[Radionuclide examination of kidney function in children with vesico-renal reflux].

The authors report on their experience with the assessment of radionuclide, separated renal clearance in children with unilateral vesicorenal reflux. The radiopharmaceutical preparation 131I-orthoiodohippuran was used, the result of the examination was a separated effective renal plasma flow (ERPF) which was assessed according to a modification of Oberhausen's method. A total of 28 children were examined. In 8 children the vesicorenal reflux was grade III and IV, in 20 children a unilateral grade II vesiculorenal reflux was involved. In both groups the authors demonstrated a significant functional deficit (p less than 0.001) of the kidney with the reflux despite the fact that in the second group all children had normal excretory urography, a negative urinary sediment and a normal creatinine and urea blood level.

Isolation of Neisseria gonorrhoeae from urine obtained by suprapubic puncture of bladders of men with gonococcal urethritis.

The authors examined three urine specimens from each of 24 men with acute gonococcal urethritis. Gonococcal concentrations in urine were 7 X 10(3)/ml to 9 X 10(8)/ml in first samples, 1 X 10(2)/ml to 5 X 10(6)/ml in midstream samples, and, in the terminal samples from only 22 men, 8 X 10(4)/ml. A further 17 men with symptomless gonococcal urethritis were examined. Seven of them yielded 1 X 10(2)/ml to 2.5 X 10(5)/ml in first samples and 5 X 10(5)/ml in midstream samples, and only two yielded 5 X 10(1)/ml in final samples. All 24 men with acute gonococcal urethritis, and seven of the men with symptomless gonococcal urethritis who had yielded N gonorrhoeae in midstream urine samples, were examined by suprapubic puncture before morning voiding. Four of the 24 men with acute gonococcal urethritis were found to have infection that had ascended into the bladder.

X-ray changes in the kidneys of children with orthostatic proteinuria.

In 38 patients with orthostatic proteinuria (O.P.) and in 31 children of the control group (C) roentgenograms of excretory urography have been compared, made in the standing erect and in the lying down posture. In children with O.P. significantly more frequent and more expressive ptosis of the kidneys during orthostasis was found than in the controls. In children with O.P. disturbed urine outflow was found in 36.8%, while in children of the control group only in 3.2%. On the basis of the results obtained relations between haemodynamic changes in ptosis of the kidneys, disturbed urine outflow and the origin of O.P. are analysed.

[Submicroscopic changes in ciliated cells of the epithelium of the oviduct in cows during the estrus cycle].

The submicroscopic changes in the ciliary cells of the ampullar part of oviduct are of qualitative as well as quantitative nature. The mitochondria are mainly located in the supranuclear region. They are small, having densely arranged lamelliform cristae and dense matrix. They have the largest volume in metoestrus and the highest number and the largest surface already during oestrus. The volume and surface of granular endoplasmic reticulum culminates already during pro-oestrus. The reticulum occurs mainly over the nucleus where it produces tubuli densely covered with ribosomes which begin to dilate already during pro-oestrus. The Golgi apparatus and the membranes of smooth reticulum are poorly developed and their quantitative changes during the cycle are not significant. Various forms of lysosomes, whose volume reaches its maximum in dioestrus and during pro-oestrus, constitute a constant component of cytoplasm. Secretory granules occur only rarely in these cells. Kinocilia grow from the basal corpuscles and are more frequent on cells with a light cytoplasm. Higher-density cells have more micro-villi between kinocilia. Deciliation with the disintegration of membrane, filaments and often also the basal corpuscles is observed during metoestrus and at the beginning of dioestrus. Reciliation begins with the formation of basal corpuscles and their replication at the end of dioestrus and in pro-oestrus. The frequency of ciliary regeneration is comparatively small.

[Submicroscopic changes in the secretory cells of the epithelium of the bovine oviduct during the estrous cycle].

The secretory cells of the ampullar part of bovine oviduct are characterized by the secretory granules in cytoplasm. Their apical surface is covered with a small amount of micro-villi. Among the organellae, the Golgi apparatus is well-marked: during the sexual cycle it produces several centres. Its volume and surface reach their maxima before ovulation. The mitochondria are large and have a smaller amount of cristae. Their number culminates in pro-oestrus and their volume and surface area in metoestrus. The tubuli of granulated endoplasmic reticulum dilate during pro-oestrus and oestrus and some of them later disintegrate. They reach the largest volume and surface in pro-oestrus when the highest number of polyribosomes also occurs. Secretory granules are produced throughout the cycle as low-density spherical corpuscles covered with a simple membrane: in the course of maturation they change into high-density corpuscles and some of them break down. Their number and volume culminate in metoestrus when they are secreted on a mass scale. The population of secretory cells is heterogeneous. Besides dense and light cells, thin granules. Some cells lose contact with the basal membrane and their extrusion occurs mainly during metoestrus.
