intraperitoneally injected. One of the groups was tested without injection of medicine and another group was tested with sulfadiazine and the disease process was carefully investigated in these groups. Comparison of treatment groups with the control group and statistical analysis of data showed a significant...

Dental caries is a complex disease which is expressed as an interaction between various factors including the host, agent, substrate and time. The interplay between the dental biofilm and oral microorganisms is an important feature for development of a cariogenic dental plaque. Formation of the biofilm needs to be controlled through regular brushing in order to prevent the development of caries and periodontal diseases. Hence a study was conducted to evaluate and compare in-vivo the effect of two commercially available herbal and non-herbal (fluoridated) toothpastes on salivary bacterial count in 5 – 10 years age children with 3 – 6 decayed teeth. 40 children were randomly allocated into two groups I and II. Group I were provided with Fluoridated (Kidodent) toothpaste and Group II with Herbal (Babool) toothpaste. Participants were scored for plaque index and saliva sample was collected as the baseline score (day 0). After demonstration of brushing technique participants were asked to brush twice daily. The plaque index score and saliva sample was once again collected at...

A simple, accurate and reproducible HPTLC method has been developed for the simultaneous quantification of diosgenin, oleic acid, harmine and kaempferol from the methanolic extract of fruits of plant Tribulus terrestris L. and its marketed formulation. The CAMAG HPTLC systems with winCATS software used for the analysis. Double development with mobile phase Toluene: Ethyl acetate: Formic acid: Glacial acetic acid (2:1:1:0.75 v/v/v/v) on TLC plate silica gel 60 F 254. Detection and quantification of harmine at 366 nm, kaempferol at 270 nm, diosgenin at 201 nm and oleic acid at 580 nm after derivatization with anisaldehyde sulphuric acid reagent. The quantity of harmine was found to be 0.014% and 0.006%, kaempferol was 0.018% and 0.006%, oleic acid was 0.259% and 0.108% and diosgenin was 0.086% and 0.022% in plant and formulation respectively. The developed method was then validated in terms of specificity, linearity, LOD, LOQ, precision and recovery. The validated method was successfully applied for quantification of four components in a formulation containing Tribulus terrestris L....

Plant mucilages have found wide application in food, pharmaceutical and cosmetic industries. Hence, it would be worthwhile to characterise the physical and chemical attributes of mucilages from commonly available plants for their beneficial utilization. Hibiscus rosa-sinensis Linn. (Family Malvaceae), widely grown as an ornamental throughout the tropics and subtropicsis a good source of mucilage. The present study focuses on the extraction of the mucilage from the leaves of Hibiscus rosa-sinensis, its subsequent quantification and physico-chemical characterisation. A protocol was presently standardized for the yield optimization of mucilage from Hibiscus through detection of an appropriate maceration temperature and precipitation solvent. Further analyses revealed ideal pH value, swelling index, flow properties and particle size of Hibiscus mucilage. Moreover, chemical, FTIR spectral and electrokinetic data of Hibiscus mucilage revealed that it can be considered as a suitable blending ingredient in composites with potential industrial...
