No effective therapy has yet developed for liver fibrosis/cirrhosis by directly inhibiting the accumulation of extracellular matrix. This study was undertaken to determine the effect of tetrandrine in rat model of liver fibrosis induced by carborn tetrachloride (CCl4) administration intraorally. Tetrandrine, a calcium channel blocker, is anti-inflammatory constituent of the families Menispermaceae and Ranunculaceae, which have been used as folk remedies in China. Repeated administration of CCl4 for 14 weeks to rats induced liver fibrosis with steatosis. Rats were killed after 4, 8 or 14 weeks of treatment with CCl4, CCl4 tetrandrine (30 mg/kg) or CCl4 tetrandrine (50 mg/kg). The histopathological findings of liver were observed semi-quantitatively by light microscopy and volume percentage of the collagen deposition was determined by image analyzer. Tetrandrine inhibited collagen deposition induced by CCl4 administration, as shown by less severe steatosis and fibrosis and significantly decreased volume percentage of collagen fibers in CCl4 tetrandrine treated animals compared with CCl4 only group. Thus, the administration of tetrandrine holds great promise for treating subjects with liver fibrosis/cirrhosis as a result of chronic hepatic injury.

Myocardial ischemia occurs when myocardial oxygen availability is inadequate to meet metabolic requirements. The common cause of myocardial ischemia is atherosclerotic epicardial coronary arteries. Isoflurane is a potent small vessel-type coronary vasodilator and has the potential for causing regional myocardial ischemia in patients with coronary disease, but it's still controversial. We experienced a case of transient myocardial ischemia during general anesthesia with isoflurane. The patient was a 51 year- old male who underwent a direct clipping of an anterior communicating artery aneurysm. There was no specific abnormality on preoperative laboratory tests except for mild mitral valve regurgitation on the cardiac echocardiogram. He had once experienced several minutes of sudden severe chest tightness just 3 months before admission, but it had subsided without any specific treatment. One hour after beginning of operation, abnormal EKG changes such as ST-T elevation, QRS widening, VPC, ventricular tachytcardia and ST-T depression appeared and then normalized within 2 minutes with stopping isoflurane and using isosorbide dinitrate. He discharged 12 days later without complications. After discharge, Tread-mill test, SPECT and 2D echocardiogram were performed but there was no any evidence of coronary artery disease.

OBJECTIVE: To evaluate the effect of a gonadotropin-releasing hormone (GnRH) antagonist protocol using corifollitropin alfa in women undergoing assisted reproduction. METHODS: Six hundred and eighty-six in vitro fertilization-embryo transfer (IVF)/intracytoplasmic sperm injection (ICSI) cycles were analyzed. In 113 cycles, folliculogenesis was induced with corifollitropin alfa and recombinant follicle stimulating hormone (rFSH), and premature luteinizing hormone (LH) surges were prevented with a GnRH antagonist. In the control group (573 cycles), premature LH surges were prevented with GnRH agonist injection from the midluteal phase of the preceding cycle, and ovarian stimulation was started with rFSH. The treatment duration, quality of oocytes and embryos, number of embryo transfer (ET) cancelled cycles, risk of ovarian hyperstimulation syndrome (OHSS), and the chemical pregnancy rate were evaluated in the two ovarian stimulation protocols. RESULTS: There were no significant differences in age and infertility factors between treatment groups. The treatment duration was shorter in the corifollitropin alfa group than in the control group. Although not statistically significant, the mean numbers of matured (86.8% vs. 85.1%) and fertilized oocytes (84.2% vs. 83.1%), good embryos (62.4% vs. 60.3%), and chemical pregnancy rates (47.2% vs. 46.8%) were slightly higher in the corifollitropin alfa group than in the control group. In contrast, rates of ET cancelled cycles and the OHSS risk were slightly lower in the corifollitropin alfa group (6.2% and 2.7%) than in the control group (8.2% and 3.5%), although these differences were also not statistically significant. CONCLUSION: Although no significant differences were observed, the use of corifollitropin alfa seems to offer some advantages to patients because of its short treatment duration, safety, lower ET cancellation rate and reduced risk of OHSS.

The t(3;21) (q26;q22) is associated with chronic myelogenous leukemia in blast crisis, leukemia evolving from therapy-related myelodysplasia, and with leukemia following other hematopoietic proliferative diseases. The t(3;21) is rare secondary aberration in blast crisis of Philadelphia(Ph)-positive chronic myeloid leukemia, which may be restricted to patients entering myeloid blast crisis. We report here in one case of chronic myeloid leukemia in blast crisis which reveals both t(9;22) (q34;q11), and t(3;21) (q26 ;q22). A 62-year-old male was diagnosed as chronic myeloid leukemia 5 years ago, received hydroxyurea therapy, and admitted because of gingival bleeding and fever. On examination, splenomegaly and leukocytosis with proliferated blasts(91%) in peripheral blood were noted. Bone marrow aspirate showed hypercellularity with severe blast proliferation(92.5%) which revealed all negative in peroxidase and PAS stain. Cytogenetic study of bone marrow cells showed the karyotype 46, XY, t(3;21) (q26;q22), t(9;22) (q34;q11), which might be suspected as myeloid blast crisis. Above finding was confirmed by the result of immunophenotyping(CD13 43.6%, CD34 68.2%, HLA-DR 91.6%). He received intensive chemotherapy, but still sustained proliferation of blasts was noted . The follow up cytogenetic study was as follows: 46, XY, 4(3;21) (q26:22), t(9;22) (q34;q11)/46, XY, t(3;21)(q26;q22), del(8) (q22), t(9:22) (q34,q11)/46, XY (16/3/1). He died soon from severe pancytopenia and sepsis.
