{"title":"Role of Flutamide on Testosterone Induced Prostatic Hyperplasia in Long Evans Rats","authors":"Atiar Rahman, H. Naushaba, Jesmin Akter, U. Paul, N. A. Khan","doi":"10.3329/BJA.V8I1.6104","DOIUrl":"https://doi.org/10.3329/BJA.V8I1.6104","url":null,"abstract":"Context: Testosterone is the male sex hormone responsible for growth of secondary sexual character and accessory sex organs. Despite the effectiveness as a male sex hormone, testosterone causes Benign Prostatic Hyperplasia (BPH) resulting in urinary dysfunction. On the other hand, flutamide is a pure antitestosterone, which blocks the effects of Dihydro testosterone (DHT) at the testosterone receptor and prevents BPH. Therefore the present study was designed to observe the protective role of flutamide on testosterone induced prostatic hyperplasia. Objective: To observe the effects of flutamide on testosterone induced prostatic hyperplasia in Long Evans rats. Study design: An experimental study. Place and period of study: The study was carried out in the Department of Anatomy, Sir Salimullah Medical College, Dhaka during the period of July 2006 to June 2007. Materials & Methods: Forty five matured male long Evans rats of age 8-10 weeks and weighing 200-300 gms were used in this study. They were divided into three equal groups. Group A was vehicle (olive oil) control group, Group B was testosterone treated group and Group C was testosterone & flutamide treated group. Comparative study in different groups were done microscopically. Results: There was significant reduction (P<0.001) in prostatic hyperplasia. The mean percentage volume of stroma in flutamide treated rats was lower than the testosterone treated rats. Conclusion: It can be concluded from this study that flutamide is an effective drug against testosterone induced prostatic hyperplasia. Key words: Prostate; Testosterone; Flutamide.

Though it is effective drug in various diseases, indomethacin causes inhibition of spermatogenesis by lowering the pH of seminal fluid leading to infertility. On the other hand, vitamin E enhances spermatogenesis by increasing pH of the seminal fluid. Therefore, the present study was designed to observe the protective role of vitamin E on indomethacin induced low pH of seminal fluid in testicular damage. Objective: To observe the effects of vitamin E on indomethacin induced low pH of seminal fluid in testicular damage in Long Evans rats. Study design: An experimental study. Place and period of study: The study was carried out in the Department of Anatomy, Sir Salimullah Medical College, Dhaka in the period of August, 2005 to June, 2006. Materials and methods: Eightyfour mature Long Evans male rats were divided into four groups (I, II, III and IV). The rats of group I, II and III were treated with indomethacin at different doses and duration. Group IV rats were treated with indomethacin plus vitamin E at different doses for 49 days. The pH of seminal fluid were measured biochemically. Results: There was significant reduction (P<0.001) of pH of seminal fluid when the rats were treated with indomethacin at low (2 mg/kg body weight/day) and high (10 mg/kg body weight/day) doses for 7, 14 and 42 days, respectively. On the other hand, rats treated with indomethacin plus vitamin E for 49 days showed increase in pH of seminal fluid compared to other groups (P<0.001).

A questionnaire with 16 statements was given to these students and their answers were compiled. The results of this study were encouraging. 99% of students consider anatomy as an essential pillar of medical science. A vast majority (94%) felt that a sound knowledge of anatomy helped them in their clinical term. However, more than 50% termed anatomy was difficult to understand and more than two-third agreed to the question that the duration of teaching anatomy should not be limited to one and a half year. Though 73% placed anatomy apart with clinical subjects. More than 80% compared teaching anatomy as favorable as treating a patient. In Bangladesh, lack of satisfactory job opportunities and adequate research facilities limits the uptake of anatomy as a career option. Even with a modified curriculum two third were willing to become an anatomist. A formal course in teaching was welcomed by most in case they sought to become anatomist.
