In the long history of medical development, penicillin is like a star, shining the light of life. Its emergence was a major milestone in the human journey against bacterial infections and profoundly changed the face of health care.
Penicillin is an antibiotic with a unique source and is derived from penicillin. Cyclops are not rare in nature, yet their antibacterial properties have been discovered as a result of keen observation and tireless research by scientists. Before penicillin is discovered, bacterial infections are often fatal threats. Small wounds, pneumonia, meningitis and other diseases could have taken the lives of patients in cold blood, and doctors were often helpless in the face of those conditions.
The mechanism of penicillin is excellent. Bacteria have cell walls to maintain their structure and protect themselves, while penicillin can interfere with the synthesis of bacterial cells. During the breeding period of bacteria, penicillin acts as a critical part of the cell wall synthesis process, resulting in the loss of the cell wall. As a result of high intrabacterial permeability pressure, water flows into the bacteria in the event of damage to the cytowall, leading to bloated and broken bacteria dying. This unique form of attack against bacterial cell walls has enabled penicillin to show a remarkable microbicide for most gland positive bacteria. For example, penicillin can be effectively eliminated for streptococcus, which causes common diseases such as tonsilitis, pneumonia and skin infections.
Penicillin is widely used in the medical field. In the treatment of pneumonia, it is able to rapidly curb the reproduction of pathogenic bacteria, such as pneumocococcal, to reduce lung inflammation and to alleviate the symptoms of respiratory difficulties and high fever of patients, and to significantly reduce mortality from pneumonia. In the case of meningococin, which is a dangerous brain-infected disease, penicillin can go through the blood-brain barrier to reach the infected areas and strike at pathogens such as meningitis bioccal, offering hope for recovery. Penicillin also plays an important role in the treatment of sexually transmitted diseases, such as gonorrhoea, by effectively controlling the development of conditions and reducing the incidence of complications. However, the use of penicillin is not without risk, the most worrying of which is the allergies. The mechanisms for the occurrence of allergies are complex and involve the unusual identification of penicillin by the human immune system. Patients may have symptoms such as rashes, itchings, life-threatening conditions such as respiratory difficulties, reduced blood pressure and allergic shock. That’s why, before using penicillin, doctors must ask patients to have a skin test. The pictorial test allows some prediction of whether the patient is allergic to penicillin, thus avoiding a serious allergic reaction.
The discovery of penicillin is incidental and inevitable. Scientist Flemming found no bacterial growth around the fungus in an occasional experimental observation, thus initiating a study tour of penicillin. But what happens is that scientists have a long history of exploring and focusing on microorganisms and antibacterials. In follow-up studies, numerous scientists have been involved in the continuous improvement of penicillin extraction and production methods to enable them to be produced in large quantities and applied to clinical purposes.
Today, penicillin remains one of the essential drugs in the medical arsenal. Although antibiotics are increasingly being developed over time, the status of penicillin is unshakeable. Not only does it continue to play a role in the treatment of diseases, but more importantly, it has laid the foundation for the subsequent development of antibiotics and inspired in-depth research by scientists on micro-organisms. It is the birth of human wisdom and the spirit of scientific exploration and witness the great progress of humankind in the fight against disease.
