which of following is not correct about interleukins?

1. IL-5 is produced by activated T helper cells and mast cells.
2. IL-3 is secreted by T helper cells and mast cells.
3. IL-8 is secreted by monocytes and macrophages.
4. IL-10 is produced by activated T cells and mast cells
5. IL-7 is secreted by bone marrow stromal cells.

(reference from Kaplan Dent essentials:

IL-5 (source) TH2 cees
IL-3 TH cells, NK cells
IL-8 Macrophagess, endothelial cesss
IL-10 TH2 cells
IL-7 Primary lymph organs (so this one should be correct answer)?

Each of the following DNA virus encodes a DNA polymerase except one, which is this exception?

1. Hepatitis B virus(yes for polymerase)
2. SV40
3. Adneovirus (No)
4. EB Virus (No)
5. Poxvirus (yes for polymerase)

which one should be the right answer?

Should be B, I think since decreased O2--increase the H+, tissue should be diated to get more o2. constrict the vessel will increase the damege to the tissue.

please correct me if i am wrong

i thought that constriction of coronary arteries was right coz it ll cause decrease blood flow to other parts of body and keeps more blood in heart and increase oxygen tension in myocardium..

any more suggestions?

the key is A, urea. that means the hepatic function is ok and can still synthsize the urea

ya it was a mistake ..agree with the answer B coz as coronary arteries supply blood to heart, increased blood flow required to increase oxygen tension...hence vasodilation..

no hinge axis movement occur during jaw opening just rotation or forward translation
but Bennet movement occur in lateral movement

The bodily lateral movement or lateral shift of the mandible during a laterotrusive movement.

Mandibular lateral translation (Bennett movement) occurs during the
A earliest stage of lateral movement.
B. latter stage of protrusive movement.
C. middle stage of retrusive movement.
D. hinge axis movement of the mandible.
E. ending stage of exhibiting a border movement.

If you think of it carefully, you will understand that the translation occured in the early stage of the lateral movement.

Hinge axis movement of mandible occurs when you open the mouth and the condyle goes mostly rotation.
