Lectures

The lecture „Passive electrical properties of tissues“ is aimed to explain basic terms, quantities and units necessary to understand electrical properties of biological tissues. It contains physiological values of individual quantities for some tissues and organs, electrical model of these properties, describes effect of electric current on tissues and its use in diagnostics and therapy. The lecture also includes safe values of electric current and rules for event of injury by electric current.

Lymphatic vessels (lymphatic capillaries, collecting vessels, collecting ducts), lymph (origin, composition, formation), lymph flow (intrinsic and extrinsic mechanism), lymphatic tissues and organs (lymph nodes, mucosa associated lymphoid tissue - MALT, spleen, thymus), functions of lymphatic system.

Functional morphology of the vessels, general hemodynamics (velocity of blood flow, flow rate, types of blood flow, blood pressure, resistance of the vessels), functions of arteries, functions of capillaries, functions of veins, regulation of the vascular system, specifics of some circulations (coronary, cerebral, pulmonary, renal, hepatic, skeletal muscle and cutaneous).

Blood - composition and function. Blood and homeostasis. Red blood elements, haemoglobin. Blood groups, cross-matching test. Erthrocyte sedimenation rate, haematocrit. Leukocytes - types and their immune functions. Platelets and haemostasis. Haemocoagulation. Blood plasma - composition, functios. Haemopoiesis.

1. Part 1 - Physiology of the heart
Contents: Functional morphology of the heart, physiological properties of the heart (chronotropy, dromotropy, bathmotropy, inotropy), metabolism of the heart, cardiac cycle, manifestations of the heart activity (acoustic, electric, mechanical), regulation of the heart (autoregulation, nervous regulation, humoral regulation, effect of the temperature on the heart)

 

Slides to the lecture on blood physiology.

Blood - composition, functions. Erythrocytes and their function, haemoglobin. Blood groups. Platelets and haemostasis. Leukocytes and their immune unctions. Plasma - composition, function, osmotic and oncotic pressure. Haemopoiesis. Blood and acid-base balance.

Priapism is an abnormal penile erection which is generally not initiated by sexual stimulation and doesn’t lead to ejaculation lasting more than 6 hours in a case of ischemic priapism. It is an urgent medical condition that requires evaluation and often rapid treatment to avoid loss of erectile function. The priapism may result either from  reduction or loss of the normal venous outflow from the penis=veno-occlusive, ischemic, anoxic or low-flow priapism  or abnormal arterial inflow into the penis= arterial, non-ischemic or high-flow priapism.

Femtosecond laser uses an infrared beam of light to precisely separate tissue through a process called photodisruption by generating pulses as short as one-quadrillionth of a second. It has wavelength of 1053 nm and is based on the technology whereby focused laser pulses divide material at the molecular level without transfer of heat or impact to the surrounding tissue.

Creation of 3D atlas of human bones as an internet page with use of HTML5, Javascript, PHP and MySQL. To obtain polygonal models surface scanners and CT i-CAT scanner were used. Scanned models are true human bones, property of Department of Anatomy LF UK. Primary audience of the atlas are students of medicine. Atlas contains also interactive annotations, automatic search and visualisation of bone structures on 3D models, brief charts with key facts about bones and quizzes.

Here you can find some basic things, which should be done with average patient before surgery.

It has 5 basic steps - lowering the risk of the surgery, appropriate diagnosis, preparation of the operation field, psychological preparation and informed consent.

There are some links to other pages as well.
