[What is St. John's wort]

St. John’s wort (Hypericum perforatum) has a history of use as a medicine dating back to ancient Greece, where it was used for a range of illnesses, including various nervous disorders. St. John’s wort also has antibacterial, antioxidant, and antiviral properties. Because of its anti-inflammatory properties, it has been applied to the skin to help heal wounds and burns. St. John’s wort is one of the most commonly purchased herbal products in the United States.

In recent years, St. John’s wort has been studied extensively as a treatment for depression. Most studies show that St. John’s wort may help treat mild-to-moderate depression, and has fewer side effects than most other prescription antidepressants.

Biology (Grade 9): High School Learning: CELL WALL:
Cell Wall- A Protective layer surrounding the cell on the outside of the plasma membrane.
Cell Wall is only present in plant cell.
Cell Wall consists of 3 layers.
- Middle lamellla.- Outer wall.
- Primary Wall- Formed after middle lamella and consists of a skeleton of cellulose microfibrils, embedded in gel like matrix of pectic compounds, hemicellulose, and glucoprotein.

- Secondary Wall:
Formed after cell enlargement is completed , provides compression strength.

- Plasmodesmata: Connection between cells,A microscopic channels through the cell walls and lamella.

Cell Wall and Turgor:
- Cell Wall is made of neutral and charged polysacchrides absorbs H2O because it has a hypotonic environment.

- Increased H2O in the cell – Turgor Pressure. If a plant cell is turgid . it is very form , a healthy state in the most plant,If plant is flacid . it is isotonic solution.

Difference between CELL MEMBRANE and CELL WALL.

Poly-N-acetyl glucosamine (PNAG) is a broadly expressed surface or capsular polysaccharide detected on major bacterial and eukaryotic pathogens. Natural antibody to PNAG is generally poorly effective at mediating protection against infection, but by using modified glycoforms of the antigen antibodies can be elicited or selected from libraries that have the ability to kill target organisms facilitated by activation of the classical pathway of complement. Protective efficacy has been validated in a broad range of mouse systems of infection with different organisms and in pigs challenged with Actinobacillus pleuropneumoniae. The unexpected discovery by multiple investigators of a highly conserved surface antigen on most major pathogens, and means to engender effective immunity, opens up the potential for a single vaccine to provide partial or perhaps complete protection against many of the major infectious agents relevant to animal and human health.
