Abstract
The present study was aimed to evaluate the antioxidant potential and inhibitory effect ofCannabis sativa and Morus nigra against lipid peroxidation in goat brain and liver homogenates. The formation of free radicals, highly reactive oxygen species (ROS) and reactive nitrogen species (RNS) is a normal metabolic process for cellular signaling and countering the antigens. However, they may cause serious damage if they produced at amplified tolls. In addition, metabolic disorders also serve as sources of these reactive species. Although the issue can be addressed through supplements and other phytochemicals. In this study, two plant species were evaluated for their biological potential by employing a spectrum of antioxidant assays. The antioxidant activity was performed by lipid peroxidation assay. The water extract prepared from leaves of Cannabis sativa and Morus nigra showed significant (P<0.05) inhibition as compared to control i.e., 522.6±0.06 and 659.97±0.03 µg/mL against iron-induced lipid peroxidation in goat brain homogenate while the inhibitions were 273.54±0.04 and 309.18±0.05 µg/mL against nitroprusside induced lipid peroxidation of the brain. The iron and nitroprusside induced lipid peroxidation was also significantly inhibited by leaf extracts of Cannabis sativa and Morus nigra in liver homogenates such as 230.63±0.52 and 326.91±0.01 µg/mL (iron-induced) while 300.47±0.07 and 300.47±0.07 µg/mL (nitroprusside induced), respectively. The extracts of Cannabis sativa extract showed promising activity (96.04±0.060%) against DPPH radicals while Morus nigra showed a moderate activity (34.11±0.120%). The results suggest that different accessions ofCannabis sativa and Morus nigra are a potential source of antioxidants and have a therapeutic effect against disease induced by oxidative stress and hence can be used for novel drug discovery and development.

Abstract
Objective
To evaluate the antioxidant activities and to identify the bioactive compounds in hot water extracts of Terminalia chebula fruit.
Methods
The antioxidant activities were determined by DPPH assay, lipid peroxidation assay, iron chelation and total antioxidant assay. The phenolic composition was determined by HPLC-DAD. Human Rab8b Protein was used for the validation of compounds as anti-inflammation. String analysis for protein synergism was used.
Results
The analysis of Terminalia chebula Retzius (Combretaceae) phenolics showed anti-inflammatory effect. The specific phenolic compositions were determined by high performance liquid chromatography (HPLC) and resulted in the identification of rutin, catechin, caffeic acid, gallicacid, ellagic acid, epicatechin, and quercetin as antioxidant compounds. Human Rab8b protein is selected for protein docking and all compounds except rutin showed good results. ADMET properties were checked by using AdmetSar and all seven compounds showed validation for AMET properties. The synergisms of compounds were analyzed by STRING analysis and our ligands shows strong binding with human Rab8b proteins. The aqueous extract was capable of inhibiting the lipid peroxidation in egg yolk phospholipid homogenate. The extract scavenged the 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) (IC50,71.5 ± 2.1 μg/ml). The extract displayed the high metal chelation activities and reducing abilities on the phosphomolybdenum assay.
Conclusions
It is concluded that extracts of T. chebula have good antioxidant and anti-inflammation activities and are rich in phenolics.

Abstract
Zanthoxylum alatum Roxb. (Rutaceae) is a medicinal plant, which abundantly grows in the hilly areas of Pakistan. In the present study, the hepatoprotective activity of the Z. alatum whole fruit was evaluated. The hepatoprotective effect of the aqueous extracts was studied on mice liver damage using a single dose of paracetamol (640 mg/kg) orally by monitoring biochemical parameters. Pre-treatment of mice with Z. alatum (100 mg/kg) aqueous extract orally for four days prevented the paracetamol induced rise in serum transaminases (ALT and AST), restored the altered levels of antioxidant enzyme (catalase), thiobarbituric acid reactive substances (TBARS), non-protein thiol and ascorbic acid to near normal levels. The major phenolic acids, some flavonoid aglycone and glycosides were identified in fruit by high performance liquid chromatography. Ellagic acid (24.57±0.01mg/g), chlorogenic acid (10.65±0.01mg/g), gallic acid (9.15±0.02mg/g), chrysin (16.81±0.03), quercetin (16.81±0.03mg/g) and epicatechin (10.93±0.01) were prédominant in infusion of Z. alatum. The result substianted the hepatoprotective activity of Z. alatum which may be associated with its potential use in liver disease.

Abstract
BACKGROUND The present study compares the protective properties of aqueous extracts of six medicinal plants, Phyllanthus emblica, Terminalia chebula (black and yellow), Terminalia arjuna, Balsamodendron Mukul and Alium sativum against lipid per-oxidation in mice brain. METHODS The antioxidant activities were analyzed by lipid per-oxidation assay, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical assay, total antioxidant activity and metal chelation. RESULTS The extracts (fruits and bark) showed inhibition against thiobarbituric acid reactive species (TBARS) induced by pro-oxidant (10 µM FeSO4) in mice brain. Moreover, the free radical scavenging activities of the extracts was evaluated by the scavenging of DPPH radical (IC₅₀, 23.23 ± 1.2 µg/ml (Phyllanthus emblica), 20.24 ± 0.9 µg/ml (Terminalia chebula yellow) and 17.33 ± 1.1 µg/ml (Terminalia chebula black), 19.44 ± 0.45 µg/ml (Terminalia arjuna), 56.59 ± 2.1 µg/ml (Balsamodendron Mukul) and < 200 µg/ml (Alium sativum). CONCLUSION The higher antioxidant and inhibitory effect of Terminalia chebula black in this study could be attributed to its significantly higher phenolic content, Fe(II) chelating ability, reducing ability and free radical scavenging activity. Therefore oxidative stress in brain could be potentially prevented by the intake of these plants.

Abstract
β-Seleno amines were screened for in vitro antioxidant activity. The compounds (C1-C4) were tested against lipid peroxidation induced by iron and sodium nitroprusside in rat brain and liver homogenates. The compounds showed inhibition against thiobarbituric acid reactive species (TBARS) induced by different pro-oxidants (10μM FeSO(4) and 5μM sodium nitroprusside (SNP) in rat brain and liver homogenates. The compounds exhibited strong antioxidant activity in 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and phosphomolybdenum assays. The IC(50) values revealed that the β-seleno amines in which the amino group was protected with protecting groups tert-butyloxycarbonyl (Boc) and Tosyl (Ts) groups showed better antioxidant profiles compared to the free monoselenides. The total antioxidant activity of C1, C2, C3 and C4 were found to be 85.2±11.5, 114±7.9, 138±8.5, 125.81±5.2μM/ml of ascorbic acid respectively. Therefore, these compounds may be used as synthetic antioxidants.

Abstract
AIM OF THE STUDY Solanum fastigiatum is a medicinal plant widely distributed in the south of Brazil and has been used mainly to treat hepatitis, spleen disorders, uterine tumors, irritable bowel syndrome and chronic gastritis. The present research was aimed to evaluate the potential antioxidant and hepatoprotective activity of aqueous extracts of leaves using in vitro and in vivo models to validate the folkloric use of the plant. MATERIALS AND METHODS Antioxidant activity was evaluated by different assays, including thiobarbituric acid reactive species (TBARS), total antioxidant, 2,2-diphenlyl-1-picrylhydrazyl (DPPH) radical and metal ion-chelating activities. The hepatoprotective activity of the aqueous extracts was studied on mice liver damage induced by paracetamol (250mg/kg) by monitoring biochemical parameters. RESULTS The extract showed inhibition against TBARS, induced by 10microM FeSO(4) and 5microM sodium nitroprusside in rat liver, brain and phospholipid homogenates from egg yolk. The plant exhibited strong antioxidant activity in the DPPH (IC(50), 68.96+/-1.25microg/ml) assay. The aqueous extract also showed significant hepatoprotective activity that was evident by enzymatic examination and brought back the altered levels of TBARS, non-protein thiol and ascorbic acid to near the normal levels in a dose dependent manner. Acute toxicity studies revealed that the LD(50) value of the extract is more than the dose 4g/kg body weight of mice. CONCLUSIONS The results indicate that this plant possesses potential antioxidant and hepatoprotective properties and has therapeutic potential for the treatment of liver diseases.

Abstract
Sea buckthorn (Hippophae rhamnoides ssp. turkestanica) is a very important medicinal plant in northern areas of Pakistan. The fruit of sea buckthorn is rich in nutrients and medicinal compounds such as vitamins, carotene, flavonoids, essential oil, carbohydrates, organic acids, amino acids, and minerals. In order to compare various populations of sea buckthorn for chemical composition, eight populations from different areas of northern Pakistan were compared using fruit characteristics. Phytochemical analysis of berries showed vitamin C (250-333 mg/100 g), seed oil (7.69-13.7%), oil in softer pulp (19.2-29.1%), phytosterol content of seed oil (3.3-5.5%), and anthocyanin (0.5-25 mg/L), while the mineral element composition analysis revealed high contents of potassium (140-360 ppm), sodium (20-80 ppm), calcium (70-98 ppm), magnesium (150-240 ppm), iron (40-150 ppm), and phosphorus (110-133 ppm). This study established sea buckthorn berries as a good source of biochemical and mineral elements. The high variation between different populations shows the potential of selecting and breeding of the raw material for various defined purposes.

Abstract
BACKGROUND Microbial keratitis occurs infrequently in childhood. The leading ocular predisposing factors are trauma and preexisting corneal disease. Many of the age-related risk factors in adults play a minor role in children. METHODS The authors retrospectively studied 51 eyes with ulcerative keratitis in 50 children younger than 16 years of age. This includes all patients treated at Bascom Palmer Eye Institute during an 11 1/2-year period from January 1, 1980, to June 30, 1991. The criterion for inclusion in the study was a discharge diagnosis of microbial (nonviral) keratitis. RESULTS The principal risk factors identified in this study were trauma (44%), prior corneal surgery (24%), systemic illness (14%), and contact lens wear (12%). Systemic illness or an immunocompromised state existed in 7 (47%) of the 15 children younger than 3 years of age. There was a large male preponderance (68%). Forty-four (86.3%) of the 51 eyes were culture-positive; six (11.7%) were polymicrobial. Five of seven culture-negative patients had received prior topical antibiotic therapy. Pseudomonas aeruginosa (34%), Staphylococcus aureus (20%), and fungi (18%) were the most common organisms isolated. Seven (14%) eyes required surgery. CONCLUSION This study presents important differentiating factors between adult and childhood nonviral microbial keratitis. Identification of principal risk factors in children may aid in early recognition and treatment of microbial keratitis.
