The mineral Srotonjana (antimony sulfide) is being used by Indians since ancient times. In Ayurvedic texts, it has been directed that Srotonjana should be used only after shodhana. Shodhana is a process to remove the unwanted physical, chemical impurities and toxic material and makes it suitable for medicinal use. Metallography is an advanced scientific study which is used in the study of the microstructure and identification of the parent metal particles along with the nature of compound formed during the shodhana. The difficulty of low solubility and less dissolution rate of metal and minerals has received broad academic and industrial awareness. So the aim of present study was to generate metallographic and solubility in the different solvent study as a tool (fingerprint) for ashodhita and shodhita Srotonjana for quality assessment and standardization. In the present study, Srotonjana was shodhit by seven bhavana (levigation) with bhringraj swaras and with triphala kwath. The finding results revealed that after shodhana Srotonjana broke into smaller particles and became homogeneous in both shodhit the...

Helminthiasis is also known as worm infection and a endoparasitic disease of humans and other animals in which a part of a body is infected with parasitic worms. Tinospora cordifolia is a well known medicinal plant and widely used in folk medicine ayurvedic system. The objective of this work is to carry out phytochemical screening and in vitro anthelmintic activity of methanolic, petroleum ether and ethylene glycol extracts of leaves of Tinospora cordifolia (Menispermaceae) against Indian earthworm, Pheretima posthuma. Various concentrations (2.5, 5, 10, 20 mg/ml) of the extracts were tested, which involved determination of time of paralysis and time of death of the worms using Albendazole (10 mg/ml) as standard drug and normal saline as control. The methanolic extract exhibited a maximum anthelmintic activity than the other two extracts. The extract showed anthelmintic activity in dose dependant manner giving shortest time of paralysis (P) and death (D) with 20mg/ml concentration and caused paralysis in 4 min and death in 10 min respectively. The Preliminary phytochemical analysis indicated the...

Cefepime is a broad – spectrum new parenteral cephalosporin used to treat moderate to severe nosocomial pneumonia, empirical treatment of febrile neutropenia and infections of the skin and urinary tract. In this present study a simple, accurate and precise reverse phase high performance liquid chromatographic method was developed and validated for analysis of cefepime powder for injectable solutions along with its potency by using microbiological bioassay by four different microorganisms. A YMC C 18 (4.6 × 150 mm, 5.0 mm) column was used for cefepime separation, using isocratic elution with acetonitrile: water (70:30, v/v) and UV detection at 235 nm. Microbiological assay (bioassay) was performed using the agar diffusion method. The validation performed yielded good results in terms of linearity, precision, accuracy, and robustness. The retention time obtained for cefepime was 1.77 min and % potency of the marketed dosage form was found to be 147.9%, 100%, 83.17% and 125.8%...

The objective of this work was improvement in the ocular bioavailability of diclofenac sodium by enhancing drug permeation across cornea and promoting drug retention time on ocular surface. Using pseudo ternary phase diagrams transparent regions were identified and nanoemulsions were prepared by self-emulsification method, which were further optimized by emulsification study and drug content. Three best NE formulations were incorporated in 20% poloxamer 407 (thermosensitive polymer solution) to formulate nanoemulsion embedded thermosensitive in-situ ocular gel and further evaluated on the basis of gelation temperature and drug entrapment. Optimized nanoemulsion formulation was evaluated by TEM, particle size analysis and zeta potential. The optimized NE gel formulation changed from sol-gel phase at physiological temperature. Comparison of dissolution profile of developed formulation was carried out with the marketed formulation. The formulated NE in-situ gel showed drug release for a longer duration of time as compared to the marketed eye drops (0.1% w/v Voltaren Ophtha). The in-vitro release data was fitted to various kinetic models. It was found that the in-vitro drug release...

Anti-diabetic and protective activity of T. dioica aqueous extract in diabetic complications in streptozotocin (STZ)-induced diabetic rats was evaluated. Albino rats (n = 24) were divided into four groups, of six animals each. Group 1 (normal control) and Group 2 (diabetic control) received normal saline (10 ml/kg/day p.o.) whereas Group 3 (Standard, insulin 6 U/kg/day s.c) and Group 4 received 1000 mg/kg/day p.o. of T. dioica extract for 28 days. Extract treated animals showed significant decrease in various biochemical parameters like blood glucose, SGOT, SGPT, creatinine, urea, LDL, Cholesterol and glycated hemoglobin. Extract was also effective in diabetic complications like neuropathy and learning and memory dysfunction evaluated by behavioral models like elevated plus maze, object recognition, open field test, rotarod, hot plate, tail flick, immersion in hot and cold water etc. It can be concluded that T. dioica possess significant anti-diabetic and protective activity in diabetic complications in STZ-induced diabetic...
