(1) Electron microscopy revealed the presence of a hitherto unreported peculiar "pilovacuolar" inclusion in numerous mitochondria, composed of an electron dense pile or rod within a vacuole, while globular or crystalline inclusions were absent.
(2) The anomaly may represent a hitherto overlooked but easily obtainable diagnostic marker.
(3) As regards other factors, however, whose causative role has hitherto been considered proven or at least very probable, no differences were found between patients and controls (e.g.
(4) This model was recently introduced into the stereology of myocardial capillaries and leads to a more accurate quantitation of the capillary network than parameters used hitherto, such as the "capillary density" (number of capillary profiles per mm2 of cross sectional area) and the "capillary-fiber ratio" (number of capillary profiles per number of myofiber profiles in cross sections).
(5) The carcinostatic effect of the hitherto unknown N-(2-cyanethylene) urea is descirbed.
(6) It is concluded that SLE is not as uncommon in black South Africans as was believed hitherto.
(7) Hitherto unsuspected biosynthetic heterogeneity is present in the glands.
(8) Hitherto performed abdominoperineal or sacroperineal procedures entailed major traumatizing surgery with an inherent risk of complications.
(9) In fact, the overall efficacy of CSFs has been outstanding for disorders hitherto viewed as otherwise refractory.
(10) It is suggested that the condition is more common than hitherto reported and is often confused with maturation arrest.
(11) One case of tubal endometrioid carcinoma has been reported previously, but the entity has not hitherto been recognized among primary fallopian tube tumors.
(12) Controlled behavioural testing confirmed the apparent agnosia but revealed that he could be trained to make a number of visual discriminations which had not been apparent from routine clinical examination and that he suffered a number of subtle sensory impairments which likewise had not hitherto been apparent.
(13) Hitherto there have been hardly any paediatric investigation into the effect of sport on children,--apart from physiological ones, (Rutenfranz).
(14) The present study has shown a hitherto unknown axo-axonic cell in the rat fascia dentata.
(15) The importance of the m. canalis ani and of the hitherto unknown transsphincteric course of the blood reflux from the arterially supplied corpus cavernosum for the pathogenesis of the hemorrhoidal disease as the adequate therapy are delineated.
(16) According to the results in hand there exists a contradiction to the opinions hitherto existing about a distinct age dependence in the bone structure and distinct sex differences in the findings of the structures of the Ist order.
(17) The progressive fusion of the neural folds during stage 10, and the closure of the rostral and caudal neuropores at stages 11 and 12, respectively, are detailed with further precision than hitherto.
(18) Hitherto, the duration of the perfusion has been extended to 10 h. After this time the endothelium was well preserved.
(19) The hitherto recommended treatment, pyrimethamine in combination with sulphonamides, is often associated with severe side-effects.
(20) These spontaneous fluctuations of the blood lithium level, a hitherto unreported phenomenon are discussed as a possible cause of the lithium intoxication.
