Book Mark Widget

I was searching in the internet for a book marking tool that will allow the users of my blog to submit each and individual url of my blog to many bookmarking sites from the site it self. But I couldn't find any. So decided to create it my self. You can see the code below. If you want add it to your own blog and enable your users to book mark individual urls with out any prob. It will automatically generate the url and title of the page, so the users don't have to worry about typing them into the bookmarking site. It will be automatically inserted into the bookmarking site






click on the text area and right click. then select copy from the menu and paste it into your webpage html in an appropriate place. If you have problems just let me know. I can give you a hand.

Action of leukocytes

Just found an amazing work of art and science produced by Biovision, University of Harvard. This is just quite amazing. It explains the processes within the cell. most importantly the underlying processes of leukocyte - endothelial adhesion. This is just great. No words to describe it. Great work.


Hypersensitivity Reactions

Hypersensitivity is an inappropriate immunological response to an antigen that can cause tissue damage. As we know immune response is there to protect us from any foreign antigens ( antigen is a foreign substance that can bind with components of the immune system / Or it can be defines as any substance, against to which antibodies are formed. ex: viruses, bacteria, parasites, toxins). Not only infectious things but also non infectious particles like duct, pollen can act as antigens.


There are four types of Hypersensitivity reactions,


1. Type I hypersensitivity - Immediate hypersensitivity (anaphylaxis)

2. Type II hypersensitivity - (Autoimmunity)

3. Type III hypersensitivity

4. Type IV hypersensitivity - Delayed Hypersensitivity

Poisonous Snakes

Pair of venom producing glands are found in all the poisonous snakes, which are positioned below and behind the eyes. They are accompanied by a pair of maxillary teeth called fangs.



We can identify two types of venom producing glands.

1. True Venom

Elapids, Viperids and sea snakes have this type of venom glands. The fangs are situated anteriorly.

2. Duvernoy's glands

Found in some Colubrids. Relatively small gland situated posteriorly. Venom is ejected through a posterior fang. Colubrids with well developed Duvernoy's glands are mildly poisonous.
