Drug Trials

A pharmaceutical drug are used to diagnose, cure, treat, or prevent disease.

There are two main sources of drugs, plants and microorganisms.

There are a lot of drugs that use plant resources. For example:

  1. Digitalis’ leaves are used in the drug Digoxin to treat congestive heart failure (CHF).
  2. Cinchona’s bark is used in the drug Quinine to treat Malaria.
  3. Opium’s fruits are used in the drug Morphine to treat Analgesic.
  4. Eserin’s seeds are used in the drug Anticholinestrase to treat Myasthenia gravis (MG)

There are a lot of drugs that use microorganisms resources. For example:

  1. The drug Penicillin is made from penicilium notatum.
  2. The drug Chloramphenicol is made from Streptomyces Venezuelace.
  3. The drug Griseofluvin in made from Penicillin grisofullivum.
  4. The drug Streptomyum is made from Streptomyces griseus.
  5. The drug Neomycin is made from Streptomyces fradiae.

Drugs are not just developed and then used. All drugs have to be tested to make sure that they work, and are safe, before they can be prescribed. Furthermore, all drugs have to pass 3 tests:

  1. The drugs are tested using human cells grown in the laboratory.
  2. Drugs are then tested on animals. That is done by giving a drug to the animals, then monitoring them carefully for any side-effects.
  3. Clinical trials. They are tested on healthy volunteers to check they are safe. Very low doses of the drug are given to begin with. If there are no problems, further clinical trials are done to find the optimum dose for the drug.

The first test is always done on human cells grown in the laboratory to test their if the drug kills any cells or causes the cell to stop functioning properly and if the drug does what it is supposed to do. This is not done on animals (mostly mice because of the similarity of DNA between humans and mice) because of the strict laws of tests in animals in the UK. If the drug passes the test, it is then considered safe for animals use. The drug is now guaranteed to be doing what it is supposed to be doing and it needs to be tested for side effects. If there are no risky side effects the drug is tested on healthy human beings to see the effects of the drug in the human body and if it is safe or not for human use. If it passes all of those tests, clinical trial are carried to find the optimum dose of the drug. After that the drug is submitted to the NDA. When the NDA approves the drug, the drug starts getting marketed.

The three phases of clinical trials are:

  1. Phase I trials, usually in healthy volunteers, determine safety and dosing.
  2. Phase II trials are used to get an initial reading of efficacy and further explore safety in small numbers of patients having the disease targeted by the NCE.
  3. Phase III trials are large, pivotal trials to determine safety and efficacy in sufficiently large numbers of patients with the targeted disease. If safety and efficacy are adequately proved, clinical testing may stop at this step and the NCE advances to the new drug application (NDA) stage.

What An Antibody Is And What Their Role Is In Preventing Reinfection In Diseases Such As Chicken Pox?

Micro organisms are divided into three classes:

-Bacteria

-Viruses

-Fungi

Chicken pox is a viral infection caused by vaicella zoster virus or (VZV). The most important point to get is that not all micro organisms are infectious. The infectious micro organisms are known as Pathogens. Humans have developed a defence mechanism to defend them from Pathogens called the Immune System. The Immune System consists of white blood cells, and they have another name: Leukocytes. White blood cells include macrophages which are a type of phagocytes. Phagocytes are large cells that attack and feed on foreign microscopic things out of a cell, and then digest them, this also known as engulfing and digesting. However, that is not the only type of a white blood cell, there is an other type which is the lymphocyte. Lymphocytes also have two sub-types which are the B cells and the T cells. B cells get their name from their development of bone morrow. B cells create antibodies. T cells get their name from their development of a small organism known as thymus gland. T cells are responsible for attacking cells infected by the help of macrophages and they activate phagocytes. B cells cause antibodies that are proteins to counteract an antigen. Antigens are structures that are in all pathogens. Antibodies try to bind with antigens disabling them by activating a cascade of nine proteins , known as complement. Complement help assist the antibodies in destroying the bacteria.The Pathogens are the labelled based on their antigens, the B cells then produce memory cells that help create antigens for that pathogen i.e. chicken pox which helps the antibodies to react quickly in case of reinfection. Once the immune system reaches this level, it has gained a status known as “Acquired Immunity” against that pathogen.

How does Shakespeare present Macbeth’s deteriorating state of mind?

Shakespeare presents Macbeth’s deteriorating state of mind using a variety of language devices and techniques.

MACBETH

Oh, full of scorpions is my mind, dear wife!

Macbeth’s manhood gets questioned a lot by Lady Macbeth. Lady Macbeth plays a big role as an evil influence to Macbeth. From the instant that he told his wife about his ‘black and deep desires’ of being a king. Shakespeare tries to use Lady Macbeth as a device to start the deterioration siding with the short evil way, persuading him to abandon his morals as a brave courage man. This is Dire Ambition.
Macbeth’s mental status is like a train that stops in different stations for a small amount of time and then moves to another station until the end of the journey. Observing the play from the beginning of the play to the end of it. We explore major shifts on Macbeth’s life that, not just change his way of thinking about life. The witches changed his attitude towards the people surrounding him. This does not mean that the killing he has done and the isolation he did put him self in eventually is because of the witches. That is the idea that Shakespeare is trying to enforce. If you are willing to do bad things, be ready and have the courage to face the consequences.
Shakespeare uses a variety of language techniques such as metaphor to present Macbeth’s deteriorating state of mind. Just when he killed King Duncan, Macbeth hears a voice telling him that he will not sleep again. Shakespeare uses a lot of metaphors to describe the feeling that he has towards sleeping since Macbeth thinks he is not going to sleep again. When he says,

MACBETH
—the innocent sleep,
Sleep that knits up the raveled sleave of care,
The death of each day’s life, sore labor’s bath,
Balm of hurt minds, great nature’s second course,
Chief nourisher in life’s feast.

He is saying that sleeping removes all the worries that a human being has. Sleeping is a comfort for tired people and it heals damaged minds. Shakespeare uses all of those metaphors to strengthen the idea of despair.

When Macbeth killed Banquo, Macbeth started seeing a ghost that resembles Banquo with 20 stabs on the head. Macbeth gets frustrated and says,

MACBETH
Thou canst not say I did it: never shake Thy gory locks at me

This is called the use of metaphysics. Because you cannot provide evidence of the existence of the ghost of Banquo and you cannot provide evidence against it. Shakespeare uses that to prove that Macbeth’s brain is deteriorating.
Macbeth shows the guilt that he feels after the death of Duncan when he says, Shakespeare uses language to prove how guilty Macbeth feels after the killing of Duncan by over exaggerating the water it would take to  clean Macbeth’s hands from blood. Hence the blood of Duncan is not just on his hands, however, it it is on his heart.

Macbeth
Will all great Neptune’s ocean wash this blood
Clean from my hand? No, this my hand will rather
The multitudinous seas incarnadine,
Making the green one red.

Shakespeare uses rhythm to show the deterioration that characters are having.Normally high status characters will talk in iambic pentameter. Whilst low status characters will talk in different type of rhythm or in no rhythmical pattern at all. Macbeth, the king of Scotland, is supposed to talk in iambic pentameter, and Shakespeare does use iamb for the speeches of Macbeth. However when his wife dies. The woman that he loved for very long. The woman that persuaded him to do whatever she wants. Macbeth’s mental status worsens a lot. This is seen in the way Shakespeare makes him speak.

MACBETH
She should have died hereafter;
There would have been a time for such a word.
To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day
To the last syllable of recorded time,
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!

 This is a great soliloquy because it proves the mental break down that Macbeth has. The broken rhythm shows how the character is thinking about what he wants to say. Broken rhythm is used to show the emotions that Macbeth has. Having a king talk in broken rhythm shows how much deterioration that, not to just the king, but the whole nation. In other words, broken rhythm means broken mentality.
Shakespeare also uses paradox to show Macbeth’s deterioration. In the planing of Duncan’s killing, Macbeth starts getting frustrated. These are the first changes that Macbeth is forcing him self to. After persuading him self. Macbeth says something interesting.
MACBETH
False face must hide what the false heart doth know.
This paradox means, do not show what you have in your heart by the expressions of your face. This is the point where all the hiding of emotions starts. And in this point Isolation starts.
Shakespeare uses Dramatic Irony to prove how Macbeth is a big snake that can not be trusted in the beginning when he says
MACBETH

(aside) The prince of Cumberland! That is a step
On which I must fall down, or else o’erleap,
For in my way it lies. Stars, hide your fires;
Let not light see my black and deep desires.
The eye wink at the hand, yet let that be
Which the eye fears, when it is done, to see.
The (aside) marks that it is dramatic Irony. This is suggesting that has his eyes on the prince of Cumberland because of his ‘black and deep desires’. This proves the witches’ interruption in Macbeth’s morals.
Suspension of disbelief is a powerful tool that Shakespeare uses to enforce the idea of him communicating something to the audience. This magical device is used throughout the play to prove that the writer is the one who is talking. There is a remarkable moment where Shakespeare use the suspension of disbelief technique. When Macbeth’s wife dies, Shakespeare finally makes it clear why he used all of these techniques and language devices.
Macbeth
Life’s but a walking shadow, a poor player
That struts and frets his hour upon the stage
And then is heard no more: it is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
Shakespeare created this character ‘Macbeth’ with all the twists in his morality and the consequences that he had to serve with no choice. The Dire Ambition ideology that shows how some people will do anything to get to their dreams, even if by doing that you are hurting others. Shakespeare
Shakespeare is saying that being rich and owning everything does not mean you will be happy. Depending on the way you get to richness, you’ll seek either happiness or loneliness.

Act 5 Scene 2 to Scene 9 (Macbeth)

Scene 2 starts with lords discussing Scotland and Macbeth, as the English army and the rebels approach with the lead of Malcom. This is when we are introduced to the meeting of the English and the Scottish rebel army’s meeting in near Birnam Wood. We know, from this scene that Macbeth is preparing his army in Dunsinane Castle. The lords show us that Macbeth’s army is fighting not for their king, but because they are forced to fight.

LENNOX

     Or so much as it needs,
To dew the sovereign flower and drown the weeds.
Make we our march towards Birnam.

In scene 3, Macbeth’s keeps making a fuss, next to the doctor, about how he is undefeatable and that he cannot be scared because no one can kill him since everyone is born from a women. Plus that he will be king until Birnam Wood comes to Dunsinane Castle. Seyton, Macbeth’s servant says that an army of ten thousand men are approaching. The doctor then tells Macbeth about Lady Macbeth’s delusions and Macbeth orders him to cure her from them.

MACBETH

I’ll put it on.
Send out more horses. Skirr the country round.
Hang those that talk of fear. Give me mine armor.
In scene 4, the meeting in Birnam Wood starts, and the army leaders decide to cut off trees from Birnam Wood and carry them as they approach Dunsinane Castle so that they disguise their armies number.
MALCOLM

Let every soldier hew him down a bough
And bear ’t before him. Thereby shall we shadow
The numbers of our host and make discovery
Err in report of us.
In scene 5, we are introduced to the death of Lady Macbeth, then Macbeth says one of the most famous Shakespearean soliloquies.
MACBETH

     She should have died hereafter.
There would have been a time for such a word.
Tomorrow, and tomorrow, and tomorrow,
Creeps in this petty pace from day to day
To the last syllable of recorded time,
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life’s but a walking shadow, a poor player
That struts and frets his hour upon the stage
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
This soliloquy shows the sadness of Macbeth, if those news did not scare him, the next news were about Birnam Wood approaching Dunsinane Castle. Macbeth starts panicking because of the news, he tries to make him self confident by saying that at least he will die fighting.
In scene 6 Malcom gives the order to start the attack.
In scene 7 Macbeth keeps killing any one next to him and showing a lack of respect because no one can kill him.
In scene 8, Macbeth has a long chat with Macduff whilst sword fighting and Macduff tells him that he was not born from a women’s vagina however he was surgically removed from his mother, Macbeth then refuses to continue fighting. However Macduff tells him to kneel then and admit that he is not the king any more. Macbeth refuses to kneel and says
MACBETH

     I will not yield,
To kiss the ground before young Malcolm’s feet,
And to be baited with the rabble’s curse.
Though Birnam Wood be come to Dunsinane,
And thou opposed, being of no woman born,
Yet I will try the last. Before my body
I throw my warlike shield. Lay on, Macduff,
And damned be him that first cries, “Hold, enough!”
In scene 9 Dunsinane Castle is captured by the English and rebel Scottish armies. Ross tells Siward that his son died when facing Macbeth. Macduff entres with Macbeth’s head and Malcom is crowned King of Scotland.

Act 5 Scene 1

In this act, the readers witness how a physician and a nurse find out about some dark stuff that they are not supposed to know about Lady Macbeth. Everyday Lady Macbeth goes to a box picks up a letter seal it and then she goes back to bed. The nurse was suspicious so she asked a physicist to watch, and then Lady Macbeth starts talking about death and blood and Banquo’s death, the nurse and the physicist were scared, so they decided to act if they have not seen nor heard anything.

LADY MACBETH

Out, damned spot! Out, I say!—One, two. Why, then, ’tis time to do ’t. Hell is murky!—Fie, my lord, fie! A soldier, and afeard? What need we fear who knows it, when none can call our power to account?—Yet who would have thought the old man to have had so much blood in him.
[…]
LADY MACBETH

The thane of Fife had a wife. Where is she now?—What, will these hands ne’er be clean?—No more o’ that, my lord, no more o’ that. You mar all with this starting.
[…]
LADY MACBETH

Here’s the smell of the blood still. All the perfumes of Arabia will not sweeten this little hand. Oh, Oh, Oh!
[…]
LADY MACBETH

Wash your hands. Put on your nightgown. Look not so pale.—I tell you yet again, Banquo’s buried; he cannot come out on ’s grave.
[…]
LADY MACBETH

To bed, to bed. There’s knocking at the gate. Come, come, come, come. Give me your hand. What’s done cannot be undone.—To bed, to bed, to bed!

Macbeth Act 4 Scene 3

In this act we see how Macduff tries to persuade Malcom to be King of Scotland. However Malcom starts talking about how he would make a bad king and that he has got bad desires. Therefore if Malcom becomes king of Scotland, Scotland will suffer. Macduff then feels really disappointed since he has left his family in Scotland without goodbyes to see someone who deos not want to be a king. However Malcom then says that even though he has these bad desires, he never acted upon them. Therfore he might be a good king. Then the doctor comes and tells Malcom that a crowd of ill people are waiting for a person to heal them. Macduff then asks him who is that person and what does he mean. To the n find out that person is the king of England and that the king of England can cure you from evilness from just telling you. Ross then enters Macduff asks him about Scotland and he replies that everything is upside down and that Macduff’s family is OK. However he tells Macduff that his wife and child were killed by Macbeth. And then all three of them decide to go on war against Macbeth.

MALCOLM

     This tune goes manly.
Come, go we to the king. Our power is ready;
Our lack is nothing but our leave. Macbeth
Is ripe for shaking, and the powers above
Put on their instruments. Receive what cheer you may.
The night is long that never finds the day.

 

Macbeth Act 4 Scene 2

Lady Macduff is worried about her husband’s sudden disappear to England. Lady Macduff does talk to Ross about but Ross leaves her vulnerable to risks. Lady Macduff does question Macduff’s love towards his family since he left the whole family vulnerable to risks knowing that Scotland is not a safe place any more. Lady Macduff then has a really lengthy conversation with her son about traitors and her husband given that she thinks that her husband is a traitor. This conversation ends with the killing of Lady Macduff and her son.

FIRST MURDERER

     (Stabbing him)     What, you egg?
Young fry of treachery!

SON

He has killed me, mother.
Run away, I pray you!
He dies. Exit LADY MACDUFF, crying “Murder!” followed by MURDERERS

 

 

What is Shakespeare trying to communicate about life? “She should have died hereafter.”

MACBETH

     She should have died hereafter.
There would have been a time for such a word.
Tomorrow, and tomorrow, and tomorrow,
Creeps in this petty pace from day to day
To the last syllable of recorded time,
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life’s but a walking shadow, a poor player
That struts and frets his hour upon the stage
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.

Shakespeare in this quote is trying to communicate something really important about life. Shakespeare chooses the right time to deliver this message to his audiences. Macbeth’s wife just died, and Macbeth loves her so much. Just to give you an image of how much Macbeth loves his wife, Macbeth killed Duncan, a king of Scotland, because his wife told him to do it, and he did it even when she did shame him and questioned his masculinity.

This is why the soliloquy “She should have died hereafter” by Macbeth is really important. Shakespeare is not talking necessarily about Macbeth’s feelings now. Shakespeare in fact is trying to communicate a message about life. The first two lines are, “She should have died hereafter. There would have been a time for such a word.” life is too short for a person to cover everything they want to cover in their lives. Essentially Macbeth is saying that he does not have time for sadness. In a sense Macbeth is right because he, the king of Scotland, is in fight with his people and the English army. In other words, Macbeth is saying through Shakespeare’s words that he does not have the time to mourn about his wife’s death. Which does raise suspension, hence Shakespeare is saying that life is short and you cannot do everything you want to, however Macbeth is saying that he does not have time to be sad – If Macbeth dies he will regret not being sad -. And when Shakespeare says “Tomorrow, and tomorrow, and tomorrow, Creeps in this petty pace from day to day To the last syllable of recorded time, And all our yesterdays have lighted fools The way to dusty death.” In these verses, Shakespeare uses the first metaphors in this soliloquy. Macbeth says that every day we spend on our lives, death starts sneaking from day to day until the time has come and that time that was recorded for you is over. Shakespeare might also mean that God and Angeles were recording everything you have done and every syllable you have said. And then Macbeth says: in the past the way to death was obvious and only fools did choose it. In other words only fools die. The metaphors that Shakespeare used are Creeps since death cannot creep, -it is probably personification as well-, and syllable since time is not measured with syllables. Shakespeare also says that life is a brief candle using a metaphor “Out, out, brief candle!” Shakespeare than says that life is just a player that shows off and gets sad for an hour and then no one hears about him. He also says that this is just a tale told by an idiot, we can see the use of the linguistic device of diction since Shakespeare use the word idiot and nothing else to describe him self to the audience. Shakespeare then continues to say that that idiot ,which is him, is just making sounds that mean nothing. This is interesting, hence in the world of Macbeth Shakespeare is God himself. -He creates stuff and removes stuff and know what is in the characters’ minds.- However, if Shakespeare did not mean that verse on this way, he meant it in a way where he says that (these are words used to explain, and I do not agree with them) this tale is told by an idiot, and that idiot is God, that God is just emitting sounds that mean nothing to him. All of these meanings are all combined to make a beautiful soliloquy.

Macbeth’s equivocation

I think that Macbeth is an equivocator. Macbeth shows a lot of equivocation when the corps of the king Duncan are found. The quote is:

MACBETH

Had I but died an hour before this chance,
I had lived a blessèd time, for from this instant
There’s nothing serious in mortality.
All is but toys. Renown and grace is dead.
The wine of life is drawn, and the mere lees
Is left this vault to brag of.
In this quote, we can see how equivocated Macbeth is when he is lying about the killing of Duncan. Macbeth says,” I wish that I died before this event occurred and that would of been blessed for me then this moment. There is nothing that people can live for, everything is just meaningless. That great king is dead. The wine of life is poured out. And only worthless stuff is stuck in there.”
The linguistic device used is “Metaphor”. It is The wine of life is drawn, and the mere lees is left this vault to brag of.” Macbeth is saying that now, life’s wine is poured out and only worthless stuff is stuck in the bottle. What Macbeth means is that life is worthless after the death of the king.

Act 4 Scene 1

I this Scene, we see how Macbeth pays the witches a visit to kind of ask them about the future. The witches as representatives of evil obviously agreed to what Macbeth has asked them to do. The witches decided to give him apparitions. The first Apparition was an armed head, and he said that Macbeth needs to be careful of Macduff (the thane of fife).

FIRST APPARITION

Macbeth! Macbeth! Macbeth! Beware Macduff.
Beware the thane of Fife. Dismiss me. Enough.
The second apparition was a bloody child, and he told Macbeth that no one who is born from a  women can harm him (just a point, a surgery does not count).

SECOND APPARITION

Be bloody, bold, and resolute. Laugh to scorn
The power of man, for none of woman born
Shall harm Macbeth.
The third apparition was a child crowned, with a tree in his hand, and he told Macbeth that the end will be when the Great Birnam Wood to high Dunsinane Hill forest comes near his castle.
THIRD APPARITION

Be lion-mettled, proud, and take no care
Who chafes, who frets, or where conspirers are.
Macbeth shall never vanquished be until
Great Birnam Wood to high Dunsinane Hill
Shall come against him.
The fourth apparition was a display of eight kings that looked like Banquo and his sons, Macbeth obviously disliked that and started getting frustrated.
A show of eight kings, the last with a glass in his hand, followed by BANQUO
MACBETH

Thou art too like the spirit of Banquo. Down!
Thy crown does sear mine eyeballs. And thy hair,
Thou other gold-bound brow, is like the first.
A third is like the former.—Filthy hags!
Why do you show me this? A fourth? Start, eyes!
What, will the line stretch out to th’ crack of doom?
Another yet? A seventh? I’ll see no more.
And yet the eighth appears, who bears a glass
Which shows me many more, and some I see
That twofold balls and treble scepters carry.
Horrible sight! Now I see ’tis true;
For the blood-boltered Banquo smiles upon me
And points at them for his.
He then asks if Lennox has seen some weird girls, and wished upon all the people that trust them hell. (Including himself!)
