METHODS:TNBS was administered to rats at the following conditions:(1)with different doses(20,10,5 mg/0.8 mL per rat);(2)with same dose in different concentrations(20 mg/rat,25,50 mg/mL);(3)in different ethanol percentage(25%,50%);and(4)at depth either 4 cm or 8 cm from anus.At 5 d and 4 wk after TNBS administration,inflammation severity and inflammation resolution were evaluated.At 4 and 8 wk after TNBS application,visceral hyperalgesia and enterochromaffin(EC)cell hyperplasia were assayed by abdominal withdrawal reflex test,silver staining and capillary electrophoresis. RESULTS:Our results showed that:(1)TNBS induced dose-dependent acute inflammation and inflammation resolution.At 5 d post TNBS,the pathological score and myeloperoxidase(MPO)activity in all TNBS treated rats were significantly elevated compared to that of the control(9.48±1.86,8.18±0.67,5.78± 0.77 vs 0,and 3.55±1.11,1.80±0.82,0.97±0.08 unit/mg vs 0.14±0.01 unit/mg,P<0.05).At 4 wk post TNBS,the pathological score in high and median dose TNBS-treated rats were still significantly higher than that of the control(1.52±0.38 and 0.80±0.35 vs 0,P<0.05);(2)Intracolonic TNBS administration position affected the persistence of visceral hyperalgesia.At 4 wk post TNBS,abdominal withdrawal reflex (AWR)threshold pressure in all TNBS-treated groups were decreased compared to that of the control(21.52 ±1.73 and 27.10±1.94 mmHg vs 34.44±1.89 mmHg,P<0.05).At 8 wk post TNBS,AWR threshold pressure in 8 cm administration group was still significantly decreased(23.33±1.33 mmHg vs 36.79±2.29 mmHg,P<0.05);(3)Ethanol percentage affected the TNBS-induced inflammation severity and visceral hyperalgesia.In TNBS-25%ethanol-treated group,the pathological score and MPO activity were significantly lowered compared to that of the TNBS-50%ethanoltreated group,while AWR threshold pressure were significantly elevated(36.33±0.61 mmHg vs 23.33±1.33 mmHg,P<0.05);and(4)TNBS(5 mg/0.8 mL per rat, in 50%ethanol,8 cm from anus)-treated rats recovered completely from the inflammation with acquired visceral hyperalgesia and EC cell hyperplasia at 4 wk after TNBS administration.CONCLUSION:TNBS dosage,concentration,intraco-lonic administration position,and ethanol percentage play important roles in developing visceral hyperalgesia and EC cell hyperplasia of TNBS-induced PI-IBS rats.展开更多

Portal vein pressure (PVP) was measured at four time periods: before ligation, 2 wk, 6 wk and 10 wk postsurgery. Portal venography, blood sampling and liver and spleen pathological examinations were conducted at 10 wk after surgery.RESULTS: The PVP was 9.15± 0.58 cmH2O before ligation, and increased to 17.32 ±0.63 cmH2O 2 wk after PVL. By repeat measurement of the PVP in each rat, it was shown to remain elevated for 10 wk. There were no significant differences in the pressure measurements at 2 wk, 6 wk and 10 wk. Varices were found mainly in the mesenteric vein 2 wk after PVL, which were more obvious later, while these manifestations were similar at week 6 and week 10. Portal venography demonstrated the varices and collaterals. There was no significant change in liver pathology. The volume of the spleen was enlarged 2-fold after ligation, and the sinus of the spleen was enlarged due to congestion. Significant sinus endothelial cell proliferation was observed, but no evidence of hypersplenia was found on hemogram and biochemical examination.CONCLUSION: These findings suggest that a satisfactory prehepatic PHT rat model can be obtained by partial ligation of the portal vein, and this PHT rat model was stable for at least 10 wk.展开更多

Instead of therapeutic agents ...Benign prostatic hyperplasia (BPH) is an age-related disease of unknown aetiology characterized by prostatic enlargement coincident with distinct alterations in tissue histomorphology. Instead of therapeutic agents that can cause severe side effects, plant extracts are frequently used to treat BPH. In this study, we investigated whether the Melandrium firmum methanolic extract (MFME) improves BPH, using the testosterone propionate (TP)-induced BPH rat model. Castration was performed via the scrotal route under sodium pentobarbital anaesthesia. BPH in castrated rats was generated via daily subcutaneous injections of TP (3 mg kg-1) dissolved in corn oil, for 4 weeks. MFME was administered daily by oral garage at a dose of 200 mg kg-1 for 4 weeks, along with the TP injections. The control group received injections of corn oil subcutaneously. At the scheduled termination of the experiment, all rats were killed and their prostates weighed; the relative prostate weight (prostate/body weight ratio) was calculated, and histomorphological changes in the prostate were examined. Additionally, we measured the levels of testosterone and dihydrotestosterone (DHT) in the serum and the prostate. Experimentally induced BPH led to marked decreases in the relative prostate weight and the DHT levels in the serum and the prostate. Histologically, BPH was evident in the ventral lobe of the prostate, and MFME treatment suppressed the severity of the lesions. These results indicate that MFME effectively inhibits the development of BPH induced by testosterone in a rat model. Further studies will be needed to identify the compound(s) responsibility for inducing the protective effect against BPH and determine its mechanism of action,展开更多

In this study, a subacute aging rat model was established by continuous intraperitoneal injection of D-galactose and treated with Heshouwu decoction (a Chinese herb for tonifying the kidney, comprising Heshouwu pill, Herba Epimedii, Radix Salviae Miltiorrhiae, and Poria). Heshouwu pill treated rats were the positive control group. Radioimmunoassay, immunohistochemical staining, and western blot assay showed hypothalamic gonadotropin-releasing hormone, hypothalamic substance P, and serum gonadotropin levels to be significantly increased in the model rats; the concentrations of hypothalamic ~3-endorphin, and serum levels of insulin-like growth factor I and testosterone were significantly decreased. 1713- and 3[3-hydroxysteroid dehydrogenase expression in testicular tissue was also decreased. Intragastric administration of Heshouwu decoction at high (9.6 g/mL/100 g), medium (4.8 g/mL/100 g), and low (2.4 g/mlJ100 g) doses, Heshouwu decoction pretreatment at a medium dose (4.8 g/mL/100 g), and Heshouwu pill (2.06 g/mL/100 g) significantly reversed these changes. Heshouwu decoction pretreatment and high-dose Heshouwu decoction had the greatest anti-aging effects. These experimental findings indicate that Heshouwu decoction can improve hypothalamic-pituitary-testicular axis secretion in a subacute aging rat model, and prevent and delay gonadal axis aging, with an effect superior to that of Heshouwu pill.展开更多

文摘AIM: To study the stability of portal hypertension (PHT) caused by partial ligation of the portal vein ligation (PVL) in a rat model.METHODS: Thirty male adult Wistar rats were divided into two groups: 10 in Group Ⅰ received a sham operation; and 20 in Group Ⅱreceived partial PVL. Portal vein pressure (PVP) was measured at four time periods: before ligation, 2 wk, 6 wk and 10 wk postsurgery. Portal venography, blood sampling and liver and spleen pathological examinations were conducted at 10 wk after surgery.RESULTS: The PVP was 9.15± 0.58 cmH2O before ligation, and increased to 17.32 ±0.63 cmH2O 2 wk after PVL. By repeat measurement of the PVP in each rat, it was shown to remain elevated for 10 wk. There were no significant differences in the pressure measurements at 2 wk, 6 wk and 10 wk. Varices were found mainly in the mesenteric vein 2 wk after PVL, which were more obvious later, while these manifestations were similar at week 6 and week 10. Portal venography demonstrated the varices and collaterals. There was no significant change in liver pathology. The volume of the spleen was enlarged 2-fold after ligation, and the sinus of the spleen was enlarged due to congestion. Significant sinus endothelial cell proliferation was observed, but no evidence of hypersplenia was found on hemogram and biochemical examination.CONCLUSION: These findings suggest that a satisfactory prehepatic PHT rat model can be obtained by partial ligation of the portal vein, and this PHT rat model was stable for at least 10 wk.

文摘An increasing amount of evidence demonstrates the anti-aging effect of Heshouwu in pill form. In this study, a subacute aging rat model was established by continuous intraperitoneal injection of D-galactose and treated with Heshouwu decoction (a Chinese herb for tonifying the kidney, comprising Heshouwu pill, Herba Epimedii, Radix Salviae Miltiorrhiae, and Poria). Heshouwu pill treated rats were the positive control group. Radioimmunoassay, immunohistochemical staining, and western blot assay showed hypothalamic gonadotropin-releasing hormone, hypothalamic substance P, and serum gonadotropin levels to be significantly increased in the model rats; the concentrations of hypothalamic ~3-endorphin, and serum levels of insulin-like growth factor I and testosterone were significantly decreased. 1713- and 3[3-hydroxysteroid dehydrogenase expression in testicular tissue was also decreased. Intragastric administration of Heshouwu decoction at high (9.6 g/mL/100 g), medium (4.8 g/mL/100 g), and low (2.4 g/mlJ100 g) doses, Heshouwu decoction pretreatment at a medium dose (4.8 g/mL/100 g), and Heshouwu pill (2.06 g/mL/100 g) significantly reversed these changes. Heshouwu decoction pretreatment and high-dose Heshouwu decoction had the greatest anti-aging effects. These experimental findings indicate that Heshouwu decoction can improve hypothalamic-pituitary-testicular axis secretion in a subacute aging rat model, and prevent and delay gonadal axis aging, with an effect superior to that of Heshouwu pill.
