Corpus Luteum

A temporary endocrine gland formed at ovulation from part of the former egg follicle, and the source of progesterone. See PROGESTERONE, ESTROGEN, MENOPAUSE... corpus luteum

Luteinizing Hormone

(LH) This is a sugar-bearing protein manufactured by the anterior pituitary. Like a lot of the pituitary hormones, it surges on and off, since constant secretion would overload and deaden receptors. In women, it builds up after menses, stimulating the release of estrogen from the ovaries. Estrogen in turn stimulates the hypothalamus to increase its stimulation of LH from the pituitary, until, a day or two before ovulation, they produce a guitar-amp feedback, and the cells that produce LH start to surge follicle-stimulating hormone (FSH). The egg pops, being replaced by the corpus luteum, which produces progesterone for the next eleven to twelve days. Progesterone inhibits and lowers LH levels, as well as inhibiting levels of estrogen already being produced by the young follicles that will produce next month’s egg. In men, LH is responsible for stimulation of testosterone, although FSH and the testes hormone inhibin are responsible for both the production of sperm and controlling testosterone.... luteinizing hormone

Luteinizing-hormone Releasing Hormone

(LH-RH) The same substance as Follicle-Stimulating-Hormone Releasing Hormone (FSH-RH), both of which are actually Gonadotrophin-Releasing Hormone (GnRH or GRH). Confused? Imagine being an endocrinologist 20 years ago. These (This) are (is) a peptide secreted into the little portal system that drains from the hypothalamus to the pituitary. If it is surged hourly and not too strongly, the pituitary secretes LH and the ovaries secrete estrogen. If it is surged hourly and strongly, the estrogens rise drastically, the pituitary secretes FSH, you pop an egg, start the corpus luteum and begin progesterone secretion. The surge is now slowed to every four or five hours, not too strongly, and the pituitary secretes LH every four or five hours...and the ovaries make progesterone. The same hypothalamic hormone triggers different pituitary responses based on AMPLITUDE and FREQUENCY.... luteinizing-hormone releasing hormone

Colchicum Luteum

Baker.

Family: Liliaceae.

Habitat: The temperate Himalayas from Kashmir to Chamba. Major supplies of the drug are received from Kashmir.

English: Hermodactyls, Colchicum, Meadow Saffron, Golden Collyrium (Indian substitute). (C. luteum is a good substitute for C. autumnale L. which is official in the B.P.)

Ayurvedic: Hiranyatuttha.

Unani: Suranjaan Talkh.

Action: Non-steroidal antiinflammatory, anti-gout (relieves inflammation and pain of acute gout but does not increase expulsion of uric acid, is used with an alkaline diuretic), emetic, cathartic. Anti-chemotactic, antiphlogistic, inhibitor of mitosis. Highly toxic. Used for external application to lessen inflammation and pain.

Key application: In acute gout attack. (German Commission E.)

The fresh corms and aerial parts of a sample from Jammu yielded 0.94% and 070% of total alkaloids, the major being colchicine 0.40% and 0.20% respectively. Colchicine analogs— decteyl thiocolchicine (DTC), decetyl- methylcolchicine (DMC) and tri- methylcolchicinic acid (TMCA) were effective in the treatment of gout; DTC may elicit agranulocytosis.

Colchicine binds to tubulin, the protein subunit of microtubules. Its most important biological effect is the inhibition of processes that depend upon microtubule function by blocking polymerization. In preventing micro- tubule formation, colchicine has been shown to inhibit catecholamine secretion from adrenal medulla, iodine secretion from thyroid gland and pro- lactin secretion from pituitary tumour cells. It inhibits stimulated insulin secretion from isolated perfused pancreas and islets in vitro.

The use of Colchicum for long periods is not recommended owing to its toxicity in larger doses (even 7 mg of colchicine has caused death) and its depressant action upon central nervous system.

Prolonged use of Colchicum autum- nale may cause agranulocytosis, aplas- tic anaemia and peripheral nerve inflammation. (Sharon M. Herr.)... colchicum luteum

Gnaphalium Luteo-album

Linn.

Family: Asteraceae.

Habitat: Throughout India, ascending up to 3,350 m in the Himalayas.

English: Jersey Cudweed, Cotton Weed, Cat's Foot, Everlasting Flower.

Folk: Bal-raksha.

Action: Leaves—astringent, haemostatic, vulnerary. The tomentum is applied as counter- irritant in gout, also used as tinder.... gnaphalium luteo-album

Luteinising Hormone

A hormone secreted by the anterior PITUITARY GLAND which stimulates OVULATION, maturation of the CORPUS LUTEUM, and the synthesis of progesterone by the ovary (see OVARIES) and testosterone by the testis (see TESTICLE).... luteinising hormone

Luteinising Hormone-releasing Hormone (lhrh)

A natural hormone released by the HYPOTHALAMUS gland in the BRAIN. It stimulates the release of GONADOTROPHINS from the PITUITARY GLAND; these control the production of the sex hormones (see ANDROGEN; OESTROGENS).... luteinising hormone-releasing hormone (lhrh)

Luteal Cyst

see ovarian cyst.... luteal cyst

Lutein

n. 1. a yellow carotenoid pigment and potent *antioxidant found in many vegetables. Like the related pigment zeaxanthin (see also mesozeaxanthin), it occurs in high concentrations in the human eye. For this reason these pigments are thought to be crucial to healthy vision. 2. the yellow pigment of the corpus luteum.... lutein

Luteo

combining form denoting 1. yellow. 2. the corpus luteum.... luteo

Luteotrophic Hormone

(luteotrophin) see prolactin.... luteotrophic hormone

Reseda Luteola

Linn.

Family: Resedaccae.

Habitat: Indigenous to western Europe; grown in gardens in India.

English: Dyer's Rocket, Weld.

Action: Plant—diuretic, diaphoretic, anthelmintic.

A luteolin glucoside, luteoloside, has been isolated from the fresh blossoms and outer parts of the plant. It has a low toxicity and mild influence on capillary resistance and possesses diuretic properties.

Reseda odorata Linn., known as Mignonette, is indigenous to North Africa and cultivated in gardens in India.

The herb is reported to allay irritation and ease pains. The seeds are applied externally as a resolvent. The... reseda luteola
