It consists of many layers of thin-walled parenchyma cells with lot of intercellular spaces cheap 500 mg panmycin mastercard. It is composed of single layer of barrel shaped 83 Root hair Rhizodermis Cortex Endodermis Pith Ground plan Root hair Rhizodermis Cortex Passage cell Casparian strip Endodermis Pericycle Passage cell Phloem Protoxylem Metaxylem Pith A sector enlarged Fig panmycin 250mg without a prescription. There is a band like structure made of suberin present in the radial and transverse walls of the endodermal cells discount panmycin 500 mg free shipping. Their function is to transport water and dissolved salts from the cortex to the xylem. The main function of casparian strips in the endodermal cells is to prevent the re-entry of water into the cortex once water entered the xylem tissue. Pericycle Pericycle is the outermost layer of the stele and lies inner to the endodermis. The tissue, which is present between the xylem and the phloem, is called conjunctive tissue. Primary structure of dicotyledonous root - Bean root The transverse section of the dicot root (Bean) shows the following plan of arrangement of tissues from the periphery to the centre. It is made up of a single layer of parenchyma cells which are arranged compactly without intercellular spaces. These cells are loosely arranged with intercellular spaces to make gaseous exchange easier. Though chloroplasts are absent in the cortical cells, starch grains are stored in them. The radial and the inner tangential walls of endodermal cells are thickened with suberin. But these casparian strips are absent in the endodermal cells which are located opposite to the protoxylem elements. These thin- walled cells without casparian strips are called passage cells through which water and mineral salts are conducted from the cortex to the xylem elements. Water cannot pass through other endodermal cells due to the presence of casparian thickenings. Pericycle Pericycle is generally a single layer of parenchymatous cells found inner to the endodermis. Anatomy of monocot and dicot stems Primary structure of monocot stem - Maize stem The outline of the maize stem in transverse section is more or less circular. Internal structure of monocotyledonous stem reveals epidermis, hypodermis, ground tissue and vascular bundles. The continuity of this layer may be broken here and there by the presence of a few stomata. Hypodermis A few layer of sclerenchymatous cells lying below the epidermis constitute the hypodermis.. Ground tissue There is no distinction into cortex, endodermis, pericycle and pith. The entire mass of parenchymatous cells lying inner to the hypodermis forms the ground tissue. The cells of the ground tissue next to the hypodermis are smaller in size, polygonal in shape and compactly arranged. Towards the centre, the cells are loosely arranged, rounded in shape and bigger in size. Vascular bundles Vascular bundles are scattered in the parenchymatous ground tissue. Each vascular bundle is surrounded by a sheath of sclerenchymatous fibres called bundle sheath. Vascular bundles are numerous, small and closely arranged in the peripheral portion. Towards the centre, the bundles are comparatively large in size and loosely arranged. It can be distinguished into an outer crushed protophloem and an inner metaphloem. The two metaxylem vessels are located at the upper two arms and one or two protoxylem vessels at the base. In a mature bundle, the lowest protoxylem disintegrates and forms a cavity known as protoxylem lacuna. Primary structure of dicotyledonous stem - Sunflower stem Internal structure of dicotyledonous stem reveals epidermis, cortex and stele. Inner to the hypodermis, a few layers of chlorenchyma cells are present with conspicuous intercellular spaces. The cells of this layer are barrel shaped and arranged compactly without intercellular 92 Epidermal hair Epidermis Hypodermis Cortex Endodermis Pericycle Vascular bundle Pith Ground plan Epidermal hair Cuticle Epidermis Collenchyma Chlorenchyma Cortex Resin duct Parenchyma Starch sheath Bundle cap Primary phloem Cambium Metaxylem Protoxylem Pith Primary medullary ray A sector enlarged Fig. Since starch grains are abundant in these cells, this layer is also known as starch sheath. Pericycle Pericycle is the layers of cells that occur between the endodermis and vascular bundles. In the stem of sunflower (Helianthus), a few layers of sclerenchyma cells occur in patches outside the phloem in each vascular bundle. The bundle caps and the parenchyma cells between them constitute the pericycle in the stem of sunflower. Phloem conducts organic food materials from the leaves to other parts of the plant body. Xylem conducts water and minerals from the root to the other parts of the plant body. These extensions of the pith between the vascular bundles are called primary pith rays or primary medullary rays. Anatomical differences between dicot stem and monocot stem Dicot stem Monocot stem 1. Ground tissue is not differen- into cortex, endodermis, tiated, but it is a continuous mass pericycle and pith. When the xylem and the phloem lie in the same radius, the vascular bundle is called a.
The presence in the list of reference of indicators like i/ Frequency of daily intake of food and drink of people buy panmycin 500mg with visa, ii/ Proportion of dentists providing advice on tobacco use cessation to their patients order panmycin from india, iii/ Incidence annual of oral cancer in adults contribute of laying common foundations for an integrated approach of health surveillance buy panmycin 250mg with visa.. A critical analysis of the methodological criteria used in international scientific literature has underlined that new and complementary trends should be recommended to improve the production of higher quality information in oral health epidemiology. Standardized procedures including health interview and health clinical surveys in relation with core indicators should be developed and used. Similarly, thought should be given to the design and implementation of an Oral Health Surveillance System, based on oral health primary care providers which would support national health surveillance systems such as Health National Interview Survey and Health National Clinical Survey. The analysis of the scientific literature showed weaknesses in the evaluation of oral health trends in terms of methodology, quality control, and presentation of results. The ability to interpret and make conclusions in public oral health are therefore limited. New or complementary measures should be put in place in order to improve the quality of medical information in oral health epidemiology. The range of potential quality methods is vast, making a full review impracticable. Existing data sources might not permit the construction of the desired indicators, because the required variables are missing or recorded differently. Dedicated data collection that would yield comparable information on a national level might be prohibively expensive. Thus, to tackle the problem in a way that respects time and resource constraints, an opportunistic rather than idealistic approach seems warranted. The main disadvantage of relying on existing data sources is that the data systems have usually been designed for purposes other than quality measurement and may therefore not always provide exactly the desired information. The following limitations are commonly observed: Limited geographic coverage in several countries, data are only available for selected regions. However, the distribution of caries is very skewed and although risk groups are increasingly targeted for prevention, appropriate and prudent surveillance and care should be provided for all patients since caries can occur and can progress in all risk groups. The population presenting oral disorders need care adopting a longitudinal perspective, with an emphasis on prevention and health promotion.. In dental caries management, the focus has been around preventive caries management for children, but caries is a disease process that needs to be managed over a persons lifetime. The evidence is leading to an international trend in clinical practice, to move away from operative intervention towards prevention of caries. The dentist in the particular scope of their exercises, indeed have to make pay their attention focus on two types of approaches. They have to attempt in the first place to prevent the occurrence of chronic oral health diseases - caregivers of children could play a major part in keeping children free of obvious dental caries. This by setting up an optimal treatment and by providing best practices for managing oral diseases once they have been diagnosed. Oral health information systems--towards measuring progress in oral health promotion and disease prevention. Are we ready to move from operative to non-operative/preventive treatment of dental caries in clinical practice? Although useful and even essential, comparisons between countries have many caveats (Kosonen 1994, Kautto & Moisio 2004, Gissler et al. An important condition is comparable units of measurements, and therefore creation and development of indicators is essential (Kosonen 1994). Without reliable indicators a picture of a situation or developments may remain ambiguous. The lack of standardisation both in indicator definitions and methods of measurement has hindered international comparisons (Koponen & Aromaa 2006). It also includes sexual health, the purpose of which is the enhancement of life and personal relationships, and not merely counseling and care related to reproductive and sexually transmitted diseases. For each indicator there is an operational definition, justification for selection, criteria for selection, data sources and (when appropriated) references. A systematic review of factors associated with teenage pregnancy in European Union (Imamura, 2007). Results came from 4444 studies identified and screened, 20 met the inclusion criteria. The well-recognized factors of socioeconomic disadvantage disrupted family structure and low educational level and aspiration appear consistently associated with teenage pregnancy. However, surprisingly for some of us, evidence that access to services in itself is a protective factor remains inconsistent. Although further association with diverse risk-taking behaviours and lifestyle, sexual health knowledge, attitudes and behaviour are reported, the independent effects of these factors too remain unclear. Another conclusion resulting from the systematic review was that included studies varied widely in terms of methods and definitions used. First, we cannot synthesize or generalize key findings as to how all these factors interact with one another and which factors are the most significant. Future research ensuring comparability and generalizability of results related to teenage sexual health outcomes will help gain insight into the international variation in observed pregnancy rates and better inform interventions (Imamura, 2007). Friends, books and magazines were the most important source of information on puberty for every country. School teachers appeared as one of he most important sources of information of sexual and reproductive systems of men and women. In every country the large majority of respondents had already had a boy or girl friend: 76. More than 47% (between 47% in Estonia and 58% in Belgium) respondents had already had heterosexual intercourse. However, some outcomes of this apparently similar sexual and reproductive behaviour of young people is obviously different when considering the same four Member States. Teenage pregnancy is a good example, with rates, 1n 2005, varying between 6% in Portugal and 2 % in Belgium (Estonia with 4 % and Czech Republic 1 %). This seems to be due to either one of the following reason: contraceptive failure (Portugal, for instance, having a huge use of emergency contraception, with sales increasing enormously from 80.

Once performed, colposcopic evaluation is usually followed closely for at least 12 years. The cervix is more vascular (increased blood supply) in pregnancy and there is an increased risk of bleeding. It is usually done to evaluate any lesions suspected of representing abnormal tissue growth or cancer.

If there is dyspnoea from a pleural effusion, Remember the possibility of complications and drain it (9. Make the diagnosis of malignant disease clinically, and examine the patient carefully to assess its extent. If you are sending away a node for histology, always cut it across: with experience you will be able to recognize the caseation of tuberculosis, and to distinguish hyperplasia from a tumour. However, after taking a biopsy for malignancy, wait for the histological report before starting toxic chemotherapy. When you take tissue from an ulcer or a large mass, take some from the edge of the lesion, so that you include normal and abnormal tissue. Most malignant tumours have 4 stages, or sometimes 5, some of which may be subdivided. The first 2 stages are usually curable, whereas the last 2 can usually only be palliated. Both the stage of a tumour, and often its histological grade, influence the prognosis, both with and without treatment. Occasionally, you will see some large resectable tumours, malignant or benign (24-7).
