The herbal composition Gyeongshingangjeehwan 18 (GGEx18), which is composed of three herbs, Laminaria japonica Aresch (Laminariaceae), Rheum palmatum L. (Polygonaceae), and Ephedra sinica Stapf (Ephedraceae), has been used as an anti-obesity drug in Korean local clinics. Thus, we investigated whether GGEx18 regulates obesity by suppressing appetite in high fat diet-induced obese C57BL/6J mice. Administration of GGEx18 to obese mice for 9 weeks significantly decreased body weight gain, epididymal adipose tissue weight, and food efficiency ratio. GGEx18 also caused a significant decrease in the circulating levels of leptin, which were increased by about 450% in obese control mice compared with normal lean mice. Concomitantly, GGEx18 decreased mRNA levels of a potent appetite-stimulating hormone neuropeptide Y, but increased an appetite-suppressing hormone pro-opiomelanocortin mRNA levels. These results suggest that GGEx18 may prevent obesity through regulating appetite in nutritionally obese mice.

In order to study the effects of bee venom herbal acupuncture on the neurotransmitters of the rat brain cortex, herbal acupuncture with the bee venom group and normal saline group was performed bilaterally on the point corresponding to LI 4 of the rat. The average optical density of the neurotransmitters from the cerebral cortex was analyzed 30 minutes after the herbal acupuncture with immunohistochemical methods. The results were as follows: 1. The density of NADPH-diaphorase in the bee venom group was increased significantly at the motor cortex, visual cortex, auditory cortex, cingulate cortex, retrosplenial cortex, and perirhinal cortex, compared to the normal saline group. 2. The average optical density of vasoactive intestinal peptide in the bee venom group had significant changes at the insular cortex, retrosplenial cortex, and perirhinal cortex, compared to the normal saline group. 3. The average optical density of neuropeptide-Y in the bee venom group increased significantly at the visual cortex and cingulate cortex, compared to the normal saline group.

Both brown and white adipose tissues (BAT/WAT) are innervated by the peripheral nervous system, including efferent sympathetic nerves that communicate from the brain/central nervous system out to the tissue, and afferent sensory nerves that communicate from the tissue back to the brain and locally release neuropeptides to the tissue upon stimulation. This bidirectional neural communication is important for energy balance and metabolic control, as well as maintaining adipose tissue health through processes like browning (development of metabolically healthy brown adipocytes in WAT), thermogenesis, lipolysis, and adipogenesis. Decades of sensory nerve denervation studies have demonstrated the particular importance of adipose sensory nerves for brown adipose tissue and WAT functions, but far less is known about the tissue's sensory innervation compared to the better-studied sympathetic nerves and their neurotransmitter norepinephrine. In this review, we cover what is known and not yet known about sensory nerve activities in adipose, focusing on their effector neuropeptide actions in the tissue.

Appetite-related neuropeptides proopiomelanocortin (POMC) and Neuropeptide Y (NPY) are essential for regulating feeding behavior and energy homeostasis. The objective of this study was to evaluate the effects of variants in POMC and NPY genes on growth, carcass and meat quality traits in rabbits. A total of six SNPs were identified for POMC (n = 2) and NPY (n = 4) genes by direct sequencing. Three SNPs were subsequently genotyped by using MassArray system (Sequenom iPLEXassay) in 235 individuals, which belong to three meat rabbit breeds, including 93 Ira rabbits; 81 Champagne rabbits and 61 Tianfu black rabbits. The SNP c.112-12G>T was in intron-exon boundaries (intron 1) of POMC gene, and the association analysis showed that individuals with TT genotype had a greater 84 d body weight (BW84), eviscerated weight and semi-eviscerated weight than those with GT genotype (p<0.05); the TT individuals were also higher than those GG in the ripe meat ratio (RMR) (p<0.05). The g.1778G>C SNP, which was in complete linkage with other three SNPs (g.1491G>A, g.1525G>T and g.1530C>T) in intron 1 of NPY gene, was significantly correlated with eviscerated slaughter percentage and semi-eviscerated slaughter percentage in rabbits, and the individuals with CC genotype had a better performance than CG genotype (p<0.05). These findings would provide primary clues for the biological roles of POMC and NPY underlying the rabbit growth-related traits.

This study was aimed to charily the change of NADPH-diaphorase(NADPH-d) and neuropeptide Y(NPY) associated with aging of the rots. To verily the effect of aging of NPY and NADPH-d-positive neurons in the brain stem, the neurons were stained by the immunohistochemical and histochemical method. In the aged group, the number of NADPH-d-positive neurons was significantly decreased in substantia nigra lateralis, supragenual nucleus, raphe magnus nucleus and raphe obscurus nucleus as compared with control group. The number of NADPH-d-positive neurons was not significantly decreased in superior colliculus, interpeduncular nucleus, central gray. dorsal raphe nucleus, retrorubral nucleus, pedunculopontine tegmental nucleus, laterodorsal tegmental nucleus, pontine reticular nucleus, prepositus hypoglossal nucleus and nucleus solitarius of the aged rats. The NADPH-d and NPY-positive neurons were found in the interpeduncular nucleus, central gray, substantia nigra lateralis, laterodorsal tegmental nucleus, nucleus solitarius, raphe magnus nucleus, raphe obscurus nucleus of the control and aged groups. The coexistence of NADPH-d and NPY in the some cell was not found in the brain stem of both groups.
