ABSTRACT
Objective@#To investigate the effect of saw palmetto extract (SPE) on the reproductive function of rats with chronic prostatitis (CP).@*METHODS@#Forty male SD rats were equally randomized into groups A (blank control), B (blank control + SPE, C (CP model control) and D (CP model + SPE), and the CP model was made by injection of 1% λ-carrageenan solution into the prostate. The animals in groups A and C were gavaged with normal saline while those in groups B and D with SPE at 0.10 g/kg/d, all for 30 successive days. After drug withdrawal, the rats were mated with female ones in the ratio of 1∶1) and sacrificed 7 days later, their bilateral epididymides collected for detection of sperm count and motility. The numbers of pregnancies and fetuses were recorded and compared among different groups.@*RESULTS@#Compared with the rats in group A, those in group C showed a marked decrease in epididymal sperm motility (［68.01 ± 1.80］% vs ［62.59 ± 4.82］%, P 0.05). There were no statistically significant differences in the count of epididymal sperm, rate of pregnancy and number of fetuses between group A and the other groups (P > 0.05).@*CONCLUSIONS@#SPE can improve the semen parameters of CP rats, and has no adverse effect on the rate of pregnancy and number of fetuses.
ABSTRACT
Objective@#To assess the clinical efficacy of the saw palmetto fruit extract (SPFE) in the treatment of lower urinary tract symptoms (LUTS) in patients with type ⅢA prostatitis.@*METHODS@#This retrospective study included 54 cases of type ⅢA prostatitis treated in the Outpatient Department of our hospital from January to December 2015. The patients were aged 35.06 ± 5.85 years, with a mean disease course of 3.8 ± 2.1 years, and all received oral medication of SPFE Capsules at the dose of 320 mg qd for 12 weeks. We assessed the therapeutic effects by comparing the NIH-chronic prostatitis symptom indexes (NIH-CPSI), voiding diary, International Prostate Symptom Scores (IPSS), and results of urodynamic examination before and after treatment.@*RESULTS@#Compared with the baseline, both NIH-CPSI and IPSS were significantly decreased after medication (27.61 ± 3.76 vs 18.6 ± 5.34, P <0.01; 20.44 ± 4.51 vs 10.96±4.62, P <0.01), and urodynamic examination and voiding diary showed dramatic post-medication improvement in the average urinary flow rate (［8.05±1.42］ vs ［12.05±2.60］ ml/s, P <0.01 ), maximum urinary flow rate (［14.22±1.74］ vs ［21.32±4.51］ ml/s, P <0.01), residual urine volume (［46.15±16.57］ vs ［14.55±10.21］ ml, P <0.01), maximum urethral closure pressure (［76.52±3.53］ vs ［65.32±4.75］ cm H2O, P <0.01), mean urinary volume (［124.63±40.55］ vs ［285.93±58.68］ ml, P <0.01), urination frequency (16.96±4.17 vs 8.96±2.50, P <0.01), and nocturia frequency (8.94±3.23 vs 3.15±1.90, P <0.01). No apparent adverse reactions were observed in any of the patients.@*CONCLUSIONS@#SPFE Capsules can safely and effectively improve LUTS and thus the quality of life of patients with type ⅢA prostatitis.

ABSTRACT
Se presenta el caso de un hombre de 52 años con cuadro clínico de hiperazoemia de origen no claro, quien tenía como antecedentes de importancia hipertrofia prostática benigna (HPB) y prostatitis crónica, tratadas durante varios meses con palmito salvaje o palma enana americana (Serenoa repens o Saw palmetto); medicamento a base de extractos de los frutos de esta planta y a quien en la última semana se le había prescrito dosis elevadas (960 mg/d). Sus estudios de laboratorio demostraron una tasa de filtración glomerular (TFG) de 60 mililitros por minuto y la suspensión del medicamento fitoterápico logró restauración de su función renal a niveles normales. Se discute los mecanismos a través de los cuales el palmito salvaje podría ocasionar hiperazoemia.

This study was to investigate the role of complementary and alternative medicine in the prevention and treatment of benign prostatic hyperplasia. For this purpose, a randomized, double-blind, placebo-controlled trial was performed over 12 months on 47 benign prostatic hyperplasia patients with average age of 53.3 years and international prostate symptom score over 8. Subjects received either sweet potato starch (group A, placebo, 320 mg/day), pumpkin seed oil (group B, 320 mg/day), saw palmetto oil (group C, 320 mg/day) or pumpkin seed oil plus saw palmetto oil (group D, each 320 mg/day). International prostate symptom score, quality of life, serum prostate specific antigen, prostate volume and maximal urinary flow rate were measured. In groups B, C and D, the international prostate symptom score were reduced by 3 months. Quality of life score was improved after 6 months in group D, while those of groups B and C were improved after 3 months, compared to the baseline value. Serum prostate specific antigen was reduced only in group D after 3 months, but no difference was observed in prostate volume in all treatment groups. Maximal urinary flow rate were gradually improved in groups B and C, with statistical significance after 6 months in group B and after 12 months in group C. None of the parameters were significantly improved by combined treatment with pumpkin seed oil and saw palmetto oil. From these results, it is suggested that administrations of pumpkin seed oil and saw palmetto oil are clinically safe and may be effective as complementary and alternative medicine treatments for benign prostatic hyperplasia.

O objetivo deste trabalho foi avaliar a utilização de fitoterápicos a base de saw palmetto na terapia sintomática da hiperplasia benigna da próstata (HBP) por médicos urologistas da cidade de Porto Alegre. Consistiu em um estudo transversal, exploratório, por meio de entrevista semi-estruturada aplicada a urologistas de Porto Alegre. A amostra foi obtida utilizando catálogo do plano de saúde UNIMED- Porto Alegre. A randomização foi realizada através de sistemática aleatória, sendo sorteados trinta e cinco médicos, dos quais 21 foram selecionados para realização da pesquisa através de questionário. Todos os urologistas entrevistados avaliam e tratam pacientes com hiperplasia benigna da próstata. O saw palmetto não foi citado como terapia medicamentosa de 1ª ou 2ª escolhas no tratamento da HBP. O grupo farmacológico mais freqüentemente utilizado para o tratamento da HBP foi ∝-bloqueadores. Mais da metade dos médicos entrevistados relata ter conhecimento sobre a utilização do saw palmetto, principalmente através de artigos científicos. Os resultados indicam que o saw palmetto não é prescrito pelos urologistas em Porto Alegre, todavia a maior parte destes profissionais tem conhecimento sobre sua utilização.
The aim of this work was to assess the prescription of saw palmetto phytomedicines for improving symptoms of benign prostatic hyperplasia (BPH) by urologists in Porto Alegre (Brazil). The study was transversal and exploratory consisting of a semi-structured interview with urologists. The sample was obtained from the UNIMED Catalog - Porto Alegre (Brazil). The randomization was made by chance, being selected thirty-five physicians. The first twenty-one who accepted to participate were interviewed. All the interviewed urologists treat patients with benign prostatic hyperplasia. The saw palmetto was not mentioned as the first or second choice for treating BPH. The α-blockers were the most mentioned pharmacological group. However, more than half of urologists have heard about the use of saw palmetto and most of them gathered the information in scientific papers. The results indicate that saw palmetto is not prescribed for urologists in Porto Alegre, although most of them have knowledge about this phytomedicine.
