Ginsenoside Rg1-induced activation of astrocytes promotes functional recovery via the PI3K/Akt signaling pathway following spinal cord injury.

Aims: To determine whether ginsenoside Rg1 is involved in scratch wound healing through altered expression of related molecules in astrocytes and improved functional recovery after spinal cord injury (SCI).

Materials And Methods: Astrocytes were isolated from rats, followed by Rg1 treatment. The wound healing test was performed to observe the scratch wound healing in different groups.

Homochiral coordination polymers constructed from V-shaped oxybisbenzoyl-based amino acid derivatives: structures, magnetic and photoluminescence properties.

Five novel homochiral coordination polymers (HCPs) [Cu2(ODBALa)2(bpa)2H2O]·7H2O (1), [M(ODBALa)H2O]·H2O (M = Mn for 2; Co for 3), [Cu(ODBPRo)(bpe)]·7H2O (4) and [Cd2.5(ODBPRo)(HODBPRo)3(bpe)2.5]·13H2O (5) have been successfully synthesized by using designed chiral 4,4'-oxybisbenzoyl alanine/proline derivatives in the absence/presence of N-donor ancillary ligands, where H2ODBALa = 4,4'-oxybisbenzoyl-bis(l-alanine), H2ODBPRo = 4,4'-oxybisbenzoyl-bis(l-proline), bpa = 1,2-bis(4-pyridyl)ethane, and bpe = 1,2-bis(4-pyridyl)ethene.

Ginsenoside Rg1 Promotes the Migration of Olfactory Ensheathing Cells via the PI3K/Akt Pathway to Repair Rat Spinal Cord Injury.

The aim of this study was to determine the effects of ginsenoside Rg1 on the migration of olfactory ensheathing cells (OECs) in vitro, and its influence on the therapeutic efficacy of OECs transplanted in vivo for the treatment of spinal cord injury (SCI). Primary cultured and purified OECs (prepared from rats) were treated with ginsenoside Rg1. The wound healing test indicated that ginsenoside Rg1 promoted the migration of OECs.

Immunomodulatory effects of cinobufagin isolated from Chan Su on activation and cytokines secretion of immunocyte in vitro.

The objective of this study was to evaluate the immunomodulatory effects of cinobufagin (CBG) isolated from Chan Su (Venenum Bufonis) in vitro. In this paper, our results show that CBG significantly stimulated cell proliferation of splenocytes and peritoneal macrophages (PMΦ) and markedly enhanced the phagocytic activation of PMΦ. CBG also significantly increased CD4(+)CD8(+) double-positive T-cell populations and the percentage of S-phase cells of splenic lymphocytes.
