Antibiotics fight off bacteria by (a) inhibiting the bacteria’s ability to make protein called protein synthesis 30mg nimotop free shipping. What chemical mediators bring about the inflammatory reaction by vaso- dilatation discount nimotop 30mg on-line, relaxing smooth muscles, making capillaries permeable, and sensitizing nerve cells within the affected area to pain? The patient’s white blood count should be studied after the patient is given an antibiotic. Chicken soup is not a drug but it does contain a mucous-thinning amino acid called cysteine and is considered “grandma’s remedy” for the common cold. Actually, time is the best cure and most people feel better in 7 to 10 days with or without chicken soup. The common cold is one of a number of respiratory diseases that can infect our body. However, some respiratory dis- eases—such as emphysema—are debilitating and can slowly choke the life out of a person. In this chapter, we’ll explore the more common respiratory diseases and learn about the medications that are used to either destroy the disease-causing microorganism or to manage the symptoms of the disease. A Brief Look at Respiration Before learning about respiratory diseases and the medications used to treat them, let’s take a few moments to briefly review the anatomy and physiology of the res- piratory tract. The upper respiratory tract contains the nares, nasal cavity, pharynx, and larynx and the lower tract consists of the trachea, bronchi, bronchioles, alveoli, and alveolar- capillary membrane. During respiration, air is inhaled and makes its way through the upper respi- ratory tract and travels to the alveoli capillary membrane in the lower respiratory tract, which is the site of gas exchange. Oxygen from the air attaches to the hemoglobin of the blood while carbon dioxide leaves the blood and is expelled through the lower and upper respiratory tracts during expiration. Perfusion Perfusion is when blood from the pulmonary circulation is sufficient at the alveolar-capillary bed to conduct diffusion. In order for perfusion to occur, the alveolar pressure must be matched by adequate ventilation. The presence of mucosal edema, secretions and bronchospasm increase resistance to the airflow, which results in decreased ventilation. Diffusion Diffusion is the process where oxygen moves into the capillary bed and carbon dioxide leaves the capillary bed. Compliance is the ability of the lungs to be distended and is expressed as a change in volume per unit change in pressure. These are the connective tis- sue that consists of collagen and elastin and surface tension in the alveoli, which is controlled by surfactant. Surfactant is a substance that lowers surface tension in the alveoli, thereby preventing interstitial fluid from entering the alveoli. That is, the lungs become stiff requiring more-than-normal pressure to expand the lungs. This is typically caused by an increase in connective tissue or an increase in surface tension in the alveoli. Throughout the body chemoreceptors sense the concentration of oxygen, car- bon, and carbon dioxide and then send a message to the central chemoreceptors located in the medulla near the respiratory center of the brain and through cere- brospinal fluid to respond to changes. When an increase in carbon dioxide is detected and there is an increase in hydrogen ions, the message goes out to increase ventilation. Once the oxygen pressure falls below <60 mmHg, the peripheral chemoreceptors send a message to the respiratory center in the medulla to increase ventilation. The tracheobronchial tube is a fibrous spiral of smooth muscles that become more closely spaced as they near the terminal bronchioles. The size of the air- way can be increased or decreased by relaxing or contracting the bronchial smooth muscle. This is controlled by the parasympathetic nervous system—par- ticularly the vagus nerve. The vagus nerve releases acetylcholine when it is stimulated, which causes the tracheobronchial tube to contract. The opposite effect is created when the sympathetic nervous system releases epi- nephrine that stimulates the beta2 receptor in the bronchial smooth muscle. In a healthy patient the sympathetic and parasympathetic nervous systems counter- balance each other to maintain homeostasis. Upper Respiratory Tract Disorders Respiratory disorders are divided into two groups: upper respiratory tract disorders and lower respiratory tract disorders. These include the common cold, acute rhinitis (not the same as allergic rhinitis), sinusitis, acute tonsillitis, and acute laryngitis. The rhinovirus is frequently accompanied by acute inflammation of the mucous membranes of the nose and increased nasal secretions. The rhinovirus is seasonable: 50% of the infections occur in the winter and 25% dur- ing the summer.

Primarily a disease of the rural poor in Africa, Plas- modium falciparum malaria causes more deaths than any other infectious agent in young African children and is responsible for almost 40% of these deaths. The efficacy of such remedies has been demonstrated by the successful development of modern antimalarials from traditionally used Cinchona and Artemisia spp. Twenty years later, Africa’s fragile oral knowledge systems are threatened by war, famine, political instability and urbanisation (with concomitant loss of the ‘ecosystem generation’). Unsustainable harvesting practices, delib- erate habitat destruction and climate change threaten the survival of the plant species on which Africa’s traditional healers depend. The greatest threat to traditional medical practice, however, is the burgeoning global population, whose growth and consumption of natural resources places plant diversity at risk in most parts of the world. The quantity of wild plant material exported from Africa and destined for the international pharma- ceutical trade is enormous, but pales into insignificance compared with that required by the trade in crude drugs used in traditional medical practice, within individual states or across regional borders. This has resulted in a disregard for traditional conservation practices and ‘an opportunistic scramble for the last bag of bark, bulbs or roots’. High rates of unemployment and low levels of formal education have also given rise to an increasing number of medicinal plant vendors, plying their trade in the marketplace (Figure 5. The period 2001–10 has been declared the Decade of African Traditional Medicine and an Africa Health Strategy (2007–15) has been formulated, focusing on the strengthening of health systems for equity and development in Africa. Conclusion There is no doubt that Africa’s rich botanical biodiversity and well-estab- lished traditional medical systems can be harnessed for the provision of better healthcare throughout the continent. The neces- sary expertise and infrastructure do not exceed the capabilities of the average African university School of Pharmacy.
