The cause of maldistributed capillary perfusion in hemorrhagic shock was investigated in a combined in vivo and in vitro study. The cat tenuissimus muscle was observed by vital microscopy before and after withdrawal of 45% of the blood volume. The induced shock conditions reduced the number of perfused capillaries about 50%. Close examination of the(More)
A precision measurement by the Alpha Magnetic Spectrometer on the International Space Station of the positron fraction in primary cosmic rays in the energy range from 0.5 to 350 GeV based on 6.8 × 10(6) positron and electron events is presented. The very accurate data show that the positron fraction is steadily increasing from 10 to ∼ 250  GeV, but, from 20(More)
Quantification and qualification of climacteric symptoms had been described by Kupperman et al in 1953. New findings and ideas in the following forty years needed a correction of Kupperman index. Two important groups reduced the essential symptoms only on two ones, vasomotoric hot flushes and genital atrophy. On the contrary, Menopause Rating Scale (MRS)(More)
We developed an ELISA system for the detection of human anti-ovarian antibodies. Bovine corpora lutea were extracted in PBS (pH 7.2) and fractionated by ultracentrifugation. Both the soluble fraction obtained after 80,000 g (S80) and the Triton-extracted membrane fraction (ST288) were used as antigens. Additionally, the luteinizing hormone (LH)/human(More)
While the regulation of progesterone secretion from the corpus luteum by LH has been convincingly demonstrated, the secretory patterns in the absence of any pituitary LH inputs are yet unclear. Consequently, we investigated the progesterone secretion by an in vitro perifusion system to characterize spontaneous progesterone release from the isolated bovine(More)
The hamster ova penetration test (HOPT) was performed in 82 patients simultaneously with in vitro fertilization of homologous oocytes (IVF). A penetration rate of greater than 20% of inseminated ova was considered to represent a positive test result. The results of HOPT correlated completely with the IVF in all couples with male factor sterility. In couples(More)
We studied whether patients with systemic lupus erythematosus can have organ-specific antibodies directed against ovaries. With a recently developed enzyme-linked immunosorbent assay system that uses both a soluble and an extractable corpus luteum antigen fraction, we detected both IgG and IgM antibodies in the sera of patients with systemic lupus(More)
We conducted sleep studies in a consecutive series of 21 children with craniofacial malformations and suspected obstructive sleep apnoea. Thirteen had sleep apnoea, and one patient with a tracheostomy could not be tested. Twelve children were admitted for initiation of treatment with nasal continuous positive airway pressure (nCPAP). Ten patients accepted(More)
To evaluate the effects of ovarian surgery on the deranged episodic gonadotrophin release of women with the polycystic ovarian disease (PCOD), we studied 11 patients with the clinical and endocrinological features of PCOD before and after laparoscopic laser coagulations of ovarian surfaces and cysts. During both occasions, blood was collected at 15-min(More)
