Viruses reproduce or replicate within cells of the host depend ing on metabolic processes of the host cell order discount albendazole antiviral quiz. They cannot reproduce independent of a host cell because viruses have no meta bolic machinery of their own discount albendazole 400mg with mastercard hiv infection rate in kenya. Replication cycle begins when a virion (viral particle) binds to a receptor site on the plasma membrane of a host cell albendazole 400mg discount stages of hiv infection symptoms. Once bound, the virus releases enzymes weakening the plasma mem brane, allowing penetration of the virus. After viral nucleic acids/proteins (virion compound) are assembled to form a mature virus, it is released from the host cell (budding) for transmission to other host cells, spreading viral infection. Protease inhibitors suppress viral replication by inhibiting protease, an enzyme responsible for cleaving viral precursor polypeptides with mature/infective virions. Intervention/Evaluation: Monitor renal function, fluid status, I/O, sleep and rest patterns, altered nutri tion related to nausea produced by the antivirals. Review results assessing renal/hepatic function and integrity of hemopoietic system. Patient/Family Teaching: Inform pt of importance of immu nization and maintaining immunization against viral infections for small children and adults at high risk of acquiring influenza. Call physician if condition worsens or pt experiences any toxicity with the medication. Intervention/Evaluation: Monitor B/P and apical pulse before giving drug; notify physician before administration if B/P or pulse are not within agreed parameters. Methylxanthines: Directly relax smooth muscle of bronchial airway, pulmonary blood vessels (relieve bronchospasm, increase vital capacity). Beta2-adrenergic agonists: Stimulate beta receptors in lung, relax bronchial smooth muscle, increase vital capacity, decrease airway resistance. Anticholinergics: Inhibit cholinergic receptors on bronchial smooth muscle (block acetylcholine action). Leukotriene receptor antagonist: Blocks effects of leukotriene (bronchoconstriction, inflammation, edema). Antileukotriene: Inhibits enzyme 5-lipoxygenase, reducing production of leukotriene, a bronchoconstrictor. Cimetidine, ciprofloxacin, erythromycin, norfloxacin may increase concentration, toxici ty.

The person 47 Human Anatomy and Physiology who is genetically unable to produce any melanin is an albino order albendazole in india hiv rates of infection in us. Sudoriferous /sweat/ glands Types: Eccrine and Apocrine glands Eccrine glands are small purchase albendazole australia antiviral herpes, simple coiled tubular glands distributed over nearly the entire body buy albendazole with visa acute hiv infection symptoms mayo, and they are absent over nail beds, margins of lips of vulva, tips of penis. The sweat they secret is colorless, aqueous fluid containing neutral fats, albumin, urea, lactic acid and sodium chloride. Apocrine glands are odiferous, found at the armpits, in the dark region around nipples, the outer lips of the vulva, and the anal and genital regions. The female breasts are apocrine glands that have 48 Human Anatomy and Physiology become adapted to secret and release milk instead of sweat. It functions as a permeability barrier, an emollient (skin softening) and a protective a gent against bacteria and fungi. Acne vulgaris is a condition when there is over secretion of sebum, which may enlarge the gland and plug the pore. It covers the entire body except the palms, soles, lips, tip of penis, inner lips of vulva and nipples. Hair consist epithelial cell arranged in three layers from the inside out medulla, cortex and cuticle. The bulb pushes in ward along its bottom to form a papilla of blood rich connective tissue. Part of the hair follicle is attached with the bundle of smooth muscle about halfway down the follicle. When it contracts in pulls the follicles and its hair to an erect position producing goose bump. The fastest growth rate occurs over 51 Human Anatomy and Physiology the scalp of women aged 16 to 24 years. Just before a hair is to be shed, the matrix cell gradually become inactive and eventually dies. Nails are composed of flat, cornified plates on the dorsal surface of the distal segment of the fingers and toe. The proximal part of nail is lunula, which is white in its color because of the capillaries underneath are covered by thick epithelium. The thicker layer of skin beneath the nail root is the matrix, where new cells are generated. Skin gets its color from a) Carotene b) Underlying blood vessels c) Melanin d) a and b only e) a, b and c 54 Human Anatomy and Physiology 4. Sudoriferous glands secret their secretion in response to: a) Physiological process b) Heat c) Stress d) Sexual experience e) In all of the above condition 5. Hair covers all of the following parts of the body except: a) Sole b) Face c) Neck d) Trunk. But from structural point of view, the human skeletal system consists of two main types of supportive connective tissue, bone and cartilage. Support: it forms the internal framework that supports and anchors all soft organs.

Learning objectives By the time the student is through with this lecture note he/she should be able to: 1. Introduction Human beings are subjected to a variety of metabolic diseases, as we are a complex set of structures that function through quite a varied and intertwined metabolic processes. Most metabolic diseases have genetic basis while some are acquired in life or need the complex interplay between nature and nurture for their existence. Genetic diseases either follow a single gene disorder or a polygenic basis with multifactorial disorders. Metabolic diseases with a single gene disorder these metabolic diseases follow a Mendelian type of inheritance i. Phenylketonuria, Galactosemia, Glycogen storage diseases); and x-linked recessive disorders (e. These are all rare Biochemical genetic diseases and they are beyond the scope of this lecture note. Metabolic disease with a polygenic disorder these metabolic diseases have multifactorial modes of inheritance. They are caused by the additive effects of two or more genes of small effect but conditioned by environmental, non-genetic influences. Example in these groups of metabolic diseases 213 includes Diabetes mellitus and Gout. Diabetes Mellitus the definition, classificatioin, epidemiology, pathogenesis, morphology, clinical featutres, diagnostic criteria, & complications of diabetes mellitus will be discussed next in this sequence. As to the new classification there are four types of diabetes of which the first two are the major types. This can be sited as evidence that genetic factors are involved in the pathogenesis of the disease. In studies of identical (monozygotic) twins in which one or both were diabetic, both members of the pair were affected in approximately half of the cases [i. B these 50 % concordance rate shows that environmental factors contribute to the development of the disease on a heritable predisposition 3. Additional evidence came from studies of genes that code for antigens of the major Histocompatibilty complex. The above three genetic factors/ evidences show that there is a genetic factor that is/ are important for the susceptibly to the disease and environmental factors are required to the development of an autoimmune reaction on these susceptible individuals. Circulating auto antibodies against components of the beta cells and against insulin were demonstrated in the large majority of all newly diagnosed children with diabetes.

Terefore cheap albendazole 400mg mastercard antiviral gene therapy research unit, appropriate treatment is required to improve the daily life of the patients buy albendazole on line amex antiviral in spanish. For clinical care of headache generic albendazole 400mg mastercard stories about hiv infection, use simple screeners and headache diary for diagnosis, severity evaluation, and treatment; evaluate the treatment efect appropriately; and it is also important to give proper guidance to the patients about the timing of taking acute medications for headache and on prophylactic treatment. To diagnose primary headaches, it is necessary to exclude the possibility of secondary headaches. In practice, precise history taking, neurological evaluation, sometimes blood tests and neuroimaging are necessary to exclude secondary headaches. If eye disease or disease of other discipline is suspected from the beginning, refer the patient to the respective specialist as soon as possible. When a diagnosis of primary headache is established, plan treatment according to this guideline. Simple screeners headache for use by primary care physicians have been developed, and reported to have high specifcity for the diagnosis of migraine. Use these screeners to aid diagnosis and evaluation of severity, and provide treatment appropriate to individual patients. As such, primary care physicians also have to be engaged in many aspects of headache management. Recommendation • Dentists should diferentiate between headache and temporomandibular disorder. Grade B Background and Objective Temporomandibular disorder occurs overwhelmingly more often in women, and is known to be a disease with gender diference. Primary headaches, especially migraine and tension-type headache, tend to occur concurrently with temporomandibular disorder. Moreover, since the pain experienced by patients with cluster headache and migraine sometimes involves the face and the teeth, these patients may visit dentists with the major complaint of toothache or temporomandibular pain. Dentists are recommended to have the capability of diferentiating these headaches from temporomandibular disorder and odontogenic pain. On the other hand, it has been reported that dental disease may be a cause of secondary headaches. Increased pericranial tenderness induced by palpation is the most signifcant abnormal fnding in patients with tension-type headache. The tenderness increases with the intensity and frequency of headache, and is further increased during actual headache. Pericranial tenderness is in fact tenderness of the frontal muscle, temporal muscle, masseter muscle, lateral and medial pterygoid muscle, sternocleidomastoid muscle, splenius muscle, and trapezius muscle. In another words, tension-type headache and myogenic temporomandibular disorder may be regarded as similar diseases with the same source of pain but diferent pain reception sites. Because the muscles are afected, stif shoulders and stif neck often occur concurently.
