BIOLOGY LAB REPORT 2.docx
This laboratory report describes two experiments observing cells under a microscope. In the first experiment, the group observed cheek cells and onion epidermal cells. They stained the cheek cells with methylene blue and observed them under a microscope. They found that cheek cells do not have a cell wall or prominent vacuole. For onion epidermal cells, they observed cell walls and large vacuoles, indicating they were plant cells. In the second experiment, the group's objective was to prepare a temporary stained and mounted slide. They describe techniques for staining, fixation, permeabilization and mounting to enhance contrast and visibility of cells under a microscope. Staining helps reveal details of cellular structures like organelles, nuclei and cell walls.

crushsyndromeppt-1-200601160315 (1).pptx
Crush syndrome is caused by prolonged pressure on muscle tissue, leading to rhabdomyolysis. This releases myoglobin and other intracellular contents into the bloodstream, which can cause kidney damage, metabolic abnormalities, and complications affecting other organs. Treatment involves aggressive fluid resuscitation, dialysis if needed to manage kidney dysfunction, and surgery such as fasciotomy to release pressure in compartments. Early medical management is important to prevent further complications from crush syndrome.

1) Arterial blood pressure is regulated by the balance of cardiac output and peripheral resistance, with regulatory systems including baroreceptors and the renin-angiotensin system maintaining homeostasis.
2) Primary hypertension has an unknown cause but may involve defects in regulatory mechanisms or membrane ion pumps, while secondary hypertension can result from renal, endocrine, neurogenic, drug or other causes that increase blood volume or activate vasoconstriction.
3) Uncontrolled hypertension can lead to organ damage over time through mechanisms such as left ventricular hypertrophy, atherosclerosis, stroke and renal failure.

Design & functioning of an ultrasound therapy device.pptx
Ultrasound therapy uses high frequency sound waves to deliver thermal and non-thermal effects to tissues. It can be used to treat a variety of musculoskeletal conditions. The device generates frequencies between 1-3 MHz which determine treatment depth. Coupling methods like gel or immersion in water are required to transmit ultrasound to the body. Treatment parameters like duration, intensity and duty cycle are set based on the target tissue and therapeutic goals. Precautions must be taken when using ultrasound near the spine or growing bones. Proper maintenance ensures safe and effective use of these devices.
Biophysical action of Direct current on living tissues.pptx
Direct current (DC) therapy, also known as galvanization therapy, uses low voltage DC to treat tissues and reduce pain. DC is more likely than alternating current (AC) to cause muscle tetanus and "freeze" victims during electrical accidents. Galvanization therapy increases blood flow and promotes healing by improving tissue metabolism. It is applied using dry or moist electrodes in transverse, longitudinal, or dotted patterns. While it can treat conditions like pain and inflammation, galvanization therapy should not be used for acute issues, cancers, or in patients with poor heart health.

allergyhypersensitivity-140807031901-phpapp01.pptx
This document discusses allergy and hypersensitivity. It defines allergy as a disorder of the immune system where allergic reactions occur to normally harmless environmental substances known as allergens. Hypersensitivity reactions are excessive, undesirable reactions produced by the normal immune system that require a pre-sensitized immune state. There are four types of hypersensitivity reactions classified by Gell and Coombs based on the mechanisms involved and time taken for the reaction: type I is immediate hypersensitivity mediated by IgE and mast cells; type II involves IgG or IgM; type III involves IgG, complement and immune complexes; and type IV is delayed hypersensitivity mediated by cell-mediated immune memory responses.
LEVELS OF EVIDENCES.pptx
The document outlines 7 levels of evidence for medical research, with level 1 being the highest and consisting of systematic reviews and meta-analyses of randomized controlled trials (RCTs) or evidence-based guidelines based on RCTs, and level 7 being the lowest level based on expert opinions. Different clinical questions are best answered by different types of studies, and the highest levels of evidence may not always be available, so researchers should work their way down to the next highest available level of evidence.
INFLAMMATION — копия.pptx
Inflammation is characterized by cardinal signs such as redness, swelling, heat, and pain. It involves a complex series of events including increased blood flow, vascular permeability, and migration of leukocytes. Mediators like histamine, cytokines, prostaglandins, and leukotrienes are released from cells to induce and propagate the inflammatory response through effects on blood vessels and immune cells. Acute inflammation resolves within days while chronic inflammation persists long-term and can cause tissue damage.
addictiveandpsychotropicdrugs-130906114151-.pptx
This document discusses psychoactive drugs, also known as psychotropic or psychopharmaceutical drugs. It provides definitions and describes how these drugs affect the central nervous system and alter perceptions, moods, and behaviors. The document also summarizes key points about the history of psychoactive drug use, common classes of psychotropic drugs, their medical and non-medical uses, methods of administration, effects on neurochemistry, risks of addiction, and regulations around legality.
narcoticandnon-narcoticanalgesics-151112065434-lva1-app6892 (1).pptx
- Nociception is the transmission of noxious stimuli to the CNS, while pain is a subjective experience. Pain receptors transmit signals that result in pain perception.
- There are different types of pain including acute vs chronic, nociceptive vs neuropathic, somatic vs visceral, and referred pain.
- NSAIDs work by blocking cyclooxygenase (COX) enzymes and subsequent prostaglandin synthesis. COX-1 inhibition results in side effects while COX-2 inhibition provides pain relief.
- Opioid analgesics work in the CNS by binding to opioid receptors like mu and kappa receptors to reduce pain signal transmission.
adrenergicneurotransmission-190131061307.pptx
This document provides information on adrenergic transmission, receptors, and drugs. It discusses the endogenous catecholamines epinephrine, norepinephrine, and dopamine, including their synthesis, storage, release, metabolism, and effects. It describes the different types of adrenergic receptors and their subtypes. The document also examines various adrenergic drugs, including direct-acting drugs like epinephrine, norepinephrine, phenylephrine, and indirect-acting drugs like amphetamines. It discusses the therapeutic uses, pharmacokinetics, mechanisms of action, and side effects of many commonly used adrenergic drugs.
cholinergicdrugs-151225163545.pptx
This document provides an overview of the nervous system and autonomic nervous system, with a focus on the cholinergic system. It describes the organization and functions of the sympathetic and parasympathetic nervous systems. It discusses cholinergic transmission in detail, including the different types of cholinoceptors (muscarinic and nicotinic), the mechanism of cholinergic transmission, and cholinergic drugs. It summarizes the pharmacological actions and uses of cholinergic agonists like acetylcholine and cholinesterase inhibitors.
