For 96 Moles and millimoles example, one hundred 1p coins weigh 356 g; it is quicker to weigh 356g of 1p coins than to count a hundred coins. Now consider a single molecule of sodium chloride (NaCl) which consists of one sodium ion (Na+) and one chloride ion (Cl–). NaCl = molecule Na+ Cl– = ions Since moles can refer to ions as well as molecules, it can be seen that one mole of sodium chloride contains one mole of sodium ions and one mole of chloride ions. From tables (see the end of this section), the relative ionic masses are: sodium (Na) 23 chloride (Cl) 35. The ‘2’ after the ‘Cl’ means two ions of chlorine: CaCl2 = molecule Ca2+ Cl– +Cl– = ions The molecular mass of calcium chloride is 147. The reason why the molecular mass does not always equal the sum of the atomic masses of the individual ions is because water forms a part of each calcium chloride molecule. From the molecular formula and knowledge of the atomic weights it can be seen that calcium chloride contains: 1moleofCa=40g 2 moles of Cl = 71g 2 moles of H2O, each mole of water = 18g; 2 × 18 = 36g What are moles and millimoles 97 So adding everything together: (40 + 71 +36) = 147 i. One millimole is equal to one- thousandth of a mole One micromole is equal to one- thousandth of a millimole It follows that: 1 mole contains1,000 millimoles (mmol) 1 millimole contains1,000 micromoles (mcmol) So, in the above explanation, you can substitute millimoles for moles and 98 Moles and millimoles milligrams for grams. For our purposes: Sodium chloride would give sodium + chloride 1 mole or 1 mole or 1 mole or 1 millimole 1 millimole 1 millimole 58. It is unlikely that you will encounter these types of calculations on the ward, but it is useful to know how they are done and they can be used for reference if necessary. So it follows that the amount (in milligrams) equal to 1 millimole of sodium chloride will give 1 millimole of sodium. In this case, calculate the total amount (in milligrams) of sodium chloride and convert this to millimoles to find out the number of millimoles of sodium. Calculations involving moles and millimoles 99 So 1 millimole of sodium chloride (NaCl) will weigh 58. First work out the number of millimoles for 1 mg of sodium chloride, and then the number for the total amount. Alternatively, a formula can be used: mg/mL total number of millimoles = × volume(mL) mg of substtance containing 1mmol where, in this case mg/mL = 1. Conversion of percentage strength (% w/v) to millimoles Sometimes it may be necessary to convert percentage strength to the number of millimoles.

The life cycle of the malaria parasite in the host, from merozoite invasion of red blood cells to schizont rupture (merozoite ring stage trophozoite schizont merozoites). The level of asexual parasitaemia determined by microscopy can be expressed in several ways: the percentage of infected red blood cells, the number of infected red cells per unit volume of blood, the number of parasites seen in one feld on high power microscopy examination of a thick blood flm, or the number of parasites seen per 200–1000 white blood cells on high-power examination of a thick blood flm. A combination of two or more classes of antimalarial drug with unrelated mechanisms of action. The ability of a parasite strain to survive and/or to multiply despite the administration and absorption of a drug given in doses equal to or higher than those usually recommended, provided the exposure is adequate. Resistance to antimalarial agents arises because of the selection of parasites with genetic changes (mutations or gene amplifcations) that confer reduced susceptibility. The sexual stages of malaria parasites that infect anopheline mosquitoes when taken up during a blood meal. A combination in which two antimalarial drugs are formulated together in the same tablet, capsule, powder, suspension or granule. A high density of parasites in the blood, which increases the risk of deterioration to severe malaria (although the risk varies in different endemic areas according to the level of transmission) and of subsequent treatment failure. In this document, the term is used to refer to a parasite density > 4% (~ 200 000/ µL). A dark-brown granular material formed by malaria parasites as a by-product of haemoglobin digestion. It may also be phagocytosed by monocytes, macrophages and polymorphonuclear neutrophils. Parasite released into the host bloodstream when a hepatic or erythrocytic schizont bursts. Antimalarial treatment with a single medicine: either a single active compound or a synergistic combination of two compounds with related mechanisms of action.
Ford, 44 years: Giardiasis is a common cause of chronic diarrhoea in adults, and may be difficult to diagnose on stools. If intrathecal therapy is required, it should be administered by someone very experienced in this technique. The average daily dietary calcium intake in adults age 50 and older is 600 to 700 mg per day.

Some clini- cians prefer to frame psychoeducational discussions in everyday terms and use the patient’s own language to negotiate a shared understanding of the major areas of difficulty without turning to a text or manual.

Sigmor, 38 years: Originally referred to as “methadone treatment programs,” these treatment facilities were created to provide special management of the medical and legal issues associated with the use of this potent, long-acting opioid. These strategies engage the parasympathetic nervous system, the “rest and digest” response that slows many high-energy body functions, as opposed to the “fight or flight” response of the sympathetic nervous system, which increase heart rate, blood pressure, and other reflexes in response to a perceived threat. Additional ivermectin treatment on days 22 and likely poses a low risk to pregnant women and is likely 29 might be required for severe cases (864).
Iomar, 54 years: Studies show that among patients with heart failure, those who take digoxin may go to the hospital less often than patients who are not taking this type of medicine. Patients who are heavy but not obese require the same mg/kg bw doses as lighter patients. The decision to recommend antimalarial drugs for general use depends on the strength of the evidence for safety and effcacy and the context of use.
