Current study was aimed to investigate the protective effect of berberine (BB) on the serum gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), inhibin B (INHB), testosterone (T) and alkaline phosphatase (Alk-p) activity in the testis of experimental varicocele-induced animals. For the current objective, 30 mature-male Wistar rats were randomly divided into control (n = 6 rats), control-sham (n = 6 rats) and experimental groups (n = 18 rats). The animals in the experimental groups were undergone experimental varicocele and simple laparotomy was conducted in control-sham group. 60 days after varicocele (VCL) induction the experimental group subdivided into: nontreated VCL-induced and 50 mg/kg and 100 mg/kg BB-treated groups (intra-peritoneally). Following 60 days, the animals were euthanized and serum levels of testosterone and testicular activity of alkaline phosphatase were measured. Non-treated VCL-induced animals indicated a significant (P < 0.05) reduction in serum levels of T and INHB and a remarkable (P < 0.05) increase in GnRH, FSH, LH and Alk-p activity compared to control and control-sham groups. Insignificant changes were found between control and control-sham groups. Meanwhile, each BB administered group showed a remarkable (P < 0.05) increase in serum levels of T and INHB and a significant (P < 0.05) decrease in GnRH, FSH, LH and alkaline phosphatase activity in testis tissue. According to the current findings, BB by increasing serum levels of testosterone and INHB increases the testicular endocrine capacity and protects Leydig cell against inflammatory and oxidant injury of varicocele. In addition, BB by inhibiting GnRH, FSH, LH and alkaline phosphatase activity, regulate

Evaluation of the antinociceptive effects of a selection of triazine derivatives in mice
Valiollah Hajhashemi,Ghadamali Khodarahmi,Parvin Asadi,Hamed Rajabi 대한통증학회 2022 The Korean Journal of Pain Vol.35 No.4
Background: The authors showed in a previous study that some novel triazine derivatives had an anti-inflammatory effect. The present study was designed to evaluate the antinociceptive effect of five out of nine compounds including two vanillintriazine (5c and 5d) and three phenylpyrazole-triazine (10a, 10b, 10e) derivatives which showed the best anti-inflammatory effect. Methods: Male Swiss mice (25–30 g) were used. To assess the antinociceptive effect, acetic acid-writhing, formalin, and hot plate tests were used after intraperitoneal injection of each compound. Results: All compounds significantly (P < 0.001) reduced acetic acid-induced writhing at tested doses (50, 100, and 200 mg/kg). Also, the percent inhibition of writhing in the acetic acid test showed that at the maximum tested dose of these compounds (200 mg/kg), the order of potencies is as follows: 10b > 10a > 10e > 5d > 5c. In the formalin test, compounds 5d, 10a, and 10e showed an antinociceptive effect in the acute phase and all compounds were effective in the chronic phase. In the hot plate test, compounds 5c, 5d, and 10a demonstrated an antinociceptive effect. Conclusions: The results clearly showed that both vanillin-triazine and phenylpyrazole- triazine derivatives had an antinociceptive effect. Also, some compounds which showed activity in the early phase of formalin test as well as in the hot plate test could control acute pain in addition to chronic or inflammatory pain.
