correction in 7 pages u must correct the original note. That begin from page 8 to the last. U must study original one firstly

فقم بتصحيحيها من هنا. 8ة الاصلية اولا والتى تبدء من صفحة يقع التصحيح اولا من حيث الترتيب لكن لابد من مذاكرة الملزم

Questions that I am very sure about it I already correct it.

Those that I am not sure just write their numbers.

6- this question and number 421 need confirmation.

7- false. As insulin dec TG synthesis.

1

about 36hrs (11/2 day) & ultra lente. Ultra lente from 18

to 24 hrs not 36 hrs

g/day ; not to exceed 2 g/day

Maybe correct, not sure.

547- INH cause gynecomastia in very rare condition.

Drugs causing Gynecomastia :

1 Digitalis (due to steroid structure)

2 Spironolactone (due to steroid structure)

3 Reserpine

Due to decrease dopamine in CNS increase prolactin

4 α-methyldopa 5 Ketoconazole (antifungal, decrease synthesis of androgens) 6 Cimetidine (H2-blocker, used in the treatment of peptic ulcer, causes antiandrogenic action) 7 Estrogen (given to males for treatment of cancer prostate)

626 - not sure about :

b-fasten transfer of fertilized ovum

others r right.
