The tissue damage excites an inflammatory response cheap levothroid 50mcg on line thyroid nodules pain, the exudate adding more fibrin to the clot already present 50mcg levothroid thyroid symptoms protruding eyes. The inflammatory changes differ in no way from those seen in other inflamed tissues. Macrophages invade the clot and remove the fibrin, red cells, the inflammatory exudate, and debris. Any fragments of bone, which have become detached from their blood supply, undergo necrosis, and are attacked by macrophages and osteoclasts. Following this phase of demolition, there is an ingrowth of capillary loops and mesenchymal cells derived from the periosteum and the endosteum of the cancellous bone. These cells have osteogenic potential and together with the newly formed blood vessels contribute to the granulation tissue formation. The mesenchymal osteoblasts next differentiate to form either woven bone or cartilage. The term callus, derived from the Latin and meaning hard, is often used to describe the material uniting the fracture ends regardless of its consistency. When this is granulation tissue, the callus is soft, but as bone or cartilage formation occurs, it becomes hard. The dead calcified cartilage or woven bone is next invaded by capillaries headed by osteoclasts. As the initial scaffolding (provisional callus) is removed, osteoblasts lay down osteoid, which calcifies to form bone. Its collagen bundles are now arranged in orderly lamellar fashion, for the most part concentrically around the blood vessels, and in this way the Haversian systems are formed. Adjacent to the periosteum and endosteum the lamellae are parallel to the surface as in the normal bone. The final remodeling process involving the continued osteoclastic removal and osteoblastic laying down of bone results in the formation of a bone, which differs remarkably little from the original tissue. The external callus is slowly removed, the intermediate callus becomes converted into compact bone containing Haversian systems, while the internal callus is hollowed out into a marrow cavity in which only a few spicules of cancellous bone remain.

Explain how fluid balance is maintained across the arteriolar & venular end of the vasculature by Starling forces 2. Know the pathologic conditions occurring when the balance between the above forces is disrupted across the vascular wall under different conditions, i. Understand and explain the cause and pathogenesis of clinical conditions like myocardial infarction, deep venous thrombosis, pulumonary thromboembolism, etc. Know the pathogenesis of edema of congestive heart failure, nephrotic syndrome, cirrosis, and other clinical conditions 5. Have the basic knowledge about various types of shock, their pathogenesis, manifestations, and complications. Introduction The health and well-being of cells & tissues depend not only on an intact circulation to deliver nutrients but also on normal fluid hemostasis. Edema Definition: Edema is increased fluid in the interstitial tissue spaces or it is a fluid accumulation in the body cavities in excessive amount. Depending on the site, fluid accumulation in body cavities can be variously designated as: a) Hydrothorax fluid accumulation in pleural cavity in a pathologic amount. Mechanism of edema formation: Approximately 60% of the lean body weight is water, two-thirds of which is intracellular with the remainder in the extracellular compartment. The capillary endothelium acts as a semipermeable membrane and highly permeable to water & to almost all solutes in plasma with an exception of proteins. Proteins in plasma and interstial fluid are especially important in controlling plasma & interstitial fluid volume. Normally, any outflow of fluid into the interstitium from the arteriolar end of the microcirculation is nearly balanced by inflow at the venular end. Edema formation is determined by the following factors: 1) Hydrostatic pressure 2) Oncotic pressure 3) Vascular permeability 4) Lymphatic channels 5) Sodium and water retention We will discuss each of the above sequentially. There are four primary forces that determine fluid movement across the capillary membrane. Each of them can be listed under the above two basic categories, the hydrostatic pressure & the oncotic pressure. The capillary hydrostatic pressure (Pc) This pressure tends to force fluid outward from the intravascular space through the capillary membrane to the interstitium. The interstial fluid hydrostatic pressure (Pif) This pressure tends to force fluid from the interstitial space to the intravascular space. The plasma colloid osmotic (oncotic) pressure (p) This pressure tends to cause osmosis of fluid inward through the capillary membrane from the interstitium. The interstial fluid colloid osmotic (oncotic) pressure (if) This pressure tends to cause osmosis of fluid outward through the capillary membrane to the interstitium. The plasma oncotic pressure is decreased when the plasma proteins are decreased in various diseases such as: 1. Edema resulting from increased capillary hydrostatic pressure as in the following diseases: 1.
At cerebrum and globus buy levothroid 100mcg with mastercard thyroid urination, the lanthanides came associated with both ferrous and ferric iron deposits 50mcg levothroid sale thyroid cancer celebrities, as is usual. All were present in Georges cerebrum, but none were present in the cerebrum white blood cells! The cerebral and globus white blood cells were empty, were not eating the intruders. Wherever there were calcium and iron deposits the normal digestive enzyme pancreatin was missing. All normal tissues were supplied with pancreatin which lasted for many hours after a meal. Normal tissues also had phosphatydyl serine, a molecule in the cell membrane that could declare the cell was ready for digestion. A search of the lanthanide research lit- erature showed that they have long been known to cause calcium precipita- tion inside cells. But why were they present in the lysosomes along with iron Jan 15 no change deposits? There was a strange possibility; the lanthanides and iron could be attracting each other due to their magnetic properties. We gave George such a patch, facing the North (by biological convention) side against his skin. He was taken off many other supplements since they were obviously not able to remove iron, lanthanides, and calcium deposits. A week later, there was still some thulium; even two weeks later there was thulium. Two weeks after starting to wear the tiny magnet patch, Georges iron deposits had left the cerebrum as well as the lanthanides. The cell-flag for digestion, phosphatidylserine, was now Positive, and with it pancreatin. In fact, nucleosides were still present, the digestion- flag was not up, and pancreatin was not there either. Coxsackie viruses were coursing about, but were found in the white blood cells, too, protecting him. Days later at the globus, hydroxyurea (from some distant Ascaris eggs) was still Positive. Only gallstones could easily explain this; he must have the eggs in his gallstones, forever seeding his brain and cyst with them. He was instructed to do a liver cleansehis fifth one, and the day after the cleanse to take 3 freeze-dried black walnut capsules four times a day to stamp them out. But two days after his cleanse he still had Ascaris eggs in liver, gall- bladder, and bile ducts. It showed a huge reduction in tumor-cyst sizeto less than half its previous dimensions. A spot could still be found in his globus pallidus that harbored acrolein, a fat derivative similar to burnt grease and very carcino- genic by scientific stan- Feb 19 reduced by half dards. Of all the pancre- atic enzymes seen there by Syncrometer, only lipase was still missing, and also missing in our supplement of pancreatin. George had to be jolted into realitythat it was really happening for himbut still with cau- tious interpretation. Al- though the tumor-cyst was down to 9 x 10 mm, it could still easily fill up again if he were to get a dose of Ascaris or common food bacteria. It was only on this day, seven months after his arrival, that he allowed himself to repeat the exact words of his doc- tor at home: You will die. When he arrived August 3, his alk phos was clearly elevated, but was it due to his status as a young growing boy? But there is a cyst remnant remaining, a calcified pineal to rescue and, ultimately, a shunt to remove. There was no hint of devel- oping mental impairment, although she was eighty-five now. She walked with ease; in fact, she had fallen re- cently at home without the slightest injurycontrasting with the frequent breaks she used to endure in the past. She had agreed to a follow-up bone scan even Katherine Morales three years later though bone density does not improve enough to show decisively on an X-ray, after bone cancer clears up. I thought that surely a little improvement in bone density would be visible, though. I searched for all the amino acids in her brain, since she seemed so young in attitude. She had no pockets of streptococcus bacteria throughout her body to make phenol: only in her joints were they Positive. L-ascorbic acid Positive L-threose Negative dehydroascorbic acid (oxidized) Negative D-threose Negative glutathione Positive L-xylose Negative glutathione (oxidized) Negative D-xylose Negative ferrous gluconate Positive L-lyxose Negative ferric phosphate (oxidized) Negative L-cysteine Positive iron sulfide FeS Positive L-cystine (oxidized) Negative iron sulfide FeS2 (oxidized) Negative She was not over-oxidized! Surely she was benefiting from this diet the way our patients benefit from the chicken broth that is part of their 21 Day Program. Especially along the back of the head and neck and upper spine; the bone appears entirely normal. Summary: Katherine worked hard to recover from the bone cancer that gave her painful lesions, too numerous to count three years ago. She had denturesshe was not burdened with the extra toxicity of metal, plastic, or infections of the jaw that come with numerous restorations. Besides this, the extra high doses of rhodizonate she took initially surely would have detoxified the food dyes accumulated in her body. We knew nothing about them at that time; we now accomplish this with co- enzyme Q10 and vitamin B2. After overcoming her bone cancer, she not only became well, but extraordinarily well.
