The present study provides the information about medicinal plants in Garhwal Himalaya, Uttarakhand, India. The objective of the study was to document the available important medicinal plant species and their use in several different health issues of rural people. Numerous ethnomedicinal surveys were conducted in the villages of Chamoli, Pauri and Rudraprayag districts during 2014. Data on different aspects of medicinal plants were collected by interviewing the local communities, following a simple random sampling method with at least 5 % sampling from each village. During survey, a total of 66 important plant species were recorded, from most of which roots (40 %) are used. Maximum number of species was recorded from the family Asteraceae (5 species). In present study area, due to over exploitation and unsustainable harvesting, several important commercial medicinal plants are facing great threats and need to be conserved properly. Moreover, lack in interest of present generation about the use of medicinal plants augments the threat. Therefore, suitable conservation planning is strongly recommended to conserve medicinal plants including biomedical research, transfer of technology to harvest the existing medicinal plants sustainably, organization of educational and awareness programmes among local communities.

Expert Opinion on Drug Delivery | Year: 2014
Introduction: Poor solubility and dissolution of drugs are the major challenges in drug formulation and delivery. In order to improve the solubility and dissolution profile of drugs, various methods have been investigated so far. The cyclodextrin (CD) complexation and phospholipid (PL) complexation are among the exhaustively investigated methods employed for more precise improvement of the solubility and dissolution of poorly water-soluble drugs.Areas covered: The article discusses the CD and PL complexation techniques of solubility and dissolution enhancement. Various studies reporting the CD and PL complexation as the potential approaches to improve the dissolution, absorption and the bioavailability of the drugs have been discussed. The article critically reviews the physicochemical properties of CDs and PLs, eligibility of drugs for both the complexation, thermodynamics of complexation, methods of preparation, characterization, advantages, limitation and the meta-analysis of some studies for both the techniques.Expert opinion: The CD and PL complexation techniques are very useful in improving solubility and dissolution (and hence the bioavailability) of biopharmaceutical classification system Class II and Class IV drugs. The selection of a particular kind of complexation can be made on the basis of eligibility criteria (of drugs) for the individual techniques, cost, stability and effectiveness of the complexes. © 2014 Informa UK, Ltd.

Ethnopharmacological relevance: Inspite of tremendous advances made in allopathic medical practices, herbs still play an important role in the management of various liver diseases. A large number of plants and formulations have been claimed to have hepatoprotective activity. Jaundice is a symptom, indicative of the malfunctioning of the liver. This paper provides ethnomedicinal information on the plants used to treat jaundice by three important indigenous communities, i.e.; nomadic Gujjars, Tharu and Bhoxa of Sub-Himalayan region, Uttarakhand, India. Aims of the study: To record herbal preparations used by the studied indigenous communities in treatment of jaundice and discuss hepatoprotective properties of the recorded plants. Research strategy and methods: The traditional knowledge of the studied indigenous communities on herbal preparations used for treating jaundice was collected through structured questionnaire and personal interviews. The interviews were conducted with 91 traditional healers (29 Bhoxa, 35 Tharu and 27 nomadic Gujjars) in Sub-Himalayan region of Uttarakhand, India. More than 250 research papers reporting ethnomedicinal information on the hepatoprotective plants used by various communities from different parts of India were extensively reviewed. Results: A total of 40 medicinal plants belonging to 31 families and 38 genera were recorded to be used by the studied communities in 45 formulations as a remedy of jaundice. Bhoxa, nomadic Gujjars and Tharu communities used 15, 23 and 9 plants, respectively. To our knowledge eight plants reported in the present survey viz.; Amaranthus spinosus L.; Cissampelos pareira L.; Ehretia laevis Roxb.; Holarrhena pubescens Wall.; Ocimum americanum L.; Physalis divaricata D. Don, Solanum incanum L. and Trichosanthes cucumerina L. have not been reported earlier as remedy of jaundice in India. Literature review revealed that a total of 214 (belonging to 181 genus and 78 families), 19 (belonging to 18 genus and 12 families) and 14 (belonging to 14 genus and 11 families) plant species are used as internal, external and magico-religious remedies for jaundice, respectively by various communities in different parts of India. Most widely used hepatoprotective plant species for treatment of jaundice in India is Boerhavia diffusa L. followed by Tinospora cordifolia (Willd.) Miers, Saccharum officinarum L.; Phyllanthus amarus Schumach. & Thonn.; Ricinus communis L.; Andrographis paniculata (Burm. f.) Nees.; Oroxylum indicum (L.) Kurz, Lawsonia inermis L. and Eclipta prostrata (L.) L. Conclusions: The plants recorded in the present survey have also been discussed in relation to pharmacological studies and hepatoprotective phytoconstituents present in them. Most of the recorded plants have shown hepatoprotective effects on experimental animals in earlier studies but more studies are needed to assess hepatoprotective properties of some recorded medicinal plants viz.; Averrhoa carambola L.; Ehretia laevis Roxb.; Holarrhena pubescens Wall.; Mangifera indica L.; Ocimum americanum L.; Oroxylum indicum (L.) Kurz, Physalis divaricata D. Don, Solanum incanum L.; Sphaeranthus senegalensis DC. and Tribulus terrestris L. The plants enumerated in this study with high number of citations and wider distributions have given some useful leads for further biomedical research. Nevertheless more phytochemical, pharmaceutical and clinical studies are needed to evaluate hepatoprotective properties, efficacy and safety of all the claimed medicinal plants. © 2012 Elsevier Ireland Ltd.

Hedychium spicatum Smith is a medicinally important species of the genus Hedychium commonly known as Vanhaldi, Palashi and Kapurkachari. This species occurs in subtropical and temperate Himalayan region between 1500 m and 2700 m altitudes. In the present study MS media supplemented with different growth regulators such as Kinetin and IAA were used for shoot elongation and root formation from in vitro shoot tip. Shoot elongation and rooting percentage (80%) was reported highest on medium with 5.0mM/l Kn and 1.0mM/l IAA. After rooting the complete plantlets were transferred to sterilized soil pots for acclimatization. About 40-50% plantlets survived well.

Organochlorine pesticides, dichlorodiphenyltrichloroethane (DDT) and hexachlorocyclohexane (HCH), are potential chemical pollutants extensively used for agriculture and vector control purposes due to low cost and high effectiveness. Concentrations of HCH and DDT were determined in 175 surface soil samples from different agricultural fields, fallow and urban lands of districts Nagaon and Dibrugarh, Assam, India. The mean concentrations of total HCH and total DDT were 825. ng/g (range: 98-1945. ng/g) and 903. ng/g (range: 166-2288. ng/g) in district Nagaon while 705. ng/g (range: 178-1701. ng/g) and 757. ng/g (range: 75-2296. ng/g) in district Dibrugarh, respectively. The soils from paddy fields contained highest amounts of HCH and DDT residues. Total organic carbon was found to be positively associated with soil HCH and DDT residues. Ratios of DDT/(DDD+DDE) were 1.25 and 1.82 while of α/γ HCH were 2.78 and 2.51 for districts Dibrugarh and Nagaon, respectively. Source identification revealed that soil residue levels have originated from long past and recent mixed source of technical HCH and Lindane for HCHs and mainly technical DDT for DDTs. Spatial distribution was also investigated to identify the areas with higher pesticide loadings in soil. © 2011 Elsevier Inc.

Mahseer species, the national heritage of India are globally acclaimed sport and table fish. Some mahseer species are now assessed as 'endangered', making it imperative to review historical and current state of knowledge on sport-related facets, taxonomy, fisheries ecology, biology, culture and conservation efforts. The review also examines the shortfalls in knowledge base and suggests issues that need to be addressed in future. The protection and conservation measures have fallen short of expectations as the pace of implementing mega-developmental projects exceeds natural recruitment rate of mahseers and lack of facilities for assisted propagation, at larger scale. © 2013 The National Academy of Sciences, India.

Despite the worldwide ban on use of persistent organochlorine pesticides, their usage continued until recently in India, for vector-borne disease eradication programs and agricultural purposes. The concentrations of organochlorine contaminants, DDT and HCH, have been determined in human breast milk from Dibrugarh and Nagaon districts of Assam state, North-East India. The results demonstrated that the mean levels of total DDT were 3210 ng/g lipid wt. and 2870 ng/g lipid wt. and total HCH were 2720 ng/g lipid wt. and 2330 ng/g lipid wt. in Nagaon and Dibrugarh respectively. There was no significant difference in the levels of investigated pollutants between the two districts. Significant differences in ADI (Average daily intake) for total DDT were found between the two districts. In addition, a positive correlation was observed between OCP levels in breast milk and age of mothers. Based on OCP levels in human breast milk, the ADI by the infants has been estimated. It has been found that high daily intake of DDTs and HCHs by the infants exceeded the TDI (Tolerable daily intake) which implied that infants of the region are potentially at high risk by these contaminants. © 2011 Elsevier B.V.

Measurements of radon, thoron and their progeny were carried out in some houses from Garhwal and Kumaun Himalayas of India using a LR-115 plastic track detector. The measurements were made in various residential houses of the area at a height of 2.5 m above the ground level using a twin chamber radon dosemeter, which can record the values of radon, thoron and their progeny separately. The concentrations of radon and thoron in these homes were found to vary from 11 to 191 and 1 to 156 Bq m-3, respectively. The equilibrium factor between radon and progeny varies from 0.02 to 0.90, with an average of 0.26 for the region. The resulting dose rate due to radon, thoron and their decay products was found to vary from 0.02 to 0.84 μSv h-1 with an arithmetic mean of 0.27 μSv h-1. A detailed analysis of the distribution of radon, thoron and their decay products inside a house is also reported. The observed dose rates due to radon, thoron and progeny were found somewhat higher but well below the international recommendations. © The Author 2011. Published by Oxford University Press.

The variations of spring water radon concentration and meteorological parameters were analysed in relation to the seismic activities in Garhwal Himalaya, India. The radon anomalies were classified on the basis of statistical treatment of the daily observations. The precise measurements of water discharge rate from the spring have been made along with radon measurements for earthquake precursory study. The earthquakes with epicentral distances less than 150 km were considered by an empirical relationship. Pre-, co-, and post-seismic changes in the radon concentration were taken carefully into account in the empirical relationship to establish this behaviour as a potential earthquake precursor. The empirical relationship has been validated by the radon data recorded from the spring waters. The magnitudes of the earthquakes were estimated by using the empirical relationship by introducing computed correlation coefficient of radon and meteorological parameters. The calculated magnitude of some local earthquakes matches exactly with the magnitude recorded by the laboratory seismograph. The possible mechanisms that may cause a radon anomaly are also discussed. © 2009 Versita Warsaw and Springer-Verlag Berlin Heidelberg.
