ALEXANDER FLEMING

                     Alexander Fleming, who was born on the 6^th of August 1881 in Litchfield, was a Scottish bacteriologist. This scientist invented penicillin in 1928. Penicillin is a substance which can be used for preventing the growth of bacteria.

                                         The story of the discovery of penicillin is very interesting.

                            One day while Fleming was using a dish for his antibacterial experiments, be noticed that some strange flecks of fungus had grown in that uncovered dish containing mucus from infected wounds. He also noticed that this fungus had killed the bacteria, on that dish. The fungus had been caused by a spore which had flown in through a window and settled on the dish. In his further experiments be found that it was penicillium which was a rare fungus in the mould family

SIR ISAAC NEWTON

                Sir Isaac Newton was born on the 25^th of December, 1642 in Lincolnshire. While in school he did not do well, but possessed greater talents in drawing and mechanical inventions. Fortunately one of his uncles saw his talents and made the way for him to enter Trinity College. There he graduated in mathematics in 1669. He worked closely with his professor Isaac Barrow who gave him every help to improve his talents. Later Isaac Newton succeeded his professor and became professor of mathematics at Trinity at the age of twenty seven.

THE CEYLON ELEPHANT

The elephant is the king of the Ceylon jungle. No other animal dares to challenge his kingship. In their wild state, elephant live in small herds, about twenty-five in each. A full-grown male is usually the leader of the herd. Such a leader, in all his majesty and dignity, roams the jungle with his followers. Some elephants have tusks from which we obtain ivory; but “tuskers” are now rare in Ceylon.

Human Blood Circulation

Imagine being smaller than the period at the end of the sentence. Imagine being microscopic! Suppose you are almost as tiny as a red blood cell. Picture your self inside a human heart. You are about to take a guided tour of a human circulatory system.

                Your tour being in the right at rium of the heart. It is a dark chamber with thin walls. Wow……..Is it crowded! Millions of blood cells are in the right atrium with you. Most of the cells are about your size. The guide says that, they are red blood cells “Each one is shaped like a doughnut with no hole. Most have no nucleus. Every red blood cell carries a load of carbon dioxide”

                The large cell with nuclei are white blood cell “the guide continues” what are the disk shapes?” you ask “They are platelets,” the guide answers, “and the yellowish, watery substance around you is plasma.”

Renal diseases are on the rise

What is kidney failure?

               Kidney is the organ that purifies the blood and is responsible for filtering blood, removing waste and making urine to keep the body’s water and salt balance in check. When the kidney stops functioning this process can not go on.

 

What is the role of the dialysis machine?   

                              When the patient’s kidney ceases to function, the machine will play the role of kidneys. The machine will take the blood in and send it through an artificial kidney which the blood, and send it to the patient.

Cell (The fundamental unit of life)

Latin world for cell is "cellula" which means 'a little room'.The word 'cell' has derived from the above Latin word 'cellula'.The British botanist Robert hooke while examining a bottle cork under the microscope made by himself, observed room like structutes as in a honey comb. He named the little rooms of the honey comb as cells. Actually he has  seen only the cell wall.
                              All the living organisms are made up of cells. There are some organisms of which the body is made up of only one cell. They are called unicellular organisms. Organisms with more than one cell are multi cellular organisms.

                            It was MATTAIAS SCHLEIDEN in 1838 who first proposed the idea that all plants consist of calls.
