| oxytocia | Rapid parturition. Origin: G. Okytokos, swift birth (05 Mar 2000) |
| oxytocic | 1. Pertaining to, characterised by or promoting oxytocia (= rapid labour). 2. An agent that hastens evacuation of the uterus by stimulating contractions of the myometrium. (18 Nov 1997) |
| oxytocics | Drugs that stimulate contraction of the myometrium. They are used to induce labour at term, to prevent or control postpartum or postabortion haemorrhage, and to assess foetal status in high risk pregnancies. They may also be used alone or with other drugs to induce abortions (abortifacients). Oxytocics used clinically include the neurohypophyseal hormone oxytocin and certain prostaglandins and ergot alkaloids. (12 Dec 1998) |
| oxytocin | <protein> A peptide hormone (1007 D) from hypothalamus: transported to the posterior lobe of the pituitary (see neurophysin). Induces smooth muscle contraction in uterus and mammary glands. Related to vasopressin. (18 Nov 1997) |
| oxytocinase | <enzyme> Registry number: EC 3.4.11.3 (12 Dec 1998) |
| oxytricha | A genus of ciliate protozoa having a unique cursorial type of locomotion. (12 Dec 1998) |
| oxyuriasis | Small nematode, Enterobius vermicularis, that is responsible for intestinal infection in humans. It appears as a small thread-like worm approximately 3-5mm in length. Common symptoms include anal itching that is worse at night when the female worm migrates to the anus to lay its eggs. Thin, white, thread-like worms may be visible at the anal opening or in the stools. The tape test can be performed by placing the sticky side of the tape across the anal opening for several seconds. The tape is then transferred to a glass slide where eggs may be seen through the microscope. (27 Sep 1997) |
| oxyuricide | An agent that destroys pinworms. Origin: oxyurid + L. Caedo, to kill (05 Mar 2000) |
| oxyurid | Common name for members of the family Oxyuridae. Origin: see Oxyuris (05 Mar 2000) |
| oxyurida | An order of nematodes of the subclass secernentea. Its organisms are characterised by a single, ventral excretory gland and a relatively stout, short body. (12 Dec 1998) |
| oxyurida infections | Infections with nematodes of the order oxyurida. (12 Dec 1998) |
| Oxyuridae | A family of parasitic nematodes (superfamily Oxyuroidea) found in the large intestine or caecum of vertebrates and the intestine of invertebrates, especially insects and millipedes; it includes the genera Aspiculurus, Enterobius, Oxyuris, Passalurus, Syphacia, and Thelandros. (05 Mar 2000) |
| oxyuris | A group of intestinal worms that includes pinworm. (12 Dec 1998) |
| oxyuroidea | A superfamily of parasitic nematodes consisting of several genera. Enterobius, which occurs in humans, and oxyuris, which occurs in horses, are two of the most common. Other genera are: skrjabinema, passalurus, dermatoxys, and probstmayria. (12 Dec 1998) |
| oxycephaly |
Turricephaly. A small "tower" shaped skull produced by craniosynostosis (premature fusion of skull sutures) involving all sutures. There is a high vertical index (height of skull divided by length of skull).
