RESUMO
OBJECTIVE: To evaluate the effect of orally administered dienogest (DNG) for dysmenorrhea and pelvic pain associated with endometriosis. METHODS: For this study we recruited 89 patients with dysmenorrhea and pelvic pain associated with endometriosis diagnosed by laparoscopy. All patients complained of persistent dysmenorrhea and pelvic pain despite surgical treatment 6 months previously. After 6 months of DNG treatment, we used a 0 to 3 point verbal rating scale to measure the severity of disability in daily life due to dysmenorrhea and pelvic pain, and the use of analgesics. Weight gain, serum lipid and liver enzyme tests were performed before treatment and after 6 months of DNG treatment. RESULTS: Total dysmenorrhea scores assessed by the verbal rating scale significantly decreased by the end of treatment (P<0.001). The mean (±standard deviation) pain score for dysmenorrhea before and after treatment were 1.42±1.1 and 0.1±0.3, respectively. The mean non-menstrual pelvic pain scores before and after treatment were 0.52±0.6 and 0.18±0.3, respectively, showing a significant difference (P<0.001). The use of analgesics significantly decreased by the end of the treatment (P<0.001). The associated adverse effects were weight gains (in 56 of 89 patients, 63%) and uterine bleeding (in 28 of 89 patients, 31.5%). The weight gain (before treatment, 57.9±9.7; after treatment, 61.1±12.6) was statistically significant (P<0.040). CONCLUSION: This study demonstrated that orally administered DNG could be used to effectively treat dysmenorrhea and pelvic pain associated with endometriosis although the side effects of weight gain and uterine bleeding should be considered.

OBJECTIVE: This study is to compare the effects of green tea polyphenol (GTP) pre-treatment with those of GTP post-treatment on cisplatin (CP)-induced nephrotoxicity in rat. METHODS: Male Sprague-Dawley rats were randomly divided into six groups. Animals in the control group received 0.9% saline (intraperitoneal); animals in the GTP group received 0.9% saline and GTP (0.2% GTP as their sole source of drinking water); the CP group received only CP (7 mg/kg, intraperitoneal); the CP+preGTP group received GTP from two days before CP to four days after CP and the CP+postGTP group received GTP for four days after CP. CP-induced renal toxicity was evaluated by plasma creatinine and blood urea nitrogen (BUN) concentrations; kidney tissue gamma-glutamyl transpeptidase (GGT) and alkaline phosphatase (AP) activities and histopathological examinations. RESULTS: High serume creatinine and BUN concentrations were observed in CP treated rats. The GGT and AP activites were lower in kidney of CP treated rats compared to control rats. In addition, treatment with CP resulted in development of a marked tubular necrosis, and tubular dilation in kidney of rats. Pretreatment with GTP resulted in markedly reduced elevation of serum creatinine and BUN amounts and changes of GGT and AP activity in kidney induced by CP. CP-induced histopathological changes, including tubular necrosis and dilation, were ameliorated in GTP pre-treated rats, compared to CP alone or GTP post-treated rats. CONCLUSION: These results demonstrate that GTP might have some protective effect against CP-induced nephrotoxicity in rat, and GTP pre-treatment was more effective than GTP post-treatment on reduction of CP-induced renal dysfunction.

This study was carried out to investigate the possibility for seeds germination of Gastrodia elata using symbiotic fungi. Since seeds of G. elata are very small and lack an endosperm and other nutrients, their germination is difficult without requirement for external nutrients. Out of twenty six isolates collected from protocorms of G. elata and roots of native orchids inhabited in wild, two strains (H-2 and H-21) were observed to stimulate the seed germination of G. elata. The seed germination of G. elata was excellent on oak tree leaves medium. The optimal conditions for mycelial growth of symbiotic fungi were 25degrees C and pH 6.0, respectively. The mycelial growth of H-2 strain was excellent on YMA medium, while H-21 was poor on PDA medium. In case of carbon sources, the mycelial growth of H-2 and H-21 was good on media supplemented with glucose and dextrin, respectively. Calcium nitrate was good for mycelial growth of H-2 strain as a nitrogen sources, whereas urea was effective to H-21 strain.

This study was carried out to obtain the basic data for artificial culture of veiled lady mushroom (Dictyophora spp). The optimal conditions for the mycelial growth were 25degrees C and pH 5.0 for all isolates except the optimal temperature of 30degrees C for D. echinovolvata ASI 32002 and Phallus rugulosus . The optimal medium for Dictyophora spp. was PBA (potato bamboo sawdust extract agar) medium. The strain ASI 32002, D. echinovolvata , grew faster than. D. indusiata ASI 32003 and Phallus rugulosus ASI 25007 on the medium. Carbon sources such as glucose, maltose and inuline were favorable for stimulating a mycelial growth of the two strains of ASI 32002 and ASI 32003. Asparagine and glutamine appeared to be favorable to the strain ASI 32002 and ASI 32003, where as alanine, one of nitrogen source also favorable to the strain ASI 32002. The optimum C/N ratio of the two isolates of ASI 32002 and ASI 32003 was about 25 : 1 when 2% glucose as carbon source was mixed with the basal medium. While, in the case of 4% as carbon source, the optimum C/N ratio was about 30 : 1.

Sodium hypochlorite alkaline was tested against Pseudomonas tolaasii causing bacterial blotch on cultivated oyster mushroom (Pleurotus ostreatus). The minimum inhibitory concentration of sodium hypochlorite against P. tolaasii contained active chlorine (AC) at 1.4 mg/l on plate assay. The highest cultivation yield was obtained from the treatment of AC 5.7 mg/l. Treatment of sodium hypochlorite at the rate of higher than AC 11.4 mg/l resulted in reduced yields at the harvest. However, the population of total bacteria on the bed surface treated with AC 5.7 mg/l of sodium hypochlorite was maintained to some extent. Inhibitory concentration against total bacteria on the bed surface was over AC 22.8 mg/l. Mushroom mycelium was damaged and its growth strongly inhibited at the concentration of AC 200 mg/l. Mushroom caps showed yellowish symptom by chemical injury by treatments of AC 74.1 mg/l or higher. Sporocarps infected by P. tolaasii were irrevocable at any concentration of sodium hypochlorite. Routine watering with AC 5.7 mg/l from mushroom initiation to the end of picking resulted in reduced bacterial blotch incidence of 40% and 86% at two mushroom farms. The treatment resulted in higher quality mushroom production compared to that conventionally watered with tap water alone.
