Abstract
Background: Previous studies have shown that human bile contains one or more factors that inhibit the precipitation of calcium carbonate from supersaturated solutions of calcium chloride and sodium bicarbonate. Lower concentrations of this factor have been observed in the gallbladder bile of patients with calcified gallstones. We hypothesized that gallbladder bile contains factors that inhibit calcium carbonate and these factors are present in varying concentrations in normal persons and in patients with cholesterol gallstones with and without calcium carbonate.
Methods: Gallbladder bile of patients without gallstones (n = 8) and of patients with cholesterol gallstones containing either calcium carbonate (n = 8) or other calcium salts (n = 8) was assayed for calcium carbonate inhibition. Individual components of bile (bilirubin, phospholipid, bile salts, and albumin) were tested in different concentrations in the same assay system. In addition, samples of model bile were tested.
Results: An inhibitory factor for calcium carbonate precipitation was present within all human gallbladder bile, irrespective of the absence, presence, or type of gallstones. The addition of a bilirubin-albumin solution to a supersaturated solution of calcium chloride and sodium bicarbonate entirely blocked precipitation of calcium carbonate from solution. In addition, serial dilutions of bilirubin exhibited a linear response between bilirubin concentration and inhibitory effect. Model bile and phospholipid dissolved in sodium taurocholate also exhibited a modest inhibitory effect on calcium carbonate precipitation.
Conclusions: We conclude that bilirubin, cholesterol, and phospholipids incrementally interfere with calcium carbonate precipitation in supersaturated solutions through the preferential formation of a soluble calcium complex.
The organ that is the first site of chemical digestion.
Answer:
The stomach
Explanation:
The stomach is the first place because your mouth and saliva do not do a chemical digestion, it only primes it for the chemical digestion in the stomach, plus the mouth is not a organ, it is a body part, for example the tongue or esophages are organs.

Q.162.A 10 years old girl presented with fever and bruises for last 2 weeks. On examination she is pale; however there is no evidence of lymphadenopathy or hepatosplenomegaly. Her Hb is 6g/dl, TLC is 2700 and platelets are 90000. The most appropriate investigation to clinch the diagnosis is:
a)Bone marrow aspiration
b)Retics count
c)Bleeding time
d)PT and APTT
e)Factor VIII assay
Answer:
In a bone marrow aspiration, a health care provider uses a thin needle to remove a small amount of liquid bone marrow, usually from a spot in the back of your hipbone (pelvis).
A normal PT with an abnormal aPTT means that the defect lies within the intrinsic pathway, and a deficiency of factor VIII, IX, X, or XIII is suggested. A normal aPTT with an abnormal PT means that the defect lies within the extrinsic pathway and suggests a possible factor VII deficiency
Bleeding time is a medical test done on someone to assess their platelets function. It involves making a patient bleed, then timing how long it takes for them to stop bleeding using a stopwatch or other suitable devices.
