A novel, safe, accurate, sensitive and economic Spectrophotometric method was developed by application of mixed hydrotropy using solution containing 45% urea and 5% sodium citrate as hydrotropic solubilizing agent for the quantitative determination of poorly water-soluble budesonide from bulk and tablet dosage form. The solubility of budesonide increases more than 20 times in mixed hydrotropic solution as compared to solubility in distilled water, thus, a mixed hydrotropic solution containing 45% urea and 5% sodium citrate was employed to carry out spectrophotometric analysis precluding use of organic solvents. Budesonide obeyed Lambert Beer’s law in the concentration range of 5 to 30μg/ml (r2= 0.999) in mixed hydrotropic agent with mean recovery was found 98.75±0.63%. The percent concentration in marketed tablet formulation was found 98.56±1.070%. Parameters such as linearity, precision, accuracy, specificity and robustness were studied as reported in the International Conference on Harmonization guidelines. The relative standard deviations for three replicate measurements in five concentrations of samples were always less than 2%. So this method can successfully employ in the routine...

The present study was undertaken to evaluate the in vitro antioxidant activities of hexane, ethyl acetate and methanolic extracts of Holostemma ada kodien root tubers. The above extracts exhibited a dose dependent scavenging activity against DPPH radicals, Superoxide radicals, and Nitric oxide radicals. Further, the MeOH, EtOAC extracts showed relatively higher reducing power compare to that of BHT. TLC of the above extracts using the DPPH as a spraying reagent revealed yellow spots against purple background indicating the presence of potent antioxidant...

There has been considerable interest in the development of novel compounds with anticonvulsant, antidepressant, analgesic, anti-inflammatory, anti platelet, anti malarial, antimicrobial, antimycobacterial, antitumoral, vasodilator, antiviral and antis chistosomiasis activities. Hydrazones possessing an azometine -NHN=CH- proton constitute an important class of compounds for new drug development. Therefore, many researchers have synthesized these compounds as target structures and evaluated their biological activities. These observations have been guiding for the development of new hydrazones that possess varied biological activities....

Lead is a ubiquitous environmental and industrial pollutant that may have its toxic effects on the male. The present experimental animal study was designed to observe the changes in the testis due to excessive use of lead. Developmental effects were monitored in the male offspring of Swiss mice from Postnatal Day (PND) 1 till PND 21. Lead acetate reduced the number of pups per litter, percentage of live offspring, and pups weight. Testicular morphology was severely affected in mice exposed to Lead acetate. Therefore, exposure during gestation and lactation adversely affects the reproductive system of male mice. In present study lead toxicity induced histological alterations in the various components of the testis. It is observed in present investigation that lead acetate given in high dose (640mg/kg/days) caused decreased body weight as compared to control males during developing period of pups. The microscopic examination revealed that lead induced apparent damage and reduction in the number of seminiferous tubules and primordial germ cells. Oral exposure of lead acetate changed the arrangement...

The aim of the present study is to evaluate the effect of methanol extract of aerial part of Momordica Cymbalaria Hook F on acute inflammation and it justifies the traditional use of this plant in the treatment of various types of pains and inflammation was evaluated in Albino rat. The aerial part of Momordica Cymbalaria Hook F extracted with methanol at an oral dose of 100 and 200 mg/kg body weight exhibited significant anti-inflammatory activity when compared with control. The anti-inflammatory activity of methanol extract of Momordica Cymbalaria Hook F. was evaluated by carrageenan-induced paw edema method in Albino rats. In carrageenan-induced paw edema model, Momordica Cymbalaria Hook F at doses of 100 and 200 mg/kg caused significant inhibition of paw edema by 53.11%( p<0.001) and 55.43 (p<0.001) respectively, 4 hours after carrageenan administration It is clearly evident from the study that an methanol extract of Momordica Cymbalaria Hook F exhibit significant anti-inflammatory effect in albino rats. Results of two doses are also comparable with standard drug (Indomethacin). All...
