Brief resume of intended work

Need of the work

Urolithiasis is the third most common disorder of the urinary tract. The worldwide incidence of

urolithiasis is quite high and in north India more than 80% of urinary calculi are calcium oxalate

stones alone or calcium oxalate mixed with calcium phosphate 1.

Hyperoxaluria is the main initiating factor of human idiopathic calcium oxalate (CaOx) stone

disease. Oxalate is a powerful crystallization-driving factor present in the urine. Retention of which

enhances cell injury and causes early stages of lithogenesis 2.

Current strategies in treatment :

Surgical and other procedures: surgery is recommended for patients with severe pain who does

not respond to medications, for those with serious bleeding, and persistent fever, nausea, or

significant urinary obstruction. If no medical treatment is provided after surgery, stones reoccur in

50% of patients with in five years.

Hence the present study is designed to evaluate the anti-urolithiatic activity of extracts of wood bark

of Mimosa pudica.

Review of Literature

Anti-urolithiatic agents are used to reduce / dissolve the kidney stone precipitates, caused by

chemical, crystalline and amorphous substances. The deposits may originate from the blood cells or

from the renal tract casts or accumulation of foreign substances in urinary tract, which are involved

in formation of kidney and urinary bladder stones. The term calculus is synonymous with uroliths,

stones, or crystals, which are painful urinary disorders that start as salt/chemical crystals that

precipitate from urine. Under normal circumstances, the urine contains certain substances that

prevent crystallization. When urine fails to dissolve deposits effectively in urinary tract, such

deposits assume higher proportions which may affect the passage of urine and known as

urolithiasis 3.

Anti-urolithiatic activity from plant drugs :

The two Sidha drugs, Aerva lanata and vediuppu chunnam, tested for hyperoxaluria, calculi

induced in rats using ethylene glycol in drinking water. increased the urine volume, and reduced

calcium oxalate and other crystallizing salts 4.

The Actinidia chinesis(Plum), Vaccinium macrocarpon(Cranberry) and Ribes

nigrum(Blackcurrant) juice decreased the urinary pH, whereas the excretion of oxalic acid and the

relative supersaturation for uric acid increased. Cranbery juice acidifies urine, and found useful in

the treatment of urinary tract infection 5,6.

The effects of seven plant drugs Verbena officinalis, Lithospermum officinale, Taraxacum

officinale, Equisetum arvense, Arctostaphylos ura-ursi, Arctium lappa and Silene saxifraga dugs are

considered that it prevents and treat the kidney stone formation due to the presence of saponins 7.

The leaf extract of Coleus aromaticus has shown in reduction in deposition of urinary calculi

induced by glycolic acid in experimental rats 8.

4

Ethanolic extract of the fruits of Tribulus terrestris showed significant dose dependent protection

against uroliths of rats induced by glass bead implantation 9.

The effect of aqueous extract of Tribulus terrestris reduced oxalates in rats, where oxalates

induced by sodium glycolate. The glycolate resulted in hyperoxalurea and increased the activities of

oxalate synthesizing lever enzymes like glycolate oxidase, glycolate dehydrogenase and lactate

dehydrogenase and decreased kidney LDH activity, where the extract has reversed the activity of

above said enzymes 10.

The medication for urolithiasis to relieve the acute pain, combined tinctures of wild yam

(Dioscorea villosa), cramp bark (Viburnum opulus), kava (Piper methysticum), and Jamica dogwood

(Piscidia piscipula), Drinking the infusion of equal parts of gravel root (Eupatorium purpureum),

corn silk (Zea mays), pipissewa (Chimaphila umbellate), and kava, found to be effective in

uroilithiasis 11.

Anti-urolithiatic activity from isolated constituents:

The efficacy of the pentacyclic triterpene isolated from Crataeva nurvula, lupeol and its ester,

lupeol linoleate, against calcium oxalate urolithiasis in rats was examined. Pyridoxine deficient diet

containing glycolic acid lead to increased excretion of stone forming constituents such as calcium

oxalate and uric acid. Crystal deposition and subsequent renal tubular damage resulted in increased

excretion of the tubular enzymes alkaline phosphatase, lactate dehydrogenase. Treatment with lupeol

and lupeol linoleate reduced the extent of tubular damage with the evidence from reduced enzymuria

and minimized the excretion of stone forming constituents 12.

The pentacyclic triterpenes lupeol and its structural analogue betulin from the plant Crataeva

nurvula have been used on hyperoxaluric rats that minimized the tubular damage and reduced the

markers of crystal deposition in the kidneys. Lupeol was found to be more effective than betulin 13.

Lupeol isolated from the plant Crataeva nurvula decreased the kidney oxalate level and also

effective in counteracting the free radical toxicity by bringing about a significant decrease in

5

peroxidase levels and increase in antioxidant status 14.

Schaftoside a flavonoid isolated from Desmodum styracifolium exhibited significant anti-

urolithiatic activity by reducing the urine content like calcium, citric acid and creatinine 15.

The inhibitory effect of Desmodium styracifolium-triterpenoid (Ds-t) which was isolated from

D.styracifolium has inhibited the formation of calculi in rat kidneys by increasing the output of urine

and excretion of citrate 15.

Different extracts of Alisma orientalis on urinary oxalate stone formation on rats was induced by

ethylene glycol and ammonium chloride. In this, the ethyl acetate elution of ethyl acetate fraction of

drug significantly inhibited urinary stone formation in rat16.

Method Of Collection Of Data

The whole study is divided in the following five phases

PHASE -1:

Preparation of extracts:- petroleum ether extract, ethanolic extract, will be obtained by successive

soxhlet extraction. The marc obtained after alcoholic extraction was macerated with water to obtain

an aqueous extract.

PHASE -2:

Preliminary phytochemical investigation has been done in this phase as described by Khandelwal 29.

PHASE -3: Acute oral toxicity

Acute toxicity study for the ether, ethanolic, aqueous extract of Mimosa pudica L. will be done

according to the OECD guidelines No: 423 and, medium and high dose will be selected for

treatment.

Method:- The overnight fasted rats will be divided into 04 groups, each group consisting of 3

female animals. The EBR will be given in various doses (5, 50,300,2000) by gastric incubation

with a syringe. After administration of the extract, the animal will be observed continuously for the

first 2 hours and at 24 hrs to detect changes in behavioral responses and also for tremors,

convulsion, salivation, diarrhea, lethargy, sleep, and coma and also will be monitored up to 14 days

for the toxic symptoms and mortality.After 14 days of acute oral toxicity the survival mice will be

rehabilitated and reused in anti tumor screening.

8

PHASE -4:

Anti-urolithiatic activity: Sixty healthy adult wister rats of either sex weighing (180-250g) will be

divided into 10 groups consisting of 6 animals in each group 30.

ASSESSMENT OF ANTI-UROLITHIATIC ACTIVITY OF Mimosa pudica:Induction of urolithiasis in rats by using sodium oxalate:

Sodium oxalate induced urolithiatic model in rat will be used to assess the effect of petroleum

ether extract Mimosa pudica. The study is designed to find out the effect of extracts of Mimosa

pudica on therapeutic usage against sodium oxalate induced urolithiasis.

All rats will be housed in metabolic cages individually for entire duration of the experiment. The

urine of each rat will be collected on 7th day after 6 hrs of sodium oxlalate injection with Thymol as

a (preservative) and serum of each rat will be collected. Estimation of bio-chemical parameters viz

Urea, Uric acid, Creatinine, Sodium, Chlorides and Potassium in serum and urine will be done.

Therapeutic groups will be sacrificed on 7th day. Their right kidney will be examined for the

presence of calcium oxalate crystals and stone formation by histological techniques.

Crystal deposition is graded as grade ‘0’ – no deposition of crystals, grade ‘1’ – mild deposition

of crystals, grade ‘2’- moderate deposition of crystals and grade ‘3’- higher amount of calcium

oxalate crystals in kidney.
