INTRAFALLOPIAN PRESSURE (IFP) OF HUMAN AND RABBIT

我们发现输卵管在管内有自己的压力。我们测量了人和兔的输卵管内压。并估算输卵管分泌物的流量。[方法]1.人体IFP的测定。Teflon导管(3法式)经宫颈插入输卵管。在宫腔镜控制下，将导尿管的顶端准确地放置在子宫输卵管连接处内侧1 cm处。输卵管内注入二氧化碳气体(CO_2)或生理盐水加吲哚红。CO2和生理盐水的注射速度分别为30ml/min和4ml/min。注射压力以IFP的形式测量，IFP以图形方式记录。我们将宫腔造影PNEUMOTUBATION试验(HKPT)命名为宫腔镜加CO2的IFP测量系统。使用宫腔镜和生理盐水的系统也被命名为宫腔镜术中水化试验(HKHT)。HKPT和HKHT16条输卵管通畅，年龄29(+-)4(M()+-()S.E.)。2.Me…兔IFP的进一步测定。成年雌性大白兔10只，体重2.5 kg。下腹纵向切开约3 cm。阴道加长0.5 cm的切口处。经腹部经阴道插管，经宫腔置入输卵管。导尿管顶端恰好位于输卵管内侧1 cm处，输卵管内注入含吲哚红的生理盐水。注射压力按IFP.3进行测量。兔部分IFP的测定。使用较薄的聚四氟乙烯阴极(外径0.5 mm，内径0.3 mm)。导管的顶端放置在输卵管的输卵管扩张部、峡部或间质。用Camino系统测量输卵管各部分的稳态IFP。Camino系统是一种采用光纤传感器的计算机压力测量系统。4.兔输卵管各部分内径和长度的测量。用兔输卵管作输卵管造影术，测量输卵管张口、输卵管间质和输卵管的内径和长度。5.兔输卵管分泌物流量的理论估算。F=[结果]1.人的IFP。节律性收缩约6次/分钟。接触期IFP分别为103.1(SY.+-)3.8毫米汞柱和84.8(SY+-)10.4毫米汞柱；舒张期IFP分别为86.6(SY.+-.)3.2毫米汞柱和72.3(SY.+-.)2.4毫米汞柱。香港理工大学为5.8人，香港理工大学为5.2人。IFP或兔子。兔的IFP为48.3士.+-.2.1毫米汞柱。未记录到输卵管节律性收缩。3.兔部分IFP。兔输卵管扩张部、峡部和肠系膜的IFP分别为0、0.5、25.2、2.2、69.2、8.0 mm Hg。4.输卵管各部分的内径和长度。肌腹内径为1.15 mm，间质内径为0.55 mm，间质内径为0.25 mm。椎弓、峡部和间质的长度分别为15.8、3.3、43.7、8.2、4.2、0.5 mm。5.输卵管分泌物流量的估算。实验测得兔输卵管肌腹、峡部和间质的输卵管分泌物流量分别为0、37.1、43.2微升。[讨论]本文首次报道IFP。HKPT和HKHTIFP值不同，这两种测量系统以注射压力作为IFP，因此IFP受注射速度和注射物质的影响。输卵管分泌物流率的真实值已经由Gott报告。我们的价值是戈特价值的两倍。本研究中的流量是通过IFP、半径、长度和粘度得到的。采用修正后的粘度值，得到的流速值可能与戈特值相近。较少

We discovered that oviduct has own pressure in the duct. We measured intrafallopian pressure (IFP) of human and rabbit. And we estimated flow rate of oviduct secrete.[METHOD]1. Measurement of IFP of human. Teflon catheter (3 french size) was transcervically inserted into oviduct. The top of the catheter was exactly placed at 1 cm inside from the uterotubal junction under hysteroscopic control. Carbon dioxide gas (CO_2) or saline with indigocarmine was injected into the oviduct. Injection speed of CO_2 and saline was 30ml/min, and 4ml/min, respectively. Injection pressure was measured as IFP.IFP was kimo-graphically recorded. We named THE HYSTEROSCOPIC KIMOGRAPHIC PNEUMOTUBATION TEST (HKPT) as IFP measuring system using hysteroscope and CO2. Also the system using hysteroscope and saline was named THE HYSTEROSCOPIC KIMOGRAPHIC HYDROTUBATION TEST (HKHT). The good patent human oviducts (n=16) were used for HKPT and HKHT.The age of the subjexts was 29 (〕SY.+-.〔) 4 (M (〕SY.+-.〔) S.E.). 2. Me … More asurement of IFP of rabbit. Female mature white rabbit (n=10, body weight=2.5Kg) was used. About 3 cm of longitudinal lower abdominal incision was carried out. And 0.5 cm incision was added into vaginal duct. Teflon ccatheter was transabdominally inserted from the vaginal duct into oviduct via uterine cavity. The top of the cathter was exactly placed at 1 cm inside from the UTJ.Saline with indigocarmine was injected into the oviduct. Injection pressure was measured as IFP.3. Measurement of partial IFP of rabbit. Thinner teflon cathter (outside diameter 0.5 mm, inside diameter 0.3 mm) was used. The top of the catheter was placed at amplla, isthmus, or interstitialis of the oviduct. And stationary IFP at each part of the oviduct was measureed with Camino system. Camino system is the computorized pressure measuringsystem with optic fiber transducer. 4. Measurement of inside radius and length of each part of oviduct of rabbit. Hystero-salpingo-graphy of rabbit was carried out in order to measure inside radius and length of amplla, istmus, and interstialis of oviduct. 5. Theoretical estimation of flow rate of oviduct secrete of rabbit. F=[RESULTS] 1. IFP of human. Rhythmical contraction about 6 times/min. was recoreded with HKPT and HKHT.IFP at contaction phase was 103.1 (〕SY.+-.〔) 3.8 mmHg by HKPT, and 84.8 (〕SY.+-.〔) 10.4 mmHg by HKHT.IFP at diastolic phase was 86.6 (〕SY.+-.〔) 3.2 mmHg by HKPT, and 72.3 (〕SY.+-.〔) 2.4 mmHg by HKHT.Exact contraction times/min. was 5.8 by HKPT, and 5.2 by HKHT.2. IFP or rabbit. IFP of rabbit was 48.3 (〕SY.+-.〔) 2.1mmHg. Rhythmical contraction of the oviduct was not recorded. 3. Partial IFP of rabbit. The IFP of the amplla, isthums, and intestitialis of rabbit oviduct was 0 (〕SY.+-.〔) 0.5 mmHg, 25.2 (〕SY.+-.〔) 2.2 mmHg, 69.2 (〕SY.+-.〔) 8.0 mmHg, respectively. 4. inside radius and length of each part of the oviduct. Inside radius of amplla, istumus, and interstitialis was 1.15 mm, 0.55 mm, 0.25 mm, respectively. And the length of amplla, isthmus, and interstitialis was 15.8 (〕SY.+-.〔) 3.3 mm, 43.7 (〕SY.+-.〔) 8.2 mm, 4.2 (〕SY.+-.〔) 0.5mm, respectively. 5. Estimation of flow rate of fallopian secrete. The flow rate of the fallopian secrete/hr at amplla, isthmus, and interstitialis of the oviduct of rabbit was estimated as 0 mul, 37.1 mul, 43.2 mul, respectively.[DISCUSSIONS] This is the first report on IFP.The concept of IFP is established in this study. Difference was observed between IFP values by HKPT and HKHT.These measuring system use injection pressure as IFP.Therefore, IFP was affected by injection speed and injection substances. Real value of flow rate of the oviduct secrete was already reported by Gott. Our value was 2 times higher than Gott's value. Flow rate in this study was obtained from IFP, radius, length, and viscosity. Corrected value of viscosity is used, the flow rate value is probably similar with Gott's value. Less
