The seahorse (Hippocampus comes L.) extract ameliorates sperm qualities, testosterone level, and serum biochemistry in rats induced by depo medroxyprogesterone acetate.

Objective: The percentage of infertility cases in this world is about 50%. Seahorses (Hippocampus spp.) are widely used in traditional medicine. Several studies suggest that seahorses have ethnopharmacological characteristics, such as fertility, antioxidants, and antifatigue. The purpose of this study was to determine whether seahorse extract (SE) (Hippocampus comes L.) has an effect on fertility and serum biochemistry in rats induced by depo medroxyprogesterone acetate (DMPA). Materials and Methods: All animals were induced with 1.25 mg/kg BW of DMPA. Animals were grouped into five groups: namely aquadest, 1% CMC, and SE doses of 150, 225, and 300 mg/kg BW. The rats were gavage every morning from week 7 until 18. At the end of our study, semen from the vas deferens and blood from the heart were analyzed. We analyzed with a one-way analysis of variance and Bonferroni's post hoc tests (α 95%). Results: The concentration of spermatozoa had a significant difference in dose of 150 mg/kg BW compared to other groups (p = 0.04). In contrast, the motility (p = 0.012) and viability of spermatozoa (p = 0.007) were highly significant differences (p < 0.05 and p < 0.01) at 300 mg/kg BW. Testosterone levels were not significantly (p = 0.162; p > 0.05), but tended to increase at 300 mg/kg BW (11.01%). Nevertheless, serum biochemistry was insignificant (p > 0.05) in all groups. Conclusion: SE (Hippocampus comes L.) ameliorates fertility and serum biochemistry in rats induced by DMPA.

Changes in Gut Microbiota and Systemic Inflammation after Synbiotic Supplementation in Patients with Systemic Lupus Erythematosus: A Randomized, Double-Blind, Placebo-Controlled Trial.

Gut dysbiosis has a role in the pathogenesis of lupus. Synbiotic supplementation may restore the balance of gut microbiota. This study investigated whether synbiotics could improve gut microbiota and systemic inflammation in lupus patients. This randomized, double-blind, placebo-controlled trial was conducted in adult systemic lupus erythematosus (SLE) patients. Subjects were randomized to receive either synbiotics or a placebo. Fecal microbiota, hs-CRP, IL-6, and IL-17 were measured at baseline and after 60 days. Patients who fulfilled the inclusion criteria were randomized into synbiotic (n = 23) and placebo groups (n = 23). In the synbiotic group, hs-CRP was not significantly increased (1.8 [0.9; 4.85] vs. 2.1 [0.9; 4.25] mg/L; pre vs. post; p = 0.23), whereas in the placebo group hs-CRP was increased significantly (1.75 [0.4; 4.45] vs. 3.75 [0.58; 7.05] mg/L; pre vs. post; p = 0.005). In the synbiotic group, IL-6 decreased significantly (8.76 [6.62; 11.39] vs. 6.59 [4.96; 8.01]; pre vs. post; p = 0.02), while there was no significant change in IL-17 level. In the placebo group, there was no significant change in IL-6 and IL-17. Synbiotic supplementation increased the Firmicutes:Bacteroidetes ratio (0.05 ± 0.60 vs. -0.08 ± 0.63, synbiotic vs. placebo p = 0.48) and butyrate metabolism (p = 0.037) and decreased amino sugar and nucleotide sugar metabolism (p = 0.040). There was improvement in the SLE disease activity index 2K (SLEDAI-2K) score in the synbiotic group (14 [9; 16] vs. 8 [2; 12]; pre vs. post; p < 0.001), while no change in the placebo group (9 [8; 18.25] vs. 9 [5.5; 15]; pre vs. post; p = 0.31). Synbiotic supplementation could reduce systemic inflammation and SLE disease activity and alter the composition and functions of gut microbiota.

Characterization of seahorse (Hippocampus comes L.) extracts originating from culture and nature in Pesawaran, Lampung, Indonesia.

Objective: Indonesia is an archipelagic country with a mega biodiversity, among others, in the marine area. Seahorses (Hippocampus spp.) are a marine fish known to have biocompounds used in traditional medicine "Jamu," such as Hippocampus comes L. (HCL). The present study aims to analyze and compare the chemical contents of cultured seahorse (CS) and natural seahorse (NS) extracts. Materials and Methods: The CS and NS were identified morphometrically. After freeze-drying, the seahorses were ground into powder with a grinder. The seahorse powder was extracted with ethanol and a water solvent. The extract contained biocompounds, proximate, amino acids, and steroids with high-performance liquid chromatography. Results: The study found unique characteristics of HCL. The highest yield was obtained in NS using a water solvent (18.6%). The biocompounds in seahorses consist of alkaloids and triterpenoids. The highest proximate of water content (11.03%) and ash content (42.50%) was found in NS. In addition, other compounds were also detected in CS, such as fat (7.48%) and protein (47.67%). Both of HCL's different sources had all essential and nonessential amino acids in which the highest concentration were in NS, i.e., L-arginine (56,537.22 mg/kg), L-lysine (17,794.17), glycine (113,649.80 mg/kg), L-proline (47,056.15), and L-alanine (43,451.81). The analysis of the steroid compound of the extract suggested the presence of steroid glycosides. Conclusion: The highest yield of the seahorse extract with a water solvent is about 18.6% and protein content of 47.67% in CS. The crude extract has alkaloids, triterpenoids, and glycine (113,649.80 mg/kg) in NS with water, suggesting the presence of steroid glycosides.
