Body secretions

Mar f body secretions contain substances that exert abacteriddal action, for example the enzyme lysozyme which is found in tears, nasal secretions and saliva hydrochloric acid in the stomach which results in a low pH and basic polypeptides such as spermine which are found in semen. [Pg.280]

Effect on secretions Atropine reduces the various body secretions e.g. sweat, salivary, bronchial and lacrimal etc. It also reduces the volume and total acidity of gastric secretion and, reduce the secretion of mucin and enzymes in the gastric secretions induced by cholinergic drugs. [Pg.163]

TMA accumulates in urine, sweat and other body secretions of affected individuals. It may occur in the breath and being volatile it is readily released into the atmosphere. [Pg.783]

All burnt comeal stroma show lower osmolarity due to the loss of ions by continuous rinsing. The higher osmolar Diphoterine adds some ions to the burnt corneal stroma, but its osmolarity is still much lower than the one of the aqueous humor. It is obvious that there is no change in osmolarity in aqeous humor in healthy and in burnt eyes due to autoregulation of this milien by the ciliary body secretion. The considerable differences in tissue osmolarity indicate that there will be a strong fluid uptake into the comeal tissue, resluting in opacity. This indicates a severe water uptake and a lack of the endothelial pumping function. [Pg.79]

Polysaccharide chains in the peptidoglycan layer (Fig. 8-29) of the cell walls of bacteria are attacked and cleaved by lysozymes,55 enzymes that occur in tears and other body secretions and in large amounts in egg white. Some bacteria and fungi, and even viruses, contain lysozymes.56 Their function is usually to protect against bacteria, but lysozyme of phage T4 is a component of the baseplate of the virus tail (Box 7-C). [Pg.599]

Body odor is due to the formation of certain chemicals by the action of skin bacteria on the natural body secretions that are a part of perspiration. [Pg.39]

Calcium is critical to your diet as you grow older. It may be too late for it to do much for your teeth, but you should do what you can to maintain strong bones. If you don t get enough calcium, the body secretes a hormone that causes the needed calcium to be taken from your bones. This process, called demineralization, causes bones to become porous. The medical word for this is osteoporosis. [Pg.119]

The ciliary body, situated posterior to the iris, performs several functions. It connects the anterior part of the choroid to the circumference of the iris, and contains the ciliary muscles necessary for accommodation. The ciliary body secretes aqueous humor into the posterior together with nutrients to nourish the lens. In the ciliary body, melanin is located only in the outer pigmented epithelium [24]. Aqueous humor is actively secreted and passively filtered by the ciliary body. Although the rate of secretion is about 2 pL/min the same volume is drawn-off via Schlemm s canal from where it is conducted into veins [25]. [Pg.481]

Vertebrate immune systems are capable of producing antibodies to a greater or lesser degree in response to the presence of a foreign protein within the tissues of the animal. The presence of the foreign protein initiates a sequence of events, mediated by the cells of the immune system that lead to the release of antibody molecules in blood and some body secretions. [Pg.170]

We previously demonstrated that application of a negative electric potential on the skin surface affects the ion gradient in the epidermis and accelerates lamellar body secretion and skin barrier recovery.7... [Pg.156]

Most cells in the body secrete chemicals that act locally, that is, they act on cells in their immediate environment. These chemical signals are rapidly destroyed or removed thus, they do not enter the blood and are not distributed throughout the body. Histamine (see p. 420) and prostaglandins (see p. 419) are examples of local mediators. [Pg.42]

As its name implies, epidemic keratoconjunctivitis (EKC) is highly contagious and communicable. It is typically caused by adenoviruses, with types 8, 19, and 37 most commonly reported. Adenoviruses can cause severe epidemics and can be spread by finger-to-eye contact, medical instruments such as tonometers, and possibly chairs, magazines, and other articles found in the practitioner s reception area.The contagious period may last as long as 3 weeks, and the virus is recoverable from all body secretions the first 10 days after ocular involvement occurs. [Pg.525]

In their physiological action atropine and hyoscyamine are similar and exert what is termed a mydriatic action causing dilation of the pupil of the eye. This action may be produced eithef by external application or by taking internally. As little as i part atropine in 130,000 parts of water will exert a distinct action on the eye. They decrease body secretions and also affect the heart. Taken internally they are poisonous in as little as o.i gm. Tropine exerts no mydriatic action when applied to the eye but in large doses internally it does produce dilation. In addition to the use of these alkaloids in the pure form, extracts of belladonna are also used. [Pg.894]

Acute viral hepatitis B can present with up to 10 viruses per millilitre of blood - indeed an inconceivably high figure. The typical maximum titre is about 10 viruses/ml serum. It is possible to detect 10 -10 particles by means of HBV DNA. A very small number of viruses suffices for an infection in the individual case. The PCR method identifies a very low number of HBV particles, although in practice the detection threshold of 100 to 1,000 HBV particles/ml is considered adequate. With such excessive viraemia, it must be assumed that B viruses pass into all body secretions and excretions -only their detection in the stools remains controversial. Sperm is considered to be particularly infectious. (191, 199, 221, 231) (s. tab. 22.4)... [Pg.426]

Body secretions HCV antibodies and HCV RNA could be detected in saliva, sweat, urine, ascites, ejaculate, breast milk, bile and lacrimal fluid. It can be assumed that (as with hepatitis B) the occurrence of HCV in various body fluids is directly correlated to the HCV concentration in the serum. (268, 290, 330, 338, 343)... [Pg.441]

Nonessential staff or visitors must not enter the room of suspected VHP patients. The facility should maintain a log of all approved visitors entering the room. Close personal contacts or medical personnel exposed to blood or body secretions from VHP patients require monitoring for fever or other symptoms during the established incubation period. [Pg.101]

Avoid direct contact with victim or body secretions [9] ... [Pg.70]

The amount of hepatic and site specific IGF-1 the body secretes is dependent upon insulin management. [Pg.95]
