Objective. Primary dysmenorrhea (PD) is a common and high incidence disease in gynecology, which seriously affects the quality of life in young women. Our previous study found that mild moxibustion could treat abdominal pain of PD patients, but the mechanism is still unclear. Therefore, this study aims to partly investigate the treatment mechanism of moxibustion for PD, especially on uterine microcirculation. Methods. Forty 3-month-old Sprague Dawley female rats were randomly divided into four groups, including group A (saline control group, n = 10), group B (control plus moxibustion group, n = 10), group C (PD model group, n = 10), group D (PD. model plus moxibustion group, n = 10). The PD rat model was established by injecting estradiol benzoate and oxytocin. Mild moxibustion on Sanyinjiao (SP6) and Guanyuan (CV4) acupoints was once a day, 20 minutes per time, for 10 consecutive days. A vaginal smear was used to test the estrous cycle of rats. Uterine microvascular thickness was observed by stereomicroscope. And we detected the content of prostaglandin F2α (PGF2α) and prostaglandin E2 (PGE2) in uterine tissue by enzyme-linked immunosorbent assay. Results. Mild moxibustion can enlarge the microvessels, improve the microcirculation disturbance, and relieve the swelling of the uterus in PD rats. During the mild moxibustion intervention, the contents of PGF2α and PGE2 in uterus issues were synchronous increases or decreases and the changes of PGE2 were more obvious, but the changes of uterine microvasculature and morphology caused by the decrease of PGF2α were greater than PGE2. Conclusion. Mild moxibustion at SP6 and CV4 acupoints may relax uterine microvascular obstacle by reducing the content of PGF2α in uterine tissue, improve the microcirculation disorder, and then alleviate the PD rat’s uterine swelling.

Objectives. To evaluate the therapeutic effects of moxibustion at Shenshu (BL-23) and Geshu (BL-17) acupoints in a focal segmental glomerulosclerosis (FSGS) model in rats. Methods. A FSGS rat model was established by single nephrectomy and repeated injection of doxorubicin. The FSGS rats were randomly divided into the model group, losartan (positive control) group, Shenshu moxibustion group, and Geshu moxibustion group. Molecular indicators of kidney function and renal pathological changes were monitored. Results. Urinary protein, serum creatinine, urea nitrogen, and serum uric acid were significantly reduced after 12-week intervention with losartan, Shenshu, or Geshu moxibustion. Renal α-SMA, FN, and TGF-β were also decreased, while podocin and nephrin protein and mRNA were increased. The pathological damage in renal tissue was obviously alleviated by all three treatments, which suggests that moxibustion may have similar efficacy to losartan in the treatment of FSGS. Conclusion. Moxibustion alleviates podocyte injury and inhibits renal interstitial fibrosis in the FSGS rat model, thereby minimizing the progression of glomerular sclerosis and improving renal function.

Abstract Background: Premature ovarian failure is among the most important side effects of chemotherapy during reproductive period. Preserving ovarian function is gradually gaining importance during oncologic treatment. The present study aims to investigate the potential of melatonin to protect from cisplatin-induced ovarian toxicity in rats. Twenty nine female rats were divided to three groups: Saline control group (Group 1), cisplatin group (Group 2), and cisplatin+melatonin group (Group 3). While the rats in Groups 2 and 3 were administered 5 mg/kg single dose of cisplatin via intra-peritoneal (IP) route, the rats in Group 3 were started on melatonin (20 mg/kg IP) before cisplatin administration and continued during 3 consecutive days. Ovaries were removed one week after cisplatin administration in all groups. Blood samples were obtained before the rats were decapited. Histological evaluation, follicle count, and classification were performed. TAp63 mRNA expression was evaluated using mRNA extraction and real-time polymerase chain reaction (PCR) method. Serum estradiol (E2) and anti-mullerian hormone (AMH) values were measured with enzyme immune-assay technology. Results: While primordial follicles were seen to decrease in Group 2 as compared to Group 1 (p:0.023), primordial follicle count was observed to be preserved significantly in melatonin group as compared to Group 2 (p:0.047). Moreover, cisplatin-induced histo-pathological morphology was preserved in favor of normal histology in melatonin group. A significant difference was not observed between groups with regard to mean serum AMH and E2 values (p:0.102 and p:0.411, respectively). While TAp63 gene expression significantly increased in Group 2 as compared to control group (p:0.001), we did not detect a statistically significant difference in cisplatin+melatonin group, although gene expression decreased (p:0.34). Conclusion: We conclude that concurrent administration of melatonin and cisplatin may protect from ovarian damage.

Background: Moxibustion treatment has been found to ameliorate clinical symptoms including abdominal pain, diarrhoea and constipation in patients with irritable bowel syndrome (IBS). Herein we investigated the mechanisms underlying the use of moxibustion in a rat model of IBS. Methods: In our study, an IBS model was established in rats by colorectal distension (CRD) stimulus and mustard oil enema. The rats were randomly divided into a normal group, model group, mild moxibustion group, electroacupuncture group, probiotic group and dicetel group. Abdominal withdrawal reflex (AWR) scores were determined within 90 min of the last treatment. The expression of GDNF/GFRα3 protein and mRNA in the colon and spinal cord were detected by immunohistochemistry and quantitative real-time-PCR, respectively. Results: The IBS model rats had significantly higher AWR scores than the normal group ( P<0.01). After mild moxibustion treatment, the AWR score was significantly reduced (20 mm Hg, P<0.05; 40 mm Hg, 60 mm Hg and 80 mm Hg, P<0.01). The model group showed significantly more colonic glial cell line-derived neurotrophic factor (GDNF/GFRα3 (GDNF family receptor α3) protein and mRNA expression in the colon and spinal cord than the normal group ( P<0.01). Compared with the model group, the expression of GDNF/GFRα3 protein and mRNA in the colon and spinal cord of the rats were significantly decreased in the mild moxibustion group (colon: GDNF and GFRα3 protein, P<0.01; GDNF and GFRα3 mRNA, P<0.01; spinal cord: GDNF and GFRα3 protein, P<0.01; GDNF mRNA, P<0.05, GFRα3 mRNA, P<0.01). Conclusions: Our data suggest that moxibustion therapy may mitigate CRD-induced increases in the expression of GDNF and its receptor GFRα3 in the colon and spinal cord in a rat model of IBS.

Background: Tearing and degeneration of the rotator cuff at the tendon-to-bone junction are common in adults aged ≥50 years. Few studies have reported on the relationship between estrogen and the rotator cuff enthesis. In addition to preventing bone loss, selective estrogen receptor modulators have been shown to improve tendon and muscle quality. Purpose: To evaluate the effects of raloxifene (RLX) and vitamin D on rotator cuff tendon-to-bone healing in a rat model. Study Design: Controlled laboratory study. Methods: A total of 29 female rats (58 shoulders) were assigned to 4 groups: (1) control group, (2) ovariectomy (OVX)–only group, (3) no RLX group (OVX and rotator cuff repair [RCR]), and (4) RLX group (OVX, RCR, and RLX). Rats that did not undergo rotator cuff tear (RCT) surgery were divided into the control and OVX-only groups according to OVX surgery. Rats that underwent RCT surgery and RCR were divided into the no RLX and RLX groups according to RLX and vitamin D administration. An estrogen-deficient state was induced by OVX at 12 weeks of age. Bone mineral density (BMD) and trabecular bone characteristics were measured by micro–computed tomography, and healing of the tendon-to-bone junction was evaluated by biomechanical testing, histomorphometry, and micro–magnetic resonance imaging (MRI). Results: The mean final body weight (BW; 461.6 ± 47.3 g) of the OVX-only group was significantly higher and BMD (0.25 ± 0.07 g/cm3) was significantly lower ( P < .001) than the mean final BW (338.5 ± 35.1 g) and BMD (0.48 ± 0.05 g/cm3) of the control group. In contrast, the RLX group showed that the BW (369.6 ± 35.8 g) and BMD (0.41 ± 0.08 g/cm3) were not significantly different from the control group. The RLX group had a significantly higher histomorphometric total score (8.50 ± 1.05) than the no RLX group (4.83 ± 2.48). On biomechanical testing, the RLX group (29.7 ± 9.1 N) showed a significantly higher load to failure than the no RLX group (19.4 ± 8.8 N). On micro-MRI, the RLX group had a more homogeneous low signal and tendon continuity than the no RLX group. Conclusion: The combination treatment of RLX and vitamin D prevented a decrease in local BMD (greater tuberosity of the proximal humerus) and enhanced tendon-to-bone healing of the rotator cuff in a rat model. Clinical Relevance: This study induced an estrogen-deficient state similar to the human postmenopausal state and used drugs that are actually being prescribed in a clinical situation.

The intestine function recovery decoction (IFRD) is a traditional Chinese medicine that has been used for the treatment of adhesive intestinal obstruction. In this study, the preventative effects and probable mechanism of the IFRD were investigated in a rat model. We randomly assigned rats to five groups: normal, model, control, low dose IFRD, and high dose IFRD. In the animal model, the caecum wall and parietal peritoneum were abraded to induce intra-abdominal adhesion formation. Seven days after surgery, adhesion scores were assessed using a visual scoring system, and histopathological samples were examined. The levels of serum interleukin-6 (IL-6) and transforming growth factor beta-1 (TGF-β1) were analysed by an enzyme-linked immunosorbent assay (ELISA). The results showed that a high dose of IFRD reduced the grade of intra-abdominal adhesion in rats. Furthermore, the grades of inflammation, fibrosis, and neovascularization in the high dose IFRD group were significantly lower than those in the control group. The results indicate that the IFRD can prevent intra-abdominal adhesion formation in a rat model. These data suggest that the IFRD may be an effective antiadhesion agent.

High-mobility group box 1 (HMGB1), a highly conserved non-histone chromosomal protein, was found to act as a potent proinflammatory cytokine and a mediator that participated in the development of systemic inflammatory response. Forty wild type C57BL/6 male (25-30gms) mice were randomly divided into three groups: saline control group; anti-HMGB1 antibody treated group and untreated group. Each group received intratracheal instillation twice per week for 4 consecutive months. 24 hours after the last exposure, anaesthetize the mice with chloral hydrate, bronchoalveolar lavage fluid was collected for cytokines analysis were measured by enzyme linked immunosorbent assay (ELISA). The level of the HMGB1 in lung tissue was determined by real-time PCR and western blot. Lung were fixed with 4% paraformaldehyde for histopathological detection. The serum level of HMGB1 increased after lung injury [peaked 2-5 hr] after lung injury, furthermore this upregulation in HMGB1 associated with increased proinflammatory cytokines [TNF-α, IL-6, IL-1β]. The injection of anti-HMGB1 antibody suppressed inflammatory reaction and improved the survival rate compared with control mice [71.3% vs. 29.4% P=0.031]

Background: The present study aims to evaluate the therapeutic action of Sepia pharaonis ink extract in experimentally induced polycystic ovary syndrome (PCOS) rat model and perform Immunohistochemistry to confirm the findings.Methods: The female rats were grouped into 5 consisting of six animals each. Only water was given to the control group. For inducing PCOS, Letrozole 1mg/kg.b.wt was administered to the subsequent four groups for 21 days. To the third group, an allopathic drug, clomiphene citrate 1mg/kg was given for 19 days after PCOS induction. The SPIE was subjected to lyophilisation to make a black powder and next two groups were administered orally with two different dosages of SPIE (100mg and 200mg respectively) mixed with water after PCOS induction. Vaginal smears were taken from all groups till 21 days and then treatment was started with clomiphene citrate (CC) and SPIE. After 21 days, vaginal smears were taken from all groups till ovulation was induced. The test drug effects were studied using ovary weight both right and left, body weight, hormonal levels, histopathology of ovary and Immunohistochemistry. Result: PCOS group showed rapid increase in the ovarian weight when compared to control and was reduced by CC and SPIE treatment. The levels of progesterone and estradiol were found lower and testosterone levels were found higher in PCOS rats which were favourably altered. Vaginal smears coincided with the histopathology and immunohistochemistry findings. SPIE can be used as a therapeutic drug for PCOS in future, reduce infertility complaint of females and prevent early inception of diabetes mellitus.

Abstract. Yuliawati D, Astuti WW, Yuniarti F. 2020. Effects of Black Soy phytoestrogens (Glycine soja) on elevated levels of estradiol in Rat Blood (Rattus norvegicus) ovariectomy. Nusantara Bioscience 12: 55-58. Menopause is the transition from productive to non-productive times due to reduced estrogen and progesterone and has an impact on improving cardiovascular problems. The fulfillment of estrogen needs in menopause can use a type of phytoestrogens from black soybeans. The purpose of research is to prove the administration of black soy extract (Glycine soja) can increase the levels of estradiol in the rat blood (Rattus norvegicus) ovariectomy. Design research uses post-test only control group design. Twenty-five female rats were randomly divided into 5 groups (n = 5 tails per group), negative controls, positive and 3 treatments. Ovariectomy was performed in a group of positive controls and treatment. Thirty-day post ovariectomy rats were given appropriate group treatment (negative control, positive, and treatment with the administration of black soy extract dose of 50, 100, 150 mg/200  g/day for 30 days). The estradiol test used the Enzyme-linked immunosorbent assay (ELISA). Anova's test results with a significant degree of α = 0.05 established that the p-value of 0.000 was less than α = 0.05, meaning there was a significant effect of giving black soy extract on increased levels of estradiol in the rat blood ovariectomy. Post - Hoc Tukey testing shows increased the highest estradiol levels in the dose treatment group 100 mg/200  g/day. This research proves that the administration of black soy extract (Glycine soja) can increase the levels of estradiol in the rat blood (Rattus norvegicus) ovariectomy.

Abstract. Background: We investigated the association of the 5A/6A polymorphism in the promoter region at -1612 of the matrix metalloproteinase-3 gene (MMP-3-1612) and deep venous thrombosis (DVT). Patients, materials and methods: The distribution of the MMP-3 (-1612 5A/6A) polymorphism in the case and control groups was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Serum MMP-3 level of two groups was detected using enzyme-linked immunosorbent assay (ELISA). HepG2 cells containing MMP-3-1612 recombinant plasmid were cultured in vitro and the MMP-3 level was defined by luminescence intensity of luciferase. A DVT rat model was built. Serum MMP-3 level in the rats’ wounded vein at different time points was detected by ELISA and recorded for investigation of the association between MMP-3 and DVT. Statistical data analysis was conducted with SPSS18.0. Results: On the basis of the observation of MMP-3-1612 genotype frequency and allele frequency in the case and control groups, we identified significantly higher MMP-3-1612 5A allele frequency and higher serum MMP-3 level in the case group than in the control group (both P < 0.05). According to in vitro luciferase measurements, the 5A allele had higher transcriptional activity than the 6A allele. As observed in the rat model, serum MMP-3 level increased with time passing and thrombosis formation after modelling. Conclusions: The MMP-3-1612 5A/6A polymorphism may effect serum MMP-3 level and over-expression of serum MMP-3 level may be a risk factor for DVT formation.

<b><i>Introduction:</i></b> Hyperpolarization-activated cyclic nucleotide-gated (HCN) channel currents of <i>Ih</i> and absence epilepsy seizures are associated, but studies reveal differential results. <b><i>Objective:</i></b> In our study, we aimed to investigate the role of the HCN channels on the expression of spike-and-wave discharges (SWDs) using the Genetic Absence Epilepsy Rats from Strasbourg (GAERS) model. <b><i>Methods:</i></b> HCN isoform levels from isolated brains of both naïve nonepileptic Wistar and GAERS groups were evaluated by enzyme-linked immunosorbent assay. ZD7288, an <i>Ih</i> inhibitor as well as an HCN channel antagonist, was administered intracerebroventricularly to the adult GAERS groups, and to evaluate their SWD activities, electroencephalography was recorded. The effect of ZD7288 on the cumulative total duration and number of SWDs and the mean duration of each SWD complex was evaluated. <b><i>Results:</i></b> The HCN2 levels in the cortex and hippocampus of the GAERS group were lower compared to the naïve nonepileptic Wistar group (<i>p</i> &#x3c; 0.05). ZD7288 increased the number of SWDs at the 20th and 120th min with the highest administered dose of 7 μg (<i>p</i> &#x3c; 0.05). <b><i>Conclusion:</i></b> The <i>Ih</i> inhibitor ZD7288 increased the number of SWDs in a genetic absence epilepsy rat model, although this increase may not be significant due to the inconsistent time-dependent effects. In GAERS, the cortical and hippocampal HCN2 channel levels were significantly lower compared to the control group. Further studies are needed with higher doses of ZD7288 to determine if the effects will increase drastically.
