\begin{abstract}
The present study is carried out to evaluate anti-inflammatory and anti-arthritic potential of \textit{Justicia gendarussa}. Leaves and stem extracted with ethanol and chloroform. These extract is tested against in-vitro (HRBC membrane stabilization method and Inhibition of protein denaturation method) and in-vivo (Carrageenan induced paw edema model) anti-inflammatory models. To assess the anti-arthritic activity, FCA induced arthritis model is used. Assessment of arthritis is done by paw volume, joint diameter, body weight, biochemical parameters, hematological parameters (Hb, RBC, WBC, ESR). The effect of in-vitro anti-inflammatory model depends on concentration. Both test extract and standard Diclofenac sodium has been shown concentration dependent effect. The maximum anti-inflammatory effect of the test extract achieved at 2000\ensuremath{\mu }g/ml. The test (JGLE, JGLC, JGSE) has been shown inhibition of paw edema induced by carrageenan at 50mg/kg body weight. The extract JGLE, JGLC, JGSE at 50mg/kg body weight and 100mg/kg body weight orally showed the significant (P\textless\ 0.05) and dose dependent inhibitory effect against FCA induced arthritis model. Diclofenac sodium 20mg/kg body weight orally is used as a standard. JGLE exhibit more significant and most promising anti-arthritic and anti-inflammatory effect than other extracts these effects support the traditional role of \textit{J. gendarussa} in arthritis and other inflammatory condition.

\section{ Introduction}
Inflammation is a response of immune system that protects the host against the foreign substance. The major four vital signs of acute inflammation are as follows, Calor (heat), Rubor (redness), tumor (swelling) and dolor (pain), leading to Functiolaesa loss (or impairment) of function \unskip~\citep{996260:21345195}. Inflammatory process which is successful or controlled in manner is needed that leads to the removal of dangerous stimuli and also help in the restoration of normal physiology (cellular or tissue physiology) \unskip~\citep{996260:21345228}.

\textbf{Rheumatoid Arthritis}

Rheumatoid arthritis (RA) is an autoimmune disorder which shows the chronic inflammatory responses and also causes the symmetrical polyarthritis primarily in the synovial joints. Some triggering events initiate the inflammatory pathway where the immune cells play the greater role and the some inflammatory mediators like cytokines, some enzymes proteinase play a crucial role in the joint destruction \unskip~\citep{996260:21345219}. The major targets of rheumatoid arthritis is synovial joints which leads to the destruction of the synovial joints and their membrane causes joint disability, arthralgia, swelling, redness and also limit the joint movement \unskip~\citep{996260:21345215}. Arthritis is a common term with a joint paint as a primary feature which includes osteoarthritis (OA), rheumatoid arthritis (RA) and psoriatic arthritis \unskip~\citep{996260:21345227}. In traditional medicine system the plant aerial part of \textit{Justicia gendarussa} (f. Acanthaceae) is very well known for its various therapeutic activities \unskip~\citep{996260:21345217}. Leaves contain, alkaloids, flavonoids, saponin, steroids, O-distributed aromatic amine i.e., 2-(2'-amino-benzylamino) benzyl alcohol and their respective O-methyl ethers, stigmasterol, lupeol, 16-hydroxylupeol, 28\ensuremath{\beta }-sitosterol \unskip~\citep{996260:21345214}. The plant shows the various therapeutic activity like, anti-arthritic \unskip~\citep{996260:21345209,996260:21345205}, anti-inflammatory \unskip~\citep{996260:21345211}, anti-bacterial \unskip~\citep{996260:21345213}, dyspepsia \unskip~\citep{996260:21345222}, cytotoxic \unskip~\citep{996260:21345196}, anti-angiogenic \unskip~\citep{996260:21345197}, anti-fungal \unskip~\citep{996260:21345207}, Cough \unskip~\citep{996260:21345229}, hepatoprotective \unskip~\citep{996260:21345204,996260:21345200}, anti-anxiety activity \unskip~\citep{996260:21345201}, anti-depressant effect \unskip~\citep{996260:21345210}, sedative and hypnotic activity \unskip~\citep{996260:21345201}, anti-diabetic \unskip~\citep{996260:21345220}.
    
\section{Materials and Methods}
The leaf and stem part of the plant \textit{Justicia gendarussa} purchased from the market of Delhi, India. The part of the plant is authenticated from the NISCAIR (National Institute of Science Communication \& Information Resources) Delhi, India with authentication No. (Ref. No.- NISCAIR/Consult/2019/3539-40). 

\textbf{Preparation of Extract}

Fresh and dried leaf and stem part of \textit{Justicia gendarussa} were coarsely power by mechanically. Extraction of the leaves and stem part is done by using the solvent ethanol (95\%) and chloroform (95\%) by soxhlet apparatus. Distillation process is used to concentrate the extract. The extract evaporates to dryness. Extract (JGLC, JGLE and JGSE) was kept in vacuum desiccators until use \unskip~\citep{996260:21345205}.

\textbf{HRBC (Human Red Blood Cell) membrane stabilization method}

\textbf{Reagents Preparation}

For the preparation of the Alsevers solution dissolve 2gm dextrose, 0.8gm sodium citrate, 0.05gm citric acid and 0.42gm sodium chloride dissolve in distilled water and make-up the volume upto 100ml. Preparation of the Hypotonic saline is done by dissolving the 0.36gm of sodium chloride in 100ml distilled water. To prepare the Isotonic solution dissolve the 0.85gm of Sodium chloride in 100ml distilled water. For the preparation of the phosphate buffer (pH 7.4) take 2.38gm disodium hydrogen phosphate, 0.19gm of potassium dihydrogen phosphate and 8gm of sodium chloride and dissolve in 100ml distilled water\unskip~\citep{996260:21345198}. Human red blood cell (HRBC) is used to determine the in-vitro anti-inflammatory activity of the test compound (plant extract)\unskip~\citep{996260:21345221}. Blood collected from the healthy human volunteer who has been not taken any sort of NSAIDs (Non steroidal anti-inflammatory drugs) 2 week prior from the experiment. The freshly collected blood is added in the equal volume of Alsever solution. The whole mixture (Blood and Alsever solution) is centrifuged at the 3000rpm (10min). The separated packed cells obtained after the centrifuge were washed with three time freshly prepared isosaline solution (.85\%, pH 7.2). The total volume of the blood is measured and make the 10\% v/v suspension with isosaline solution\unskip~\citep{996260:21345226}. The total reaction mixture contain the 1mL of phosphate buffer, 2mL of hyposaline [0.36\%], 0.5mL of HRBC suspension and 0.5mL of different concentration of plant extract (100, 200, 400, 800 and 1600\ensuremath{\mu}g/ml) and reference compound Diclofenac sodium (50, 100, 200, 400, 800 and 1600 \ensuremath{\mu}g/ml)\unskip~\citep{996260:21345221}. The whole reaction mixture was incubated at the 37\ensuremath{^{0}}C for the period of 30min and after the completion of the incubation the mixture is centrifuged at the 3000rpm for the time period of 20min. The supernatant is decanted and the total Hb content of the middle layer of the suspension is estimated spectophotometrically at 560nm \unskip~\citep{996260:21345216}.

The total \% of hemolysis of HRBC membrane stabilization can be calculated by using the formula ,

\% Hemolysis = 
\begin{eqnarray*}\style{font-size:9px}{\frac{\left(Optical\;density\;of\;Test\;sample\right)}{Optical\;density\;of\;control}\times100} \end{eqnarray*}
The total \% of HRBC membrane stabilization calculated by,

\% Protection = 
\begin{eqnarray*}\style{font-size:9px}{100-\left[\left(\frac{Optical\;density\;of\;test\;sample}{Optical\;density\;of\;control}\right)\times100\right]} \end{eqnarray*}
\textbf{Evaluation of anti-inflammatory activity by protein denaturation Inhibition method}

The total reaction mixture (50mL) contains the 2mL of fresh egg albumin (from hen's fresh egg), 28mL of phosphate buffer saline (PBS, pH 6.4) and add 20mL of varying concentration of JGLC, JGLE and JGSE to be the final concentration to become 10, 50, 100, 200, 400, 800, 1000, and 2000 \ensuremath{\mu }g/mL. Same volume of double distilled water has been taken as control. The whole reaction mixture was incubated by using the BOD incubator (37\ensuremath{\pm}2) \ensuremath{^\circ}C for 15 min and heated at 70 \ensuremath{^\circ}C for 5 min on water bath, kept aside for cooling and measure the absorbance at 660nm under UV 1800 spectrophotometer. Reference diclofenac sodium at the concentration of 10, 50, 100, 200, 400, 800, 1000, 2000 \ensuremath{\mu}g/mL was used and take a similar treatment to determine the absorbance and the viscosity were also determined for both the sample (test and standard) through the Ostwald viscometer\unskip~\citep{996260:21345221}.

The total \% inhibition of the protein denaturation was determined by,

\% Inhibition = 
\begin{eqnarray*}\style{font-size:9px}{100\times\left(\frac{Vt}{Vc\;}-1\right)} \end{eqnarray*}
Vt = Total absorbance of test sample

 Vc = Total absorbance of control sample 

\textbf{Experimental Animals}

Wistar rat body weight 200-250gm taken from the animal house facility, KIET School of Pharmacy, Ghaziabad. The animals are stored in the cage which is made up of polypropylene under standard laboratory condition (12hr. light and 12hr. dark) and had a free access for food and water. The temperature of animal house maintained at 25 \ensuremath{\pm} 2\ensuremath{^{o}}C. The approval of the protocol to be approved by the Institutional Animal Ethical Committee (IAEC) of KIET School of Pharmacy (IAEC/KSOP/E/10/06), Ghaziabad.

\textbf{Carrageenan Induced Paw Edema Model}

Male Wistar rats having body weight 200-300gm is used for the assessment of hind paw edema. The procedure of \unskip~\cite{996260:21345222}  is employed in this model. For the induction of edema in the right hind paw 0.1ml of 1\% carrageenan in 0.9\% saline aponeurosis injection is injected\unskip~\citep{996260:21345222}. Injection is inserted in right hind paw after 1hr. of oral administration of plant extract which is extracted in various solvent. Extract of plant \textit{Justicia gendarussa} evaluated for its anti-inflammatory in the solvent ethanol and chloroform (JGLE, JGLC, and JGSE) at the concentration of 50mg/kg body weight orally \unskip~\citep{996260:21345206}. Each groups having 6 animals in the groups (n=6). Reference compound diclofenac sodium at the concentration of 20mg/kg/b.w is used by oral route before 1 h to carrageenan induction. The volume of paw edema is measured at time interval of 1, 3, and 5 h by using the dial Vernier calliper and mercury plethymometer \unskip~\citep{996260:21345211}.

Group I~(Normal control) received 0.9\% Normal control, Group II (Inflammation control) received Carrageenan + 0.9\% Normal saline, Group III (Standard control) received Carrageenan + Diclofenac sodium (20mg/kg), Group IV (JGLE) received JGSE extract (50mg/kg body weight orally), Group V (JGLC) received JGSE extract (50mg/kg body weight orally), Group VI (JGSE) received JGSE extract (50mg/kg body weight orally). 

The calculation of the total swelling inhibition rate and the total edema inhibition rate to be done by,

\% edema inhibition = 
\begin{eqnarray*}\style{font-size:9px}{\frac{\left(Vc\;-\;Vt\right)}{Vc}\times100} \end{eqnarray*}

\textbf{FCA (Freund's Complete Adjuvants) Induced Arthritis Model}

FCA (Freund's Complete Adjuvants) Induced Arthritis Model is used to performed anti-arthritic effect of test drug by using the wistar rats. Animals divided into 9 groups and every group having the 6 animals in each group. Arthritis induction is achieved by the use of Full Adjuvants (FCA) from the Freund. In the FCA induced arthritis model that has 10 mg of dry heat-killed sterile paraffin oil Mycobacterium butyricum / ml is injected into the plantar surface of the animal's left hindfoot. Treatment of the animals starts from 20\ensuremath{^{th}} day of arthritis and the treatment is continued for 20\ensuremath{^{th}} days. During this 20\ensuremath{^{th}} day of treatment body weight of animal and the paw volume to be takes at the regular interval. The blood is obtained by retro-orbital puncture and various hematological parameters such as, Hb, RBC, WBC, ESR to be performed at the end of the test [9]. Anti-arthritic activity assessment of extract (JGLE, JGLC, JGSE) is done at 50mg/kg body weight orally and 1000mg/kg body weight orally and standard Diclofenac sodium (20mg/kg/b.w) is used orally \unskip~\citep{996260:21345205,996260:21345211}.

Group I~(Normal control) receive Normal saline, Group II (Arthritic control) FCA 0.1ml + Normal saline, Group III (Standard control) FCA 0,1ml + Diclofenac sodium 20mg/kg/b.w., Group IV (JGLEH) JGLE extract 100mg/kg body weight orally, Group V (JGLEL) JGLE extract 50mg/kg body weight orally, Group VI (JGLCH) JGLC extract 100mg/kg body weight orally, Group VII (JGLCL) JGLC extract 50mg/kg body weight orally, Group VIII (JGSEH) JGSE extract 100mg/kg body weight orally, Group IX (JGSEL) JGSE extract 50mg/kg body weight orally.

\section{Conclusions}
The current work investigated the anti-inflammatory work of various extract \textit{Justicia gendarussa} by using the in-vitro and in-vivo models and the extract JGLE, JGLC, and JGSE is used to evaluate for their anti-inflammatory activity. In the anti-inflammatory (in-vitro) study there are 2 models (Inhibition of protein denaturation and Human red blood cell membrane stabilization method) are used and the effect of these extracts for these in vitro-study were measured or evaluated at concentration (50, 100, 200, 400, 800, 1000, 2000 \ensuremath{\mu}g/ml) and (50, 100, 200 400, 800, 1600 \ensuremath{\mu}g/ml) respectively. Effect of the test extract increases with the concentration and the extract JGLE to be found most effective at the concentration of 2000\ensuremath{\mu}g/ml in both the models and the results of the extracts was compare with the reference drug, Diclofenac sodium, at the same concentration. Carrageenan paw edema model is used as in-vivo method for the evaluation the anti-inflammatory potential of the test extract JGLE, JGLC, and JGSE which is obtained from the aerial part of \textit{Justicia gendarussa} plant. The plant extract (JGLE, JGLC and JGSE) concentration 50mg/kg/b.w.p.o is used and the result is compare with the reference compound Diclofenac sodium at 20mg/kg/b.w.p.o. The extract JGLE has been shown more paw edema inhibition than the other extracts. The anti-arthritis ability of the plant \textit{Justicia gendarussa} extract as JGLE, JGLC and JGSE was evaluated using the arthritis model induced by FCA in Wistar rats. To evaluate the anti-arthritic effect of test extract various parameters like, Hematological parameters (Hb, WBC, RBC, ESR), biochemical parameters, body weight, paw volume, and paw thickness (joint diameter) are used. The concentration at which the test extract exert its anti-arthritic potential is 50mg/kg/b.w.p.o and 100mg/kg/b.w.p.o is used and the whole test extract data is compared with the reference drug Diclofenac sodium at 20mg/kg/b.w.p.o is used. The ethanolic extract of the \textit{Justicia gendarussa} shows the much better improvement in the parameters than other extract. Saponins (Apigenin) are well known for their anti-inflammatory activity, which effectively reduce oxidative stress and express multiple factors that potentiate inflammation and also play a crucial role in reducing these factors, they are responsible for the inflammation and other disease related complications. A flavonoid (vitexin) is also present which is potent anti-inflammatory agents vitexin successfully encounters the inflammatory activity. They inhibit 5-lipoxygenase pathway, which increase the synthesis of inflammatory mediators along with the COX-2 pathway. This mechanism strongly supports the carrageenan induced inflammation. By successfully inhibiting the pathway of 5-lipoxygenase (5-LOX) and cyclooxygenase-2 (COX-2), extracts is successfully inhibited the synthesis of various inflammatory mediators like, prostaglandins (PGs), Interleukins (ILs), tumor necrosis factors (TNF-\ensuremath{\alpha }), leukotrines (LTA\ensuremath{_{4}}, LTB\ensuremath{_{4}}, LTC\ensuremath{_{4}}, LTD\ensuremath{_{4}}, LTE\ensuremath{_{4}}), TXA\ensuremath{_{2}} etc. Increase synthesis of these inflammatory mediators contributes process of inflammation and also makes the disease more complicated like arthritis.
