母猪不孕症的针灸治疗

针灸治病是通过刺激腧穴,疏通经络,以调节机体的阴阳气血、脏腑功能、体表肌肤及筋骨百骸得以濡养等,使其发挥正常的生理功能,从而达到治疗疾病的目的。主要对性成熟后不孕母猪进行针灸治疗,结果其机体恢复正常,且正常受孕而产仔。表明针灸治疗对母猪不孕症的治疗具有重要的指导和参考意义。     

卵巢机能无障碍不孕症奶牛的细菌分离

确定卵巢机能无障碍子宫内膜炎不孕症奶牛子宫内细菌的感染状态.在调查奶牛不孕症的基础上,对临床确诊为卵巢机能无障碍子宫内膜炎不孕症奶牛的子宫内细菌进行分离鉴定.调查的853头奶牛中患不孕症的占11.8%,其中卵巢机能无障碍子宫内膜炎不孕症奶牛占66.3%,其他原因不孕症奶牛33.7%.卵巢机能无障碍子宫内膜炎不孕症奶牛的子宫内容物均被测定有细菌存在,而对照健康奶牛子宫内容物未有分离到细菌.从临床确诊的67例卵巢机能无障碍子宫内膜炎不孕症奶牛的子宫内容物中,分离到细菌菌株119株,其中葡萄球菌36株、链球菌40株、大肠杆菌36株、变形杆菌4株、芽孢杆菌1株、化脓棒状杆菌1株.本研究卵巢机能无障碍子宫内膜炎不孕症奶牛子宫内的致病菌主要是葡萄球菌、链球菌、大肠杆菌,多为2种细菌混合感染.     

杨正望教授治疗PCOS性不孕验案举隅

多囊卵巢综合征（Polycystic ovary syndrome,PCOS）是目前青春期、育龄期女性最常见的内分泌及代谢性疾病之一。由于排卵功能障碍使PCOS患者受孕率降低,且流产率增高,PCOS成为生育期妇女不孕的重要原因。杨正望教授对PCOS性不孕的病因病机及其中西医治疗均有其独到的见解,认为本病基本病机为“肾、脾、肝三脏功能失调为本,痰湿、瘀血形成为标”,数种病因病机常相互错杂,同时并存,导致多种症状同时出现,治疗上三因制宜,擅长运用中药、西药、针灸、耳穴压豆等多种方法综合治疗,临床疗效显著。     

精浆中催乳素浓度与精子活动力的关系及临床意义

目的 :探讨精浆中催乳素 (PRL)浓度与精子活动力和活动率的关系。方法 :选择不育症门诊中 6 0例男子进行精液分析 ,按精子活动力和活动率分成 A组 (活动力 ～ 级 ,活动率 >5 0 % )和 B组 (活动力 ～ 级、活动率≤5 0 % )。应用磁分离酶联方法测定其精浆中 PRL 浓度。结果 :A组精浆中 PRL 浓度为 (14.85± 4.0 5 ) μg/ L,B组为 (19.5 5± 4.85 ) μg/ L,A组与 B组之间 PRL 浓度差异有显著性 (P<0 .0 0 1)。精子活动力和活动率与精浆中 PRL 浓度呈负相关。结论 :血清和精浆中 PRL以不同方式进行调节 ,精浆中 PRL 来源于精囊 ,其浓度的高低影响着精子活动力和活动率。临床上不育症患者 ,采用分步射精法 ,摒弃后半部分精液 ,可能提高精子功能状态和受孕率

Clinical presentation,treatment and possible causes of persistent endometrial cups illustrated by two cases

Persistent endometrial cups are relatively rare in the mare and the occurrence in 2 successive pregnancies, as described in this issue, is an intriguing finding. This article describes an additional 2 cases of endometrial cups persisting in excess of 12 months in mares that had experienced pregnancy loss. Both mares demonstrated irregular ovarian activity in the form of repeated formation of haemorrhagic anovulatory follicles. A definitive diagnosis was made by visualisation of cup tissue by hysteroscopy and demonstration of equine chorionic gonadotropin (eCG) in the mares' serum. Biopsy of endometrial cups was made under visual direction and the mares were treated by chemical curettage with kerosene. The clinical presentation, treatment and possible causes of persistent endometrial cups are reviewed and discussed.     

Genital Disorders,Linear and Testicular Characteristics in Menz Rams

Clinical examination, bodily condition score (BCS), heart girth (HG), body length (BL), wither height (WH), and scrotal circumference (SC) were assessed on 486 mature Ethiopian Menz rams, on small farms, in local markets, and at the main abattoir in Addis Ababa from December 1994 to April 1995. Almost 27% of the rams were found to be unfit for breeding. Poor general condition, mainly in the form of respiratory disorders, was seen in 1.2% of the rams. Balanoposthitis, epididymitis and orchitis were the most common pathological conditions, affecting the external reproductive organs in 14.6%, 4.5% and 4.1% of the rams, respectively. Testicular calcification, cysts and testicular haemorrhagic lesions were detected in 4, 6 and 8, respectively, of the 60 rams examined at necropsy. The BCS, HG, BL and WH averaged 2.1±0.5, 67.7±5.0 cm, 60.1±4.5 cm and 60.1±4.3 cm, respectively. The mean SC was 25.5±3.9 cm and did not vary significantly with age (p>0.05). Among the linear body measurements, the highest correlation was between BL and WH (r = 0.66). SC was found to be most closely correlated to HG (r = 0.46). More investigations into the relationship between the present findings and actual fertility, and on their practical application in the selection of rams for breeding is recommended.     

Infection of the Bovine Female Genital Tract with Chlamydia psittaci as a Possible Cause of Infertility

Contents: Chlamydia psittaci was isolated in embryonated chicken eggs via the yolk sac route from ten (16,7%) vaginal andlor endometrial mucosal scrapings of 60 slaughter cows. Simultaneous fecal shedding of chlamydiae was found in four animals. Chlamydial infections of the genital tract were frequent (p < 0,01) when there were endometrial inflammatory lesions together with the failure to detect other bacterial pathogens in the uterus.
