The 'gall', provides food and shelter for its insects and mites. In many cases, the galls induced by the parasites attain phenomenal structural complexity and architectural design which have allured the naturalists. In a survey of plant-galls in Tamil Nadu Forests in South India, we were able to record several remarkable galls of excelling architectural designs and sublime marvels. A few such illustrious galls and new reports are highlighted here.Keywords

Background/Objectives:The collection of raw phytodrugs by untrained personnel may lead to unintentional adulteration of drugs. Intentional adulteration or substitution is also a menace in the crude drug markets.Methods/Statistical Analysis: To detect the adulterants from the original ones, the crude drugs are subjected for microscopic analysis including anatomical parameters. The microscopic observations on the gross anatomical features coupled with tissue disposition and cell inclusions are more reliable techniques in the crude samples of ischolar_main drugs.
Findings: The present paper deals with two ischolar_main drugs, popularly used in Indian System of Medicine, highlights the anatomical differences namely Aerva lanata (L.) Juss. ex Schultes and Aerva persica (Burm. f.) Merr.
Application/Improvements: The possible reasons for ischolar_main drug similarities and differences are discussed. Such inquire may find use further in the pharmaceutical applications of these two species.

Background/Objectives: The new millennium is witnessing a profound resurgence in the traditional system of clinical application of the native herbal drugs. This has eventually led to the discovery of hundreds of new plant drugs, which are believed to possess therapeutic potentials.
Methods/Statistical Analysis: To detect the adulterants from the original ones by mere spotting at sight is unscientific and unreliable under such situation, the crude drugs are to be subjected to microscopic analysis and anatomical parameters.
Findings: The present paper deals with two ischolar_main drugs, popularly used in Indian System of Medicine, namely Gmelina arborea Roxb. and Gmelina asiatica L. The result findings highlight the anatomical differences of these two taxa.
Application/Improvements: Gmelina arborea Roxb. is an important ingredient of 'Dasamula' preparation, restricted availability of this drug leads to adulterate Gmelina asiatica L. with the previous drug. However microscopic characters of these two ischolar_main drugs helpful for analyzing to separating each other.

Journal of Health Science Research, Vol 1, No 2 (2016), Pagination: 37-41Abstract
Background: Ankylosing Spondulitis is a chronic inflammatory disease of the axial skeleton with variable involvements of the peripheral joints. Symptoms appear gradually with pain and stiffness especially in the morning. As the disease progresses, loss of spinal mobility and chest expansion with limitation of anterior flexion, lateral flexion, and extension of the lumbar spine, are seen. Pain is often severe at rest, but improves with physical activity. Though physical therapy remedies have been scarcely documented, therapeutic exercises are used to help manage pain and improve functions. Methodology: 10 patients (8 males) diagnosed with ankylosing spondylitis with HLA-B27 antigen positive participated in the study. After basic evaluation, the patients were asked to fill the quality of life questionnaire and hospital anxiety depression scale. Physical therapy exercises were introduced for a period of 4 weeks. The outcome measures were reassessed after this. The data thus obtained, was then statistically analyzed. Results: The mean age of patients was 26 years with the mean duration of the disease about 1 year and 2 months. Both the scales showed decreased scores post physiotherapy. Conclusion: Physical therapy improved the quality of life in patients with Ankylosing Spondylitis. Patients were seen to be depressed and anxious due to the disease process. Also, financial status gets affected due to expenditure on medicines and surgical interventions further affecting the psychological status.Keywords

Objectives: The mechanism underlying the morphological and structural specificity of galls attributable to particular insect species is very little understood. The present study is a fragment of the galls found in the Nilgris and Courtallum Hills in India and the study has offered some interesting results and conclusions.
Methods/Statistical Analysis: A comprehensive study on two leaf galls exhibiting evidently different ontogenetic sequences is attempted in the present investigation.
Findings: We studied histology of maturefoliar galls on two host plants caused by different insect species. The pit-gall on Mallotusphilippensis is simple in structure with homogeneous parenchymatous tissue. The galls on Alstoniascholaris and Magniferaindica are more complex in structure.
Application/Improvements: Cecidological studies gain popularity nowadays as they form the most conspicuous elements of the terrestrial ecosystem. The role of the insect behavior is considered as the major factor in determining the form and structure of the gall that an insect incites.

Background/Objectives: Most of the species of Datura imposes a wide lacuna in our knowledge especially for proper identification and pharmacognostical studies. Anatomical structure is most likely to provide evidence concerning the interrelationships of families or in establishing the real affinities of species of uncertain taxonomic status.
Methods/Statistical Analysis: The wood anatomical characters and certain ‘anomalous’ or uncommon structures of the axis have been extensively employed by the systematic anatomists for drawing conclusion with reference to systematic position and phylogeny of plant taxa. Apart from anatomical and trichome studies, palynological investigation is also to be attempted. This will give additional information both for diagnosis of the plants and for conformation their taxonomic position.
Findings: In Datura species epidermal trichomes have been cited as one of the criteria for distinguishing the species. The cross sectional outline of young stem differs significantly in the species studied. The cross section shape is circular and densely pubescent in Datura innoxia, angular in Datura fastuosa. The secondary xylems of ischolar_mains are uniformly dense with wide cylinder of libriform fibres and vessels. The vessels of the ischolar_main are wider than those of the stem. The ischolar_mains of Datura species deviate in their secondary xylem features from the rest of the taxa. These cross sectional configurations are easy access for identification of fragmentary stem materials.
Application/Improvements: An attempt will be made to prepare an artificial dichotomous taxonomic key involving anatomical and palynological data obtained during the present investigations.

Background/Objectives: Some of the anatomical characters are liable to become modification in response to environmental change; however, many characters are more fixed genetically and such characters are to be employed for taxonomic studies. For distinguishing two species, differences in the anatomical structures usually provide much reliable grounds for identification.
Methods/Statistical Analysis: For anatomical studies the customary techniques of sectioning and staining will be followed. It is aimed to collect data of anatomical characters of easily available plant parts such as leaf, petiole, stem and ischolar_main. It is hoped that these studies will enable anybody to identify the plants concerned in the sterile or fragmentary conditions.
Findings: Anatomical structure is most likely to provide evidence concerning the interrelationships to families or in establishing the real affinities of genera of uncertain taxonomic status.
Application/Improvements: Microscopical studies are also very essential tool to establish the botanical identity of commercial samples of medicinal value and may also aid in checking adulteration or substitution. Apart from anatomical studies, palynological investigation is also to be attempted. This will give additional information both for diagnosis of the plants and for confirmation of their taxonomic position.
