Herbal medicines are gaining more and more attention all over the world due to their long historical clinical practice and less side effects. The major limitation with herbal medicines is that the lack of standardization technique. Initially, the crude drugs were identified by comparison only with the standard description available.Standardization of drugs means confirmation of its identity and determination of its quality and purity. The quality control standards of various medicinal plants, used in indigenous system of medicine, are significant nowadays in view of commercialization of formulations based on medicinal plants. The quality of herbal drugs is the sum of all factors, which contribute directly or indirectly to the safety, effectiveness, and acceptability of the product. Lack of quality control can affect the efficacy and safety of drugs that may lead to health problems in the consumers. Standardization of drugs is needed to overcome the problems of adulteration and is most developing field of research now. Therefore, there is an urgent need of standardized drugs having consistent quality.The drug showed the presence of phyto-chemical constituents. Powdered drug was treated with different reagents and examined under UV light. Different reagents showed different colors of the drug at 2 wavelengths. The percentage of physiological active compounds viz. total phenolics, tannins, volatile oil, fixed oil, and alkaloids were also observed.Myrtus communis L. (Family: Myrtaceae) is one of the important drug being used in Unani system of medicine for various therapeutic purposes. In this study, an attempt has been made to study berries of M. communis from physico-chemical and phytochemical standardization point of view.

Drug Information Center (DIC) is an information center which provides drug information (DI) to healthcare professionals. The aim was to evaluate the performance of DIC for improving the quality and quantity of information services provided to the healthcare professionals. The service was provided free of cost to the customers.This descriptive study was conducted for the period of 6 months from February to August 2011 excluding May due to vacation. Customers were asked: how did they find the service provided to them? Was it good, satisfactory, or need improvement? There were written feedback forms to be filled by the customers, including customer satisfaction questions. The official publication of the DIC, RIPER PDIC Bulletin was screened for its types of articles/number of drug news published. The bulletin is circulated for free to the healthcare professionals electronically.A total of 232 queries were obtained during the study period of 6 months. Average number of queried received to the DIC was 39 per month. Most preferred mode of queries was personal access (89%). Majority of queries were received from nurses, i.e., 162 (70%) queries and 81% of all queries were drug oriented for improving knowledge. There were only 19% of the queries for individual patients; doctors asked most of those queries. Only 3% queries answered were rated as need improvement by the healthcare professionals. Rest were considered as either Good (56%) or satisfactory (49%). Range of drug news published in each bulletin was 3-4 and most of the other articles include expert opinion to improve practice or training.The DI services were satisfactorily used for academic interests. Nurses used the service for the highest compared to other health care professionals. Future studies should plan to establish the usefulness of DI to improve healthcare practice.

Radiolabeled human Immunoglobulin-G (hIgG) has demonstrated its utility in inflammation and infection imaging. However, the present method of radiolabeling hIgG is time-consuming and complex.To develop a simplified method of radiolabeling hIgG with technetium-99m ((99m)Tc) via a nicotinyl hydrazine derivative ((99m)Tc-HYNIC-hIgG) and its biological evaluation.In vitro and in vivo studies showed that (99m)Tc-hIgG prepared by this method was fairly stable in physiological saline and human serum till 24 h. Only 4.3% degradation of the radiolabeled drug was seen till 24 h. Blood clearance pattern of the radiopharmaceutical exhibited biphasic exponential pattern. Biodistribution of (99m)Tc-HYNIC-hIgG in mice was observed up to 24 h. Significant accumulation of the radiotracer was found in liver (4.93 %), kidney (3.67%) and intestine (2.12 %) at 4 h interval by 24 h interval, it was reduced to 1.99%, 2.18% and 1.93 % respectively. Significant amount of radioactivity in liver, kidney and intestine suggest hepatobilliary as well as renal route of clearance for (99m)Tc-HYNIC-hIgG. The anterior whole body and spot scintigraphy images showed increased uptake of 99mTc-HYNIC-hIgG, with the area seen as a focal hot spot, indicating good localization of the radiolabeled hIgG at the site of infection.The present findings indicate that (99m)Tc-HYNIC-hIgG holds great potential for the scintigraphy localization of inflammation. The shelf life of the developed kit, when stored at (-) 20°C was found to be at least 3 months.
