The Japanese pond smelt (Hypomesus nipponensis) stock has been observed to fluctuate quite rigorously over the years with sustained periods of low catch in Lake Kasumigaura and Kitaura of the Ibaraki prefecture, Japan which would adversely affect the socioeconomic livelihood of the local fishermen and fisheries industry. This study was aimed at determining the factors affecting the stock fluctuation of the pond smelt through the different years in the two lakes. Through exploratory analysis it was found that the pond smelt had significant relationship with total phosphorus (TP) level in both lakes. The global mean land and ocean temperature index (LOTI) was also found to be indirectly related to the pond smelt stock in lake Kasumigaura and Kitaura at the latitude band of 24°N to 90°N (l). Both TP and LOTI had inverse relationship with pond smelt trajectory in both lakes. For both Lake Kasumigaura and Kitaura, TP for the individual lakes and LOTI (l) were used as independent variables using generalized linear model and response surface methods for modeling the stock dynamics of the pond smelt in the two lakes. Model selection was based on significant parameter estimates (p < 0.05), Akaikes Information Criterion and R2 values. Phosphorus loading is an indication of increasing anthropogenic activities in the surrounding area having negative impact on the pond smelt population. When management decisions are being made regarding pond smelt fishery and sustainability plans in the Ibaraki prefecture, the effects of TP and LOTI should be taken into account. Future research needs to be directed towards deeper understanding the mechanisms by which TP and LOTI affect pond smelt population in Lake Kasumigaura and Kitaura for more effective management.

Acupuncture Points for Treating Parkinson's Disease Based on Animal Studies

Parkinson＇s disease （PD） is a well-known neurodegenerative disease caused by dopaminergic cell death in the nigrostriatal pathway. Recent studies have shown that acupuncture can be a potential therapy for the treatment of PD, but it is not clear which acupuncture points （acupoints） play major roles in reliving symptoms of PD. Yanglingquan （GB 34）, Zusanli （ST 36）, Fengfu （GV 16）, Taichong （LR 3）, Baihui （GV 20） and Dazhui （GV 14） acupoints have frequently been to investigate the effectiveness and action mechanism of acupuncture for treating PD, but it is not clear why they were selected. This review summarizes the current understanding of the acupoints for PD treatment based on Oriental medicine theories and on the accumulated findings from previous animal studies. The results of this study will be useful to development of a strategy for future research in this field.

Changes in Small Intestinal Motility and Related Hormones by Acupuncture Stimulation at Zusanli(ST 36) in Mice

引用

Chinese Journal of Integrative Medicine 2017年第3期23卷 215-220页

作者： Jung-Hee Jang Deuk-Joo Lee Chang-Hwan Bae Ki-Tae Ha sunoh Kwon Hi-Joon Park Dae-Hyun Hahm Hyejung Lee Seungtae Kim School of Korean Medicine Pusan National University Acupuncture and Meridian Science Research Center Kyung Hee University Department of Psychiatry and Behavioral Sciences Northwestern University Feinberg School of Medicine

Objective： To clarify the effects of acupuncture stimulation at Zusanli（ST 36） on the hormonal changes. Methods： Eight-week-old male C57BL/6 mice received acupuncture stimulation at acupoint ST 36 or Quchi（LI 11） once a day for 3 or 5 days in the acupuncture-stimulated groups, but not received in the normal group（n=6 in each group）. On day 3 or 5, animals were given 0.1 m L of charcoal orally with a bulbed steel needle, 30 min after the last acupuncture stimulation. Ten minutes later, mice were anesthetized, and the intestinal transit and the concentrations of vasoactive intestinal peptide（VIP）, motilin, ghrelin and gastrin in the serum were measured. Results： Compared to no acupuncture stimulation, acupuncture stimulation at ST 36 for 5 days increased the intestinal transit and down-regulated the concentration of VIP and up-regulated the concentrations of motilin, ghrelin and gastrin（P〈0.05 or 0.01）, whereas acupuncture stimulation at LI 11 did not change them significantly（P〉0.05）. Conclusion： Acupuncture stimulation at ST 36 for 5 days enhances the small intestinal motility and regulates the secretion of hormones related to small intestinal motility.
