[Toshiba]

I think The answer to the Q.Increased sussep. to inf. is Gardners Syndrome but some should reconfirm.

 

[TEJU]

hi
the answer is basophilia cos the erythroblast is strongly basophilic
if it were asked to mature erythrocytes then it the answer wud b acidophilic
cos an erythrocyte is an acidophilic rbc.

2nd one is
i guess hypertrophy and maturtion
the chondrocytes are swollen prior to apoptosis n replacement by ostoeblats


3rd
TCA

correct if m wrong

Cytologic changes during development of erythrocytes. Stages are:

1.PROBASOPHILIC ERYTHROBLASTS (proerythroblast, pronormoblast, rubricyte) : 15-20 µm diameter, BASOPHILLIC cytoplasm, large nucleus, finely granular chromatin, prominent nucleoli.

2.Basophilic erythroblast (basophilic normoblast, prorubricyte): 12-16 µm diameter, deeply basophilic cytoplasm, nucleus smaller, with coarsely clumped chromatin, no nucleoli.

3.Polychromatophilic erythroblast (polychromatophilic normoblast, rubricyte): 10-12 µm diameter, cytoplasm varies from blue-gray to slate-gray. Nucleus small with a denser more compact chromatin structure.

4,Normoblast (acidophilic erythroblast, acidophilic normoblast, metarubricyte)
ACIDOPHILLIC ERTHROBLAST: 8-10 µm diameter, small pyknotic nucleus, acidophilic or slightly greyed cytoplasm.

5.Reticulocyte. Slightly larger than mature erythrocyte, acidophilic cytoplasm contains remnants of ribonucleoprotein stainable as a network or web.

6.Red blood corpuscle.

So, answer as to be basophillic. (proerthroblast to erythroblast is basophillic to acidophillic).

3 QNS:B-oxidation is another name for fattyacid degradation.

hope I'm right.

well as far as my knowledge goes
answer to first is
periosteum

answer to 2nd is
gardner's syndrome
coz syptoms of gardner's symptom are
multifocal pigmented lesions,osteoma,supernumerary cysts,intestinal polyps,dermoid /epidermoid cysts
due to GI polyposis ppl are very susceptible to infections

answer to 3rd q's
is vagus nerve

 

[rtvj]

Hi

1st question-codominance is right.

Answer for 2nd question is Ig E..becos in Glomerulonephritis,one can see granular deposits of IgE and C3 in the Glomerular Basement Membrane.

dunno answer for 3rd q.

Protooncogenes are oncogenes which control cell proliferation.

pls correct me if wrong.

1 The atrioventricular valves r closed during
PR interval
ST interval
qrs interval

can u pls tell me with reason.
thanx in advance.

hi!
i think the answer is qrs interval

'coz av valve closure occurs when ventricular diastole is over i.e at the beggining of ventricular systole.

for ventricle to contract ventricular muscle shud depolarize which is nothing but the qrs interval(which means ventricular depolarization prior to contraction)

do correct me if i am wrong 🙂

The av valves close at the QRS complex,since that is when the first heart sound is heard as well as this is the period of ventricular depolarization or systole...
Hope this helps u..

[jimmyhere]

Anyone.....

 

[rtvj]

check out this site for info on septic arthritis.

http://www.hmc.psu.edu/healthinfo/s/septicarthritis.htm

Prozone:

In an agglutination or precipitation reaction, the zone of relatively high antibody concentrations within which no reaction occurs is called prozone. As the antibody concentration is lowered below the prozone, the reaction occurs. This phenomenon may be due simply to antibody excess or it may be due to blocking antibody or to nonspecific inhibitors in serum. Called also prezone.

Septic Arthritis in adults is a sexually transmitted disease, esp among homosexuals.and Gonococci is one of the causative agents.
In children it is caused by Staph.

if u go on this link u will see that during ST segment Av closes and only opens later. during rapid ventricular ejection mitral is closed which corresponds to St segment

 

[NASA]

hi,
can someone explain wat exactly does plasma colloid pressure or osmotic pressure means.....coz the more i read abt them the more i get confused and abt the interstitial pressure too.....

thx in advance........
cheers...........

 

[anjali_45]

net filtration pressure is
(Pc-Pi)- pi c-pi i
where pi is protein osmotic pressure
which is roughly
45-10-28-0=7

 

[anjali_45]

The characteristic color of the pus is due to a bluish pigment (pyocyanin) and a greenish pigment produced by pseudomonas.

 

[anjali_45]

Plasma COP is generated by the plasma proteins, particularly albumin, Lower plasma COP favors a fluid shift from intravascular space into interstitial space, with subsequent formation of peripheral and pulmonary edema To stabilize the intravascular volume and prevent or reverse the events leading to peripheral and pulmonary edema, albumin or other colloid solutions are frequently administered, to maintain the COP in the 'normal' range .


Interstitial fluid

Interstitial "fluid"- complex structure.
Mixture of glycoproteins, glycosaminoglycans and hylauronate linked together to make a solid matrix entangled in a network of collagen fibres. The matrix takes up free fluid forming a gel. This fluid is the interstitial fluid.
Bulk flow of fluid through the interstitial spaces is inhibited by the structure of the gel.
The gel gives the organs and tissues of the body their characteristic shape. Diffusion through the gel is almost as fast as it would be in free solution, but the gel itself protects the organs and tissues against changes in shape due to gravity and other forces.
Negative fluid pressure


Think "Freeze dried coffee"
The fluid pressure within the gel is slightly negative. This means that the cells of the tissue are sucked together and the connective tissue binds firmly round them retaining the relatively rigid shape, rather like polystyrene balls in a plastic bag from which some air has been removed to make a partial vacuum.



There is slightly more filtration than reabsorption as the blood passes through the capillary. In addition there is some small leakage of colloids.
This excess fluid is returned to the circulation, together with the leaked protein, through the lymphatics.
Lymph flow increases during exercise as increases in perfusion pressures and in the number of open capillaries lead to an increased rate of fluid filtration.



Factors Affecting Fluid Exchange Across Capillary Walls

The net rate of fluid movement across the capillary wall is given by the following equation:
Q = K [(Pc - Pif) - (Pp - Pif)s]
Where
Q ml/min is the net rate of capillary filtration

Pc is the capillary hydrostatic pressure (mm Hg)

Pif is the interstitial fluid hydrostatic pressure (mm Hg)

Pp is the plasma colloid osmotic pressure (mm Hg)

Pif is the interstitial fluid colloid osmotic pressure (mm Hg)

s is the reflection coefficient for the colloids at the capillary membrane

K is the hydraulic permeability of the capillary wall (ml/min/mmHg)

1. The most common etiologic agent of septic arthritis in adults is

a. Neisseria gonorrhoeae-----> correct
b. Hemophilus Influenzae
c. streptococcus Pyogenes
d.streptococcus pneumoniae

Ans:Non-gonococcal septic (bacterial) arthritis
Septic arthritis may be seen at any age. In children, it occurs most often in those less than 3 years old. The hip is a frequent site of infection in infants.

Septic arthritis is uncommon from age 3 to adolescence, at which time the incidence increases again (appearing as gonococcal arthritis in females with cervical gonorrhea).
Children with septic arthritis are more likely than adults to be infected with group B streptococcus and Haemophilus influenza.

Acute septic arthritis tends to be caused by organisms such as staphylococcus, streptococcus (pneumoniae) and group B streptococcus Chronic septic arthritis (which occurs less frequently) is caused by organisms such as Mycobacterium tuberculosis and Candida albicans. The knee and the hip are the most commonly infected joints.

3. In amyloidosis of the tongue , the amyloid is deposited mainly in the

a. stromal connective tissue
b. cells of the surface of the epithelium
c. newclei of the striated muscle cells
d. Acinar cells of the glands of the tongue

Ans: NUCLEI OF STRAITED MUSCLE CELLS
1.TONGUE: prominent deposition of amyloid substance in the subepithelial and striated muscle tissue.
2.Esophagus, stomach and intestines: diffuse and patchy deposition of amyloid substance mainly in the smooth muscle layer but also in the muscularis mucosae and submucosa of those organs.
3.Lungs: diffuse amyloid deposition in the walls of the blood vessels of various diameters in the interstitium and in the thickened alveolar septa.
4Spleen:Amyloid substance is deposited along the trabeculae.

4. what is the prozone?
Prozone phenomenon is seen with syphilis and HIV-1 co-infections.
I'm n't sure.

5.micro organisms characteristic of ehich of the following infections require a specific receptor site to infect the host.

a. anthrax
b. cyphilis
c. influenza -- correct
d. dysentery

Ans:Influenza virus hemagglutinin (HA) mediates virus entry into a host cell through two functions, receptor binding and membrane fusion. Hemagglutinin(HA) is influenza's receptor-binding protein that helps the virion get into host cells and neuraminidase (NA) is an enzyme that helps the offspring virions to get out. Together, these two viral proteins are primarily responsible for the viruses' ability to cause disease.

well as far as my knowledge goes
answer to first is
periosteum

answer to 2nd is
gardner's syndrome
coz syptoms of gardner's symptom are
multifocal pigmented lesions,osteoma,supernumerary cysts,intestinal polyps,dermoid /epidermoid cysts
due to GI polyposis ppl are very susceptible to infections

answer to 3rd q's
is vagus nerve

hi...
i think the answer is hypopitutarism.
polyps can turn cancerous.. but not too sure about suspectibility to infections.

]1. Maxilalry facial mandibular lingural cusps require sifficient occlusal length and horizontal pverlap for
1. esthetics
2. centric stability
3. chewing efficiency ANS: 4
4. soft tissue protection
5. none of the above
these r the guiding cusps which protest the adjacent tissues from damage[max facial -the cheeks and the mand lingual the tongue]

2.In an ideal occlusal relationship, when an exaggerated Bennet component is present in lateral jaw movement, it will have it's greatest potential for interferance with the
1. Mesiodistal positioning of cusp tips
2. buccolingual positionaing of cusp tips
3. position of the central fossa
4. depth of the distal fossa
ans-1[given in decks]

3. The Dryopithecus pattern shows up most clealy in the
1. maxilalry canine
2. maxillary third molar
3. mandibular first molar
4. mandibular first premolar
ans-3[it is the Y5 dental pattern for 5 cuped teeth so 1st molar]

4. Dentin "islands" are frequently found in the root canals of which of the following permanent teeth?
a. Maxillary lateral incisor
b. Maxillary second premolar
c. Maxillary first molar
d. Madibular canine
e. Mandibular second premolar

1. a and d
2. b and c
3. b and d
4. c and e
5. d and e
ans-3[these r found in teeth with wide faciolingual but narrow MD dimension of root canals]


5.Which of the following is true regarding maxillary molars?
1. Are set somewhat lingual to the premolars
2. Show a convergence of their buccal surfaces mesially
3. By their arrangement and design allow room for the powerful masseter muscle. ANS: 3
4. Curve inward more sharply from the medical plance on the buccal than to do the mandibular molars.
[this one i still dont get it]

6. the terminal hinge axis is the center of rotation for the mandiable when it opens from which from the following positions
1. Rest
2. Edge-to-edge
3.Retruded contact
4.Maximum protrusive
5. Maximum intercuspal
ans-3or centric relation [CR-from this position the condyles open&close without translation and hinge axis movement is movement without translation]

7.When viewed occlusualy, the aveoli of which of the following groups of teeth tend to be aligned nearest to a straight line?
1. Right and left maxilary central and lateral incisors
2. Right and left mandibular central and alteral incisors
3. Maxillary and left mandibular central and lateral incisors
4.All amxillary first premolars and first molars
5.All mandibular anterior teeth.
ans-2[why no idea]

8.Which of the following is NOT normally an alterable factor in the articulation of teeth?
1. incisal guidance
2. Postural position
3. compensating curve
4. cuso-fossa relationship
5.posterior tooth morphology
ans-2

a. On the distal, it is more apical than on the mesial
b. On the lingual, it is more incisal than on the facial
c. On the mesial, it is more apical than on the distal
d. on the facial, it is more apical than on the lingual
e. On the facial and the lingual, it is at the same level[/QUOTE]
ans-1[i guess becoz distally there is a deep concavity just above the cervical line in LI ]

hi...
i think the answer is hypopitutarism.
polyps can turn cancerous.. but not too sure about suspectibility to infections.

I think you are correct. I did some research over the net and I could not find anything about relation between Gartner syndrome and increased suspectability to infection.
However, if it is HYPOpituitarism that could cause Addison disease (low ACTH hormone production) and one of the complications of Addison disease is the Addison Crisis which is could be caused by an infection as FLU.
Let me know if I,m wrong. 😎 😎

a. maxillary canine and first premolar

b. mandibular lateral incisor and canine

c. maxillary lateral incisor and canine

d. mandibular central and lateral incisors

e. maxillary central and lateral incisors

But in 1 place it was given A as the answer and somewhere else it was C.that is why i asked which is the right answer....?
