    1 E true because thiamine is involved in TCA Cycle
    3 C true D false
    4 B false

    rest of aminas agreed.

    a. common site is sigmoid
    b. agreed

    hi,

    20. F TFFF ----c-? do u think f.could u explain.

    21. BF TYPE 2---agreed,i think a-f,any comments.

    23. D R U SURE---i think -f

    24. AF ---agreed
    C T----false,its only in brain we have colliquative necrosis,other organs it is coagulative.

    25. E R U SURE ABOUT THIS? ---e-t

    27.TTTTT--agreed

    28. E T ---agreed

    29. F T F T T --agreed

    30. T T T T T ---e-f,i think if it were to be chronic asthma i would have said true,since its just bronchial asthma,i will say false----any other comments pls.

    32. TTTFT---agreed
    33. D F? ---d-t
    34C T ---agreed


    37.T F T T F --agreed

    38. B T--agreed,but a-f

    40-e i think its true,since there is no proper excreation it further obstruct the conjugation.

    hi nivitha

    32. adeno ca colon

    a. common site is sigmoid---60-70% located in the rectum and sigmoid colon. However, the incidence of carcinoma of the right colon is increasing .Over 95% are adenocarcinomas,so its true.
    b. agreed
    c. agreed

    33. D. increased capillary fragility comes in scurvy not in rickets. may be u r right but iam not sure either.

    27.TTTTT--agreed....................no i think it is fttft

    40-e i think its true,since there is no proper excreation it further obstruct the conjugation......................false.there is a problem down in the bile.so there will not be a problem in the unconjugated being converted to the conjugated sine it occurs in the liver.it is that it cannot enter the bile duct so it cannot be excreted as urobilinogen or stercobilinogen

    hi,

    could u give me reasons for 27.

    q40 i agree with u,they will have conjugated hyperbilirubinemia.(thanks)

    nivhitha Guest

    almost all cancers in the colon are adenoca irrespective of the site. rarely sq. ca occurs. the commonest region is the rectosigmoid/sigmoid regions.
    though the right sided cancers are increasing, still rectosigmoid continues to be the commonest site.


    In acute biliary ostruction, conjugation IS not impaired. only in chronic biliary stasis is conjugation impaired

    yes nivhitha,u r right with ur explanation.

    17 d What genes are related to cystic fibrosis?
    Mutations in the CFTR gene cause cystic fibrosis.

    The protein made by the CFTR gene forms a channel that controls the movement of salt and water into and out of cells. Mutations in the CFTR gene alter this protein in such a way that the channel is blocked. As a result, cells that line the passageways of the lungs, pancreas, and other organs produce abnormally thick, sticky mucus. This mucus obstructs the airways and glands, causing the characteristic signs and symptoms of cystic fibrosis.

    Other factors likely influence the course of the condition. For example, changes in genes other than CFTR might help explain why some people with cystic fibrosis are more severely affected than others. Most of these genetic changes have not been identified, however.

    Q 27, A, D, should be False as Hydronephrosis is mechanical obstruction and according to Robbins pathology the main causes for it is :
    1.Congenital anomalies: posterior urethral valves and urethral strictures, meatal stenosis, bladder neck obstruction; ureteropelvic junction narrowing or obstruction; severe vesicoureteral reflux
    2.Urinary calculi
    3.Benign prostatic hypertrophy
    4.Tumors: carcinoma of the prostate, bladder tumors, contiguous malignant disease (retroperitoneal lymphoma), carcinoma of the cervix or uterus
    5.Inflammation: prostatitis, ureteritis, urethritis, retroperitoneal fibrosis
    6.Sloughed papillae or blood clots
    7.Normal pregnancy
    8.Uterine prolapse and cystocele
    9.Functional disorders: neurogenic (spinal cord damage) and other functional abnormalities of the ureter or bladder (often termed dysfunctional obstruction)

    CREATININE

    creatinine has a plasma clearance rate eqivalent to renal plasma flow.T
    PLZ COMMENT
  22. mrcog guest

    mrcog guest Guest

    march 1998 paper2

    renal plasma flow is measured using PAH.it is 625 ml/min.
    GFR can be measured using creatinine clearance.and is about 125ml/min.

    so,it is false.

    thanx mrcog guest
    i was confused now its clear.its GFRTHAT CAN BE MEASURED BY CREATININE CLEARANCE.
