Histological specimens of recent implantation sites are the basis of our current concept on human embryo implantation and placental development. In the Carnegie Collection maternal red blood cells were detected early in the primitive intervillous space (10th-12th day after conception). These cells were localized to the trophoblastic lacunae and originated from distended peripheral maternal sinusoids (Kaufmann, 1981). The classical theory states that progressively more and more maternal vessels are tapped. A true maternal blood flow is established around the 29th day. Dynamic investigations of human placental development in vivo are scarce and hampered by ethical considerations and the absolute requirement to refrain from using non aggressive and potentially harmful techniques. Despite these limitations such studies provide new insights that surprisingly contradict our previously and seemingly definitely established knowledge of the early phases of placental vascularization, and lead us to conclude that there is an absence of maternal blood circulation in the intervillous placental space (IVS) during the 12 first weeks of human pregnancy.

The quantum yield of singlet oxygen production by eight newly synthesized sulfur and selenium analogs of psoralen irradiated with UV-A (366 nm) has been determined in CCl4 with the help of the steady state luminescence technique. The new psoralen derivatives are generally better singlet oxygen producers than psoralen itself. In particular, the replacement of selenophene for furan and/or of thiopyrone for pyrone induces an important enhancement of the singlet oxygen quantum yield. [less ▲]

The effect of estradiol-17β (E2) supplementation on superovulation with (PMSG) or (FSH) was investigated in Swamp buffalo. Sixty-eight buffalo were treated in seven groups. Group 1 served as control and was superovulated by standard PMSG or FSH treatment used in routine bovine embryo transfer protocols. Group 2 was superovulated by standard PMSG regimen plus two injections of E2 at a 48 h interval beginning one day before the onset of gonadotropin treatment (short-term supplementation) for a total dosage of 2.5 mg E2; Groups 3 and 4 received the same regimen as Group 2, but in doses of 5.0 and 7.5 mg E2, respectively. Group 5 received the standard FSH regimen (40% LH). Group 6 received short-term E2 (7.5 mg) supplementation of FSH-p. Group 7 was superovulated by standard FSH regimen (40% LH) plus three injections of E2 at 48–72 h intervals beginning five days before the onset of gonadotropin treatment (long-term supplementation) for a total dosage of 7.5 mg E2. The number of corpora lutea (CL) and follicles ≥ 8 mm in diameter were recorded by palpation per rectum and after slaughter. The mean numbers of CL and follicles were 0.99, 5.8, 8.0, 10.6, 4.0, 3.9, 8.1 and 0.25, 6.8, 6.2, 6.2, 1.6, 0.0, 4.1 for Groups 1, 2, 3, 4, 5, 6, 7, respectively. In Group 7, the rates of nonsurgical and postmortem embryo recovery were 46 and 90.4%, respectively and 54.4% of the collected ova were fertilized. These results indicate the possibility of producing viable embryos in buffalo by using E2 supplementation for the gonadotropin treatment. [less ▲]

The aim of this study was to determine the role of octreotide administration in acromegalic patients as a preparation for selective adenomectomy using transsphenoidal route. Octreotide was administered for 3 to 6 weeks before surgery in 12 patients and for 4 to 39 months in 25 patients. The clinical response was judged as excellent or good in 10 of 12 patients from group I and in 23 of 25 patients from group II. Marked reduction (ie, greater than 50% of initial values) in serum growth hormone (GH) levels was seen in all patients, with levels to less than 5 micrograms/L in 68% of patients and less than 2 micrograms/L in 27%. Insulin-like growth factor 1 (IGF-1) levels decreased to within normal limits in half the cases. During long-term treatment, an escape phenomenon could be seen. Varying degrees of tumor shrinkage were seen in more than 50% of cases. During surgery, with regard to the relative ease or difficulty in removing the tumor, the consistency of the tumor and the separation of normal from pathological tissue, no significant difference was observed between patients given octreotide and those from control series. Morphological changes in adenomatous tissue were rather small. The surgical outcome was similar in the pretreated series as in the control series, except in enclosed adenomas, which showed a tendency to a higher success rate. Since octreotide improves both the clinical condition and hormonal parameters and induces varying degrees of tumor shrinkage, it is potentially useful as an adjunct to surgery. Morphological data suggest that octreotide exercises a functional inhibitory effect on GH release. [less ▲]

Techniques and methods required for accurate and reproducible measurements of transdiaphragmatic pressure (Pdi), were studied in seven-week and five-month-old calves. Since reliable pleural pressure measurement in cattle has already been described, separate experiments were conducted to compare retrodiaphragmatic pressures measured (i) with balloon-catheters and needle catheters, (ii) before and after eructation and (iii) in the ruminal and in the peritoneal cavities. Whereas respiratory-induced pressure changes were equally transmitted throughout the rumen content, a marked anteroposterior damping was observed as the recording site in the abdominal cavity was moved away from the diaphragm (P < 0.0001). It was concluded that the most appropriate and accurate way to measure Pdi changes in polygastric animals is to measure the pressure changes existing in the mid-thoracic portion of the oesophagus and in the liquid content of the rumen with balloon-tubing units. Neither growth- and diet-related rumen enlargement nor eructation, which are two typical characteristics of ruminants, altered the reliability of retrodiaphragmatic pressure measurements in the two age groups studied.
