Cordyline terminalis

Description: The ti has unbranched stems with straplike leaves often clustered at the tip of the stem. The leaves vary in color and may be green or reddish. The flowers grow at the plant’s top in large, plumelike clusters. The ti may grow up to 4.5 meters tall.

Habitat and Distribution: Look for this plant at the margins of forests or near homesites in tropical areas. It is native to the Far East but is now widely planted in tropical areas worldwide.

Edible Parts: The roots and very tender young leaves are good survival food. Boil or bake the short, stout roots found at the base of the plant. They are a valuable source of starch. Boil the very young leaves to eat. You can use the leaves to wrap other food to cook over coals or to steam.

Other Uses: Use the leaves to cover shelters or to make a rain cloak. Cut the leaves into liners for shoes; this works especially well if you have a blister. Fashion temporary sandals from the ti leaves. The terminal leaf, if not completely unfurled, can be used as a sterile bandage. Cut the leaves into strips, then braid the strips into rope.

Connective Tissue

Sometimes called ?brous tissue, this is one of the most abundant tissues in the body, holding together the body’s many di?erent structures. Connective tissue comprises a matrix of substances called mucopolysaccharides in which are embedded various specialist tissues and cells. These include elastic (yellow), collagenous (white) and reticular ?bres as well as macrophages (see MACROPHAGE) and MAST CELLS. Assembled in di?ering proportions, this provides structures with varying functions: bone, cartilage, tendons, ligaments and fatty and elastic tissues. Collagenous connective tissue binds the muscles together and provides the substance of skin. It is also laid down in wound repair, forming the scar tissue. Contracting with time, connective tissue becomes denser, causing the puckering that is typical in serious wounds or burns. (See ADHESION; SCAR; WOUNDS.)... connective tissue

Tinea

Also called ringworm. Refers to a variety of superficial fungal infections of the skin on different areas of the body caused by dermatphyte fungi belonging to the genera Epidemophytum, Microsporosum, and Trichophytum..... tinea

Adipose Tissue

Adipose tissue, or fat, is a loose variety of ?brous tissue in the meshes of which lie cells, each of which is distended by several small drops, or one large drop, of fat. This tissue replaces ?brous tissue when the amount of food taken is in excess of the bodily requirements. Adipose tissue occurs as a layer beneath the skin and also around several internal organs. (See DIET; FAT; OBESITY.)... adipose tissue

Tibia

The larger of the two bones in the leg. One surface of the tibia lies immediately beneath the skin in front, forming the shin; fractures of this bone are usually compound ones. The thigh bone abuts on the larger upper end of the tibia at the knee-joint, whilst below, the tibia and ?bula together enter into the ankle-joint, the two bosses or malleoli at the ankle belonging, the inner to the tibia, the outer to the ?bula.... tibia

Tinnitus

A noise heard in the EAR without any external cause. It often accompanies DEAFNESS, and severely deaf patients ?nd tinnitus as troubling as – if not more so than – the deafness. Tinnitus is described as ‘objective’ if it is produced by sound generated within the body by vascular tumours or abnormal blood ?ows. In patients with conductive hearing loss, tinnitus may be the consequence of the blocking of outside noises so that their own bodily activities become audible. Even normal people occasionally suffer from tinnitus, but rarely at a level which prompts them to seek medical advice. Present knowledge of the neurophysiological mechanisms is that the noise ‘arises’ high in the central nervous system in the subcortical regions of the BRAIN.

The resting level of spontaneous neuronal activity in the hearing system is only just below that at which sound enters a person’s consciousness – a consequence of the ?ne-tuning of normal hearing; so it is not, perhaps, surprising that normally ‘unheard’ neuronal activity becomes audible. If a patient suffers sensorineural deafness, the body may ‘reset’ the awareness threshold of neural activity, with the brain attempting greater sensitivity in an e?ort to overcome the deafness. The condition has a strong emotional element and its management calls for a psychological approach to help sufferers cope with what are, in e?ect, physically untreatable symptoms. They should be reassured that tinnitus is not a signal of an impending stroke or of a disorder of the brain. COGNITIVE BEHAVIOUR THERAPY can be valuable in coping with the unwanted noise. Traditionally, masking sounds, generated by an electrical device in the ear, were used to help tinnitus sufferers by, in e?ect, making the tinnitus inaudible. Even with the introduction of psychological retraining treatment, these maskers may still be helpful; the masking-noise volume, however, should be kept as low as possible or it will interfere with the retraining process. For patients with very troublesome tinnitus, lengthy counselling and retraining courses may be required. Surgery is not recommended.

Under the auspices of the Royal National Institute for Deaf People, the RNID Tinnitus Helpline has been established. Calls are charged at local rates. (See also MENIÈRE’S DISEASE.)... tinnitus

Tissue Typing

The essential procedure for matching the tissue of a recipient in need of transplanted tissue or organ to that of a potential donor. Unless there is a reasonable match, the recipient’s immune system (see IMMUNITY) will reject the donor’s organ. The main factors that are relevant to an individual’s reaction to donor tissue are called histocompatability antigens (see ANTIGEN). These are mostly human leucocyte antigens (HLAs – see HLA SYSTEM) present on the surface of cells. HLAs are inherited and, like ?ngerprints, unique to an individual, although identical twins have identical HLAs and hence are perfect matches for TRANSPLANTATION procedures.... tissue typing

Carthamus Tinctorius

Linn.

Family: Asteraceae.

Habitat: Cultivated mainly as an oil-seed crop in Madhya Pradesh, Maharashtra.

English: Safflower.

Ayurvedic: Kusumbha, Vahin- shikhaa, Vastraranjaka, Kusum.

Unani: Qurtum.

Siddha/Tamil: Chendurakam.

Action: Oil—aids prevention of arteriosclerosis, coronary heart disease and kidney disorders as a polyunsaturated fat. Flowers— stimulant, sedative, diuretic, emmenagogue; used in fevers and eruptive skin conditions, measles.

Charred safflower oil is used in rheumatism and for healing sores.

Key application: Dried flowers— in cardiovascular diseases, amen- orrhoea, dysmenorrhoea and retention of lochia; also in wounds and sores with pain and swelling. (Pharmocopoeia of the People's Republic of China, 1997.)

Safflower contains carthamone, lig- nans and a polysaccharide. The polysaccharide, composed of xylose, fructose, galactose, glucose, arabinose, rhamnose and uronic acid residues, stimulates immune function in mice. It induced antibody formation in mice following peritoneal injection. Extracts of flowers have also been tested in China on blood coagulation, where a prolongation of clothing time was observed and platelet aggregation inhibited. Chinese research indicates that Safflower flowers can reduce coronary artery disease, and lower cholesterol levels. Flowers and seeds exhibit lipase activity. The flower extract also exhibited anti-inflammatory, sedative and analgesic effect and inhibitory effect on spontaneous motor activity.

The plant contains a propanetriol derivative, which can be used for the treatment of circulatory disorders.

Recent research suggests that improving the lipid profile might not be as important to reducing the risk of cardiovascular disease as suggested. (Natural Medicines Comprehensive Database, 2007.)

Safflower is contraindicated in pregnancy, gastric disorders, excessive menstruation, haemorrhagic diseases.

Wild and thorny Safflower, growing in the arid tract of Haryana and Punjab (locally known as Kantiaari, Poli, Poiyan) is equated with C. oxy- cantha Bieb. The plant is diuretic.

Medial Tibial Syndrome

The term applied by athletes to a condition characterised by pain over the inner border of the shin, which occurs in most runners and sometimes in joggers. The syndrome, also known as shin splints, is due to muscular swelling resulting in inadequate blood supply in the muscle: hence the pain. The disorder may be the result of compartment syndrome (build-up of pressure in the muscles), TENDINITIS, muscle or bone in?ammation, or damage to the muscle. It usually disappears within a few weeks, responding to rest and PHYSIOTHERAPY, with or without injections. In some cases, however, it becomes chronic and so severe that it occurs even at rest. If the cause is the compartment syndrome, relief is usually obtained by a simple operation to relieve the pressure in the affected muscles.... medial tibial syndrome

Hin,

Ben: Giloe;

Mal: Amritu, Chittamritu;

Tam: Amridavalli

Kan: Amritaballi;

Tel: Tivantika, Tippatige; Pun: Batindu Ori: Gulochi

Importance: Tinospora is a common climbing shrub which is used in medicine, usually in the fresh state, though it is commercially available in the dried state. It is probably the most useful preparation acting as a tonic and aphrodisiac. As a tonic it is best given in infusion with or without milk. It is a popular remedy for snake-bite and leprosy. It is generally prescribed in general debility, diabetes, fever, jaundice, skin diseases, rheumatism, urinary diseases, dyspepsia, gout, gonorrhoea and leucorrhoea. It is a constituent of several preparations like guduchayado churna, gududyadi kwath, guduchilouha, amritarista, sanjivanivati, guduchi taila, amiritastak kwath, etc. The juice mixed with the pulp of long pepper and honey is a house hold remedy for gonorrhoea. Several oils for external applications are prepared with amrita and applied to skin diseases, rheumatic affections and other nervous complaints. A small quantity of bruised stem soaked for three hours in half a litre of water and strained combined with ammonium acetate is administered in intermittent and milder forms of fevers. It is rendered more agreeable with cinnamon, cloves and other aromatics. (Viswanathan, 1997).

Distribution: The plant is widely seen in tropical countries like India, Myanmar, Sri Lanka and in Andaman Islands. It is mostly found trailing on forest trees, fences and hedges along the boundaries.

Botany: Tinospora cordifolia (Willd) Miers ex Hk. f & Thoms. syn. Menispermum cordifolium Willd, Cocculus cordifolius (Willd) DC. belongs to the family Menispermaceae. It is a climbing shrub with rough corky bark. Leaves are glabrous, cordate 5-10cm broad, acute or accuminate. The plant is dioecious. Male flowers are in fascicles; sepals oval; petals half the length of sepals. Female flowers are usually solitary, having ovary on the fleshy receptacle. Fruits are red when ripe.

Agrotechnology: Giloe requires a warm humid tropical climate. It thrives well in deep fertile soils which are rich in organic matter. It is propagated vegetatively by stem cuttings. About 10-15cm long stem cuttings having at least 2 nodes are planted in the field or polybags. Treatment of cut ends with hormones gives better results. The usual planting time is with the onset of monsoon in May-June. Usually it is planted along boundaries or nearby tall trees and allowed to trail on the trees or hedges and hence regular spacing is not followed. While planting, adequate amounts of organic manure are applied. Once the plant is established no much management is needed. The stem is the most economic part. Harvesting can be commenced after one year and usually partial harvesting is followed depending on the necessity. The stem and root should be collected in hot season when the concentration of the bitter principle is the highest. A full grown well ramified plant may give 2-3kg vines, which are cut into smaller pieces and traded either fresh or after drying.

Properties and activity: The plant contains cordifol, tinosporidine, tinosporide, perberilin, heptacosanol, - sitosterol, cordifolone, tinosporon, tinosporic acid, tinosporol, cordifolide, tinosporine, magnoflorine and tembetarine (Husain et al,1992).

The plant is antigonorrhoric, stomachic, antispasmodic, antiinflammatory, stimulant, diuretic, emetic, antidiabetic, aphrodisiac, antiperiodic, antileprotic antirheumantic and tonic. The root is an emetic in large doses. The tincture and extract are alterative and tonic and in a less degree antiperiodic and diuretic. (Dey,1980).... tinospora

Tissues Of The Body

The simple elements from which the various parts and organs are found to be built. All the body originates from the union of a pair of CELLS, but as growth proceeds the new cells produced from these form tissues of varying character and complexity. It is customary to divide the tissues into ?ve groups:

Epithelial tissues, including the cells covering the skin, those lining the alimentary canal, those forming the secretions of internal organs. (See EPITHELIUM.)

Connective tissues, including ?brous tissue, fat, bone, cartilage. (See under these headings.)

Muscular tissues (see MUSCLE).

Nervous tissues (see NERVE).

Wandering corpuscles of the BLOOD and LYMPH. Many of the organs are formed of a single

one of these tissues, or of one with a very slight admixture of another, such as cartilage, or white ?brous tissue. Other parts of the body that are widely distributed are very simple in structure and consist of two or more simple tissues in varying proportion. Such are blood vessels (see ARTERIES; VEINS), lymphatic vessels (see LYMPHATICS), lymphatic glands (see GLAND), SEROUS MEMBRANES, synovial membranes (see JOINTS), mucous membranes (see MUCOUS MEMBRANE), secreting glands (see GLAND; SALIVARY GLANDS; THYROID GLAND) and SKIN.
