2nd round of mice sacrifice!

Today 7 mice were sacrificed with a rat as per schedule.

The tissues from the mice – testis and ovary are collect in Bouin’s solution and allowed to get fixed.

The tissues which were collected last week, which waited till today, getting ‘fixed’ was given to Department of pathology for further processing, paraffin embedding, sectioning and staining. Though they were unhappy about the extra work they got because of our tissues, I am relieved as I don’t have to struggle in my department putting up the lab. More over I don’t have to slog with our assistant professors for the preparation of histological slides.

Out of 7 mice dissected one female mice was concieved and it had 5 intrauterine concepts.

Some of the images taken during dissection are below.

Abdominal exposure of the mice, intestines are out. Working in the area of kidney and uterus in an attempt to isolate the ovary.

This is me and BK sir. We dissected mice in our dissection hall - in the gap between the practical and viva voce for the 1st year MBBS students, 1st sessional examinations are on!

4 Mice died! But Experiment is ON.

It was all fine for the first two days. On the third day I found a female mice dead from the 4 mg group. I took the corpus and dissected it in our department with SK sir. But by the afternoon, it was badly smelling and we could not bear it till we could possibly find its ovaries! And I have no idea where its ovaries were! I got some fat from the omentum about the calculated size of gonad and assumed it as ovary!!

The next day – while taking dissection I got a call – Akka, informed me that another mouse is dead. It was again a female, from the group which received 4mg drug. I discarded the corpus straight away!

The next day – Sunday – after the morning ‘tulu mass session at Milagris’ we entered the animal house taking the name of the god and found a male (8mg group) and a female (4 mg group) dead. I know it is unscientific in any study to discard the corpus without knowing the cause of death.

Since then there are no more casualties.

Today I and BK sacrificed 5 mice (3 male+ 2 female) by simple cervical dislocation. We could identify the ovaries and pancreas which we had difficulties in earlier attempts. I have taken the tissues – testis and ovaries in Bouin’s solution and pancreas and kidney in regular 10% formalin.

The story so far-  all mice were injected with Gemcitabine on 23-11-10.

No. of mice injected with drug	Approximate amount	Mice dead	Date of death	Number of mice sacrificed to be on
				01-12-10	07-11-10	30-01-11
6 male mice	4 mg each			2	2	2
4 male mice	8 mg each	1	28-11-10	1	2
5 female mice	4 mg each	1 1 1	26-11-10 27-11-10 28-11-10	1	1(-1)	0
4 female mice	8 mg each			1	2	1(+1)

We are left with 19-4-5=10 mice.

Next Tuesday – 7 mice are scheduled to die.

I am left with 3 to test the reversibility of the drug later in January.

The histological processing of the tissues have started, we are running a trial, by using human liver and rat spleen. Tomorrow it will take the proper shape. By then I will process the mice tissues and get ready for the sectioning and staining by Thursday.

Will post the photos of mice tomorrow.

Experiment started!

Today we injected the drug!

Some how the department of Pharmacology is persuaded and they agreed to give the aged mice - which they are not using. Yesterday Prof and Head of Pharmacology directed Akka to give the mice. I received 10 male and 9 female Swiss albino mice in two cages. I made the necessary purchasing of diluent for Inj. Gemita - that's NS, with 20 insulin syringes.
Today - with BK sir and Santhosh sir we injected the mice with Gemcitabine and divided them into 2 groups - those which got 4mg and those which got 8mg!

No. of mice injected with drug	Date	Approximate amount	Number of mice sacrificed to be on
			30-11-10	07-11-10	30-01-11
6 male mice	23-11-10	4 mg each	2	2	2
4 male mice	23-11-10	8 mg each	2	2
5 female mice	23-11-10	4 mg each	2	2	1
4 female mice	23-11-10	8 mg each	2	2

Totally 19 mice are subjected to the study and we have diluted the entire drug in the ampule !!
We are left with more than half of the drug - most probably will be discarded tomorrow !

Tomorrow will be posting the photos !

Mice procurement - not so easy!

The department of Pharmacology has established the central animal house and in charge of it. It has taken a heavy toll on the personnel involved in the work, and are in colossal hope of the rewards for their solid work.

From our side – we always are in tough fight against materialistic attitude of the people around us, making fun of people, are using the same material which they are bargaining for their survival! It’s a tough call, but every time an egoistic face will unearth and will wipe the whole idea of collaboration and corporation.

So in these conflicts the idea of whose animal was it, which invariably not going to make up for the race of survival but eventually going to die – will stand as a mockery of all the human efforts on the surface of earth and eruct the walls of hatred for materialistic, mortal men and at the same time, make us feel the eternity of the concept that we are earthly!

Of late we came to know that the people in pharmacology didn’t like the concept of using the animals by us, which they have purchased for money.

I have made a clear notion- that the animals for our experiment will be purchased just as they are doing. Probably that’s the only way of making it.

I also got the clear notification that BK can get away with it. And any irregularity on the part of animal procurement, handling and sacrificing will have a serious face and consequences if unforeseen mishappening occur with me.



Mice work - Yet to start

For various reasons the mice experiments are getting delayed.

1. Our histology lab is not yet funstional - we have ordered for tissue capsules, it is on its way - from past 2 weeks.
2. The rats have become intolerant in BK's experiment - it can no more be fed like the previous one. Thay are totally restless and agitated during every attempt of feedinf oflox. New methods are on cards. Have to implement.
3. Pathology people are more cooperating with us in seeding a lab establishment than in processing the tissue given to them. We are in the mood of having our lab functioning - than to collaberate with them!
4. Of late - a cold war has started - with us and Pharmacology department - sparked by uninformed use of one more rat for the oflox experiment. We have given lengthy request letter for more rats and mice. Finally they made the comment, much inevitable - 'we dont have enough male mice, you may have to order'. This may have more impact in future than it is evident today!

From today we have started writing in a movememt kind of register in the central animal house, indicating the time of visit, the purpose of visit, the persons visited to the central animal house.
Some how we have to see that some staff member is present whenever we goto animal house, so that any mishappenings can be overcome easily! and my senses are telling that the animal house is not all that fool-proof.
