The most important complement-derived chemotactic factor

for neutrophils is:

C1

C3a

C4

C5b67

Histologicallywhich pairs are similar?

Coagulative Necrosis - Liquefactive Necrosis

Caseation Necrosis - Coagulative Necrosis

Gummatous Necrosis - Liquefactive Necrosis

C5a
C5b67

C5a is one of the most potent chemotactic factors known for inflammatory cells.20,21 Recently, specific C5a receptors (CD 88) have been characterized on human neutrophils41 and eosinophils.42 In human mast cells, C5a has been shown to induce histamine release from skin and heart mast cells,24-27 but not from lung mast cells.24 A recent study by Füreder et al43 using indirect immunofluorescence has shown the expression of C5a receptors on skin and heart mast cells, as well as on HMC-1 cells, but not on lung, uterus, and tonsillar mast cells. This mast cell heterogeneity regarding anaphylatoxin-induced activation might be of particular clinical relevance. In contrast to the well-defined biologic effects of C5a on many different cell types, little is known about the effects of C3a. Specific activation by C3a has been shown primarily for guinea pig platelets,14 guinea pig macrophages,44 human basophils,23,45 and human eosinophils.22 In addition, C3a has also been reported to induce histamine release from human skin mast cells24,26,43 and peritoneal rat mast cells.27,46

i think C5a is ans

Histologicallywhich pairs are similar?

Coagulative Necrosis - Liquefactive Necrosis

Caseation Necrosis - Coagulative Necrosis

Gummatous Necrosis - Liquefactive Necrosis

Caseation Necrosis - Liquefactive Necrosis

Caseation Necrosis - Gummatous Necrosis

thanks for the answer friend

i think hageman is right becos it is a clotting disord ,how abt pul thromoembolism r u sure it is sudden death ?

sudden death lock kiya jaya?


The lesion of reinfection, reactivation, or adult tuberculosis

characteristically begins in a:

A. major bronchus

B. hilar lymph node

C. random subpleural

D. subapical region of a lung

E. lower lobe of the lung

1.Sudden Death,lock karo
2.subapical region of lung(normally reactivates in the upper lung becos of high oxygen tension,due to decraesed pulmonary circulation)

pls correct me

i think ans for 1 is T lymphocyte as it mainly fight against virus, mycobacterium& fungi.

ans.d
pls answer

ans....
2.a --both the lingual & inferior alveolar nerves are located superficially
3.d --cementum is supposed to be an avascular tissue,if i remember
4.d --because the other 3 options aren't possible


ans for the 1st one,i'm not sure too...havent heard of "eleiden" what is it ? .epidermis also lacks blood supply.the blood capillaries are present only beneath the epidermis.it derives the nutrients only from dermis..

-well this is what i think.....pls correct me if i'm wrong .

lingual is the answer ,everythin u said is pefect , eleidin is seen in stratum lucidum , it is a factor for growth of epidermis .

all the answers u said r right 👍
