Effects of Dibutyl Phthalate on Rat Sperm Production and Quality / 中国药师

Objective:To evaluate the effects of dibutyl phthalate on rat sperm production and quality. Methods:Totally 150 male rats were randomly divided into the low dose group (50 mg·kg-1), the middle dose group (200 mg·kg-1), the high dose group (1 000 mg·kg-1 ) , the blank control group and the solvent control group ( peanut oil as the control) with 30 ones in each. After continu-ous administration for every 30 days, 10 rats from each group were anatomized, the weight of testes and epididymides were determined, and one side of epididymis was used to carry out the sperm analysis including counting, survival rate and morphology. Results:After intragastric administration for 90 days, the sperm count and survival rate, the weight of testis and epididymis and organ coefficient in the middle dose group and high dose group were decreased significantly(P<0. 05 or 0. 01). Conclusion:The long-term administration of dibutyl phthalate at high dose exhibits notable toxicity on rat reproductive function.

Effect of a straw-derived xylooligosaccharide on broiler growth performance, endocrine metabolism, and immune response.

The aim of this work was to evaluate the effect of 3 levels of supplemental xylooligosaccharides (XOS) from straw on the growth performance, endocrine metabolism, and immune response of broiler chickens. Day-old, healthy Arbor Acres broilers (n = 192) received a basal diet of maize-soybean meal and, depending on the group to which they were allocated, no additive (control group) or the following experimental treatments for 59 d: treatment 1: 5 g XOS/kg; treatment 2: 10 g XOS/kg; and treatment 3: 20 g XOS/kg. By day 59 the body weight gain of the chickens receiving treatment 2 had increased by 9.44% (P < 0.01) over the gain of the control group. The levels of serum triiodothyronine, thyroxine, and insulin on day 44 were significantly higher in the treatment groups than in the control group. The titers of antibody to the avian influenza H5N1 virus on day 24 were also significantly higher in the treatment groups than in the control group, and on day 59 the titer of the chickens receiving treatment 2 were still significantly increased (P < 0.05). Thus, the addition of XOS to feed can increase growth performance, enhance endocrine metabolism, and improve immune function in broiler chickens.

L'objectif de ce travail était d'évaluer les effets de trois niveaux d'un supplément de xylooligosaccharides (XOS) provenant de la paille sur les performances de croissance, le métabolisme endocrinien, et la réponse immunitaire de poulets à griller. Des poussins à griller en santé âgés d'un jour (n = 192) de race Arbor Acres ont reçu une alimentation de base maïs-soya et, selon le groupe auquel ils ont été assignés, aucun additif (groupe témoin) ou pendant 59 j le traitement expérimental suivant : traitement 1 : 5 g XOS/kg; traitement 2 : 10 g XOS/kg; et traitement 3 : 20 g XOS/kg. Au jour 59, le gain de poids corporel des poulets recevant le traitement avait augmenté de 9,44 % de plus (P < 0,01) que le gain du groupe témoin. Les niveaux sériques de triiodothyronine, de thyroxine et d'insuline au jour 44 étaient significativement plus élevés dans les groupes de traitement que dans le groupe témoin. Les titres d'anticorps contre le virus de l'influenza aviaire H5N1 au jour 24 étaient également significativement plus élevés dans les groupes de traitement que dans le groupe témoin, et au jour 59 les titres des poulets recevant le traitement 2 étaient encore significativement augmentés (P < 0,05). Ainsi, l'ajout de XOS à l'alimentation peut augmenter les performances de croissance, augmenter le métabolisme endocrinien et améliorer la fonction immunitaire des poulets à griller.(Traduit par Docteur Serge Messier).

Effects of Ru'ai Shuhou Recipe on 5-year recurrence rate after mastectomy in breast cancer / 中西医结合学报

OBJECTIVE: To observe the effects of Ru'ai Shuhou Recipe (RSR), a compound traditional Chinese herbal medicine, on 5-year recurrence rate after mastectomy in breast cancer. METHODS: A total of 300 patients with breast cancer were divided into two groups: treatment group and control group. The patients in the treatment group were treated with Western medicine and RSR, and the patients in the control group were treated only with Western medicine (the same as the treatment group). In the two groups, the 5-year recurrence rates after mastectomy in breast cancer were investigated. RESULTS: Thirty-four breast cancer patients were lost to five-year follow-up during the course of investigation, and 266 breast cancer patients went through the evaluation. The 5-year recurrence rate after mastectomy in the treatment group was significantly lower than that in the control group (P<0.05). The recurrence rate after mastectomy was influenced by positive lymph node, primary breast tumor size, clinical stage, and patients' health status. There was significant difference in the 5-year recurrence rates between the two groups (P<0.05) under the following conditions, such as the positive lymph nodes more than four, the primary breast tumor larger than two centimeters, and in the clinical stage II and III, estrogen receptor (ER)-positive/progesterone receptor (PR)-positive and ER-negative/PR-negative. The recurrence rate was not associated with the operation method and age distribution. CONCLUSION: RSR can reduce the 5-year recurrence rate after mastectomy in breast cancer.

Clinical observation of Ruyiping in preventing recidivation and metastasis of breast cancer / 中西医结合学报

OBJECTIVE: To observe the effect of Ruyiping, a traditional Chinese compound herbal medicine composed of 5 Chinese herbs for removing toxic materials and dissipating nodules from Runing II, another traditional Chinese compound herbal medicine for treating breast cancer, in preventing recidivation and metastasis in breast cancer patients after operation. METHODS: Eighty patients with breast cancer after operation were randomly divided into Ruyiping group and Runing II group, and prescribed Ruyiping and Runing II on the basis of chemotherapy, radiotherapy and endocrine therapy respectively for two years. RESULTS: There were two patients with metastasis and three patients lost to follow-up in Ruyiping group and three and two in Runing II group. The recidivation and metastasis rates were 5.41% and 7.89% respectively. The difference between the two groups was not statistically significant (P>0.05). The difference of disease-free survival time between the two groups was also not statistically significant. CONCLUSIONS: The effect of Ruyiping in preventing recidivation and metastasis is similar to that of Runing II. Ruyiping is the essential component of Runing II for preventing recidivation and metastasis. The result provides some clinical evidences for the theory that "Yudu Pangcuan" (vestigial poison invasion elsewhere) is the essential pathogenesis of breast cancer's recidivation and metastasis and the utilization of "Sanjie Jiedu" (dispersing accumulation and detoxification) is the therapeutic principle in preventing recidivation and metastasis after operation.

Breast cancer pathogenesis of stagnation of phlegm, poison and blood stasis: rationale and clinical application in traditional Chinese medicine / 中西医结合学报

Breast cancer is called "Ruyan" in literature of traditional Chinese medicine. We synthesized the ancient and contemporary discussions and raised the theory that "Duxie" (poisonous pathogenic factor) is the etiological factor and pathologic product through the whole course of breast cancer. "Liuyin Fudu" (latent poison of six exogenous pathogenic factors) and "Qiqing Yudu" (stagnant poison of seven emotions) are the main etiological factors affecting the breast cancer occurrence. "Aidu Neisheng" (internal product of cancer poison) is the essential change in breast cancer occurrence. "Tandu Yujie" (stagnation of phlegm, poison and blood stasis) is the essential pathogenesis of the breast cancer's development. "Yudu Weiqing" (vestigial poison) is the main pathogenesis of breast cancer after operation. "Yudu Pangcuan" (vestigial poison invasion elsewhere) is the key pathogenesis of recurrence and metastasis after operation. "Sanjie Jiedu" (dispersing accumulation and detoxification) is an important therapeutic principle in breast cancer's treatment after operation. The "Tandu Yujie" pathogenesis theory and "Sanjie Jiedu" therapeutic principle developed the theory about breast cancer in traditional Chinese medicine, and have some clinical application value.
