Protective Effect of Leaf Ethanolic Extract Etlingera hemisphaerica Blume Against Mercuric Chloride Toxicity in Blood of Mice

Etlingera hemisphaerica Alters One-Dimensional Profile of Serum Proteins Due to Mercury Chloride in Rats (Rattus norvegicus)

<b>Background and Objective:</b> Several previous studies have shown that leaf ethanolic extract of <i>Etlingera hemisphaerica</i> (LE3H) has the potential to reduce the toxicity and teratogenicity effects of mercury. This study aimed to describe the effects of LE3H on the protein profile of <i>Rattus norvegicus</i> serum due to treatment with HgCl₂. <b>Materials and Methods:</b> Four groups of male rats, K1 was injected intraperitoneally (IP) HgCl₂ (5 mg kg¹ b.wt.), K2 was injected IP HgCl₂ (5 mg kg¹ b.wt.) and after 24 hrs it was gavage LE3H (0.27 mg g¹ b.wt.) every day for seven days, K3 was injected IP HgCl₂ (5 mg kg¹ b.wt.), after 24 hrs was gavage LE3H (0.55 mg g¹ b.wt.) every day for seven days. The K0 as control, received double-distilled water. On the ninth day, the experimental animals were killed via CD and blood was drawn from the heart to obtain serum. Serum samples were measured for protein content using the Lowry and serum was separated using the One-Dimensional Sodium dodecyl Sulfate-Polyacrylamide gel Electrophoresis (1D SDS-PAGE) technique. <b>Results:</b> The electropherograms showed four bands, 264.77, 219.53, 98.57 and 37.29 kDa, whose intensity significantly increased due to HgCl₂ treatment and then decreased to close to the control condition with LE3H administration. The results also revealed four bands, 31.95, 28, 06, 26, 29 and 15.09 kDa, whose intensity decreased significantly due to HgCl₂ treatment and then increased to close to the control condition by LE3H administration. <b>Conclusion:</b> The LE3H change profile of the eight blood serum protein bands due to HgCl₂ approximates the control condition in <i>R. norvegicus</i>.

Potential of Leave and Fruit Ethanolic Extract of Etlingera hemisphaerica as Antihyperuricemic in Mice (Mus musculus)

&lt;b&gt;Background and Objective:&lt;/b&gt; Hyperuricemia is a disease triggered by disorders of uric acid metabolism. Therefore, this study evaluated the potential of leaves ethanolic extract of &lt;i&gt;Etlingera hemisphaerica&lt;/i&gt; (LE3H) and fruits ethanolic extract &lt;i&gt;E. hemisphaerica&lt;/i&gt; (FE3H) to restore hyperuricemia in mice. &lt;b&gt;Materials and Methods:&lt;/b&gt; Six groups (A0, A1, A2, A3, A4 and A5) each consisted of four male mice. Hyperuricemia in mice was induced by giving 0.3 mL of fresh chicken liver juice (FCLJ) for seven days (A1, A2, A3, A4 and A5). The condition of hyperuricemia in A1 is not neutralized. Meanwhile, hyperuricemia conditions in A2, A3, A4 and A5 were neutralized for seven days by giving 0.01 mg g&lt;sup&gt;&lt;/sup&gt;&lt;sup&gt;1&lt;/sup&gt; body weight (BW) allopurinol, 0.13, 0.26 and 0.36 mg g&lt;sup&gt;&lt;/sup&gt;&lt;sup&gt;1&lt;/sup&gt; BW LE3H. The control group (A0) only received double-distilled water in the same way. Blood uric acid levels were measured with the GCU Meter Device before and after the induction of hyperuricemia and after efforts to neutralize the hyperuricemia condition. Six groups (B0, B1, B2, B3, B4, B5) each consisting of four male mice were also provided to test the potential of FE3H. The recovery potential FE3H against hyperuricemia was tested separately in the same way as was done for LE3H. &lt;b&gt;Results:&lt;/b&gt; Giving FCLJ significantly increased (140.00-187.00%) uric acid compared to the control, so hyperuricemia was achieved. Doses of 0.13, 0.26 and 0.36 mg g&lt;sup&gt;&lt;/sup&gt;&lt;sup&gt;1&lt;/sup&gt; BW LE3H significantly recovered hyperuricemia as much as 54.09, 56.14 and 60.88%, respectively. Meanwhile, doses of 0.13, 0.26 and 0.36 mg g&lt;sup&gt;&lt;/sup&gt;&lt;sup&gt;1&lt;/sup&gt; FE3H significantly recovered hyperuricemia as much as 60.37, 62.24 and 65.572%, respectively. The LE3H and FE3H at the same dose showed that FE3H had a higher potential to restore hyperuricemia than LE3H. &lt;b&gt;Conclusion:&lt;/b&gt; Leave and fruit ethanolic extract of &lt;i&gt;E. hemisphaerica&lt;/i&gt; can potentially restore hyperuricemia in mice.

Leaf ethanolic extract of Etlingera hemesphaerica Blume mitigates defects in fetal anatomy and endochondral ossification due to mercuric chloride during the post-implantation period in Mus musculus

This study aimed to investigate the effectiveness of leaf ethanolic extract of Etlingera hemisphaerica (LE3H) in reducing defects in fetal anatomy and endochondral ossification in mice induced by HgCl₂ during the post-implantation period. Pregnant mice were divided into four groups, each consisting of 10 dams, and received drink and food ad libitum. The first group was administered LE3H (E1), the second one HgCl₂ (E2), the third one HgCl₂+LE3H (E3), and the fourth was control (E0), administered double-distilled water only. HgCl₂ (5 mg/kg bw) was administrated by injection intraperitoneally on gestation day (GD)9 and LE3H (0.39 mg/g bw) was administered by gavage on GD10. The treated and control animals were killed by cervical dislocation on GD18, dissected, and the morphologically normal living fetuses (MNLF) were collected. The MNLF of E0, E1, E2, and E3 from 5 dams were fixed with Bouin solution, and observed using the free hand razor blade technique for soft tissue examination. The remaining MNLF were fixed with 96% ethanol, and then stained with Alizarin Red S and Alcian Blue for ossification examination. Index of length of ossified part (ILOP) of humerus, index of width of ossified part (IWOP) of humerus, ILOP of femur, and IWOP of femur were calculated. E2 had higher cases of anatomical defects (74,6%) than E3 (48.9%), E1 (15.0%), and E0 (0%). E2 had humerus IWOP of 0.82±0.03, which was significantly lower than that of E0 (0.89±0.04) and E1 (0.89±0.03), while that of E1 and E0 was not significantly different from each other. Meanwhile, IWOP in E3 (0.88±0.03) was significantly higher than that in E2, but not different from that in E1 and E0. Thus, LE3H mitigated defects in fetal anatomy and endochondral ossification induced by HgCl₂ in mice.

Leaf ethanolic extract of Etlingera hemesphaerica Blume alters mercuric chloride teratogenicity during the post-implantation period in Mus musculus

This study aimed to investigate the effectiveness of leaf ethanolic extract of Etlingera hemisphaerica (LE3H) against the teratogenic effects of mercuric chloride (HgCl₂) in mice (Mus musculus). Pregnant M. musculus were divided into four groups, each consisting of 10 dams, and received drink and food ad libitum. The first, second, and third, and fourth (control) groups were administered with LE3H, HgCl₂, HgCl₂ + LE3H, and double-distilled water alone, respectively. HgCl₂ (5 mg/kg bw) was administered by injection on gestation day (GD) 9, and LE3H (0.39 mg/g bw) was administered by gavage on GD 10. Treated and control animals were killed by cervical dislocation on GD 18, dissected, and the fetuses were collected for evaluation of maternal, embryonic, and fetal toxicity. Eight parameters were measured: (a) embryo resorption or resorbed embryo, (b) dead fetus, (c) living fetus, (d) morphologically normal living fetus, (e) malformed living fetus, (f) number of MLF, (g) length of MNLF, and (h) weight of MNLF. LE3H caused 4 (50.00%), whereas HgCl₂ resulted in 7 (87.50%) parameters that were significantly different from those of the control, indicating that the teratogenicity of HgCl₂ was significantly higher than that of LE3H. HgCl₂ + LE3H showed two effects of LE3H on the teratogenicity of HgCl₂: increased 2 (25.00%), and decreased 6 (75.00%). Thus, LE3H decreased the teratogenic effects of HgCl₂ in M. musculus.
