RESUMO
Objectives: We investigate the effects of Ojayeonjonghwan (KH-204) in men with late-onset hypogonadism (LOH) symptoms.Material and methods: Initial PSA, testosterone, lipid profile and questionnaires about LOH-related symptoms were checked. After 8 weeks of the treatment (control or KH-204), questionnaires and serological tests were repeated to evaluate the efficacy of the agent. The changes of variables in each group and the difference between two groups were compared.Results: A total of 78 men were enrolled, and randomly assigned to the control group (n = 39) or KH-204 group (n = 39). Baseline characteristics of both group are comparable. AMS total score of control and KH-204 group were both improved at 8 weeks (p = .010, <.001), and there was a statistically significant difference between the two groups (favorable in KH-204 group, p = .006). At 8 weeks, total IIEF score of control and KH-204 group were both improved, and there was no statistically significant difference in the degree of improvement between the two groups (p = .303). There was no statistically significant difference of laboratory findings, in intra-group changes and inter-group comparisons.Conclusions: KH-204 was found to be effective in all LOH symptoms without changing of laboratory results. KH-204 may be safely used for treatment of male with LOH-related symptoms.

CONTEXT: Not all men presenting varicocele-associated infertility exhibit improved sperm quality or achieve pregnancy following varicocelectomy. Some combinations of specific natural herbs have been shown empirically to reduce oxidative stress and improve sperm quality. OBJECTIVE: We conducted a study to determine the effects of an herbal combination on sperm quality in varicocele-induced rats following varicocelectomy, hoping to find a new treatment approach to restore sperm quality following varicocelectomy. DESIGN: The research team designed an animal study. SETTING: The study took place in the Department of Urology at Seoul St. Mary's Hospital (Seoul, Republic of Korea). ANIMALS: Fifty white, male, Sprague-Dawley rats weighing 250 to 300 g each were used in the study. INTERVENTION: The rats were randomly assigned to 5 groups: (1) a control group (n = 10), (2) varicocele group (n = 10), (3) rats with varicocele and receiving varicocelectomy only (varicocelectomy group, n = 10), (4) rats with varicocele received varicocelectomy and oral administration with 200 mg/kg of an herbal combination for 4 wk (varicocelectomy + 200 mg/kg group, n = 10), and (5) rats with varicocele received varicocelectomy and oral administration with 400 mg/kg of an herbal com for 4 wk (varicocelectomy + 400 mg/kg group, n = 10). OUTCOME MEASURES: The study measured (1) sperm concentration and motility, (2) levels of reactive oxygen species (ROS), (3) concentrations of interleukin 6, interleukin 1ß, and tumor necrosis factor alpha (TNF-α), (4) apoptotic change, and (5) levels of heat shock protein (HSP). RESULTS: The sperm concentrations and motilities recovered after treatment in the varicocelectomy, varicocelectomy + 200 mg/kg, and varicocelectomy + 400 mg/kg groups. Significantly increased SOD and decreased ROS and cytokine levels were also observed. The apoptosis in the testes also was significantly decreased compared with the varicocele group. HSP70 in groups received varicocelectomy and administered with herbal combination was significantly decreased compared with the varicocelectomy group. CONCLUSIONS: The herbal combination was found to improve the sperm qualities, oxidative stress, and inflammation after varicocelectomy. Therefore, the herbal combination may provide a new and additional treatment for varicocele-associated infertility. For clinical application, further studies are needed to identify active ingredients in each herb and the mechanism by which each ingredient works, to standardize the herbal combination.

Purpose: To evaluate the pharmacological effects of goji berry (Lycium chinense P. Mill) in an animal model of late-onset hypogonadism (LOH).Materials and methods: Thirty 18-month-old male Sprague-Dawley (SD) rats were used as the LOH aged rat model. Rats were divided into five groups: a control group (n = 6), low concentration goji berry extract group (150 mg/kg/day) (n = 6), high concentration goji berry extract group (300 mg/kg/day) (n = 6), low concentration goji berry complex extract group (150 mg/kg/day) (n = 6), and high goji berry complex concentration extract group (300 mg/kg/day) (n = 6). After six weeks of treatment, sperm counts and motility, serum testosterone level, androgen receptor (AR) expression, oxidative stress marker, and apoptotic factors were examined.Results: Goji berry extracts increased testosterone level to 2.07 ± 0.06 pmol/L in the goji berry 150 mg/kg group, 2.39 ± 0.08 pmol/L in the goji berry 300 mg/kg group, 2.97 ± 0.03 pmol/L in the goji berry complex 150 mg/kg group, and 3.34 ± 0.04 pmol/L in the goji berry complex 300 mg/kg group compared to 1.86 ± 0.03 pmol/L in the control group, respectively (p < .05). AR expressions were increased in testis tissue significantly but were not significant in prostate tissue.Conclusions: Goji berry might improve LOH by reversing testicular dysfunction via an anti-oxidative stress mechanism without inducing prostate disease.

Purpose: We investigated the synergy effect of extracorporeal shock wave therapy (ESWT) with modified Ojayeonjonghwan (Korean herbal formula, KH-204) in an animal model of diabetes mellitus (DM)-induced erectile dysfunction (ED). Materials and Methods: Eight-week-old male Sprague-Dawley rats were used in this study. DM was induced by an intraperitoneal injection of streptozotocin. DM rats were divided into 5 groups (n=10 per group): group 1, control; group 2, DM; group 3, DM+ESWT; group 4, DM+KH-204; and group 5, DM+ESWT+KH-204. In ESWT groups, rats were treated with ESWT at the penis 3 times a week for 2 weeks under anesthesia. The KH-204 groups were treated with a daily oral dose of KH-204 for 12 weeks. After all treatments, intracavernosal pressure (ICP) was measured, and the cavernous tissues were evaluated by Masson's trichrome, immunohistochemistry and western blot analysis. Results: ICP was evaluated as a measurement of erectile function. The DM+ESWT, DM+KH-204, and DM+ESWT+KH-204 groups showed significantly restored erectile function compared with the DM group (p<0.05). Among these groups, the DM+ESWT+KH-204 group showed the highest ICP. Moreover, ESWT and KH-204 treatment restored smooth muscle contents and many parameters related to potency (vascular endothelial growth factor, neuronal nitric oxide synthase (NOS), endothelial [NOS] and platelet endothelial cell adhesion molecule-1) compared with the DM group (p<0.05). Conclusions: We confirmed the potential efficacy of ESWT and KH-204 in the treatment of ED patients using an animal model. The combination treatment of KH-204 and ESWT is expected to have good potential clinical results in the future treatment of refractory ED.

PURPOSE: Testosterone replacement therapy is an effective treatment for late-onset hypogonadism (LOH) despite a few contraindications and side-effects. The aim of this study was to determine whether modified Ojayeonjonghwan (KH-204, Korean herbal formula) improved LOH. KH-204 is a strong antioxidant herbal formula. We evaluated the effect of Korean herbal prescription on androgen receptor (AR) expression in an aged rat model of LOH. MATERIALS AND METHODS: Eighteen-month-old rats were used as aged LOH rat models. Eighteen Sprague-Dawley rats were randomly divided into three equal groups of six animals each and treated with one of the following: 1) normal control group (oral administration with distilled water, n=6), 2) KH-204 200 group (oral administration with 200 mg/kg of KH-204, n=6), and 3) KH-204 400 group (oral administration with 400 mg/kg of KH-204, n=6). After four weeks of treatment (once daily, distilled water or KH-204), serum testosterone levels, changes in testicular and epididymal weight, Western blotting analysis of AR expression and measurement of oxidative stress were examined. RESULTS: Treatment with the herbal formulation KH-204 200 mg/kg and 400 mg/kg (1) increased the weights of testis and epididymis; (2) increased the level of serum testosterone; (3) increased the level of superoxide dismutase and reduced the level of 8-hydroxy-20-deoxyguanosine; and (4) upregulated AR expression in testicular tissue. CONCLUSIONS: KH-204 might be an effective alternative for LOH. It improves antioxidant mechanisms and increases testicular AR expression without side-effects.

RESUMO
PURPOSE: Many patients with benign prostatic hyperplasia need treatment for remaining storage symptoms after surgery. Therefore, we evaluated the effect of the phytotherapeutic agent WSY-1075 on persistent detrusor overactivity (DO) after the relief of bladder outlet obstruction (BOO). MATERIALS AND METHODS: Rats were assigned to 3 groups: control (n=6), persistent DO (n=6), and persistent DO treated with the phytotherapeutic agent WSY-1075 (n=6). Persistent DO after relief of partial BOO was generated in the rat model, and 6 of the rats with this condition were orally administered WSY-1075. After 4 weeks of administration, cystometry was performed. Additionally, 8-hydroxy-2-deoxyguanosine and superoxide dismutase were measured to evaluate oxidative stress in the bladder. Pro-inflammatory cytokines, such as interleukin-8 and tumor necrosis factor-α, were analyzed, as were the M2 and M3 muscarinic receptors of the bladder. RESULTS: Significantly increased contraction pressure and a decreased contraction interval were observed in the persistent DO group after relief of BOO. Moreover, oxidative stress, pro-inflammatory cytokines, and M3 muscarinic receptors were significantly increased. After treatment with WSY-1075, significantly reduced DO was observed by cystometry in comparison with the persistent DO group. Additionally, significantly decreased levels of oxidative stress, pro-inflammatory cytokines, and M3 muscarinic receptors in the bladder were observed after treatment with WSY-1075. CONCLUSIONS: Treatment with WSY-1075 improved persistent DO after the relief of BOO mediated by antioxidative and anti-inflammatory effects. Further studies are necessary to identify the exact mechanism of the treatment effect of WSY-1075.
RESUMO
OBJECTIVE: To investigate the anti-oxidative stress and preventive effect of modified Gongjin-dan (WSY-1075) in a detrusor underactivity rat model. METHODS: Rats were randomly allocated to three groups: shamoperated (control), bladder outlet obstruction-induced detrusor underactivity (BOO-DU), and BOO-DU with WSY-1075 (WSY) groups. WSY-1075 was orally administrated to rats 200 mg daily for 2 weeks prior to the operation and 4 weeks after the operation. Bladder outlet obstruction was surgically induced in rats by ligation around the urethra avoiding total obstruction. Cystometrography was conducted on rats in each group for examination of bladders. RESULTS: Compared with the control group, bladder outlet obstruction led to a significant increase in oxidative stress with consequent changes to molecular composition, and decrease in maximal detrusor pressure (P<0.05). WSY-1075 treatment significantly suppressed oxidative stress and prevented degenerative and dysfunctional changes in bladder, as compared with BOO-DU group (P<0.05). CONCLUSION: WSY-1075 had beneficial effect on prevention of BOO-DU.

BACKGROUND: Houttuynia cordata Thunb (HC) is a traditional herbal medicine widely used in Asia for the treatment of patients with alopecia, usually in combination with other two herbal medicines (Perilla frutescens var. acuta (PFVA) and green tea (GT)). However, the effect of this herbal complex has not been clearly demonstrated. We sought to determine the hair growth-promoting effect of this herbal complex (HC, PFVA, and GT) in the animal model. METHODS: Six-week-old male C57BL/6 mice were randomly divided into four groups (negative control, finasteride (1 mg/kg) as a positive control, and two (200 and 400 mg/kg) concentrations of the herbal complex as experimental groups) and were fed its corresponding medications orally for 25 days. Hair growth was evaluated visually and microscopically. Western blot analysis for insulin-like growth factor (IGF)-1 and transforming growth factor (TGF)-ß1 was performed. RESULTS: The herbal complex exhibited hair growth-promoting activity in C57BL/6 mice. Grossly, the area of hair regrowth was 55.1 (±3.8) %, 70.2 (±6.3) % and 83.5 (±5.7) % in negative control, herbal complex 200 mg/kg and 400 mg/kg group, respectively. In histologic examination, the hair follicle count in deep subcutis was 2.6 (±0.7), 5.8 (±0.7) and 8.6 (±1.2) and the diameter of hair follicles was 11.9 (±5.0) µm, 17.4 (±3.9) µm and 22.8 (±5.2) µm in negative control, herbal complex 200 and 400 mg/kg group, respectively. The expression of IGF-1 was 0.14 (±0.01), 0.23 (±0.02) and 0.24 (±0.01) and the expression of TGF-ß1 was 0.26 (±0.01), 0.19 (±0.02) and 0.15 (±0.01) in negative control, the 200 and 400 mg/kg group, respectively. CONCLUSIONS: This data provides adequate preliminary experimental evidence to support the hair regeneration effect of this herbal complex.

The Korean herbal formulation Ojayeonjonghwan is used for improving late-onset hypogonadism (LOH) symptoms such as erectile dysfunction (ED). A previous research suggested that a modified Ojayeonjonghwan (KH-204) could be used as an alternative to the treatment for ED. The pharmacological effects were examined in different conditions, including in vitro and in vivo. We measured the survival rate of TM3 Leydig cells under the oxidative stress condition. The s.c. injection of leuprorelin was used to induce androgen deprivation. We measured serum testosterone levels, oxidative stress, and apoptosis. The results of the treatment by KH-204 (1) preserved TM3 cells from oxidative stress by improving the expression of nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1); (2) lowered the expression of transforming growth factor-beta (TGF-ß) 1/SMAD; (3) increased the average of serum testosterone in androgen-deprived male rats; (4) kept the activation of spermatogenesis; (5) upgraded the contents of 8-hydroxy-20-deoxyguanosine (8-OHdG) and degraded the contents of superoxide dismutase (SOD); and (6) reduced apoptosis. We studied that KH-204 improved testicular dysfunction in LOH. It is likely, at least in part, to degrade oxidative stress through the Nrf2/HO-1 pathway. These findings may offer credible evidences for the use of new alternative therapies to treat LOH.
