The current study aims to extend our previous work to develop nonhuman primate model for prospectively studying the mechanism underlying premenstrual dysphoric disorder (PMDD). Thirty young dominant-status female monkeys were randomly divided into the control group, the model group, andJQPgroup. For two consecutive menstrual cycles, from day 18 to 22, monkeys in the model andJQPgroups were housed and immobilized singly in specially designed isolation cages for 5-6 hours per day. At the same time, the pharmaceutical interference effect ofjingqianping(JQP) granule, a traditional Chinese medicine specifically used to cure PMDD patients, was tested using monkeys in theJQPgroup. The behavior and facial expressions of monkeys were photographed with an automatic vidicon and were quantitatively analyzed by “the emotion evaluation scale of female experimental macaque.” Changes in serum level of progesterone and estradiol were measured with RIA, and serum level of 5-HT, noradrenaline, and dopamine were measured with HPLC. After experiencing mentioned above stress, 70% of monkeys of model group showed PMDD symptoms during three consecutive menstrual cycles. Estradiol and progesterone serum level decreased (P<0.01). Moreover, the peak value of secreted hormones in their follicular phase did not occur. Serum level of 5-HT and dopamine were significantly lower (P<0.01), but the serum noradrenaline level was higher (P<0.01). Moreover, in monkeys administered byJQPgranule, both PMDD symptoms and the anormal serum level of neurotransmitters could be obviously reversed. This special luteal-phase treatment on dominant-social-status monkeys might be a feasible way to create models mimicking PMDD.

Comprehensive Study

Hexachlorobenzene (HCB), a persistent and mobile organochlorine pesticide, occurs in environment. HCB has been shown to be present in human follicular fluid. An objective of the present report, which is part of a comprehensive study on reproductive toxicity of HCB, was to determine the cytologic effects of the compound on ovarian follicles in a primate model.Materials and Methods. Eight Cynomolgus monkeys were housed under controlled conditions at Animal facility of Health and Welfare, Ottawa. Animals were orally administered gelatin capsules containing HCB mixed with glucose in daily dosages of 0.0 or 10 mg/kg b.w. for 90 days; the former was the control group. On the menstrual period following completion of dosing, the monkeys underwent an induction cycle of superovulation. At necropsy, one-half of an ovary from each animal was diced into ca. 2- to 3-mm cubed specimens that were fixed by immersion in 2.5% glutaraldehyde in 0.1 M cacodylate buffer (pH 7.3). Subsequent procedures followed to obtain thin sections that were examined in a Hitachi H-7000 electron microscope have been described earlier.

Seventy-eight subjects, identified as possessing voice quality aberrations for six months, constituted four experimental groups: breathiness, harshness, hoarseness, and nasality. A control group included 38 subjects. The four experimental groups were compared with the control group according to personality characteristics and peer evaluations. The results of these comparisons indicated that there was no relationship between voice quality aberration and either personality characteristics or peer evaluations.

Ulcerative colitis is a chronic inflammatory disease mainly affects sigmoid colon and rectum. The inflammation process will activate NF-κB and leads to proinflamatory cytokine release such as Interleukin-6 (IL-6). Fig leaves contain a high level of flavonoid which can prevent NF-κB activation, and further inhibits IL-6 secretion. This research aims to see the preventive effect of methanolic extract of fig leaves towards colon histopathological feature and IL-6 serum level on ulcerative colitis induced mice. Balb/C male mice were randomly assigned into 5 groups (n=5). The treatment groups were dextran suphate sodium (DSS) control group (group I), methanolic extract of Fig leaves dose 28 mg/ day control group (group II), and methanolic extract of Fig leaves dose 7 mg/ day (group III), 14 mg/ day (group IV), and 28 mg/ day (group V) for 14 days, which at the 8th till 14th day were given DSS to induce colitis. The results showed that both of colon mucosal damage and IL-6 serum level of group I were significantly different from other groups (p=0,029). In  conclusion, the methanolic extract of Fig leaves can improve colon mucous damage and decrease IL-6 serum level on ulcerative colitis-induced mice. Keywords: ulcerative colitis, fig leaves, colon mucousal damage, interleukin-6

Endometriosis is a multifactorial disease that is manifested by infertility and pelvic pain. The purpose of the study was to evaluate the effect of progesterone treatment on the serum level of osteopontin, a multipotent cytokine, in patients with endometriosis. The study was prospective and we evaluated osteopontin levels that were measured in the serum of 40 patients with endometriosis and 12 healthy women using a standardized Enzyme-Linked Immunosorbent Assay (ELISA) kit. Osteopontin seric levels were lower in endometriosis patients and increased after progesterone treatment. Because of the large dispersion of data even in the control group, we find the association between osteopontin and endometriosis questionable.

Sjögren‘S Syndrome

Background and Aim: Lymphoid cell infiltration and destruction of exocrine glands, specifically lacrimal and salivary glands are characteristics of Sjogren’s syndrome (SS). An etiological role has been proposed for Helicobacter pylori (H. pylori), interacting in the clinical course and complications of SS (including gastric cancer and lymphoma). The aim of this study was to identify the probable correlation between H. pylori infection and Sjogren’s syndrome (SS). Methods: In this case-control study, ELISA method was used to determine serum level of IgA and IgM anti H. pylori antibody in 43 subjects with SS according to the international criteria and 95 healthy subjects as control. SPSS-17 was used to analyze data with t-test. P value <.05 were considered significant. Results: Serum level of IgM (34.9% vs. 10.5%, p-value= 0.001) and IgA (67.4% vs. 46.3% p value= 0.021) anti H. pylori antibody were significantly higher in SS patients compared to the control group. There was a positive correlation between age and H. pylori infection (r=0.2, Pvalue= 0.05). Conclusion: Patients with SS had a higher prevalence of H. pylori infection compared to the normal population. Eradication of H. pylori is recommended particularly in older patients with SS.

AbstractCells with non-alcoholic fatty liver disease (NAFLD) were studied to determine the mechanism of liver deficiency via the AdipoR2-PPARa pathway. NAFLD cells were randomly divided into a normal control group, blank control group, model group, low dose group, medium dose group, and high dose group. The NAFLD models were established by incubating the cells with linoleic acid (LA) and palmitic acid (PA) (2:1) for 24 h. The test groups were incubated with different doses of Shugan Xiaozhi Fang extract. The pathological changes in cells that accumulated lipids were detected by Oil Red O staining. Malondialdehyde (MDA) and triglyceride (TG) levels were measured. The apoptosis of cells was evaluated by flow cytometry. The levels of AdipoR2, PPARa, CD36, acyl-CoA mRNA, and protein were confirmed by RT- PCR and Western blot. The results of the Oil Red O staining demonstrated that the NAFLD cell model was successfully established. Compared with the model group, the levels of TG and MDA in the groups that received low, medium, and high doses of Shugan Xiaozhi were significantly lower (P<0.01), and a dose effect was evident. In addition, the expression of AdipoR2, PPARa, CD36, acyl-CoA protein, and mRNA in the Shugan Xiaozhi-treated groups was upregulated. Furthermore, the levels of AdipoR2, PPAR, CD36, acyl-CoA protein, and mRNA in all drug treatment groups that were extracted from L-O2 normal human hepatocytes were significantly upregulated (P<0.01). Moreover, the factor pattern of HepG2 human liver carcinoma cells was similar to that of L-O2. The levels of AdipoR, CD36, acyl-CoA, and AdipoR mRNA in the HepG2 low group were increased (P<0.05). AdipoR, PPAR, CD36, and acyl-CoA protein levels and AdipoR mRNA expression were significantly increased in the intermediate dose group and high dose group (P<0.01). Shugan Xiaozhi Fang attenuates hepatic lipid deposition in NAFLD induced by incubating with LA and PA for 24 h, which is associated with the activation of the AdipoR2-PPARα pathway.
