Dose calculation
1) Preparation of 1% v/v Tween 80 in saline: (for 150 mL)
100 mL saline contains 1 mL Tween 80
150 mL saline contains 1×150
100 Tween 80
= 1.5 mL Tween 80
So, 1.5 mL Tween 80 takes in a volumetric flask and volume adjust to 150 mL with saline.
2) Preparation of positive control:
Dose: Diazepam 1mg/kg average body weight
Let average body weight = 25 g = (25 × 1000) mg =25000 mg
So, for (1000 × 1000) mg body weight requires 1 mg
25000 mg body mg body weight requires 1×25000
1000×1000 mg
= 0.025 mg
0.5 mL contains 0.025 mg Diazepam
10 mL contains 0.025×10
0.5 mg Diazepam
= 0.5 mg Diazepam = 0.0005 g Diazepam
So, 0.0005 g Diazepam takes in a test tube and volume adjust to 10 mL with saline.
3) Preparation of plant extract preparation:
A) Dose: 400 mg/ kg average body weight
Let average body weight = 25 g = (25 × 1000) mg =25000 mg
So, for (1000 × 1000) mg body weight requires 400 mg
25000 mg body mg body weight requires 400×250001000×1000
mg
= 10 mg
0.5 mL contains 10 mg plant extract
5 mL contains 5×10
0.5 mg plant extract
= 100 mg plant extract = 0.1 g plant extract
So, 0.1 g plant extract takes in a test tube and volume adjust to 5 mL with saline.
B) Dose: 200 mg/ kg average body weight
Let average body weight = 25 g = (25 × 1000) mg =25000 mg
So, for (1000 × 1000) mg body weight requires 200 mg
25000 mg body mg body weight requires 200×250001000×1000
mg
= 5 mg
0.5 mL contains 5 mg plant extract
5 mL contains 5×50.5
mg plant extract
= 50 mg plant extract = 0.05 g plant extract
So, 0.05 g plant extract takes in a test tube and volume adjust to 5 mL with saline.
4) Calculation for acetic acid: (0.1 mL/ 10g)
Let average body weight = 25 g
So, for 10 g body weight requires 0.1 mL acetic acid
25 g body mg body weight requires 25× .01
10 mL acetic acid
= 0.25 mL acetic acid
Serial dilution
0.004 g plant extract dissolves in 200 µl of DMSO

(Concentration 100 µg/ml) (Concentration 50 µg/ml)
Volume adjust to 5 ml by saline 2.5 ml solution + 2.5 ml saline + shrimp
(Concentration 50 µg/ml) (Concentration 25 µg/ml)
Volume adjust to 5 ml by saline 2.5 ml solution + 2.5 ml saline + shrimp
(Concentration 25 µg/ml) (Concentration 12.5 µg/ml)
(Up to 0.7813 5 µg/ml)
