DIALYSIS
It is a
short term solution to renal failure. Artificial kidney is normally
used for only 4 to 6 hours three times a week. Therefore, the
over all plasma clearance is still considerably limited. When
the artificial kidney replaces the normal kidneys. Not only
is dialysis expensive, but it severely restricts the activity
of an individual. Because a single healthy kidney can meet the
excretory needs of the body, a more permanent solution is the
transplantation of a kidney from the healthy donor.
TRANSPLANTATION
A successful
transplant means that the recipient is cured of renal disease
but there are some drawbacks. Even organs from closely related
donors may be rejected by the recipients immune system. To reduce
chances of rejection, the recipient must be treated with immunosuppressive
drugs, and such drugs not only increase susceptibility to infections,
but may be directly toxic to the liver and bone marrow (Smith
1978).
Since dialysis and transplantation have got their own limitations
and draw backs, search for new medicines, which cures kidney
ailments without any side effects still continues.

ACUTE NEPHROTIC SYNDROME
This is characterised
by haematuria, blood cell casts, proteinuria, Oiiguria, hypertension,
fluid retention and some times renal failure.
The most common cause is the glomerulonephritis caused after
the infection of
Streptococcal, Staphycoccal, Pneumococcal bacterias and other
viral infections. It is also
caused by various other disease like system lupus erythemalosus
(red patches spread
through at the body) and polyarteritis nodosa (Inflammation
of the walls of the arteries)
etc.
The illness starts two or three weeks after the bacterial (Streptococcal)
infection of the skin throat or respiratory tract. It is more
common in children but it can occur in any age. Sudden puffiness
of the face, oliguria, reddish urine hypertension and edema
occur. Severe cases are life-threatening leading to many other
complications.
(i)
NEPHROTIC SYNDROME
It is characterised
by high protenuria (3.5g in 24hrs and in adults and more than
2g/m body surface in children). Consequence of this hypoalbuminuria,
hyperlipidemia and lipiduria (fat in urine) ocurs. Edema is
also present.
The causes
are attributed to glomerulonephritis, glomerulosclerosis, diabetic
nephropathy, systemic lupus erythematosus, kidneys filled with
wax like protein (renal amyloidosis)use of some drugs, gold
salts, mercurials, allergens, beestings, secondary syphlis,
leprosy, infective endocarditis, certain type of malaria (Quartan
malaria) hepatitis B virus, Hodgkin's disease. Multiple myeloma,
lymphatic leukamia, bronchogenic carcinoma suckle cell anaemia,
hereditary nephritis and some times even pregnancy.
The glomerulonephritis in this case is caused by the body's
immunology itself. The antigen and antibody produced against
it combine to form the immune complex. When this immune complex
is deposited in the glomeruli it activates the complement system
This leads to Inflammation, increase in the permeability of
filtering mechanism polymorthonuclear infiltration and other
changes. The inflammatory reaction lead to various types of
glomerulonephritis.
Patients with nephrotic syndrome are susceptible to bacterial
infection, skin infections and pneumonia. Hypertension should
be controlloed.
