Antinociceptive and antiedematogenic properties and acute toxicity of Tabebuia avellanedae Lor. ex Griseb. inner bark aqueous extract. (3/477)

BACKGROUND: Tabebuia avellanedae is a tree from the Bignoniaceae family. Commonly know as "pau d'arco" in Brazil, its inner bark is used as analgesic, anti-inflammatory, antineoplasic and diuretic at the Brazilian northeast. A validation of the plant usage has not been previously performed. RESULTS: Antinociceptive and antiedematogenic effects of Tabebuia avellanedae Lor. ex Griseb. inner bark were measured by nociceptive experimental models in mice. A rat paw edema test induced by carrageenan (1%) was also performed in rats to access the plant's antiedematogenic effect. The inner bark aqueous extract, administered via oral in three different concentration, namely 100, 200 and 400 mg/Kg, reduced the nociception produced by acetic acid (0.6% in water, i.p.) by 49.9%, 63.7% and 43.8%, respectively. The aqueous extract (200 and 400 mg/Kg, p.o.) reduced formalin (1%) effects only at the second phase of the experiment by 49.3% and 53.7%, respectively. Naloxone (5 mg/Kg, i.p.) was not able to revert the extract effect, however caffeine (10 mg/Kg, i.p.) reverted its effect by 19.8% at the second phase of the formalin test. The aqueous extract (200 mg/Kg, p.o.) inhibited edema by 12.9% when we used the rat paw edema model. The acute toxicity was low in mice. CONCLUSION: The T. avellanedae inner bark aqueous extract presented antinociceptive and antiedematogenic activities at the used models, with a possible antinociceptive effect associated to the adenosine system.  (+info)

Stem diameter variations and cold hardiness in walnut trees. (4/477)

The effect of freezing temperatures on stem diameter was measured in the field and in climatic chambers using linear variable differential transformers (LVDT sensors). In acclimated stems, there was reversible stem shrinkage associated with freeze-thaw cycles. The maximum shrinkage correlated with stem diameter (thickness of the bark). The wood was responsible for only 15% of the shrinkage associated with a freeze event, and experiments with isolated bark showed that connection with the wood was not necessary for most of the freeze-induced shrinkage to occur. Considering the amount of stem shrinkage associated with summer drought in walnut, the amount of contraction of the bark with freezing was actually much less than might be predicted by water relations theory. Reversible stem shrinkage occurred in living tissues, but not in autoclaved tissues. For the latter, swelling was observed with freezing and this swelling could be explained by the bark alone. Similar swelling was observed during September and October for non-acclimated plants. Water was lost with each freeze-thaw cycle starting with the first, and freezing injury of the bark, with discoloration of tissues, was also observed in non-acclimated plants. Given that the diameter fluctuation patterns were dramatically different for acclimated versus non-acclimated plants, and for living versus autoclaved tissues, LVDT sensors could represent a novel, non-invasive approach to testing cold hardiness.  (+info)

Antiproliferative constituents in the plants 7. Leaves of Clerodendron bungei and leaves and bark of C. trichotomum. (6/477)

The constituents of the leaves of Clerodendron bungei STEUD. (Verbenaceae) and leaves and bark of C. trichotomum THUNB. were investigated guided by the antiproliferative activity against three tumor cell lines (MK-1: human gastric adenocarcinoma, HeLa: human uterus carcinoma, and B16F10: murine melanoma). Two phenylethanoid glycoside caffeic acid esters, acteoside and isoacteoside, were isolated as the constituents which selectively inhibit the growth of B16F10 cells. The antiproliferative activities against B16F10 cells of acteoside (GI50: 8 microM), isoacteoside (8 microM) and their methanolysis products, methyl caffeate (26 microM), 3,4-dihydroxyphenethyl alcohol (8 microM), 3,4-dihydroxyphenethyl glucoside (10 microM), desrhamnosyl acteoside (6 microM), and desrhamnosyl isoacteoside (6 microm) suggested that the 3,4-dihydroxyphenethyl alcohol group might be more responsible for the activities of acteoside and isoacteoside than the caffeoyl group. The activities of chlorogenic acid, 3,4-dihydroxyphenylacetic acid, 3-(3,4-dihydroxyphenyl) alanine, 3,4-dihydroxy-phenethylamine hydrochloride, ferulic acid, sinapic acid, and five dihydroxybenzoic acids were also determined and compared with those of the above compounds.  (+info)

Anti-tumor-promoting activity of the diterpene from Excoecaria agallocha. II. (7/477)

Eight new diterpenoids (1-8) have been isolated from the wood of Excoecaria agallocha (Euphorbiaceae) and their inhibitory effects on the induction of Epstein-Barr virus early antigen (EBV-EA) in Raji cells were examined to search for potent anti-tumor-promoters from natural resources. Of these compounds, the secolabdane-type diterpenoid, compound 7 exhibited a remarkable inhibitory effect on EBV-EA induction, and a significant anti-tumor-promoting effect in the mouse two-stage carcinogenesis test using 7,12-dimethylbenz[a]anthracene and 12-O-tetradecanovl-phorbol-13-acetate.  (+info)

I'm sorry for any confusion, but "Plant Bark" is not a term with a specific medical definition. In general, the bark refers to the outermost covering of a tree or other plant, which serves as protection and provides a barrier against external threats. It is composed of layers including the inner bark (phloem), which transports nutrients throughout the plant, and the outer bark (periderm), which is made up of dead cells that form a protective layer.

While some plants or plant parts do have medicinal properties and are used in various forms of traditional or alternative medicine, "Plant Bark" by itself does not have any specific medical connotations. If you're referring to a specific type of plant bark with potential medicinal uses, please provide more details so I can give a more accurate response.

Genetically modified plants (GMPs) are plants that have had their DNA altered through genetic engineering techniques to exhibit desired traits. These modifications can be made to enhance certain characteristics such as increased resistance to pests, improved tolerance to environmental stresses like drought or salinity, or enhanced nutritional content. The process often involves introducing genes from other organisms, such as bacteria or viruses, into the plant's genome. Examples of GMPs include Bt cotton, which has a gene from the bacterium Bacillus thuringiensis that makes it resistant to certain pests, and golden rice, which is engineered to contain higher levels of beta-carotene, a precursor to vitamin A. It's important to note that genetically modified plants are subject to rigorous testing and regulation to ensure their safety for human consumption and environmental impact before they are approved for commercial use.

I believe there may be a slight misunderstanding in your question. "Plant leaves" are not a medical term, but rather a general biological term referring to a specific organ found in plants.

Leaves are organs that are typically flat and broad, and they are the primary site of photosynthesis in most plants. They are usually green due to the presence of chlorophyll, which is essential for capturing sunlight and converting it into chemical energy through photosynthesis.

While leaves do not have a direct medical definition, understanding their structure and function can be important in various medical fields, such as pharmacognosy (the study of medicinal plants) or environmental health. For example, certain plant leaves may contain bioactive compounds that have therapeutic potential, while others may produce allergens or toxins that can impact human health.

"Plant proteins" refer to the proteins that are derived from plant sources. These can include proteins from legumes such as beans, lentils, and peas, as well as proteins from grains like wheat, rice, and corn. Other sources of plant proteins include nuts, seeds, and vegetables.

Plant proteins are made up of individual amino acids, which are the building blocks of protein. While animal-based proteins typically contain all of the essential amino acids that the body needs to function properly, many plant-based proteins may be lacking in one or more of these essential amino acids. However, by consuming a variety of plant-based foods throughout the day, it is possible to get all of the essential amino acids that the body needs from plant sources alone.

Plant proteins are often lower in calories and saturated fat than animal proteins, making them a popular choice for those following a vegetarian or vegan diet, as well as those looking to maintain a healthy weight or reduce their risk of chronic diseases such as heart disease and cancer. Additionally, plant proteins have been shown to have a number of health benefits, including improving gut health, reducing inflammation, and supporting muscle growth and repair.

A plant extract is a preparation containing chemical constituents that have been extracted from a plant using a solvent. The resulting extract may contain a single compound or a mixture of several compounds, depending on the extraction process and the specific plant material used. These extracts are often used in various industries including pharmaceuticals, nutraceuticals, cosmetics, and food and beverage, due to their potential therapeutic or beneficial properties. The composition of plant extracts can vary widely, and it is important to ensure their quality, safety, and efficacy before use in any application.

A plant root is not a medical term per se, but it is a term from botany, which is the study of plants. However, I can certainly provide a definition for you.

Plant roots are the underground organs of a plant that typically grow downward into the soil. They serve several important functions, including:

1. Anchorage: Roots help to stabilize the plant and keep it upright in the ground.
2. Absorption: Roots absorb water and nutrients from the soil, which are essential for the plant's growth and development.
3. Conduction: Roots conduct water and nutrients up to the above-ground parts of the plant, such as the stem and leaves.
4. Vegetative reproduction: Some plants can reproduce vegetatively through their roots, producing new plants from root fragments or specialized structures called rhizomes or tubers.

Roots are composed of several different tissues, including the epidermis, cortex, endodermis, and vascular tissue. The epidermis is the outermost layer of the root, which secretes a waxy substance called suberin that helps to prevent water loss. The cortex is the middle layer of the root, which contains cells that store carbohydrates and other nutrients. The endodermis is a thin layer of cells that surrounds the vascular tissue and regulates the movement of water and solutes into and out of the root. The vascular tissue consists of xylem and phloem, which transport water and nutrients throughout the plant.

A gene in plants, like in other organisms, is a hereditary unit that carries genetic information from one generation to the next. It is a segment of DNA (deoxyribonucleic acid) that contains the instructions for the development and function of an organism. Genes in plants determine various traits such as flower color, plant height, resistance to diseases, and many others. They are responsible for encoding proteins and RNA molecules that play crucial roles in the growth, development, and reproduction of plants. Plant genes can be manipulated through traditional breeding methods or genetic engineering techniques to improve crop yield, enhance disease resistance, and increase nutritional value.

A medical definition for "plant shoots" may not be readily available, as the term is primarily used in botany and horticulture. However, I can provide you with a general definition:

Plant shoots refer to the above-ground portion of a plant, which typically includes structures like stems, leaves, flowers, and buds. Shoots originate from the seed or the growing tip of the plant and are responsible for photosynthesis, nutrient absorption, and reproduction. In some contexts, "plant shoots" might also refer to new growth that emerges from an existing plant, such as when a leaf or stem sprouts a new branch or flower.

Medicinal plants are defined as those plants that contain naturally occurring chemical compounds which can be used for therapeutic purposes, either directly or indirectly. These plants have been used for centuries in various traditional systems of medicine, such as Ayurveda, Chinese medicine, and Native American medicine, to prevent or treat various health conditions.

Medicinal plants contain a wide variety of bioactive compounds, including alkaloids, flavonoids, tannins, terpenes, and saponins, among others. These compounds have been found to possess various pharmacological properties, such as anti-inflammatory, analgesic, antimicrobial, antioxidant, and anticancer activities.

Medicinal plants can be used in various forms, including whole plant material, extracts, essential oils, and isolated compounds. They can be administered through different routes, such as oral, topical, or respiratory, depending on the desired therapeutic effect.

It is important to note that while medicinal plants have been used safely and effectively for centuries, they should be used with caution and under the guidance of a healthcare professional. Some medicinal plants can interact with prescription medications or have adverse effects if used inappropriately.

A plant stem is not typically defined in a medical context, but rather in the field of botany. However, I can certainly provide a general biological definition for you.

In plants, stems are organs that serve primarily as support structures, holding leaves, flowers, and fruits aloft where they can receive sunlight and exchange gases. They also act as conduits, transporting water, nutrients, and sugars made during photosynthesis between the roots and shoots of a plant.

The stem is usually composed of three main tissue systems: dermal, vascular, and ground. The dermal tissue system forms the outermost layer(s) of the stem, providing protection and sometimes participating in gas exchange. The vascular tissue system contains the xylem (which transports water and nutrients upward) and phloem (which transports sugars and other organic compounds downward). The ground tissue system, located between the dermal and vascular tissues, is responsible for food storage and support.

While not a direct medical definition, understanding the structure and function of plant stems can be relevant in fields such as nutrition, agriculture, and environmental science, which have implications for human health.

DNA, or deoxyribonucleic acid, is the genetic material present in the cells of all living organisms, including plants. In plants, DNA is located in the nucleus of a cell, as well as in chloroplasts and mitochondria. Plant DNA contains the instructions for the development, growth, and function of the plant, and is passed down from one generation to the next through the process of reproduction.

The structure of DNA is a double helix, formed by two strands of nucleotides that are linked together by hydrogen bonds. Each nucleotide contains a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases in DNA: adenine (A), guanine (G), cytosine (C), and thymine (T). Adenine pairs with thymine, and guanine pairs with cytosine, forming the rungs of the ladder that make up the double helix.

The genetic information in DNA is encoded in the sequence of these nitrogenous bases. Large sequences of bases form genes, which provide the instructions for the production of proteins. The process of gene expression involves transcribing the DNA sequence into a complementary RNA molecule, which is then translated into a protein.

Plant DNA is similar to animal DNA in many ways, but there are also some differences. For example, plant DNA contains a higher proportion of repetitive sequences and transposable elements, which are mobile genetic elements that can move around the genome and cause mutations. Additionally, plant cells have cell walls and chloroplasts, which are not present in animal cells, and these structures contain their own DNA.

'Plant development' is not a term typically used in medical definitions, as it is more commonly used in the field of botany to describe the growth and differentiation of plant cells, tissues, and organs over time. However, in a broader context, plant development can be defined as the series of changes and processes that occur from the fertilization of a plant seed to the formation of a mature plant, including germination, emergence, organ formation, growth, and reproduction.

In medicine, terms related to plant development may include "phytotherapy" or "herbal medicine," which refer to the use of plants or plant extracts as medicinal treatments for various health conditions. The study of how these plants develop and produce their active compounds is an important area of research in pharmacology and natural products chemistry.

'Toxic plants' refer to those species of plants that contain toxic substances capable of causing harmful effects or adverse health reactions in humans and animals when ingested, touched, or inhaled. These toxins can cause a range of symptoms from mild irritation to serious conditions such as organ failure, paralysis, or even death depending on the plant, the amount consumed, and the individual's sensitivity to the toxin.

Toxic plants may contain various types of toxins, including alkaloids, glycosides, proteins, resinous substances, and essential oils. Some common examples of toxic plants include poison ivy, poison oak, nightshade, hemlock, oleander, castor bean, and foxglove. It is important to note that some parts of a plant may be toxic while others are not, and the toxicity can also vary depending on the stage of growth or environmental conditions.

If you suspect exposure to a toxic plant, it is essential to seek medical attention immediately and, if possible, bring a sample of the plant for identification.

A plant cell is defined as a type of eukaryotic cell that makes up the structural basis of plants and other forms of multicellular plant-like organisms, such as algae and mosses. These cells are typically characterized by their rigid cell walls, which provide support and protection, and their large vacuoles, which store nutrients and help maintain turgor pressure within the cell.

Plant cells also contain chloroplasts, organelles that carry out photosynthesis and give plants their green color. Other distinctive features of plant cells include a large central vacuole, a complex system of membranes called the endoplasmic reticulum, and numerous mitochondria, which provide energy to the cell through cellular respiration.

Plant cells are genetically distinct from animal cells, and they have unique structures and functions that allow them to carry out photosynthesis, grow and divide, and respond to their environment. Understanding the structure and function of plant cells is essential for understanding how plants grow, develop, and interact with their surroundings.

I'm sorry for any confusion, but "Plant Structures" is not a medical term. It is a term used in the field of botany to refer to the different parts of a plant, such as roots, stems, leaves, flowers, and fruits. Each of these structures has specific functions that contribute to the overall growth, reproduction, and survival of the plant. If you have any questions related to biology or botany, I'd be happy to try and help answer them!

A plant genome refers to the complete set of genetic material or DNA present in the cells of a plant. It contains all the hereditary information necessary for the development and functioning of the plant, including its structural and functional characteristics. The plant genome includes both coding regions that contain instructions for producing proteins and non-coding regions that have various regulatory functions.

The plant genome is composed of several types of DNA molecules, including chromosomes, which are located in the nucleus of the cell. Each chromosome contains one or more genes, which are segments of DNA that code for specific proteins or RNA molecules. Plants typically have multiple sets of chromosomes, with each set containing a complete copy of the genome.

The study of plant genomes is an active area of research in modern biology, with important applications in areas such as crop improvement, evolutionary biology, and medical research. Advances in DNA sequencing technologies have made it possible to determine the complete sequences of many plant genomes, providing valuable insights into their structure, function, and evolution.

'Arabidopsis' is a genus of small flowering plants that are part of the mustard family (Brassicaceae). The most commonly studied species within this genus is 'Arabidopsis thaliana', which is often used as a model organism in plant biology and genetics research. This plant is native to Eurasia and Africa, and it has a small genome that has been fully sequenced. It is known for its short life cycle, self-fertilization, and ease of growth, making it an ideal subject for studying various aspects of plant biology, including development, metabolism, and response to environmental stresses.

Edible plants are those that can be safely consumed by humans and other animals as a source of nutrition. They have various parts (such as fruits, vegetables, seeds, roots, stems, and leaves) that can be used for food after being harvested and prepared properly. Some edible plants have been cultivated and domesticated for agricultural purposes, while others are gathered from the wild. It is important to note that not all plants are safe to eat, and some may even be toxic or deadly if consumed. Proper identification and knowledge of preparation methods are crucial before consuming any plant material.

Plant growth regulators (PGRs) are natural or synthetic chemical substances that, when present in low concentrations, can influence various physiological and biochemical processes in plants. These processes include cell division, elongation, and differentiation; flowering and fruiting; leaf senescence; and stress responses. PGRs can be classified into several categories based on their mode of action and chemical structure, including auxins, gibberellins, cytokinins, abscisic acid, ethylene, and others. They are widely used in agriculture to improve crop yield and quality, regulate plant growth and development, and enhance stress tolerance.

Arabidopsis proteins refer to the proteins that are encoded by the genes in the Arabidopsis thaliana plant, which is a model organism commonly used in plant biology research. This small flowering plant has a compact genome and a short life cycle, making it an ideal subject for studying various biological processes in plants.

Arabidopsis proteins play crucial roles in many cellular functions, such as metabolism, signaling, regulation of gene expression, response to environmental stresses, and developmental processes. Research on Arabidopsis proteins has contributed significantly to our understanding of plant biology and has provided valuable insights into the molecular mechanisms underlying various agronomic traits.

Some examples of Arabidopsis proteins include transcription factors, kinases, phosphatases, receptors, enzymes, and structural proteins. These proteins can be studied using a variety of techniques, such as biochemical assays, protein-protein interaction studies, and genetic approaches, to understand their functions and regulatory mechanisms in plants.

"Plant immunity" refers to the complex defense mechanisms that plants have evolved to protect themselves from pathogens, such as bacteria, viruses, fungi, and nematodes. Plants do not have an adaptive immune system like humans, so they rely on their innate immune responses to detect and respond to pathogen invasion.

Plant immunity can be broadly categorized into two types: PTI (PAMP-triggered immunity) and ETI (Effector-triggered immunity). PTI is activated when the plant recognizes conserved microbial patterns, known as PAMPs (Pathogen-Associated Molecular Patterns), through pattern recognition receptors (PRRs) located on the cell surface. This recognition triggers a series of defense responses, such as the production of reactive oxygen species, the activation of mitogen-activated protein kinases (MAPKs), and the expression of defense genes.

ETI is activated when the plant recognizes effector proteins produced by pathogens to suppress PTI. Effector recognition typically occurs through resistance (R) proteins that can directly or indirectly recognize effectors, leading to the activation of stronger defense responses, such as the hypersensitive response (HR), which involves localized programmed cell death to limit pathogen spread.

Overall, plant immunity is a complex and dynamic process involving multiple layers of defense mechanisms that help plants protect themselves from pathogens and maintain their health and productivity.

Tobacco is not a medical term, but it refers to the leaves of the plant Nicotiana tabacum that are dried and fermented before being used in a variety of ways. Medically speaking, tobacco is often referred to in the context of its health effects. According to the World Health Organization (WHO), "tobacco" can also refer to any product prepared from the leaf of the tobacco plant for smoking, sucking, chewing or snuffing.

Tobacco use is a major risk factor for a number of diseases, including cancer, heart disease, stroke, lung disease, and various other medical conditions. The smoke produced by burning tobacco contains thousands of chemicals, many of which are toxic and can cause serious health problems. Nicotine, one of the primary active constituents in tobacco, is highly addictive and can lead to dependence.

Angiosperms, also known as flowering plants, are a group of plants that produce seeds enclosed within an ovary. The term "angiosperm" comes from the Greek words "angeion," meaning "case" or "capsule," and "sperma," meaning "seed." This group includes the majority of plant species, with over 300,000 known species.

Angiosperms are characterized by their reproductive structures, which consist of flowers. The flower contains male and female reproductive organs, including stamens (which produce pollen) and carpels (which contain the ovules). After fertilization, the ovule develops into a seed, while the ovary matures into a fruit, which provides protection and nutrition for the developing embryo.

Angiosperms are further divided into two main groups: monocots and eudicots. Monocots have one cotyledon or embryonic leaf, while eudicots have two. Examples of monocots include grasses, lilies, and orchids, while examples of eudicots include roses, sunflowers, and legumes.

Angiosperms are ecologically and economically important, providing food, shelter, and other resources for many organisms, including humans. They have evolved a wide range of adaptations to different environments, from the desert to the ocean floor, making them one of the most diverse and successful groups of plants on Earth.

I apologize for any confusion, but "Meliaceae" is not a medical term. It is a taxonomic category in botany, referring to the Mahogany family of plants, which includes around 50 genera and over 1,300 species of trees and shrubs. Some of these plants have medicinal properties, but "Meliaceae" itself does not have a medical definition.

Phytotherapy is the use of extracts of natural origin, especially plants or plant parts, for therapeutic purposes. It is also known as herbal medicine and is a traditional practice in many cultures. The active compounds in these plant extracts are believed to have various medicinal properties, such as anti-inflammatory, analgesic, or sedative effects. Practitioners of phytotherapy may use the whole plant, dried parts, or concentrated extracts to prepare teas, capsules, tinctures, or ointments for therapeutic use. It is important to note that the effectiveness and safety of phytotherapy are not always supported by scientific evidence, and it should be used with caution and preferably under the guidance of a healthcare professional.

I apologize for the confusion, but "Plant Epidermis" is not a medical term. Instead, it is a term used in botany to describe the outermost layer of cells in plant tissues. The epidermis serves as a protective barrier for the plant, regulating gas exchange and water loss through stomata, and producing cutin, a waxy substance that helps prevent water loss.

In summary, "Plant Epidermis" is a term related to plant biology and not medicine.

Stomata are microscopic pores found in the epidermis of plant leaves, stems, and other organs. They are essential for gas exchange between the plant and the atmosphere, allowing the uptake of carbon dioxide for photosynthesis and the release of oxygen. Plant stomata consist of two guard cells that surround and regulate the size of the pore. The opening and closing of the stomatal pore are influenced by environmental factors such as light, humidity, and temperature, as well as internal signals within the plant.

I apologize for any confusion, but "Pinus" is not a medical term. It is the genus name for a group of plants commonly known as pine trees, which belong to the family Pinaceae in the kingdom Plantae. These evergreen coniferous resinous trees are widely distributed throughout the Northern Hemisphere, with some species also found in the Southern Hemisphere.
