Preload is the load on the heart created by the volume of blood injected into the left ventricle by the left atrium (at the end of ventricular diastole) and that it must eject with each contraction. It... 

Afterload refers to the load on the contracting ventricle created by the resistance to the blood injected by the ventricle into the arterial system, i.e. the total peripheral resistance. Afterload is thus a pressure load and is excessive, e.g. in arterial h)rpertension.

Fig. 4. Virulence of strains by mouse infection. Following in vitro manipulation, strains were assessed for viralence by intraperitoneal injection of mice and subsequent microscopic detection of Giemsa-stained spirochetes in blood. Injection of equal numbers of (A) electrocompetent Borrelia hermsii DAH 2E7, (B) electroporated without a manipulation constmct or antibiotics and cloned by limiting dilution, and (C) the vtp mutant all produced comparable spirochetemias at 65 h post infection. Images of infected blood were taken at 400x.

The ERG of the left eyes at 7 days showed greatly decreased a-wave and b-wave after injection. Blood-injected eyes had marked reduced a-wave and b-wave at 28 days after injection. It is found that reduction in a-wave exceeded the decrease in b-wave (Figure 4).

C. It is secreted along with noradrenaline by the adrenal medulla, from which it may be obtained. It may be synthesized from catechol. It is used as the acid tartrate in the treatment of allergic reactions and circulatory collapse. It is included in some local anaesthetic injections in order to constrict blood vessels locally and slow the disappearance of anaesthetic from the site of injection. Ultimately it induces cellular activation of phosphorylase which promotes catabolism of glycogen to glucose. 

A base, formed by the bacterial degradation of histidine, and present in ergot and in many animal tissues, where it is liberated in response to injury and to antigen-antibody reactions. If injected it causes a condition of shock with dilatation of many blood vessels, loss of plasma from the capillaries to the tissues and a rapid fall in blood pressure. It is normally prepared from protein degradation products. 

Species origin tests, used to determine whether the specimen is human or from another source, are immunological in nature. Host animals, usually rabbits, are injected with protein from another species. The animal creates antibodies to the unknown material. Semm from the host animal, containing species (human, bovine, equine, canine, etc) specific antibodies, is tested against a dilute solution of blood (antigens) collected as evidence. A positive reaction is determined by a visible band where the antibodies and antigens come into contact. 

The posterior lobe of the pituitary, ie, the neurohypophysis, is under direct nervous control (1), unlike most other endocrine organs. The hormones stored in this gland are formed in hypothalamic nerve cells but pass through nerve stalks into the posterior pituitary. As early as 1895 it was found that pituitrin [50-57-7] an extract of the posterior lobe, raises blood pressure when injected (2), and that Pitocin [50-56-6] (Parke-Davis) causes contractions of smooth muscle, especially in the utems (3). Isolation of the active materials involved in these extracts is the result of work from several laboratories. Several highly active posterior pituitary extracts have been discovered (4), and it has been deterrnined that their biological activities result from peptide hormones, ie, low molecular weight substances not covalendy linked to proteins (qv) (5). 

Adverse side effects of gold treatments include stomatitis, rash, and proteinuria. Complete blood counts and urinalysis should be performed before each or every other injection of gold compounds. Pmritic skin rash and stomatitis are more common adverse effects that may resolve, if therapy is withheld for a few weeks and then restarted cautiously at a lower dose. Oral gold causes less mucocutaneous, bone marrow, and renal toxicity than injectable gold, but more diarrhea and other gastrointestinal reactions appear. 

One method of treatment is to inject calcitonin, which decreases blood Ca " concentration and increases bone calcification (33). Another is to increase the release of calcitonin into the blood by increasing the blood level of Ca " ( 4). This latter treatment is accompHshed by increasing Ca " absorption from the intestine requiring dietary calcium supplements and avoidance of high phosphate diets. The latter decrease Ca " absorption by precipitation of the insoluble calcium phosphate. 

Direct. Some radionucHdes are packaged in solution for direct sampling (qv) via a septum and injection into the patient. GalHum-67 is a marker of inflammation, infection, and various tumor types. Its half-life is 78.3 h and it is suppHed as the gallium citrate salt. Indium-111 chloride is suppHed for the labeling of white blood ceUs. The In chloride is mixed with oxine (9-hydroxyquinoline) to form a lipophilic, cationic In oxine complex, which enters the white blood ceU. The complex dissociates within the ceU, and the cationic In " ion is trapped within the ceU, owing to its charge. 

Strontium-89 chloride is a calcium analogue that rapidly clears from the blood and is taken up into bone mineral, particularly in areas of active osteogenesis, as weU as primary bone tumors and metastases. It is used for reHef of bone pain in patients having painful skeleton bone metastases. It is suppHed in an injectable solution.
