  • On January 6, 2010, two months earlier than normal breeding season, a red fox vixen was implanted with synthetic GnRH analogue, Deslorelin. Blood was sampled every 2~3 days from the day of implant to identifying spermatozoa on stains of epithelial cells. Estradiol and progesterone were examined. Even though the vixen was in non-breeding season, she was mated by a male fox. Pregnancy was confirmed by canine pregnancy detection kit that detect relaxin released from placenta. Four healthy pups were born on March 9, 2010. This is the first report showing synthetic GnRH can activate ovarian function and lead to fertile estrus of red fox in non-breeding season.

  • The purpose of this study was to examine the anti-metastatic effect of Juniperus chinensis extract by inhibition of galectin-3 expression. For this study, we carried out the experiment of galectin-3 expression assay and in vivo metastasis mouse model bearing colon 26-M3.1 lung carcinoma, and also MMP-1, MMP-2 and MMP-9 inhibitory assays relating metastasis mechanism. J. chinensis extract significantly showed the inhibitory effect of basal expression and MNNG-induced expression of galectin-3 in colon 26-M3.1 lung carcinoma at the all tested doses (5, 50 and $500{\mu}g/m{\ell}$). In case of the inhibition of MMP-1, MMP-2 and MMP-9, the weak activity was showed at the doses of 50 and $500{\mu}g/m{\ell}$ and was not detected at the dose of $5{\mu}g/m{\ell}$. However, J. chinensis extract significantly showed the anti-metastatic activity on mouse mode bearing colon 26-M3.1 lung carcinoma. Therefore, this study strongly suggests that J. chinensis is a potent inhibitor of galectin-3 expression, and holds great promise for use in inhibiting metastasis induced by elevated expression of galectin-3.

  • Pregnancy and puerperium are associated with significant changes in pschological and physiologic health status. Back and pelvic pain is common in pregnancy with prevalence figures in the range of $48\%-90\%$. The pain starts during pregnancy and often disappears soon after childbirth. But the prevalence of such pain four to six months post postpartum is report to be $25-40\%$. In $10-15\%$ of the case the pain become chronics, that is persisting for more than three months after childbirth. Low back pain and pelvic pain maybe caused by several factors related to changes that occur naturally during pregnancy. Changes in the center of gravity can create a strain on weight-bearing structures in bone. Pregnancy related hormones, relaxin, create general laxity of collagenous tissue. Another factor found to be a possible primary or contributing cause for law back and hip symptoms are leg length inequality, weight gain and changes in foot function. This article outlines the physiological and biomechanical changes that occur during pregnancy which have been reported to be possible causes of low back and pelvic pain And then, examination, diagnosis, evaluation and treatment of the woman during pregnancy are described. Standard treatment for low back pain and pelvic pain in pregnancy includes education in anatomy and kinesiology, back-strengthening exercise, training of the abdominal muscles and body posture correction. So, most woman during pregnancy require individual consultation and physiotherapist.
