Uterine arteriovenous malformations are very rare but potentially life threatening lesions. These lesions may be congenital or acquired, but especially occur in patients with a history of curettage, abortion or pregnancy. Color doppler ultrasonography is the preferred method of diagnosing of arteriovenous malformations. In many cases, hysterectomies are performed. But if patients want pregnancies, embolization therapy and conservative treatment are effective therapy. We have experienced a clinical case of uterine arteriovenous malformation, which is presented with a brief review of literature.

In this study, a swirl hollow cone injector was designed to apply the Urea-SCR. In order to investigate the spray pattern and SMD of a swirl injector, the spray visualization was conducted by using the simple swirl injector, and the images of the spray cross-section were obtained from a sheet beam of ND-Yag laser and CCD camera. The SMD of the swirl injector was measured with the axial distance from the nozzle exit. The shape of the spray was converted from the hollow cone to solid cone along the distance from the injector exit. The spray angle is increased and the SMD is decreased with increasing injection pressure respectively.

The function of hPRL with respect to the reciprocal action with pituitary gonadotropin and with respect to menstrual and ovulatory problems hold an important role in the field of repoductive endocrinology. Furthermore, the study of the relation endocrinology. Furthermore, the study of the relation between the serum hPRL levels and the incidence of breast cancer has recently recieved increased attention. The study of the secretion pattern of hPRL and prolactin inhibitory agent is clinically signifi-cant in view of its possible potential to induce breast cancer. Studies have been reported concerning secretion mecha-nism of hPRL, in relation to growth hormone, catechola-mine, serotonin, adrenergic agent, LH-RH, TRH and hPRL. In addition, reports on prolaction inhibiting agents such as steroid, L-dopa, ergocryptine have been made in recent years. Because of difficulty of purification and measure-ent process in human pituitary prolactin, the study of hPRL has been delayed as compared with other pituitary hormones.

<P>This study examined the effects of baicalin, a bioactive flavonoid isolated from <I>Scutellariae Radix</I>, on carbon tetrachloride (CCl<SUB>4</SUB>)-induced liver injury. Mice were treated intraperitoneally with 0.5 ml/kg CCl<SUB>4</SUB> and different groups of animals received 25, 50, 100, and 200 mg/kg baicalin. At 24 h after the CCl<SUB>4</SUB> treatment, the level of serum aminotransferases and lipid peroxidation was significantly elevated, whereas the hepatic glutathione content was decreased. These changes were attenuated by baicalin. The histological studies showed that baicalin inhibited the portal inflammation, centrizonal necrosis, and Kupffer cell hyperplasia, which are the three most common characteristics of CCl<SUB>4</SUB>-induced liver damage. The serum level and mRNA expression of tumor necrosis factor-α were markedly increased by the CCl<SUB>4</SUB> treatment but suppressed by baicalin. The mRNA and protein expression levels of inducible nitric oxide synthase and heme oxygenase-1 increased significantly at 24 h after the CCl<SUB>4</SUB> treatment. Baicalin attenuated the increase in the protein and gene expression of inducible nitric oxide synthase but augmented the increase in those of heme oxygenase-1. These findings suggest that baicalin protects hepatocytes from the oxidative damage caused by CCl<SUB>4</SUB>, and this protection is likely due to the induction of HO-1 expression and the inhibition of the proinflammatory mediators.</P>

Purpose: Anterior cruciate ligament (ACL) injury is one of the most common injuries that occur in the knee, and ACL reconstruction (ACLR) is commonly performed for preventing aggravation of degenerative changes and restoring of knee stability in young, athletic patients. This metaanalysis has a purpose of evaluating the clinical and arthrometrical outcomes of ACLR in a group of middle age patients (40 years and older) and comparing with patients under 40 years of age. Methods: MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, Web of Science, and SCOPUS electronic databases were searched for relevant articles comparing the outcomes of ACLR between younger and older than 40 years of age until December 2016. Data searching, extraction, analysis, and quality assessment were performed based on the Cochrane Collaboration guidelines. Clinical outcomes were evaluated and compared between groups. The results were presented as mean difference for continuous outcomes with 95% confidence intervals whereas risk ratio for binary outcomes. Results: Seven studies were included in the meta-analysis. Based on International Knee Documentation Committee classification, side-to-side difference, Tegner activity score, Lysholm knee score, there were no significant clinical and mechanical differences between the groups. Conclusions: This meta-analysis confirmed that after ACLR, middle age (>40 years) and young age (<40 years) patients did not present with significant difference in clinical and arthrometric results.
