Surprising Effects of Allergy Drugs

A study showed that over the counter allergy drugs reduced the level of hepatitis C virus in affected mice. A drug named chlorcyclizine HCL (CCZ) is presently being tested in chronic patients with hepatitis C. You should be knowing that in Hepatitis C a virus attacks the liver of affected person. People who get affected by Hepatitis C virus develop about 80 % infection in their body. Their body become incapable of getting rid f the virus and the illness becomes chronic. If left untreated it can lead to liver cancer and several other liver problems.

It is estimated that around 185 million people all around the world are affected by chronic Hepatitis C. Today also there is no vaccine to prevent this infection. However, treatments are available for this chronic illness. The only demerit is that the treatment is very expensive. A single medicine can cost thousands of dollars. Scientists are trying to develop a way to find out affordable and effective treatment methods, but no success has been achieved in this field. The researches helped identify multiple allergy relieving antihistamines that also help with antiviral activity.

The drug also inhibited the HCV infection caused in human liver cells. Mice implanted with human liver cells also showed inhibition of HCV infection. That mouse was treated for about 5 to 6 weeks and the virus level was significantly reduced. Steps are taken further to develop an effective method and drug. A vaccine would be best, but no clues are available yet.

Nerve Pathways Repaired By 3D Printing

Recently 3D printing was used to treat damaged rat nerves. It helped produce custom scaffolds which helped the rat improve his walking ability. This study has put some light on the process of making customized scaffolds some day for tissue regeneration. Peripheral nerves are those that spread from our brain and spinal cord to the rest of the body. Damage can be caused to them in various ways. Traumatic injuries, some kind of disease or many other reasons can lead to their damage. Depending on the specific type of injury, treatments are available today for it.

Nerve development is not that simple as it sounds. Many chemical and physical prospects need to be taken in to consideration while developing nerves. Presently the treatment involved taking a certain part of healthy tissue from another part of the body and using it in the place of affected nerve. Harvesting surgery, that is graft is a way limited by size and geometry of nerve. This procedure can lead to several other problems in the host place. Problems can include sensory loss, chronic pain, harmful immune response, etc

A team studying this procedure conducted an experiment on rats. They used 3D light scanning method to prepare a cast of nerves. The conventional imaging technology used can prove to be very helpful in future. Still nothing is sure enough and is not employed on humans yet. With time this process can be checked on humans.
