  1. Secretory leukocyte protease inhibitor

    Secretory leukocyte protease inhibitor SLPI is a highly cationic single chain protein with eight intramolecular disulfide bond s. It is found in large quantities in bronchial, cervical, and nasal mucosa , saliva, and seminal fluids. SLPI inhibits human leukocyte elastase , human cathepsin G , human trypsin , neutrophil elastase, and mast cell chymase . X ray crystallography has shown that SLPI has two Homology biology homologous domains of 53 and 54 amino acids, one of which exhibits anti protease activity C terminal end C terminal domain . The other domain N terminal end N terminal domain is not known to have any function. Role in diseases The gene for SLPI is expressed by cells at many mucosal surfaces located in the tissues of the lungs, cervix, seminal vesicle s, and parotid duct s. SLPI is also one of the dominantly present proteins in nasal epithelial lining fluid and other nasal secretions. Many diseases, such as emphysema , cystic fibrosis , and idiopathic pulmonary fibrosis , are characterized by increased levels of neutrophil elastase. SLPI is one of the major defenses against the destruction of pulmonary tissues and epithelial tissues by neutrophil elastase. SLPI is considered to be the predominant elastase inhibitor in secretions, while Alpha 1 antitrypsin 1 antitrypsin is the predominant elastase inhibitor in tissues. Several diseases, including those listed, are actually the result of SLPI and 1 antitrypsin defenses being overwhelmed by neutrophil elastase. It has been suggested that recombinant human SLPI be administered to treat symptoms of cystic fibrosis, genetic emphysema, and asthma . In addition, SLPI has occasionally been monitored in an effort to coordinate its levels with different pathological conditions. Increased levels of SLPI in nasal secretions and bronchoalveolar fluids may be denotive of inflammatory lung conditions or allergic reactions ....

  1. Dog leukocyte antigen

    The dog leukocyte antigen DLA is a part of the major hisocompatability complex MHC in dogs, the DLA encodes for genes in the MHC. The DLA and MHC system are interchangeable terms in canines. The MHC plays a critical role in the immune response system and consists of three regions, class I, class II and class III. DLA is associated with the first two classes which are involved in the regulation of antigens in the immune system. The class II genes are highly polymorphic with many different alleles haplotypes that have been linked to diseases, alergies, and autoimmune conditions such as diabetes , polyarthritus, and hypothyroidism in canines. There s likely hundreds of immunologically relevant genes making up the DLA region in the canine genome , as of present date the complete characteristics of the gene is unknown. MHC genes represent candidate susceptibility in canines some alleles promote protection against immune mediated diseases and some increase susceptibility. For example certain combinations of the DLA DRB1 and DQ alleles are most favorable for good immune regulation. These alleles help balance immune surveillance and immune response without increasing the risk of developing an autoimmune condition. Different canine breeds have MHC DLA allele association these genes exhibit more inter breed differentiation than intra breed differentiation. Dogs have been selectively bred for different genotypes and phenotypes, selection in the DLA genome can lead to an increase in the prevalence of immune mediated diseases. Due to selective breeding some breeds have become restricted in their DLA genes which explain the different immune responses in different breeds.

  1. Lipohyalinosis

    Lipohyalinosis is a small Blood vessel vessel disease in the brain. Originally defined by Fischer as segmental arteriolar wall disorganisation , it is characterised by vessel wall thickening and a resultant reduction in Lumen anatomy luminal diameter. Fischer considered this small vessel disease to be the result of hypertension , induced in the acute stage by fibrinoid necrosis that would lead to Vascular occlusion occlusion and hence lacunar stroke. However, recent evidence suggests that endothelial dysfunction as a result of inflammation is a more likely cause for it. This may occur subsequent to blood brain barrier failure, and lead to Leukocyte extravasation extravasation of serum components into the brain that are potentially toxic. Lacunar infarction could thus occur in this way, and the narrowing the hallmark feature of lipohyalinosis may merely be a feature of the swelling occurring around it that squeezes on the structure. Hypertension is a strong causative factor. So called deep perforating arteries relatively small arteries branching off of relatively large arteries most commonly the lenticulostriate arteries from the middle cerebral artery are especially prone. ref Brenner D, Labreuche J, Pico F, et al. The renin angiotensin aldosterone system in cerebral small vessel disease . J Neurol . May 2, 2000 ref Uncontrolled hypertension and diabetes are risk factors for this condition. Lacunar infarct s are a result of atherosclerosis microthrombi and lipohyalinosis. These affect the deep structures of the brain and may leave small 5mm cavity lesions.

  1. Infiltration (medical)

    Infiltration is the diffusion or accumulation in a biological tissue tissue or cell biology cell s of substances not normal to it or in amounts in excess of the normal. The material collected in those tissues or cells is called infiltrate . Classification As part of a disease process, infiltration is sometimes used to define the invasion of cancer cells into the underlying matrix or the blood vessels.

During leukocyte extravasation white blood cell s move in response to cytokine chemicals chemotaxis , from within the blood out to infiltrate into the diseased or infected tissues. The presence of lymphocyte s in tissue in greater than normal numbers is likewise called infiltration. As part of medical intervention, local anaesthetics may be injected at more than one point so as to infiltrate an area prior to a surgical procedure.
