Safety and Effectiveness of Liv.52 DS in Patients With Varied Hepatic Disorders: An Open-Label, Multi-centre, Phase IV Study.

Background The hepatoprotective function of polyherbal formulation Liv.52 in chronic liver diseases is well recognized in published literature. The objective of this open-label, phase IV study was to further strengthen and validate its safety and effectiveness using a large patient pool in a real-world scenario and provide scientific data on symptomatic improvement and supportive treatment in liver function with improvement in quality of life. Methods Adult patients of either sex with one or more clinical symptoms like fatigue, nausea, anorexia, abdominal pain or discomfort, muscle cramps, jaundice, or any other signs and symptoms with a history suggestive of mild-to-moderate hepatic disorders like alcoholic liver disease (ALD), non-alcoholic fatty liver disease (NAFLD), drug-induced hepatotoxicity, or hepatitis were treated with two Liv.52 DS tablets (oral) twice daily for 12 weeks. Results Out of the 1000 enrolled patients, 962 (96%) completed the study with the following subgroups ALD: 375 (38.9%), NAFLD: 379 (39.3%), drug-induced hepatotoxicity: 78 (8.1%), hepatitis: 130 (13.5%). The mean age of enrolled patients was 37.7 years, and the majority of them, 785 (78.5%) were men. The common adverse events observed (with >1.5% incidence) in the study were abdominal pain: 26 (2.6%) and headache: 17 (1.7%). Liv.52 showed statistically significant improvement (P<0.0001) in various clinical signs and symptoms in the majority of patients namely, fatigue: 357/723 (49%), anorexia: 485/620 (78.2%), jaundice: 48/52 (92%). Majority of the patients showed significant improvements from baseline to end of 12 weeks in the liver function test parameters namely, aspartate aminotransferase: 633/840 (75.36%), alanine aminotransferase: 592/729 (81.21%), serum bilirubin: 244/347 (70.32%), alkaline phosphatase: 279/355 (78.59%) with P<0.0001 for all parameters. Statistically significant improvement (P<0.005) was also seen in all the components of the chronic liver disease questionnaire (CLDQ) scores from baseline to 12 weeks. Conclusions The study demonstrated that Liv.52 was hepatoprotective and well tolerated in the study population after treatment for 12 weeks. Significant improvements were seen in clinical signs and symptoms, laboratory parameters of liver function, and CLDQ scores from baseline to 12 weeks. No significant or new safety signals emerged from this study.

Survey of the present health & nutritional status of Shompen tribe of Great Nicobar Island.

BACKGROUND OBJECTIVES: Shompens are one of the two mongoloid tribes of Nicobar district. There is little information about their recent health status since the last survey which was conducted in 1998. Hence, a comprehensive health and nutritional survey was conducted in March 2017 to assess the changes. The survey was carried out by a joint team of various organizations including the ICMR-Regional Medical Research Centre and Tribal Welfare and Health Department both located in Port Blair. METHODS: A detailed health and nutrition survey of the Shompen community was planned by deputing a field research team. The survey included demographic data, anthropometric data, clinical examination, screening for the markers of infectious diseases, respiratory pathogens, tuberculosis and haemoglobinopathies. RESULTS: About half of the Shompen adults (both males and females) had a body mass index (BMI) of ≥23. However, Shompen children had a good nutritional status with no child suffering from undernutrition. As per BMI for age, none of the children <5 yr were under-nourished, while in the 5-17 yr group, 12 per cent of children were undernourished. Anaemia prevalence was about 48.3 per cent, with 54 per cent prevalence in females and 43.8 per cent in males. Fungal infection of the skin, acute respiratory infection and abdominal pain were the common morbidities observed. None had active pulmonary tuberculosis. Of 38 Shompens screened for IgG (immunoglobulin G) antibodies, 42.1 and 18.4 per cent were positive for measles and rubella, respectively. Seroprevalence of Leptospira was 35.5 per cent. The prevalence of hypertension was 13.2 per cent, whereas another 28.9 per cent were pre-hypertensive. INTERPRETATION CONCLUSIONS: The population structure of the Shompen is not skewed and under nutrition was not widely prevalent among the children of <5 yr. The other positive observations were the absence of malaria, filariasis and dengue. However, there was natural infection of measles and rubella. Fungal skin infection and intestinal parasitic infestations were widely prevalent. Although cardiovascular risk profile was low, there were signs of emerging risk of over-weight, hypertension and dyslipidaemia. These together with the high prevalence of smokeless tobacco use may have a serious effect on the cardiovascular disease susceptibility of the Shompen population in the future.

In vitro immuno-stimulatory and anticancer activities of Oroxylum indicum (L.) Kurz.: An evidence for substitution of aerial parts for conservation.

BACKGROUND: In Ayurveda, "Dashamoolarishta" is one of the important composite herbal formulations. Mainly, the root and root bark of Oroxylum indicum are used as one of the ingredients in its preparation. This leads to over exploitation of medicinal plants owing, to excessive demand due to population expansion and its perceived importance in traditional herbal remedies. OBJECTIVE: For the conservation of biodiversity, the present investigation had an objective to prepare the extracts of different parts of O. indicum plant and to, compare the chemo-profiles as well as to study the biological activities of the prepared extracts. MATERIALS AND METHODS: Hydro-alcoholic (HA) and aqueous (Aq) extracts of various plant parts were prepared and chemical investigation was done with the help of (LC-MS/MS). Further, in vitro biological activities such as immuno-stimulation (IS) using a cytokine bioassay in RAW264.7 and in vitro anticancer in TNF-α ELISA in THP-1 cells were studied. RESULTS: The mass spectral profile of the plant revealed the presence of markers such as oroxylin A and chrysin in HA and Aq extracts of stem, leaf, bark and root. Cytokine release and TNF-α secretion was observed in both hydro-alcoholic and aqueous extracts. CONCLUSION: Based on the results from the present study, it can be concluded that it is possible to replace the roots and the bark of O. indicum with the stem of young plants and leaves. It paves a way for the conserving the medicinal plants without uprooting and extinguishing the whole plant.

Participants' perception of the AIIMS Trauma Assessment and Management (ATAM) course for management of polytrauma: A multi-institutional experience from India.

BACKGROUND: In India, the mortality due to polytrauma after road traffic injuries is high and there is a need to train medical and paramedical personnel. The AIIMS Trauma Assessment and Management (ATAM) course was developed at the Apex Trauma Centre of All India Institute of Medical Sciences, New Delhi to sensitize medical personnel with initial assessment and management of polytrauma victims. The aim of this study was to evaluate the impact on knowledge and skills and also evaluate the feedback and the perception of the participants of the ATAM course. METHODS: The course was conducted for doctors, nurses and other paramedical/allied professionals in five tertiary level centres associated to medical colleges from geographically diverse locations (Anand, Bengaluru, Delhi, Lucknow and Thrissur). Cognitive knowledge was assessed using pre-training and post-training multiple choice question (MCQ) tests. The participants also self-rated their level of knowledge, skill, confidence and capability (Numerical rating scale of 1-10). Post-training feedback was obtained from the participants using a five-point Likert scale response. RESULTS: 26 ATAM courses were conducted by 68 course instructors and attended by 780 participants. These participants include 40.4% doctors, 44.2% nurses, 4.7% paramedical technicians, 4.2% medical students and 6.4% paramedical and allied health professionals. There was significant improvement (p < 0.0001) in the cognitive knowledge, skill, confidence and capability of the participants. 85%-86% of the participants strongly agreed or agreed that the course content was effective and 85% of participants perceived that the course was excellent or very good. CONCLUSION: The ATAM course had a positive impact on the knowledge, skills, confidence and capability of health caregivers attending the course. The ATAM course is an effective, practical and favourable option that is tailored to the polytrauma training needs of India. We recommend widespread dissemination of this course.

Trauma Care in India: Capacity Assessment Survey From Five Centers.

BACKGROUND: India is in the process of strengthening the trauma care system, and assessment of the current situation using standard guidelines has immense use. This study reports the status of trauma care facilities in India, with a broad framework of guidelines for essential trauma care by the World Health Organization. MATERIALS AND METHODS: This study is part of a multicentric intervention study to standardize structured trauma care services in five Indian cities. Thirty trauma care facilities (five level I, 10 level II, and 15 level III facilities) were included. Data on the availability of equipment and manpower were collected. Availability of knowledge + skills and equipment + supplies was assessed based on the guidelines for essential trauma care by World Health Organization. RESULTS: There is almost 100% availability of services and equipment in level I hospitals, but availability varied between 50% and 100% at level II facilities. Very fewer number of services are available at level III facilities. Inadequacy of equipment is reported in level II and III facilities. Only level I facilities have required human resources. Availability of resources in terms of knowledge and equipment of different skills indicated that overall optimal level is observed in level I hospitals. Level II facilities are more deficient in nursing and paramedic staff, and level III facilities reported deficiencies in all categories. CONCLUSIONS: A significant imbalance between recommended resources and the resources that are available in the trauma care facilities was noted. Hence, the study warrants urgent strengthening of trauma care facilities, particularly of level II and III facilities.

An Interventional Study on Comprehensive Emergency Care and Trauma Registry for Road Traffic Injuries in India: A Protocol.

Road traffic injuries (RTIs) stands as one of the leading causes of mortality and morbidity across the globe. Effective injury surveillance systems and pre-hospital and in-hospital interventions set up in developing countries have shown promising results in controlling the problem. This study aimed to standardise and evaluate an evidence-based intervention for safety, efficacy and quality of post-crash pre-hospital and in-hospital trauma care services to improve the outcome in RTI victims. In addition, it establishes the android-based trauma registry for effective RTI surveillance. This multi-centric, prospective, observational study is commissioned by the Indian Council of Medical Research (ICMR) as a National Task Force Project. This study is being conducted in five sites, viz., Anand, Bengaluru, Delhi, Lucknow and Thrissur located across India. Each centre will have a level I, two level II and three level III trauma hospitals. The study will be carried out in four phases namely: i) preparatory phase, ii) trauma registry establishment and pre-intervention data collection, iii) intervention and iv) impact evaluation. The preparatory phase, which lasts for four months includes the situational analysis pertaining to managing RTIs. Trauma registry will be initiated from the fifth month. Pre-intervention data will be collected for six months. The intervention will be conducted for six months in the form of prehospital notification, training for trauma care providers and trauma care quality improvement. Post-intervention data collection will continue for 12 months and the impact of the intervention will be assessed. The primary outcome measure will be early preventable mortality, defined as death at 24 hours after admission for patients with a calculated probability of survival >50% based on their injury severity score.

Correction: A clinical and computational study on anti-obesity effects of hydroxycitric acid.

[This corrects the article DOI: 10.1039/C9RA01345H.].

A clinical and computational study on anti-obesity effects of hydroxycitric acid.

Hydroxycitric acid (HCA), a major active ingredient of Garcinia cambogia extracts, is known to suppress body weight gain and fat synthesis in animals and humans. But the underlying mechanism of HCA action is not fully understood. Clinical study on 100 obese individuals for a period of 3 months was performed followed by a computational study aimed to investigate the effects of HCA treatment on human subjects at anthropometric and plasma lipid profile levels. A detailed hepatic metabolic model was used to incorporate the effect of HCA at the metabolic pathway level. Perturbation analysis of ATP citrate lyase activity in the metabolic pathway was performed to simulate the net effect of HCA. Significant reductions in body weight, triceps, subscapular, and mid axillary measurements as well as in serum triglyceride, cholesterol, HDL and LDL levels were observed following HCA dosage. During the study, half of the subjects experienced a decline in body weight and the remainder experienced an increase in body weight. However, analysis of fat mass with the help of empirical correlations clearly showed significant reduction in the mean values due to HCA dosage in both cases. An extra increase in fat free mass was responsible for offsetting the decrease in fat mass for the subjects who experienced an increase in body weight during the trials. Perturbation analysis showed a net reduction in fatty acid, triglyceride and cholesterol synthesis along with urea cycle fluxes under lipogenetic conditions. Moreover, protein synthesis fluxes increased under these conditions. These results indicate that HCA treatment can reduce body weight gain and fat accumulation in obese subjects along with improving their anthropometric parameters and metabolic state.

Ketosteroid Standardized Cissus quadrangularis L. Extract and its Anabolic Activity: Time to Look Beyond Ketosteroid?

BACKGROUND: Cissus quadrangularis (CQ) L. reported to contain 3-ketosteroids and have bone health benefits. AIM: This study aimed at establishing the relationship between the ketosteroid content and anabolic as well as bone health-promoting activities of various Cissus extracts in well-established orchidectomized (ORX) rat model. MATERIALS AND METHODS: Supercritical carbon dioxide, ethyl acetate, and aqueous extracts (AE) of CQ L. were prepared and standardized for ketosteroid content by two methods used in commerce. Moreover, ketosteroid standardized extracts of this plant were evaluated for anabolic activity in rats in well-established ORX rat model. RESULTS: The increase in the absolute weight was appreciable in the CQ-AE treated group. Similarly, with respect to bone parameters, a similar trend was seen. The mean bone density, strength, and calcium content were found to be highest in the group treated with CQ-AE compared to groups treated with other extracts. This study reveals for the first time that 3-ketosteroids are not linked to the beneficial activities on bone and highlights the need for extensive characterization of biological active principles from CQ L. CONCLUSION: In light of the above estimation studies, we believe that current standardization of Cissus extraction "3-ketosteroids" is incorrect. We also did not find any report suggesting the presence of androgenic steroids in this plant and hence the characterization based on "3-ketosteroids" is scientifically incorrect. This study highlights the insufficient understanding of biological active principles from CQ L. and underlines the need for extensive bioactivity guided studies. SUMMARY: Cissus quadrangularis (CQ) L. reported to contain 3.ketosteroids and have bone health benefitsWe did not find correlation between ketosteroid content obtained by conventional methods and its biological effectStudies indicate that claims of ketosteroid content need not necessarily correlate to biological effects and hence warrants extensive phytochemical characterization of biological active principles from CQ L. Abbreviations used: CQ: Cissus quadrangularis, ORX: Orchidectomized, AE: Aqueous extract, EE: Ethyl acetate extract, SFE: Supercritical fluid extract.

Anti-skin ageing activity of napthoquinones from Arnebia nobilis Reichb.f.

The present isolation and identification of napthoquinones from roots of Arnebia nobilis Reichb.f. can lead to the discovery of new anti-skin ageing ingredient in colour cosmetics. Four compounds have been isolated and purified by rigorous column chromatography. The compounds are identified as ß, ß-dimethylacryl alkannin (AN-I), acetoxyisovaleryl alkannin (AAN-II), acetyl alkannin (AN-III) and alkannin (AN-IV) by interpretation of spectroscopic data. This study is the first to report the isolation of Acetoxyisovaleryl alkannin (AAN-II) from A. nobilis. The IC50 values of the compounds, determined in human skin cells (human dermal fibroblasts and human keratinocytes) and mouse embryonic fibroblasts (NIH3T3) varied significantly among the four alkannins. Among the four compounds, ß-acetoxyisovaleryl alkannin (AAN-II) significantly inhibited hydrogen peroxide (H2O2)-induced red blood corpuscle haemolysis and cellular senescence in human dermal fibroblasts. Collagen-I, elastin and involucrin syntheses in human dermal fibroblasts or keratinocytes were up regulated by AAN-II. These results support the potential utility of alkannins as novel anti-ageing ingredients.

IM-133N modulates cytokine secretion by RAW264.7 and THP-1 cells.

An indigenous herbal extract IM-133N containing extracts of Prosopis glandulosa Torr and Symplocos racemosa Roxb were evaluated for potential immunomodulatory effects using RAW264.7 and THP-1 cells. The incubation of the cells for 24 h with IM-133N over a dose range 0-125 µg/ml did not cause cytotoxicity that exceeded 10%. The results indicated that non-cytotoxic doses of IM-133N effectively up-regulated iNOS, TNFα, IL-6, IL-10, IL-8 and IFNγ gene expression in both the RAW264.7 and THP-1 cells. The results also indicated IM-133N elicited dose-related increases in nitric oxide (NO) and tumor necrosis factor (TNF)-α production by RAW264.7 or THP-1 cells. These results demonstrated that IM-133N could stimulate NO and induced pro-inflammatory cytokine expression by monocytes/macrophages. As clinical studies have shown IM-133N to be an effective immunomodulator without any adverse effects, the results of the present study provide further support for the potential use of this agent as an immunostimulant or as an immunotherapy adjuvant.

A contemporary approach on design, development, and evaluation of Ayurvedic formulation - Triphala Guggulu.

INTRODUCTION: Ayurvedic texts describe many formulations for different ailments. Triphala Guggulu (TG) is reputed for treating inflammatory conditions. These formulations have been considered complementary medicine or alternative to conventional medicines across the globe. These complex polyherbal formulations need science-based approach toward manufacturing process and chemical standardization. AIM: To evaluate TG tablets to meet modern pharmaceutical approaches and also standardization processes. MATERIALS AND METHODS: Shodhana of Guggulu was performed using Triphala Kwatha (decoction) as mentioned in ayurvedic texts. This processed material was dried using spray drying technique, blended with other herbal powders as per formula and using suitable excipients was incorporated for compressing into tablets. Excipients and their concentrations were evaluated for various micromeritic properties and the formula that met the requirements was compressed. RESULTS: The angle of repose was considered fair with a range of 25-30, Carr's index at a range between 17 and 30, and Hausner ratio of 1.21:1.44, which was well within the limits as per the United States Pharmacopeia (USP) and among the three blends tested, blend Triphala Guggulu formulation-3 was found most suitable for tablets compression. Physical properties were well within the limits as per the USP and disintegration time was within 30 min. CONCLUSION: Modern pharmaceutical processing can very well be adapted for Guggulu preparations.

Hydnocarpus: an ethnopharmacological, phytochemical and pharmacological review.

ETHNOPHARMACOLOGICAL RELEVANCE: The genus Hydnocarpus (Flacourtiaceae) includes forty species that are spread across the globe. In the Indian System of Medicine, Hydnocarpus pentandrus (Buch.-Ham.) Oken. is primarily used for treating leprosy and other skin disorders. It is known as "Chaulmoogra" and is also used to treat other indications including constipation, inflammation, blood disorders, and worm infestations. Various species of Hydnocarpus are also used in traditional medicine in China, Thailand, Malaysia, and Myanmar for several skin disorders. To assess the therapeutic potential of species from the Hydnocarpus genus and to determine future avenues for research. METHODS: All relevant scientific literature published up to the end of December 2013 was retrieved via a library and electronic search (SciFinder, PubMed, ScienceDirect, and Google Scholar). Manual searches of traditional books like to ancient classics, including Vaidya Yoga Ratnavali, Siddha Materia Medica, and contemporary references including The Ayurvedic Pharmacopoeia of India and The Ayurveda Formulary, were also performed. RESULTS: Seed oil from species of the Hydnocarpus genus is used for medicinal purposes, predominantly for various skin disorders. This oil is reported to contain a characteristic class of compounds known as cyclopentenyl fatty acids. Furthermore, seeds of this genus are reported to contain triglycerides of fatty acids, sterols, flavonoids, and flavonolignans. Hydnocarpin, a flavonolignan, is reported to potentiate antimicrobial and anticancer activity. The extracts and compounds isolated from this plant show a wide spectrum of pharmacological properties, including antibacterial, antileprotic, antitubercular, antipsoriatic, antirheumatic, hypolipidemic, antidiabetic, anticancer, anti-inflammatory, and antioxidant activities. The antileprotic activity is postulated to be due to the cyclopentenyl fatty acids present in the seed oil. CONCLUSION: Flavonolignans have an interesting chemical motif, and hydnocarpin and its congeners should be investigated for their activities and the mechanism underlying these activities. Multi-drug-resistant microbes are on the increase, and the possible inhibitory effect of these compounds when used with current antimicrobials should also be evaluated. Furthermore, unique cyclopentenyl fatty acids should also be investigated to understand the exact mechanism of action underlying antileprotic activity. Additional in depth phytochemical investigations of seed oil and extracts are required to tap the true potential of species from the Hydnocarpus genus.

Assessment of inhibitory potential of Pothos scandens L. on ovalbumin-induced airway hyperresponsiveness in balb/c mice.

Pothos scandens L. was used in Indian traditional medicine as an antiasthmatic drug. The ethanolic and aqueous extracts were prepared with aerial parts of P. scandens (PSE & PSA). ESI MS/MS of PSE ethanolic extract was carried out for the determination of chemical constituents. CP1 is isolated from the PSE, structurally confirmed with NMR and LCMS/MS. PSE, PSA and CP1 are evaluated against ovalbumin (OVA) induced airway hyperresponsiveness (AHR) in balb/c mice. The test drugs are administered p.o. prior to challenge with aerosolized 2.5% w/v OVA. Total and differential leucocyte count, nitrite (NO2), nitrate (NO3), tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and interleukin-13 (IL-13) are estimated in bronchoalveolar lavage fluid (BALF). Similarly, myeloperoxidase (MPO), malonaldehyde (MDA) and total lung protein (TLP) are estimated in the lungs. The results reveal a significant increase in total and differential leucocyte count, NO2, NO3, TNF-α, IL-6, and IL-13 in OVA induced AHR. However, these parameters are significantly decreased in PSE and PSA tested doses (PSE 100 & 200mg/kg). While, treatment with CP1 is less effective at 5 & 10mg/kg doses. Similar observations obtain for MPO and MDA in lungs. However, the mean value indicated that the PSE at 200mg/kg showed a significant restoration in all the parameters. Pro-inflammatory mediators are known to be responsible for AHR. Histopathology revealed justifies the effectiveness. The present investigations suggest PSE are interesting molecules for further research for asthma, with an approach through pro-inflammatory inhibitory pathway. P. scandens is a potential herbal medicine for allergy induced asthma.

Vitamin D2 from light-exposed edible mushrooms is safe, bioavailable and effectively supports bone growth in rats.

UNLABELLED: Widespread poor vitamin D status, a health risk for bone disease, increases the need for new food sources of vitamin D. Light-exposed edible mushrooms synthesize vitamin D(2). Bioavailability, safety, and efficacy of high levels of vitamin D(2) from mushrooms to support bone health was established in chronically fed growing rats. INTRODUCTION: Poor vitamin D status from reduced sun exposure is made worse by limited access to vitamin D-containing foods. Exposing white button mushrooms to ultraviolet B (UVB) light markedly increases their vitamin D(2) content, creating a new food source of vitamin D. We used a growing rat model to determine safety, bioavailability, and efficacy in support of bone growth by vitamin D(2) from UVB-exposed mushrooms. METHODS: We fed 150 weanling female rats one of five diets for 10 weeks, all formulated on AIN-93 G. Control diets contained no mushrooms either with or without vitamin D(3). Other diets contained 2.5% and 5.0% of UVB-exposed or -unexposed mushrooms. Safety of the high levels of vitamin D(2) from mushrooms was assessed by animal growth and by Von Kossa staining for soft tissue calcification. Bioavailability was determined from changes in circulating levels of 25-hydroxyvitamin D [25(OH)D] and parathyroid hormone (PTH). Efficacy in support of bone growth was determined from measures of femur bending properties, size, mineralization, and microarchitecture. RESULTS: Diets containing 2.5% and 5.0% light-exposed mushrooms significantly raised 25(OH)D and suppressed PTH levels compared to control-fed rats or rats fed 5.0% mushroom unexposed to light. Microarchitecture and trabecular mineralization were only modestly higher in the light-treated mushroom-fed rats compared to the controls. Von Kossa staining revealed no soft tissue calcification despite very high plasma 25(OH)D. CONCLUSIONS: Vitamin D(2) from UVB-exposed mushrooms is bioavailable, safe, and functional in supporting bone growth and mineralization in a growing rat model without evidence of toxicity.

Identity and pharmacognosy of Ruta graveolens Linn.

Ruta graveolens L., is a odoriferous herb belonging to the family Rutaceae. It is the source of Rue or Rue oil, called as Sadab or Satab in Hindi. It is distributed throughout the world and cultivated as a medicinal and ornamental herb. The ancient Greeks and Romans, held the plant in high esteem. It is used in Ayurveda, Homoeopathy and Unani. Phytochemical constituents and pharmacological properties were studied in depth. In 14 species of genus Ruta, R. graveolens and R. chalepensis are available in India and also cultivated in gardens. Taxonomical characters to identify the Indian plants are very clear with fringed and or non-fringed petals. However, references to it are confused in the traditional literature. Due to sharing of regional language name, its identity is confused with Euphorbia dracunculoides. Morphological and anatomical characters were described. Pharmacognostic studies with microscopic characters were also published. Upon reviewing the anatomical characters and pharmacognostic characters one finds that it is highly confused and conflicting. The characters described are opposite of each other and authenticity of the market sample of R. graveolens cannot be guaranteed and able to be differentiated from R. chalepensis. Present work is to describe the pharmacognostic characters of R. graveolens to differentiate it from R. chalepensis. It is concluded that morphologically, R. graveolens can be identified with its non-fringed petals and blunted apices of fruit lobes. Whereas, in R. chalepensis petals are fringed or ciliated and apices of the fruit lobes are sharp and projected. Microscopically, in stem of R. graveolens pericyclic fibers have wide lumen. Whereas, in R. chalepensis, it is narrow. The published pharmacognosy reports do not pertain to authentic plant or some of the characteristic features like glandular trichomes are not observed in our samples.

Botanical pharmacognosy of stem of Gmelina asiatica Linn.

Gmelina asiatica Linn (G. parvifolia Roxb.) is a large shrub or a small tree. Roots and aerial parts are used in Ayurvedic medicine and also have ethno-medical uses. Root is reported as adulterant to G. arborea roxb roots. Pharmacognostical characters of root were reported. Owing to the shortage of genuine drug and ever-increasing demands in market, it becomes necessary to search an alternative with equal efficacy without compromising the therapeutic value. Nowadays, it becomes a common practice of using stem. In case of roots phytochemical and pharmacological analysis of stem was reported. However, there is no report on the pharmacognostical characters of stem and to differentiate it from roots. The present report describes the botanical pharmacognostical characters of stem and a note to differentiate it from root. Hollow pith, faint annual rings in cut ends, alternatively arranged macrosclereids and bundle cap fibers, and presence of abundant starch grains and calcium oxalates in pith and in ray cells are the diagnostic microscopic characters of stem. Stem pieces can be differentiated from roots by absence of tylosis.

Pharmacognostical Studies on Balanophora fungosa - a Negative Listed Plant.

Balanophora fungosa Forster & Forster ssp. indica (Arn.) B. Hansen var. indica, (Balanophoraceae) syn. B. indica, is a root parasite found in hills of south India. This plant is included in the list of negative list, which are restricted and prohibited for export. Though it is not an official drug in any of the indigenous systems of medicine in India, it is used in tribal medicines in south India. However, it is found in crude drug markets as substitute/adulterant for the Ayurvedic drug Gajapippali (Scindapsus officinalis). Few phytochemical constituents were reported on this plant. However, there is no pharmacognostical report to authenticate the commercial samples of B. fungosa and to differentiate them from Scindapsus officinalis. This article describes the pharmacognostical characteristics of Balanophora fungosa and diagnostic features to differentiate it from Scindapsus officinalis.

Effects of direct-fed microbials on growth performance, gut morphometry, and immune characteristics in broiler chickens.

This study was conducted to compare growth performance, gut morphometry, and parameters of local and systemic immunity in broiler chickens fed for 22 consecutive days with a diet supplemented with Bacillus spp. as direct-fed microbials (DFM), a commercial product incorporating 3 DFM, or a nonsupplemented diet. Direct-fed microbials did not significantly modify BW gain and most failed to affect serum antibody levels in response to immunization with a recombinant Eimeria protein. However, altered intestinal morphometric measurements were readily apparent in DFM-fed chickens as revealed by increased villus height and crypt depth compared with non-DFM-fed controls. In addition, serum levels of alpha-1-acid glycoprotein as an inflammatory marker were reduced in DFM-fed birds, whereas splenic lymphocyte proliferation, intestine intraepithelial lymphocyte subpopulations, and cytokine mRNA levels in intraepithelial lymphocytes were increased, decreased, or unchanged compared with controls depending on the DFM used. These results provide a rational scientific basis for future studies to investigate DFM as immunomodulating agents to enhance host protective immunity against enteric pathogens in broiler chickens.
