The meaning of the symbols of lisinopril seen in a dream.

The ENZYME that converts angiotensin I to angiotensin II (see ANGIOTENSIN) is called angiotensin-converting enzyme. Angiotensin II controls the blood pressure and is the most potent endogenous pressor substance produced in the body; angiotensin I has no such pressor activity. Inhibition of the enzyme that converts angiotensin I to angiotensin II will thus have marked effects on lowering the blood pressure, and ACE inhibitors have a valuable role in treating heart failure when thiazides and beta blockers cannot be used or fail to work, especially after myocardial infarction (see HEART, DISEASES OF). Captopril was the ?rst ACE inhibitor to be synthesised: it reduces peripheral resistance by causing arteriolar dilatation and thus lowers blood pressure. Other drugs such as enalapril, lisinopril, cilazapril, quinapril and ramipril have since been developed. Some kidney disorders increase the production of angiotensin II and so cause HYPERTENSION.... angiotensin-convertingenzyme (ace) inhibitors

A way of understanding speech by interpreting movements of the mouth and tongue. Lip-reading is often used by people who are deaf.

liquid paraffin A lubricant laxative drug obtained from petroleum. It can cause anal irritation, and prolonged use may impair the absorption of vitamins from the intestine into the blood. lisinopril An ACE inhibitor drug commonly used to treat hypertension. lisp A common speech disorder caused by protrusion of the tongue between the teeth so that the “s” sound is replaced by “th”. Sometimes the cause is a cleft palate (see cleft lip and palate). In most children, there is no physical defect and lisping disappears by the age of about 4. listeriosis An infection that is common in animals and may also affect humans. It is caused by the bacterium LISTERIA MONOCYTOGENES, which is widespread in the environment, especially in soil. Possible sources of human infection include soft cheese, ready-prepared coleslaw and salads, and improperly cooked meat.

In most adults, the only symptoms are fever and aching muscles. There may also be sore throat, conjunctivitis, diarrhoea, and abdominal pain. Pneumonia, septicaemia, and meningitis may develop in severe cases. However, listeriosis can be life-threatening, particularly in elderlypeople, those with reduced immunity, and newborn babies. In pregnant women, infection may cause a miscarriage.

The condition is diagnosed by blood tests and analysis of other body fluids, such as urine. Treatment is with antibiotic drugs, such as ampicillin.... lip-reading
