Evaluation of the in vivo antihypertensive effect and antioxidant activity of HL-7 and HL-10 peptide in mice.
Article in Molecular biology reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe tendency to use bioactive peptides has increased in recent decades, and research would be essential for recognizing the therapeutic effects of peptides present in animals or food resource. In this study, the in vivo antioxidant and antihypertensive properties of peptides HL-7 with the sequence of YLYELR and HL-10 with the sequence of AFPYYGHHLG were identified from scorpion venom of H. lepturus were evaluated. METHODS AND
resultsTo study the in vivo effects of peptides, D-galactose-induced and DOCA salt-induced mice models were used. The results of the antioxidant assay for both peptides showed that the activity of serum and liver catalase (CAT), as well as superoxide dismutase (SOD) enzymes, was significantly decreased in the D-galactose-induced group (NC), while MDA levels were increased in serum and the liver tissue samples (p < 0.01). Compared with the D-galactose-induced mice, the peptide treated mice group had a higher activity of antioxidant enzymes namely CAT and SOD, as well as a lower lipid peroxidation level. Also, the results of antihypertensive activity for both peptides showed that systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the mice treated with the HL-7 and HL-10 peptides were significantly reduced in a dose-dependent manner (p < 0.01). The administration of the HL-7 peptide at doses of 2 mg/kg BW (LP1), 5 mg/kg BW (-IP1) and 15 mg/kg BW (HP1) significantly diminished the mean arterial blood pressure (MAP) by 11 mmHg, 31 mmHg and 40.47 mmHg, respectively. Accordingly, treatment of mice with the HL-10 peptide at doses of 2 mg/kg BW (LP2), 5 mg/kg BW (IP2) and 15 mg/kg BW (HP2) considerably lowered the MAP by 8 mmHg, 18.3 mmHg and 21.93 mmHg, respectively.
conclusionOur findings suggest that both the HL-7 and HL-10 peptides could be potentially utilized as antihypertensive and antioxidant components.
