An Indian origin doctor, Dr. Hemant Thatte developed a 21-chemical solution known as SOMAH Solution that could preserve a donated organ for up to a week before a transplant.
- Dr. Hemant Thatte is a senior cardiovascular surgeon at HarvardUniversity.
What is SOMAH Solution?
SOMAH Solution in Sanskrit means elixir of immortality.
- The new preservative that is a mixture of 21 chemicals, has the potential to store the heart (and other organs) for up to 7 days.
- A research paper published in the medical journal Circulation in October 2009 showed cells of organs preserved in SOMAH had a lower rate of death than in another preservation solution.
- The biggest advantage of SOMAH is that it can be used at room temperatures.
Presently, hearts and lungs need to be transplanted within 4-6 hours of being recovered from a brain-dead donor, the liver within 8 hours and kidneys within a bit more than 24 hours. In addition, the available organs cannot be transported long-distance for transplant and have to be made available locally.

Dr. Michiaki Takahashi (85), a Japanese virologist, who developed a vaccine for the chicken pox virus passed away. Dr. Takahashi developed his vaccine by growing live but weakened versions of the virus in animal and human cells. The disease was not sourced by the vaccine, but the vaccine encouraged immune system to create antibodies. Thus, it fools the immune system into thinking that it has seen this disease before.
About Chicken Pox
- Caused by the Varicella-Zoster Virus (VZV) which is a form of herpes.
- Highly contagious disease that is spread via contact with infected person.
- Symptoms: rashes in the body, fever, loss of appetite, headache and tiredness.

Chickenpox is caused by the varicella-zoster virus, a form of herpes. If a person contracts the virus, has an active infection and then recovers, the virus is not actually gone from the body. It can hide in nerve cells for years or decades, then emerge again to cause shingles, a painful condition that causes a skin rash and occurs mostly in adults.
